Instrument Cluster
Brake system warning light: To
confirm the brake system warning
light is functional, this light will
momentarily illuminate when the
ignition is turned to the ON position when the engine is not running. If
the brake system warning light does not illuminate at this time, seek
service immediately from your dealership. Illumination after starting the
vehicle indicates a brake system fault and should be inspected
immediately by your dealership.
Note: The Brake System Warning light may be accompanied by a
warning buzzer or chime.
If equipped with an air brake system, the warning light stays on until
the air pressure builds up to 60 psi (414 kPa). If the air pressure drops
below 60 psi (414 kPa) during operation, the remaining brake system is
still operational but the stopping distance will be greater.
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 dealer immediately. Driving
extended distances with the parking brake engaged can cause brake
failure and the risk of personal injury.
Wait to start: Indicates the air
intake heater is in operation and
special starting procedures are
required. Refer to Starting in the
Driving chapter.
WARNING: If equipped with an air intake heater, DO NOT use
ether or any other starting fluids. The use of starting fluids
(ether) in an engine equipped with an air intake heater could result in
damage and/or personal injury.
