I don't find a specific tow rating, I found a means of figuring it, which is also part of the owners manual.
Towing a Trailer
Caution: The driver can lose control when pulling a trailer if the correct equipment is not used or the vehicle is not driven properly. For example, if the trailer is too heavy, the brakes may not work well or even at all. The driver and passengers could be seriously injured. The vehicle may also be damaged; the resulting repairs would not be covered by the vehicle warranty. Pull a trailer only if all the steps in this section have been followed. Ask your dealer for advice and information about towing a trailer with the vehicle.
Your vehicle can tow a trailer if it is equipped with the proper trailer towing equipment. To identify what the vehicle trailering capacity is for your vehicle, you should read the information in "Weight of the Trailer" that appears later in this section. But trailering is different than just driving your vehicle by itself. Trailering means changes in handling, durability and fuel economy. Successful, safe trailering takes correct equipment, and it has to be used properly.
That is the reason for this part. In it are many time-tested, important trailering tips and safety rules. Many of these are important for your safety and that of your passengers. So please read this section carefully before you pull a trailer.
Load-pulling components such as the engine, transaxle, wheel assemblies and tires are forced to work harder against the drag of the added weight. The engine is required to operate at relatively higher speeds and under greater loads, generating extra heat. What is more, the trailer adds considerably to wind resistance, increasing the pulling requirements.
If You Do Decide To Pull a Trailer
If you do, here are some important points:
" There are many different laws, including speed limit restrictions, having to do with trailering. Make sure your rig will be legal, not only where you live but also where you will be driving. A good source for this information can be state or provincial police.
" Consider using a sway control. You can ask a hitch dealer about sway controls.
" Do not tow a trailer at all during the first 1,000 miles (1 600 km) your new vehicle is driven. Your engine, axle or other parts could be damaged.
" Then, during the first 500 miles (800 km) that you tow a trailer, do not drive over 50 mph (80 km/h) and do not make starts at full throttle. This helps your engine and other parts of your vehicle wear in at the heavier loads.
" Obey speed limit restrictions when towing a trailer. Do not drive faster than the maximum posted speed for trailers, or no more than 55 mph (90 km/h), to save wear on your vehicle's parts.
Three important considerations have to do with weight:
" the weight of the trailer
" the weight of the trailer tongue
" and the total weight on your vehicle's tires
Weight of the Trailer
How heavy can a trailer safely be?
It depends on how you plan to use your rig. For example, speed, altitude, road grades, outside temperature and how much your vehicle is used to pull a trailer are all important. And, it can also depend on any special equipment that you have on your vehicle.
It should never weigh more than 2,000 lbs. (900 kg). These are total maximum weights including the load. But even that can be too heavy.
The maximum trailer weight for your vehicle can be determined from the Gross Combined Vehicle Weight (GCVW). The GCVW = curb weight + passenger's weight + cargo weight + trailer weight. The GCVW should never be more than 7,200 lbs. (3 273 kg).

Weight of the Trailer Tongue
The tongue load (A) of any trailer is an important weight to measure because it affects the total or gross weight of your vehicle. The Gross Vehicle Weight (GVW) includes the curb weight of the vehicle, any cargo you may carry in it, and the people who will be riding in the vehicle. And if you tow a trailer, you must add the tongue load to the GVW because your vehicle will be carrying that weight, too. See Loading the Vehicle for more information about your vehicle's maximum load capacity.
If you are using a weight-carrying hitch or a weight-distributing hitch, the trailer tongue (A) should weigh 10 - 15 percent of the total loaded trailer weight (B).
After you have loaded your trailer, weigh the trailer and then the tongue, separately, to see if the weights are proper. If they are not, you may be able to get them right simply by moving some items around in the trailer.
Total Weight on Your Vehicle's Tires
Be sure your vehicle's tires are inflated to the upper limit for cold tires. You will find these numbers on the Tire and Loading Information. See Loading the Vehicle. Then be sure you do not go over the GVW limit for your vehicle, including the weight of the trailer tongue.
It is important to have the correct hitch equipment. Crosswinds, large trucks going by and rough roads are a few reasons why you will need the right hitch. Here are some rules to follow:
" The rear bumper on your vehicle is not intended for hitches. Do not attach rental hitches or other bumper-type hitches to it. Use only a frame-mounted hitch that does not attach to the bumper.
