CONTROLS AND DISPLAY
OPTIONAL GAUGES
WARNING! The air pressure warning light and
the audible alarm indicate a dangerous situation.
There is not enough air pressure in the
reservoirs for repeated braking and the brake
system has failed. If air pressure falls below
60 psi (414 kPa) the spring brakes could suddenly
apply, causing a wheel lockup, loss of
control, or your vehicle to be overtaken by following
vehicles. You could be in an accident
involving death or personal injury. If these
alarms come on while you are driving, immediately
bring your vehicle to a safe stop off of
the road. If the light and alarm do not turn off
at start-up, do not try to drive the vehicle until
the problem is found and fixed.
Optional Gauges
Maximum transmission temperature may vary, depending
upon the transmission and type of lubricant. Check your
transmission’s owner’s manual.
