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 contact your authorized dealer
as soon as possible.
If the light remains on while driving, the temperature of the engine may
be too high; refer to Engine coolant in the Maintenance and
Specifications chapter.
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.
Powertrain malfunction
indicator: Illuminates when a
powertrain or an AWD fault has
been detected. Contact your
authorized dealer as soon as
possible.
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, contact your authorized dealer as soon as possible. Illumination
after releasing the parking brake indicates low brake fluid level. Contact
your authorized dealer as soon as possible.
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.
Contact 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.
