Turn and Lane-Change Signals
To signal a turn, move the lever all the way up
or down. The lever returns automatically when the
turn is complete. If you momentarily press and
release the lever, the turn signal will ash 3 times.
An arrow on the
instrument panel
cluster and in the
outside rearview
mirror will ash in the
direction of the turn
or lane change.
Raise or lower the lever until the arrow starts to
ash to signal a lane change. Hold it there until
the lane change is complete. The lever returns
when it is released.
If the turn signal is left on, a warning chime will
sound and the Driver Information Center (DIC) will
display TURN SIGNAL ON after driving about a
mile to remind you to turn it off. SeeDIC Warnings
and Messages on page 246.Arrows that ash rapidly when signaling for a
turn or lane change may be caused by a burned
out signal bulb. Other drivers will not see the
turn signal.
Replace burned-out bulbs to help avoid possible
accidents. Check the fuse and for burned-out bulbs
if the arrow fails to work when signaling a turn.
SeeRear Underseat Fuse Block on page 455.
Headlamp High/Low-Beam Changer
Push forward to change the headlamps from
low beam to high. Pull the lever back and then
release it to change from high beam to low.
This light on the
instrument panel cluster
will be on, indicating
high-beam usage.

FCA is enabled when the green light on the button
is lit. FCA is disabled when the indicator light is
amber.
{CAUTION:
On winding roads, FCA may not detect
a vehicle ahead. You could crash into
a vehicle ahead of you. Do not rely on
FCA on winding roads.
When weather limits visibility,
such as in fog, rain, or snow, FCA
performance is limited. There may not
be enough warning distance to the
vehicle in front of you. Do not rely
on FCA in low visibility conditions.
{CAUTION:
When FCA is enabled, the Adaptive Cruise
Control switch is on. If you press another
Adaptive Cruise Control button, you might
CAUTION: (Continued)
CAUTION: (Continued)
go into cruise when you do not want to.
You could be startled and even lose
control. Be careful not to press adaptive
cruise buttons unless you want to use
cruise control.
Alerting the Driver
The FCA alert symbol
will ash and a warning
beep will sound when
driver action may be
required.
The alert symbol will ash when:
Your vehicle is approaching another vehicle
too quickly.
Your vehicle is following a vehicle ahead of
you much too closely.
SeeDefensive Driving on page 302for more
information.

Clear ice and snow from the wiper blades before
using them. If they are frozen to the windshield,
carefully loosen or thaw them. If the blades
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.
Clear away snow or ice to prevent an overload.
Your 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 197for more information.Rainsense™ II Wipers
If your vehicle has this feature, the moisture
sensor is mounted on the interior side of the
windshield behind the rearview mirror. It is used
to automatically operate the wipers by monitoring
the amount of moisture build-up on the windshield.
Wipes occur as needed to clear the windshield
depending on driving conditions and the sensitivity
setting. In light rain or snow, fewer wipes will occur.
In heavy rain or snow, wipes will occur more
frequently. The Rainsense™ II wipers operate in
a delay mode as well as a continuous low or high
speed as needed. If the system is left on for long
periods of time, occasional wipes may occur
without any moisture on the windshield. This is
normal and indicates that the Rainsense™ II
system is activated.
173

The Rainsense™ II system can be activated by
turning the wiper band to one of the ve sensitivity
levels indicated on the wiper stalk. The position
closest to off is the lowest sensitivity setting, level
one. This allows more rain or snow to collect on the
windshield between wipes. Turning the wiper band
away from you to higher sensitivity levels increases
the sensitivity of the system and frequency of
wipes. The highest sensitivity setting, level ve is
closest to low. A single wipe will occur each time
you turn the wiper stalk to a higher sensitivity level
to indicate that the sensitivity level has been
increased.
Notice:Going through an automatic car wash
with the wipers on can damage them. Turn
the wipers off when going through an
automatic car wash.The mist and wash cycles operate as normal and
are not affected by the Rainsense™ II function.
The Rainsense™ II system can be overridden at
any time by manually turning the wiper band to low
or high speed.
When Rainsense™ II is active, the headlamps
will turn on automatically. The headlamps will
turn off again once the wipers turn off if it is light
enough outside. If it is dark, they will remain
on. SeeWiper Activated Headlamps on page 197
for more information.
Notice:Do not place stickers or other items
on the exterior glass surface directly in front of
the moisture sensor. Doing this could cause
the moisture sensor to malfunction.

