Services — Severe
a) Check all fuel and vapor lines
and hoses for proper hook‐up,
routing, and condition. Check that
the purge valve, if the vehicle has
one, works properly. Replace as
needed.
b) Or every four years, whichever
comes first.
c) Do not directly power wash 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.
d) Or every five years, whichever
comes first. See Cooling System on
page 10‑15.
e) Or every 10 years, whichever
comes first. Inspect for fraying,
excessive cracking, or damage;
replace, if needed.

Additional
Maintenance and Care
Your vehicle is an important
investment and caring for it
properly may help to avoid
future costly repairs. To maintain
vehicle performance, additional
maintenance services may be
required. It is recommended
that your dealer perform these
services — their trained dealer
technicians know your vehicle
best. Your dealer can also
perform a thorough assessment
with a multi‐point inspection to
recommend when your vehicle may
need attention. The following list is
intended to explain the services
and conditions to look for that may
indicate services are required.
