152 Driving and Operating
Before Sitting in the Driver s Seat
Remove snow and ice from your
shoes when getting into the vehicle.
If you try to drive with snow on your
shoes, your shoes would slip on the
pedals and you would not be able to
press the pedals properly, meaning
that your driving would be
inconsistent. Also, the cabin could
become more humid, causing the
glass to fog up.
Check Fuel Level
Fuel consumption increases when
tire chains are used. Determine how
much fuel you need to reach your
destination and fill up the tank in
advance. Refer to Fuel for Diesel
Engines 0 227.
Removing Snow from Glass
and Underbody
Do not use a sharp implement to
remove snow. Sharp edges could
damage rubber parts.
To maintain an adequate field of
view, use a plastic scraper to
remove snow and frost from the
glass surfaces. By using a plastic
scraper, you can remove the snow
and frost without scratching the
glass. At this time, check whether
the wiper blades are frozen onto the
glass.
Also, look under the vehicle and
remove any lumps of ice that are
stuck to the underbody. Be careful
not to damage components.
Driving on Snowy or Frozen
Roads
On slippery roads, never accelerate
rapidly, brake hard, decelerate
rapidly or make sharp turns of the
steering wheel.
There is a risk of reduced grip
between the tires and road surface
and of increased braking distances.
The danger of icy road surfaces is
particularly great on bridges, in
shady places and where there are
puddles.
Keep your speed down and be sure
to use tire chains or winter tires on
snowy or frozen road surfaces.
Use engine brakes together with the
foot brakes to decelerate. Using the
exhaust brake on a slippery road
surface could cause the tires to slip.
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.
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.
Also, check the effectiveness of the
brakes as soon as possible when
starting to drive the vehicle after it
