2) 10W-30, 10W-40
Recommended grade and viscosity under severe driving conditions
If the vehicle is used in desert areas, in areas with
very high temperatures, or used for heavy-duty ap-
plications such as a towing a trailer, use of oil with
the following grade and viscosities is recom-mended.
API classification SJ or SH: SAE viscosity No.: 30, 40, 10W-50, 20W-40,

Cooling system
WARNING
Never attempt to remove the radiator cap until the engine has been shut off and has cooled
down completely. Since the coolant is underpressure, you may suffer serious burns from a
spray of boiling hot coolant when the cap isremoved.
CAUTION
The cooling system has been filled at the
factory with a high quality, corrosion-inhibit-
ing, year-around coolant which provides protection against freezing down to –33°F
(–36 °C). For adding, use genuine SUBARU
coolant or an equivalent: a mixture of 50%
soft water and 50% ethylene-glycol basis cool-
ant. Use of improper coolants may result in
corrosion in the cooling system. It is impor- tant to maintain protection against freezing and corrosion, even if freezing temperaturesare not expected. Never mix different kinds ofcoolant.

Abnormally low tire pressure (tread worn at
shoulders)
HGB024AA
Rolling resistance is high, so fuel consumption is
also higher.
Abnormally high tire pressure (tread worn in
center)
HGB025AA
Ride comfort is poor. Also, the tire magnifies the
effects of road-surface bumps and dips, possibly
resulting in vehicle damage.
If the tire placard shows tire pressures for the ve-
hicle when fully loaded and for the vehicle when
towing a trailer, adjust the tire pressures to the val-
ues that match current loading conditions.
WARNING
Driving at high speeds with excessively low tire pressures can cause the tires to deform
severely and to rapidly become hot. A sharp
