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 or purchase a set of
tire chains for the rear tires.
Ensure that all tires are the same size and brand, and that chains match
the size of the tires.
