WARNING:Exercise great caution when working on vehicle
equipped with an automatic fan clutch. The fan starts in motion
only after the engine coolant reaches a predetermined temperature or
the refrigerant pressure (if equipped with air conditioning) reaches a
predetermined setting. The fan starts at this point with no advance
warning. Never reach near, or permit objects to protrude into, the fan
blade radius while the engine is running as this could result in vehicle
damage, personal injury or death.

Recirculated air engages automatically when MAX A/C is selected or can
be engaged manually in any airflow mode except
(defrost). When
the ignition switch is turned off and back on, the climate system returns
to the recirculated air mode only if the A/C button LED is illuminated
and the air distribution selection is either
(panel) or
(panel/floor).
6.MAX A/C (if equipped):Distributes recirculated air through the
instrument panel vents to cool the vehicle. This re-cooling of the interior
air is more economical and efficient than normal A/C mode. Recirculated
air may also help reduce undesirable odors from entering the vehicle.
Press the MAX A/C button again for normal A/C operation.
7.Temperature control:Controls the temperature of the airflow in the
vehicle.
8.
Fan speed adjustment:Controls the volume of air circulated in
the vehicle.
9.
Power:Press to activate/deactivate the climate control system.
When the system is off, outside air is prevented from entering the
vehicle.
Operating tips
•To reduce fog build-up on the windshield during humid weather,
select
(defrost) or(floor/defrost). Temperature and/or fan
speed can also be increased to improve clearing.
•To reduce humidity build-up inside the vehicle: do not drive with the
system off or with recirculated air engaged and A/C off.
•Do not put objects under the front seats that will interfere with the
airflow to the back seats.
•Remove any snow, ice or leaves from the air intake area at the base of
the windshield.
•To improve the A/C cool down, drive with the windows slightly open
for 2-3 minutes after start up or until the vehicle has been “aired out.”
•A small amount of air may be felt from the floor vent regardless of the
air distribution setting that is selected.
If you are driving during extreme high ambient temperatures and idling
for extended periods of time in gear, it is recommended to run the A/C
in the MAX A/C position, adjust the blower fan speed to the lowest
setting and put the vehicle’s transmission into the P (Park) position to
continue to receive cool air from your A/C system.

Reasons given... Consider...
“I have an air bag” Air bags offer greater protection when
used with safety belts. Frontal air
bags are not designed to inflate in
rear and side crashes or rollovers.
“I’d rather be thrown clear” Not a good idea.Peoplewho are
ejected are 40 times more likely
to DIE.Safety belts help prevent
ejection, WE CAN’T “PICK OUR
CRASH”.
WARNING:Do not sit on top of a buckled safety belt or insert a
latchplate into the buckle to avoid the Belt-Minderchime. To do
so may adversely affect the performance of the vehicle’s air bag system
One-time disable
Any time the safety belt is buckled and then unbuckled during an
ignition ON cycle, Belt-Minderis disabled for that ignition cycle only.
Deactivating/Activating the Belt-Minderfeature
Read Steps 1-9 thoroughly before proceeding with the
deactivation/activation programming procedure.
The Belt-Minderfeature can be deactivated/activated by performing the
following procedure:
Before following the procedure, make sure that:
•The parking brake is set.
•The gearshift is in P (Park) (if equipped) or N (Neutral) (automatic
transmissions) or the neutral position (manual transmission).
•The ignition switch is in the off position.
•All vehicle doors are closed.
•The driver’s safety belt is unbuckled.
•The headlamp control is in the
position.
WARNING:While the design allows you to deactivate your
Belt-Minder, this system is designed to improve your chances of
being safely belted and surviving an accident. We recommend you
leave the Belt-Mindersystem activated for yourself and others who
may use the vehicle. To reduce the risk of injury, do not
deactivate/activate the Belt-Minderfeature while driving the vehicle.

WARNING:If the red BRAKE warning lamp in the instrument
cluster remains illuminated after engine start up, this indicates a
system failure in the Full Power Brake System. Stop the vehicle safely
as soon as possible and seek service immediately.
Note:During normal driving the pump/motors may be heard
replenishing the accumulators; this is a normal function of the system.
Parking brake
Apply the parking brake whenever
the vehicle is parked. To set the
parking brake, pull handle up until it
snaps into the locked position.
WARNING:Do not use the
gearshift selector in place of
the parking brake. Always set the
parking brake fully AND make
sure the gearshift selector is in R
(Reverse) for vehicles equipped
with manual transmission, P
(Park)(if equipped)or N
(Neutral) for vehicles with
automatic transmission. Use of
wheel chocks is also
recommended in hilly or off-road
usage.
WARNING:Unexpected and possible sudden vehicle movement
may occur if these precautions are not taken.
When the parking brake is out of adjustment, seek service immediately.

