tures.
• Engine oil
• Engine coolant
• Washer fluid
● Have a service technician inspect the level and specific gravity of
battery electrolyte.
● Have the vehicle fitted with four snow tires.
Ensure that all tires are the specified size and the same brand.

bumper exhaust diffusers until they have cooled sufficiently, as touching hot exhaust
pipes and diffusers can cause burns.
