2.
3.
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.
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.
Brake-Transmission Shift Interlock (BTSI) 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. Before you start, be sure you have enough around the vehicle. It should
be parked on a level surface.
2. Firmly apply the parking brake (see “Parking Brake”
in the Index
if necessary).
NOTE: Be ready to apply the regular brake
immediately if the vehicle begins
to move.
3. With the engine off, turn the key to the RUN
position, but don’t start the engine. Without applying
the regular brake, try
to move the shift lever out
of PARK (P) with normal effort. If the shift lever
moves out of PARK (P), your vehicle’s BTSI
needs service.
Ignition Transmission Lock Check
While parked, and with the parking brake set, try to turn
the ignition key to
LOCK in each shift lever position.
0 The key should turn to LOCK only when the shift
lever is in PARK (P).
The key should come out only in LOCK.

from
the regular brake pedal. Do this until the vehicle is
held by the parking brake only.
To check the PARK (P) mechanism’s holding ability:
