Never run the engine in a closed space, such as a garage, ex-
cept for the brief time needed to drive the vehicle in or out of it. Avoid remaining in a parked vehicle for a lengthy time while
the engine is running. If that is unavoidable, then use the ventila-tion fan to force fresh air into the vehicle. Always keep the front ventilator inlet grille free from snow,
leaves or other obstructions to ensure that the ventilation system
always works properly. If at any time you suspect that exhaust fumes are entering the
vehicle, have the problem checked and corrected as soon as pos-
sible. If you must drive under these conditions, drive only with allwindows fully open. Keep the trunk lid or rear gate closed while driving to prevent
exhaust gas from entering the vehicle.
DRINKING AND DRIVING WARNING
Drinking and then driving is very dangerous. Alcohol in the
bloodstream delays your reaction and impairs your perception,judgment and attentiveness. If you drive after drinking – even if
you drink just a little – it will increase the risk of being involved in
a serious or fatal accident, injuring or killing yourself, your pas-sengers and others. In addition, if you are injured in the accident,
alcohol may increase the severity of that injury. Please don ’t drink and drive.
Drunken driving is one of the most frequent causes of accidents. Since
alcohol affects all people differently, you may have consumed too much
alcohol to drive safely even if the level of alcohol in your blood is belowthe legal limit. The safest thing you can do is never drink and drive. How-ever if you have no choice but to drive, stop drinking and sober up com-
pletely before getting behind the wheel.

TIRE PRESSURESWARNING
Driving at high speeds with excessively low tire pressures can
cause the tires to deform severely and to rapidly become hot. Asharp increase in temperature could cause tread separation, and
destruction of the tires. The resulting loss of vehicle controlcould lead to an accident.
Check and, if necessary, adjust the pressure of each tire (including the
spare) at least once a month and before any long journey.
Check the tire pressure when the tires are cold.
Use a pressure gauge to adjust the tire pressures to the values shown on
the tire placard.Refer to the “Tires and wheels ” section in chapter 11 for detailed
information.

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:

Brake system warning light
If any lights fail to come on, it indicates a burned-out bulb or a malfunc-
tion of the corresponding system.
Consult your authorized SUBARU dealer for repair. Seatbelt warning light and chime
When the ignition switch is turned to the “ON” position, the seatbelt
warning light will come on and the reminder chime will sound for about
six seconds to remind the driver to fasten the seatbelt.
The seatbelt warning light remains on for about six seconds and turns off
automatically after six seconds.
The seatbelt reminder chime will turn off when the driver ’s side seatbelt is
buckled or it will turn off automatically after six seconds. SRS airbag system warning light AIRBAG
When the ignition switch is turned to the “ON” position, the SRS airbag
system warning light will come on for about six seconds and go out. This
shows the SRS frontal airbag and SRS side airbag (if equipped) and
seatbelt pretensioners are in normal operation.
If this light comes on while driving or remains illuminated even after a
period of about 6 seconds from when the ignition has been turned on, it
may indicate that the SRS frontal airbag system or SRS side airbag sys-
tem (if equipped) or seatbelt pretensioner system is not working proper-
ly. Contact your nearest SUBARU dealer immediately.

CHECK ENGINE warning light/Malfunction indicator lamp
CAUTION
If the CHECK ENGINE light comes on while you are driving, have
your vehicle checked/repaired by your SUBARU dealer as soonas possible. Continued vehicle operation without having the
emission control system checked and repaired as necessarycould cause serious damage, which may not be covered by your
vehicle’ s warranty.
If this light comes on steadily or blinks while the engine is running, it may
indicate that there is a problem or potential problem somewhere in the
emission control system. If the light comes on steadily:
If the light comes on steadily while driving or does not go out after the
engine starts, an emission control system malfunction has been de-tected.
You should have your vehicle checked by an authorized SUBARU
dealer immediately. NOTE This light also comes on when the fuel filler cap is not tightened until it clicks.
If you have recently refueled your vehicle, the cause of the CHECK
ENGINE warning light/malfunction indicator lamp coming on could be a
loose or missing fuel filler cap. Remove the cap and retighten it until it
clicks. Make sure nothing is interfering with the sealing of the cap.
Tightening the cap will not make the CHECK ENGINE warning light
turn off immediately. It may take several driving trips. If the light does
not go out, take your vehicle to your authorized SUBARU dealer
immediately. If the light is blinking:
If the light is blinking while driving, an engine misfire condition has

