To decrease speed while the Electronic Speed Control is
set, push down and hold the SET DECEL lever. If the
lever is continually held in the SET DECEL position, the
set speed will continue to decrease until the lever is
released. Release the lever when the desired speed is
reached, and the new set speed will be established.
Tapping the SET DECEL lever once will result ina1mph
(2 km/h) decrease in set speed. Each subsequent tap of
the lever results in a decrease of 1 mph (2 km/h).
To Accelerate for Passing
Press the accelerator as you would normally. When the
pedal is released, the vehicle will return to the set speed.
NOTE:The Electronic Speed Control system maintains
speed up and down hills. A slight speed change on
moderate hills is normal.Your vehicle may experience a downshift (automatic
transmissions only) while climbing uphill or descending
downhill. This downshift is necessary to maintain vehicle
set speed.
On steep hills a greater speed loss or gain may occur so
it may be preferable to drive without Electronic Speed
Control.
WARNING!
Electronic Speed Control can be dangerous where the
system cannot maintain a constant speed. Your ve-
hicle could go too fast for the conditions, and you
could lose control and have a collision. Do not use
Electronic Speed Control in heavy traffic or on roads
that are winding, icy, snow-covered or slippery.

17. Engine Temperature Warning Light
This light warns of an overheated engine condi-
tion. As temperatures rise and the gauge ap-
proachesH,this indicator will illuminate and a
single chime will sound after reaching a set threshold.
Further overheating will cause the temperature gauge to
passH,the indicator will continuously flash and a
continuous chime will occur until the engine is allowed
to cool.
If the light turns on while driving, safely pull over and
stop the vehicle. If the A/C system is on, turn it off. Also,
shift the transmission into NEUTRAL and idle the ve-
hicle. If the temperature reading does not return to
normal, turn the engine off immediately and call for
service. Refer to “If Your Engine Overheats” in “What To
Do In Emergencies” for further information.
For vehicles equipped with a premium cluster this indi-
cator will display in the Electronic Vehicle InformationCenter (EVIC). Refer to ”Electronic Vehicle Information
Center (EVIC) — If Equipped” for further information.
18. Shift Lever Indicator
The Shift Lever Indicator is self-contained within the
instrument cluster. It displays the gear position of the
automatic transmission.
NOTE:In vehicles with 4.7L or 5.7L engines, the highest
available transmission gear is displayed in the lower
right corner of the Electronic Vehicle Information Center
(EVIC) whenever the Electronic Range Select (ERS) fea-
ture is active. Use the +/- selector on the shift lever to
activate ERS. Refer to “Automatic Transmission” in

beam. Push the multifunction lever forward to
switch the headlights to high beam, and pull toward
yourself (normal position) to return to low beam.
21. Voltmeter
When the engine is running, the gauge indicates the
electrical system voltage. The pointer should stay within
the normal range if the battery is charged. If the pointer
moves to either extreme left or right and remains there
during normal driving, the electrical system should be
serviced.
NOTE:The voltmeter may show a gauge fluctuation at
various engine temperatures. This cycling operation iscaused by the post-heat cycle of the intake manifold
heater system. The number of cycles and the length of the
cycling operation is controlled by the engine control
module. Post-heat operation can run for several minutes,
and then the electrical system and voltmeter needle will
stabilize.
22. Cargo Light
The cargo light will illuminate when the cargo
light is activated by pressing the cargo light
button on the headlight switch.
23. Brake Warning Light
This light monitors various brake functions,
including brake fluid level and parking brake
application. If the brake light turns on, it may
indicate that the parking brake is applied, that
the brake fluid level is low, or that there is a problem with
the Anti-lock Brake System reservoir.

UNDERSTANDING YOUR INSTRUMENT PANEL 215

If the light remains on when the parking brake has been
disengaged, and the fluid level is at the full mark on the
master cylinder reservoir, it indicates a possible brake
hydraulic system malfunction or that a problem with the
Brake Booster has been detected by the Anti-Lock Brake
System (ABS) / Electronic Stability Program (ESP) sys-
tem. In this case, the light will remain on until the
condition has been corrected. If the problem is related to
the brake booster, the ABS pump will run when applying
the brake and a brake pedal pulsation may be felt during
each stop.
The dual brake system provides a reserve braking capac-
ity in the event of a failure to a portion of the hydraulic
system. A leak in either half of the dual brake system is
indicated by the Brake Warning Light, which will turn on
when the brake fluid level in the master cylinder has
dropped below a specified level.
The light will remain on until the cause is corrected.NOTE:The light may flash momentarily during sharp
cornering maneuvers, which change fluid level condi-
tions. The vehicle should have service performed, and
the brake fluid level checked.
If brake failure is indicated, immediate repair is neces-
sary.
WARNING!
Driving a vehicle with the red brake light on is
dangerous. Part of the brake system may have failed.
It will take longer to stop the vehicle. You could have
a collision. Have the vehicle checked immediately.
Vehicles equipped with the ABS, are also equipped with
Electronic Brake Force Distribution (EBD). In the event of
an EBD failure, the Brake Warning Light will turn on
along with the ABS Light. Immediate repair to the ABS
system is required.

