uuTowing a Trailer uTowing Preparation
Driving
Towing equipment varies by th e size of your trailer, how much load you are towing,
and where you are towing.
■Hitches
The hitch must be of an approved type and properly bolted to the underbody.
■Safety chains
Always use safety chains when you tow a trailer. Leave enough slack to allow the
trailer to turn corners easily, but do not allow the chains to drag on the ground.
■Trailer brakes
Recommended for any trailer with a total weight of 1,000 lbs (450 kg) or more:
There are two common types of trailer bra kes: surge and electric. Surge brakes are
common for boat trailers, since the brakes will get wet. If you choose electric brakes,
be sure they are electronically actuated. Do not attempt to attach trailer brakes to
your vehicle’s hydraulic system, as it wi ll lower braking effectiveness and create a
potential hazard.
■Additional towing equipment
Many states and provinces/territories requ ire special outside mirrors when towing a
trailer. Even if mirrors are not required in your locale, you should install special
mirrors if visibility is restricted in any way.
■Towing Equipment and Accessories1Towing Equipment and Accessories
Make sure that all equipment is properly installed and
maintained, and that it meets federal, state, province/
territory, and lo cal regulations.
Consult your traile r sales or rental agency if any other
items are recommended or required for your towing
situation.
The lighting and wiring of tra ilers can vary by type
and brand. If a connector is required, it should only
be installed by a qua lified technician.

Driving Safely with a Trailer
• Have the trailer properly servic ed and keep it in good condition.
• Make sure that all the weights and load in the vehicle and trailer are within limits.
2Towing Load Limits P. 403
•Securely attach the hitch, safety chains, and other necessary parts to the trailer.
• Securely store all the items in and on the tra iler so that they do not shift while
driving.
• Check if the lights and brakes on the trailer are working properly.
• Check the pressures of the traile r tires, including the spare.
• Drive slower than normal.
• Obey posted speed limits fo r vehicles with trailers.
• Use the
(D position when towing a trailer on level roads.
• 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 redu ce speed. Pull to the side of the road safely to cool
down the engine if necessary.
• Put the transmission into
(S if the transmission shifts frequently.
■Things You Need To Know Before Towing a Trailer
■Towing Speeds and Gears
■Turning and Braking
■Driving in Hilly Terrain

uuWhen Driving uVehicle Stability Assist ® (VSA ®), aka Electronic Stability Control (ESC), System
Driving
Vehicle Stability Assist ® (VSA ®), aka Electronic
Stability Control (ESC), System
VSA ® helps to stabilize the vehicle during cornering if the vehicle turns more or less
than what was intended. It also assists in maintaining traction on slippery surfaces.
It does so by regulating engine output and selectively applying the brakes.
When VSA® activates, you may notice that the
engine does not respond to the accelerator.
You may also notice some noise from the
hydraulic system. You will also see the
indicator blink.
■VSA ® Operation
1 Vehicle Stability Assist ® (VSA ®), aka Electronic Stability Control
(ESC), System
The VSA ® may not function properl y if tire type and
size are mixed. Make sure to use the same size and
type of tire, and the air pressures as specified.
When the VSA ® system indicator comes on and stays
on while driving, there may be a problem with the
system. While this may not interfere with normal
driving, have your vehi cle checked by a dealer
immediately.
VSA ® cannot enhance stability in all driving situations
and does not control the entire braking system. You
still need to drive and corner at speeds appropriate
for the conditions and always leave a sufficient
margin of safety.
The main function of the VSA ® system is generally
known as Electronic Stab ility Control (ESC). The
system also includes a traction control function.

Lightly brakes the front wheel s, as needed, when you turn the steering wheel, and
helps support the vehicle’s stability and performance during cornering.
1 Agile Handling Assist
The agile handling assist cannot enhance stability in
all driving situations. You still need to drive and
corner at speeds appropriate for the conditions and
always leave a sufficient margin of safety.
When the VSA ® system indicator comes on and stays
on while driving, the agil e handling assist does not
activate.
You may hear a sound coming from the engine

uuWhen Driving uSuper Handling-All Wheel DriveTM (SH-AWD ®)*
Driving
Super Handling-Al l Wheel DriveTM (SH-AWD®)*
The system controls and trans fers varying amounts of engine torque to each wheel
in accordance with the driving conditions.
SH-AWD ® helps to enhance driving stability, and lets you handle situations like
slippery surfaces, such as snow, sand, mud, and steep hill, better than when driving
with two wheel drive. Howeve r, the system does not help to enhance braking. Be
precautious about the following:
• It is still your responsibility to drive sa fely when you steer, accelerate, and apply
brakes.
• Leave a sufficient margin when braking on slippery surfaces.1Super Handling-All Wheel DriveTM (SH-AWD ®)*
The SH-AWD ® system may not function properly if
tire type and size are mixed.
Make sure to use the same size and type of tire, and
the air pressures as specified. 2 Tire and Wheel Replacement P. 560
Do not continuously spin the front tires of your
vehicle. Continuously spinning the front tires can
cause damage to the transmission and SH-AWD ®
unit.
If the Super Handling-All Wheel Drive
TM (SH-AWD® )
indicator blinks while driving, it indicates the
differential temperature is too high. If this happens,
pull to the side of the road when it is safe, change the
gear position to
( P, and idle the engine until the
indicator goes out.
