Temperature Gauge
(Uplevel)
Sport Mode Shown, Track Mode Similar
This gauge shows the engine coolant
temperature.
If the gauge pointer moves into the
red zone, the engine is too hot.
This reading indicates the same thing
as the warning light. It means that the
engine coolant has overheated. If the
vehicle has been operating under
normal driving conditions, pull off the
road, stop the vehicle, and turn off the
engine as soon as possible. See Engine
Overheating 0342 for more
information.
Seat Belt Reminders
Driver Seat Belt Reminder Light
There is a driver seat belt reminder
light on the instrument cluster.
When the vehicle is started, this light
flashes and a chime may come on to
remind the driver to fasten their
seat belt.
Then the light stays on solid until the
belt is buckled. This cycle may
continue several times if the driver
remains or becomes unbuckled while
the vehicle is moving.
If the driver seat belt is buckled,
neither the light nor the chime
comes on.

When the vehicle is started, the
passenger airbag status indicator will
light ON and OFF, and the symbols for
on and off, for several seconds as a
system check. Then, after several more
seconds, the status indicator will light
either ON or OFF, and either the
symbol for on or off, to let you know
the status of the front outboard
passenger frontal airbag and knee
airbag.
If the word ON, and the on symbol, is
lit on the passenger airbag status
indicator, it means that the front
outboard passenger frontal airbag and
knee airbag are allowed to inflate.
If the word OFF, and the off symbol, is
lit on the passenger airbag status
indicator, it means that the passenger
sensing system has turned off the
front outboard passenger frontal
airbag and knee airbag.If, after several seconds, all of the
symbols remain lit, or if no symbols
are lit, or if the airbag readiness light
is on, there may be a problem with
the lights or the passenger sensing
system. See your dealer for service
right away.
{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
098 for more
information, including important
safety information.
Charging System Light
The charging system light comes on
briefly when the ignition is turned on,
but the engine is not running, as a
check to show the light is working.
It should go out when the engine is
started.
If the light stays on, or comes on
while driving, there may be a problem
with the electrical charging system.
Have it checked by your dealer.
Driving while this light is on could
drain the battery.
When this light comes on, or is
flashing, the Driver Information
Center (DIC) also displays a message.
If a short distance must be driven
with the light on, be sure to turn off
all accessories, such as the radio and
air conditioner. Find a safe place to
stop the vehicle.

full tank of the proper fuel to turn
the light off. SeeRecommended Fuel
(LSY 2.0L L4 Turbo Engine) 0311 or
Recommended Fuel (L3B 2.7L L4
Turbo and LF4 3.6L V6 Twin Turbo
Engines) 0311.
If the light remains on, see your
dealer.
Emissions Inspection and
Maintenance Programs
If the vehicle requires an Emissions
Inspection/Maintenance test, the test
equipment will likely connect to the
vehicle's Data Link Connector (DLC).
The DLC is under the instrument
panel to the left of the steering wheel.
Connecting devices that are not used
to perform an Emissions Inspection/
Maintenance test or to service the vehicle may affect vehicle operation.
See
Add-On Electrical Equipment 0321.
See your dealer if assistance is needed.
The vehicle may not pass
inspection if:
.The light is on when the engine is
running.
.The light does not come on when
the ignition is in Service Mode.
.Critical emission control systems
have not been completely
diagnosed. If this happens, the
vehicle would not be ready for
inspection and might require
several days of routine driving
before the system is ready for
inspection. This can happen if the
12-volt battery has recently been
replaced or run down, or if the
vehicle has been recently serviced.
See your dealer if the vehicle will not
pass or cannot be made ready for
the test.
Brake System Warning
Light
MetricEnglish
This light should come on briefly
when the vehicle is turned on. If it
does not come on then, have it fixed
so it will be ready to warn you if there
is a problem.
If the light comes on and stays on at
start up, there is a brake problem.
Have the brake system inspected
right away.
If the light comes on while driving,
pull off the road and stop carefully.
The brake system has electric brake
boost. Vehicle speed may be limited
when the brake system warning light

tire pressures and the TPMS.
When the Light Is On Steady
This indicates that one or more of the
tires are significantly underinflated.
A Driver Information Center (DIC) tire

Stop as soon as possible, and inflate
the tires to the pressure value shown
on the Tire and Loading Information
label. SeeTire Pressure 0370.
When the Light Flashes First and
Then Is On Steady
If the light flashes for about a minute
and then stays on, there may be a
problem with the TPMS. If the problem is not corrected, the light will
come on at every ignition cycle. See

0373.
Engine Oil Pressure Light
Caution
Lack of proper engine oil
maintenance can damage the
engine. Driving with the engine oil
low can also damage the engine.
The repairs would not be covered
by the vehicle warranty. Check the
oil level as soon as possible. Add oil
if required, but if the oil level is
within the operating range and the
oil pressure is still low, have the
vehicle serviced. Always follow the
maintenance schedule for changing
engine oil.
