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 appropriate to the prevailing outside temperatures.
• Engine oil
• Engine coolant
• Washer fluid
• Have a service technician inspect the condition of the battery.
• Have the vehicle fitted with four snow tires or purchase a set of tire chains for the front tires (do not fit tire chains on to the rear tires).
Ensure that all tires are the same size 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 window or move a wiper that is frozen. 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.
• Check for and remove any excess ice or snow that may have accumulated on the exterior lights, vehicle’s roof, chassis, around the tires or on the brakes.
• Remove any snow or mud from the bottom of your shoes before getting in the vehicle.
- When driving the vehicle
Accelerate the vehicle slowly, keep a safe distance between you and the vehicle
ahead, and drive at a reduced speed suitable to road conditions.
- When parking the vehicle
Park the vehicle and move the shift lever to “P” without setting the parking brake.
The parking brake may freeze up, preventing it from being released. If necessary
block the wheels to prevent inadvertent sliding or creeping.
