7-10 Starting and operating/Starting and stopping the engine (models without push-button start system) CAUTION . If the engine is stopped during driving, the catalyst may over- heat and burn. . When starting the engine, be sure to sit in the driver’s seat (except when using the remote engine start system). NOTE . Avoid rapid racing and rapid accel- eration immediately after the engine has started. . Until the engine is warmed up suffi- ciently, the engine speed is maintained high. The engine speed will gradually drop as the engine warms up. . On rare occasions, it may be difficult to start the engine depending on the fuel used and the driving condition (repeated short trips when the engine is not warmed up sufficiently). In such a case, it is recommended to switch to a different brand of fuel. . On rare occasions, transient knock- ing may be heard from the engine when the accelerator is operated rapidly such as a rapid start-up and a rapid accel- eration. This is not a malfunction. . The engine starts more easily when the headlights, air conditioner and rear window defogger are turned off. . Do not shift the select lever (CVT models) or shift lever (MT models) while the starter is cranking. ! MT models S07BD0101 1. Apply the parking brake. 2. Turn off unnecessary lights and acces- sories. 3. Depress the clutch pedal to the floor and shift the shift lever into neutral. Hold the clutch pedal to the floor while starting the engine. The starter motor will only operate when the clutch pedal is depressed fully to the floor. 4. Turn the ignition switch to the “ON” position and check the operation of the warning and indicator lights. Refer to “Warning and indicator” F3-13. 5. Turn the ignition switch to the “START” position without depressing the accelera- tor pedal. Release the key immediately after the engine has started. If the engine does not start, try the following procedure. (1) Turn the ignition switch to the “LOCK”/“OFF” position and wait for at least 10 seconds. After checking that the parking brake is firmly set, turn the ignition switch to the “START” position while depressing the accelerator pedal slightly (approximately a quarter of the full stroke). Release the accelerator pedal as soon as the engine starts. (2) If this fails to start the engine, turn the ignition switch back to the “LOCK”/ “OFF” position and wait for at least 10 seconds. Then fully depress the accel- erator pedal and turn the ignition switch to the “START” position. If the engine starts, quickly release the ac- celerator pedal. (3) If this fails to start the engine, turn the ignition switch again to the “LOCK”/ “OFF” position. After waiting for 10 seconds or longer, turn the ignition switch to the “START” position without depressing the accelerator pedal. (4) If the engine still fails to start, contact your nearest SUBARU dealer for assistance. 6. Confirm that all warning and indicator lights have turned off after the engine has started. The fuel injection system auto- matically lowers the idle speed as the engine warms up.
