Brake Support
If the risk of collision continues to increase after
the collision warning has been given, 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 or begun to steer around the
vehicle, 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. The
driver must apply the brakes for full braking
effect.
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.
On and off
To switch Collision Warning on or off, go into
the menu
Car settings Collision
warning settings and select On or Off. When

Warning setting that was being used when it
was switched off will be the default setting.
Activating/deactivating warning signals
The collision warning system’s audible and vis-
ual signals are activated automatically when

Warning distance
The warning distance determines the level of
sensitivity used by the system. The warning
distance
Long provides an earlier warning.
Begin by using Long and if the system gives
too many warnings, try changing to Normal .
WARNING
•
The setting
Short
should only be used
in situations where traffic is light and
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 171.
