Turn Signal/Multifunction Lever
The lever on the left side of the steering column
includes the following:
GTurn and Lane Change Signals. See
Turn and Lane-Change Signals on page 173.

=Rear Window Washer. SeeWindshield
Washer on page 175.
For information on the headlamps, seeExterior
Lamps on page 181.
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.
173

To signal a lane change, just 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.
As you signal a turn or a lane change, if the arrow
ashes faster than normal, a signal bulb may be
burned out and other drivers will not see your turn
signal.
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 check
the fuse. SeeBulb Replacement on page 443and
Fuses and Circuit Breakers on page 497.
If you have a trailer towing option with added
wiring for the trailer lamps, the signal indicator will
ash at a normal rate even if a turn signal bulb
is burned out. Check the front and rear turn signal
lamps regularly to make sure they are working.
Turn Signal On Chime
If either turn signal is left on for more than
3/4 mile (1.2 km), a chime will sound to let the
driver know to turn it off. If you need to leave the
signal on for more than 3/4 mile (1.2 km), turn
off the signal and then turn it back on.
Headlamp High/Low-Beam Changer
To change the headlamps from low beam to
high beam, push the turn signal/multifunction lever
away from you.
When the high beams
are on, this light
will appear on the
instrument panel cluster.
To change the headlamps from high beam to low
beam, pull the turn signal/multifunction lever
toward you.
Flash-to-Pass
When the headlamps are off, pull the lever toward
you to momentarily turn on the high beams.
This will signal that you are going to pass. When
you release the lever, they will turn off.

Exterior Lamps
The control to the
left of the steering
column operates
the exterior lamps.
9(Off):Turn the control to this position to
toggle off all lamps. This is a momentary control
that will spring back to AUTO when released.
This momentary control will turn the automatic
headlamps and/or the Daytime Running Lamps on
and off for U.S. vehicles. For vehicles rst sold
in Canada, this is only true when the transaxle
is in PARK (P).AUTO (Automatic):Turn the control to this
position to set your headlamps in automatic mode.
AUTO mode, if enabled, will turn the exterior
lamps on and off automatically depending on how
much light is available outside the vehicle.
Due to the momentary switch design, your
automatic lights may be disabled even if the
control is in the AUTO position.
;(Parking Lamps):Turn the control to this
position to turn on the parking lamps together with
the following:
Taillamps
Instrument Panel Lights
5(Headlamps):Turn the control to this position
to turn on the headlamps, together with the
previously listed lamps and lights.

Wiper Activated Headlamps
This feature, if equipped, will automatically
activate the headlamps and parking lamps after
the windshield wipers have been in use for
about 30 seconds and when all of the following
conditions are met.
The exterior lamp control is in AUTO.
The headlamps have not already been
activated by automatic lighting.
The automatic lighting feature has not been
disabled using the exterior lamp control.
SeeExterior Lamps on page 181for additional
information.
If the wipers are activated for over 30 seconds
and the exterior lamp control is in the parking
lamps position, or the automatic lighting feature
has been disabled using the exterior lamp control,
a HEADLAMPS SUGGESTED message will
appear on the Driver Information Center,
if equipped.
Headlamps on Reminder
If you turn the ignition to LOCK while leaving the
lamps on, you will hear a warning chime once
the driver’s door is opened.
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 will make front parking and
turn signal lamps come on in daylight when the
following conditions are met:
The ignition is on.
The exterior lamps control is off.
182

When the DRL are on, only your front turn signal
lamps will be on. Your instrument panel will
not be lit up.
When it is dark enough outside, the exterior lamps
will come on automatically. When it is bright
enough outside, the exterior lamps will turn off
and the DRL will turn on. Of course, you may still
turn on the headlamps any time you need to.
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 30 seconds for the automatic
headlamp system to change to DRL if it is
light outside. During that delay, your instrument
panel cluster may not be as bright as usual. Make
sure your instrument panel brightness control is
in the full bright position. SeeInstrument
Panel Brightness on page 183.
To idle your vehicle with the DRL and automatic
headlamps off, toggle the exterior lamp control
to off after starting the vehicle.
As with any vehicle, you should turn on the
regular headlamp system when you need it.Instrument Panel Brightness
The knob to adjust
the instrument panel
brightness is located
in the center of the
interior lamp controls.
Turn the knob clockwise to brighten the lights and
counterclockwise to dim them.
183

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 Battery
Voltage Low. If this message is displayed, it is
recommended that the driver reduce the electrical
loads as much as possible.Battery Run-Down Protection
Your vehicle has a feature to help prevent you
from draining the battery, in case you accidentally
leave the interior lamps on. If you leave any
interior lamps on while the ignition is in lock or off,
they will automatically turn off after 10 minutes.
The lamps will not come back on again until
you do one of the following:
Turn the ignition to RUN or ACCESSORY
Open a closed door, or close and reopen
a door.
Turn the interior lamps on if they are in the
door or override position.
Turn the interior lamps to the door or override
position and then to on again if the interior
lamp control is in the on position.
If your vehicle has less than 15 miles (25 km)
on the odometer, the battery saver will turn off
the lamps after only three minutes.
