9-18 Driving and Operating
The transmitter must be in the
vehicle for the system to operate.
If the pushbutton start is not
working, the vehicle may be near a
strong radio antenna signal causing
interference to the keyless access
system. SeeRemote Keyless Entry
(RKE) System Operation on
page 2‑4 for more information.
To shift out of P (Park), the vehicle
must be in ACC/ACCESSORY or
ON/RUN and the brake pedal must
be applied.
Stopping the Engine/OFF (No
Indicator Lights): When the
vehicle is stopped, press the engine
START/STOP button once to turn
the engine off.
If the vehicle is in P (Park), the
ignition will turn off, and Retained
Accessory Power (RAP) will remain
active. See Retained Accessory
Power (RAP) on page 9‑22 for more
information. If the vehicle is not in P (Park),
the ignition will return to ACC/
ACCESSORY and the Driver
Information Center (DIC) will display
a message. See
Transmission
Messages on page 5‑30 for more
information. When the vehicle is
shifted into P (Park), the ignition
system will switch to OFF.
Do not turn the engine off when the
vehicle is moving. This will cause a
loss of power assist in the brake
and steering systems and disable
the airbags.
If the vehicle must be shut off in an
emergency:
1. Brake using a firm and steady pressure. Do not pump the
brakes repeatedly. This may
deplete power assist, requiring
increased brake pedal force.
2. Shift the vehicle to N (Neutral). This can be done while the
vehicle is moving. After shifting
to N (Neutral), firmly apply the
brakes and steer the vehicle to a
safe location. 3. Come to a complete stop, shift
to P (Park), and turn the ignition
to Stopping the Engine/OFF.
On vehicles with an automatic
transmission, the shift lever must
be in P (Park) to turn the ignition
switch to the Stopping the
Engine/OFF position.
4. Set the parking brake. See Parking Brake on page 9‑31.
{WARNING
Turning off the vehicle while
moving may cause loss of power
assist in the brake and steering
systems and disable the airbags.
While driving, only shut the
vehicle off in an emergency.
If the vehicle cannot be pulled over,
and must be shut off while driving,
switch the ignition to ACC/
ACCESSORY.

9-30 Driving and Operating
Brakes
Antilock Brake
System (ABS)
This vehicle has the Antilock Brake
System (ABS), an advanced
electronic braking system that helps
prevent a braking skid.
When the engine is started and the
vehicle begins to drive away, ABS
checks itself. A momentary motor or
clicking noise might be heard while
this test is going on, and it might
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
on page 5‑17. 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 that 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
the driver 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 might hear the ABS
pump or motor operating and feel
the brake pedal pulsate, but this is
normal.
Braking in Emergencies
ABS allows the driver to steer and
brake at the same time. In many
emergencies, steering can help
more than even the very best
braking.

Driving and Operating 9-31
Parking Brake
The vehicle has an Electric Parking
Brake (EPB). The switch for the
EPB is in the center console. The
EPB can always be activated,
even if the ignition is off. To avoid
draining the battery, do not cycle the
EPB too often without the engine
running. The EPB can be left
applied while the vehicle is parked.
The system has a parking brake
status light and a parking brake
warning light. SeeBrake System
Warning Light on page 5‑16. There are also Driver Information Center
(DIC) messages. See
Brake System
Messages on page 5‑25 for more
information. In case of insufficient
electrical power, the EPB cannot be
applied or released.
Before leaving the vehicle, check
the parking brake status light to
ensure the parking brake is applied.
EPB Apply
The EPB can be applied any time
the vehicle is stopped. The EPB is
applied by momentarily lifting up on
the EPB switch. Once fully applied,
the parking brake status light will be
on. While the brake is being applied,
the status light will flash until full
apply is reached. If the light does
not come on, or remains flashing,
you need to have the vehicle
serviced. Do not drive the vehicle if
the parking brake status light is
flashing. See your dealer. See
Brake System Warning Light on
page 5‑16 for more information. If the EPB is applied while the
vehicle is in motion, a chime will
sound, and a DIC message will be
displayed. See
Brake System
Messages on page 5‑25. The
vehicle will decelerate as long as
the switch is held in the up position.
Releasing the EPB switch during
the deceleration will release the
parking brake. If the switch is held
in the up position until the vehicle
comes to a stop, the EPB will
remain applied.
If the parking brake status light
flashes continuously, the EPB is
only partially applied or released,
or there is a problem with the EPB.
A DIC message will be displayed.
See Brake System Messages on
page 5‑25. If this light flashes
continuously, release the EPB, and
attempt to apply it again. If this light
continues to flash, do not drive the
vehicle. See your dealer.
If the parking brake warning light
is on, the EPB has detected an
error in another system and is
operating with reduced functionality.

