or wheel components.
• Make sure the hood is securely closed.
u If the hood opens while driving, your front view will be blocked.

■Exterior Checks1Exterior Checks
NOTICE
When doors are frozen s hut, use warm water around
the door edges to melt any ice. Do not try to force
them open, as this can damage the rubber trim
around the doors. When done, wipe dry to avoid
further freezing.
Do not pour warm water into the key cylinder.
You will be unable to insert the key if the water
freezes in the hole.
Heat from the engine and exhaust can ignite
flammable material s left under the hood, causing a
fire. If you’ve parked y our vehicle for an extended
period, inspect and remove any debris that may have
collected, such as dried grass and leaves that have
fallen or have been carried in for use as a nest by a
small animal. Also check under the hood for leftover
flammable materials after you or someone else has
performed maintenance on your vehicle.

Towing a Trailer
Towing Preparation
Your vehicle can tow a trailer if you carefully observe the load limits, use the proper
equipment, and follow the towing guidelin es. 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 17.6 lbs (8 kg) of cargo in the cargo area
Any additional weight, cargo or accessori es reduce the maximum trailer weight and
maximum tongue load.
■Towing Load Limits1 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 estima te it based on cargo
distribution.
Refer to the trailer owner’s manual for additional
information.
Break-in Period
Avoid towing a trailer duri ng your vehicle’s first 600
miles (1,000 km).
Never exceed the gross weight ratings.
Gross weight information 2 Vehicle Specifications P. 676
3WARNING
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.

uuTowing a Trailer uTrailer Stability Assist
Driving
Trailer Stability Assist
Helps to stabilize the vehicle and tra iler when the trailer severely sways.
■How trailer stability assist works
When the vehicle and trailer become unstab le while driving, trailer stability assist
determines the cause. If the trailer oscill ation is detected as the cause, and the
swaying increases, the system applies the brak es 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 trailer 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 lose control of your vehicle,
causing the trailer to roll over or get damaged. 2 Driving Safely with a Trailer P. 463
Trailer towing sway is caused by:
•Crosswinds
•Improper towbar down load
•Excessive Speed
The VSA ® system indicator blinks during the trailer
stability assist operation. 2 VSA ® Operation P. 520

Driving
• Turn more slowly and with a wider turning arc than normal.
• Allow more time and distance for braking.
• Do not brake or turn suddenly.
• Monitor your temperature gauge. If it nears the red (Hot) mark, turn off the
climate control system and reduce speed. Pull to the side of the road safely to cool
down the engine if necessary.
• Change the gear position to
(S position if the transmission shifts frequently.
If the vehicle tires slip when retrieving a boat from the water, keep the transmission
in
(D and do not use the sequential shift mode in (S. This prevents damage to the
transmission.
Towing Your Vehicle
Your vehicle is not designed to be towed behind a motor home. If your vehicle needs
to be towed in an emergency, refe r to the emergency towing information.
