Starting the Engine
To place the transmission in the proper gear:
Move the shift lever to PARK (P) or NEUTRAL (N).
To restart when you are already moving, use
NEUTRAL (N).
Notice:Do not try to shift to PARK (P) if your
vehicle is moving. If you do, you could damage the
transmission. Shift to PARK (P) only when your
vehicle is stopped.
The keyless access transmitter must be inside the
vehicle for the ignition to work.Cell phone chargers can interfere with the operation of
the Keyless Access System. Battery chargers should
not be plugged in when starting or turning off the engine.
To start your vehicle, do the following:
Starting Procedure
1. With your foot on the brake pedal, press the
START button located on the instrument panel.
If there is not a keyless access transmitter in
the vehicle or if there is something causing
interference with it, the DIC will display NO FOBS
DETECTED. SeeDIC Warnings and Messages
on page 3-80for more information.
2. When the engine begins cranking, let go of the
button and the engine cranks automatically until
it starts. If the battery in the keyless access
transmitter is weak, the DIC displays KEY FOB
BATTERY LOW. You can still drive the vehicle.
See “Battery Replacement” underKeyless Access
System Operation on page 2-6for more information.
If the fob battery is dead, you need to insert the
fob into the fob slot to enable engine starting.
See “No Fobs Detected” underDIC Warnings and
Messages on page 3-80.
3. Do not race the engine immediately after starting it.
Operate the engine and transmission gently until
the oil warms up and lubricates all moving parts.

4. If the engine does not start and no DIC message is
displayed, wait 15 seconds before trying again to let
the cranking motor cool down.
If the engine does not start after 5-10 seconds,
especially in very cold weather (below 0°F or−18°C),
it could be ooded with too much gasoline.
Try pushing the accelerator pedal all the way to the
oor while cranking for up to 15 seconds maximum.
Wait at least 15 seconds between each try, to allow
the cranking motor to cool down. When the engine
starts, let go of the accelerator. If the vehicle starts
brie y but then stops again, do the same thing.
This clears the extra gasoline from the engine.
Notice:Cranking the engine for long periods of
time, by pressing the START button immediately
after cranking has ended, can overheat and damage
the cranking motor, and drain the battery. Wait at
least 15 seconds between each try, to allow the
cranking motor to cool down.
Your vehicle has a Computer-Controlled Cranking
System. This feature assists in starting the engine
and protects components. Once cranking has
been initiated, the engine continues cranking for a
few seconds or until the vehicle starts. If the engine
does not start, cranking automatically stops after
15 seconds to prevent cranking motor damage.To prevent gear damage, this system also prevents
cranking if the engine is already running.
Notice:The 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/retailer. If you do not, your
engine might not perform properly. Any resulting
damage would not be covered by your vehicle’s
warranty.
Stopping Your Engine
Move the shift lever to PARK (P) and press the Acc.
button located on the instrument panel. If the shifter is
not in PARK (P), the engine shuts off and the vehicle
goes into the Accessory Mode. The DIC displays SHIFT
TO PARK. Once the shifter is moved to PARK (P),
the vehicle turns off.
The DIC displays NO FOB, OFF OR RUN?, if the
keyless access transmitter is not detected inside the
vehicle when it is turned off.
SeeDIC Warnings and Messages on page 3-80for
more information.

Driver Shift Control (DSC)
Notice:If you drive your vehicle at high RPMs
without upshifting while using Driver Shift
Control (DSC), you could damage your vehicle.
Always upshift when necessary while using DSC.
Your automatic transmission has a Driver Shift
Control (DSC) feature that allows you to change
gears similar to a manual transmission.
To use the DSC feature:
1. Slide the shift lever over from DRIVE (D) to the
right into the DSC area.
When the transmission is
in DSC mode the sport
symbol in the Driver
Information Center (DIC)
will come on.
If you do not move the shift lever forward or
rearward, the vehicle will be in sport mode.
When you are in the sport mode the
vehicle will still shift automatically.While driving in sport mode, the transmission
may remain in a gear longer than it would in
normal driving mode based on braking, throttle
input, and vehicle lateral acceleration.
2. Press the shift lever forward to upshift or rearward
to downshift.
The DIC will show the
driver’s selection when
moving the shift lever
forward or rearward.
SeeDriver Information
Center (DIC) on page 3-74
for more information on
the DIC.
When using the DSC mode, the number displayed on
the Driver Information Center (DIC) indicates the
gear that the transmission is in. When starting the
vehicle from a stopped condition, only First (1) and
Second (2) gear may be used.
While using the DSC feature the vehicle will have rmer
shifting and increased performance. You can use this
for sport driving or when climbing/descending hills
to stay in gear longer or to down shift for more power or
engine braking.

Automatic Dimming Rearview Mirror
with OnStar
®and Compass
Your vehicle may have an automatic dimming rearview
mirror with a compass display. The mirror also
contains OnStar
®controls. For more information see
OnStar®System on page 2-48.
The mirror 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.
Mirror Operation
O
(On/Off):Press and hold the button, located on
the lower left side of the mirror face, for about
three seconds to turn the automatic dimming feature on
or off. 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
untilaCisshown in the compass display.
2-41
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.
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. SeeCompass
Calibrationlisted previously.

Object Detection Systems
Ultrasonic Rear Parking Assist
(URPA)
If your vehicle has the Ultrasonic Rear Parking Assist
(URPA) system, it helps you park easier and avoid other
vehicles while in REVERSE (R). It operates at speeds
less than 3 mph (5 km/h). It can determine how close
objects are to the rear bumper, up to 5 feet (1.5 m)
behind your vehicle. The distance sensors are located
on the rear bumper.
{CAUTION:
The Ultrasonic Rear Parking Assist (URPA)
system does not replace driver vision.
It cannot detect:
objects that are below the bumper,
underneath the vehicle, or if they are
too close or far from the vehicle
children, pedestrians, bicyclists, or pets.
CAUTION: (Continued)
CAUTION: (Continued)
If you do not use proper care before and while
backing; vehicle damage, injury, or death
could occur. Even with URPA, always check
behind your vehicle before backing up. While
backing, be sure to look for objects and check
your vehicle’s mirrors.
The display is located in
the dome lamp and can be
seen by looking over
your right shoulder.
URPA uses three color-coded lights to provide distance
and system information.
