Maintenance
Winter Tires
If driving on snowy or frozen roads, mount all season marked M+S tires, snow tires, or tire
chains; reduce speed; and maintain sufficient distance between vehicles when driving.
Be particularly careful wh en operating the steering wheel or brakes to prevent
skidding.
Use tire chains, snow tires, or all season tires when necessary or according to the law.
When mounting, refer to the following points.
For winter tires:
• Select the size and load ranges that are the same as the original tires.
• Mount the tires to all four wheels.
For tire chains:
• Install them on the front tires only.
• Because your vehicle has limited tire clea rance, we strongly recommend using the
chains listed below:
• Follow the chain manufactur er’s instruction when installing. Mount them as
tightly as you can.
• Check that the chains do not touc h the brake lines or suspension.
• Drive slowly.
