Hummer H2 2007 Dismantling Manual page 2

Provide additional support when a vehicle is on a hoist in the following ways:
• Before removing parts, support the opposite end. This helps prevent the vehicle
from slipping off.
• Before removing major components, chain the vehicle frame to the hoist pads at
the same end as the removal. This helps avoid a tip-off.
Disconnect the battery prior to fluid removal and dismantling in order to reduce risk of
fire and personal injury.
Always wear safety goggles when working with fuel in order to protect the eyes from
splash.
Gasoline or gasoline vapors are highly flammable. A fire could occur if an ignition
source is present. Never drain or store gasoline or diesel fuel in an open container, due
to the possibility of fire or explosion. Have a dry chemical (Class B) fire extinguisher
nearby.
Relieve the fuel system pressure before dismantling fuel system components in order to
reduce the risk of fire and personal injury.
Drain the fuel from the complete system, including injector nozzle(s), the fuel pump, all
fuel pipes, and the fuel tank. Draining the fuel will reduce the risk of fire and personal
injury.
Provide proper ventilation when working with fuel in enclosed areas where fuel vapors
can collect. The lack of adequate ventilation may result in personal injury.
This vehicle has a Supplemental Inflatable Restraint (SIR), "airbag" system. When
performing disassembly on or near the SIR components or the SIR wiring, refer to
cautions below. Failure to follow the cautions could cause airbag deployment or
personal injury.
• Be careful when handling a SIR sensor. Do not strike or jolt a SIR sensor.
• Do not carry the inflator module by the wires or connector on the inflator module.
• Make sure the airbag opening points away from you.
• When storing an undeployed inflator module, make sure the airbag opening
points away from the surface on which the inflator module rests.
• Provide free space for the airbag to expand in case of an accidental deployment.
