SAFETY SUMMARY
Individuals who decide to perform their own repairs should
have proper training and limit repairs to components which
will not affect the safety of the vehicle or its occupants.
When replacement parts are required, it is strongly recom-
mended that they are purchased through an authorized HUM-
MER dealer. It is essential that replacement parts meet or
exceed manufacturer’s specifications. Vehicle performance
and personal safety may be impaired if other than original fac-
tory components are installed.
The installation of nonapproved accessories or conversions is
not recommended as they could affect the vehicle’s driving
characteristics and personal safety. AM General LLC will not
be liable for personal injury or damage to property resulting
from the installation of nonapproved accessories or conver-
sions to the HUMMER H1.
Following the safety precautions as prescribed throughout this
manual may greatly reduce the risks of personal injury and
damage to the vehicle. However, it is unlikely that AM General
LLC will account for all possibilities.

tenance actions. These statements are designed as reminders
for trained and experienced service personnel.
