Snow chains
For technical reasons, the use of snow chains on

you removed, and install that in place of the
front tire that failed.
A WARNING
-After installing a spare tire, the tire pres­ sure must be checked as quickly as possible.
- Do not drive faster than 50 mph (80 km/h)
with a compact spare tire. Driving faster
than that increases the risk of an accident.
- To reduce the risk of an accident, avoid full­
throttle acceleration, heavy braking, and
fast cornering with the compact spare t ire.
- To reduce the risk of an accident, never drive
with more than one compact spare tire.

mounted on the compact spare wheel rim.

treme caution and careful dr iving .

- For technical reasons, the use of tire chains
on the spare tire is not permitted. If it is
necessary to drive with tire chains, the spare
wheel must be mounted on the front axle in
the event of a flat in a rear tire . The newly
ava ilable front wheel must then be installed
in place of the rear wheel w ith the flat tire.
Installing the tire chain before mounting
the wheel and tire is recommended.
- Loose items in the passenger compartment
can cause serious personal injury during
hard braking or in an accident. Never store
the inflatable spare tire or jack and tools in
