Buick 2009 Enclave - Manual (Page 376)

Ignition Transmission
Lock Check
While parked, and with the parking
brake set, try to turn the ignition to
LOCK/OFF in each shift lever
position.
• The ignition should turn to
LOCK/OFF only when the shift
lever is in P (Park).
• The ignition key should come
out only in LOCK/OFF.
Contact your dealer/retailer if
service is required.
Parking Brake and Automatic
Transmission P (Park)
Mechanism Check
{ CAUTION
When you are doing this check,
the vehicle could begin to move.
You or others could be injured
and property could be damaged.
Make sure there is room in front
of the vehicle in case it begins to
roll. Be ready to apply the regular
brake at once should the vehicle
begin to move.
Park on a fairly steep hill, with the
vehicle facing downhill. Keeping
your foot on the regular brake, set
the 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.
Contact your dealer/retailer if
service is required.
Underbody Flushing Service
At least every spring, use plain water
to flush any corrosive materials from
the underbody. Take care to clean
thoroughly any areas where mud
and other debris can collect.
Tire Sealant and
Compressor Kit
If the vehicle has a Tire Sealant and
Compressor Kit, check the sealant
expiration date printed on the
instruction label of the kit at least
once a year. See your dealer/retailer
for a replacement canister.
