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 it illuminates when you are driving, check that the parking brake is not
engaged. If the parking brake is not engaged, this indicates low brake
fluid level or a brake system malfunction. Have the system checked
immediately by your authorized dealer.
WARNING: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 as soon as possible.
Driving extended distances with the parking brake engaged can cause
brake failure and the risk of personal injury.
Charging system (RTT)
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.
Door ajar (RTT)
Displays when the ignition is on and any door is not completely
closed.
Engine oil pressure (RTT)
Illuminates when the oil pressure falls below the normal range.
Engine coolant temperature (RTT)
Illuminates when the engine coolant temperature is high. Stop
the vehicle as soon as possible, switch off the engine and let
cool.

Low washer fluid (RTT)
Illuminates when the windshield washer fluid is low.
Parking Lamps (RTT)
It will illuminate when you switch the parking lamps on.
Powertrain malfunction/reduced power
Illuminates when a powertrain or an 4WD fault has been
detected. Contact your authorized dealer as soon as possible.
Safety belt
Reminds you to fasten your safety belt. A Belt-Minder® chime
will also sound to remind you to fasten your safety belt.
Service engine soon
Theservice engine soonindicator 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 the
Readiness for inspection/maintenance (I/M) testingin theFuel and
Refuelingchapter.
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 theFuel and Refuelingchapter. 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.
WARNING: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. Have an authorized dealer service your vehicle immediately.
