With cruise control, you can maintain a speed
of about 25 mph (40 km/h) or more without
keeping your foot on the accelerator. Cruise
control does not work at speeds below about
25 mph (40 km/h).
If you have an automatic transmission and you
apply your brakes, the cruise control will shut off.
If you have a manual transmission and you
apply your brakes or push the clutch pedal, the
cruise control will shut off.
{CAUTION:
Cruise control can be dangerous where
you cannot drive safely at a steady speed.
So, do not use your cruise control on
winding roads or in heavy traffic.
Cruise control can be dangerous on
slippery roads. On such roads, fast
changes in tire traction can cause
excessive wheel slip, and you could lose
control. Do not use cruise control on
slippery roads.
Setting Cruise Control
{CAUTION:
If you leave your cruise control on when
you are not using cruise, you might hit a
button and go into cruise when you do not
want to. You could be startled and even
lose control. Keep the cruise control switch
off until you want to use cruise control.
1. Move the cruise control switch to on.
2. Get up to the speed you want.
3. Press in the set button at the end of the lever
and release it.
4. Take your foot off the accelerator pedal. The
accelerator pedal will not go down.
147

Passing Another Vehicle While Using
Cruise Control
Use the accelerator pedal to increase your speed.
When you take your foot off the pedal, your
vehicle will slow down to the cruise control speed
you set earlier.
Using Cruise Control on Hills
How well your cruise control will work on hills
depends upon your speed, load and the steepness
of the hills. When going up steep hills, you may
want to step on the accelerator pedal to maintain
your speed. When going downhill, you may
have to brake or shift to a lower gear to keep your
speed down. Of course, applying the brake or
clutch takes you out of cruise control. Many drivers
find this to be too much trouble and don’t use
cruise control on steep hills.
If your vehicle is equipped with the exhaust brake
option and the exhaust brake is turned on, the
exhaust brake may come on and try to slow down
the vehicle to the set cruise control speed if the
vehicle has accelerated past the set cruise control
speed while going downhill.
Ending Cruise Control
There are four different ways to turn off the
cruise control:
•Step lightly on the brake pedal (manual and
automatic transmissions).
•Press the clutch pedal to the floor (manual
transmissions).
•Move the cruise switch to off, or
•Shift the transmission to NEUTRAL (N).
Erasing Speed Memory
When you turn off the ignition, your cruise control
set speed memory is erased.

Voltmeter Gage
When your engine is
running, the voltmeter
gage shows the
charging system
voltage.
Readings in either warning zone indicate a
possible problem in the electrical system.
Readings in the low warning zone may occur
when a large number of electrical accessories are
operating in the vehicle and the engine is left at
an idle for an extended period. This condition
is normal since the charging system may not be
able to provide full power at engine idle. As engine
speeds are increased, this condition should
correct itself because higher engine speeds allow
the charging system to create maximum power.You can only drive a short time on the battery.
Be sure to shut off the radio, the fan or any
unnecessary accessories and have the system
serviced.
Service Transmission Warning Light
If your vehicle has an Allison®automatic
transmission, certain transmission malfunctions
will turn this light on.
This light is located with
the auxiliary warning
lights in the center of the
instrument panel.
If this light comes on while you are driving, do not
use the transmission shift control or you may
lose forward gears. The computer for the
transmission senses a problem and chooses a
gear to stay in so that you can drive the vehicle in
that gear. You may not be able to drive as fast
or back up when this light is on.
168

Notice:If you continue driving your vehicle
after the transmission warning light comes on,
you could damage the transmission. While
this light is on, the transmission cannot
operate in all gears. If you attempt to shift
gears, the vehicle may not continue to move.
Do not attempt to shift gears while the
transmission warning light is on. Instead, drive
directly to an authorized dealer for service. If
you cannot drive to a dealer immediately, have
the vehicle towed.
Range Inhibit Warning Indicator
If your vehicle has an Allison 1000/2200/2300/
2500 series automatic transmission, a lighted bar
under the current gear selected will flash.
If your vehicle has an Allison 3000/3500
series automatic transmission, the current gear
selected on the pushbutton display will flash.
The flashing bar or gear selection indicates that
transmission range shifts may not occur.
For detailed information on shift inhibit limitations,
see the Allison Automatic Transmission
Operator’s Manual in your vehicle for further
information.
Brake System Warning Light
Your vehicle has either hydraulic or air brakes.
Each system has different warning lights.
Hydraulic Brake System
Warning Lights
Vehicles with hydraulic brake systems
have two brake system warning lights on the
instrument panel.
If the brake system
warning light comes on,
it means that the
fluid level in the master
cylinder reservoir is
low or there is another
problem with your
hydraulic brakes.
When it comes on, you will also hear a
warning tone.
169

Transmission Temperature Gage
If you have an automatic
transmission and this
gage, it is located above
the switchbank in the
center of the instrument
panel.
When your ignition is on, the gage shows the
temperature of the transmission oil. A reading in
the warning zone, the red area beginning at 300°F
(150°C), means you must stop driving and
check into the cause. One possible cause is a low
oil level in the transmission.
Notice:If you drive your vehicle with the
transmission temperature gage above normal
operating range, you can damage the
transmission. This could lead to costly repairs
that would not be covered by your warranty.
Do not drive your vehicle while the
transmission temperature gage reading is
above normal. See your dealer for service.
Exhaust Brake Indicator Light
If your vehicle is
equipped with an
exhaust brake, you will
have this light, located
above the climate
controls in the center of
the instrument panel.
The exhaust brake indicator light will come on and
stay on whenever the diesel engine exhaust brake
or exhaust restrictor is active. For more information,
seeDiesel Engine Exhaust Brake on page 112and
Exhaust Restrictor (Engine Warm-Up) on page 108.
Differential Lock Indicator Light
If your vehicle has this
feature, this light is
located in the center of
the instrument panel.
The light is on when the
rear differential lock
system is in use.
178

Traction Control System (TCS)
Your vehicle may have a traction control system
that limits wheel spin. This is especially useful
in slippery road conditions. The system operates
only if it senses that one or both of the rear wheels
are spinning or beginning to lose traction. When
this happens, the system applies the brake(s)
at the affected wheel(s).
The bottom light on the TCS on/off button will
come on when the TCS is limiting wheel spin.
You may feel or hear the system working, but this
is normal. The TCS will function at speeds up
to about 25 mph (42 km/h).
The TCS may operate on dry roads under some
conditions. When this happens, you may notice a
reduction in acceleration. This is normal and
doesn’t mean there’s a problem with your vehicle.
Examples of these conditions include a hard
acceleration in a turn, an abrupt upshift or downshift
of the transmission or driving on rough roads.When the light in the top of the TCS button is
on, the TCS is off and will not limit wheel
spin. Adjust your driving accordingly.
The light in the top of the TCS button will come
on if the TCS is turned off by pressing the
TCS on/off button.
The light may also come on if a problem has been
detected in either the traction control system or
the anti-lock brake system.
The traction control system automatically comes
on whenever you start your vehicle. To limit wheel
spin, especially in slippery road conditions, you
should always leave the system on. But you
can turn the traction control system off if you ever
need to. You should turn the system off if your
vehicle ever gets stuck in sand, mud or snow
and rocking the vehicle is required. SeeRocking
Your Vehicle to Get It Out on page 236for
more information.
