Towing a TrailerTowing PreparationYour vehicle can tow a trailer if you carefully observe the load limits, use the proper
equipment, and follow the towing guidelines. Check the load limits before driving.
■Total trailer weight
Do not exceed the maximum allowable
weight of the trailer, cargo, and everything in
or on it shown in the table.
Towing loads in excess of this can seriously
affect vehicle handling and performance and
can damage the engine and drivetrain.
Each weight limit is calculated based on the following conditions:
• Occupants fill seats from the front of the vehicle to the back
• Each occupant weights 150 lbs (68 kg)
• Each occupant has 15 lbs (7 kg) of cargo in the cargo area
Any additional weight, cargo or accessories reduce the maximum trailer weight and
maximum tongue load.
■
Towing Load Limits
1 Towing Load Limits
Check if all loads are within limits at a public scale.
If a public scale is not available, add the estimated
weight of your cargo load to the weight of your
trailer (as quoted by the manufacturer), and then
measure the tongue load with an appropriate scale or
tongue gauge or estimate it based on cargo
distribution.
Refer to the trailer owner’s manual fo r additional
information.
Break-in Period
Avoid towing a trailer during your vehicle’s first 600
miles (1,000 km).
Never exceed the gross weight ratings.

WARNING
Exceeding any load limit or improperly
loading your vehicle and trailer can cause a
crash in which you can be seriously hurt or
killed.
Check the loading of your vehicle and
trailer carefully before starting to drive.

■To estimate the tongue load
Excessive tongue load reduces front tire traction and steering control. Too little
tongue load can make the trailer unstable and cause it to sway.
You can estimate the tongue load by measuring the trailer hitch height from the
ground in the following steps:
1. Park the vehicle on level ground.
2. Measure the distance between the ground and the bottom of the trailer hitch.
3. Connect the fully loaded trailer to the hitch.
4. Measure the distance between the ground and the bottom of the trailer hitch
again.
5. Subtract the second measurement from the first measurement, then refer to the
following table.
If the difference becomes more than indicated in the table, distribute the load or
remove cargo as needed.If the difference is

Driving
Trailer Stability Assist
*
Helps to stabilize the vehicle and trailer when the trailer severely sways.■How trailer stability assist works
When the vehicle and trailer become unstable while driving, trailer stability assist
determines the cause. If the trailer oscillation is detected as the cause, and the
swaying increases, the system applies the brakes or controls engine output to reduce
vehicle speed.
Both the vehicle and trailer brake lights come on automatically if you brake to
reduce vehicle speed.
1 Trailer Stability Assist
*
Trailer stability assist is not a function that prevents
the vehicle and trai ler from swaying. Avoid high
speeds, abrupt steering, improper trailer load, and
sudden braking to keep the trailer from swaying.
When swayed too severely, the system becomes
ineffective, and you may loose control of your
vehicle, causing the trailer to roll over or get
damaged. 2 Driving Safely with a Trailer P. 320
Trailer towing sway is caused by:•Crosswinds•Improper towbar down load•Excessive Speed
The VSA ® system indicator blinks during the trailer
stability assist operation.
