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.
The cruise control buttons
are located on left side of
the steering wheel.
I(On):Turns on the cruise control system.
+ RES (Resume/Accelerate):Press to make the
vehicle accelerate or resume to a previously set speed.
SET– (Set):Press to set the speed.
[(Cancel):Press to cancel cruise control.
Cruise control will not work if the parking brake is set, or
if the master cylinder brake uid level is low.
If the brakes are applied, the cruise control shuts off.
The cruise light on the instrument panel cluster comes
on after the cruise control has been set to the desired
speed.
1. Press
I.
2. Get up to the desired speed.
3. Press the SET– button located on the steering
wheel and release it.
4. Take your foot off the accelerator.

Resuming a Set Speed
Suppose the cruise control is set at a desired speed
and then the brakes are applied. This shuts off the
cruise control. But it does not need to be reset.
Once the vehicle is traveling approximately 25 mph
(40 km/h) or more, press the +RES (resume/accelerate)
button to return to the desired preset speed. The cruise
light displays again.
The vehicle returns to and stays at the preset speed.
If you press and hold the +RES button, the vehicle
speed increases until the button is released or the brake
is applied. Do not hold in the +RES button, if you do
not want the vehicle speed to increase.
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, then release
the button and the accelerator pedal. The vehicle
now cruises at the higher speed.
Press the +RES button. Hold it there until the
desired speed is reached, and then release
the button. To increase the vehicle speed in very
small amounts, briey press the +RES button
and then release it. Each time this is done, the
vehicle accelerates approximately 1 mph (1.6 km/h).
The accelerate feature only works after the cruise
control speed is set by pressing the SET– button.
Reducing Speed While Using Cruise
Control
There are two ways to reduce the vehicle speed while
using cruise control:
Press the SET– button until the lower speed
desired is reached, then release it.
To slow down in very small amounts, push the
SET– button briey. Each time this is done, the
vehicle slows down approximately 1 mph (1.6 km/h).
3-18

Passing Another Vehicle While Using
Cruise Control
Use the accelerator pedal to increase the vehicle speed.
When you take your foot off the pedal, the vehicle
slows down to the previous cruise control speed.
Using Cruise Control on Hills
How well your 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’s speed.
When going downhill, you might have to brake or shift to
a lower gear to keep the vehicle’s speed down. Applying
the brake or shifting into a lower gear ends cruise control.
If you need to apply the brake or shift to a lower gear due
to the grade of the downhill slope, you might not want to
attempt to use the cruise control feature.
Ending Cruise Control
To turn off the cruise control, step lightly on the brake
pedal, or press the cancel button on the steering wheel.
Erasing Speed Memory
The cruise control set speed memory is erased when
the cruise control or the ignition is turned off.
Adaptive Cruise Control

without having to constantly reset your cruise control.
3-19

{CAUTION:
When the Adaptive Cruise Control radar is blocked
by snow, ice, or dirt, it may not detect a vehicle
ahead. Adaptive Cruise Control may not have time
to slow your vehicle enough to avoid a collision.
Do not use Adaptive Cruise Control when the
radar is blocked by snow, ice, or dirt. Keep your
radar clean. See “Cleaning the System” later in
this section.
ACC automatically slows your vehicle down when
approaching a slower moving vehicle. It then adjusts
your vehicle speed to follow the vehicle in front at the
selected follow distance. Your vehicle speed increases
or decreases to follow the vehicle in front of you, but will
not exceed the set speed. It may apply limited braking,
if necessary. When braking is active, your brake lights will
come on. Braking may feel or sound different than if you
were applying the brakes yourself. This is normal.
Stationary or Very Slow-Moving Objects
{CAUTION:
Adaptive Cruise Control may not detect and
react to stationary or slow-moving vehicles or
other objects ahead of you. You could crash into
an object ahead of you. Do not use Adaptive
Cruise Control when approaching stationary
or slow-moving vehicles or other objects.
{CAUTION:
Adaptive Cruise Control may not detect and react
to stationary or slow-moving vehicles or other
objects ahead of you. Your vehicle may accelerate
toward objects, such as a stopped vehicle that
suddenly appears after the lead vehicle changes
lanes. Your complete attention is always required
while driving and you should be ready to take
action and apply the brakes.

IntelliBeam™ Intelligent High-Beam
Headlamp Control System
For vehicles with this feature, be sure to read this entire
section before using it.
IntelliBeam is an enhancement to the vehicle’s
headlamp system. Using a digital light sensor on
the rearview mirror, this system turns the vehicle’s
high-beam headlamps on and off according to
surrounding traffic conditions.
The IntelliBeam system turns the high-beam headlamps
on when it is dark enough, there is no other traffic
present, and the IntelliBeam system is enabled.
Turning On and Enabling IntelliBeam™
Press and release the IntelliBeam button on the inside
rear view mirror. The IntelliBeam indicator on the mirror
turns on to indicate the system is on. Once the system
has been turned on, it remains on each time the vehicle
is started, but the IntelliBeam system must be enabled.
To enable the IntelliBeam system, turn the exterior lamp
control to AUTO, with the turn signal/multifunction lever in
its neutral position. The High-Beam On Light appears on
the instrument panel cluster when the high-beams are on.
SeeHighbeam On Light on page 3-66.

When the ignition is on, the brake system warning
light also comes 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. 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 4-26.
{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.
If it does not, have the vehicle serviced by your
dealer/retailer. If the system is working normally the
indicator light then goes off.
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. 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 3-56.
