Collision Warning System* - Limitations - Volvo V40 Cross Country Owner's Manual

NOTE
Even if the warning distance has been set
Long
to warnings could be perceived as
being late in certain situations, e.g. when
there are large differences in speed or if
vehicles in front brake heavily.
WARNING
No automatic system can guarantee
100 % correct function in all situations.
Therefore, never test Collision Warning
with Auto Brake by driving at people or
vehicles - this may cause severe damage
and injury and risk lives.
Checking settings
The settings required can be controlled on
the centre console display screen.

Collision warning system* - limitations

The function has certain limitations - for
example, it is not active until approx. 4 km/h.
The collision warning system's visual warning
signal may be difficult to notice in the event of
strong sunlight, reflections, when sunglasses
are being worn or if the driver is not looking
straight ahead. The warning sound should
therefore always be activated.
On slippery road surfaces the braking dis-
tance is extended, which may reduce the
capacity to avoid a collision. In such situa-
26 . tions the ABS and ESC (p. 184) systems will
provide best possible braking force with
maintained stability.
The visual warning signal can be temporar-
ily disengaged in the event of high passen-
ger compartment temperature caused by
strong sunlight for example. If this occurs
then the warning sound is activated even if
it is deactivated in the menu system.

ments are large, e.g. a very active driv-
ing style.
