A WORD ABOUT YOUR KEYS
The keys for your new vehicle are enclosed in a plastic
bag with the key code number on it. If you received your
keys without the bag, ask your authorized dealer to give
you the number. The key code can also be obtained by
your authorized dealer from your vehicle invoice.

1. The “Automatic Door Locks” feature is enabled.
2. The transmission is in gear.
3. All doors are closed.
4. The throttle is pressed.
5. The vehicle speed is above 15 mph (24 km/h).
6. The doors were not previously locked using the power
door lock switch or Remote Keyless Entry (RKE)
transmitter.
Automatic Door Locks Programming
The “Automatic Door Locks” feature can be enabled or
disabled as follows:
1. Close all doors and place the key in the ignition.
2. Cycle the ignition switch between LOCK and ON and
then back to LOCK four times ending up in the LOCK
position.
3. Depress the power door LOCK switch to lock the
doors.
4. A single chime will indicate the completion of the
programming.
5. Repeat these steps if you want to return this feature to

34 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

Using Electronic Speed Control On Hills
NOTE:The Electronic Speed Control system maintains
speed up and down hills. A slight speed change on
moderate hills is normal.
On steep hills, a greater speed loss or gain and/or more
frequent downshifts (auto transmission only) may occur
so it may be preferable to drive without Electronic Speed
Control.
ELECTRICAL POWER OUTLET
There are two 12-Volt (DC) auxiliary power outlets that can
provide up to 160 Watts (13 Amps) of current for accesso-
ries designed for use with the standard power outlet
adapters. The power outlet, located in the lower portion of
the instrument panel, has a snap-on plastic cap so that it
can be covered when not in use. When the optional cigar
lighter heating element is used in the left-side power outlet,
it heats when pushed in and pops out automatically when ready for use.
To preserve the heating element, do not
hold the lighter in the heating position.
NOTE: Do not exceed the maximum power of 160 Watts
(13 Amps) at 12-Volts.
The left-side power outlet is powered when the key is in
the ON or ACC positions.

21. Odometer / Trip Odometer Reset Button
Press this button to change the display from odometer to
either of the two trip odometer settings. Trip A or Trip B
will appear when in the trip odometer mode. Press and
hold the button for two seconds to reset the trip odometer
to 0 miles or kilometers. The odometer must be in trip
mode to reset.
22. Shift Lever Indicator
The Shift Lever Indicator is self-contained within the
instrument cluster. It displays the gear position of the
automatic transmission.
23. Tire Pressure Monitoring Telltale LightEach tire, including the spare (if provided),
should be checked monthly, when cold and
inflated to the inflation pressure recommended
by the vehicle manufacturer on the vehicle placard or tire
inflation pressure label. (If your vehicle has tires of a
different size than the size indicated on the vehicle placard or tire inflation pressure label, you should deter-
mine the proper tire inflation pressure for those tires.)
As an added safety feature, your vehicle has been
equipped with a Tire Pressure Monitoring System
(TPMS) that illuminates a low tire pressure telltale when
one or more of your tires is significantly under-inflated.
Accordingly, when the low tire pressure telltale illumi-
nates, you should stop and check your tires as soon as
possible, and inflate them to the proper pressure. Driving
on a significantly under-inflated tire causes the tire to
overheat and can lead to tire failure. Under-inflation also
reduces fuel efficiency and tire tread life, and may affect
the vehicle’s handling and stopping ability.
Please note that the TPMS is not a substitute for proper
tire maintenance, and it is the driver ’s responsibility to
maintain correct tire pressure, even if under-inflation has
not reached the level to trigger illumination of the TPMS
low tire pressure telltale.

