Reducing Speed While Using Cruise
Control
To reduce your speed while using cruise control:
Press and hold the SET– button on the
steering wheel until the desired lower speed is
reached, then release it.
To slow down in very small amounts, press
the SET– button on the steering wheel
briey. Each time you do this, the vehicle will
go about 1 mph (1.6 km/h) slower.
Passing Another Vehicle While Using
Cruise Control
Use the accelerator pedal to increase your speed.
When you take your foot off the pedal, your
vehicle will slow down to the previous set cruise
speed.
Using Cruise Control on Hills
How well your cruise control will work on hills
depends upon your speed, load, and the
steepness of the hills. When going up steep hills,
you may have to step on the accelerator pedal
to maintain the vehicle’s speed. When going
downhill, you may have to brake or shift to a lower
gear to keep the vehicle’s speed down. Of
course, applying the brake takes you out of cruise
control. Many drivers nd this to be too much
trouble and do not use cruise control on steep hills.
Ending Cruise Control
There are three ways to end cruise control:
Step lightly on the brake pedal.
Press the cancel button on the steering wheel.
Press the On/Off button on the steering
wheel.
Erasing Speed Memory
When you turn off the cruise control or the
ignition, the cruise control set speed memory is
erased.

How the System Works when Backing
If the shift lever is in REVERSE (R), URPA detects
objects close to the rear bumper. The rst time an
object is detected a single beep will sound. If an
object is detected at a REVERSE (R) speed
between 0 mph (0 km/h) and 5 mph (8 km/h), the
following describes what will occur based on your
distance to a detected object located behind the
vehicle:
At distances between 40 inches (1 m) and
8 ft (2.5 m), a single amber light will come on.
At distances between 23 inches (0.6 m) and
40 inches (1 m), both amber lights will be on.
At distances between 12 inches (0.3 m) and
23 inches (0.6 m), all three lights (amber/
amber/red) will be on.
At distances less than 12 inches (0.3 m), a
beeping sound will repeat for a short time and
all three lights (amber/amber/red) will ash.
When the System Does Not Seem to
Work Properly
If the URPA system will not activate due to a
temporary condition, the message PARKING
ASSIST OFF will be displayed on the DIC screen
and a red light will come on the URPA display
when the shift lever is moved into REVERSE (R).
This occurs under the following conditions:
The driver disables the system.
The parking brake pedal is depressed.
A trailer was attached to your vehicle, or a
bicycle or an object was hanging out of
your trunk during your last drive when you
turned off the vehicle. If the attached objects
are removed from your vehicle before the start
of your next drive, the system will return to
normal operation unless an object is detected
when the vehicle is shifted into REVERSE
(R). If this occurs, URPA assumes the object
is still attached, so you will have to wait
until the vehicle is driven forward above
15 mph (25 km/h) before URPA will return to
normal operation.
224

The ultrasonic sensors are not kept clean. So,
be sure to keep your vehicle’s rear bumper
free of mud, dirt, snow, ice, and slush.
For cleaning instructions, seeWashing Your
Vehicle on page 557. If the DIC still displays
the PARKING ASSIST OFF message
after cleaning the bumper and driving forward
at a speed of at least 15 mph (25 km/h),
see your dealer.
Other conditions that may affect system
performance include vibrations from a
jackhammer or the compression of air brakes
on a very large truck or other mechanical
devices that interfere with URPA performance.
When URPA is disabled without driver
action and the driver attempts to turn URPA
back on by pressing the rear park aid
button, the indicator light will ash for
3 seconds and then stay lit to indicate that
URPA is off.
As always, drivers should use care when backing
up a vehicle. Always look behind you, being
sure to check for other vehicles, obstructions and
blind spots.For Driver Information Center messages related to
URPA, seeDIC Warnings and Messages on
page 270.
If the vehicle bumper is damaged, the URPA
system may not work properly. Take the vehicle to
your dealer to repair the system.
Accessory Power Outlet(s)
Accessory power outlets can be used to
connect auxiliary electrical equipment, such as a
cellular telephone or CB radio. The outlet can
accept electrical equipment up to a maximum of
20 amperes.
There are four accessory power outlets. There are
two under the climate controls, one on the back
of the oor console and a additional accessory
power outlet in the rear cargo area on the
passenger side.