Operation of the Brake Warning Light can be checked by
turning the ignition switch from the OFF position to the
ON/RUN position. The light should illuminate for ap-
proximately two seconds. The light should then turn off
unless the parking brake is applied or a brake fault is
detected. If the light does not illuminate, have the light
inspected by an authorized dealer.
The light also will turn on when the parking brake is
applied with the ignition switch in the ON/RUN posi-
tion.
NOTE:This light shows only that the parking brake is
applied. It does not show the degree of brake application.
24. Oil Pressure Warning Light
This light indicates low engine oil pressure. The
light should turn on momentarily when the engine
is started. If the light turns on while driving, stop thevehicle and shut off the engine as soon as possible. A
chime will sound for four minutes when this light turns
on.
Do not operate the vehicle until the cause is corrected.
This light does not indicate how much oil is in the engine.
The engine oil level must be checked under the hood.
For vehicles equipped with a premium cluster this indi-
cator will display in the Electronic Vehicle Information
Center (EVIC). Refer to ”Electronic Vehicle Information
Center (EVIC) — If Equipped” for further information.
25. Tire Pressure Monitoring Telltale Light
Each 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
4
UNDERSTANDING YOUR INSTRUMENT PANEL 217

tires or wheels on your vehicle, to ensure that the
replacement or alternate tires and wheels allow the TPMS
to continue to function properly.
CAUTION!
The TPMS has been optimized for the original
equipment tires and wheels. TPMS pressures and
warning have been established for the tire size
equipped on your vehicle. Undesirable system opera-
tion or sensor damage may result when using re-
placement equipment that is not of the same size,
type, and/or style. Aftermarket wheels can cause
sensor damage. Do not use tire sealant from a can, or
balance beads if your vehicle is equipped with a
TPMS, as damage to the sensors may result.
NOTE:The TPMS telltale is also accompanied by a
“Low Tire” message in the odometer (Base Cluster), or inthe Electronic Vehicle Information Center (EVIC) screen
indicating “Low Tire” for EVIC enabled clusters.
26. Malfunction Indicator Light (MIL)
The Malfunction Indicator Light (MIL) is part of
an onboard diagnostic (OBDII) system which
monitors the emissions and engine control sys-
tem. If the vehicle is ready for emissions testing, the light
will come on when the ignition is first turned on and
remain on, as a bulb check, until the engine is started. If
the vehicle is not ready for emissions testing the light will
come on when the ignition is first turned on and remain
on for 15 seconds, then blink for 5 seconds, and remain
on until the vehicle is started. If the bulb does not come
on during starting, have the condition investigated
promptly.
If this light comes on and remains on while driving, it
suggests a potential engine control problem and the need
for system service.

UNDERSTANDING YOUR INSTRUMENT PANEL 219

Although your vehicle will usually be drivable and not
need towing, see your authorized dealer for service as
soon as possible.
CAUTION!
Prolonged driving with the MIL on could cause
damage to the engine control system. It also could
affect fuel economy and drivability. If the MIL is
flashing, severe catalytic converter damage and
power loss will soon occur. Immediate service is
required.
WARNING!
A malfunctioning catalytic converter, as referenced
above, can reach higher temperatures than in normal
operating conditions. This can cause a fire if you
drive slowly or park over flammable substances such
as dry plants or wood or cardboard, etc. This could
result in death or serious injury to the driver, occu-
pants or others.
27. Airbag Warning Light
This light will turn on for four to eight seconds
as a bulb check when the ignition switch is first
turned to ON/RUN. If the light is either not on
during starting, stays on, or turns on while
driving, then have the system inspected at an authorized
dealer as soon as possible. Refer to “Occupant Restraints”
in “Things To Know Before Starting Your Vehicle” for
further information.