NOTE:If the indicator message illuminates when you
start the vehicle, the oil change indicator system did not
reset. If necessary repeat this procedure.
25. Malfunction Indicator Light (MIL) The Malfunction Indicator Light (MIL) is a part of
an Onboard Diagnostic System called OBD II that
monitors engine and automatic transmission con-
trol systems. The light will illuminate when the ignition
is in the ON position, before engine start. If the bulb does
not come on when turning the key from OFF to ON, have
the condition checked promptly.
Certain conditions such as a loose or missing gas cap,
poor quality fuel, etc. may illuminate the light after
engine start. The vehicle should be serviced if the light
stays on through several typical driving styles. In most
situations, the vehicle will drive normally and will not
require towing.

Automatic Compass Calibration
The self-calibrating feature of the compass eliminates the
need to calibrate the compass for normal conditions.
During a short initial period, the compass may appear
erratic and the CAL symbol will appear (blinking) on the
display. After the vehicle has completed at least one
complete circle under 5 mph (8 km/h) in an area free
from large metal objects, calibration will be complete
when the CAL symbol is extinguished.
After initial calibration, the compass will continue to
automatically update this calibration whenever the ve-
hicle is in motion.
Manual Compass Calibration
NOTE: Before attempting a manual compass calibra-
tion, the engine must be running and the transmission
in the PARK position (if equipped).If the compass appears erratic or inaccurate and the
variance has been properly set, you may wish to manu-
ally recalibrate the compass. To manually calibrate the
compass:
1. First enter the variance mode. Press and hold the left
button (located on the instrument cluster) for approxi-
mately 10 seconds to enter the variance mode, and
release the button when the VAR (Compass Variance)
symbol appears.
2. The current variance value will also be displayed.
Once in the variance mode, it is necessary to release the
button, and then press and hold it again (approximately
10 seconds) until CAL is displayed (solid, not blinking).

274 STARTING AND OPERATING

Tip Start Feature — Automatic Transmission Only
Turn the ignition switch to the START position and
release it as soon as the starter engages. The starter motor
will continue to run, but will automatically disengage
itself when the engine is running. If the engine fails to
start, the starter will disengage automatically in 10 sec-
onds. If this occurs, turn the ignition switch to the LOCK
position, wait 10 to 15 seconds, then repeat the “Normal
Starting” procedure.
Extreme Cold Weather (below –20°F or –29°C)
To ensure reliable starting at these temperatures, use of
an externally-powered electric engine block heater (avail-
able from your authorized dealer) is recommended.
If Engine Fails to Start

If the engine shows no sign of starting after two 15–
second periods of cranking with the accelerator pedal
held to the floor, repeat the “Normal Starting” or “Ex-
treme Cold Weather” procedures.
With Tip Start — Automatic Transmission Only
If the engine fails to start after you have followed the
“Normal Starting” or “Extreme Cold Weather” proce-
dures, it may be flooded. To clear any excess fuel, push
the accelerator pedal all the way to the floor and hold it.
Then, turn the ignition switch to the START position and
release it as soon as the starter engages. The starter motor
will disengage automatically in 10 seconds. Once this
occurs, release the accelerator pedal, turn the ignition
switch to the LOCK position, wait 10 to 15 seconds, then
repeat the “Normal Starting” procedure.

If the transmission overheats, a “HOTOIL” message will
be displayed in the odometer and a chime will sound.
Overdrive can be locked out by pressing the O/D OFF
switch located on the center console. The “O/D OFF
Indicator Light” (on the switch) will illuminate to show
that the switch has been activated. When the indicatorlight is on, Overdrive is locked out. Pressing the switch a
second time restores the Overdrive function. The lockout
feature is useful when towing a trailer or carrying a
heavy load.
2 (Second)
This range is used for moderate grades and to assist
braking on dry pavement or in mud and snow. The
vehicle begins from a stop in low gear with automatic
upshift to second gear. The vehicle will not shift into
third gear.
1 (First)
This range is used for hard pulling at low speeds in mud,
sand, snow, or on steep grades. The vehicle begins and
stays in low gear with no upshift. This gear provides
engine compression braking at low speeds.
