DRIVING AND OPERATING 211
The transmission does not operate
when the vehicle is off.
If the vehicle is in ACC/ACCESSORY,
the transmission can be shifted into
P (Park).
If the vehicle is turned off while at a
relatively high vehicle speed, the
transmission will automatically shift
to N (Neutral). Once the vehicle is
stopped, P (Park) is automatically
selected.
P :This position locks the drive
wheels. Use P (Park) when starting the
engine because the vehicle cannot
move easily.
{Warning
It is dangerous to get out of the
vehicle if the transmission is not in
P (Park) with the parking brake set.
The vehicle can roll.
Do not leave the vehicle when the
engine is running. If the engine has
been left running, the vehicle can
move suddenly. You or others could
be injured. To be sure the vehicle
will not move, even when on fairly
level ground, always set the parking
brake and place the transmission
into P (Park). See Shifting Into Park
0 206, Driving Characteristics and
Towing Tips 0281 and
Electric Parking Brake 0218.
This vehicle is equipped with an
electronic controlled transmission.
The shift lock release button is
designed to prevent inadvertent
shifting out of P (Park) unless the
ignition is on, the brake pedal is
applied, and the shift lock release
button is pressed.
When the vehicle is stopped, press
ENGINE START/STOP to turn off the
vehicle. The transmission will shift to
P (Park) automatically, unless the
vehicle is in N (Neutral). See “Car
Wash Mode ”later in this section.
The vehicle will not shift into P (Park)
if it is moving too fast. Stop the
vehicle and shift into P (Park).

Service Shift Lever Message
If the message SERVICE SHIFTER SEE
OWNER’S MANUAL appears in the
Driver Information Center (DIC), the
shift lever needs service. Have the
vehicle serviced as soon as possible.
If the vehicle is automatically shifting
into P (Park), check to see if the
P (Park) button on top of the shift
lever is stuck. To operate the vehicle,
hold the shift lever in the desired gear,
R (Reverse) or D (Drive), until vehicle
speed exceeds 15 km/h (10 mph), then
release the shift lever.
R : Use this gear to back up.
If the vehicle is shifted from either
R (Reverse) to D (Drive), or D (Drive)
or M (Manual Mode) to R (Reverse)
while the speed is too high, the
vehicle will shift to N (Neutral).
Reduce the vehicle speed and try the
shift again. To shift into R (Reverse):
1. Bring the vehicle to a complete stop.
2. Press and hold shift lock release button on the side of the shift
lever.
3. From the center position, move the shift lever forward through
the first detent to the end of
travel. R is illuminated in red.
4. After releasing the shift lever, it will return to the center position.
To shift out of R (Reverse):
1. Bring the vehicle to a complete stop.
2. Shift to the desired gear.
3. After releasing the shift lever, it will return to the center position.
At low vehicle speeds, R (Reverse) can
be used to rock the vehicle back and
forth to get out of snow, ice, or sand
without damaging the transmission.
See If the Vehicle Is Stuck 0196. N :
In this position, the engine does
not connect with the wheels. To
restart the engine when the vehicle is
already moving, use N (Neutral) only.
{Warning
Shifting into a drive gear while the
engine is running at high speed is
dangerous. Unless your foot is
firmly on the brake pedal, the
vehicle could move very rapidly.
You could lose control and hit
people or objects. Do not shift into
a drive gear while the engine is
running at high speed.
Caution
Shifting out of P (Park) or
N (Neutral) with the engine running
at high speed may damage the
transmission. The repairs would not
be covered by the vehicle warranty.
Be sure the engine is not running at
high speed when shifting the
vehicle.

DRIVING AND OPERATING 217
Brakes
Antilock Brake
System (ABS)
This vehicle has an Antilock Brake
System (ABS), an advanced electronic
braking system that helps prevent a
braking skid.
When the vehicle begins to drive
away, ABS checks itself. A momentary
motor or clicking noise may be heard
while this test is going on, and it may
even be noticed that the brake pedal
moves a little. This is normal.
If there is a problem with ABS, this
warning light stays on. SeeAntilock
Brake System (ABS) Warning Light
0 143. If driving safely on a wet road and it
becomes necessary to slam on the
brakes and continue braking to avoid
a sudden obstacle, a computer senses
the wheels are slowing down. If one of
the wheels is about to stop rolling, the
computer will separately work the
brakes at each wheel.
ABS can change the brake pressure to
each wheel, as required, faster than
any driver could. This can help you
steer around the obstacle while
braking hard.
As the brakes are applied, the
computer keeps receiving updates on
wheel speed and controls braking
pressure accordingly.
Remember: ABS does not change the
time needed to get a foot up to the
brake pedal or always decrease
stopping distance. If you get too close
to the vehicle in front of you, there
will not be enough time to apply the
brakes if that vehicle suddenly slows
or stops. Always leave enough room
up ahead to stop, even with ABS.
Using ABS
Do not pump the brakes. Just hold the
brake pedal down firmly and let ABS
work. You may hear the ABS pump or
motor operating and feel the brake
pedal pulsate. This is normal.
When ABS is active, it may be an
indication that road surfaces are
slippery. Braking sooner may be
required for driving conditions.
If equipped with electric brake boost,
the TCS/StabiliTrak/ESC light will
flash when ABS is active.
Braking in Emergencies
ABS allows you to steer and brake at
the same time. In many emergencies,
steering can help more than even the
very best braking.

218 DRIVING AND OPERATING
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
Yor PARK
Electric Parking Brake light, and a
8
Service Parking Brake light. See
Electric Parking Brake Light 0143 and
Service Electric Parking Brake Light
0 143. Before leaving the vehicle, check for
the
Yor 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
Yor PARK light will flash and
then stay on once the EPB is fully
applied. If the
Yor 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
vehicle if the
Yor PARK light is
flashing. See your dealer. See Electric
Parking Brake Light 0143.
If the
8light is on, press the EPB
switch and hold it. Continue to
hold the switch until the
Yor 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 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
Yor
PARK light is off.
