2005 Subaru Legacy Owner's Manual - Page 191

Instruments and controls We recommend that you drive moderately until the pointer of the temperature gauge reaches near the middle of the range. Engine 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. 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" position. 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: : Seatbelt warning light (The seatbelt warning light goes out only when you fasten the seatbelt.) : SRS airbag system warning light : CHECK ENGINE warning light / Malfunction indicator lamp : Charge warning light : Oil pressure warning light : AT OIL temperature warning light (AT vehicles) / : ABS warning light If the pointer exceeds the normal operating range, safely stop the vehicle as soon as possible. See the "In case of emergency" in chapter 9. 3-20
