9-34 Driving and Operating
Electric Parking Brake
The vehicle has an Electric Parking
Brake (EPB). The
Yswitch is on
the center stack. The EPB can
always be activated, even if the
vehicle is off. To prevent draining
the 12‐volt battery, avoid repeated
cycles of the EPB system when the
vehicle is off. In case of insufficient electrical
power, the EPB cannot be applied
or released.
Before leaving the vehicle, check
the Electric Parking Brake Light to
ensure the parking brake is applied.
EPB Apply
The EPB can be applied anytime
the vehicle is stopped. The EPB is
applied by momentarily lifting up on
the
Yswitch. Once fully applied,
the Electric Parking Brake Light will
be on. While the brake is being
applied, the Electric Parking Brake
Light will flash until full apply is
reached. If the light does not come
on, or remains flashing, have the
vehicle serviced. Do not drive the
vehicle if the Electric Parking Brake
Light is flashing. See your dealer. If the EPB is applied while the
vehicle is in motion, a chime will
sound, and the DIC message
RELEASE PARKING BRAKE will be
displayed. The vehicle will
decelerate as long as the switch is
held in the up position. Releasing
the
Yswitch during the
deceleration will release the parking
brake. If the
Yswitch is held in
the up position until the vehicle
comes to a stop, the EPB will
remain applied.
If the Electric Parking Brake Light
flashes continuously, the EPB is
only partially applied or released,
or there is a problem with the EPB.
The DIC message SERVICE
PARKING BRAKE will be displayed.
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.

Driving and Operating 9-35
If the Service Electric Parking Brake
Light is on, the EPB has detected a
system problem and is operating
with reduced functionality. To apply
the EPB when this light is on, lift up
on the
Yswitch 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
Yswitch until
the Electric Parking Brake Light
remains on. If the Service Electric
Parking Brake Light is on, see your
dealer.
If the EPB fails to apply, the rear
wheels should be blocked to
prevent vehicle movement.
For maximum EPB force when
parking on a hill, pull the EPB
switch twice.
EPB Release
To release the EPB, place the
vehicle in ON/RUN, apply and hold
the brake pedal, and push down
momentarily on the
Yswitch.
If attempting to release the EPB
without the brake pedal applied, a
chime will sound, and the DIC
message STEP ON BRAKE TO
RELEASE PARK BRAKE will be
displayed. The EPB is released
when the Electric Parking Brake
Light is off.
If the Service Electric Parking Brake
Light is on, the EPB has detected a
system problem, and is operating
with reduced functionality. To
release the EPB when this light is
on, push down on the
Yswitch
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
Y
switch until the Electric Parking
Brake 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
Electric Parking Brake 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.
See Electric Parking Brake Light on
page 5‑22, Service Electric Parking
Brake Light on page 5‑23, and
Brake System Messages on
page 5‑48.

Using Cruise Control on Hills
How well the cruise control works
on hills depends upon the vehicle
speed, load, and the steepness of
the hills. When going up steep hills,
you might have to step on the
accelerator pedal to maintain the
vehicle speed. When going
downhill, you might have to brake or
shift to a lower gear to maintain the
vehicle speed. When the brakes are
applied the cruise control is
disengaged.Ending Cruise Control
There are three ways to end cruise
control:
.Step lightly on the brake pedal;
when cruise control disengages,
the indicator light will not be lit.
.Press*.
.Press1to turn the cruise
control system off completely.
The cruise control cannot be
resumed.
Erasing Speed Memory
The cruise control set speed is
erased from memory by pressing
1
or if the vehicle is turned off.
Object Detection
Systems
Ultrasonic Parking Assist
If available, the Ultrasonic Front and
Rear Parking Assist (UFRPA)
system assists the driver with

UFRPA operates at speeds less
than 8 km/h (5 mph). The sensors
on the front and rear bumper detect
objects up to 1.2 m (4 ft) in front of
the vehicle, 2.5 m (8 ft) behind the
vehicle, and at least 25 cm (10 in)
off the ground.

improperly positioned can
damage the vehicle or the vehicle
may fall and cause you or others
injury. When using a jack to lift the vehicle,
follow the instructions that came
