WARNING LIGHTS AND CHIMES
Air clean warning (if equipped)
Illuminates when the ignition is
turned to the ON position and the
engine is off. The light also
illuminates when the air system is
restricted (dirty, clogged).
Brake reserve system warning (if equipped)
Illuminates to indicate normal
Hydromax booster reserve system
activation when the engine is OFF
and the service brake pedal is
applied, or when the ignition is in
the ON or START position.
This light may also illuminate momentarily if the engine is running and
the driver turns the steering wheel fully in one direction while braking.
If the light remains on while the engine is running, this indicates
inadequate hydraulic booster pressure or reserve pump system failure.
Stop the vehicle safely as soon as possible and seek service immediately.

Charging system
Illuminates when the ignition is
turned to the ON position and the
engine is off. The light also
illuminates when there is no
alternator output, or an over voltage
condition requiring electrical system service.
Brake system warning
Momentarily illuminates when the
ignition is turned to the ON position
and the engine is off. If the brake
warning lamp does not illuminate at
this time seek service immediately.
If equipped with a hydraulic brake system and the warning lamp remains
illuminated after engine start up, this indicates a brake system
malfunction. Stop the vehicle safely as soon as possible and seek service
immediately.
If equipped with an air brake system, the warning light stays on until the
air pressure builds up to 414 kPa (60 psi). If the air pressure drops
below 414 kPa (60 psi) during operation, the remaining brake system is
still operational but the stopping distance will be greater.
Parking brake warning (Hydraulic brakes only)
Momentarily illuminates when the
ignition is turned to the ON position
and the engine is off. Also
illuminates when the parking brake
is engaged. If the brake warning
lamp does not illuminate at these
times, seek service immediately.

High beams
Illuminates when the high beam
headlamps are turned on.
Anti-lock brake system (ABS)
Momentarily illuminates when the
ignition is turned to the ON position
and the engine is off. If the light
remains on after the vehicle is
started, continues to flash or fails to
illuminate, have the system serviced immediately. With the ABS light on,
the anti-lock brake system is disabled and normal braking is still effective
unless the brake warning light also remains illuminated.
Wait to start
Indicates the air intake heater is in
operation and special starting
procedures are required. Refer to
theStartingchapter.
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.

GAUGES
Fuel gauge
Displays approximately how much
fuel is in the fuel tank (when the
key is in the ON position). The fuel
gauge may vary slightly when the
vehicle is in motion or after
refueling. The ignition should be in
the OFF position while the vehicle is
being refueled. When the gauge first
indicates empty, there is a small
amount of reserve fuel in the tank.
When refueling the vehicle from an empty indication, the amount of fuel
that can be added will be less than the advertised capacity due to the
reserve fuel.
Engine coolant temperature gauge
Indicates the temperature of the
engine coolant. At normal operating
temperature, the needle remains
within the normal area (the area
between the ªHº and ªCº). If it
enters the red section, the engine is
overheating. Stop the vehicle as
soon as safely possible, switch off
the engine immediately and let the
engine cool. Refer toEngine
coolantin theMaintenance and
carechapter.
