Temperature gauge
1) Normal operating range
The temperature gauge shows engine
coolant temperature when the ignition
switch is in the “ON” position. The coolant temperature will vary in ac-
cordance with the ou
tside temperature
and driving conditions.
We recommend that you drive moderately
until the pointer of the temperature gauge
reaches near the middle of the range. En-
gine operation is optimum with the engine
coolant at this temperature range and high
revving operation when the engine is not
warmed up enough should be avoided.

Promptly put fuel in the tank when-
ever the low fuel warning light
comes on. Engine misfires as a re-
sult of an empty tank could cause
damage to the engine.

Air conditioner operation
T Cooling or dehumidifying
For cooling and dehumidification of the
passenger compartment, air flows through
the instrument panel outlets:
1. Set the air inlet selection button to the
OFF position.
2. Set the air flow control dial to the “ ” position.
3. Set the air conditioner button to the
“ON” position.
4. Set the temperature control dial to the
blue side.
5. Set the fan speed control dial at the de-
sired speed. T Defrosting or defogging
To direct warm air to the windshield and
front door windows:
1. Set the air outlet control dial to the “ ” position.
2. Set the temperature control dial to the
red side.
3. Set the fan speed control dial at the
highest speed.
NOTE
In a vehicle equipped with an air condi-
tioner, when the dial is placed in the
“ ” position or “ ” position the
air conditioner compressor automati-
cally operates to quickly defog the
windshield. However the indicator on
the air conditioner
button will not come
on. At the same time, the air inlet selec-
tion is automatically set to “outside
air” mode.
In this state, you cannot select “recir-
culation” mode by manually pressing
the air inlet selection button.
Also, you cannot stop the air condi-
tioner compressor by pressing the air
conditioner button. Automatic climate control
system (if equipped)
NOTE y
Operate the automatic climate con-
trol system when the engine is run-
ning. y The blower fan rotates at a low speed
when the engine coolant temperature
is low.
For efficient defogging or dehumidify-
ing in cold weather, press the “A/C”button. y Even when cooling is not necessary,
setting the temperature much lower
than the current outlet air temperatureturns on the air c onditioner compres-
sor automatically and the “A/C” indica-
tor light on the control panel comes on.
The automatic climate control system au-
tomatically controls outlet air temperature,
fan speed, air flow distribution air-inlet
control, and air conditioner compressor
operation. It activates when the “AUTO”
button is pressed, and is used to maintain
a constant, comfortabl e climate within the
passenger compartment.
The temperature can be set within a rangeof 65 to 85 °F (18 to 32 °C).
Continued operation in the ON posi-
tion may fog up the windows.
Switch to the OFF position as soon
as the outside dusty condition
clears.

7-12 Starting and operating
NOTE yWhen the engine coolant tempera-
ture is still low, your vehicle’s automat-
ic transmission will up-shift at higher
engine speeds than when the coolant
temperature is sufficiently high in or-
der to shorten the warm-up time and
improve driveability. The gearshift tim-
ing will automatically shift to the nor-
mal timing after the engine has warmed
up.y Immediately after ATF (automatic
transmission fluid) is replaced, you
may feel that the automatic transmis-
sion operation is somewhat unusual.
This results from invalidation of data
which the on-board computer has col-
lected and stored in memory to allow the transmission to shift at the most
appropriate times for the current con-
dition of your vehicle. Optimized shift-
ing will be restored as the vehicle con-
tinues to be driven for a while. „
Selector lever
: Shift possible with brake pedal de-pressed
: Shift possible with brake pedal not depressed
The selector lever has four positions, “P”,
“R”, “N”, “D” and also has manual gate for
using “SPORT” mode or manual mode. T P (Park)
This position is for parking the vehicle and
starting the engine. In this position, the transmission is me-
chanically locked to prevent the vehicle
from rolling freely.
When you park the vehicle, first set the
parking brake fully, then shift into the “P”
position. Do not hold
the vehicle with only
the transmission. To shift the selector lever from the “P” to
any other position, you should depress the
brake pedal fully then move the selector
lever. This prevents the vehicle from
lurching when it is started. T R (Reverse)
This position is for backing the vehicle.
To shift from the “N” to “R” position, stop
the vehicle completely then move the le-
ver to the “R” position. T N (Neutral)
This position is for restarting a stalled en-
gine.
In this position the wheels and transmis-
sion are not locked. In this position, the
transmission is neutral; the vehicle will roll
freely, even on the slightest incline unless
the parking brake or foot brake is on.
Avoid coasting with the transmission neu-
tral.
During coasting, there is no engine brak- ing effect.
y
Avoid shifting from one of the for-
ward driving positions into the
“R” position or vice versa until the
vehicle has completely stopped.
Such shifting may cause damage
to the transmission.
y When parking the vehicle, first se-
curely apply the parking brake
and then place the selector lever
in the “P” position. Avoid parking
for a long time with the selector le-
ver in any other position as doing
so could result in a dead battery.

