Automatic climate control system (if equipped) NOTE Operate the automatic climate control system when the engine is
running. When the engine coolant is cold, for instance in cold weather, the
air flows through the windshield defroster outlets and the blowerruns at the lowest speed to prevent cold air from blowing directly
against the driver and front passenger. In the “AUTO” mode, if the air temperature in the passenger
compartment is cooled down to the specified temperature, the air
conditioner compressor stops automatically. For efficient defogging
or dehumidifying in cold weather, press the “A/C” switch on.
Even when cooling is not necessary, setting the temperature
much lower than the current outlet air temperature turns on the airconditioner compressor automatically and the “A/C” indicator light
on the control panel comes on.

Starting the engine
CAUTION
Do not operate the starter motor continuously for more than ten
seconds. If the engine fails to start after operating the starter forfive to ten seconds, wait for ten seconds or more before tryingagain.
Starting the engine for a manual transmission vehicle
1. Ap p ly the p arking b rake.
2. Turn off unnec essary lig hts and ac c essories.

9-14Engine overheating
WARNING
Never attempt to remove the radiator cap until the engine has been shut off and has fully cooled down. When the engine is hot,the coolant is under pressure. Removing the cap while the engineis still hot could release a spray of boiling hot coolant, which
could burn you very seriously.
If the eng ine overheats, safely p ull off the road a nd stop the vehic le in a
safe p lac e.
If steam is coming from the engine compartment
Turn the eng ine off and g et everyone away from the vehic le until it
c ools d own. If no steam is coming from the engine compartment
1. Keep the eng ine running at id ling sp eed .
2. Op en the hood to ventilate the eng ine c omp artment .
Confirm that the c ooling fan is turning . If the fan is not turning , im-
med iately turn the eng ine off and c ontac t your auth orized d ealer for
rep air.
3. After the eng ine c oolant temp erature has d rop p ed , turn off the en-
g ine.
If the temp erature g aug e stays at the overheated zo ne, turn the en-
g ine off.
4. After the eng ine has fully c ooled d own, c hec k the c oolant level in
the reserve tank.
If the c oolant level is b elow the “MIN ” mark, ad d c oolant up to the
“ MAX ” mark.
5. If there is no c oolant in the reserve tank, ad d c oolant to the reserve
tank. Then remove the rad iator c ap and fill the rad iator with c oolant.
If you remove the rad iator c ap from a hot rad iator, first wrap a thic k
c loth around the rad iator c ap , then turn the c ap c o unterc loc kwise
slowly without p ressing d own until it stop s. Releas e the p ressure from

11-4
Always use the proper tools and make certain that they are
well maintained. Never get under the vehicle supported only by a jack. Always
use a safety stands to support the vehicle. Never keep the engine running in a poorly ventilated area,
such as a garage or other closed areas. Do not smoke or allow open flames around the fuel or battery.
This will cause a fire. Because the fuel system is under pressure, replacement of the
fuel filter should be performed only by your SUBARU dealer. Wear adequate eye protection to guard against getting oil or
fluids in your eyes. If something does get in your eyes, thorough-
ly wash it out with clean water. Do not tamper with the wiring of the SRS airbag system or
seatbelt pretensioner system, or attempt to take its connectorsapart, as that may activate the system or it can render it inopera-tive. The wiring and connectors of these systems are yellow for
easy identification. NEVER use a circuit tester for these wiring. If your SRS airbag or seatbelt pretensioner needs service, con-
sult your nearest SUBARU dealer. Before checking or servicing in the engine compart- ment
Always stop the engine and set the parking brake firmly to pre-
vent the vehicle from moving. Always let the engine cool down. Engine parts become very
hot when the engine is running and remain hot for some time af-ter the engine is stopped. Do not spill engine oil, engine coolant, brake fluid or any other
fluid on hot engine components. This may cause a fire. Always remove the key from the ignition switch. When the
ignition switch is in the “ON” position, the cooling fan may oper-
ate suddenly even when the engine is stopped.

11-14Cooling system
WARNING
Never attempt to remove the radiator cap until the engine has
been shut off and has cooled down completely. Since the coolantis under pressure, you may suffer serious burns from a spray ofboiling hot coolant when the cap is removed.
CAUTION
The cooling system has been filled at the factory with a high
quality, corrosion-inhibiting, year-around coolant which providesprotection against freezing down to –33F ( –36 C). For adding,
use genuine SUBARU coolant or an equivalent: a mixture of 50%
soft water and 50% ethylene-glycol basis coolant. Use of improp-er coolants may result in corrosion in the cooling system. It is im-portant to maintain protection against freezing and corrosion,
even if freezing temperatures are not expected. Never mix differ-ent kinds of coolant. Do not splash the engine coolant over painted parts. The alco-
hol contained in the engine coolant may damage the paint sur-face.
Hose and connections
Your vehic le emp loys an elec tric c ooling fan whic h is thermostatic ally
c ontrolled to op erate when the eng ine c oolant reac h es a sp ec ific tem-

c ooling fan c irc uit may b e d efec tive. Chec k the fus e and rep lac e it if
nec essary. If the fuse is not b lown, have the c ooli ng system c hec ked
b y your SUBARU d ealer.
If freq uent ad d ition of c oolant is nec essary, there may b e a leak in the
eng ine c ooling system. It is rec ommend ed that the c ooling system

Windshield washer fluid
CAUTION
Never use engine coolant as washer fluid because it could cause paint damage.
Chec k the level of the washer fluid at eac h fuel st op . If the level is low, fill
the fluid up to the nec k of the reservoir.
Use wind shield washer fluid . If wind shield washer f luid is unavailab le use
c lean water.
In areas where water freezes in winter, use an anti -freeze typ e wind shield
