Warning symbols on your vehicle
When you see this symbol, it is
imperative that you consult the
relevant section of this guide before
touching or attempting adjustment
of any kind.
Protecting the environment
We must all play our part in
protecting the environment. Correct
vehicle usage and the authorized
disposal of waste, cleaning and
lubrication materials are significant
steps towards this aim. Information in this respect is highlighted in this
guide with the tree symbol.
CALIFORNIA Proposition 65 Warning
WARNING:Engine exhaust, some of its constituents, and
certain vehicle components contain or emit chemicals known to
the State of California to cause cancer and birth defects or other
reproductive harm. In addition, certain fluids contained in vehicles and
certain products of component wear contain or emit chemicals known
to the State of California to cause cancer and birth defects or other
reproductive harm.
PERCHLORATE MATERIAL
Certain components of this vehicle such as airbag modules, seat belt
pretensioners, and button cell batteries may contain Perchlorate Material
– Special handling may apply for service or vehicle end of life disposal.
See www.dtsc.ca.gov/hazardouswaste/perchlorate.
BREAKING-IN YOUR VEHICLE
Your vehicle does not need an extensive break-in. Try not to drive
continuously at the same speed for the first 1,000 miles (1,600 km) of
new vehicle operation. Vary your speed frequently in order to give the
moving parts a chance to break in.
Drive your new vehicle at least 1,000 miles (1,600 km) before towing a
trailer. For more detailed information about towing a trailer, refer to
Trailer towingin theTires, Wheels and Loadingchapter.
Do not add friction modifier compounds or special break-in oils since these
additives may prevent piston ring seating. SeeEngine oilin the
Maintenance and Specificationschapter for more information on oil usage.

WARNING LIGHTS AND CHIMES
Shown in standard measure. Metric similar.
Warning lights and gauges can alert you to a vehicle condition that may
become serious enough to cause extensive repairs. A warning light may
illuminate when a problem exists with one of your vehicle’s functions.
Many lights will illuminate when you start your vehicle to make sure the
bulbs work. If any light remains on after starting the vehicle, refer to the
respective system warning light for additional information.
Service engine soon:The service
engine soon indicator light
illuminates when the ignition is first
turned to the on position to check
the bulb and to indicate whether the vehicle is ready for
inspection/maintenance (I/M) testing. Normally, the service engine soon
light will stay on until the engine is cranked, then turn itself off if no
malfunctions are present. However, if after 15 seconds the service engine
soon light blinks eight times, it means that the vehicle is not ready for
I/M testing. See theReadiness for Inspection/Maintenance (I/M)
testingin theMaintenance and Specificationschapter.
Solid illumination after the engine is started indicates the on-board
diagnostics system (OBD-II) has detected a malfunction. Refer to
On-board diagnostics (OBD-II)in theMaintenance and Specifications
chapter. If the light is blinking, engine misfire is occurring which could
damage your catalytic converter. Drive in a moderate fashion (avoid

Safety belt:Reminds you to fasten
your safety belt. A Belt-Minder
chime will also sound to remind you
to fasten your safety belt. Refer to
theSeating and Safety Restraints
chapter to activate/deactivate the Belt-Minderchime feature.
Charging system:Illuminates when
the battery is not charging properly.
If it stays on while the engine is
running, there may be a malfunction
with the charging system. Contact your authorized dealer as soon as
possible. This indicates a problem with the electrical system or a related
component.
Engine oil pressure:Illuminates
when the oil pressure falls below the
normal range, refer toEngine oilin
theMaintenance and
Specificationschapter.
AdvanceTrac:Flashes
momentarily when the
AdvanceTrac/traction control is
active. If the light remains on, have
the system serviced immediately, refer to theDrivingchapter for more
information.
AdvanceTracoff:Illuminates solid
when the traction control has been
disabled by the driver. Flashes for
3 seconds and turns solid when
trailer sway is disabled by driver.
Refer to theDrivingchapter for more information.
Low tire pressure warning:
Illuminates when your tire pressure
is low. If the light remains on at
start up or while driving, the tire
pressure should be checked. Refer
toInflating your tiresin theTires, Wheels and Loadingchapter. When
the ignition is first turned to on, the light will illuminate for three
seconds to ensure the bulb is working. If the light does not turn on or
begins to flash, have the system inspected by your authorized dealer. For
more information on this system, refer toTire pressure monitoring
system (TPMS)in theTires, Wheels and Loadingchapter.

Fuel gauge:Indicates
approximately how much fuel is left
in the fuel tank (when the ignition
is in the on position). The fuel
gauge may vary slightly when the
vehicle is in motion or on a grade.
The arrow near the fuel pump icon
indicates which side of the vehicle
the fuel filler door is located.
Refer toFilling the tankin theMaintenance and Specifications
chapter for more information.
MESSAGE CENTER
Your vehicle’s message center is capable of monitoring many vehicle
systems and will alert you to potential vehicle problems and various
conditions with an informational message followed by a long indicator
chime.
The message center display is located in the instrument cluster.

cycle through the following features:
TRIP A/B
Registers the distance of individual journeys. Press and release INFO
button until the A or B trip appears in the display (this represents the
trip mode). Press and hold the RESET button for two seconds to reset.
Refer toUNITSlater in this section to switch the display from Metric to
English.
MYKEY MILES (km) (if programmed)

Remember to turn the ignition off when refueling to allow this feature to
correctly detect the added fuel.
LOW FUEL LEVEL will display when you have approximately 50 miles
(80 km), to empty. Press RESET to clear this warning message. It will
return at approximately 25 miles (40 km), 10 miles (16 km) and 0 miles
(0 km) miles to empty.
Distance to empty is calculated using a running average fuel economy,
which is based on your recent driving history of 500 miles (800 km).
This value is not the same as the average fuel economy display. The
running average fuel economy is re-initialized to a factory default value if
the battery is disconnected.
AVG MPG (L/100km)
Average fuel economy displays your average fuel economy in miles/gallon
or liters/100 km.
If you calculate your average fuel economy by dividing distance traveled
by gallons of fuel used (liters of fuel used by 100 kilometers traveled),
your figure may be different than displayed for the following reasons:
•Your vehicle was not perfectly level during fill-up
•Differences in the automatic shut-off points on the fuel pumps at
service stations
•Variations in top-off procedure from one fill-up to another
•Rounding of the displayed values to the nearest 0.1 gallon (liter)
1. Drive the vehicle at least 5 miles (8 km) with the speed control
system engaged to display a stabilized average.
2. Record the highway fuel economy for future reference.
It is important to press the RESET button (press and hold RESET for
two seconds in order to reset the function) after setting the speed
control to get accurate highway fuel economy readings.
For more information refer toEssentials of good fuel economyin the
Maintenance and Specificationschapter.
MPG (L/km)
This displays instantaneous fuel economy as a bar graph ranging from↓
poor economy to↑excellent economy.
Your vehicle must be moving to calculate instantaneous fuel economy.
When your vehicle is not moving, this function shows↓, one or no bars
illuminated. Instantaneous fuel economy cannot be reset.
