Brake-Transmission Shift Interlock -= BTSI
1. Before you start, be sure you have enough room around the vehicle. It
should be parked on a level surface.
2. Firmly apply both 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.
Steering Column Lock
While parked, and with the parking brake set, try to turn the key to LOCK
in each shift lever position.
With an automatic transmission, the key should turn to LOCK only
when the shift lever is in PARK (P).
With a manual transmission, the key should turn to LOCK only when
the shift lever is in
REVERSE (R).
On vehicles with a key release button, try to turn the key to LOCK without
pressing the button. The
key should turn to LOCK only with the key button
depressed.
On vehicles with
a key release lever, try to turn the key to LOCK without
pressing the lever. The key should turn
to LOCK only with the key lever
depressed.
On all vehicles, the key should come
out only in LOCK.

0 To check the parking brake: With the engine running and transmission
in NEUTRAL
(N), slowly remove foot pressure from the regular brake
pedal.
Do this until the vehicle is held by the parking brake only.
0 To check the PARK (P) mechanism’s holding ability: Shift to PARK
(P). Then release all brakes.

Part C: Periodic Maintenance Inspections
Listed below are inspections and services which should be performed at
least twice a year (for instance, each spring and fall).
You should let your
GM dealer’s service department or other qualified service center do these
jobs.
Make sure any necessary repairs are completed at once.
Steering and Suspension lnspection
Inspect the front and rear suspension and steering system for damaged,
loose or missing parts, signs
of wear, or lack of lubrication. Inspect power
steering lines and hoses for proper hookup, binding, leaks, cracks, chafing,
etc. (On vehicles equipped with manual steering gear, check
for seal
leakage.)
Exhaust System lnspection
Inspect the complete exhaust system. Inspect the body near the exhaust
system.
Look for broken, damaged, missing or out-of-position parts as well
as open seams, holes, loose connections, or other conditions which could
cause
a heat build-up in the floor pan or could let exhaust fumes into the
vehicle.
See “Engine Exhaust’’ in the Index.
Accelerator Control System
On gasoline engines, lubricate the pivot at the TBI throttle lever stud with
engine oil.
Do not oil any accelerator or cruise control cables. Replace any
cables that have high effort or excessive wear.
Drive Axle Service
Check readfront axle fluid level and add as needed. Check constant velocity
joints and axle seals for leaking.
Transfer Case (Four- Wheel Drive) Inspection
Every 12 months or at oil change intervals, check front axle and transfer
case and add lubricant when necessary. Oil the control lever pivot point and
all exposed control linkage. Check vent hose
at transfer case for kinks and
proper installation. More frequent lubrication
may be required on off-road
use.
