If you drive up or down a steep hill, your vehicle speed may vary
momentarily slower or faster than the set speed; this is normal.
Speed control cannot reduce the vehicle speed if it increases above the
set speed on a downhill. If your vehicle speed is faster than the set
speed while driving on a downhill, you may want to shift to the next
lower gear or apply the brakes to reduce your vehicle speed.
If the vehicle speed falls below 48 km/h (30 mph) or engine RPM falls
below 1,000 RPM, your speed control will disengage; this is normal.
Pressing RESUME - (instrument panel-mounted controls) or RES
(steering wheel-mounted controls) will re-engage it.
Do not use the speed control in heavy traffic or on roads that
are winding, slippery, or unpaved.
To set a higher set speed
Instrument panel-mounted
controls:Press and hold SET +. If
the vehicle is moving, this will
increase vehicle speed; if the vehicle
is stationary, this will increase
engine RPM. Release the control
when the desired vehicle
speed/engine RPM is reached.
Press and release SET + to operate the tap-up function. Each press will
increase the set speed by 1.6 km/h (1 mph) or engine RPM in idle mode.
Steering wheel-mounted
controls:Press and hold SET
ACCEL. Release SET ACCEL when
the desired vehicle speed is
reached. SET ACCEL can also be
pressed and released to operate the
tap-up function which will increase
vehicle speed in increments of 1.6
km/h (1 mph).
You can accelerate with the accelerator pedal at any time during speed
control usage. Releasing the accelerator pedal will return your vehicle to
the previously programmed speed.

4. Turn the release stud one-quarter
turn to engage the stud tangs with
the slot in the pressure plate. Keep
the stud engaged and install the nut
on the release stud.
5. Tighten the nut until the spring is
fully caged and the brakes are
released. Do not loosen or remove
the release stud and nut unless the brake chamber is completely
assembled and is securely clamped.
6. When the air pressure is restored, unscrew and remove the release
stud and install in the carrying pocket. Install the access plug.
Exhaust brake (if equipped)
An exhaust brake is an optional
auxiliary braking system that assists,
but does not replace, the primary
service brake system. An on-off
switch on the instrument panel, in
combination with the accelerator
and clutch pedal switches, allows
the operator to make maximum use
of the exhaust brake in the
following conditions:
•off-highway driving
•mountain driving
•heavy traffic
•high speed highway driving

Trailer brake hand control (if equipped)
The hand control, located on the
right-hand side of the instrument
panel, is used to apply the trailer
service brakes which are
independent of the truck or tractor
service brakes.
The hand control should
never be used to apply the
brakes when the tractor and
trailer are parked unattended. Air
may leak from the system and the
vehicle could possibly move,
resulting in possible property
damage, personal injury or death.
The hand control operates a valve that provides gradual control of air
pressure applied; when the valve is only partially applied, the trailer
brakes can be overridden by pressing fully on the brake pedal.
To apply the trailer brakes using the hand control, move the lever
downward. The further the lever is pushed downward, the greater the air
pressure is applied to the brakes. The lever will remain in place until
manually moved.
To release the trailer brakes, move the lever upward completely.
Trailer air supply and parking brake modular controls (if equipped)
The trailer air supply valve delivers air to the trailer supply and will
automatically pop out, shutting off the trailer supply if pressure is
decreased to approximately 249 kPa (35 psi).

When the Traction Controlswitch, located on the instrument panel, is
in the off position, the traction control light will be illuminated.
If you should become stuck in snow or ice or on a very slippery road
surface, try switching the Traction Controlsystem off. This may allow
excess wheel spin to“dig”the vehicle out and enable a successful
“rocking”maneuver.
Aggressive driving in any road conditions can cause you to lose
control of your vehicle increasing the risk of severe personal
injury or property damage. The occurrence of a Traction Control
event is an indication that at least some of the tires have exceeded
their ability to grip the road; this may lead to an increased risk of loss
of vehicle control, vehicle rollover, personal injury and death. If you
experience a severe road event, SLOW DOWN.
AIR SUSPENSION (IF EQUIPPED)
Note:The vehicle must not be operated without air in the suspension
springs. Operating the vehicle without air in the air suspension springs
will damage the suspension, degrade ride performance and may cause
property damage.
The suspension system automatically adjusts to different loads to
maintain a constant frame height. The system allows for ease of vehicle
loading and provides improved vehicle ride and increased driver comfort.
Air suspension dump switch (if equipped)
The system is controlled by a switch
located on the instrument panel.
The switch will operate only when
the ignition is in the ACC
(Accessory) or IGNITION positions
and the air tanks have sufficient
pressure to fill the air springs. When
the ignition is turned off, the
suspension will remain in whatever
state it was last set.
Note:The suspension will dump air when the ignition is in the ACC or
IGNITION position, but will only fill when the ignition is in the IGNITION
position.
When the upper portion of the switch is pressed and the vehicle speed is
below 8 kn/h (5 mph), air supplied to the air spring is exhausted,
