DESCRIPTION OF AVAILABLE RANGES

R (Reverse)
Press the «R» button to select reverse.
Completely stop the vehicle and let the engine
return idle before shifting from forward range «D»
to reverse «R» or 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.
NOTE
The automatic transmission does not have a
park «P» position. Select «N» (Neutral) and
apply parking brake when the vehicle is left
unattended. An audible alert will sound if the
engine is stopped and the parking brake is not
applied.
WARNING
Before leaving driver's seat, always put the
transmission in NEUTRAL and apply parking
brake.
The vehicle service brakes or park brake must
be applied whenever NEUTRAL is selected to
prevent unexpected vehicle movement.
Diesel engines should not be idled for extended
periods at "slow" idle. For extended idling,
engine should run at "fast" idle.
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
operation
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.