Voltmeter Gage
When your engine is not
running, but the ignition
is in RUN, this gage
shows your battery’s
state of charge in
DC volts.
When the engine is running, the gage shows the
condition of the charging system. The charging
system regulates voltage based on the state of the
battery for improved fuel economy and battery
life. The gage may transition from a higher to lower
or a lower to higher reading, 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 at
an idle for an extended period.This condition is normal since the charging system
is not able to provide full power at engine idle.
As engine speeds are increased, this condition
should correct itself as higher engine speeds allow
the charging system to create full power. If
there is a problem with the battery charging
system, this light will come on or the SERVICE
BATTERY CHARGING SYSTEM DIC message will
display. SeeDIC Warnings and Messages on
page 270andCharging System Light on page 248
for more information.
Brake System Warning Light
With the ignition on, the brake system warning
light will come on when you set the parking brake.
If you try to drive with the parking brake engaged,
a chime will sound when the vehicle speed is
greater than 5 mph (8 km/h).
Your vehicle’s hydraulic brake system is divided
into two parts. If one part is not working, the other
part can still work and stop you. For good
braking, though, you need both parts working well.
If the warning light comes on and a chime
sounds there could be a brake problem. Have
your brake system inspected right away.
249

This light may also come on due to low brake
uid. SeeBrakes on page 486for more
information.
This light should come on briey when you turn
the ignition key to RUN. If it does not come
on then, have it xed so it will be ready to warn
you if there is a problem.
{CAUTION:
Your brake system may not be working
properly if the brake system warning light
is on. Driving with the brake system
warning light on can lead to an accident.
If the light is still on after you have pulled
off the road and stopped carefully, have
the vehicle towed for service.
If the light comes on while you are driving, pull off
the road and stop carefully. You may notice
that the pedal is harder to push or 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 417.

Anti-Lock Brake System Warning
Light
With the Anti-Lock Brake
System (ABS), this
light will come on when
you start your engine
and may stay on for
several seconds.
That is normal. If the light does not come on then,
have it xed so it will be ready to warn you if
there is a problem.
If the light stays on, or comes on when you are
driving, your vehicle needs service. A chime
will sound when the light stays on. If the regular
brake system warning light is not on, you still have
brakes, but you do not have ABS.If the regular brake system warning light is also on
you do not have ABS and there is a problem
with your regular brakes. In addition to both lights,
you will also hear a chime sound on the rst
occurrence of a problem and each time the vehicle
is shut off and then restarted. SeeBrake System
Warning Light on page 249.
The ABS warning light should come on briey
when you turn the ignition key to RUN. If the light
does not come on then, have it xed so it will
be ready to warn you if there is a problem.

STABILITRAK OFF
If your vehicle has StabiliTrak®, this message
displays when you turn off StabiliTrak®, or when
the stability control has been automatically
disabled. To limit wheel spin and realize the full
benets of the stability enhancement system, you
should normally leave StabiliTrak
®on. However,
you should turn StabiliTrak®off if your vehicle gets
stuck in sand, mud, ice, or snow and you want
to rock your vehicle to attempt to free it, or if you
are driving in extreme off-road conditions and
require more wheel spin. SeeIf Your Vehicle is
Stuck in Sand, Mud, Ice, or Snow on page 404.To
turn the StabiliTrak
®system on or off, see
StabiliTrak®System on page 363.
There are several conditions that can cause this
message to appear.
One condition is overheating, which could
occur if StabiliTrak®activates continuously
for an extended period of time.
The message also displays if the brake
system warning light is on. SeeBrake System
Warning Light on page 249.
The message could display if the stability
system takes longer than usual to complete its
diagnostic checks due to driving conditions.
The message displays if an engine or vehicle
related problem has been detected and the
vehicle needs service. See your dealer.
The message also displays if the vehicle is
shifted into 4LO.
The message turns off as soon as the conditions
that caused the message to be displayed are
no longer present.
TIGHTEN GAS CAP
This message may display along with the check
engine light on the instrument panel cluster if
the vehicle’s fuel cap is not tightened properly. See
Malfunction Indicator Lamp on page 253.
Reinstall the fuel cap fully. SeeFilling the Tank on
page 451. The diagnostic system can determine
if the fuel cap has been left off or improperly
installed. A loose or missing fuel cap allows fuel to
evaporate into the atmosphere. A few driving
trips with the cap properly installed should turn this
light and message off.
