Owner Checks and Services
Starter Switch Check
{WARNING:
When you are doing this inspection, the vehicle
could move suddenly. If the vehicle moves, you or
others could be injured.
1. Before starting this check, be sure there is enough room around the vehicle.
2. Firmly apply both the parking brake and the regular brake. See Parking Brake on page 3‑30.
Do not use the accelerator pedal, and be ready to
turn off the engine immediately if it starts.
3. For automatic transmission vehicles, try to start the engine in each gear. The starter should work only
in P (Park) or N (Neutral). If the starter works in any
other position, your vehicle needs service.
For manual transmission vehicles, put the shift
lever in Neutral, push the clutch pedal down
halfway, and try to start the engine. The starter
should work only when the clutch pedal is pushed
down all the way to the floor. If the starter works
when the clutch pedal is not pushed all the way
down, your vehicle needs service.

parking brake.
.To check the parking brake's holding ability: With
the engine running and the transmission in
N (Neutral), slowly remove foot pressure from the
regular brake pedal. Do this until the vehicle is held
by the parking brake only.
.To check the P (Park) mechanism's holding ability:
With the engine running, shift to P (Park). Then
release the parking brake followed by the regular
brake.
