CAUTION:
Don't keep driving if the oil pressure is low. If
you do, your engine can become so hot that it
catches fire. You or others could be burned.
Check your oil as soon as possible and have your
vehicle serviced.
NOTICE:
Damage to your engine from neglected oil
problems can be costly and is not covered by
your warranty.
Security Light
This light comes on to
remind you to arm your
theft
-deterrent system. If it
comes on and stays on when
your ignition is on, there
may be a problem with your
theft
-deterrent system.
See ªUniversal Theft
-Deterrentº and ªPASS-Key
Systemº in the Index.
Check Gages Warning Light
This light will come on
briefly when you are
starting the engine. If the
light comes on and stays on
while you are driving, check
your gages to see if they are
in the warning areas.

This light can come on for the following reasons:

Low Oil Pressure

High Coolant Temperature

High or Low Battery Voltage

Low Fuel Level
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
fill 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.

To adjust the HUD so you can see it properly:
1. Start your engine and slide the HUD dimmer control
all the way up.
The brightness of the HUD image is determined by
the ambient light conditions in the direction your
vehicle is facing and where you have the HUD
dimmer control set. If you are facing a dark object or
a heavily shaded area, your HUD may anticipate that
you are entering a dark area and may begin to dim.
2. Adjust the seat to your driving position. If you
change your seat position later, you may have to
re
-adjust your HUD.
3. Press the DISPLAY rocker switch up or down to
center the HUD image in your view.
NOTE: The HUD image can only be adjusted up and
down, not side
-to-side.
4. Slide the dimmer control downward until the HUD
image is no brighter than necessary. To turn HUD
off, slide the switch to OFF.
If the sun comes out or it becomes cloudy, you may need
to adjust the HUD brightness again using the dimmer
control. Polarized sunglasses could make the HUD
image harder to see.To change from English to metric units, push the E/M
button located to the right of the steering wheel.
Clean the inside of the windshield as needed to remove
any dirt or film that reduces the sharpness or clarity of
the HUD image.
To clean the HUD, spray household glass cleaner on a
soft, clean cloth. Wipe the HUD lens gently, then dry it.
Do not spray cleaner directly on the lens because the
cleaner could leak into the unit.
If the ignition is on and you can't see the HUD image,
check to see if:

something is covering the HUD unit.

the HUD dimmer control is adjusted properly.

the HUD image is adjusted to the proper height.

ambient light (in the direction your vehicle is facing)
is low.

a fuse is blown. See ªFuses and Circuit Breakersº in
the Index.
Keep in mind that your windshield is part of the HUD
system. If you ever have to have your windshield
replaced, be sure to get one that is designed for HUD or
your HUD image may look blurred and out of focus.

will be displayed. See ªMatching Transmitter(s) To Your
Vehicleº in the Index for more information.
TIRE TRAINING: The Tire Pressure Monitor (TPM)
operates with battery-powered sensors that are located
inside the valve stems on each tire. Each sensor has a
unique ID code so the vehicle knows the tire location of
the sensor. When the vehicle reaches a speed of greater
than 15 mph (24 km/h), the sensors begin to send the
tire pressure readings to a receiver inside the vehicle.
These readings are displayed when using the GAGES
button on the DIC. If you are unable to display your tire
pressures while the vehicle speed is greater than 15 mph
(24 km/h), you may need to have your sensor ID codes
learned by the vehicle. See your dealer.

off. Then start the engine again to reset the system. If
the message stays on, or comes back on again while you
