Driving and Operating
The switch stays in this position
when the engine is running. The
transmission is also unlocked in this
position.
If the key is left in ON/RUN with the
engine off, the battery could drain
and the vehicle may not start.
3 (START) :
This is the position that
starts the engine. When the engine
starts, release the key. The ignition
returns to ON/RUN for driving.
Starting the Diesel
Engine
The diesel engine starts differently
than a gasoline engine.
Caution
If the steering wheel is turned
until it reaches the end of its
travel, and is held in that position
while starting the vehicle, damage
may occur to the hydraulic power
steering system and there may be
loss of power steering assist.
Move the shift lever to P (Park) or
N (Neutral). To restart the engine
when the vehicle is already moving,
use N (Neutral) only.
Caution
Do not try to shift to P (Park) if the
vehicle is moving. If you do, you
could damage the transmission.
Shift to P (Park) only when the
vehicle is stopped.
Starting the Engine
1. Turn the ignition key to
ON/RUN.
Observe the wait-to-start light.
See
.
This light may not come on if
the engine is warm.
2. If the wait-to-start light is on,
wait until this light goes off.
Turn the ignition key to START,
then release the ignition key.
The engine will continue to
crank until the engine starts.
The engine has a fast warm-up
glow plug system. The
wait-to-start light will illuminate
for a much shorter time than
most diesel engines, due to the
rapid heating of the glow plug
system.
Caution
If the wait-to-start light stays on
after starting the vehicle, the
vehicle may not run properly.
Have the vehicle serviced
right away.
3. If the engine does not start
after 15 seconds of cranking,
turn the ignition off. Wait
one minute for the cranking
motor to cool, then try the
same steps again.
If you are trying to start the engine
after you have run out of fuel, follow
