the condition of the battery.
 Have the vehicle fitted with four
snow tires or purchase a set of tire
chains for the rear tires. *
Ensure that all tires are the specified size
and brand, and that chains match the size
of the tires. *

wheels. ■
When installing tire chains
Before installing tire chains, make sure to
disable all functions of the vehicle height

limit specified for the tire chains being
used, or 30 mph (50 km/h), which-
ever is lower. ●
Avoid driving on bumpy road surfaces
or over potholes. ●
Avoid sudden acceleration, abrupt
steering, sudden br aking and shifting
operations that cause sudden engine
braking.
●
