Immobilizer Operation
Your vehicle has a passive theft-deterrent system.
The system is automatically armed when the ignition
mode transitions to OFF.
The immobilization system is disarmed when the ignition
mode transitions to ACCESSORY or START and a
valid transmitter is found in the vehicle.
You do not have to manually arm or disarm the system.
The security light will come on if there is a problem
with arming or disarming the theft-deterrent system.
The system has one or more keyless access
transmitters that are matched to an immobilizer control
unit in your vehicle. Only a correctly matched keyless
access transmitter will start the vehicle. If the keyless
access transmitter is ever damaged, you may not
be able to start your vehicle.
When trying to start the vehicle, if the engine does
not start and the security light comes on, there may
be a problem with your immobilizer system. Press the
START button again.If the vehicle does not start and the keyless access
transmitter appears to be undamaged, try another
keyless access transmitter. Or, you may try placing the
transmitter in the transmitter pocket. See “NO FOBS
DETECTED” underDIC Warnings and Messages
on page 3-63for additional information. At this time,
you may also want to check the fuse. SeeFuses
and Circuit Breakers on page 6-90. If the engine
still does not start with the other transmitter, your
vehicle needs service. If the engine does start, the
rst transmitter may be faulty. See your dealer/retailer
who can service the theft-deterrent system and
have a new keyless access transmitter programmed
to the vehicle.
It is possible for the immobilizer system to learn new or
replacement keyless access transmitters. Up to 4 keyless
access transmitters can be programmed for the vehicle.
To program additional transmitters, see “Matching
transmitter(s) to Your Vehicle” underKeyless Access
System Operation on page 2-6.
Do not leave the key or device that disarms or
deactivates the theft deterrent system in the vehicle.

Starting and Operating
Your Vehicle
New Vehicle Break-In
Notice:Your vehicle does not need an elaborate
break-in. But it will perform better in the long run if
you follow these guidelines:
Keep your speed at 55 mph (88 km/h) or less for
the rst 500 miles (805 km).
Do not drive at any one constant speed, fast or
slow, for the rst 500 miles (805 km). Do not
make full-throttle starts. Avoid downshifting to
brake or slow the vehicle.
Avoid making hard stops for the rst 200 miles
(322 km) or so. During this time the new brake
linings are not yet broken in. Hard stops
with new linings can mean premature wear and
earlier replacement. Follow this breaking-in
guideline every time you get new brake linings.
Following break-in, engine speed and load can be
gradually increased.
Ignition Positions
Your vehicle has an
electronic keyless ignition
with pushbutton start.
In order to shift out of PARK (P), the vehicle must be
running or in ACCESSORY mode and the regular brake
pedal must be applied.
/(START):Press this button while your foot is on
the brake to start the engine. The shifter must be
in PARK (P) or NEUTRAL (N) to start the engine and
the keyless access transmitter must be in the vehicle
for the ignition to work.
2-23

Page 84 of 470

9Acc. (OFF/ACCESSORY):When this button is
pressed, the engine will turn off even if the shifter is not in
PARK (P). If the shifter is in PARK (P), the ignition mode
will change to Retained Accessory Power (RAP), if all
doors are closed. The ignition mode will change to off, if a
front door is opened. SeeRetained Accessory Power
(RAP) on page 2-24for more information. If the shifter is
not in PARK (P), the ignition mode will change to Acc..
SeeShifting Into PARK (P) on page 2-32.
When the engine is off, press this button to place the
vehicle in accessory mode. ACCESSORY MODE ON will
display on the Driver Information Center (DIC). This mode
allows you to use things like the radio and the windshield
wipers while the engine is off. Use accessory mode if you
must have your vehicle in motion while the engine is off,
for example, if your vehicle is being towed. If the door is
open while in accessory mode, the key in reminder chime
will sound continuously.
If the push-button start is not working, your vehicle
may be near a strong radio antenna signal causing
interference to the keyless access system. SeeDIC
Warnings and Messages on page 3-63for more
information.
After being in ACCESSORY mode for about 20 minutes,
the vehicle will automatically enter RAP or will turn off,
depending on if the doors are opened or closed.Retained Accessory Power (RAP)
These vehicle accessories can be used for up to
10 minutes after the engine is turned off:
Audio System
Audio Steering Wheel Controls
Power Windows
Power to these accessories continues to work for up to
10 minutes or until a door is opened. For additional
10 minutes of operation, close all the doors and press
the Acc. button to place the vehicle in accessory mode.
Press the button again to return to RAP.
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 you 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 3-63for 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 3-63.3. 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 briey
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.
2-25

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 3-63for
more information.
Automatic Transmission Operation
There are several different positions for the shift lever.
PARK (P):This position locks the rear wheels. It is
the best position to use when you starting the engine
because your vehicle cannot move easily.
2-26

