With cruise control, you can maintain a speed of about
25 mph (40 km/h) or more without keeping your foot
on the accelerator. This can really help on long
trips. Cruise control does not work at speeds below
about 25 mph (40 km/h).
If you apply your brakes, the cruise control will shut off.
{CAUTION:
Cruise control can be dangerous where you
can not drive safely at a steady speed. So, do
not use your cruise control on winding roads
or in heavy traffic.
Cruise control can be dangerous on slippery
roads. On such roads, fast changes in tire
traction can cause needless wheel spinning,
and you could lose control. Do not use cruise
control on slippery roads.
Setting Cruise Control
{CAUTION:
If you leave your cruise control on when you
are not using cruise, you might hit a button
and go into cruise when you do not want to.
You could be startled and even lose control.
Keep the cruise control switch off until you
want to use cruise control.
1. Move the cruise control switch to on.
2. Get up to the speed you want.
3. Press in the set button at the end of the lever and
release it.
4. Take your foot off the accelerator pedal.
The cruise symbol on the
instrument panel will
illuminate when the cruise
control is engaged.

Resuming a Set Speed
Suppose you set your cruise control at a desired speed
and then you apply the brake. This, of course,
disengages the cruise control. But you don’t need to
reset it.
Once you’re going about 25 mph (40 km/h) or more, you
can move the cruise control switch brie y from on to
resume/accelerate.
You’ll go right back up to your chosen speed and stay
there.
If you hold the switch at resume/accelerate the vehicle
will keep going faster until you release the switch or
apply the brake. So unless you want to go faster, don’t
hold the switch at resume/accelerate.
Increasing Speed While Using Cruise
Control
There are two ways to go to a higher speed:
Use the accelerator pedal to get to the higher
speed. Press the set button at the end of the lever,
then release the button and the accelerator
pedal. You’ll now cruise at the higher speed. If the
accelerator pedal is held longer than 60 seconds,
cruise control will turn off.
Move the cruise switch from on to
resume/accelerate. Hold it there until you get up to
the speed you want, and then release the switch.
To increase your speed in very small amounts,
move the switch brie y to resume/accelerate. Each
time you do this, your vehicle will go about
1 mph (1.6 km/h) faster.
Reducing Speed While Using Cruise
Control
Press in the button at the end of the lever until you
reach the lower speed you want, then release it.
To slow down in very small amounts, brie y press
the set button. Each time you do this, you’ll 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 cruise control speed you set earlier.
3-13
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 want to step
on the accelerator pedal to maintain your speed.
When going downhill, you may have to brake or shift to
a lower gear to keep your speed down. Of course,
applying the brake takes you out of cruise control. Many
drivers nd this to be too much trouble and don’t use
cruise control on steep hills.
Ending Cruise Control
There are four ways to turn off the cruise control:
Step lightly on the brake pedal,
move the cruise control switch to off, or
shift the transmission to NEUTRAL (N).
If your vehicle has the Stabilitrak®feature, cruise
control will turn off if road conditions cause
Stabilitrak
®to activate.
If the accelerator pedal is held for 60 seconds or
longer, cruise control will turn off.
Erasing Speed Memory
When you turn off the cruise control or the ignition, your
cruise control set speed memory is erased.
Exterior Lamps
The control on the driver’s side of your instrument panel
operates the exterior lamps.
The exterior lamp control has four positions:
9(Off):Turn the knob to this position and release it
to turn off all exterior lamps including the DRLs. To turn
any lamps back on when in the off mode, turn the
knob to the desired lamp mode. To return to the AUTO
mode, turn the knob to the off position and release
it. The off mode will also cancel and the lamps will return
to the AUTO when the vehicle is turned off. This
mode is not available for vehicles rst sold in Canada.

How the System Works
Unless disabled, the URPA will turn on automatically
when the shift lever is moved into REVERSE (R). When
the system turns on, the three lights on the display
will illuminate for one and a half seconds to let you know
that the system is working. If your vehicle is moving in
REVERSE (R) at a speed greater than 3 mph (5 km/h),
the red light will ash to remind you that the system
does not work at a speed greater than 3 mph (5 km/h).
If an object is detected at a REVERSE (R) speed of
less than 3 mph (5 km/h), one of the following will occur:
A chime will sound the rst time an object is detected
between 20 inches (0.5 m) and 5 feet (1.5 m) away.
Description English Metric
amber light 5 ft. 1.5 m
amber/amber lights 40 in. 1.0 m
amber/amber/red lights &
continuous chime20 in. 0.5 m
amber/amber/red lights
ashing & continuous
chime1 ft 0.3 m
URPA cannot detect objects that are above liftgate level.
In order for the rear sensors to recognize an object, it
must be within detection range behind the vehicle.
When the System Does Not Seem to Work
Properly
The light may ash red when the vehicle is in
REVERSE (R) if the ultrasonic sensors are not kept
clean. So be sure to keep your rear bumper free of mud,
dirt, snow, ice and slush. Other conditions that may
affect system performance include things like the
vibrations from a jackhammer or the compression of air
brakes on a very large truck. If after cleaning the
rear bumper and then driving forward at least
15 mph (25 km/h), the display continues to ash red,
see your dealer.
If a trailer was attached to your vehicle, or a bicycle or
an object was on the back of, or hanging out of your
cargo area during your last drive cycle, the light
may also ash red. The light will continue to ash
whenever in REVERSE (R) until your vehicle is driven
forward at least 15 mph (25 km/h) without any
obstructions behind the vehicle.
For cleaning instructions, seeCleaning the Outside of
Your Vehicle on page 5-108.

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. 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 maximum power.You can only drive for a short time with the reading in
either warning zone. If you must drive, turn off all
unnecessary accessories.
Readings in either warning zone indicate a possible
problem in the electrical system. Have the vehicle
serviced as soon as possible.
Brake System Warning Light
With the ignition on, the brake system warning light will
ash when you set the parking brake. The light will
ash if the parking brake doesn’t release fully. If you try
to drive with the parking brake engaged, a chime will
sound when the vehicle speed is greater than
3 mph (5 km/h).
Your vehicle’s hydraulic brake system is divided into two
parts. If one part isn’t 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.
