AIR SUSPENSION DUMP VALVE
The dump valve switch activates the
dump valve. The dump valve
releases air from the air springs and
lowers the rear suspension, allowing
you to back under a low trailer
when necessary.
DRIVING WITH A MANUAL TRANSMISSION, IF EQUIPPED
Continued use of a damaged or worn clutch, prolonged clutch
slippage or downshifting at excessive speeds can result in a
failure of the engine, transmission or clutch components.
To avoid premature clutch wear and failure, do not drive with
your foot resting on the clutch pedal or use it to hold the vehicle
at a standstill on an upgrade as when waiting for a traffic light.
Manual transmission shift patterns
are displayed on the shift lever
knob.
Study this information carefully before you drive the vehicle even though
you may be familiar with similar units. Do not attempt to drive the
vehicle without knowing the exact shift pattern of the transmission.
Consult your authorized dealer if any questions exist as to the shifting
instructions posted in your vehicle.
