Central Door Unlocking System
Your vehicle has a central door unlocking mode and a
theft-deterrent system. When unlocking the driver's door,
you can unlock the other doors by holding the key in
the turned position for a few seconds or by quickly
turning the door key twice in the lock cylinder.
Power Door Locks
The power door lock
switches are located on
the door panels near
the windows.
Press the bottom part of the power door lock switch
located on either front door to lock all of the doors
at once. Press the top of the switch to unlock all of the
doors at once.The power door lock switches located on the rear doors
can also lock all the doors at once by pressing the
bottom part of them, but they cannot unlock the doors.
Programmable Automatic Door
Locks
Your vehicle is programmed so that, when the doors are
closed, the ignition is on and the shift lever is moved
out of PARK (P), all the doors will lock. The doors
will unlock every time you stop the vehicle and move
the shift lever into PARK (P).
If someone needs to get out while your vehicle is not in
PARK (P), have the person use the manual lever or
power door lock switch. When the door is closed again,
it will not lock automatically. Use the manual lever or
power door lock switch to lock the door.
With the vehicle in PARK (P) and the ignition in ON, the
door locks can be programmed through prompts
displayed on the Driver Information Center (DIC). These
prompts allow the driver to choose various lock and
unlock settings. For programming information, see
DIC
Vehicle Personalization on page 3-67.

Here are examples for using THIRD (3) instead of
AUTOMATIC OVERDRIVE (
X).
·When driving on hilly, winding roads.
·When towing a trailer, so there is less shifting
between gears.
·When going down a steep hill.
SECOND (2):This position gives you more power. You
can use SECOND (2) on hills. It can help control your
speed as you go down steep mountain roads, but then
you would also want to use your brakes off and on.
Notice:Don't shift into SECOND (2) unless you are
going slower than 65 mph (105 km/h), or you can
damage your engine.
FIRST (1):This position gives you even more power
than SECOND (2). You can use it on very steep hills, or
in deep snow or mud. (If the shift lever is put in FIRST
(1), the transaxle won't shift into ®rst gear until the
vehicle is going slowly enough.)
Notice:If your front wheels won't turn, don't try to
drive. This might happen if you were stuck in
very deep sand or mud or were up against a solid
object. You could damage your transaxle. Also,
if you stop when going uphill, don't hold your
vehicle there with only the accelerator pedal. This
could overheat and damage the transaxle. Use your
brakes to hold your vehicle in position on a hill.
Performance Shifting (DTS Only)
When your vehicle detects a change in driving
conditions, it will automatically initiate the appropriate
performance shift mode. When this occurs, the
gear display on the instrument panel cluster will change
to indicate that the transaxle has shifted to a different
gear. For example, the gear display on the cluster may
indicate 3 or 2 even though the gearshift is still in
AUTOMATIC OVERDRIVE (
X). Once the performance
shift mode ends, the gear display on the instrument
panel cluster will return to normal.
Shift Lock Release
This vehicle is equipped with an electric shift lock
release system. The shift lock release is designed to do
the following:
·Prevent the ignition key from being removed unless
the shift lever is in PARK (P), and
·prevent movement of the console shift lever
(DTS only) out of PARK (P) unless the ignition is in
a position other than OFF. The shift lock release
is always functional except in the case of a
dead battery or low voltage (less than 9 V) battery.
The following procedure allows the ignition to be turned
to OFF and for ignition key removal in case of a
dead battery or low voltage battery for vehicles equipped
with a column shift lever.

Mirrors
Automatic Dimming Rearview Mirror
with OnStar
ž
Your vehicle may have an automatic dimming rearview
mirror with OnStaržsystem controls. For more
information about OnStarž, seeOnStaržSystem on
page 2-45.
When the automatic dimming feature is turned on, the
mirror automatically changes to reduce glare from
headlamps behind you. A photocell on the mirror senses
when it is becoming dark outside. Another photocell
built into the mirror face senses when headlamps
are behind you.
At night, when the glare is too bright, 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
O
(On/Off):This is the on/off button, located on the
lower left side of the mirror face.
To turn the automatic dimming feature on or off, press
the on/off button. The indicator light will be illuminated
when the automatic dimming feature is on.
Cleaning the Mirror
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.
Automatic Dimming Rearview Mirror
with OnStar
žand Compass
Your vehicle may have an automatic dimming rearview
mirror with a compass display. The mirror also
contains OnStar
žcontrols. For more information seeOnStaržSystem on page 2-45.
The automatic dimming feature functions the same as
that of the automatic dimming rearview mirror without a
compass. See
Automatic Dimming Rearview Mirror
with OnStaržon page 2-40.
The mirror also includes an eight-point compass display
in the upper right corner of the mirror face. When on,
the compass automatically calibrates as the vehicle
is driven.
2-40

