Winter driving tips
Carry out the necessary preparations and inspections before driving the 
vehicle in winter. Always drive the vehicle in a manner appropriate to the 
prevailing weather conditions. 
■ Pre-winter preparations
●Use fluids that are appropria te to the prevailing outside tempera-
tures. 
• Engine oil
• Engine coolant
• Washer fluid
● Have a service technician inspect th e 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 si ze and brand, and that chains match 
the size of the tires.
■ Before driving the vehicle
Perform the following according  to the driving conditions. 
● Do not try to forcibly open a w indow or move a wiper that is fro-
zen. Pour warm water over the frozen  area to melt the ice. Wipe 
away the water immediately to prevent it from freezing. 
● To ensure proper operation of the climate control system fan, 
remove any snow that has accumulated on the air inlet vents in 
front of the windshield. 
● Remove any ice that has accumul ated on the vehicle chassis. 
● Periodically check for and remove any excess ice or snow that 
may have accumulated in the wheel well or on the brakes.