sary, use 1st gear) in order to utilize the
engine braking effect and prevent over-
heating of your vehicle’s brakes. Do not
make sudden downshifts. yWhen driving uphill in hot weather, the
air conditioner may turn off automatically
to protect the engine from overheating. y When driving uphill in hot weather, pay
attention to the water temperature gauge
pointer (for all vehicles) and AT OIL TEMP
warning light (for AT vehicles) since the
engine and transmission are relatively
prone to overheating under these condi-
tions. If the water temperature gauge
pointer approaches the OVERHEAT zone
or the AT OIL TEMP warning light illumi-
nates, immediately switch off the air con-
ditioner and stop the vehicle at the nearest
safe place. Refer to the “Engine overheat-
ing” section in chapter 9, and “Warning
and indicator lights” section in chapter 3.
NOTE
With AT vehicles, the temperature of
engine coolant is less likely to rise to
the OVERHEAT zone in the “D” posi-
tion than in the manual mode position. y If your vehicle has an automatic trans-
mission, avoid using the accelerator pedal
to stay stationary on an uphill slope in-
stead of using the parking brake or foot
brake. That may cause the transmission fluid to overheat. T
Parking on a grade
Always block the wheels under both vehi-
cle and trailer when parking. Apply the
parking brake firmly. You should not park
on a hill or slope. But if parking on a hill or
slope cannot be avoided, you should take
the following steps:
1. Apply the brakes and hold the pedal
down.
2. Have someone place wheel blocks un-
der both the vehicle and trailer wheels.
3. When the wheel blocks are in place, re-
lease the regular brakes slowly until the
blocks absorb the load.
4. Apply the regular brakes and then ap-
ply the parking brake; slowly release the
regular brakes.
5. Shift into 1st or reverse gear (manual
transmission) or “P” (automatic transmis-
sion) and shut off the engine.

9-12 In case of emergency
5. Start the engine of the vehicle with the
booster battery and run it at moderate
speed. Then start the engine of the vehi-
cle that has the discharged battery.
6. When finished, carefully disconnect the
cables in exactly the reverse order.Engine overheating
If the engine overheats, pull off the road
safely and stop the vehicle in a safe place. „If steam is coming from the
engine compartment
Turn off the engine and get everyone
away from the vehicle until it cools 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, immediately turn off the engine and contact your authorized
dealer for repair.
3. After the engine coolant temperature
has dropped, turn off the engine.
If the temperature gauge stays at the
overheated zone, turn off the engine.
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 counter-
clockwise slowly without pressing down
until it stops. Release the pressure from
the radiator. After the pressure has been
fully released, remove the cap by pressing
down and turning it.
Never attempt to remove the radia-
tor 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 engine is still hot
could release a spray of boiling hot
coolant, which could burn you very
seriously.

SAE viscosity number and applicable
temperature
*: 5W-30 is preferred.
Engine oil viscosity (t hickness) affects fuel
economy. Oils of lower viscosity provide
better fuel economy. However, in hot
weather, oil of higher viscosity is required
to properly lubricate the engine. „ Recommended grade and
viscosity under severe driv-
ing conditions
If the vehicle is used in desert areas, in ar-
eas with very high temperatures, or used
for heavy-duty applications such as tow-
ing a trailer, use of oil with the following
grade and viscosities is recommended.

tor cap until the engine has been
shut off and has cooled down com-
pletely. Since the coolant is under
pressure, you may suffer serious
burns from a spray of boiling hot
coolant when the cap is removed. yThe cooling system has been
filled at the factory with a high
quality, corrosion-inhibiting, 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 ba-
sis coolant. Use of improper cool-
ants may result in corrosion in the
cooling system. It is important to
maintain protection against freez-
ing and corrosion, even if freezing
temperatures are not expected.
Never mix different kinds of cool-
ant.
