Instrument Panel Cluster
Your instrument cluster is designed to let you know at a glance how your vehicle is running. You will know how fast
you are going, about how much fuel you have and many other things you will need to know to drive safely and
economically.

Canada, Light Duty Automatic and Manual Transmission Clusters similar.

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 is not able to provide full power at
engine idle. As engine speeds are increased, this
condition should correct itself as higher engine speeds
allow the charging system to create maximum power.
You can only drive for a short time with the reading
in either warning zone. If you must drive, turn off
all unnecessary accessories.
Readings in either warning zone indicate a possible
problem in the electrical system. Have the vehicle
serviced as soon as possible.
Up-Shift Light
(Manual Transmission)
This light is used on
some models with
manual transmissions.
The shift indicator light will show you when to shift to
the next highest gear, and will help you get the best fuel
economy.
Brake System Warning Light
With the ignition on, the brake system warning light will
ash when you set the parking brake. The light will ash if
the parking brake doesn’t release fully. If you try to drive
with the parking brake engaged, a chime will sound when
the vehicle speed is greater than 3 mph (5 km/h).
Your vehicle’s hydraulic brake system is divided into
two parts. If one part isn’t working, the other part can
still work and stop you. For good braking, though,
you need both parts working well.
If the warning light comes on and a chime sounds there
could be a brake problem. Have your brake system
inspected right away.
This light should come on briey when you turn the
ignition key to RUN. If it doesn’t come on then, have it
xed so it will be ready to warn you if there’s a problem.

on features for vehicles without DIC buttons.
If your vehicle has an Allison Transmission
®and the shift
lever is in the MANUAL MODE (M) position, the DIC will
display the current gear range. The DIC will also display
the gear range as it is shifted up or down. For example,
if the gear range is currently set to 6, the DIC will display
(6)54321.When the gear range is shifted down one
time, the DIC will display 6 (5)4321.SeeAutomatic
Transmission Operation on page 2-26for more
