Air pressure gauge and warning buzzer (if equipped)
Indicates the amount of air pressure
in the brake system (green=primary,
red=secondary) in pounds per
square inch. When the pressure is
too low for normal brake operation
(less than 414 kPa [60 psi]) and the
ignition is turned to ON:
• a warning buzzer sounds
• the warning light illuminates
All vehicles have a dual-pointer air
pressure gauge to indicate the pressure in both brake circuits.
Vehicles equipped with rear air suspension also have a dual-pointer air
pressure gauge.
Do not drive the vehicle when the low air pressure buzzer is
sounding or the warning light is lit. These warnings indicate
there is not enough air pressure for the brake or suspension system to
operate properly.
Battery voltage gauge
Indicates battery voltage. If the
pointer moves and stays outside the
normal operating range, have the
vehicle’s electrical system checked
as soon as possible.
