Driving tips/Winter driving

Snow stuck on the wiper arm prevents the
wiper from working effectively. If snow is
stuck on the wiper arm, pull off the road to
a safe place, then remove it. If you stop
the vehicle at road side, use the hazard
warning flasher to alert other drivers.
Refer to “Hazard warning flasher” F3-8.
We recommend use of non-freezing type
wiper blades (winter blades) during the
seasons you could have snow and freezing temperatures. Blades of this type give
superior wiping performance in snowy
conditions. Be sure to use blades that
are suitable for your vehicle.

CAUTION
During high-speed driving, nonfreezing type wiper blades may not
perform as well as standard wiper
blades. If this happens, reduce the
vehicle speed.

NOTE
When the season requiring non-freezing type wiper blades is over, replace
them with standard wiper blades.

& Corrosion protection
Refer to “Corrosion protection” F10-4.

(e) Construction
(f) Manufacturer
(g) Brand (tread pattern)

It also may be dangerous and
lead to loss of vehicle control,
and it can lead to an accident.
. Do not use a combination of
radial, belted bias or bias tires
since it may cause dangerous
handling characteristics and lead
to an accident.
Your vehicle is equipped with “summer
tires” as original equipment, which are
inadequate for driving on slippery roads
such as on snow-covered or icy roads.
When you choose to install winter tires on
your vehicle, be sure to use the correct tire
size and type. You must install four winter
tires that are of the same size, construction, brand and load range and you should
never mix radial, belted bias or bias tires
since this may result in dangerous handling characteristics. When you choose a
tire, make sure that there is enough
