SAFETY SUMMARY

Individuals who decide to perform their own repairs should have proper training and limit repairs to components which will not af-
fect the safety of the vehicle or its occupants.

When replacement parts are required, it is strongly recommended that they are purchased through an authorized HUMMER 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 factory components are installed.

The installation of nonapproved accessories or conversions is not recommended as they could affect the vehicle’s driving charac-
teristics and personal safety. AM General LLC will not be liable for personal injury or damage to property resulting from the instal-
lation of nonapproved accessories or conversions 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.

Warnings, cautions, and notes are used throughout this service manual to assist service personnel in the performance of mainte-
nance actions. These statements are designed as reminders for trained and experienced service personnel.
