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.

330 SERVICE AND MAINTENANCE
‐Any vehicle consistently
operated in a high sand or dust
environment such as those used
on oil pipelines and similar
applications.
. Vehicles that are regularly used for
short trips of 6 kilometers or less
If your vehicle has an Oil Life
Indicator, the indicator will show
you when to change the oil and
filter. Under severe conditions the
indicator may come on before
10 000 km/6,000 mi. The indicator
won't detect dust in the oil, so if
you drive in a dusty area you may
have to change the oil and filter
sooner than every 10 000 km/
6,000 mi.
Note: All vehicles with rear-wheel
drive —change driveline axle oil
every 30 000 km/19,000 mi if
vehicle is used for towing
purposes.
* Footnote: Under extreme driving
conditions listed above, it may be
necessary to replace your spark
plugs at more frequent intervals.
For further assistance in
determining the most suitable service maintenance intervals for
your vehicle, please contact your
authorized GM Dealer.
