If a course-correcting brake application occurs,
t he red warning lamp Oashes in the outside mirror
and a warning tone sounds. In addition, a display
1 indicating the danger of a side collision
appears in the driver's display.
In rare cases, the system may make an inappro-
priate brake application. This brake application
may be interrupted at any time if you steer slightly
in the opposite direction or accelerate. System limits
Eit

her a course-correcting brake application
appropriate to the driving situation, or none at all,
may occur especially in the following situations:
= Vehicles or obstacles, e.g. crash barriers, are
located on both sides of your vehicle.
= A vehicle approaches too closely on the side.
= You have adopted a sporty driving style with
high cornering speeds.
= You brake or accelerate signiNcantly.
= A driving safety system intervenes, e.g. ESP n
or Active Brake Assist.
= ESP n
is deactivated.
= A loss of tyre pressure or a defective tyre is
detected.
= Transport equipment, for example a trailer or
bicycle rack, is attached to the trailer hitch
and the electrical connection has been cor-
rectly established. Activating/deactivating Active Blind Spot Assist

Function of Active Lane Keeping Assist
A

ctive Lane Keeping Assist monitors the area in
front of your vehicle by means of the multifunction
camera (  page 264) and can warn you before
you leave your lane unintentionally. The system
can guide you back into your lane through a
course-correcting steering intervention and addi-
tionally warns you with vibration pulses in the
steering wheel. Active Lane Keeping Assist is
available in the speed range between 60 km/h
and 200 km/h. 298
Driving and parking

The system can intervene in the following situa-
tions:
= A
ctive Lane Keeping Assist detects a lane
marking.
= One of your front wheels goes over a lane
marking.
If you activate the turn signal indicator, a steering
intervention does not occur on the corresponding
side.
If the system detects an obstacle, such as another
vehicle in the adjacent lane, a steering interven-
tion occurs regardless of the turn signal indicator.
If you leave the lane without activating the turn
signal indicator, but danger of a collision with a
moving obstacle is detected in your lane, a steer-
ing intervention does not occur. Display
1 will appear in t
he driver's display and a
warning tone will sound in the following situations:
= A steering intervention by Active Lane Keeping
Assist lasts longer than approximately ten sec-
onds.
= The system carries out two or more steering
interventions within approximately three
minutes without any steering intervention from
the driver.
In the Active Lane Keeping Assist settings, you
can set the sensitivity of the system and set the
level of support. Additionally, you can set whether
the system should react to discontinuous lane markings or only continuous lane markings
( pag

e 301).

is deactivated or a tire pressure
loss warning is displayed, Active Lane

ted.
ï Yellow: t
here is a malfunction. Please also
observe the display messages.
ð Grey: A
ctive Lane Keeping Assist is activa-
ted, but not operating.
ð Green: A

vated and operating. If the system is opera-
tional on only one side, the lane marking is
shown in green on the corresponding side.
ð Red: A
ctive Lane Keeping Assist has gui-
ded you back into your lane with a course-
correcting steering intervention. The status
display will Oash if there is also a haptic
warning in the steering wheel. The lane Driving and parking

ing assistance is activ
ated, the Active Lane
Keeping Assist warning is also accompanied
by ambient lighting (  page 180). System limits
In t

he following situations, a lane-correcting steer-
ing intervention may not occur but rather a warn-
ing may be given on the steering wheel, depend-
ing on the situation:
= You clearly and actively steer, brake or accel-
erate.
= If a driving safety system intervenes, such as
ESP n
, Active Brake Assist or Active Blind Spot
Assist.
= You have adopted a sporty driving style with
high cornering speeds or high rates of acceler-
ation.
= If transport equipment, forexample a trailer or
bicycle rack, is attached to the trailer hitch
and the electrical connection has been cor-
rectly established.
The system may be impaired or may not function
particularly in the following situations:
= If there is poor visibility, e.g. due to insuPcient
illumination of the road, highly variable shade
conditions, rain, snow, fog or heavy spray. =
If t here is glare, e.g. from oncoming traPc, the
sun or reOections.
= If there is dirt on the windscreen in the vicinity
of the multifunction camera or if the camera is
misted up, damaged or obscured.
= If there is dirt on the bumper in the area of the
radar sensors, or if they are damaged or cov-
ered.
= If there are no lane markings, or several
unclear lane markings are present for one
lane, e.g. around roadworks.
= If the lane markings are worn, dark or cov-
ered.
= If the distance to the vehicle in front is too
short and thus the lane markings cannot be
detected.
= If the lane markings change quickly, e.g. lanes
branch oM, cross one another or merge.
= If the carriageway is very narrow and winding.

responsibility; you may otherwise fail to recognise
dangers (  page 263). 300

Function of AIRMATIC
AIRMA

TIC is an air suspension system with varia-
ble damping for improved driving comfort. The all-
round level control system ensures the best possi-
ble suspension and constant ground clearance,
even with a laden vehicle. When driving at speed, the vehicle is lowered automatically to improve
dr
iving safety and to reduce fuel consumption.
You also have the option of manually adjusting the
vehicle level.
AIRMATIC includes the following components and
functions:
= Air suspension with automatic all-round level
control
= Speed-dependent lowering to reduce fuel con-
sumption
= Increased vehicle level for greater ground
clearance, selected via the multimedia system
= ADS PLUS (Adaptive Damping System with
constant damping force adjustment)

Function of ROAD SURFACE SCAN
% This function is not available in all countries.
The ROAD SURFACE SCAN function monitors the
r
oad in front of your vehicle using a multifunction
camera (  page 264). ROAD SURFACE SCAN detects unevenness in the road surface, e.g.
bum

ps, before the vehicle drives over them. Chas-
sis movements are reduced and driving comfort is
increased.
ROAD SURFACE SCAN is automatically activated
if the following conditions are met:
= Drive program  is not selected.
= No raised vehicle level is set.
= You are driving at a speed between 7 km/h
and 180 km/h.
System limits
ROAD SURFACE SCAN can be impaired in the fol-
lowing situations or can stop functioning:
= If the carriageway is insuPciently lit, e.g. at
night.
= In snow, rain, fog, heavy spray, if there is glare,
in direct sunlight or in greatly varying light
conditions.
= If the windscreen in the area of multifunction
camera is dirty, misted up, damaged or cov-
ered. 304
