Turn Signal/Multifunction Lever
The lever on the left side of the steering column includes
the following:
GTurn and Lane Change Signals.SeeTurn
and Lane-Change Signals on page 3-8.
3Headlamp High/Low-Beam Changer.See
Headlamp High/Low-Beam Changer on page 3-9.
Flash-to-Pass. SeeFlash-to-Pass on page 3-9.
NWindshield Wipers.SeeWindshield Wipers
on page 3-9.
LWindshield Washer.SeeWindshield Washer
on page 3-10.
For information on the headlamps, seeExterior Lamps
on page 3-14.
Turn and Lane-Change Signals
The turn signal has two upward (for right) and
two downward (for left) positions. These positions
allow you to signal a turn or a lane change.
To signal a turn, move the lever all the way up or
down. When the turn is nished, the lever will return
automatically.
An arrow on the instrument
panel cluster will ash
in the direction of the
turn or lane change.
To signal a lane change, raise or lower the lever until
the arrow starts to ash. Hold it there until you complete
your lane change. The lever will return by itself when
you release it. If you momentarily press and release the
lever, the turn signal will ash three times.
If the arrow ashes faster than normal as you signal a
turn or a lane change, a signal bulb may be burned
out and other drivers will not see your turn signal.
3-8

If a bulb is burned out, replace it to help avoid an
accident. If the arrows do not go on at all when you
signal a turn, check for burned-out bulbs and then check
the fuse. SeeFuses and Circuit Breakers on
page 5-100.
Turn Signal On Chime
If either one of the turn signals are left on and you have
drove more than 3/4 mile (1.2 km), a chime will sound.
Headlamp High/Low-Beam
Changer
To change the headlamps from low beam to high beam,
push the turn signal/multifunction lever toward the
front of the vehicle.
This light on the instrument
panel cluster comes on
if the high beam lamps
are turned on while
the ignition is on.
To change the headlamps from high beam to low beam,
pull the turn signal lever toward the rear of the vehicle.
Flash-to-Pass
With the turn signal lever in the low-beam position,
pull the lever toward you momentarily to switch
to high-beam, to signal that you are going to pass.
If the headlamps are on, they will return to low-beam
when the lever is released.
Windshield Wipers
Clear ice and snow from the wiper blades before
using them. If they are frozen to the windshield, gently
loosen or thaw them. Damaged wiper blades may
not clear the windshield well, making it harder to see
and drive safely. If the blades do become damaged,
install new blades or blade inserts. For more information,
seeWindshield Wiper Blade Replacement on page 5-47.
Heavy snow or ice can overload the wiper motor.
A circuit breaker will stop the motor until it cools down.
Clear away snow or ice to prevent an overload.
Turn the band with the wiper symbol to control the
windshield wipers.

Daytime Running Lamps (DRL)/
Automatic Headlamp System
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.
A light sensor on top of the instrument panel makes
the DRL work, so be sure it is not covered.
The DRL system’s automatic headlamp control will
make the low-beam headlamps come on at a reduced
brightness when the following conditions are met:
The ignition is in the ON/RUN position.
The exterior lamps control is in AUTO.
The engine is running.
When the DRL are on, only the low-beam headlamps,
at a reduced level of brightness, will be on. The
headlamps, taillamps, sidemarker, and other lamps
will not be on. The instrument panel and cluster will
also not be lit.
When it is dark enough outside, the low-beam
headlamps will turn off and the headlamps and parking
lamps will turn on. The other lamps that come on
with the headlamps will also come on.When it is bright enough outside, the headlamps will
go off and the DRL will come on.
As with any vehicle, you should turn on the regular
headlamp system when it is needed.
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.
3-16

Reading Lamps
The vehicle has reading lamps that also act as the
dome lamp. Press the button to turn them on and off.
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 put the charge back in.
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.
The battery can be discharged at idle if the electrical
loads are very high. This is true for all vehicles.
This is because the generator (alternator) may not be
spinning fast enough at idle to produce all the power
that is needed for very high electrical loads.A high electrical load occurs when several of the
following loads are on: headlamps, high beams,
fog lamps, rear window defogger, climate control fan
at high speed, heated seats, engine cooling fans,
trailer loads, and loads plugged into accessory power
outlets.
EPM works to prevent excessive discharge of the
battery. It does this by balancing the generator’s output
and the vehicle’s electrical needs. It can increase
engine idle speed to generate more power, whenever
needed. It can temporarily reduce the power demands
of some accessories.
Normally, these actions occur in steps or levels, without
being noticeable. In rare cases at the highest levels
of corrective action, this action may be noticeable
to the driver. If so, a Driver Information Center (DIC)
message might be displayed, such as Battery Saver
Active or Service Battery Charging System. If this
message is displayed, it is recommended that the
driver reduce the electrical loads as much as possible.
SeeDIC Warnings and Messages on page 3-66.

The HUD information can be displayed in one of
three languages, English, French, or Spanish. The
speedometer reading and other numerical values
can be displayed in either English or metric units.
The language selection and the units of measurement
are changed through the trip computer in the
Driver Information Center (DIC). SeeDIC Vehicle
Customization (With DIC Buttons) on page 3-75.
The HUD information appears as an image focused
out toward the front of the vehicle.When the ignition key is turned to RUN, the HUD will
display an introductory message for a short time,
until the HUD is ready.
The following indicator lights come on the instrument
panel when activated and will also appear on the HUD:
Turn Signal Indicators
High-Beam Indicator Symbol
The HUD will temporarily display CHECK GAGES and
ICE POSSIBLE when there are messages on the
DIC trip computer.
The HUD will also display the following messages on
vehicles with these systems, when they are active:
TRACTION CONTROL ACTIVE
STABILITRAK ACTIVE
Notice:If you try to use the HUD image as a parking
aid, you may misjudge the distance and damage your
vehicle. Do not use the HUD image as a parking aid.
When the HUD is on, the speedometer reading will
continually be displayed. The current radio station
or CD track number will display for a short period of
time after the radio or CD track status changes.
This will happen whenever radio information is changed.
The speedometer size will be reduced when radio,
CD information, warnings, or turn-by-turn navigation
information are displayed on the HUD.
