Starter Switch Check When
you are doing this check, the vehicle could
move suddenly.
If it does, you or others could be
injured. Follow the steps below.
1.
2.
3.
Before you start, be sure you have enough room
around the vehicle.
Firmly apply both the parking brake
(see “Parking
Brake” in the Index if necessary) and the regular brake.
NOTE: Do not use the accelerator pedal, and be
ready
to turn off the engine immediately if it starts.
On automatic transmission vehicles, try
to start the
engine in each gear. The starter should work only in
PARK (P) or NEUTRAL (N). If the starter works in
any other position, your vehicle needs service.
On manual transmission vehicles, put the shift lever
in NEUTRAL (N), push.the clutch down halfway
and
try to start the engine. The starter should work
only when the clutch is pushed down
all the way to
the floor.
If the starter works when the clutch isn’t
pushed all the way down, your vehicle needs service.

When you are doing this check, the vehicle could
move suddenly.
If it does, you or others could be
injured. Follow the steps below.
1.
2.
3.
Before you start, be sure you have enough
room around the vehicle. It should be parked