9-32 Driving and Operating
To apply the EPB when this light is
on, lift up on the EPB switch and
hold it in the up position. Full
application of the parking brake by
the EPB system may take a longer
period of time than normal when
this light is on. Continue to hold the
switch until the parking brake status
light remains on. If the parking
brake warning light is on, see your
dealer.
If the EPB fails to apply, the rear
wheels should be blocked to
prevent vehicle movement.
EPB Release
To release the EPB, place the
ignition in the ON/RUN position,
apply and hold the brake pedal,
and push down momentarily on
the EPB switch. If you attempt to
release the EPB without the brake
pedal applied, a chime will sound,and a DIC message will be
displayed. See
Brake System
Messages on page 5‑25. The EPB
is released when the parking brake
status light is off.
If the parking brake warning light is
on, the EPB has detected an error
in another system and is operating
with reduced functionality. To
release the EPB when this light is
on, push down on the EPB switch
and hold it in the down position.
EPB release may take a longer
period of time than normal when
this light is on. Continue to hold the
switch until the parking brake status
light is off. If the light is on, see your
dealer. Notice:
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.

The vehicle has a vehicle stability
enhancement system called
StabiliTrak. It is an advanced
computer controlled system that
assists with directional control of the
vehicle in difficult driving conditions.
StabiliTrak activates when the
computer senses a difference
between the intended path, and the
direction the vehicle is actually
traveling. StabiliTrak selectively
applies braking pressure at any one
of the vehicle's brakes to help steer
the vehicle in the intended direction.
StabiliTrak is on automatically
whenever the vehicle is started. To
assist with directional control of the
vehicle, the system should always
be left on.
TCS/StabiliTrak Light
When the stability control system
activates,
dflashes on the
instrument panel. This also occurs
when traction control is activated.
A noise may be heard or vibration
may be felt in the brake pedal. This
is normal. Continue to steer the
vehicle in the intended direction.
If there is a problem detected
with StabiliTrak, the appropriate
message will be displayed
on the DIC. See Ride Control
System Messages on page 5‑29.
When a message is displayed

Object Detection
Systems
Ultrasonic Parking Assist
For vehicles with the Ultrasonic
Rear Parking Assist (URPA) system,
it assists the driver with parking
and avoiding objects while in
R (Reverse). URPA operates at
speeds less than 8 km/h (5 mph).
The sensors on the rear bumper
detect objects up to 2.5 m (8 ft)
behind the vehicle, and at least
20 cm (8 in) off the ground.
{WARNING
The URPA system does not
detect children, pedestrians,
bicyclists, animals, or objects
below the bumper or that are too
close or too far from the vehicle.
It is not available at speeds
greater than 8 km/h (5 mph). To
prevent injury, death, or vehicle
(Continued)
WARNING (Continued)
damage, even with URPA, always
check the area around the vehicle
and check all mirrors before
backing.
How the System Works
URPA comes on automatically
when the shift lever is moved into
R (Reverse). A single tone sounds
to indicate the system is working.
URPA operates only at speeds less
than 8 km/h (5 mph).
An obstacle is indicated by audible
beeps. The interval between the
beeps becomes shorter as the
vehicle gets closer to the obstacle.
When the distance is less than
30 cm (12 in), the beeping is a
continuous tone for five seconds.

