A CAUTION:
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.
Brake-Transmission Shift Interlock (BTSI) Check (Automatic Transmission)
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. Before you start, be sure you have enough room
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.

NEUTRAL
(N), slowly remove foot pressure 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:
With the engine running, shift to PARK
(P). Then
release all brakes.
