Warning (Continued)
may be overheating, continued operation
of the engine, even for a short time, may
result in a fire and the risk of personal
injury and severe vehicle damage. Take
immediate action as outlined in Engine
Overheating. See
Caution
If the needle goes up above the upper
limit and enters the H zone, the engine is
likely to overheat. Immediately pull
safely off the road out of the way of
traffic and take the necessary actions to
deal with engine overheating. If the
needle nears the H zone but does not
cross into it, this is not a problem, but
check the engine coolant level in the
reservoir. Add engine coolant as
necessary.

Brake Air Pressure Gauge
This gauge indicates the pressure of the
compressed air in the air tank. If the needle
enters the red zone, the brake air pressure
warning light comes on and the warning
buzzer sounds. To stop the buzzer, pull up
the parking brake lever when the vehicle has
come to a complete stop in a safe area.
If the brake air pressure warning light comes
on, immediately look for a safe place to pull
off the road and stop. Engage the parking
brake after stopping.
Place the selector lever in the N position and
firmly press the brake pedal. Then, run the
engine at idle to increase air pressure.
If air pressure will not increase, or there is a
great difference between the readings of the
two gauges, or it takes time for the needles
to go up, see your dealer.

Warning
Do not place the vehicle in D (Drive) or
attempt to drive the vehicle if the brake
air pressure gauge needles are in the red
zone or the brake air pressure warning
light is on. The brakes are not fully
functional and it is dangerous to operate
the vehicle. Set the parking brake by
moving the lever to the up position, and
do not disengage the parking brake or
shift the vehicle to D (Drive) until air
pressure levels have returned to normal.
