04 Comfort and driving pleasure
Collision warning with Auto-brake*
support is activated. Brake support prepares
the brake system to react quickly, and the
brakes are applied slightly. This may be expe-
rienced as a light tug.
If the brakes are applied quickly, full braking
effect will be provided, even if pressure on the
brake pedal is light.
Auto-brake
If a collision is imminent and the driver has not
applied the brakes, the auto-brake function is
04
activated without the driver pressing the brake
pedal. Limited brake force is applied to reduce
the vehicle's speed when the collision occurs.
WARNING
The auto-brake function cannot prevent a
collision but instead is intended to reduce
speed at the moment of impact. For full
braking effect, driver must apply the brakes.
NOTE
The auto-brake function is always on and
cannot be turned off.
Operation
Some settings are controlled from the center
console via a menu system. For information on
how the menu system is used, see page 120.
