Driving tips/Winter driving
WARNING
Snow can trap dangerous exhaust
gases under your vehicle. Keep
snow clear of the exhaust pipe and
from around your vehicle if you park
the vehicle in snow with the engine
running.
Refueling in cold weather
To help prevent moisture from forming in
the fuel system and the risk of its freezing,
use of an antifreeze additive in the fuel
tank is recommended during cold weather.
Use only additives that are specifically
designed for this purpose. When an
antifreeze additive is used, its effect lasts
longer if the tank is refilled whenever the
fuel level reaches half empty.
If your SUBARU is not going to be used
for an extended period, it is best to have
the fuel tank filled to capacity.
Driving on snowy and icy
roads
To prevent skidding and slipping, avoid
sudden braking, abrupt acceleration, high-
speed driving, and sharp turning when
driving on snowy or icy roads.
Always maintain ample distance between
your vehicle and the vehicle ahead of you
to avoid the need for sudden braking.
To supplement the foot brake, use the
engine brake effectively to control the
vehicle speed. (Shift into a lower gear
when necessary.)
Avoid shifting down abruptly. Such beha-
vior can cause the wheels to lock, possibly
leading to loss of vehicle control.
An anti-lock brake system (ABS) en-
hances your vehicle s braking perfor-
mance on snowy and icy roads. For
information on braking on slippery sur-
faces, refer to ABS (Anti-lock Brake
System) 7-35 and Vehicle Dynamics
Control system 7-38.
WARNING
Do not use the cruise control on
slippery roads such as snowy or icy
roads. This may cause loss of
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 wiper blades are frozen to the
windshield, use the defroster and the
temperature set for maximum warmth until
the wiper blades are completely thawed.
Refer to Climate control 4-1.
If your vehicle is equipped with a wiper
deicer, use it. It is helpful to thaw the
windshield wiper blades. Refer to Defog-
ger and deicer 3-114.
When driving in snow, if frozen snow starts
to stick on the surface of the windshield
despite wiper operation, use the defroster
and the temperature 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 Windshield washer 3-105.
