Notice:Your engine is designed to work with the
electronics in your vehicle. If you add electrical
parts or accessories, you could change the way the
engine operates. Before adding electrical equipment,
check with your dealer. If you don't, your engine
might not perform properly.
Engine Coolant Heater
If your vehicle has this feature, in very cold weather,
0ÉF (-18ÉC) or colder, the engine coolant heater
can help. You'll get easier starting and better fuel
economy during engine warm-up. Usually, the coolant
heater should be plugged in a minimum of four
hours prior to starting your vehicle. At temperatures
above 32ÉF (0ÉC), use of the coolant heater is not
required.
To Use the Engine Coolant Heater
1. Turn off the engine.
2. Open the hood and unwrap the electrical cord.
The engine coolant heater cord is located on the
passenger's side of the vehicle, above the headlamp
assembly.3. Plug it into a normal, grounded 110-volt AC outlet.
{CAUTION:
Plugging the cord into an ungrounded outlet
could cause an electrical shock. Also, the
wrong kind of extension cord could overheat
and cause a ®re. You could be seriously
injured. Plug the cord into a properly grounded
three-prong 110-volt AC outlet. If the cord
won't reach, use a heavy-duty three-prong
extension cord rated for at least 15 amps.
4. Before starting the engine, be sure to unplug and
store the cord as it was before to keep it away
from moving engine parts. If you don't, it could be
damaged.
How long should you keep the coolant heater plugged
in? The answer depends on the outside temperature, the
kind of oil you have, and some other things. Instead
of trying to list everything here, we ask that you contact
your dealer in the area where you'll be parking your
vehicle. The dealer can give you the best advice for that
particular area.

Mirrors
Manual Rearview Mirror
When you are sitting in a comfortable driving position,
adjust the mirror so you can see clearly behind your
vehicle. Grip the mirror in the center to move it up
or down and side to side. The day/night adjustment
allows you to adjust the mirror to avoid glare from any
headlamps behind you. Push the tab away from
you for daytime use; pull it toward you for night use.
Automatic Dimming Rearview Mirror
Your vehicle may have an automatic dimming rearview
mirror. Your vehicle's mirror may also contain OnStarž
controls. SeeOnStaržSystem on page 2-37for
more information.
At night, when the glare is too high, the mirror will
gradually darken to reduce glare. This change may take
a few seconds. The mirror will return to its clear
daytime state when the glare is reduced.
Mirror Operation
AUTO:Press this button to turn on the automatic
dimming feature.
OFF:Press this button to turn off the automatic
dimming feature.
O(On/Off):For mirrors equipped with OnStarž
controls, press this button to turn on the automatic
dimming feature. To turn off automatic dimming, press
this button again.
The indicator light will be illuminated when this feature
is active.
Automatic Dimming Rearview Mirror
with Compass
Your vehicle may have an automatic dimming rearview
mirror with a compass. Your vehicle's mirror may
also contain OnStar
žcontrols. SeeOnStaržSystem on
page 2-37for more information.
The mirror also includes an eight-point compass display
in the upper right corner of the mirror face.
When cleaning the mirror, use a paper towel or similar
material dampened with glass cleaner. Do not spray
glass cleaner directly on the mirror as that may cause
the liquid cleaner to enter the mirror housing.
2-33