POWER PARK (PARKING BRAKE) OPTION (IF EQUIPPED)
This feature uses a brake chamber mounted on the chassis to power a
spring-applied, hydraulically-released driveline parking brake. It is
controlled by a yellow, dash-mounted parking brake knob.
The Power Park Brake is controlled by the park brake dash-mounted,
yellow knob-type switch. The switch has three positions: apply (out),
neutral (central), and release (in). The switch is spring-loaded to return
to the neutral (central) position after being pushed or pulled.
There is no visual indication at the knob that the park brake is applied or
released; check the instrument cluster. If the
light is illuminated,
the parking brake is applied.
Applying the parking brake
To apply the parking brake, pull the yellow, dash-mounted parking brake
knob. A red light (
) in the instrument cluster should illuminate
indicating that the parking brake has been successfully set.
Note:If the
light blinks and a warning chime sounds when the
control knob is pulled, the parking brake is not functioning properly;
seek immediate service from your dealer. Refer toParking brake
warning systemin this section.
Releasing the parking brake
Note:Read and understand the following steps and perform them
whenever you prepare to drive the vehicle.
Note:The parking brake does not disengage unless sufficient system air
pressure is available.
Automatic transmissions - dash-mounted push button (Allison
3000 Series) and steering column-mounted (Allison 2200 and 2500)
gear selection:
1. With the engine running, press and hold the service brake pedal.
2. Select the appropriate drive gear.
3. Push and hold the yellow, dash-mounted parking brake knob until
the
light turns off, then release.
Manual transmissions - (TTC 7–speed, Eaton/Fuller 5–speed and
6–speed):
1. With the engine running, press and hold the service brake pedal.
2. Press and hold the clutch pedal.

Air brake reservoir draining
WARNING:Failure to drain air brake reservoirs can result in a
reduction or loss of braking ability due to fluid accumulation in
the reservoir and/or possible freeze-up during cold weather.
Drain all the air brake reservoirs
daily, completely to 0 psi/kPa, by
opening the draincock at the ends
of the tanks (where accessible.
Pull-chains are used when the
drains are undercab or otherwise
inaccessible). Close draincock after
complete draining. Air tanks
equipped with automatic moisture
ejector valves may also be drained
manually as required to maintain a
dry air system. Contact your dealer if you are unsure of the air reservoir
locations or the draining procedure.
Parking brake
WARNING:Do not use the gearshift selector in place of the
parking brake; unexpected and possible sudden vehicle
movement may occur if these precautions are not taken. Always set
the parking brake fully AND make sure the gearshift selector is in R
(Reverse) for vehicles equipped with manual transmission, N (Neutral)
for vehicles with automatic transmission (except Allison 2200
transmission) or P (Park) (Allison 2200 transmission).
If the service brakes should fail to operate while the vehicle is in motion,
you can make an emergency stop with the parking brake. Since the
parking brake only applies stopping power to the rear wheels, the
vehicle’s stopping distance greatly increases and the handling of the
vehicle is adversely affected. Repairs should be made immediately to an
inoperative air brake system circuit.

Parking brake control (knob)
Pull the yellow parking brake knob
out to apply the parking brake. Push
the knob in to release the parking
brake.
WARNING:This control is used for parking only. Do not leave
the vehicle unattended after setting the parking brake without
placing the transmission in R (Reverse) for manual transmission, N
(Neutral) for automatic transmission (except Allison 2200
transmission) or P (Park) (Allison 2200 transmission). Use of wheel
chocks is also recommended in hilly or off-road usage.
The
light illuminates and
remains illuminated (when the
ignition is turned to the on position)
until the parking brake is released.
Releasing spring brake with air pressure
The air system in all vehicles with spring-actuated rear wheel parking
brakes is equipped with a tank valve located on the supply or service air
tank for connection to an outside air supply. The valve permits the
system to be recharged with air from an outside source, releasing the
spring-actuated parking brakes. The vehicle may then be towed in an
emergency.
An outside air source can be used only if the protected system is in
operating condition. If air pressure cannot be restored in the protected
air system, the spring-actuated brakes must be released manually.

Note:Manual transmissions should be downshifted to the lowest gear
possible, without exceeding the maximum RPM limit of the engine. This
maximizes the exhaust brake’s retarding effect.
Note:Exhaust brakes operate effectively with automatic transmissions,
but performance varies with engine speed and the gear selected by the
transmission.
Note:Installing an exhaust or auxiliary brake does not necessarily
protect the engine from exceeding maximum governed speed. The
primary brakes should be used to make sure the engine never exceeds
maximum governed speed under any conditions.
WARNING:The exhaust brake is not recommended for use on
slippery or low traction road surfaces. Under these conditions a
loss of vehicle control could occur.
Exhaust brake operating characteristics
When you remove your feet from both the accelerator and clutch pedals
and the exhaust brake switch is in the on position, the exhaust brake is
activated. The following conditions should exist if the brake is operating
properly:
•A slight change in the sound of the engine when the exhaust brake is
activated.
•A smooth braking effect; do not expect a retarding effect similar to
sudden, hard application of the service brakes.
•The retarding force possibly felt acting against your body when the
brake is applied, depending on the grade and vehicle load. The brake’s
retarding force is actually preventing the vehicle from going much
faster.
•Engine temperature remains in the normal operating range.
•During a descent, the tachometer usually shows a drop in engine RPM
depending on the grade and the vehicle load.
•Road speed usually decreases when the exhaust brake is applied
during a descent, except when the vehicle is carrying a heavy load or
the grade is extremely steep. In these instances, you may need to
apply the service brakes occasionally.
