Notice:Modifications made to the
engine, transmission, exhaust,
intake, or fuel system of the
vehicle or the replacement of
the original tires with other
than those of the same Tire
Performance Criteria (TPC) can
affect the vehicle's emission
controls and can cause this light
to come on. Modifications to
these systems could lead to
costly repairs not covered by
the vehicle warranty. This could
also result in a failure to
pass a required Emission
Inspection/Maintenance test.
See Accessories and
Modifications on page 10‑3.
This light comes on during a
malfunction in one of two ways:
Light Flashing: A misfire condition
has been detected. A misfire
increases vehicle emissions and
could damage the emission control
system on the vehicle. Diagnosis
and service might be required. To prevent more serious damage to
the vehicle:
.Reduce vehicle speed.
.Avoid hard accelerations.
.Avoid steep uphill grades.
.If towing a trailer, reduce the
amount of cargo being hauled as
soon as it is possible.
If the light continues to flash, stop
and park the vehicle. Turn the
vehicle off, wait at least 10 seconds,
and restart the engine. If the light is
still flashing, follow the previous
steps and see your dealer for
service as soon as possible.
Light On Steady: An emission
control system malfunction has
been detected on the vehicle.
Diagnosis and service might be
required. The following may correct an
emission system malfunction:
.Check that the fuel cap is fully
installed. See
Filling the Tank on
page 9‑42. The diagnostic
system can determine if the
fuel cap has been left off or
improperly installed. A loose or
missing fuel cap allows fuel to
evaporate into the atmosphere.
A few driving trips with the cap
properly installed should turn
the light off.
.Check that good quality fuel
is used. Poor fuel quality
causes the engine not to run as
efficiently as designed and may
cause stalling after start-up,
stalling when the vehicle is
changed into gear, misfiring,
hesitation on acceleration,
or stumbling on acceleration.
These conditions might go away
once the engine is warmed up.

Changer on page 6‑2 for more
information.
Front Fog Lamp Light
The fog lamp light comes on when
the fog lamps are in use. The light goes out when the fog
lamps are turned off. See
Fog
Lamps on page 6‑5 for more
information.
Cruise Control Light
This light comes on whenever the
cruise control is set.
The light goes out when the cruise
control is turned off. See Cruise
Control on page 9‑32 for more
information.
Information Displays
Driver Information Center
(DIC) (With DIC Buttons)
If your vehicle has DIC buttons,
the information below explains the
operation of this system.
The DIC displays information about
your vehicle. It also displays
warning messages if a system
problem is detected.
All messages will appear in the
DIC display located at the top of
the instrument panel cluster.
The DIC comes on when the ignition
is on. After a short delay, the DIC
will display the information that was
last displayed before the engine

Head-Up Display (HUD)
{WARNING
If the HUD image is too bright or
too high in your field of view, it
may take you more time to see
things you need to see when it is
dark outside. Be sure to keep the
HUD image dim and placed low in
your field of view.
For vehicles with the Head-Up
Display (HUD), some information
concerning the operation of the
vehicle is projected onto the
windshield. This includes the
speedometer reading, rpm reading,
transmission position, outside air
temperature, the manual mode gear
range, and a brief display of the current radio station, including XM
information or CD track. It will also
display turn-by-turn navigation
information if the vehicle has a
navigation radio. The images are
projected by the HUD lens located
on the driver side of the instrument
panel.
The HUD information can be
displayed in one of three languages,
English, French, or Spanish.
The speedometer reading and
other numerical values can be
displayed in either English or
metric units.
The language selection and the
units of measurement are changed
through the trip computer in the
Driver Information Center (DIC).
See
Vehicle Personalization
(With DIC Buttons) on page 5‑46.
HUD Display on the Vehicle
Windshield
The HUD information appears as an
image focused out toward the front
of the vehicle.
When the ignition key is turned to
ON/RUN, the HUD will display an
introductory message for a short
time, until the HUD is ready.
