Driving tips/Winter driving
vehicle control.
CAUTION
Avoid prolonged continuous driving
in snowstorms. Snow will enter the
engine
’
s intake system and may
hinder the airflow, which could re-
sult in engine shutdown or even
breakdown.
!
Wiper operation when snowing
Before driving in cold weather, make sure
the wiper blades are not frozen to the
windshield or rear window.
If the front wiper blades are frozen to the
windshield, use the defroster with the
airflow control dial in the
“ ”
position
and the temperature control dial set for
maximum warmth until the wiper blades
are completely thawed out. For details,
refer to the following section.
.
For the manual climate control system,
refer to
“
Defrosting or defogging the
windshield
” F
4-5.
.
For the automatic climate control sys-
tem, refer to
“
Control panel
” F
4-8.
If your vehicle is equipped with a wind-
shield wiper deicer, it is helpful to thaw the
windshield wiper blades. Refer to
“
Defog-
ger and deicer
” F
3-47.
If the rear wiper blade is frozen to the rear
window, use the rear window defogger.
Refer to
“
Defogger and deicer
” F
3-47.
When driving in snow, if frozen snow starts
to stick on the surface of the windshield
despite wiper operation, use the defroster
with the airflow control dial in
“ ”
and the
temperature control dial set for maximum
warmth. After the windshield gets warmed
enough to melt the frozen snow on it,
wash it away using the windshield washer.
Refer to
“
Washer
” F
3-37.
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.
We recommend use of non-freezing type
wiper blades (winter blades) during the
seasons you could have snow and freez-
ing 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, non-
freezing 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-freez-
ing type wiper blades is over, replace
them with standard wiper blades.
