Winter driving tips
Carry out the necessary preparations and inspections before driving
the vehicle in winter. Always drive the vehicle in a manner appropri-
ate to the prevailing weather conditions.
■ Pre-winter preparations
●Use fluids that are appropriate to the prevailing outside tem-
peratures.
• Engine oil
• Engine/power control unit coolant
• Washer fluid
● Have a service technician inspec t the condition of the 12-volt
battery.
● Have the vehicle fitted with four snow tires or purchase a set
of tire chains for the front 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 th e climate control system fan,
remove any snow that has accumulated on the air inlet vents
in front of the windshield.

Exposure rules. This equipment has very low levels of RF energy that it
deemed to comply without maximum permissive exposure evaluation
(MPE). But it is desirable that it should be installed and operated with at least
20cm and more between the radiator and person’s body (excluding extremi-
ties: hands, wrists, feet and ankles).
This Category II radiocommunication device complies with Industry Canada
Standard RSS-310.

nal strength and surrounding objects, such as trains, transmitters, etc.
● When is used, automatic station selection may not be possi-
ble.
● The radio antenna is mounted on the rear roof. The antenna can be
removed from the base by turning it.
