There are three messages that may appear on the
Driver Information Center (DIC). They are CLEAN
RADAR, RADAR CRUISE NOT READY and SERVICE
RADAR CRUISE. SeeDIC Warnings and Messages
on page 3-73.
Cleaning the System
The radar can become blocked by snow, ice, or dirt.
If so, you may need to turn off the engine and clean
the lens. See “Cleaning the System” underAdaptive
Cruise Control on page 3-19.
Flash-to-Pass
This feature lets you use the high-beam headlamps to
signal the driver in front of you that you want to pass.
The ash-to-pass feature will only work with the
headlamps on. It does not work with Daytime
Running Lamps (DRL).
Pull and hold the turn signal lever toward you to use.
If the headlamps are on low beam, pulling the turn signal
towards you will ash the high beams.
Windshield Wipers
Turn the band with the wiper symbol on it to control the
windshield wipers.
8(Mist):For a single wiping cycle, hold it on mist
until the wipers start, then release. The wipers stop after
one wipe. For more wipe cycles, hold the band longer.
6(Delay):Use to set the delay time between wipe
cycles. The wiper speed can be set for a long or short
delay between wipes. The closer the band is set to
the top of the lever, the shorter the delay.
6(Low Speed):For steady wiping at low speed.
1(High Speed):For high-speed wiping.
9(Off):Turns the wipers off.
Clear ice and snow from the wiper blades before
using them. If the wipers are frozen to the windshield,
carefully loosen or thaw them. If they become worn
or damaged, replace with new blades or blade inserts.
Heavy snow or ice can overload the wiper motor.
A circuit breaker will stop the motor until it cools.
The vehicle has wiper-activated headlamps. After the
windshield wipers have completed eight wipe cycles
within four minutes, the headlamps automatically turn on.
SeeWiper Activated Headlamps on page 3-32for more
information.

Windshield Washer
{CAUTION:
In freezing weather, do not use your washer until
the windshield is warmed. Otherwise the washer
uid can form ice on the windshield, blocking your
vision.
J(Washer Fluid):Press and release this paddle,
located at the top of the turn signal/multifunction lever,
to spray washer uid on the windshield. The wipers
will clear the windshield and either stop or return to the
preset speed. For more washer cycles, press and hold
the paddle.
_(Heated Washer Fluid):The heated windshield
washer uid system, if the vehicle has this feature,
may be used to help clear ice, snow, tree sap, or bugs
from the windshield. Slide the control on the turn signal/
multifunction lever to this position and then release, to
activate the heated windshield washer uid system.
This activation initiates four heated wash/wipe cycles.
The rst heated wash/wipe cycle may take up to
40 seconds to occur, depending on outside temperature.
After the rst wash/wipe cycle, it may take up to
20 seconds for each of the remaining cycles. The heated
windshield washer uid system may be turned off at any
time by sliding the control on the turn signal/multifunction
lever to this position again.
When the heated windshield washer uid system is
activated under certain outside temperature conditions,
steam may ow out of the washer nozzles for a short
period of time before washer uid is sprayed. This is a
normal condition.
WASHER FLUID LOW ADD FLUID will be displayed on
the Driver Information Center (DIC) when the washer
uid is low. SeeDIC Warnings and Messages on
page 3-73.

ACC uses radar to detect a vehicle directly ahead
in your path, within a distance of 330 ft (100 m), and
operates at speeds above 25 mph (40 km/h). When it
is engaged by the driver, the system can apply limited
braking or acceleration of the vehicle automatically
to maintain a selected follow distance to the vehicle
ahead. Braking is limited to 0.25 g’s (2.45 m/sec2)
of deceleration, which is comparable to moderate
application of the vehicle’s brakes. To disengage ACC,
apply the brake. If no vehicle is in your path, the vehicle
will react like traditional cruise control.
{CAUTION:
Adaptive Cruise Control will not apply hard braking
or bring the vehicle to a complete stop. It will not
respond to stopped vehicles, pedestrians or
animals. When you are approaching a vehicle or
object, Adaptive Cruise Control may not have time
to slow your vehicle enough to avoid a collision.
Your complete attention is always required while
driving and you should be ready to take action
and apply the brakes. For more information,
seeDefensive Driving on page 4-2.
{CAUTION:
On winding roads, Adaptive Cruise Control
may not detect a vehicle ahead. You could
crash into a vehicle ahead of you. Do not use
Adaptive Cruise Control on winding roads.
Adaptive Cruise Control may not have time
to slow your vehicle enough to avoid a crash
when you are driving in conditions where
vehicles may suddenly slow or stop ahead of
you, enter your lane, or cross your vehicle’s
path. If you are driving in these conditions, do
not use Adaptive Cruise Control. The warning
beep and alert symbol may indicate that you
are driving in conditions where Adaptive Cruise
Control should not be used. See “Alerting the
Driver” in this section.
On slippery roads, fast changes in tire traction
can cause needless wheel spinning, and you
could lose control. Do not use cruise control on
slippery roads.
CAUTION: (Continued)
3-20

