Subaru Crosstrek Owners Manual: Hill start assist system

WARNING

• The Hill start assist system is a device only for helping the driver to START the vehicle on an uphill grade. To prevent accidents when the vehicle is parked on a slope, be sure to firmly set the parking brake. When setting the parking brake, make sure that the vehicle remains stationary when the clutch pedal (MT models) and brake pedal (both MT and CVT models) are released.
• Do not turn the ignition switch to the "LOCK"/"OFF" position while the Hill start assist system is operating. The Hill start assist system will be deactivated and may lead to an accident.

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

1. Brake pedal (both MT models and CVT models)
2. Clutch pedal (MT models only)

In both these cases, the Hill start assist system operates under the following conditions.

• when the clutch pedal is depressed while the brake pedal is also depressed (MT models)
• when the vehicle has stopped with the brake pedal depressed (CVT models)

Braking power is maintained temporarily (for approximately 2 seconds) by the Hill start assist system after the brake pedal is released. The driver is therefore able to start the vehicle in the same way as on a level grade, just using the clutch pedal (MT models only) and accelerator pedal (all models).

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 start assist warning light/ Hill start assist OFF indicator light is illuminated

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

CAUTION

The braking power of the Hill start assist system may not be sufficient when strong braking power is needed (e.g., while towing a trailer).

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

CAUTION

While the Hill start assist system is deactivated, when starting on an uphill grade, braking power is not maintained if the brake pedal is released. Start on an uphill grade by using the parking brake.

You can activate/deactivate the Hill start assist system according to the following procedure.
