06 Starting and driving

Blind Spot Information System - BLIS*

06

146

* Option/accessory, for more information, see Introduction.

IMPORTANT

The lenses are electrically heated to melt ice

or snow. If necessary, brush snow away

from the lenses.

When BLIS operates

The system operates when the car is driven at

a speed above 10 km/h.

Overtaking

The system is designed to react if you overtake

another vehicle at a speed of up to 10 km/h

faster than the other vehicle.

The system is designed to react if you are over-

taken by a vehicle travelling up to 70 km/h

faster than your vehicle.

WARNING

BLIS does not work in sharp bends.

BLIS does not work when the car is revers-

ing.

A wide trailer coupled to the car can conceal

other vehicles in adjacent lanes. It can pre-

vent the vehicle in the screened area from

being detected by BLIS.

Daylight and darkness

In daylight the system reacts to the shape of

the surrounding vehicles. The system is

designed to detect motor vehicles such as

cars, trucks, buses and motorcycles.

In darkness the system reacts to the head-

lamps of surrounding vehicles. Vehicles with

headlamps that are switched off are not

detected by the system. This means for exam-

ple that the system does not react to a trailer

without headlamps which is towed behind a

car or truck.

WARNING

The system does not react to bicycles or

mopeds.

The BLIS cameras can be disrupted by

intensive light or when driving in the dark

when there are no light sources (e.g. street

lighting or other vehicles). The system may

then interpret the lack of light as if the cam-

eras have been blocked.

In both cases a message is shown on the

display.

When driving in such conditions system

performance may be temporarily reduced

and a text message is shown, see

page 147.

If the message disappears automatically

then BLIS has returned to normal function-

ality.

The BLIS cameras have limitations similar to

the human eye, i.e. they "see" worse in

heavy snowfall or thick fog for example.