" Will you have to make any holes in the body of your vehicle when you install a trailer hitch? If you do, then be sure to seal the holes later when you remove the hitch. If you do not seal them, deadly carbon monoxide (CO) from your exhaust can get into your vehicle. See Engine Exhaust. Dirt and water can, too.
You should always attach chains between your vehicle and your trailer. Cross the safety chains under the tongue of the trailer so that the tongue will not drop to the road if it becomes separated from the hitch. Instructions about safety chains may be provided by the hitch manufacturer or by the trailer manufacturer. Follow the manufacturer's recommendation for attaching safety chains and do not attach them to the bumper. Always leave just enough slack so you can turn with your rig. And, never allow safety chains to drag on the ground.
Because you have anti-lock brakes, do not try to tap into your vehicle's hydraulic brake system. If you do, both brake systems will not work well, or at all. If you tow more than 1,000 lbs. (450 kg), use trailer brakes. Be sure to follow the instructions that come with the trailer or from the brake manufacturer.
Be sure to read and follow the instructions for the trailer brakes so you will be able to maintain them properly.
Driving with a Trailer
Towing a trailer requires a certain amount of experience. Before setting out for the open road, you will want to get to know your rig. Acquaint yourself with the feel of handling and braking with the added weight of the trailer. And always keep in mind that the vehicle you are driving is now a good deal longer and not nearly as responsive as your vehicle is by itself.
Before you start, check the trailer hitch and platform (and attachments), safety chains, electrical connector, lamps, tires and mirror adjustment. If the trailer has electric brakes, start your vehicle and trailer moving and then apply the trailer brake controller by hand to be sure the brakes are working. This lets you check your electrical connection at the same time.
During your trip, check occasionally to be sure that the load is secure, and that the lamps and any trailer brakes are still working.
Stay at least twice as far behind the vehicle ahead as you would when driving your vehicle without a trailer. This can help you avoid situations that require heavy braking and sudden turns.
You will need more passing distance up ahead when you are towing a trailer. And, because you are a good deal longer, you will need to go much farther beyond the passed vehicle before you can return to your lane.
Hold the bottom of the steering wheel with one hand. Then, to move the trailer to the left, just move that hand to the left. To move the trailer to the right, move your hand to the right. Always back up slowly and, if possible, have someone guide you.
Notice: Making very sharp turns while trailering could cause the trailer to come in contact with the vehicle. The vehicle could be damaged. Avoid making very sharp turns while trailering.
When you are turning with a trailer, make wider turns than normal. Do this so your trailer will not strike soft shoulders, curbs, road signs, trees or other objects. Avoid jerky or sudden maneuvers. Signal well in advance.
Turn Signals When Towing a Trailer
When you tow a trailer, your vehicle may need a different turn signal flasher and/or extra wiring. Check with your dealer. The arrows on your instrument panel will flash whenever you signal a turn or lane change. Properly hooked up, the trailer lamps will also flash, telling other drivers you are about to turn, change lanes or stop.
When towing a trailer, the arrows on your instrument panel will flash for turns even if the bulbs on the trailer are burned out. Thus, you may think drivers behind you are seeing your signal when they are not. It is important to check occasionally to be sure the trailer bulbs are still working.
Driving on Grades
Reduce speed and shift to a lower gear before you start down a long or steep downgrade. If you do not shift down, you might have to use your brakes so much that they would get hot and no longer work well.
On long uphill grades, reduce speed to 45 to 50 mph (70 to 90 km/h) and avoid prolonged use of SECOND (2) gear and engine speeds above 3800 rpm.
Climbing grades steeper than four percent at temperatures above 90 F (32 C) with a loaded vehicle and trailer is not recommended. The cooling system may temporarily overheat. See Engine Overheating.
Parking on Hills
Caution: Parking the vehicle on a hill with the trailer attached can be dangerous. If something goes wrong, the rig could start to move. People can be injured, and both the vehicle and the trailer can be damaged. When possible, always park the rig on a flat surface.
But if you ever have to park your rig on a hill, here is how to do it:
Apply your regular brakes, but do not shift into PARK (P).
Have someone place chocks behind the trailer wheels.
When the wheel chocks are in place, release the regular brakes until the chocks absorb the load.
Reapply the regular brakes. Then shift into PARK (P) firmly and apply your parking brake.
Release the regular brakes.
When You Are Ready to Leave After Parking on a Hill
Apply your regular brakes and hold the pedal down while you:
" start your engine
" shift into a gear, and
" make sure the parking brake has released.
