Windshield wiper/washer controls
Rotate the windshield wiper control
to the desired interval, low or high
speed position.
The bars of varying length are for
intermittent wipers. When in this
position rotate the control upward
for fast intervals and downward for
slow intervals.
Push the control on the end of the
stalk to activate washer. Push and
hold for a longer wash cycle. The
washer will automatically shut off
after ten seconds of continuous use.
TILT STEERING
Pull the tilt steering control toward
you to move the steering wheel up
or down. Hold the control while
adjusting the wheel to the desired
position, then release the control to
lock the steering wheel in position.

Lap belts
The front center and rear center lap belts do not adjust automatically.
The lap belt should fit snugly and as low as possible around the
hips, not across the waist.
Insert the tongue into the correct
buckle (the buckle closest to the
direction the tongue is coming
from). To lengthen the belt, turn the
tongue at a right angle to the belt
and pull across your lap until it
reaches the buckle. To tighten the
belt, pull the loose end of the belt
through the tongue until it fits snugly across the hips.
Shorten and fasten the belt when
not in use.
Vehicle sensitive mode
The vehicle sensitive retractor allows free shoulder belt length
adjustment to your movements and locks in response to vehicle
movement. For example, if the driver brakes suddenly or turns a corner
sharply, or the vehicle receives an impact of approximately 5 mph (8
km/h) or more, the combination safety belts will lock to help reduce
forward movement of the driver and passengers.
Front safety belt height adjustment
SuperCab and Crew Cab vehicles have safety belt height adjustments for
the driver and front passenger. Adjust the height of the shoulder belt so
the belt rests across the middle of your shoulder.

Do not manually adjust the automatic slack adjusters to correct
excessive pushrod stroke as it may result in reduced brake
effectiveness and a vehicle crash. Excessive pushrod stroke indicates
that a problem exists with the automatic adjuster, with the installation
of the adjuster, or with foundation brake components that manual
adjustment will not remedy. Seek service from a qualified facility for
excessive pushrod stroke.
Inspect the brake lining every maintenance interval. When brake lining or
blocks are worn to within 1/16 inch (1.6 mm) of rivets, brake lining must
be replaced. This inspection or adjustment should only be performed by
a qualified technician and must be in accordance with instructions
provided by the service manual.
Do not back off or disconnect the front brakes so that they are less
effective, letting the rear brakes do all the stopping of the vehicle. Do
not overlook the brakes on the trailer, either. Brake condition on the
trailer is just as important as the tractor. Proper brake balance on trucks
and tractor-trailers is essential for effective braking.
Once a year, the entire brake system must be inspected. Check the
following:
• Any rubber as it may deteriorate whenever used. Rubber brake
components should be inspected by a qualified technician and
replaced as necessary. Replacement intervals vary according to the
severity and length of vehicle service.
• Condition of brake drums, brake chambers and slack adjusters.
• System for air leaks.
• Hose or pipes for rust, damage and deterioration.
• Operation of service and parking brakes.
Some parts such as air brake chamber diaphragm, air compressor and air
cleaner should be inspected periodically and replaced if considered
unserviceable.
Air brakes - air dryer
Performance of desiccant or after-cooler type air dryers is dependent on
climatic conditions in which your vehicle is operating. Maintenance
schedules must be established for each specific operation.
The use of an air dryer on a vehicle does not eliminate the need to
periodically drain the air reservoirs.
