Highbeam On Light
This light comes on whenthe high-beam headlampsare in use.
SeeHeadlamp High/Low-Beam Changer on page 4-6for more information.
Fuel Gage
The fuel gage showsapproximately how muchfuel is in the tank. Itworks only when theengine is on.
An arrow on the fuel gage indicates the side of thevehicle the fuel door is on.
If the fuel supply gets low, the FUEL LEVEL LOWmessage appears in the Driver Information Center anda single chime sounds. SeeDIC Warnings andMessages on page 4-67for more information.
Here are a few situations that may occur with the fuelgage. All of these situations are normal and do notindicate that anything is wrong with the fuel gage:
•At the gas station the gas pump shuts off before the
gage reads full.
•The gage may change when the vehicle is turning,
stops quickly or accelerates quickly.
•It takes a little more or less fuel to fill the tank than
the gage indicated. For example, the gage mayhave indicated that the tank was half full, butit actually took a little more or less than half thetank’s capacity to fill the tank.
Driver Information Center (DIC)
The Driver Information Center (DIC) gives you thestatus of many of your vehicle’s systems. The DIC isalso used to display warning/status messages. Allmessages will appear in the DIC display located at thebottom of the instrument panel cluster, below thetachometer and speedometer. The DIC buttons arelocated on the instrument panel, to the left of thesteering wheel.

Keep a record with all parts receipts and list the mileageand the date of any service work performed. SeeMaintenance Record on page 7-12.
Adding Equipment to the Outside of
the Vehicle
Things added to the outside of the vehicle can affect theairflow around it. This can cause wind noise and canaffect fuel economy and windshield washer performance.Check with your dealer/retailer before adding equipmentto the outside of the vehicle.
Fuel
Use of the recommended fuel is an important part of theproper maintenance of this vehicle. To help keep theengine clean and maintain optimum vehicleperformance, we recommend the use of gasolineadvertised as TOP TIER Detergent Gasoline.
Look for the TOP TIER label on the fuel pump to ensuregasoline meets enhanced detergency standardsdeveloped by auto companies. A list of marketersproviding TOP TIER Detergent Gasoline can be foundat www.toptiergas.com.
Gasoline Octane
Use premium unleaded gasoline with a posted octanerating of 91 or higher. You can also use regularunleaded gasoline rated at 87 octane or higher, but thevehicle’s acceleration could be slightly reduced, anda slight audible knocking noise, commonly referred to asspark knock, might be heard. If the octane is lessthan 87, you might notice a heavy knocking noise whenyou drive.

Filling the Tank
{WARNING:
Fuel vapor burns violently and a fuel fire can
cause bad injuries. To help avoid injuries to you
and others, read and follow all the instructions on
the fuel pump island. Turn off the engine when
refueling. Do not smoke near fuel or when
refueling the vehicle. Do not use cellular phones.
Keep sparks, flames, and smoking materials away
from fuel. Do not leave the fuel pump unattended
when refueling the vehicle. This is against the law
in some places. Do not re-enter the vehicle while
pumping fuel. Keep children away from the fuel
pump; never let children pump fuel.
The tethered fuel cap is located behind a hinged fueldoor on the driver side of the vehicle.
To open the fuel door, push the rearward center edge inand release and it will open.

To remove the fuel cap, turn it slowly counterclockwise.The fuel cap has a spring in it; if the cap is releasedtoo soon, it will spring back to the right.
While refueling, hang the tethered fuel cap from thehook on the fuel door.
{WARNING:
Fuel can spray out on you if you open the fuel cap
too quickly. If you spill fuel and then something
ignites it, you could be badly burned. This spray
can happen if the tank is nearly full, and is more
likely in hot weather. Open the fuel cap slowly and
wait for any hiss noise to stop. Then unscrew the
cap all the way.
Be careful not to spill fuel. Do not top off or overfill thetank and wait a few seconds after you have finishedpumping before removing the nozzle. Clean fuelfrom painted surfaces as soon as possible. SeeWashing Your Vehicle on page 6-95.
When replacing the fuel cap, turn it clockwise until itclicks. Make sure the cap is fully installed. Thediagnostic system can determine if the fuel cap has
been left off or improperly installed. This would allowfuel to evaporate into the atmosphere. SeeMalfunctionIndicator Lamp on page 4-57.
The TIGHTEN GAS CAP message displays on theDriver Information Center (DIC) if the fuel cap isnot properly installed. SeeDIC Warnings and Messageson page 4-67for more information.
{WARNING:
If a fire starts while you are refueling, do not
remove the nozzle. Shut off the flow of fuel by
shutting off the pump or by notifying the station
attendant. Leave the area immediately.
Notice:If you need a new fuel cap, be sure to getthe right type. Your dealer/retailer can get onefor you. If you get the wrong type, it may not fitproperly. This may cause the malfunction indicatorlamp to light and may damage the fuel tank andemissions system. SeeMalfunction Indicator Lampon page 4-57.

Filling a Portable Fuel Container
{WARNING:
Never fill a portable fuel container while it is in the
vehicle. Static electricity discharge from the
container can ignite the fuel vapor. You can be
badly burned and the vehicle damaged if this
occurs. To help avoid injury to you and others:
•Dispense fuel only into approved containers.
•Do not fill a container while it is inside a
vehicle, in a vehicle’s trunk, pickup bed, or onany surface other than the ground.
•Bring the fill nozzle in contact with the inside
of the fill opening before operating the nozzle.Contact should be maintained until the fillingis complete.
•Do not smoke while pumping fuel.
•Do not use a cellular phone while
pumping fuel.
Checking Things Under
the Hood
{WARNING:
An electric fan under the hood can start up and
injure you even when the engine is not running.
Keep hands, clothing, and tools away from any
underhood electric fan.
{WARNING:
Things that burn can get on hot engine parts and
start a fire. These include liquids like fuel, oil,
coolant, brake fluid, windshield washer and other
fluids, and plastic or rubber. You or others could
be burned. Be careful not to drop or spill things
that will burn onto a hot engine.
