WARNING

Warnings and brake interventions can be
triggered late or not at all if the traffic sit-
uation or external influences prevent the
camera and radar unit from properly
detecting pedestrians, cyclists, large ani-
mals or vehicles ahead of the vehicle.
To be able to detect vehicles at night, its
front and rear lights must work and illumi-
nate clearly.
The camera and radar unit have a limited
range for pedestrians and cyclists – the
system can provide effective warnings
and brake interventions if the relative
speed is lower than 50 km/h (30 mph).
For stationary or slow-moving vehicles,
warnings and brake interventions are
effective at vehicle speeds of up to
70 km/h (43 mph). Speed reduction for
large animals is less than 15 km/h
(9 mph) and can be achieved at vehicle
speeds over 70 km/h (43 mph). At lower
speeds, the warning and brake interven-
tion for large animals is less effective.
Warnings for stationary or slow-moving
vehicles and large animals can be disen-
gaged due to darkness or poor visibility.
Warnings and brake interventions for
pedestrians and cyclists are disengaged
at vehicle speeds over 80 km/h
(50 mph).
Do not place, affix or mount anything on
the inside or outside of the windshield, or
in front of or around the camera and
radar unit – this could disrupt camera-
based functions.
Objects, snow, ice or dirt in the area of
the camera sensor can reduce the func-
tion, disengage it completely or give an
improper function response.
NOTE The function uses the vehicle's combined
camera and radar unit, which has certain gen-
eral limitations; see sections "Camera limita-
tions" and "Radar sensor limitations".
Market limitationsCity Safety is not available in all countries. If City

BLIS*
The BLIS 74
function is designed to help provide
assistance in heavy traffic with several lanes
moving in the same direction by helping the
driver to detect the presence of vehicles in the
"blind spot" area behind and to the side of the
vehicle.
BLIS is a driver support system designed to alert
the driver of:
vehicles in your "blind spot"
vehicles approaching rapidly in adjacent
lanes. Location of BLIS indicator light.

Blind spot zone
Rapidly approaching vehicle zone.
The BLIS function is active at speeds
above 10 km/h (6 mph).
The system is designed to react to: vehicles passing your vehicle
vehicles that are rapidly approaching your
vehicle from behind.
When BLIS

detects a vehicle in zone 1 or a rap-
idly approaching vehicle in zone 2, an indicator
light will illuminate in the relevant rearview mirror
and glow steadily. If the driver then uses the turn
signal on the side in which the warning has been 74

given, the indicator light will become brighter and
begin flashing.
NOTE
The light illuminates on the side of the vehicle
where the system has detected the vehicle. If
the vehicle is passed on both sides simulta-
neously, both lights come on.
WARNING

The BLIS function is supplementary driver
support intended to facilitate driving and
help make it safer – it cannot handle all
situations in all traffic, weather and road
conditions.
The responsibility for changing lanes
safely and using good judgment always
rests with the driver.
BLIS is not a substitute for the driver's
attention and judgment. The driver is
always responsible for ensuring the vehi-
cle is driven in a safe manner, at the
appropriate speed, with an appropriate
distance to other vehicles, and in accord-
ance with current traffic rules and regula-
tions.

Driver Alert Control (p. 370) Driver Alert Control limitations
Driver Alert Control (DAC) functionality may be
reduced in certain situations.
In certain situations, the system may provide a
warning even if it has not detected a change in
driving behavior, e.g.:
in strong crosswinds
on grooved road surfaces.
WARNING In certain cases, driving behavior might not be
affected despite the driver's fatigue – when
using the Pilot Assist function – resulting in
the driver not getting a warning from DAC.
It is therefore very important to always stop
and take a break at the slightest sign of fati-
gue, regardless of whether the DAC function
has issued a warning or not.
NOTE
The function uses the vehicle's camera unit,
which has some general limitations – see the
section "Camera unit limitations".

Lane Keeping Aid (LKA 104
) is designed to
actively steer the vehicle on freeways, highways
and other major roads to help the driver reduce
the risk of the vehicle unintentionally veering out
of the lane.
Lake Keeping Assistance steers the vehicle back
into the lane and/or alerts the driver using vibra-
tions in the steering wheel.
Lane Keeping Aid is active at speeds between
65-200 km/h (40-125 mph) on roads with
clearly visible traffic lane marker lines.
On narrow roads, the function may be unavailable
and go into standby mode. The function will
become available again when the road becomes
sufficiently wide. A camera monitors the road/traffic lane's marker lines.