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 will only appear when
a vehicle is detected in your path.
If this symbol does not appear, or disappears
briey, Adaptive Cruise Control will not respond to
vehicles you may see ahead.{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 will automatically slow
your vehicle down when approaching a slower
moving vehicle. It will then adjust your speed to
follow the vehicle in front at the selected follow
distance. Your speed will increase or decrease
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.

IntelliBeam™ Intelligent High-Beam
Headlamp Control System
If your vehicle has this feature, be sure to read
this entire section before using it.
IntelliBeam™ is an enhancement to your vehicle’s
headlamp system. Using a digital light sensor
on your 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 238.
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
automatic 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 vehicle’s speed drops below
15 mph (24 km/h).
194

The headlamp stalk is moved forward to the
high-beam position or the ash-to-pass feature
is used. SeeHeadlamp High/Low-Beam
Changer on page 167andFlash-to-Pass
on page 172.
When either of these conditions occur, the
IntelliBeam™ feature is disabled and the
IntelliBeam™ light in the mirror turns off until
the high-beam stalk is returned to the neutral
position.
If IntelliBeam™ was using low-beams prior
to this action, the IntelliBeam™ feature is
temporarily disabled until the stalk is returned
to the neutral position.
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.
The IntelliBeam™ system is turned off at the
inside rearview mirror.IntelliBeam™ might not turn off the high-beams if
the system cannot detect other vehicle’s lamps
because of any of the following:
The other 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.

Wiper Activated Headlamps
This feature activates the headlamps and parking
lamps after the windshield wipers are turned
on and have completed eight wipe cycles within
four minutes.
When the ignition is turned to OFF, the
wiper-activated headlamps immediately turn off.
The wiper-activated headlamps also turn off if the
windshield wipers are turned off.
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. DRL can be helpful in many different
driving conditions, but they can be especially
helpful in the short periods after dawn and before
sunset. Fully functional daytime running lamps
are required on all vehicles rst sold in Canada.
The DRL system will make 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 transaxle is not in PARK (P)
(United States only).
The light sensor is covered or not detecting
light. See “Sensors” underDual Climate Control
System on page 210.
When DRL are on, no other exterior lamps such as
the parking lamps, taillamps, etc. will be on when
the DRL are being used. Your instrument panel will
not be lit up either.
197

When automatic lighting is on and it is dark enough
outside, the turn signal lamps will turn off and
normal low-beam headlamp operation will occur.
When automatic lighting is on and it is bright
enough outside, the regular lamps will go off, and
the DRL will take over. If you start your vehicle
in a dark garage, the automatic headlamp system
will come 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, your
instrument panel cluster may not be as bright as
usual. Make sure your instrument panel brightness
knob is in the full bright position. SeeInstrument
Panel Brightness on page 199.
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 your vehicle with the DRL off at night,
turn off automatic lighting and shift the transaxle
into PARK (P). Placing your vehicle in PARK (P)
disables the DRL. The DRL will stay off until you
shift out of PARK (P).To drive your vehicle with the DRL off, turn off
automatic lighting and manually turn on the parking
lamps or fog lamps (if equipped).
As with any vehicle, you should turn on the
regular headlamp system when you need it.
Fog Lamps
Use the fog lamps for better vision in foggy or
misty conditions.
-(Fog Lamps):The fog lamps button is
located on the exterior lamps control. The exterior
lamps control is located on the instrument panel
to the left of the steering column.
The ignition must be on for the fog lamps to work.
Press the exterior lamps button to turn the
fog lamps on or off. A light will come on in the
instrument panel cluster when the fog lamps
are in use.
When the headlamps are changed to high-beam,
the fog lamps will turn off. The fog lamps come
back on again when the high-beam headlamps
are turned off.
Some localities have laws that require the
headlamps to be on along with the fog lamps.
