Starting Procedure
(Keyless Access)
1. If the vehicle has the keylessaccess system, the transmitter
must be in the vehicle. Put
your foot on the brake pedal
and push the START button.
When the engine begins
cranking, let go of the button.
The idle speed will go down
as your engine gets warm.
Do not race the engine
immediately after starting it.
Operate the engine and
transmission gently to allow
the oil to warm up and lubricate
all moving parts.
If the transmitter is not in
the vehicle or something is
interfering with the transmitter,
the Driver Information Center (DIC) will display NO REMOTE
DETECTED. See
Driver
Information Center (DIC) on
page 5‑25 for more information.
If the battery in the keyless
access transmitter needs
replacing, the DIC displays
REPLACE BATTERY IN
REMOTE KEY. The vehicle
can still be driven. See “Starting
the Vehicle with a Low
Transmitter Battery” inRemote
Keyless Entry (RKE) System
Operation on page 2‑4 for
more information.
The vehicle has a
Computer-Controlled Cranking
System. This feature assists
in starting the engine and
protects components. If the
START button is pressed, and
then released when the engine begins cranking, the engine
will continue cranking for a few
seconds or until the vehicle
starts. If the engine does not
start and the button is pressed
for many seconds, cranking will
be stopped after 15 seconds to
prevent cranking motor damage.
To prevent gear damage, this
system also prevents cranking
if the engine is already running.
Engine cranking can be stopped
by pressing the START button a
second time.
Notice: Cranking the engine for
long periods of time, by returning
the key to the START position
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 let the
cranking motor cool down.

2. If the engine does not start after5‐10 seconds, especially in very
cold weather (below −18°C or
0°F), it could be flooded with too
much gasoline. Try pushing the
accelerator pedal all the way
to the floor and holding it there
as you hold the key in START,
or press the START button, for
up to a maximum of 15 seconds.
Wait at least 15 seconds
between each try, to allow the
cranking motor to cool down.
When the engine starts, let go
of the key or button, and the
accelerator. If the vehicle starts
briefly but then stops again,
do the same thing. This clears
the extra gasoline from the
engine. 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.Engine Heater
The engine coolant heater,
if available, can help in cold weather
conditions at or below −18°C (0°F)
for easier starting and better fuel
economy during engine warm-up.
Plug in the coolant heater at least
four hours before starting the
vehicle. An internal thermostat in
the plug-end of the cord will prevent
engine coolant heater operation at
temperatures above −18°C (0°F).
To Use the Engine Coolant
Heater
1. Turn off the engine.
2. Open the hood and unwrap the
electrical cord.
V6 Engine
The electrical cord is located
on the driver side of the
engine compartment, between
the fender and the engine
compartment fuse block on
vehicles with a six cylinder
engine.

{WARNING
It is dangerous to get out of the
vehicle if the shift lever is not fully
in P (Park) with the parking brake
firmly set. The vehicle can roll.
Do not leave the 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 the
vehicle will not move, even when
you are on fairly level ground,
always set the parking brake and
move the shift lever to P (Park).
SeeShifting Into Park on
page 9‑25. If you are pulling a
trailer, see Driving Characteristics
and Towing Tips on page 9‑56.
Make sure the shift lever is fully in
P (Park) before starting the engine.
The vehicle has an automatic
transmission shift lock control
system. The regular brake must be fully applied first and then the
shift lever button pressed before
shifting from P (Park) when the
ignition key is in ON/RUN. If you
cannot shift out of P (Park), ease
pressure on the shift lever, then
push the shift lever all the way
into P (Park) as you maintain brake
application. Then press the shift
lever button and move the shift
lever into another gear. See
Shifting
Out of Park on page 9‑26.
R (Reverse): Use this gear to
back up.
Notice: Shifting to R (Reverse)
while the vehicle is moving
forward could damage the
transmission. The repairs would
not be covered by the vehicle
warranty. Shift to R (Reverse)
only after the vehicle is stopped.
To rock the vehicle back and forth to
get out of snow, ice, or sand without
damaging the transmission, see If
the Vehicle is Stuck on page 9‑11. N (Neutral):
In this position, the
engine does not connect with
the wheels. To restart the engine
when the vehicle is already moving,
use N (Neutral) only. Also, use
N (Neutral) when the vehicle is
being towed.
{WARNING
Shifting into a drive gear while the
engine is running at high speed
is dangerous. Unless your foot
is firmly on the brake pedal, the
vehicle could move very rapidly.
You could lose control and hit
people or objects. Do not shift
into a drive gear while the engine
is running at high speed.
Notice: Shifting out of P (Park)
or N (Neutral) with the engine
running at high speed may
damage the transmission.
The repairs would not be covered
by the vehicle warranty. Be sure
the engine is not running at high
speed when shifting the vehicle.

Vehicle Care 10-59
.Replacement tires or wheels do
not match the original equipment
tires or wheels. Tires and wheels
other than those recommended
could prevent the TPMS from
functioning properly. SeeBuying
New Tires on page 10‑64.
.Operating electronic devices or
being near facilities using radio
wave frequencies similar to the
TPMS could cause the TPMS
sensors to malfunction.
If the TPMS is not functioning
properly it cannot detect or signal a
low tire condition. See your dealer
for service if the TPMS malfunction
light and DIC message comes on
and stays on.
TPMS Sensor Matching
Process
Each TPMS sensor has a unique
identification code. The identification
code needs to be matched to a
new tire/wheel position after rotating
the vehicle’ s tires or replacing
one or more of the TPMS sensors.
The TPMS sensor matching process
should also be performed after
replacing a spare tire with a road
tire containing the TPMS sensor.
The malfunction light and the DIC
message should go off at the next
ignition cycle. The sensors are
matched to the tire/wheel positions,
using a TPMS relearn tool, in the
following order: driver side front tire,
passenger side front tire, passenger
side rear tire, and driver side rear.
See your dealer for service or to
purchase a relearn tool. There are two minutes to match
the first tire/wheel position, and
five minutes overall to match all
four tire/wheel positions. If it takes
longer, the matching process stops
and must be restarted.
The TPMS sensor matching
process is:
1. Set the parking brake.
2. Turn the ignition to ON/RUN with
the engine off.
3. Use the MENU button to select the Vehicle Information Menu
in the Driver Information
Center (DIC).
4. Use the thumbwheel to scroll to the Tire Pressure Menu Item
screen.