Vehicle Care 10-17
Brakes
This vehicle has disc brakes. Disc
brake pads have built-in wear
indicators that make a high-pitched
warning sound when the brake pads
are worn and new pads are needed.
The sound can come and go or be
heard all the time the vehicle is
moving, except when applying the
brake pedal firmly.
{WARNING
The brake wear warning sound
means that soon the brakes will
not work well. That could lead to
a crash. When the brake wear
warning sound is heard, have the
vehicle serviced.
Notice: Continuing to drive with
worn-out brake pads could result
in costly brake repair. Some driving conditions or climates
can cause a brake squeal when the
brakes are first applied or lightly
applied. This does not mean
something is wrong with the brakes.
Properly torqued wheel nuts are
necessary to help prevent brake
pulsation. When tires are rotated,
inspect brake pads for wear and
evenly tighten wheel nuts in the
proper sequence to torque
specifications in
Capacities and
Specifications on page 12‑2.
Brake linings should always be
replaced as complete axle sets.
Brake Pedal Travel
See your dealer if the brake pedal
does not return to normal height,
or if there is a rapid increase in
pedal travel. This could be a sign
that brake service might be
required.
Brake Adjustment
Every time the brakes are applied,
with or without the vehicle moving,
the brakes adjust for wear.
Replacing Brake System Parts
The braking system on a vehicle is
complex. Its many parts have to be
of top quality and work well together
if the vehicle is to have really good
braking. The vehicle was designed
and tested with top-quality brake
parts. When parts of the braking
system are replaced, be sure to get
new, approved replacement parts.
If this is not done, the brakes might
not work properly. For example,
installing disc brake pads that are
wrong for the vehicle, can change
the balance between the front and
rear brakes —for the worse. The
braking performance expected can
change in many other ways if the
wrong replacement brake parts are
installed.

10-18 Vehicle Care
Brake Fluid
The brake master cylinder and, on
manual transmission vehicles, the
clutch hydraulic system use the
same reservoir. SeeEngine
Compartment Overview on
page 10‑6 for the location of the
reservoir. The reservoir is filled
with with either DOT 3 or DOT 4
brake fluid as indicated on the
reservoir cap.
There are only two reasons why the
brake fluid level in the reservoir
might go down:
.The brake fluid level goes down
because of normal brake lining
wear. When new linings are
installed, the fluid level goes
back up.
.A fluid leak in the brake/clutch
hydraulic system can also cause
a low fluid level. Have the brake/
clutch hydraulic system fixed,
since a leak means that sooner
or later the brakes will not
work well.
Do not top off the brake/clutch fluid.
Adding fluid does not correct a leak.
If fluid is added when the linings are
worn, there will be too much fluid
when new brake linings are
installed. Add or remove fluid, as
necessary, only when work is done
on the brake/clutch hydraulic
system.
{WARNING
If too much brake fluid is added, it
can spill on the engine and burn,
if the engine is hot enough. You
or others could be burned, and
the vehicle could be damaged.
Add brake fluid only when work
is done on the brake/clutch
hydraulic system.
Checking Brake Fluid
The brake/clutch fluid can be
checked without taking off the cap
by looking at the brake/clutch fluid
reservoir.
The fluid level should be above
MIN. If it is not, have the brake/
clutch hydraulic system checked to
see if there is a leak.
After work is done on the brake/
clutch hydraulic system, make sure
the level is above MIN but not over
the MAX mark.
When the brake/clutch fluid falls to a
low level, the brake warning light
comes on. See Brake System
Warning Light on page 5‑16.
What to Add
If the vehicle has DOT 3 brake fluid,
as indicated on the reservoir cap,
use only new DOT 3 brake fluid
from a sealed container. See
Recommended Fluids and
Lubricants on page 11‑12.
