Driving and Operating
Caution
To reduce the chance of personal
injury and/or vehicle damage due
to engine overheating, never
leave the engine idling without an
alert driver present. If the engine
should overheat, as indicated by
the engine coolant temperature
gauge, immediate action is
required to correct the condition.
Continued operation of the
engine, even for a short time, may
result in a fire.
Starting the Engine
Do not keep the engine control
switch in the START position for
more than about 10 seconds.
Operating the starter for too long
might cause starter and battery
failure or may result in overheating.
When the engine does not start,
wait for 20 to 30 seconds and then
turn the engine control switch again.
Before starting the engine sit in the
driver seat, check that the parking
brake is firmly engaged, the selector
lever is in the P or N (P is preferred)
position and the shift indicator also
shows P or N, and firmly press the
brake pedal to start the engine. See
{
Warning
Do not keep the starter motor
engaged for more than
10 seconds at a time, or the
starter motor and the battery will
be adversely affected. Also, fire
may occur due to overheating.
Repeat the steps after a 20 to
30 seconds break.
1. Shift your selector lever to
P (Park) or N (Neutral). Your
engine will not start in any
other position-that's a safety
feature. To restart when you're
already moving, use
N (Neutral) only.
Do not try to shift to P (Park) if
your vehicle is moving. If you
do, you could damage the
transmission. Shift to P (Park)
only when your vehicle is
stopped.
2. Do not push the accelerator
pedal before starting your
engine. In some other vehicles
you might need to do this, but
because of your vehicle's
computer systems, you do not
need to.
3. Turn your ignition key to Start.
When the engine starts, let go
of the key. The idle speed will
go down as your engine
gets warm.
4. If it does not start right away,
hold your key in START. If it
doesn't start in 3 seconds,
push the accelerator pedal
about one-quarter of the way
down for 12 more seconds,
or until it starts.
