Driving
AWD (All-Wheel Drive) with Intelligent Control System*
Your vehicle is equipped with the AWD wi th intelligent control system. When the
system senses a loss of front wheel tractio n, it automatically transfers some power
to the rear wheels. This allows you to ut ilize all available traction and may increase
mobility.
You still need to exercise the same care when accelerating, steering, and braking
that you would in a two wheel drive vehicle.
If you excessively spin all four wheels and overheat the AWD with intelligent control
system, only the front wheels receive powe r. Stop until the system cools down.
TPMS (Tire Pressure Monitoring System)
Monitors the tire pressure while you are
driving. If your vehicle's tire pressure becomes
significantly low, the low tire pressure/TPMS
indicator comes on and a message appears on
the multi-information display.
1 AWD (All-Wheel Drive) with Intelligent Control System*
NOTICE
Do not continuously spin the front tires of your
vehicle. Continuously spinning the front tires can
cause transmission or re ar differential damage.
The AWD with intelligent control system may not
function properly if tire ty pe 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. 307
1TPMS (Tire Pressure Monitoring System)
Conditions such as low ambient temperature and
altitude change directly affect tire pressure and can
trigger the low tire pressure/TPMS indicator to come
on.
2 If the Low Tire Pressure/TPMS Indicator
Comes On or Blinks P. 338
Tire pressure checked and inflated in:
•Warm weather can beco me under-inflated in
colder weather.
•Cold weather can become over-inflated in warmer
weather.
The low tire pressure/TPMS indicator will not come
on as a result of over inflation.

uuWhen Driving uTire Pressure Monitoring System (TPMS) - Required Federal Explanation
Driving
correct tire pressure, even if un der-inflation has not reached the
level to trigger illumina tion of the TPMS low ti re pressure telltale.
Your vehicle has also been eq uipped with a TPMS malfunction
indicator to indicate when the sy stem is not operating properly.
The TPMS malfunction indicator is combined with the low tire
pressure telltale. When the system detects a malfunction, the
telltale will flash fo r approximately one minute and then remain
continuously illuminated. This sequence will continue upon
subsequent vehicle start-ups as long as the malfunction exists.
When the malfunction indicator is illuminated, the system may
not be able to detect or signal low tire pressure as intended.
TPMS malfunctions may occur for a variety of reasons, including
the installation of replacement or alternate tires or wheels on the
vehicle that prevent the TPMS from functioning properly.
Always check the TPMS malfunction telltale after replacing one or
more tires or wheels on your vehicle to ensure that the
replacement or alternate tires and wheels allow the TPMS to
continue to function properly.

uuBraking uBrake System
258
Driving
Your vehicle is equipped with disc brakes at all four wheels. A vacuum power assist
helps reduce the effort needed on the brake pedal. The brake assist system increases
the stopping force when you depress th e brake pedal hard in an emergency
situation. The anti-lock brake system (ABS ) helps you retain steering control when
braking very hard.
2 Brake Assist System P. 260
2 ABS (Anti-lock Brake System) P. 259
■Foot Brake1Foot 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 me tallic friction sound when
applying the brakes, the brake pads need to be
replaced. Have the vehicle checked by a dealer.
Constantly using the brak e 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 pe dal and downshifting to a
lower gear.
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 conf use drivers behind you.
Your vehicle is equipped with a hydraulic brake
booster that, under certain conditions, such as
braking at high altitudes, supplements the vacuum
power assist. When the hydraulic brake booster
activates, you may hear a motor sound and a slight
vibration in the pedal. This is normal.

259
uuBraking uABS (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 distribu tion (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 pe dal. 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.
■ABS1ABS (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 ti me or distance it takes
to stop the vehicle. It only helps with steering control
during hard braking.
In the following cases, yo ur vehicle may need more
stopping distance than a vehicle without the ABS:
•When driving on rough road surfaces, including
when driving on uneven surf aces, 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.
