General Information
Notice: Maintenance
intervals, checks, inspections,
recommended fluids, and
lubricants are necessary to
keep this vehicle in good
working condition. Damage
caused by failure to follow
scheduled maintenance might
not be covered by the vehicle
warranty.
As the vehicle owner, you are
responsible for the scheduled
maintenance in this section. We
recommend having your dealer
perform these services. Proper
vehicle maintenance helps to
keep the vehicle in good working
condition, improves fuel economy,
and reduces vehicle emissions for
better air quality. Because of all the different ways
people use vehicles, maintenance
needs vary. The vehicle might need
more frequent checks and services.
Please read the information under
Scheduled Maintenance. To keep
the vehicle in good condition, see
your dealer.
The maintenance schedule is for
vehicles that:
.Carry passengers and cargo
within recommended limits on
the Tire and Loading Information
label. See
Vehicle Load Limits
on page 9‑23.
.Are driven on reasonable road
surfaces within legal driving
limits.
.Are driven off-road in the
recommended manner. See
Off-Road Driving on page 9‑7.

The U.S. Environmental
Protection Agency or the
California Air Resources Board
has determined that the failure
to perform this maintenance
item will not nullify the emission
warranty or limit recall liability
prior to the completion of the
vehicle's useful life. We,
however, urge that all
recommended maintenance
services be performed at the
indicated intervals and the
maintenance be recorded.