Let up on the brake pedal.
Drive slowly until the trailer is clear of the chocks.
Stop and have someone pick up and store the chocks.
Maintenance When Trailer Towing
Your vehicle will need service more often when you are pulling a trailer. See the Maintenance Schedule for more on this. Things that are especially important in trailer operation are automatic transaxle fluid (do not overfill), engine oil, drive belt, cooling system and brake system. Each of these is covered in this manual, and the Index will help you find them quickly. If you are trailering, it is a good idea to review this information before you start your trip.
Check periodically to see that all hitch nuts and bolts are tight.
Engine Cooling When Trailer Towing
Your cooling system may temporarily overheat during severe operating conditions. See Engine Overheating.
Steps for Determining Correct Load Limit
Locate the statement "The combined weight of occupants and cargo should never exceed XXX pounds" on your vehicle placard.
Determine the combined weight of the driver and passengers that will be riding in your vehicle.
Subtract the combined weight of the driver and passengers from XXX kilograms or XXX pounds.
The resulting figure equals the available amount of cargo and luggage load capacity. For example, if the "XXX" amount equals 1400 lbs and there will be five 150 lb passengers in your vehicle, the amount of available cargo and luggage load capacity is 650 lbs (1400 - 750 (5 x 150) = 650 lbs).
Determine the combined weight of luggage and cargo being loaded on the vehicle. That weight may not safely exceed the available cargo and luggage load capacity calculated in Step 4.
If your vehicle will be towing a trailer, the load from your trailer will be transferred to your vehicle. Consult this manual to determine how this reduces the available cargo and luggage load capacity of your vehicle.
If your vehicle can tow a trailer, see Towing a Trailer for important information on towing a trailer, towing safety rules and trailering tips.
Vehicle Capacity Weight for Example 1 =
1,000 lbs (453 kg)
Subtract Occupant Weight @ 150 lbs (68 kg) Ã 2 =
300 lbs (136 kg)
Available Occupant and Cargo Weight =
700 lbs (317 kg)
Vehicle Capacity Weight for Example 2 =
1,000 lbs (453 kg)
Subtract Occupant Weight @ 150 lbs (68 kg) Ã 5 =
750 lbs (340 kg)
Available Cargo Weight =
250 lbs (113 kg)
Vehicle Capacity Weight for Example 3=
1,000 lbs (453 kg)
Subtract Occupant Weight @ 200 lbs (91 kg) Ã 5 =
1000 lbs (453 kg)
Available Cargo Weight =
0 lbs (0 kg)
Refer to your vehicle's tire and loading information label for specific information about your vehicle's capacity weight and seating positions. The combined weight of the driver, passengers and cargo should never exceed your vehicle's capacity weight.
The other label is the Certification label, found on the rear edge of the driver's door. It tells you the gross weight capacity of your vehicle, called the Gross Vehicle Weight Rating (GVWR). The GVWR includes the weight of the vehicle, all occupants, fuel and cargo. Never exceed the GVWR for your vehicle or the Gross Axle Weight Rating (GAWR) for either the front or rear axle.
If you do have a heavy load, you should spread it out. Do not carry more than 203 lbs (92 kg) in the trunk.
Caution : Do not load the vehicle any heavier than the Gross Vehicle Weight Rating (GVWR), or either the maximum front or rear Gross Axle Weight Rating (GAWR). If you do, parts on the vehicle can break, and it can change the way the vehicle handles. These could cause you to lose control and crash. Also, overloading can shorten the life of the vehicle.
Notice : Overloading the vehicle may cause damage. Repairs would not be covered by the vehicle warranty. Do not overload the vehicle.
If you put things inside your vehicle - like suitcases, tools, packages or anything else - they will go as fast as the vehicle goes. If you have to stop or turn quickly, or if there is a crash, they will keep going.
Caution: Things you put inside your vehicle can strike and injure people in a sudden stop or turn, or in a crash.
" Put things in the trunk of your vehicle. In a trunk, put them as far forward as you can. Try to spread the weight evenly.
" Never stack heavier things, like suitcases, inside the vehicle so that some of them are above the tops of the seats.
" Do not leave an unsecured child restraint in your vehicle.
" When you carry something inside the vehicle, secure it whenever you can.
Automatic Level Control
This feature keeps the rear of your vehicle level as the load changes. It is automatic - you do not need to adjust anything.
