Pay Attention to the Way the Steering
Wheel Turns and Feels
On snowy roads, water and snow splashed
up by the tires can freeze and accumulate
inside the fenders, making the steering
wheel hard to turn. From time to time, get
out of the vehicle and remove any
accumulated snow.
Do not use a sharp implement to remove
snow. Sharp edges could damage rubber
parts.
Check the Brakes from Time to Time
When the vehicle is driven or parked on a
snowy surface, ice can form on the brakes,
decreasing their effectiveness. From time to
time while you are driving, press the brake
pedal lightly and check the effectiveness of
the brakes. Pay attention to vehicles both
ahead of and behind you when checking the
brakes in this way.
When you want to free the vehicle from
snow where the tires may slip slightly by
increasing the engine speed, you can press
the ESC OFF switch to disable just the
anti-slip regulation (ASR).
Also, check the effectiveness of the brakes
as soon as possible when starting to drive
the vehicle after it has been parked. If the
brakes do not work well, drive slowly and
gently press the brake pedal several times
until the brakes dry out and start working
normally.
Parking in Cold Regions
When snow collects around the wheels and
the lights, try to remove it before night
falls.
Do not apply the parking brake in extremely
cold weather, such as in temperatures or at
below 0°C (32°F). If you leave the parking
brake applied, the wires and brake shoes
could freeze up, making it impossible for
you to release the parking brake. Be sure to
park the vehicle in gear.
Be sure to put chocks against the tires.
Whenever possible, park in a garage to help
prevent parts from freezing up and to help
make the engine easy to start.
Warning
If you park in a place where there is a lot
of snowfall, snow accumulating around
the vehicle could limit ventilation.
Running the engine with the vehicle in
these conditions could cause exhaust

gases to enter the cabin, resulting in
carbon monoxide poisoning. Take
preventive action by, for example,
clearing the snow around the vehicle.
You and others could be seriously injured.
Do not park under trees or under the eaves
of a building. Chunks of ice could fall on the
vehicle if you park in such a place.
Cleaning the Vehicle after Driving on
Snowy Roads
The vehicle speed sensors are fitted on
the wheels. When removing snow, ice,
and other incrustation, take great care
not to damage the components.
Do not use a sharp implement to remove
snow. Sharp edges could damage rubber
parts.
Remove snow that has stuck to the inside of
the fenders and to the brake hoses.
Otherwise, it may damage components.
After driving on a salted road, wash the
underside of the vehicle as soon as possible
to prevent the salt from causing rust.
Spraying water under high pressure is an

effective way to get the salt off.
