To prevent serious damage to the emission control system, you should 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.

AT OIL TEMPerature warning light
(for AT vehicles)
If this light comes on when the engine is running, it may indicate that the
automatic transmission fluid temperature is too hot.
If the light comes on while driving, it is unnecessary to stop the vehicle,
but avoid driving up steep grades or in stop and go traffic.
Automatic transmission control system warning
If the light flashes after the engine starts, it may indicate that the auto-
matic transmission control system is not working properly. Contact
your nearest SUBARU dealer for service immediately.
ABS warning light
The ABS warning light comes on when the ignition switch is turned to the
“ON” position and goes out after about two seconds.
This is an indication that the ABS system is working properly.
CAUTION
If the warning light behaves as follows, the ABS system may not
work properly.When the warning light is on, the ABS function shuts down; how-
ever, the conventional brake system continues to operate normal-
ly. The warning light does not come on when the ignition switch
is turned to the “ON” position.
The warning light comes on when the ignition switch is turned
to the “ON” position, but it does not go out even when the vehicle
speed exceeds approximately 8 mph (12 km/h). The warning light comes on during driving.
If these occur, have the ABS system repaired at the first available
opportunity by your SUBARU dealer.
NOTE
If the warning light behavior is as shown below, the ABS 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 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

3-16while 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.
If the brake system warning light should come on while driving (with
the parking brake fully released and with the ignition switch posi- (U.S.)

Always make sure this light is out before you start to drive. Low fuel warning light
The low fuel warning light comes on when the tank is nearly empty about 2.6 U.S. gal. (10.0 liters, or 2.2 Imp. gal.). It only operates when the igni-
tion switch is in the “ON” position.
NOTE This light does not go out unless the tank is replenished up to an internal fuel quantity of about 3.7 U.S. gal. (14 liters, 3.1 Imp. gal.). Front-wheel drive warning light (for AT vehicles except GT and vehicle with VDC)
This light comes on when All Wheel Drive is disengaged and the drive
mechanism is switched to Front Wheel Drive for maintenance or similarpurposes. VDC (Vehicle Dynamics Control) operation indicator light (if equipped)
This light comes on when the ignition switch is ON and goes out about 2
seconds later.
It blinks when the skid suppression function is activated. It illuminates
when only the traction control function is operating.
The VDC system is probably faulty under any of the following conditions.
Have your vehicle checked at a SUBARU dealer immediately. The light does not come on when the ignition switch is turned to the
“ON” position.
The light does not go out even after a period of about 2 seconds after

3-18the ignition switch has been turned to the
“ON” position.
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.
