Failure to do so may result in a loss of 
vehicle control and cause death or seri-
ous injury.
●Use tires of the specified size.
●Maintain the recommended level of air 
pressure.
●Do not drive in excess of 75 mph (120 
km/h), regardless of the type of snow 
tires being used.
●Use snow tires on all, not just some 
wheels.
■Driving with tire chains (vehicles with

Observe the following precautions to 
reduce the risk of accidents.
Failure to do so may result in the vehicle 
being unable to be driven safely, and may 
cause death or serious injury.
●Do not drive in excess of the speed 
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 braking and shifting 
operations that cause sudden engine 
braking.
●Slow down sufficiently before entering 
a curve to ensure that vehicle control is 
maintained.
●Do not use LTA (Lane Tracing Assist) 
system.