Engaging ACC With the Set Button
{CAUTION:
If you leave your Adaptive Cruise Control switch
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 Adaptive Cruise Control switch off until
you want to use cruise control.
The set speed is selected by the driver. This is the
speed your vehicle will travel if there is no vehicle
detected in its path.
To set ACC, do the following:
1. Press the
]button.
2. Get up to the speed desired.
3. Press in the SET– button and release it.
4. Take your foot off the accelerator pedal.
Once ACC is set, it may immediately apply the brakes if
it detects a vehicle ahead is too close or moving slower
than your vehicle.The on symbol is located on the display at the top of the
instrument panel to the right of the driver. When the on
symbol is lit on the display, it indicates that ACC is active.
A message on the DIC will also display when ACC is
set. SeeDIC Warnings and Messages on page 3-73.
Keep in mind speed limits, surrounding traffic speeds,
and weather conditions when adjusting your set speed.
If the vehicle is in ACC when the traction control system
begins to limit wheel spin, the ACC will automatically
disengage. SeeTraction Control System (TCS) on
page 4-6andStabiliTrak
®System on page 4-6. When
road conditions allow you to safely use it again, the ACC
can be turned back on.
Increasing Set Speed While Using ACC
There are two ways to increase the set speed:
Use the accelerator to get to the higher speed.
Press the SET– button and then release the
button and the accelerator pedal. The vehicle
will now cruise at the higher speed.
Press the +RES button. Hold it there until the
desired set speed is displayed on the Driver
Information Center (DIC), then release the switch.
To increase the set speed in very small amounts,
move the switch briey to +RES. Each time this is
done, the set speed increases by 1 mph (1 km/h).
3-22

Alerting the Driver
The ACC alert symbol is
located on the display at
the top of the instrument
panel to the right of the
driver.
The alert symbol ashes and a warning beep sounds
when driver action may be required. If ACC is engaged,
the alert symbol will ash when:
ACC cannot apply sufficient braking because you
are approaching a vehicle too rapidly.
The vehicle speed drops below about
20 mph (32 km/h).
A temporary condition prohibits ACC from operating.
SeeDIC Warnings and Messages on page 3-73for
more information.
A malfunction is detected in the system. SeeDIC
Warnings and Messages on page 3-73for more
information.
SeeDefensive Driving on page 4-2.
{CAUTION:
Adaptive Cruise Control has only limited braking
ability to slow your vehicle. In some cases, Adaptive
Cruise Control may not have time to slow your
vehicle enough to avoid a collision. Be ready to
take action and apply the brakes yourself.
SeeDefensive Driving on page 4-2.
Approaching and Following a Vehicle
The vehicle ahead symbol
is located on the top of the
instrument panel to the
right of the driver.
The vehicle ahead symbol only appears when a vehicle
is detected in your path.
If this symbol does not appear, or disappears briey,
ACC will not respond to vehicles you may see ahead.
3-24

Low-Speed Deactivation
If your vehicle speed falls below 20 mph (32 km/h) while
following a vehicle ahead, ACC will begin to disengage.
The Driver Alert symbol will ash and the warning beep
will sound. The driver must take action since ACC will not
slow the vehicle to a stop.
Passing a Vehicle/ACC Override
To increase speed to pass a vehicle, use the
accelerator pedal. While you are doing this, the system
will not automatically apply the brakes. A message will
appear on the DIC. SeeDIC Warnings and Messages
on page 3-73. Once you remove your foot from the
accelerator pedal, ACC will return to normal operation
and be able to apply the brakes, if needed.
{CAUTION:
If you rest your foot on the accelerator pedal,
the system will not automatically apply the brakes.
You could crash into a vehicle ahead of you.
Do not rest your foot on the accelerator pedal
when using Adaptive Cruise Control.
Curves in the Road
{CAUTION:
Due to Adaptive Cruise Control limitations in
curves, it may respond to a vehicle in another
lane, or may not have time to react to a vehicle in
your lane. You could crash into a vehicle ahead
of you, or lose control of your vehicle. Give extra
attention in curves and be ready to use the brakes
if necessary. Select an appropriate speed while
driving in curves.
ACC may operate differently in a sharp curve. It may
reduce your vehicle speed if the curve is too sharp.
3-26

Erasing Set Speed Memory
Press the ACC button or turn the ignition off.
Other Messages
There are three additional messages that may appear
on the DIC. They are SERVICE RADAR CRUISE,
RADAR CRUISE NOT READY and CLEAN RADAR.
These messages will appear to indicate a problem
with the ACC. SeeDIC Warnings and Messages
on page 3-73for more information.
Cleaning the System
The radar can become blocked by snow, ice, or dirt.
If so, you may need to turn off the engine and clean
the lens. Remember, do not use ACC in icy conditions,
or when visibility is low, such as in fog, rain or snow.
The emblem/lens is located in the center of the grille.
To clean the emblem/lens, wipe the surface with a soft
cloth. After cleaning the emblem/lens, try to engage the
ACC. If you are unable to do so, see your dealer/retailer.
Exterior Lamps
The exterior lamps control
is located on the instrument
panel to the left of the
steering wheel.
It controls the following systems:
Headlamps
Taillamps
Parking Lamps
License Plate Lamps
Instrument Panel Lights
Fog Lamps
3-29

