Towing a Trailer
Towing Preparation
188Driving
Towing Equipment and Accessories
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
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.

Precautions While Driving
Precautions While Driving
In Rain
Avoid driving in deep water and on flooded roads. This can damage the engine or
cause electrical component failure.
Other Precautions
If there is a strong impact with something under the vehicle, stop in a safe
location. Check the underside of the vehicle for damage any fluid leaks.
Precautions While Driving NOTICE Do not operate the shift lever while pressing
the accelerator pedal. You could damage the
transmission.
If the ignition switch is turned to ACCESSORY
I 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.

VSA
® (Vehicle Stability Assist), aka ESC (Electronic
Stability Control), 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.
VSA
® Operation
VSA
® (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.
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.

Brake System
Parking Brake
Use the parking brake to keep the vehicle stationary when parking.
To a p p l y :
Pull the lever fully up without pressing the
release button.
To r e l e a s e :
1. Pull the lever slightly, and press and hold
the release button.
2. Lower the lever down all the way, then
release the button.
Parking Brake NOTICE Release the parking brake fully before driving. The
rear brakes and axle can be damaged if you drive
with the parking brake applied.If you start driving without fully releasing the
parking brake, a buzzer sounds as a warning, and
"RELEASE PARKING BRAKE" appears on the multi-
information display.
Always apply the parking brake when parking.
To prevent the parking brake from freezing when
the outside temperature is extremely cold, do not
apply it, but do the following: Automatic transmission models Put the shift lever in
P, then use a block or other
wheel chock to stop the wheels from turning.
Manual transmission models Put the shift lever in
R or
1, then use a block or
other wheel chock to stop the wheels from turning.

Driving
Foot Brake
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
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.

Braking
ABS (Anti-lock Brake System)
212Driving
ABS (Anti-lock Brake System)
ABS
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 (Anti-lock Brake System) NOTICE The 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 ABS:
When driving on rough road surfaces, including twhen driving on uneven surfaces, such as gravel
or snow.
When tire chains are installed. tYou 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.
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.
