Temperature gauge
CAUTION
If the pointer exceeds the normal operating range, safely stop the
vehicle as soon as possible.
See “ In case of emergency ” in chapter 9.
HB2012BB
The temperature gauge shows engine coolant temperature when the
ignition switch is in the “ON” position.
The coolant temperature will vary in accordance with the outside temper-
ature and driving conditions.
We recommend that you drive moderately until the pointer of the temper-
ature gauge reaches near the middle of the range. Engine operation is
optimum with the engine coolant at this temperature range and high rev-
ving operation when the engine is not warmed up enough should beavoided.
Warning and indicator lights
Several of the warning and indicator lights come on momentarily and
then go out when the ignition switch is initially turned to the “ON” posi-
tion. This permits checking the operation of the bulbs.
Apply the parking brake and turn the ignition switch to the “ON” position.
The following lights come on:

4-12Automatic 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.
The automatic climate control system automatically controls outlet air
temperature, fan speed, air flow distribution air-inlet control, and air con-
ditioner compressor operation. It activates when the “AUTO” switch is
pressed, and is used in conjunction with the Temperature control dial to
maintain a constant, comfortable climate within the passenger compart-ment.
The temperature can be set within a range of 65 – 85 F (18 – 32 C).
NOTE
The temperature is shown in units of Fahrenheit for US model and in Centigrade for Canadian model.

Engine 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 engine overheats, safely pull off the road and stop the vehicle in asafe place. If steam is coming from the engine compartment
Turn the engine off and get everyone away from the vehicle until itcools down. If no steam is coming from the engine compartment
1. Keep the engine running at idling speed.
2. Open the hood to ventilate the engine compartment.
Confirm that the cooling fan is turning. If the fan is not turning, im-
mediately turn the engine off and contact your authorized dealer for
repair.
3. After the engine coolant temperature has dropped, turn off the en-gine.
If the temperature gauge stays at the overheated zone, turn the en-
gine off.
4. After the engine has fully cooled down, check the coolant level in
the reserve tank.If the coolant level is below the “MIN” mark, add coolant up to the
“MAX” mark.
5. If there is no coolant in the reserve tank, add coolant to the reserve
tank. Then remove the radiator cap and fill the radiator with coolant.
If you remove the radiator cap from a hot radiator, first wrap a thick
cloth around the radiator cap, then turn the cap counterclockwise
slowly without pressing down until it stops. Release the pressure from

Recommended grade and viscosity under severe driving conditions
If the vehicle is used in desert areas, in areas with very high tempera-
tures, or used for heavy-duty applications such as towing a trailer, use
of oil with the following grade and viscosities is recommended.
API classification SL (or SJ): SAE viscosity No.: 30, 40, 10W-50,
20W-40, 20W-50
Cooling 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.

controlled to operate when the engine coolant reaches a specific tem-
perature.If the radiator cooling fan does not operate even when the engine
coolant temperature gauge exceeds the normal operating range, the
cooling fan circuit may be defective. Check the fuse and replace it if
necessary. If the fuse is not blown, have the cooling system checked
by your SUBARU dealer.
If frequent addition of coolant is necessary, there may be a leak in the
engine cooling system. It is recommended that the cooling systemand connections be checked for leaks, damage, or looseness.
Engine coolant Checking the coolant level
Check the coolant level at each fuel stop.
HBB004FB
1. Check the coolant level on the outside of the reservoir while the
engine is cool.
2. If the level is close to or lower than the “LOW” level mark, add
coolant up to the “FULL” level mark. If the reserve tank is empty, re-
move the radiator cap and refill as required.

tighten it to the specified torque.
Aluminum wheels (if equipped)
Aluminum wheels can be scratched and damaged easily. Handle them
carefully to maintain their appearance, performance, and safety.
When any of the wheels is removed and replaced for tire rotation or to
change a flat, always check the tightness of the wheel nuts after driving
approximatly 600 miles (1,000 km). If any nut is loose, tighten it to the
specified torque. Never apply oil to the threaded parts, wheel nuts, or tapered surface
of the wheel. Never let the wheel rub against sharp protrusions or curbs.
Be sure to fit tire chains on uniformly and completely around the tire,
otherwise the chains may scratch the wheel. When wheel nuts, balance weights, or the center cap is replaced, be
sure to replace them with genuine SUBARU parts designed for aluminumwheels.
Windshield washer fluid
CAUTION
Never use engine coolant as washer fluid because it could cause paint damage.
Check the level of the washer fluid at each fuel stop. If the level is low, fill
the fluid up to the neck of the reservoir.Use windshield washer fluid. If windshield washer fluid is unavailable use
clean water.
In areas where water freezes in winter, use an anti-freeze type windshield
washer fluid. SUBARU Windshield Washer Fluid contains 58.5% methyl
alcohol and 41.5% surfactant, by volume. Its freezing temperature varies
according to how much it is diluted, as indicated below.
