The system can be disabled through
the Driver Information Center
(DIC). See “Park Assist” under DIC
Operation and Displays (With
DIC Buttons) on page 3-46 orDIC
Operation and Displays (Without
DIC Buttons) on page 3-51 for more
information.
When the System Does Not
Seem to Work Properly
If the URPA system will not activate
due to a temporary condition, the
message PARK ASSIST OFF will be
displayed on the DIC and a red
light will be shown on the rear URPA display when the shift lever is
moved into R (Reverse). This may
occur under the following
conditions:
The driver disables the system.
The parking brake pedal is
depressed.
The ultrasonic sensors are not
clean. Keep the vehicle’s rear
bumper free of mud, dirt,
snow, ice and slush. For cleaning
instructions, see
Washing Your
Vehicle on page 5-84 .
A trailer was attached to the
vehicle, or a bicycle or an
object was hanging out of the
liftgate during the last drive cycle,
the red light may illuminate in
the rear display. Once the
attached object is removed,
URPA will return to normal
operation.
A tow bar is attached to the
vehicle.
The vehicle’s bumper is
damaged. Take the vehicle to
your dealer/retailer to repair
the system.
Other conditions may affect
system performance, such
as vibrations from a jackhammer
or the compression of air
brakes on a very large truck.
If the system is still disabled, after
driving forward at least 15 mph
(25 km/h), take the vehicle to your
dealer/retailer.

Cruise control can be dangerous
on slippery roads. On such roads,
fast changes in tire traction can
cause excessive wheel slip, and

Voltmeter Gage
When the engine is not running, but
the ignition is turned on, this
gage shows the battery’s state of
charge in DC volts.
When the engine is running, this
gage shows the condition of the
charging system. The vehicle’s
charging system regulates voltage
based on the state of charge of the
battery. The voltmeter may uctuate.
This is normal. Readings between
the low and high warning zones
indicate the normal operating range.
Readings in the low warning zone
may occur when a large number of
electrical accessories are operating
in the vehicle and the engine is
left idling for an extended period.If there is a problem with the battery
charging system, a SERVICE
BATTERY CHARGING SYSTEM
message will appear in the
Driver Information Center (DIC)
and/or the charging system light will
come on. SeeDIC Warnings and
Messages on page 3-56and
Charging System Light on page 3-37
for more information.
However, readings in either warning
zone may indicate a possible
problem in the electrical system.
Have the vehicle serviced as soon
as possible.
Brake System Warning
Light
This vehicle’s hydraulic brake
system is divided into two parts.
If one part is not working, the other
part can still work and stop the
vehicle. For good braking both parts
need to be working.If the warning light comes on, there
is a brake problem. Have the
brake system inspected right away.
This light should come on briey
when the ignition key is turned
to ON/RUN. If it does not come on
then, have it xed so it will be
ready to warn if there is a problem.
This light may also come on due
to low brake uid. SeeBrakes
on page 5-25for more information.
When the ignition is on, the
brake system warning light will also
come on when the parking brake
is set. The light will stay on if
the parking brake does not release
fully. If it stays on after the
parking brake is fully released, it
means there is a brake problem.

If the light comes on while driving,
pull off the road and stop carefully.
Make sure the parking brake is
fully released. The pedal may be
harder to push or, the pedal may go
closer to the oor. It may take
longer to stop. If the light is still on,
have the vehicle towed for service.
SeeTowing Your Vehicle on
page 4-20.
{CAUTION
The brake system might not be
working properly if the brake
system warning light is on. Driving
with the brake system warning
light on can lead to a crash. If the
light is still on after the vehicle
has been pulled off the road and
carefully stopped, have the
vehicle towed for service.
Antilock Brake System
(ABS) Warning Light
For vehicles with the Antilock Brake
System (ABS), this light comes
on briey when the engine is started.
That is normal. If the light does
not come on then, have it xed so it
will be ready to warn if there is a
problem.
If the ABS light stays on, turn the
ignition off. If the light comes
on while driving, stop as soon as it
is safely possible and turn the
ignition off. A chime may also sound
when the light comes on steady.
Then start the engine again to reset
the system. If the ABS light stays
on, or comes on again while driving,
the vehicle needs service. If the
regular brake system warning light
is not on, the vehicle still has
brakes, but not antilock brakes.If the regular brake system warning
light is also on, the vehicle does
not have antilock brakes and there
is a problem with the regular
brakes. SeeBrake System Warning
Light on page 3-38.

Center (DIC), seeDIC Warnings and
Messages on page 3-56for all brake
