Warning Lights, Gauges, and
Indicators
Warning lights and gauges can signal that something is
wrong before it becomes serious enough to cause an
expensive repair or replacement. Paying attention to the
warning lights and gauges could prevent injury.
Warning lights come on when there might be or there is
a problem with one of the vehicle's functions. Some
warning lights come on briefly when the engine is
started to indicate they are working.
Gauges can indicate when there might be or there is
a problem with one of the vehicle's functions. Often
gauges and warning lights work together to indicate a
problem with the vehicle.
When one of the warning lights comes on and stays on
while driving, or when one of the gauges shows there
could be a problem, check the section that explains
what to do. Follow this manual's advice. Waiting to do
repairs can be costly and even dangerous.

Safety Belt Reminders
Driver Safety Belt Reminder Light
When the engine is started, a chime sounds for several
seconds to remind a driver to fasten the safety belt,
unless the driver safety belt is already buckled.
The safety belt light
comes on and stays on
for several seconds, then
flashes for several more.
This chime and light are repeated if the driver remains
unbuckled and the vehicle is in motion. If the driver
safety belt is already buckled, neither the chime nor the
light comes on.
Passenger Safety Belt Reminder Light
For vehicles equipped with the passenger safety belt
reminder light, several seconds after the engine is
started, a chime sounds for several seconds to remind
the front passenger to buckle their safety belt. The
passenger safety belt light, located on the instrument
panel, comes on and stays on for several seconds and
then flashes for several more.
This chime and light are
repeated if the passenger
remains unbuckled and
the vehicle is in motion.
If the passenger safety belt is buckled, neither the
chime nor the light comes on.
The front passenger safety belt warning light and chime
may turn on if an object is put on the seat such as a
briefcase, handbag, grocery bag, laptop or other
electronic device. To turn off the warning light and or
chime, remove the object from the seat or buckle the
safety belt.

Airbag Readiness Light
The system checks the airbag's electrical system for
possible malfunctions. If the light stays on it indicates
there is an electrical problem. The system check
includes the airbag sensor, the pretensioners, the
airbag modules, the wiring and the crash sensing and
diagnostic module. For more information on the airbag
system, seeAirbag System on page 2‑60.
The airbag readiness
light flashes for a few
seconds when the engine
is started. If the light does
not come on then, have it
fixed immediately.
{WARNING:
If the airbag readiness light stays on after the
vehicle is started or comes on while driving, it
means the airbag system might not be working
properly. The airbags in the vehicle might not
inflate in a crash, or they could even inflate
without a crash. To help avoid injury, have the
vehicle serviced right away.
If there is a problem with the airbag system, an airbag
Driver Information Center (DIC) message can also
come on. See DIC Warnings and Messages
on
page 4‑48for more information.

Passenger Airbag Status Indicator
If the vehicle has one of the passenger airbag status
indicators pictured in the following illustrations, then the
vehicle has a passenger sensing system for the right
front passenger position. The passenger airbag status
indicator, if equipped, is on the instrument panel. See
Passenger Sensing System
on page 2‑70for important
safety information.
In addition, if the vehicle has a passenger sensing
system for the right front passenger position, the label
on the vehicle's sun visors refer to “ADVANCED
AIRBAGS”.
United StatesCanada
When the vehicle is started, the passenger airbag
status indicator will light ON and OFF, or the symbol for
on and off, for several seconds as a system check.
If using remote start, if equipped, to start the vehicle
from a distance, you may not see the system check. Then, after several more seconds, the status indicator
will light either ON or OFF, or either the on or off symbol
to let you know the status of the right front passenger
frontal airbag.
If the word ON or the on symbol is lit on the passenger
airbag status indicator, it means that the right front
passenger frontal airbag is enabled (may inflate).
If the word OFF or the off symbol is lit on the airbag
status indicator, it means that the passenger sensing
system has turned off the right front passenger frontal
airbag.
If, after several seconds, both status indicator lights
remain on, or if there are no lights at all, there may be a
problem with the lights or the passenger sensing
system. See your dealer/retailer for service.
{WARNING:
If the airbag readiness light ever comes on and
stays on, it means that something may be wrong
with the airbag system. To help avoid injury to
yourself or others, have the vehicle serviced right
away. See
Airbag Readiness Light
on page 4‑27
for more information, including important safety
information.

