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
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 connot 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 122.

moving at low speeds.
•
Collision Warning alerts the driver to the
risk of a collision but this function can-
not reduce the driver's reaction time.
•
For Collision Warning to be as effective
as possible, it is recommended that Dis-
tance Alert be set to 4 or 5, see
page 179.

vehicle ahead brakes suddenly, warn-
ings may be considered to be late, even
if the setting Long has been selected.
