GMC Hummer H3 2008 Owner's Handbook Manual page 312

CAUTION
Avoid further tyre and wheel
damage by driving very slowly
to a level place and stopping.
Turn on your hazard warning
flasher.
Changing a tyre can cause
injury. The vehicle can slip off
the jack and injure you or other
people.
CAUTION
(Continued)
To help prevent the vehicle
from moving while changing
the flat tyre:
• Park on a firm, level surface.
• Set the park brake firmly.
• Place the automatic gear shift
in P (Park), or the manual
gear shift in 1 (First) or
R (Reverse).
• Make sure that the transfer
case is in a drive gear and not
in N (Neutral). Otherwise, the
vehicle will be free to roll even
if the automatic transmission
is in P (Park) or the manual
transmission is in gear.
• Turn off the engine.
Section 5
CAUTION
(Continued)
• Do not start the vehicle while
it is raised on the jack.
• Before jacking, have all pas-
sengers get out of the vehicle.
• Put blocks at the front and
rear of the tyre furthest away
from the one being changed.