The exterior lamps control has four positions:
O(Off):Turns off the exterior lamps except for
Daytime Running Lamps (DRL).
AUTO (Automatic):Automatically turns on the
headlamps at normal brightness, together with the
following:
Parking Lamps
Instrument Panel Lights
IntelliBeam™
;(Parking Lamps):Turns on the parking lamps
together with the following:
Instrument Panel Lights
License Plate Lamps
Taillamps
Side Marker Lamps
The parking brake indicator light comes on and stays
on while the parking lamps are on with the engine
off and the ignition in ACC/ACCESSORY or ON/RUN.
2(Headlamps):Turns on the headlamps together
with the previously listed lamps. A warning chime sounds
if the driver’s door is opened while the ignition switch is off
and the headlamps are on.
#(Fog Lamps):Press the exterior lamps control to
turn on the fog lamps. SeeFog Lamps on page 3-34.
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.
3-30

Headlamps on Reminder
A warning chime will sound if the exterior lamp control
is left on in either the headlamp or parking lamp position
and the driver’s door is opened with the ignition off.
Daytime Running Lamps (DRL)
Daytime Running Lamps (DRL) can make it easier for
others to see the front of your vehicle during the day.
Fully functional daytime running lamps are required
on all vehicles rst sold in Canada.
The DRL system makes the turn signal lamps come on
when the following conditions are met:
It is still daylight and the ignition is on.
The exterior lamp control is in the off position.
The transmission is not in P (Park)
(United States only).
The light sensor is covered or not detecting light.
See “Sensors” underDual Climate Control System
on page 3-40.
When DRL are on, no other exterior lamps such as the
parking lamps, taillamps, etc. will be on when the DRL
are being used. The instrument panel will not be lit
up either.When automatic lighting is on and it is dark enough
outside, the turn signal lamps turn off and normal
low-beam headlamp operation occurs.
When automatic lighting is on and it is bright enough
outside, the regular lamps go off, and the DRL takes over.
If the vehicle is started in a dark garage, the automatic
headlamp system comes on immediately. Once you
leave the garage, it will take approximately one minute
for the automatic headlamp system to change to DRL if
there is light outside. During that delay, the instrument
panel cluster may not be as bright as usual. Make sure
the instrument panel brightness knob is in the full bright
position. SeeInstrument Panel Brightness on page 3-34.
Turning on automatic lighting or the headlamps will
deactivate the DRL. If the parking lamps or the fog lamps
were turned on instead, the DRL will still deactivate.
To idle the vehicle with the DRL off at night, turn off
automatic lighting and shift the transmission into P (Park).
Placing the vehicle in P (Park) disables the DRL. The
DRL will stay off until the vehicle is shifted out of P (Park).
To drive the vehicle with the DRL off, turn off automatic
lighting and manually turn on the parking lamps or
fog lamps, if the vehicle has them.
The regular headlamp system should be turned on
when needed.
3-33

Footwell Lamps
For vehicles with footwell lamps, they are located
under the instrument panel and at the rear of the
front seats. These lamps provide soft light to the front
and rear oor areas. They dim with the instrument
panel cluster lights.
Footwell lighting brightness can be adjusted with the
instrument panel brightness control located below the
exterior lamps control. SeeInstrument Panel Brightness
on page 3-34. The footwell lights will turn off before
the instrument panel lights are at their lowest level of
brightness.
Battery Load Management
This feature monitors the vehicle’s electrical load and
determines when the battery is in a heavy discharge
condition. During times of high electrical loading, the
engine may idle at a higher revolutions per minute (rpm)
setting than normal to make sure the battery charges.
High electrical loads may occur when several of the
following are on: headlamps, high beams, fog lamps,
rear window defogger, the climate control fan at high
speeds, heated seats and engine cooling fans.If the battery continues to discharge, even with the
engine idling at a higher rpm setting, some electrical
loads will automatically be reduced. When this occurs,
the rear window defogger may take slightly longer
to clear the glass, the heated seats may not get as
warm as they usually do and the climate control fan
may cut back to a lower speed. For more battery
saving information, see “Battery Saver Active Message”
underDIC Warnings and Messages on page 3-73.
Electric Power Management
The vehicle has Electric Power Management (EPM) that
estimates the battery’s temperature and state of charge.
It then adjusts the voltage for best performance and
extended life of the battery.
When the battery’s state of charge is low, the voltage
is raised slightly to quickly bring the charge back up.
When the state of charge is high, the voltage is lowered
slightly to prevent overcharging. If the vehicle has a
voltmeter gage or a voltage display on the Driver
Information Center (DIC), you may see the voltage
move up or down. This is normal. If there is a problem,
an alert will be displayed.
