If the light stops flashing and remains on steady,
see ªIf the Light Is On Steadyº following.
If the light continues to flash, when it is safe to do so,
stop the vehicle. Find a safe place to park your vehicle.
Turn the key off, wait at least 10 seconds and restart the
engine. If the light remains on steady, see ªIf the Light
Is On Steadyº following. If the light is still flashing,
follow the previous steps, and drive the vehicle to your
dealer or qualified service center for service.
If the Light Is On Steady
You may be able to correct the emission system
malfunction by considering the following:
Did you recently put fuel into your vehicle?
If so, reinstall the fuel cap, making sure to fully install
the cap. See ªFilling Your Tankº in the Index. The
diagnostic system can determine if the fuel cap has been
left off or improperly installed. A loose or missing fuel
cap will allow fuel to evaporate into the atmosphere.
A few driving trips with the cap properly installed
should turn the light off.Did you just drive through a deep puddle of water?
If so, your electrical system may be wet. The condition
will usually be corrected when the electrical system
dries out. A few driving trips should turn the light off.
Have you recently changed brands of fuel?
If so, be sure to fuel your vehicle with quality fuel
(see ªFuelº in the Index). Poor fuel quality will
cause your engine not to run as efficiently as designed.
You may notice this as stalling after start
-up, stalling
when you put the vehicle into gear, misfiring, hesitation
on acceleration or stumbling on acceleration. (These
conditions may go away once the engine is warmed up.)
This will be detected by the system and cause the light
to turn on.
If you experience one or more of these conditions,
change the fuel brand you use. It will require at least
one full tank of the proper fuel to turn the light off.
If none of the above steps have made the light turn off,
have your dealer or qualified service center check the
vehicle. Your dealer has the proper test equipment and
diagnostic tools to fix any mechanical or electrical
problems that may have developed.

Fuel Gage
Your fuel gage tells you
about how much fuel
you have left when the
ignition is on.
When the needle approaches the red zone, RESERVE
FUEL will appear on the Driver Information Center
(DIC) display. When the needle approaches the ªE,º
LOW FUEL will appear on the display. At this time,
you still have a little fuel left, but you should get
more soon.
Press RESET to acknowledge a DIC message(s).
Pressing RESET will also turn off a DIC message but
the LOW FUEL message will come on again in
10 minutes if you have not added fuel to the vehicle.Here are four things that some owners ask about.
All these things are normal and do not indicate that
anything is wrong with the fuel gage.
At the gas station, the gas pump shuts off before
the gage reads FULL (F).
It takes more (or less) fuel to fill up than the gage
reads. For example, the gage reads half full, but it
took more (or less) than half of the tank's capacity to
fit it.
The gage pointer may move while cornering, braking
or speeding up.
The gage may not indicate EMPTY (E) when the
ignition is turned off.
You can use the Driver Information Center (DIC) to
display more detailed fuel information. Each time you
press FUEL, one of the following will appear in the
Driver Information Center (DIC).
AVERAGE: The fuel economy calculated for the
current tank of fuel, or since you last reset the display.
INST: The fuel economy calculated for your current
driving conditions.
RANGE: The distance you can drive before refueling.
BLANK: The fuel gage is displayed alone.

You should reset the fuel information display every
time you refuel. To reset the display, press FUEL until
AVERAGE appears. Then, press RESET on the Driver
Information Center (DIC).
Head-Up Display (Option)
CAUTION:
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's dark outside.
Be sure to keep the HUD image dim and placed
low in your field of view.
If your vehicle is equipped with the Head-Up Display
(HUD), you can see some of the driver information that
appears on your instrument panel cluster.The information may be displayed in English or metric
units and appears as an image focused out toward the
front of your vehicle. The HUD consists of the
following information:
Speedometer
Turn Signal Indicators
High
-Beam Indicator Symbol
Tachometer
Oil, Temperature and Fuel Gages
Shift Light (Performance SHIFT Light)
This light is used for performance driving to indicate
that the vehicle's best performance level has been
reached to shift the transmission into the next higher
gear. The SHIFT light will display at an engine
speed of about 5,750 rpm, just prior to reaching the
engine fuel cut
-off mode. To better understand the
vehicle's power curves, see ªCapacities and
Specificationsº in the Index.

If the outside temperature goes up, the displayed
temperature will not change until:
The vehicle's speed is above 16 mph (26 km/h) for
one and a half minutes.
The vehicle's speed is above 45 mph (72 km/h) for
one minute.
These delays help prevent false readings. If the
temperature goes down, the outside temperature display
is updated immediately.
If the vehicle has been turned off for more than three
hours, the current outside temperature will be shown
when you start the vehicle. If it has been turned off for
less than three hours, the temperature will be recalled
from the previous vehicle operation.
Inside Temperature Sensor
This sensor is located to the left of the ignition switch.
The automatic climate control system uses this sensor to
receive information, so if you block or cover it, the
system will not function properly.Air Conditioning
On very hot days, the vehicle will cool down more
quickly and economically if you open the windows
long enough to let hot inside air escape. Then keep the
windows closed in order to allow the air conditioning to
work best. Maximum cooling will occur when the
recirculate setting is operating, airflow direction is in the
upper mode, and the temperature control knob (on a
manual climate control system) is turned all the way to
the blue area. These settings will be selected by the
automatic electronic dual climate control system if
operating in AUTO when maximum cooling is required.
When the air conditioning is on, you may sometimes
notice slight changes in the vehicle's engine
performance and power. This is normal. The system is
designed to help fuel economy while maintaining the
desired cooling level.
The air conditioning removes moisture from the air, so
you may notice water dripping from under the vehicle
when it is idling or after it has been turned off.
This is normal.

Loading Your Vehicle
Two labels on your vehicle show how much weight it
may properly carry. The Tire
-Loading Information
label found on the rear edge of the driver's door tells
you the proper size, speed rating and recommended
inflation. It also gives you important information about
the number of people that can be in your vehicle and the
total weight that you can carry. This weight is called
Vehicle Capacity Weight and includes the weight of all
occupants, cargo and all non
-factory-installed options.
The other label is the Certification label, found on
the rear edge of the driver's door. It tells you the
gross weight capacity of your vehicle, called the Gross
Vehicle Weight Rating (GVWR). The GVWR includes
the weight of the vehicle, all occupants, fuel and cargo.
Never exceed the GVWR for your vehicle, or the Gross
Axle Weight Rating (GAWR) for either the front or
rear axle.
And, if you do have a heavy load, you should spread
it out. Don't carry more than 100 lbs. (45 kg) in the
rear area.
