Charging system
Illuminates when the
battery is not charging
properly.
Air bag readiness
Illuminates to confirm
that the air bags (front
or side) are
operational. If the light fails to illuminate, continues
to flash or remains on, have the system serviced
immediately.
Anti-theft system
Illuminates when the
SecuriLock
Passive
Anti-theft System is
armed. If the light fails to illuminate, continues to
flash or remains on, have the system serviced.
Service engine soon
Illuminates briefly to
ensure the system is
functional. If it comes
on after the engine is
started, one of the engine’s emission control systems
may be malfunctioning. The light may illuminate
without a driveability concern being noted. The
vehicle will usually be drivable and will not require
towing.
Light turns on solid:
Temporary malfunctions may cause the light to
illuminate. Examples are:
1. The vehicle has run out of fuel.
2. Poor fuel quality or water in the fuel.
3. The fuel cap may not have been properly installed
and securely tightened.
These temporary malfunctions can be corrected by
filling the fuel tank with high quality fuel of the

recommended octane and/or properly installing and
securely tightening the fuel cap. After three driving
cycles without these or any other temporary
malfunctions present, the light should turn off. (A
driving cycle consists of a cold engine startup
followed by mixed city/highway driving.) No
additional vehicle service is required.
If the light remains on, have your vehicle serviced at
the first available opportunity.
Light is blinking:
Engine misfire is occurring which could damage your
catalytic converter. You should drive in a moderate
fashion (avoid heavy acceleration and deceleration)
and have your vehicle serviced at the first available
opportunity.
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 is not installed
correctly. Check the
fuel cap for proper
installation. When the fuel filler cap is properly
re-installed, the light(s) will turn off after a period of
normal driving. Continuing to operate the vehicle
with the check fuel cap light on, or a mis-installed
fuel cap can activate theService Engine
Soon/Check Enginewarning light.
It may take a long period of time for the
system to detect an improperly installed fuel
filler cap.
For more information, refer toFuel filler capin the
Maintenance and specificationschapter.

Low fuel
Illuminates when the
fuel level in the fuel
tank is at, or near,
empty (refer toFuel
gaugein this chapter for more information).
O/D off (if equipped)
Illuminates when the
overdrive function has
been turned OFF using
the transmission control switch (TCS) on the
gearshift. If the light does not come on or the light
flashes steadily, have your vehicle serviced as soon
as possible, damage to the transmission could occur.
Traction Controlactive
Illuminates when the
Traction Control

system is active. It will
be lit for a minimum of
four seconds or for the duration of the Traction
Control
event.
For more information, refer to theDrivingchapter.
Anti-lock brake system (ABS)
To confirm the
anti-lock brake system
(ABS) warning light is
functional it will
momentarily illuminate when the ignition is turned
to the ON position (alternatively for some vehicles
when the ignition is moved from the ON position to
the START position, the light will momentarily
illuminate just prior to reaching the START
position). If the light remains on, continues to flash
or fails to illuminate, have the ABS serviced
immediately. If the ABS light remains on, it means
the anti-lock brake system has malfunctioned and is
disabled, however, the normal brake system will still
function unless the brake warning light also remains

Brake system warning
To confirm the brake
system warning light is
functional, it will
momentarily illuminate
when the ignition is turned to the ON position
(alternatively for some vehicles when the ignition is
moved from the ON position to START position, the
light will momentarily illuminate prior to reaching
the START position). It also illuminates if the
parking brake is engaged. If the brake system
warning light does not illuminate as described, seek
service immediately. Illumination after the parking
brake is released indicates low brake fluid level or a
brake system malfunction and the brake system
should be serviced immediately by a qualified
technician. Refer toBrakesin theDrivingchapter
for more information.

Indicates the
temperature of the
engine coolant. At
normal operating
temperature, the needle remains within the normal
area (the area between the“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 immediately and let the engine cool. Refer to

Never remove the coolant reservoir cap
while the engine is running or hot. Steam
and scalding liquid from a hot cooling system can
burn you badly.
This gauge indicates the temperature of the engine
coolant, not the coolant level. If the coolant is not at
its proper level the gauge indication will not be
accurate.
Engine oil pressure gauge
Indicates engine oil
pressure. At normal
operating temperature,
the needle will be in
the normal range (the area between the“L”and
“H”); if the needle goes below the normal range,
stop the vehicle as soon as safely possible and
switch off the engine immediately. Check the oil
level. Add oil if needed (refer toEngine oilin the
Maintenance and specificationschapter). If the oil
level is correct, have your vehicle checked at your
dealership or by a qualified technician.
Battery voltage gauge
Indicates battery
voltage. If the pointer
moves and stays
outside the normal
operating range, have the vehicle’s electrical system
checked as soon as possible.
Fuel gauge
Displays approximately
how much fuel is in the
fuel tank. The fuel
gauge may vary slightly
when the vehicle is in motion or on a grade.
