inspection. Check all fuel and
vapor lines and hoses for proper

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.
First Engine Oil Change After
Every 160 000 km/100,000 Miles
Automatic transmission fluid and
filter change (normal service).
See Automatic Transmission
Fluid on page 10 12.
All wheel drive only: Transfer
case fluid change (normal
service). Check vent hose at
transfer case for kinks and
proper installation. Check to be
sure vent hose is unobstructed,
clear, and free of debris. During
any maintenance, if a power
washer is used to clean mud
and dirt from the underbody,
care should be taken to not
directly spray the transfer case
output seals. High pressure
water can overcome the seals
and contaminate the transfer
case fluid. Contaminated fluid
will decrease the life of the
transfer case and should be
replaced.
Spark plug replacement and
spark plug wires inspection.
An Emission Control Service.
First Engine Oil Change After
Every 240 000 km/150,000 Miles