The mirrors may also have an arrow that ¯ashes when
the turn signal is used. SeeTurn Signal/Multifunction
Lever on page 3-7.
Outside Curb View Assist Mirror
If you have the Memory Seat and Mirrors feature, the
passenger's outside rearview mirror includes a tilt-down
feature that operates when the shift lever is in
REVERSE (R). This feature assists the driver, improving
rear obstacle detection. When the vehicle is shifted
out of REVERSE (R), the passenger mirror will return to
its original position after a ®ve-second delay. This
delay prevents movement of the mirror if multiple gear
transitions (REVERSE (R) to AUTOMATIC
OVERDRIVE (
X) to REVERSE (R)) occur during a
parallel parking maneuver. This feature can be
programmed on or off through the personal choice
selection menu. See
DIC Vehicle Personalization on
page 3-50for programming instructions.
Outside Convex Mirror
Your passenger's side mirror is convex. A convex
mirror's surface is curved so you can see more from the
driver's seat.
{CAUTION:
A convex mirror can make things (like other
vehicles) look farther away than they really are.
If you cut too sharply into the right lane, you
could hit a vehicle on your right. Check your
inside mirror or glance over your shoulder
before changing lanes.
Outside Automatic Dimming
Heated Mirror
If you have this feature, the outside driver's mirror will
adjust for the glare of headlamps behind you. This
feature is controlled using the on and off settings on the
automatic dimming rearview mirror. See
Automatic
Dimming Rearview Mirror on page 2-33.
When you operate the rear window defogger, the
heated driver's and passenger's outside rearview mirrors
are warmed to help clear them of ice and snow. See
ªRear Window Defoggerº under
Climate Control System
on page 3-24orDual Automatic Climate Control
System on page 3-26for more information.

Horn
Press the center area of the steering wheel to sound
the horn.
Tilt Wheel
A tilt wheel allows you to adjust the steering wheel
before you drive. You can also raise it to the highest
level to give your legs more room when you exit
and enter the vehicle.
The lever that allows you to tilt the steering wheel is
located on the left side of the steering column.
To tilt the wheel, hold the
wheel and pull the lever
toward you. Then move the
wheel to a comfortable
position and release
the lever to lock the wheel
in place.
Turn Signal/Multifunction Lever
The lever on the left side of the steering column
includes the following:
·Turn and Lane-Change Signals
·Headlamp High/Low-Beam Changer
·Flash-To-Pass
·Windshield Wipers
·Windshield Washer
For more information on exterior lamps, see
Exterior
Lamps on page 3-14.

Turn and Lane-Change Signals
To signal a turn, move the lever on the left side of the
steering wheel all the way up or down. The lever returns
automatically when the turn is complete.
An arrow on the instrument
panel cluster will ¯ash in
the direction of the
turn or lane change.
If your vehicle is equipped with the Head-Up Display
(HUD), an arrow will also appear in the display area to
indicate the direction of the turn or lane change.
See
Head-Up Display (HUD) on page 3-20for more
information.
You may also have an arrow in the outside mirror that
¯ashes when the turn signal is used. See
Outside Power
Mirrors on page 2-35for more information.
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.
If the arrows ¯ash very fast as you signal a turn or a
lane change, a signal bulb may be burned out and other
drivers won't see your turn signal.If a bulb is burned out, replace it to help avoid an
accident. If the arrows don't go on at all when you signal
a turn, check the fuse. See
Fuses and Circuit Breakers
on page 5-86.
Turn Signal On Chime
If your turn signal is left on for more than 0.8 miles
(1.3 km), a chime will sound at each ¯ash of the turn
signal. To turn off the chime, move the turn signal lever
to the off position.
Headlamp High/Low-Beam Changer
To change the headlamps from low beam to high beam
or high beam to low beam, pull the turn signal lever
toward you and release it.
When the high beams are
on, this light located on the
instrument panel cluster
will also be on.
If your vehicle is equipped with the Head-Up Display
(HUD), this symbol will also appear in the display area to
indicate the high beams are on. See
Head-Up Display
(HUD) on page 3-20for more information.
3-8

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. It
works even if your headlamps are off.
Pull the turn signal lever toward you brie¯y to
¯ash-to-pass.
If the headlamps are off or on low beam, the high-beam
headlamps will turn on. They'll stay on as long as
you hold the lever toward you and the high-beam
indicator on the instrument panel cluster will come on.
Windshield Wipers
The windshield wipers are controlled by turning the
band marked WIPER.
If your windshield wipers are on for more than six
seconds while you are driving, the low-beam headlamps,
instrument panel cluster backlighting and taillamps will
turn on. For more information see ªWiper Activated
Headlampsº under
Exterior Lamps on page 3-14.
Off:Turn the band to OFF to turn the wipers off.
