Catalytic Converter
291
Driving Tips8
NOTEDue to the expansion and contraction
of the metals used in the manufacture
of the exhaust system, you may hear a
crackling sound coming from the
exhaust system for a short time after
the engine has been shut off. This
sound is normal.
8-4. Catalytic ConverterThe catalytic converter is installed in the
exhaust system. It serves as catalyst to
reduce HC, CO and NOx in exhaust
gases, thus providing cleaner exhaust. To avoid damage to the catalytic
converter:

Use only unleaded gasoline. Even a
small amount of leaded gasoline will
damage the catalytic converter.
 Never start the engine by pushing or
pulling the vehicle.
 Avoid racing the engine.
 Never turn off the ig nition switch while
the vehicle is moving.
 Keep your engine tuned-up. If you feel
the engine running rough (misfiring, back-
firing or incomplete combustion), have
your vehicle checked and repaired by an
authorized SUBARU dealer.
 Do not apply undercoating or rust
prevention treatment to the heat shield of
catalytic converter and the exhaust
system.
 Do not drive with an extremely low fuel
level.
 If at any time you suspect that
exhaust fumes are entering the
vehicle, have the problem
checked and corrected as soon
as possible. If you must drive
under these conditions, drive
only with all windows fully open.Keep the trunk lid closed while
driving to prevent exhaust gas
from entering the vehicle.
WARNING
Avoid fire hazards. Do not drive
or park the vehicle anywhere near
flammable materi als (e.g. grass,
paper, rags or leaves), because
the catalytic converter operates
at very high temperatures. Keep everyone and flammable
materials away from the exhaust
pipe while the engine is running.
The exhaust gas is very hot.

Winter Driving
295
Driving Tips8
– CONTINUED –
When parking for long periods in cold
weather, you should observe the following
tips.
1. For MT models, place the shift lever in
the “1” or “R” position. For AT models,
place the select lever in the “P” position.
2. Use tire stops under the tires to
prevent the vehicle from moving.
▼
Refueling in cold weather
To help prevent moisture from forming in
the fuel system and t he 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 anti-
freeze 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
behavior can cause the wheels to lock,
possibly leading to loss of vehicle control.
An anti-lock brake system (ABS)
enhances your vehicle’s braking perfor-
mance on snowy and icy roads. For infor-
mation about braking on slippery
surfaces, refer to "ABS (Anti-Lock Brake
System)"
P245 and "Vehicle Stability
Control (VSC)/TRAC System" P247.
For AT models, use the Snow mode when
driving on snowy or icy roads. For details
about how to use the mode, refer to
"Driving Mode Select Switch (If
Equipped)"  P241.
▼
Wiper operation when snowing
Before driving in cold weather, make sure
the wiper blade rubbers are not frozen to
the windshield.
If the wiper blade rubbers are frozen to the
windshield, use the defroster with the
airflow selection in “ ” and the tempera-
ture set for maximum warmth until the
wiper blade rubbers are completely
thawed. Refer to "Cli mate Control Panel"
 P198.
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
Do not use the cruise control on
slippery roads such as snowy or icy
roads. This may cause loss of vehi-
cle control.
CAUTION
Avoid prolonged continuous driving
in snowstorms. Snow will enter the
engine’s intake system and may
hinder the airflow, which could
result in engine shutdown or even
breakdown.

Tires and Wheels
35811-21. Tires and Wheels■
Types of Tires
You should be familiar with type of tires
present on your vehicle.
▼
Summer tires
The factory-installed tires on your new
vehicle are summer tires.
Summer tires are high-speed capability
tires best suited for highway driving under
dry conditions.
Summer tires are inadequate for driving
on slippery roads such as on snow-
covered or icy roads.
If you drive your vehicle on snow-covered
or icy roads, we strongly recommend the
use of winter (snow) tires.
When installing winter tires, be sure to
replace all four tires.
▼A ll season tires
All season tires are designed to provide
an adequate measure of traction, handling
and braking performance in year-round
driving including snowy and icy road
conditions. However all season tires do
not offer as much traction performance as
winter (snow) tires in heavy or loose snow
or on icy roads. All season tires are identified by “ALL
SEASON” and/or “M+S” (Mud & Snow) on
the tire sidewall.
▼
Wi
nter (snow) tires
Winter tires are best suited for driving on
sn ow-covered and icy roads. However
winter tires do not perform as well as
summer tires and all season tires on roads
other than snow-covered and icy roads.
NOTEIf the tread wears down below 0.16 in.
(4mm) on snow tires the effectiveness
of snow tires is lost.
▼
Lo w profile tires
Generally, low profile tires will wear more
rapidly and tire grip performance will be
reduced on snowy and/or icy roads when
compared to standard tires. Be sure to
use snow tires or tire chains on snowy
and/or icy roads and drive carefully at a
speed appropriate for road and weather
conditions.
NOTELow profile tires may cause greater
damage than usual to the wheel when
receiving impact from the road sur-
face. Therefore pay attention to the fol-
lowing: 
Be sure to use proper tire inflation
pressure. If tires are under-inflated,
they may be damaged more severely.
 Avoid pot holes, uneven pavement,
curbs and other road hazards. Failure
to do so may lead to severe tire and
wheel damage.
■
Tire Pressure Monitoring
Syste m (TPMS) (If Equipped)
The tire pressure monitoring system
provides the driver with a warning
message by sending a signal from a
sensor that is installed in each wheel
when tire pressure is severely low. The
tire pressure monitoring system will acti-
vate only when the vehicle is driven. Also,
this system may not react immediately to
a sudden drop in tire pressure (for
example, a blow-out caused by running
over a sharp object).
If you adjust the tire pressures in a warm
garage and will then drive the vehicle in
cold outside air, the resulting drop in tire
pressures may cause the low tire pressure
warning light to illuminate. To avoid this
problem when adjusting the tire pressures
in a warm garage, inflate the tires to pres-
sures higher than those shown on the tire
inflation pressure label. Specifically,
inflate them by an extra 1 psi (6.9 kPa,
0.07 kgf/cm
2) for every difference of 10°F
