Hill Start Assist - Mercedes-Benz GLK-Class Service Manual

Hill Start Assist

The Hill Start Assist function prevents the vehicle from
rolling backwards immediately when starting off on an
uphill slope. This system maintains the required brake
pressure for a short period of time after the brake
pedal is released. This allows the driver to comfortably
move his / her foot from the brake pedal to the accel-
erator pedal without the vehicle rolling back straight
away. The system detects an uphill slope automati-
cally and activates the Hill Start Assist function.
The Hill Start Assist function is immediately aborted if:
• The driver actuates the parking brake
• The engine is shut off
• The transmission is shifted to neutral
• The driver aborts the start-off procedure by
releasing the accelerator pedal
• The transmission is shifted from a forward gear to
a reverse gear
