Foglamp control (if equipped)
The headlamp control also operates
the foglamps. The foglamps can be
turned on only when the headlamp
control is in the
position and
the high beams are not turned on.
Pull headlamp control towards you
to turn foglamps on. The foglamp
indicator light
will illuminate.
AUXILIARY POWER POINT
The auxiliary power point is located
on the instrument panel.
Do not plug optional electrical
accessories into the cigarette lighter.
Use the power point.

2. Move the control in the direction
you wish to tilt the mirror.
3. Return to the center position to lock mirrors in place.
HEATED TELESCOPING TRAILER TOW MIRRORS
Manually pull the mirror outward or
inward as desired. Pull the mirrors
inward carefully when driving
through a narrow space.
MIRRORS
With the doors closed and the seat
adjusted for proper comfort, move
the mirrors to maximize rear
viewing area by adjusting the
western mirrors left or right as
required.
Adjust the auxiliary convex mirrors.
Convex mirrors are a ball-stud
design for precise adjustment to
maximize viewing area.

Reservoir selection
The number one service reservoir will at all times be selected as the
primary supply source for the MV-3. This is accomplished automatically
by the function of the dual circuit supply valve contained in the body of
the MV-3. Only in the event of a pressure drop of more than 207 kPa (30
psi) below that of the number two service reservoir will the dual circuit
supply valve shuttle and establish the front service reservoir as the
supply.
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:
²off-highway driving
²mountain driving
²heavy traffic
²high speed highway driving
It is not available with automatic transmissions.
The exhaust brake is a butterfly
type valve mounted in the exhaust
pipe. When the operator's foot is not
on the accelerator pedal and the
exhaust brake switch is in the ON
position, an air cylinder shuts the
butterfly valve, restricting the flow
of exhaust gases and retarding the
engine. This retarding action is
carried through the engine and drivetrain, slowing the vehicle and
reducing the need for frequent service brake applications.
Exhaust brakes are not intended for use as the primary braking system
during vehicle operation.

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:
²A slight change in the sound of the engine when the exhaust brake is
activated.
²Exhaust smoke appears normal.
²Engine temperature remains in the normal operating range.
²Road 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.
²During a descent, the tachometer usually shows a drop in RPM
depending on the grade and the vehicle load.
²Do not expect a retarding effect similar to sudden hard application of
the service brakes. The exhaust brake retards the vehicle with a
smooth braking effect.
²Depending on the grade and vehicle load, you may or may not feel the
retarding force acting against your body when the brake is applied.
The brake's retarding force is actually preventing the vehicle from
going much faster.
Make sure the exhaust brake is turned off before shutting off the engine.
Installing an exhaust or auxiliary brake should never allow the
engine to exceed maximum governed speeds under any
conditions. Refer to theStartingchapter.
Air brake reservoir draining
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.
