Immobilizer Operation
The vehicle has a passive theft-deterrent system.
The system is automatically armed when the ignition is
turned off.
The immobilization system is disarmed when the ignition
is turned to OFF/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 comes 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 the
vehicle. Only a correctly matched keyless access
transmitter starts the vehicle. The vehicle may not
start if the keyless access transmitter is damaged.
If the engine does not start and the security light comes
on, there may be a problem with the 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, place the transmitter in
the transmitter pocket. See “NO FOBS DETECTED”
underDIC Warnings and Messages on page 3-60for
additional information. Check the fuse. SeeFuses and
Circuit Breakers on page 6-83. If the engine still does not
start with the other transmitter, the vehicle needs service.
If the engine does start, the rst transmitter may be faulty.
See your dealer/retailer or have a new keyless access
transmitter programmed to the vehicle.
The immobilizer system can learn new or replacement
keyless access transmitters. Up to four 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 2-5.
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
The vehicle has an
electronic keyless ignition
with push-button start.
In order to shift out of P (Park), the vehicle must be
running or in OFF/ACCESSORY mode and the regular
brake pedal must be applied.
/(START):Press while your foot is on the brake to
start the engine. The shifter must be in P (Park) or

transmitter must be in the vehicle for the ignition to work.
2-24

9Acc. (OFF/ACCESSORY):When this button is
pressed, the engine will turn off even if the shifter is not
in P (Park). If the shifter is in P (Park), 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 2-25for more information.
If the shifter is not in P (Park), the ignition mode will
change to Acc. SeeShifting Into Park on page 2-33.
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 the vehicle in motion while the engine is off, for
example, if the 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, the vehicle may be
near a strong radio antenna signal causing interference to
the keyless access system. SeeDIC Warnings and
Messages on page 3-60for 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.

Starting the Engine
To place the transmission in the proper gear:
Move the shift lever to P (Park) or N (Neutral). To restart
the engine when the vehicle is already moving, use
N (Neutral).
Notice:Do not try to shift to P (Park) if the
vehicle is moving. If you do, you could damage
the transmission. Shift to P (Park) only when
the 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 the 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 3-60for 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 2-5for 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 3-60.
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.
2-26

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.
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.
The 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 the 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, the engine
might not perform properly. Any resulting damage
would not be covered by the vehicle warranty.
Stopping the Engine
Move the shift lever to P (Park) and press the Acc. button
located on the instrument panel. If the shifter is not in
P (Park), the engine shuts off and the vehicle goes into
the Accessory Mode. The DIC displays SHIFT TO PARK.
Once the shifter is moved to P (Park), 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 3-60for
more information.

Emissions Inspection and
Maintenance Programs
Some state/provincial and local governments have or
might begin programs to inspect the emission control
equipment on the vehicle. Failure to pass this inspection
could prevent getting a vehicle registration.
Here are some things to know to help the vehicle pass
an inspection:
The vehicle will not pass this inspection if the check
engine light is on with the engine running.
To perform a check engine light bulb check with the
keyless ignition, make sure the transmitter fob is in
the passenger compartment. SeeIgnition Positions
on page 2-24. Press the bottom of the Acc. button on
the instrument panel and hold the button down for
ve seconds. The instrument panel, including the
check engine light, will light up and the ignition will be
on, but the engine will not start — press the bottom
of the Acc. button only briey, less than ve seconds,
the accessory power mode will be turned on, but not
the ignition. After the bulb check, press and release
the Acc. button again to turn the ignition off and avoid
draining the vehicle’s battery.
The vehicle will not pass this inspection if the
OBD II (on-board diagnostic) system determines
that critical emission control systems have not
been completely diagnosed by the system.
The vehicle would be considered not ready for
inspection. This can happen if the battery has
recently been replaced or if the battery has run down.
The diagnostic system is designed to evaluate critical
emission control systems during normal driving.
This can take several days of routine driving. If this
has been done and the vehicle still does not pass the
inspection for lack of OBD II system readiness, your
dealer/retailer can prepare the vehicle for inspection.
