Regulations regarding the use of tire
chains vary depending on location and
type of road. Always check local regu-
lations before installing chains.
■Tire chain installation
Observe the following precautions when
installing and removing chains:
●Install and remove tire chains in a safe
location.
●Install tire chains on the front tires only.
Do not install tire chains on the rear tires.
●Install tire chains on fr ont tires as tightly as
possible. Retighten chains after driving
1/4 1/2 mile (0.5 1.0 km).
●Install tire chains following the instruc-
tions provided with the tire chains.
To enable the windshield wipers to be
lifted when heavy snow or icy condi-
tions are expected, change the rest
position of the windshield wipers from
the retracted position below the hood
to the service position using the wiper
lever. ( P.208) 
Specific design characteristics give
it a higher center of gravity than
ordinary passenger cars. This vehi-
cle design feature causes this type
of vehicle to be more likely to roll-
over. And, utility vehicles have a sig-
nificantly higher rollover rate than
other types of vehicles.
 An advantage of th e higher ground
clearance is a better view of the
road allowing you to anticipate
problems.
 It is not designed for cornering at
the same speeds as ordinary pas-
senger cars any more than
low-slung sports cars are designed
to perform satisfactorily under
off-road conditions. Therefore,
sharp turns at excessive speeds may
cause the vehicle to rollover.
