Reducing Speed While Using Cruise
Control
There are two ways to reduce your speed while using
cruise control:
PressTat the end of the lever until the lower
speed desired is reached, then release it.
To slow down in very small amounts, briey
press
T. Each time this is done, the vehicle
goes about 1 mph (1.6 km/h) slower.
Passing Another Vehicle While Using
Cruise Control
Use the accelerator pedal to increase your vehicle
speed. When you take your foot off the pedal, the
vehicle slows down to the cruise control speed you
set earlier.
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’s speed. When
going downhill, you might have to brake to keep the
vehicle’s speed down. Applying the brake will turn off the
cruise control. If you need to apply the brake due to the
grade of the downhill slope, you might not want to attempt
to use the cruise control feature.
Ending Cruise Control
There are three ways to end cruise control.
Step lightly on the brake pedal. This will end the
current cruise control session.
Move the cruise control switch to9to turn off the
system completely.

{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.
Adaptive Cruise Control automatically slows your vehicle
down when approaching a slower moving vehicle. It then
adjusts your speed to follow the vehicle in front at the
selected following distance. Your 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
come on. It 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.

The exterior lamp control is located in the middle of the
turn signal/multifunction lever.
O(Exterior Lamp Control):Turn the control with this
symbol on it to operate the exterior lamps.
The exterior lamp control has four positions:
O(Off):Turns off all lamps and automatic lighting
features, including Daytime Running Lamps (DRL) and
IntelliBeam™.
This is a momentary switch that springs back to the
AUTO position when released. An AUTOMATIC LIGHTS
ON message appears on the DIC when automatic lights
are enabled or an AUTOMATIC LIGHTS OFF message
appears on the DIC when the automatic lights are
disabled.AUTO (Automatic):Turns the exterior lamps on and
off automatically depending upon how much light is
outside of the vehicle.

;(Parking Lamps):Turns on the parking lamps
together with the following:
Sidemarker Lamps
Taillamps
License Plate Lamps
Instrument Panel Lights
5(Headlamps):Turns on the headlamps, together
with the previously listed lamps and lights.
IntelliBeam™ Intelligent High-Beam
Headlamp Control System
For vehicles with IntelliBeam, read this entire section
before using this feature.
IntelliBeam is an enhancement to the vehicle’s
headlamp system. It uses a light sensor located on
the back of the rearview mirror to turn the high-beam
headlamps on and off depending on approaching traffic.
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
AUTO3(IntelliBeam On/Off):Press and release
the IntelliBeam button on the inside rear view mirror.
The indicator on the mirror turns on. Once the system
has been turned on, it remains on each time the vehicle
is started. Additionally, the IntelliBeam system must be
enabled.
To enable the System, turn the exterior lamp control
to AUTO, with the turn signal/multifunction lever in its
starting position. The High-Beam On Light appears on
the instrument panel cluster when the high-beams are on.
SeeHighbeam On Light on page 3-70. The vehicle has
variable intensity high-beams. The high-beam indicator
on the instrument panel cluster comes on as soon as the
high-beams start to come on, and remains on until the
high-beams have completely turned off. Vehicles with
IntelliBeam quickly turn off the high-beams if the system
detects the sudden presence of vehicle lights ahead.
3-33

Driving with IntelliBeam
IntelliBeam only activates the high-beams when driving
over 20 mph (32 km/h).
The high-beam headlamps remain on, under the control
of IntelliBeam, until any of the following situations occur:
The system detects an approaching vehicle’s
headlamps.
The system detects a preceding vehicle’s taillamps.
The outside light is bright enough that high-beam
headlamps are not required.
The high-beam headlamps are manually turned on
or you use the ash-to-pass feature. SeeHeadlamp
High/Low-Beam Changer on page 3-9and
Flash-to-Pass on page 3-13.
When either of these conditions occur, the IntelliBeam
feature is temporarily disabled until the high-beam
stalk is returned to its starting position. If either of
these conditions occur and IntelliBeam already has
the high-beam headlamps on, the feature is disabled
and the light in the mirror turns off.
The exterior lamp control is turned to any setting
except AUTO.
When this occurs, IntelliBeam is disabled until the
control is turned back to the AUTO position and the
AUTOMATIC LIGHTS ON message displays on
the DIC.
The IntelliBeam system is turned off at the inside
rearview mirror.
The vehicle’s speed drops below 15 mph (24 km/h).
IntelliBeam may not turn off the high-beams if the
system cannot detect other vehicle’s lamps because
of any of the following:
The others vehicle’s lamp(s) are missing, damaged,
obstructed from view, or otherwise undetected.
The other vehicle’s lamp(s) are covered with dirt,
snow and/or road spray.
The other vehicle’s lamp(s) cannot be detected due
to dense exhaust, smoke, fog, snow, road spray,
mist, or other airborne obstructions.
Your vehicle’s windshield is dirty, cracked, or
obstructed by something that blocks the view of
the IntelliBeam light sensor.
Your vehicle’s windshield is covered with ice, dirt,
haze, or other obstructions.
Your vehicle is loaded such that the front end of
the vehicle points upward, causing the IntelliBeam
sensor to aim high and not detect headlamps
and taillamps.
You are driving on winding or hilly roads.
You might need to manually disable or cancel the
high-beam headlamps by turning the low-beam
headlamps on, if any of the above conditions exist.

Disabling and Resetting IntelliBeam at the
Rearview Mirror
IntelliBeam can be disabled and reset to the original
factory setting by using the controls on the inside
rearview mirror.
AUTO
3(IntelliBeam On/Off):To disable the
system, press this button on the inside rearview mirror.
The IntelliBeam indicator turns off and does not come
back on until the IntelliBeam button is pressed again.
When IntelliBeam has turned on the high-beams, pull or
push the high-beam stalk. This disables IntelliBeam and
the IntelliBeam indicator on the rearview mirror turns off.
To re-enable IntelliBeam, press the IntelliBeam button on
the mirror.
A different sensitivity setting is available for dealer
diagnostics. This is done by pushing and holding this
button for 20 seconds until the light ashes three times.
