190 DRIVING AND OPERATING
Drive Systems
All-Wheel Drive
Vehicles with this feature can operate
in All-Wheel Drive (AWD) Mode. See
Driver Mode Control0195.
Press MODE to activate AWD. AWD is
active in AWD, Sport, and Off-Road
Modes.
The AWD system delivers power to all
four wheels and the system adjusts as
needed to improve traction. The AWD Mode will stay selected
until the mode is changed. If the
vehicle is placed in Sport Mode, see
Driver Mode Control
0195.
Sport Mode and Off-Road Mode are
canceled with each ignition cycle. See
Driver Mode Control 0195.
When operated in Tour Mode, the
vehicle will deliver power to the front
wheels only and may provide better
fuel economy.
If Tour Mode is selected see Driver
Mode Control 0195.
Brakes
Electric Brake Boost
Vehicles equipped with electric brake
boost have hydraulic brake circuits
that are electronically controlled when
the brake pedal is applied during
normal operation. The system
performs routine tests and turns off
within a few minutes after the vehicle
is shutdown. Noise may be heard
during this time. If the brake pedal is
pressed during the tests or when the
electric brake boost system is off, a
noticeable change in pedal force and
travel may be felt. This is normal.
Antilock Brake
System (ABS)
The Antilock Brake System (ABS)
helps prevent a braking skid and
maintain steering while braking hard.
ABS performs a system check when
the vehicle is first driven.
A momentary motor or clicking noise
may be heard while this test is going
on, and the brake pedal may move
slightly. This is normal.

DRIVING AND OPERATING 191
If there is a problem with ABS, this
warning light stays on. SeeAntilock
Brake System (ABS) Warning Light
0 118.
ABS does not change the time needed
to get a foot on the brake pedal and
does not always decrease stopping
distance. If you get too close to the
vehicle ahead, there will not be
enough time to apply the brakes if
that vehicle suddenly slows or stops.
Always leave enough room ahead to
stop, even with ABS.
Using ABS
Do not pump the brakes. Just hold the
brake pedal down firmly. Hearing or
feeling ABS operate is normal.
Braking in Emergencies
ABS allows steering and braking at the
same time. In many emergencies,
steering can help even more than
braking.
Electric Parking Brake
The vehicle has an Electric Parking
Brake (EPB). The EPB can always be
activated, even if the ignition is off. To
prevent draining the battery, avoid
repeated cycles of the EPB system
when the engine is not running. The system has a
Y,f, or PARK
Electric Parking Brake light, and a
8
Service Parking Brake light. See
Electric Parking Brake Light 0118 and
Service Electric Parking Brake Light
0 118.
Before leaving the vehicle, check for
the
Y,f, or PARK light to ensure
that the parking brake is applied.
EPB Apply
To apply the EPB:
1. Be sure the vehicle is at a complete stop.
2. Press the EPB switch momentarily.
The
Y,f, or PARK light will flash
and then stay on once the EPB is fully
applied. If the
Y,f, or PARK light
flashes continuously, then the EPB is
only partially applied or there is a
problem with the EPB. A DIC message
will display. Release the EPB and try
to apply it again. If the light does not
come on, or keeps flashing, have the
vehicle serviced. Do not drive the

192 DRIVING AND OPERATING
vehicle if theY,f, or PARK light is
flashing. See your dealer. See Electric
Parking Brake Light 0118.
If the
8light is on, press the EPB
switch and hold it. Continue to hold
the switch until the
Y,f, or PARK
light remains on. If the
8light
remains on, see your dealer.
If the EPB is applied while the vehicle
is moving, the vehicle will decelerate
as long as the switch is pressed. If the
switch is pressed until the vehicle
comes to a stop, the EPB will remain
applied.
The vehicle may automatically apply
the EPB in some situations when the
vehicle is not moving. This may occur
when shifting to P (Park) on a hill or
with a cold transmission. This is
normal, and is done to periodically
check the correct operation of the EPB
system.
If the EPB fails to apply, block the rear
wheels to prevent vehicle movement.
EPB Release
To release the EPB: 1. Turn the ignition on or to ACC/
ACCESSORY.
2. Apply and hold the brake pedal.
3. Press the EPB switch momentarily.
The EPB is released when the
Y,f,
or PARK light is off.
If the
8light is on, release the EPB by
pressing and holding the EPB switch.
Continue to hold the switch until the
Y,f, or PARK light is off. If either
light stays on after release is
attempted, see your dealer.
Caution
Driving with the parking brake on
can overheat the brake system and
cause premature wear or damage to
brake system parts. Make sure that
the parking brake is fully released
and the brake warning light is off
before driving.
Automatic EPB Release
The EPB will automatically release if
the vehicle is running, placed into
gear, and an attempt is made to drive
away. Avoid rapid acceleration when
the EPB is applied, to preserve parking
brake lining life.
If parking on a hill, or if the vehicle is
pulling a trailer, see Driving
Characteristics and Towing Tips 0234.
Brake Assist
Brake Assist detects rapid brake pedal
applications due to emergency braking
situations and provides additional
braking to activate the Antilock Brake
System (ABS) if the brake pedal is not
pushed hard enough to activate ABS
normally. Minor noise, brake pedal
pulsation, and/or pedal movement
during this time may occur. Continue
to apply the brake pedal as the driving
situation dictates. Brake Assist
disengages when the brake pedal is
released.

DRIVING AND OPERATING 237
2. Have someone place chocksunder the trailer wheels.
3. When the wheel chocks are in place, gradually release the brake
pedal to allow the chocks to
absorb the load of the trailer.
4. Reapply the brake pedal. Then apply the parking brake and shift
into P (Park).
5. Release the brake pedal.
Leaving After Parking on a Hill
1. Apply and hold the brake pedal. .Start the engine.
. Shift into a gear.
. Release the parking brake.
2. Let up on the brake pedal.
3. Drive slowly until the trailer is clear of the chocks.
4. Stop and have someone pick up and store the chocks.
