Buick 2010 Enclave - Manual (Page 262)

9-18 Driving and Operating
Ignition Positions
The ignition switch has four different
positions.
In order to shift out of P (Park), the
ignition must be in ON/RUN or
ACC/ACCESSORY and the brake
pedal must be applied.
Notice: Using a tool to force the
key to turn in the ignition could
cause damage to the switch or
break the key. Use the correct
key, make sure it is all the way in,
and turn it only with your hand.
If the key cannot be turned by
hand, see your dealer/retailer.
(
(LOCK/OFF): This position locks
the ignition and transmission. The
key can be removed in LOCK/OFF.
The shift lever must be in P (Park)
to turn the ignition switch to
LOCK/OFF.
The steering can bind with the
wheels turned off center. If this
happens, move the steering wheel
from right to left while turning the
key to ACC/ACCESSORY. If this
doesn't work, then the vehicle
needs service.
ACC (ACC/ACCESSORY): This is
the position in which you can
operate the electrical accessories or
items plugged into the accessory
power outlets. This position unlocks
the ignition and steering wheel. Use
this position if the vehicle must be
pushed or towed.
R
(ON/RUN): This position can be
used to operate the electrical
accessories and to display some
instrument panel warning and
indicator lights. The switch stays in
this position when the engine is
running. The transmission is also
unlocked in this position. If you
leave the key in the ACC/
ACCESSORY or ON/RUN position
with the engine off, the battery could
be drained. You may not be able to
start the vehicle if the battery is
allowed to drain for an extended
period of time.
/
(START): This is the position
that starts the engine. When the
engine starts, release the key. The
ignition switch will return to ON/RUN
for driving.