Page 87 of 470

{CAUTION:
It is dangerous to get out of your vehicle if the
shift lever is not fully in PARK (P) with the
parking brake rmly set. Your vehicle can roll.
Do not leave your vehicle when the engine
is running unless you have to. If you have
left the engine running, the vehicle can move
suddenly. You or others could be injured.
To be sure your vehicle will not move, even
when you are on fairly level ground, always
set your parking brake and move the shift
lever to PARK (P). SeeShifting Into PARK (P)
on page 2-32.
Be sure the shift lever is fully in PARK (P) before
starting the engine. Your vehicle has an automatic
transmission shift lock control system.You have to fully apply the regular brakes rst and
then press the shift lever button before you can shift
from PARK (P) when the vehicle is running. If you
cannot shift out of PARK (P), ease pressure on the shift
lever and push the shift lever all the way into PARK (P)
as you maintain brake application. Then press the
shift lever button and move the shift lever into another
gear. SeeShifting Out of PARK (P) on page 2-33.
REVERSE (R):Use this gear to back up.
Notice:Shifting to REVERSE (R) while your vehicle
is moving forward could damage the transmission.
The repairs would not be covered by your warranty.
Shift to REVERSE (R) only after your vehicle is
stopped.
To rock your vehicle back and forth to get out of snow,
ice, or sand without damaging your transmission,
seeIf Your Vehicle is Stuck in Sand, Mud, Ice, or Snow
on page 5-21.
2-27

Page 88 of 470

NEUTRAL (N):In this position, your engine does not
connect with the wheels. To restart when you are
already moving, use NEUTRAL (N) only. Also, use
NEUTRAL (N) when your vehicle is being towed.
Use Neutral (N) if the vehicle must be moved with the
engine off for short distances. Please seeTowing
Your Vehicle on page 5-27.
{CAUTION:
Shifting into a drive gear while the engine is
running at high speed is dangerous. Unless
your foot is rmly on the brake pedal, your
vehicle could move very rapidly. You could
lose control and hit people or objects. Do not
shift into a drive gear while your engine is
running at high speed.
Notice:Shifting out of PARK (P) or NEUTRAL (N)
with the engine running at high speed may damage
the transmission. The repairs would not be
covered by your warranty. Be sure the engine is not
running at high speed when shifting your vehicle.DRIVE (D):This position is for normal driving.
It provides the best fuel economy for your vehicle.
If you need more power for passing and you are:
Going less than about 35 mph (56 km/h),
push the accelerator pedal about halfway down.
Going about 35 mph (56km/h) or more, push the
accelerator all the way down.
Downshifting the transmission in slippery road conditions
could result in skidding, see “Skidding” underLoss of
Control on page 5-12.
Notice:Spinning the tires or holding the vehicle
in one place on a hill using only the accelerator
pedal may damage the transmission. The repair will
not be covered by your warranty. If you are stuck,
do not spin the tires. When stopping on a hill,
use the brakes to hold the vehicle in place.
Maximum engine speed is limited to protect driveline
components from improper operation.

Driver Shift Control (DSC)
The Driver Shift Control (DSC) feature lets you manually
control over the operation of the transmission.
To use this feature, move
the shift lever from the
DRIVE (D) position to the
left and into the driver
shift control gate.
The Sport Automatic Mode is selected by moving the
shift lever into the DSC area without shifting towards
the + (plus) or−(minus) symbols. While in the
Sport Automatic Mode, the transmission computer
determines when the vehicle is being driven in a
competitive manner. It then selects and holds the
transmission in lower gears giving more noticeable
upshifts for a sportier vehicle performance. Once you
shift to the + (plus) or−(minus) controls, the driver
manual gear selection is activated. A + (plus) symbol
appears on the shift console above the DRIVE (D)
indicator and minus symbol appears below the indicator.The Head-Up Display (HUD) also displays the requested
gear, though the actual upshift or downshift could be
delayed until the engine speed is correct for that gear.
The requested gear displays on the HUD until the
next time you upshift or downshift. The gear selected
and shown in the HUD is one of a number of gears
available. The vehicle does not upshift beyond
the chosen gear. The actual gear that the vehicle shifts
to depends on a combination of the driver-requested
gear range, vehicle speed and throttle position.
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.
If you do not upshift as the engine approaches the red
line on the engine RPM (Revolutions Per Minute) gage,
the engine speed is controlled to limit the engine RPM.
Not all manual downshift requests will be allowed by
the transmission. To prevent excessive engine RPMs,
each gear has a maximum vehicle speed associated
with it. Any downshift request above this speed is
not allowed by the transmission.
If shifting is prevented for any reason, the current
gear ashes multiple times in the Driver Information
Center (DIC), indicating that the transmission has
not shifted gears.
2-29

Page 90 of 470

Some automatic downshifts can occur to maintain
minimum engine speed. This only happens if the vehicle
is left in too high of a gear for the vehicle’s speed.
For example, if you have been driving in sixth gear
range and come to a stop without manually
downshifting, the transmission automatically downshifts
to rst gear and displays rst gear on the HUD. As
you begin to drive and accelerate, the transmission
remains in rst gear until the driver selects an upshift.
DSC can be used while using cruise control, but
transmission shifting is different while the cruise control
is on. This is not a malfunction and is necessary to
let proper operation of the cruise control.
To return to fully automatic operation, move the shift
lever to the right and back into DRIVE (D).
When accelerating your vehicle from a stop in snowy
and icy conditions, you may want to shift into second
gear. A higher gear lets you gain more traction on
slippery surfaces.
In higher gears, on the XLR only, an automatic downshift
occurs if you press the accelerator pedal to the oor.
This feature provides adequate acceleration capabilities
if you forget to downshift manually. Tap the shifter
forward and the vehicle upshifts.Parking Brake
The parking brake pedal is
located to the left of the
regular brake pedal,
near the driver’s door.
To set the parking brake, hold the regular brake pedal
down with your right foot and push the parking brake
pedal down with your left foot.
If the ignition is on, the parking brake indicator light
on the instrument panel cluster should come on.
If it does not, you need to have your vehicle serviced.