Brake System Warning Light
The vehicle's hydraulic brake system is divided into two
parts. If one part is not working, the other part can still
work and stop the vehicle. For good braking both parts
need to be working well.
If the warning light comes on, there is a brake problem.
Have the brake system inspected right away.
United StatesCanada
This light should come on briefly when the engine is
started. If it does not come on then, have it fixed so it
will be ready to warn if there is a problem. When the ignition is on, the brake system warning light
also comes on when the parking brake is set. The light
stays on if the parking brake does not fully release. If it
stays on after the parking brake is fully released, it
means the vehicle has a brake problem.
If the light comes on while driving, pull off the road and
stop carefully. Make sure the parking brake is fully
released. The pedal might be harder to push or, the
pedal could go closer to the floor. It can take longer to
stop. Try turning off and restarting the vehicle one or
two times, if the light is still on, have the vehicle towed
for service. See
Towing Your Vehicle on page 5‑29.
{WARNING:
The brake system might not be working properly if
the brake system warning light is on. Driving with
the brake system warning light on can lead to a
crash. If the light is still on after the vehicle has
been pulled off the road and carefully stopped,
have the vehicle towed for service.

Antilock Brake System (ABS)
Warning Light
For vehicles with the
Antilock Brake System
(ABS), this light comes
on briefly when the
engine is started.
If it does not, have the vehicle serviced by your
dealer/retailer. If the system is working normally the
indicator light then goes off. If the ABS light stays on, turn the ignition off. If the light
comes on while driving, stop as soon as it is safely
possible and turn the ignition off. Then start the engine
again to reset the system. If the ABS light stays on,
or comes on again while driving, the vehicle needs
service. If the regular brake system warning light is not
on, the vehicle still has brakes, but not antilock brakes.
If the regular brake system warning light is also on, the
vehicle does not have antilock brakes and there is a
problem with the regular brakes. See
Brake System
Warning Light on page 4‑30.

Enhanced Traction System (ETS)
Indicator/Warning Light
For vehicles with the
Enhanced Traction
System (ETS), this light
serves as an indicator
and warning light.
This light comes on briefly while the engine is started.
If it does not, have the vehicle serviced by your dealer/
retailer. If the system is working normally the indicator
light then goes off. If the indicator/warning light is on and not flashing, the
ETS system could have been disabled. Check all
related Driver Information Center (DIC) messages to
determine whether the system has been turned off or if
the system is not working properly and the vehicle
requires service. If the ETS has been disabled, wheel
spin is not limited.
If the indicator/warning light is on and flashing, the ETS
is actively working. The LOW TRACTION DIC message
also appears when the system is actively limiting
wheel spin.

System (TCS)
indicator/warning light
comes on briefly when
the engine is started.
If it does not, have the vehicle serviced by the dealer/
retailer. If the system is working normally the indicator
light goes off.
This light, along with the appropriate Driver Information
Center (DIC) messages, indicates when the ESC
system and the TCS are working or are disabled. If the light comes on and stays on, the TCS and
potentially the ESC system have been disabled.
Check the DIC messaging to determine which system
is turned off, or not working. If the system is not
working, the vehicle needs service. See your
dealer/retailer.
When the TCS is disabled, wheel spin is not limited.
When the ESC system is disabled, the system does
not aid in maintaining vehicle directional control.
If the light comes on and flashes, the TCS or the ESC
system is actively working. When the LOW TRACTION
message appears, the system is limiting wheel spin.
When the ESC ACTIVE message appears, the system
is aiding in maintaining vehicle directional control.
