SAFETY AND ENVIRONMENT PROTECTION
Warning symbols in this guide
How can you reduce the risk of personal injury to yourself or others? In
this guide, answers to such questions are contained in comments
highlighted by the warning triangle symbol. These comments should be
read and observed.
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.
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.
Do not add friction modifier compounds or special break-in oils during
the first few thousand miles (kilometers) of operation, since these
additives may prevent piston ring seating. See Engine oil in the
Maintenance and Specifications chapter for more information on oil
usage.

WARNING LIGHTS AND CHIMES
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.
Check engine: The Check Engine
indicator light illuminates when the
ignition is first turned to the ON
position to check the bulb. 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 the Maintenance and Specifications
chapter. If the light is blinking, engine misfire is occurring which could
damage your catalytic converter. Drive in a moderate fashion (avoid
heavy acceleration and deceleration) and have your vehicle serviced
immediately by your authorized dealer.
Under engine misfire conditions, excessive exhaust temperatures
could damage the catalytic converter, the fuel system, interior
floor coverings or other vehicle components, possibly causing a fire.

Check fuel cap: Illuminates when
the fuel cap may not be properly
installed. Continued driving with
this light on may cause the Check
engine warning light to come on,
refer to Fuel filler cap in the
Maintenance and Specification chapter.
Brake system warning light: To
confirm the brake system warning
light is functional, it will
momentarily illuminate when the
ignition is turned to the ON position
when the engine is not running, or in a position between ON and START,
or by applying the parking brake when the ignition is turned to the ON
position. If the brake system warning light does not illuminate at this
time, seek service immediately from your authorized dealer. Illumination
after releasing the parking brake indicates low brake fluid level or a
brake system malfunction and the brake system should be inspected
immediately by your authorized dealer.
Driving a vehicle with the brake system warning light on is
dangerous. A significant decrease in braking performance may
occur. It will take you longer to stop the vehicle. Have the vehicle
checked by your authorized dealer.
Anti-lock brake system: If the
ABS light stays illuminated or
continues to flash, a malfunction has
been detected, have the system
serviced immediately by your
authorized dealer. Normal braking is still functional unless the brake
warning light also is illuminated.
Airbag readiness: If this light fails
to illuminate when ignition is turned
to ON, continues to flash or remains
on, have the system serviced
immediately by your authorized dealer. A chime will also sound when a
malfunction in the supplemental restraint system has been detected. P!

the battery is not charging properly.
Engine oil pressure: Illuminates
when the oil pressure falls below the
normal range, refer to Engine oil in
the Maintenance and
Specifications chapter.
Traction Control  : Illuminates
when the Traction Control  is
active. If the light remains on, have
the system serviced immediately,
refer to the Driving chapter for
more information.

Engine coolant temperature
gauge: Indicates engine coolant
temperature. At normal operating
temperature, the needle will be in
the normal range (between “H” and
“C”). If it enters the red section,
the engine is overheating. Stop
the vehicle as soon as safely
possible, switch off the engine and let the engine cool.
Never remove the coolant reservoir cap while the engine is
running or hot.
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 FUEL icon and arrow indicates
which side of the vehicle the fuel
filler door is located.
Refer to Filling the tank in the Maintenance and Specifications
chapter for more information.
Tachometer: Indicates the engine
speed in revolutions per minute.
Driving with your tachometer
pointer continuously at the top of
the scale may damage the engine.

Distance to empty (DTE)
Selecting this function from the
INFO menu estimates approximately
how far you can drive with the fuel
remaining in your tank under
normal driving conditions.
Remember to turn the ignition OFF
when refueling to allow this feature to correctly detect the added fuel.
The DTE function will display LOW FUEL LEVEL when you have
approximately 50 miles (80 km) to empty. If you RESET this warning
message, this display will return within 10 minutes.
DTE 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
reinitialized to a factory default value if the battery is disconnected.
Average fuel economy (AFE)
Select this function from the INFO
menu to display your average fuel
economy in miles/gallon or liters/100
km.
If you calculate your average fuel
economy by dividing gallons of fuel
used by gallons of fuel used by 100 miles traveled (kilometers traveled
by liters used), 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 control (press and hold RESET for 2
Seconds in order to reset the function) after setting the speed control to
get accurate highway fuel economy readings.
For more information refer to Fuel Information in the Maintenance
and Specifications chapter.

Front safety belt pretensioners
The safety belt pretensioners at the front outboard seating positions are
designed to tighten the safety belts firmly against the occupant’s body
during frontal collisions, and in side collisions and rollovers when the
vehicle is equipped with the side air curtain system. This helps increase
the effectiveness of the safety belts. In frontal collisions, the safety belt
pretensioners can be activated alone or, if the collision is of sufficient
severity, together with the front airbags.
Front safety belt energy management retractors
The front outboard safety belt energy management retractors allow
webbing to be pulled out of the retractor in a gradual and controlled
manner in response to the occupant’s forward momentum. This helps
reduce the risk of force-related injuries to the occupant’s chest by
limiting the load on the occupant. Refer to Energy management feature
section in this chapter.
Determining if the Personal Safety System  is operational
The Personal Safety System  uses a warning light in the instrument
cluster or a back-up tone to indicate the condition of the system. Refer
to the Warning light section in the Instrument Cluster chapter.
Routine maintenance of the Personal Safety System  is not required.
The Restraints Control Module (RCM) monitors its own internal circuits
and the circuits for the airbag supplemental restraints, crash sensor(s),
safety belt pretensioners, front safety belt buckle sensors, driver seat
position sensor, and front passenger sensing system. In addition, the
RCM also monitors the restraints warning light in the instrument cluster.
A difficulty with the system is indicated by one or more of the following.
• The warning light will either flash or stay lit.
• The warning light will not illuminate immediately after ignition is
turned on.
• A series of five beeps will be heard. The tone pattern will repeat
periodically until the problem and warning light are repaired.
If any of these things happen, even intermittently, have the Personal
Safety System  serviced at an authorized dealer immediately. Unless
serviced, the system may not function properly in the event of a
collision.
