Retained Accessory Power (RAP)
These vehicle accessories can be used for up to
20 minutes after the engine is turned off:
Audio System
Audio Steering Wheel Controls
Power Windows
Power to these accessories will work up to 20 minutes
or until one of the front doors is opened. For an additional
20 minutes of operation, close all the doors and press
Acc. 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 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 3-79for 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 3-79.

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.
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 brie y 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 3-79for
more information.
Engine Coolant Heater
The engine coolant heater can provide easier starting
and better fuel economy during engine warm-up in cold
weather conditions at or below 0°F (−18°C). Vehicles with
an engine coolant heater should be plugged in at least
four hours before starting. Some models have an internal
thermostat in the cord which will prevent engine coolant
heater operation at temperatures above 0°F (−18°C).
To Use the Engine Coolant Heater
1. Turn off the engine.
2. Open the hood and unwrap the electrical cord.
For the 3.6L V6 and 4.4L V8 engine, the cord is
located in the front of the engine compartment,
on the passenger side of the vehicle.
For the 4.6L V8 engine, the cord is located in the
engine compartment on the driver side of the vehicle
near the inner fender and above the strut.
3. You must remove the plastic cap to access
the plug.
4. 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 will not reach, use a heavy-duty
three-prong extension cord rated for at least
15 amps.

Driver Shift Control (DSC)
Notice:If you drive the vehicle at high RPMs
without upshifting while using Driver Shift
Control (DSC), you could damage the vehicle.
Always upshift when necessary while using DSC.
Driver Shift Control (DSC) allows you shift an automatic
transmission similar to a manual transmission.
To use the DSC feature:
1. Move the shift lever to the right from D (Drive) into
the DSC area.
When in DSC mode, the
sport symbol will appear
in the Driver Information
Center (DIC).
The vehicle will remain in sport mode if the
shift lever is not moved. Sport mode will shift
automatically but remain in a gear longer then it
would in normal driving mode based on braking
and acceleration.2. Press the shift lever forward to upshift or rearward
to downshift.
When using the DSC
mode, the number
displayed on the Driver
Information Center (DIC)
indicates the gear that
the transmission is in.
SeeDriver Information
Center (DIC) on page 3-72
for more information on
the DIC.
When starting the vehicle from a stopped condition,
only 1 (First) and 2 (Second) 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.
The transmission will only allow you to shift into
gears appropriate for the vehicle speed and engine
Revolutions Per Minute (RPM). The transmission will
not automatically shift to the next higher gear if the
engine RPM is too high.