Mirror Operation
O
(On/Off):The on/off button is located on the lower
left side of the mirror face for the automatic dimming and
compass functions of the rearview mirror.
To turn on the automatic dimming feature, press and hold
the on/off button for about three seconds. To turn off
automatic dimming, press and hold the on/off button for
about three seconds again. The indicator light will
illuminate when this feature is active. The automatic
dimming feature is active each time the vehicle is started.
Compass Operation
Press the on/off button once to turn the compass on
or off.
When the ignition and the compass feature are on, the
compass will show two character boxes for about
two seconds. After two seconds, the mirror will display
the compass heading.
Compass Calibration
If after two seconds, the display does not show a
compass heading (for example, N for North), there may
be a strong magnetic ®eld interfering with the compass.
Such interference may be caused by a magnetic antenna
mount, magnetic note pad holder or a similar magnetic
item. If the letter C should ever appear in the compass
window, the compass may need calibration.The mirror can be calibrated by driving the vehicle in
circles at 5 mph (8 km/h) or less until the display reads a
direction.
The compass can be placed in calibration mode
manually by pressing and holding the on/off button until
a C is shown in the compass display.
Compass Variance
The zone is set to zone eight upon leaving the factory.
It will be necessary to adjust the compass to
compensate for compass variance if you live outside
zone eight. Under certain circumstances, as during
a long distance cross-country trip, it will be necessary to
adjust for compass variance. Compass variance is
the difference between earth's magnetic north and true
geographic north. If not adjusted to account for
compass variance, your compass could give false
readings.
To adjust for compass variance do the following:
1. Find the current location and variance zone number
on the following zone map.
2. Press and hold the on/off button until a zone
number appears in the display.
2-41

3. Once the zone number appears in the display,
press the on/off button quickly until the correct
zone number appears in the display. Stop pressing
the button and the mirror will return to normal
operation. If C appears in the compass window, the
compass may need calibration. See
Compass
Calibrationlisted previously.
Cleaning the Mirror
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.
Outside Power Mirrors
The control on the driver's
door armrest operates both
outside rearview mirrors.
Press (R) on the selector switch to choose the right
mirror or (L) to choose the left mirror. The center position
is off and will not allow the mirrors to move if the
control pad is touched.
To adjust a mirror, press the arrows on the control pad
to move the mirror in the direction you want the
mirror to go. Adjust each mirror so you can see the side
of your vehicle and the area behind your vehicle.

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.
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's 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.
Arrows that ¯ash rapidly when signaling for a turn or lane
change may be caused by a burned out signal bulb.
Other drivers won't 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. See
Fuses and
Circuit Breakers on page 5-94.
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.
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.
Pull and hold the turn signal lever toward you
to use. When you do, the following will occur:
·If the headlamps are either off or in the Daytime
Running Lamps (DRL) mode, the high-beam
headlamps will turn on. They'll stay on as long as
you hold the lever there. Release the lever to
turn them off.
·If the headlamps are on high beam, they will switch
to low beam. To return to high beam, push the
lever away from you.

The RainsenseŸ 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 LO. 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:The wipers must be turned off when going
through a car wash to avoid damage.
The MIST and wash cycles operate as normal and are
not affected by the RainsenseŸ function. The
RainsenseŸ system can be overridden at any time by
manually turning the wiper band to LO or HI speed.
When RainsenseŸ 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. See ª Wiper-Activated
Headlampsº under
Exterior Lamps on page 3-15for 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.
Windshield Washer
{CAUTION:
In freezing weather, don't use your washer
until the windshield is warmed. Otherwise the
washer ¯uid can form ice on the windshield,
blocking your vision.
At the top of the turn signal/multifunction lever there is a
paddle with the word PUSH on it. To spray washer
¯uid on the windshield, press and release this paddle.
The wipers will clear the windshield and either stop
or return to your preset speed. For more washer cycles,
press and hold the paddle.
CHECK WASHER FLUID will be displayed on the Driver
Information Center (DIC) when the washer ¯uid
reaches a low level.
