uuTowing a TraileruTowing Preparation
188Driving
Towing equipment varies by the 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
There are two common types of trailer brakes: 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 will lower braking effectiveness and create a
potential hazard.
■
Additional towing equipment
Many states and provinces/territories require 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.
■
Trailer light
Trailer lights and equipment must comply with federal, state, province/territory, and
local regulations. Check with your local trailer sales or rental agency for the
requirements in the area where you plan to tow.
■
Towing Equipment and Accessories
1Towing Equipment and Accessories
Make sure that all equipment is properly installed and
maintained, and that it meets federal, state, province/
territory, and local regulations.
Consult your trailer sales or rental agency if any other
items are recommended or required for your towing
situation.
The lighting and wiring of trailers can vary by type
and brand. If a connector is required, it should only
be installed by a qualified technician.

•Securely attach the hitch, safety chains, and other necessary parts to the trailer.
•Securely store all the items in and on the trailer 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 trailer tires, including the spare.
•Drive slower than normal.
•Obey posted speed limits for 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.

Driving
Precautions While DrivingAvoid driving in deep water and on flooded roads. This can damage the engine or
cause electrical component failure.
If there is a strong impact with something under the vehicle, stop in a safe location.
Check the underside of the vehicle for damage or any fluid leaks.■

Other Precautions
1Precautions While Driving
NOTICEDo not operate the shift lever while pressing the
accelerator pedal. You could damage the
transmission.
If the ignition switch is turned to ACCESSORY
(q
or
LOCK
(0
while driving, the engine will shut down
and all steering and brake power assist functions will
stop, making it difficult to control the vehicle.
Do not put the shift lever in
(N
, as you will lose
engine braking (and acceleration) performance.
During the first 600 miles (1,000 km) of operation,
avoid sudden acceleration or full throttle operation so
as to not damage the engine or powertrain.
Avoid hard braking for the first 200 miles (300 km).
You should also follow this when the brakes are
replaced.

uuWhen DrivinguVSA® (Vehicle Stability Assist), aka ESC (Electronic Stability Control), System
Driving
VSA® (Vehicle Stability Assist), aka ESC (Electronic Stability Control), SystemVSA® 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
1VSA® (Vehicle Stability Assist), aka ESC (Electronic Stability Control), System
The VSA® 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.
When the VSA® 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 vehicle 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 Stability Control (ESC). The
system also includes a traction control function.

uuBrakinguBrake System
Driving
Your vehicle is equipped with disc brakes at all four wheels. A power assist helps
reduce the effort needed on the brake pedal. The brake assist system increases the
stopping force when you depress the brake pedal hard in an emergency situation.
The anti-lock brake system (ABS) helps you retain steering control when braking very
hard.

Foot Brake
1Foot Brake
Check the brakes after driving through deep water,
or if there is a buildup of road surface water. If
necessary, dry the brakes by lightly depressing the
pedal several times.
If you hear a continuous metallic friction sound when
applying the brakes, the brake pads need to be
replaced. Have the vehicle checked by a dealer.
Constantly using the brake pedal while going down a
long hill builds up heat, which reduces the brake
effectiveness. Apply engine braking by taking your
foot off the accelerator pedal and downshifting to a
lower gear. With manual transmission use a lower
gear for greater engine braking.
Do not rest your foot on the brake pedal while
driving, as it will lightly apply the brakes and cause
them to lose effectiveness over time and reduce pad
life. It will also confuse drivers behind you.

uuBrakinguABS (Anti-lock Brake System)
Driving
ABS (Anti-lock Brake System)Helps prevent the wheels from locking up, and helps you retain steering control by
pumping the brakes rapidly, much faster than you.
The electronic brake distribution (EBD) system, which is part of the ABS, also
balances the front-to-rear braking distribution according to vehicle loading.
You should never pump the brake pedal. Let the ABS work for you by always
keeping firm, steady pressure on the brake pedal. This is sometimes referred to as
“stomp and steer.”■
ABS operation
The brake pedal may pulsate slightly when the ABS is working. Keep holding the
pedal firmly down. On dry pavement, you will need to press on the brake pedal very
hard before the ABS activates. However, you may feel the ABS activate immediately
if you are trying to stop on snow or ice.
When the vehicle speed goes under 6 mph (10 km/h), the ABS stops.
■
ABS
1ABS (Anti-lock Brake System)
NOTICEThe ABS may not function correctly if you use an
incorrect tire type and size.
When the ABS indicator comes on while driving,
there may be a problem with the system.
While normal braking is not affected, there is a
possibility of the ABS not operating. Have the vehicle
checked by a dealer immediately.
The ABS does not reduce the time or distance it takes
to stop the vehicle. It only helps with steering control
during hard braking.
In the following cases, your vehicle may need more
stopping distance than a vehicle without the ABS:•When driving on rough road surfaces, including
when driving on uneven surfaces, such as gravel or
snow.•When tire chains are installed.
You may hear a motor sound coming from the
engine compartment while system checks are being
performed immediately after starting the engine or
while driving. This is normal.