been detected which may damage the emission control system.
To prevent serious damage to the emission control system, youshould do the following:Reduce vehicle speed.
Avoid hard acceleration.
Avoid steep uphill grades.
Reduce the amount of cargo, if possible.
Stop towing a trailer as soon as possible.
The CHECK ENGINE warning light may stop blinking and come on
steadily after several driving trips. You should have your vehicle
checked by an authorized SUBARU dealer immediately.
Charge warning light
If this light comes on when the engine is running, it may indicate that the
charging system is not working properly. If the light comes on while driving or does not go out after the engine
starts, stop the engine at the first safe opportunity and check the alterna-
tor belt. If the belt is loose, broken or if the belt is in good condition but
the light remains on, contact your nearest SUBARU dealer immediately. Oil pressure warning light
CAUTION
Do not operate the engine with the oil pressure warning light on. This may cause serious engine damage.
If this light comes on when the engine is running, it may indicate that the
engine oil pressure is low and the lubricating system is not working prop-
erly.If the light comes on while driving or does not go out after the engine
starts, stop the engine at the first safe opportunity and check the engine
oil level. If the oil level is low, add oil immediately. If the engine oil is at
the proper level but the light remains on, contact your nearest SUBARU
dealer immediately.

The warning light comes on right after the engine is started but
goes out immediately, remaining off. The warning light remains on after the engine has been started,
but it goes out when the vehicle speed reaches about 8 mph (12km/h). The warning light comes on during driving, but it goes out
immediately and remains off.
When driving with an insufficient battery voltage such as when the en-
gine is jump started, the ABS warning light may come on. This is due to
the low battery voltage and does not indicate a malfunction. When the
battery becomes fully charged, the light will go out. VDC (Vehicle Dynamics Control) warning light (if equipped)
This warning light comes on when the ignition switch is turned to the
“ON” position and goes out after the engine has started. It indicates that
the VDC system is operational.
The VDC system is probably inoperative under any of the following
conditions. Immediately have your vehicle checked at a SUBARU dealer. The VDC warning light does not come on when the ignition switch is
turned to the “ON” position.
The VDC warning light remains on after the engine has started and
stays lit even when the vehicle speed reaches about 8 mph (12 km/h). The VDC warning light comes on while the vehicle is running.
If the electrical circuit of the VDC system itself becomes faulty, the
VDC warning light only comes on. At this time, the ABS (Anti-lock Brake
System) remains fully operational. The warning light comes on when the electronic control system of the
ABS/VDC system becomes faulty.
The VDC system provides its ABS control through the electrical circuit of
the ABS system. Accordingly, if the ABS is inoperative, the VDC system
also becomes unable to provide ABS control. As a result, the VDC sys-
tem becomes inoperative, causing the VDC warning light to come on.
Though both the VDC and ABS systems are inoperative in this case, the
ordinary functions of the brake system are still available. You will be safe

while driving with this condition, but you should have your vehicle checked at a SUBARU dealer as soon as possible. NOTE
If the warning light behavior is as shown below, the VDC system may be considered normal.The warning light comes on right after the engine is started but
goes out immediately, remaining off. The warning light remains on after the engine has been started,
but it goes out when the vehicle speed reaches 8 mph about (12km/h). The warning light comes on during driving, but it goes out im-
mediately and remains off. Brake system warning light
WARNING
Driving with the brake system warning light on is dangerous.
This indicates your brake system may not be working properly. If the light remains on, have the brakes inspected by a SUBARU
dealer immediately. If at all in doubt about whether the brakes are operating prop-
erly, do not drive the vehicle. Have your vehicle towed to the
nearest SUBARU dealer for repair.
This light has the following two functions: Parking brake warning
The light comes on with the parking brake applied while the ignition switch is in the “ON” position. It goes out when the parking brake is
fully released. Brake fluid level warning
This light comes on when the brake fluid level has dropped to near the “MIN” level of the brake fluid reservoir with the ignition switch in
the “ON” position and with the parking brake fully released.

VDC (Vehicle Dynamics Control) OFF indicator light (if equipped)
This indicator light comes on when the ignition switch is turned ON
and goes out about 6 seconds after the engine has started. It comes on when the VDC system is deactivated (by operating “VDC
OFF” switch or in the standby state).
NOTE The light may stay on for a while after the engine has been
started, especially in cold weather. This does not indicate the exis- tence of a problem. The light should go out as soon as the enginehas warmed up. The “VDC OFF ” indicator light comes on when the engine has de-
veloped a problem and the CHECK ENGINE warning light is on.
The VDC system is probably faulty under any of the following conditions. Have your vehicle checked at a SUBARU dealer as soon as possible. The VDC OFF indicator light does not come on when the ignition
switch is turned to the “ON” position.
The light does not go out even after several minutes have passed (the
engine has warmed up) after the engine has been started. Security system status indicator light (if equipped)
This light is found at the bottom center of the combination meter panel. On vehicles equipped with a security system, it blinks to show the driver
the operational status of the security system. For detailed information, re-fer to the “Security system ” in Chapter 2.
Shift position indicator (for AT vehicles)
This indicator shows the position of the shift lever. Turn signal indicator lights
These lights show the operation of the turn signal or lane change signal.
If the indicator lights do not blink or blink rapidly, the turn signal bulb
may be burned out. Replace the bulb as soon as possible. Refer to the
