If this lig ht c omes on when the eng ine is running , it may ind ic ate that the
c harg ing system is not working p rop erly.
If the lig ht c omes on while d riving or d oes not g o out after the eng ine

This lig ht has the following two func tions:
Parking brake warning
The lig ht c omes on with the p arking b rake ap p lied w hile the ig nition
switc h is in the “ON ” p osition. It g oes out when the p arking b rake is
fully released . Brake fluid level warning
This lig ht c omes on when the b rake fluid level d rop s to near the “MIN ”
level of the b rake fluid reservoir with the ig nitio n switc h in the “ON ”
p osition and with the p arking b rake fully released .
If the b rake system warning lig ht should c ome on wh ile d riving with
the p arking b rake lever fully released , it c ould b e an ind ic ation of
leaking of b rake fluid or worn b rake p ad s. In suc h a c ase, have your
vehic le c hec ked b y a SUBARU d ealer immed iately.
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 lig ht c omes on stead ily or b links while the eng ine is running , it may
ind ic ate that there is a p rob lem or p otential p rob l em somewhere in the
emission c ontrol system.
If the light comes on steadily:
If the lig ht c omes on stead ily while d riving or d oe s not g o out after the
eng ine starts, an emission c ontrol system malfunc ti on has b een d e-
tec ted .

d ealer immed iately.

3-8NOTE 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 indicatorlamp 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 lig ht is b linking while d riving , an eng ine m isfire c ond ition has

To p revent serious d amag e to the emission c ontrol s ystem, you
should d o the following : Red uc e vehic le sp eed .
Avoid hard ac c eleration.
Avoid steep up hill g rad es.
Red uc e the amount of c arg o, if p ossib le.
Stop towing a trailer as soon as p ossib le.
The CHECK ENGINE warning lig ht may stop b linking an d c ome on

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 d riving with an insuffic ient b attery voltag e s uc h as when the en-

Do not place any foreign objects, especially metal ones such
as coins or aluminum foil, into the accessory power socket. That could cause a short circuit. Always put the cap on the accessorypower socket when it is not in use. Use only electrical appliances which are designed for 12V DC
and which consume less than 120W. Overloading the accessorypower socket can cause a short circuit. Do not use double adapt-ers or more than one electrical appliance. If the plug on your electric appliance is either too loose or too
tight for the accessory power socket, this can result in a poorcontact or cause the plug to get stuck. Only use plugs that fitproperly in the accessory power socket. Use of an electric appliance in the accessory power socket for
a long period of time while the engine is not running can causebattery discharge.
