detection of a service issue relating to clutch, filter or
fluid life. The appearance of the indicator (lit steadily,
flashing, etc.) varies for each of the conditions
monitored by the system. Refer to appendix C for

Illuminated at startup for a bulb check, this indicator
will then be turned off if no service conditions exist.

DESCRIPTION OF AVAILABLE RANGES

R (Reverse)
Press the «R» button to select reverse. Completely
stop the vehicle and let the engine return idle before

from reverse to forward range. The reverse warning
signal will be activated when this range is selected.
N (Neutral)
Use this position to start the engine. Select «N»
(Neutral) when checking vehicle accessories and for
extended periods of engine idle operation; parking
brake must then be applied. The pushbutton shift
selector automatically select «N» (Neutral) when the
ignition switch is turned On.

«P» position. Select «N» (Neutral) and apply

WARNING
The vehicle service brakes or park brake must be
applied whenever NEUTRAL is selected to
prevent unexpected vehicle movement.
CAUTION
Diesel engines should not be idled for extended
periods at "slow" idle. For extended idling, engine
should run at "fast" idle.
CAUTION
Do not allow your vehicle to "coast" in neutral «N».
This practice can result in transmission damage.
Also, no engine braking is available in neutral.
D (Drive)
Use this position for all normal driving conditions.
After touching this pad, the vehicle will start in first or
second range and will automatically upshift to a
higher range as output speed increases. As the
vehicle slows down, output speed decreases, the
transmission automatically downshifts to the correct
range. If a locked brake or a slick surface condition
should occur, the TCM (Transmission Control
Module) will command
(disconnect lockup) and inhibit downshift for a period
of time or until normal wheel speed has been
restored.
NOTE
IMPORTANT: Brake pedal must be applied when
selecting «D» (Drive) otherwise the transmission
will stay in «N» (Neutral).
NOTE
The transmission should normally be allowed to
shift by itself, but manual shifting can be done as
described below.
