Auto-Hold Brake Function; Brake Assist System - Volvo XC90 Owner's Manual

Auto-hold brake function

With the Auto-hold brake function, the driver can
release the brake pedal and the brakes will
remain applied, for example, when the vehicle
has stopped at a traffic light or intersection.
When the vehicle is no longer moving forward,
Auto-hold applies the brakes automatically, either
using the normal brakes or the parking brake.
The brakes will be released when the accelerator
pedal is depressed.
If the driver's door is opened or the engine is
turned off, the parking brake will be applied auto-
matically.
Auto-hold is deactivated when the transmission is
in neutral or if the driver's door is open and the
seat belt is unbuckled.

ing backwards when starting up a hill.

STARTING AND DRIVING

Brake assist system

The Brake Assist System (BAS) increases brak-
ing force, thereby helping reduce braking dis-
tance.
The system monitors the driver's braking habits
and increases braking force when necessary.
Brake force can be increased up to the point at
which the ABS system is activated. The function
is deactivated when pressure on the brake pedal
decreases.
