Subaru Legacy BN/BS (2015-2019) Owners Manual: Hill start assist system (MT models)

The Hill start assist system is a device to make the following vehicle operations easier.

1) Starting forward facing uphill
2) Starting backward facing downhill

In both these cases, when the clutch pedal is depressed while the brake pedal is also depressed, braking power is maintained temporarily by the Hill start assist system when the brake pedal is released. The driver is therefore able to start the vehicle the same way as on a level grade, just using the clutch and accelerator pedal.

If the braking power of the Hill start assist system is insufficient after the brake pedal is released, apply more braking power by depressing the brake pedal again.

The Hill start assist system may not operate on slight grades. Also, the Hill start assist system does not operate in the following cases.

• when starting backward facing uphill
•  when starting forward facing downhill
•  while the parking brake is applied
•  while the ignition switch is in the "ACC" or "LOCK"/"OFF" position
•  while the Hill Holder indicator light is

OFF

When using the Hill start assist system, a braking effect may be felt even after the brake pedal has been released. However, this braking effect should disappear once the clutch pedal is released.

NOTE A slight jolt may be felt when the vehicle begins to move forward after being reversed.

To activate/deactivate the Hill start assist system

When activating/deactivation the Hill Holder function, the Hill start assist system will also be activated/deactivated. For details about activating/deactivating the Hill Holder function, refer to "Hill Holder switch" .
