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.

Charging System Light
This light comes on briey
when the ignition key is
turned to START, but
the engine is not running,
as a check to show it
is working.
If it does not, have the vehicle serviced by your
dealer/retailer.
The light should go out once the engine starts. If it stays
on, or comes on while driving, there could be a problem
with the charging system. A charging system message
in the Driver Information Center (DIC) can also appear.
SeeDIC Warnings and Messages on page 3-60for more
information. This light could indicate that there are
problems with a generator drive belt, or that there is an
electrical problem. Have it checked right away. If the
vehicle must be driven a short distance with the light
on, turn off accessories, such as the radio and air
conditioner.
Voltmeter Gage
When the vehicle is in
accessory mode, the
voltmeter shows the
voltage output of the
battery. When the engine
is running, it shows
the voltage output of the
charging system.
The reading will change as the rate of charge changes
(with engine speed, for example), but if the voltmeter
reads at 9 volts or below, the instrument panel cluster
and other systems may shut down. The Driver
Information Center (DIC) will read LOW VOLTAGE
when the vehicle is at 10 volts or below. Have it checked
right away. Driving with the voltmeter reading at
10 volts or below could drain the battery and disable
the vehicle.
