• Full-time AWD vehicles must be
tested on a special four wheel
chassis dynamometer.
• A full-time AWD vehicle should not
be tested on a FWD roll tester. If a
FWD roll tester must be used, per-
form the following:
1. Check the tire pressures recom-
mended for your vehicle.
2. Place the front wheels on the roll
tester for a speedometer test as
shown in the illustration.
3. Release the parking brake.
4. Place the rear wheels on the tem-
porary free roller as shown in the
illustration.
WARNING - Jacked
vehicle
While the full-time AWD vehicle
is being raised on a jack, never
start the engine or cause the
tires to rotate.
There is the danger that rotating
tires touching the ground could
cause the vehicle to go off the
jack and to jump forward.

WARNING - Replacement
Tires
When replacing tires and
wheels, be sure all four tires are
the same size, type, tread and
have the same load-carrying
capacity as the original equip-
ment tires. Installing replace-
ment tires that vary from the
original equipment tires can
negatively effect vehicle han-
dling and can increase the risk
of an accident.
