Tire chains
Since the sidewalls of radial tires are
thinner, they can be damaged by mounting some types of snow chains
on them. Therefore, the use of snow
tires is recommended instead of snow chains. Do not mount tire chains on ve‐
hicles equipped with aluminum wheels;
snow chains may cause damage to the wheels. If snow chains must be used,
use wire-type chains with a thickness
of less than 12 mm (0.47 in). Damage
to your vehicle caused by improper
snow chain use is not covered by your
vehicle manufacturers warranty.
Install tire chains only on the front tires.
CAUTION
•Make sure the snow chains are thecorrect size and type for yourtires. Incorrect snow chains cancause damage to the vehicle bodyand suspension and may not becovered by your vehicle manufac‐turer warranty. Also, the snowchain connecting hooks may bedamaged from contacting vehiclecomponents causing the snowchains to come loose from the tire.Make sure the snow chains areSAE class "S" certified.
•Always check chain installation forproper mounting after driving ap‐proximately 0.5 to 1 km (0.3 to 0.6miles) to ensure safe mounting.Retighten or remount the chains ifthey are loose.
Chain installation
When installing chains, follow the man‐
ufacturer's instructions and mount them as tightly as you can. Drive slowly
with chains installed. If you hear the
chains contacting the body or chassis, stop and tighten them. If they still
make contact, slow down until it stops.
Remove the chains as soon as you be‐ gin driving on cleared roads.
WARNING
nMounting chains
When mounting snow chains, parkthe vehicle on level ground awayfrom traffic. Turn on the vehicleHazard Warning flashers and place atriangular emergency warning devicebehind the vehicle if available. Al‐ways place the vehicle in P (Park),apply the parking brake and turn offthe engine before installing snowchains.
WARNING
nTire chains
•The use of chains may adverselyaffect vehicle handling.
•Do not exceed 30 km/h (20 mph)or the chain manufacturer’s rec‐ommended speed limit, whicheveris lower.
