tures.
• Engine oil
• Engine coolant
• Washer fluid
● Have a service technician ins pect the condition of the battery.
● 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.
Perform the following accordin g 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.

mulated on the exterior lights, ve hicle’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.
Accelerate the vehicle slowly, keep a safe distance between you and
the vehicle ahead, and drive at a reduced speed suitable to road con-
ditions.
Carry out the necessary preparations and inspections before
driving the vehicle in winter. Always drive the vehicle in a man-
ner appropriate to the prevailing weather conditions.

sound in a different tone for 20 more seconds.
