GMC 2007 Canyon - Manual (Page 445)

Automatic Transmission Shift Lock
Control System Check
{ CAUTION:
When you are doing this inspection, the
vehicle could move suddenly. If the vehicle
moves, you or others could be injured.
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 on page 130.
Be ready to apply the regular brake
immediately if the vehicle begins to move.
3. With the engine off, turn the ignition to ON,
but do not 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), contact your
GM Goodwrench
® dealer for service.
Ignition Transmission Lock Check
While parked, and with the parking brake set,
try to turn the ignition to LOCK in each shift
lever position.
• With an automatic transmission, the ignition
should turn to LOCK only when the shift
lever is in PARK (P). The ignition key should
come out only in LOCK.
• With a manual transmission, the ignition key
should come out only in LOCK.
Contact your GM Goodwrench ® dealer if service
is required.
