Vehicle level Important safety notes
Your vehicle regulates its height automati-
cally. All-round self-levelling ensures the best
possible suspension and constant ground
clearance, even with a laden vehicle. When
you drive fast, the vehicle is lowered auto-
matically to improve driving safety and to
reduce fuel consumption.
The following vehicle levels are possible:
R
normal
R raised: the vehicle is raised by about 25 mm
when compared with the normal level.
R lowered: the vehicle is lowered by about
10 mm when compared with the normal
level.
The "Normal" and "Raised" vehicle levels can
be set manually.
The "Lowered” vehicle level is set automati-
cally:
R at speeds above 140 km/h
R if you have selected "Comfort tuning"
(Y page 168) and then lock the vehicle
within 60 seconds of the engine being
switched off
R if you have selected "Sports tuning"
(Y page 168) G
Risk of injury
If you have selected "Comfort tuning", the
vehicle will be lowered if you lock it within 60
seconds of the engine being switched off.
Make sure, therefore, that nobody is in the
vicinity of the wheel housing or under the
vehicle when you lock the vehicle. Otherwise,
limbs could become trapped.

Important safety notes G
Risk of accident
PARKTRONIC is only an aid and may not
detec tall obstacles. This system does not
relieve you of the need to pay attention.
You are always responsible for safety and
must continue to pay attention to your imme-
diate surroundings when parking and
manoeuvring. You could otherwise endanger
yourself and others. G
Risk of injury
Make sure that no persons or animals are in
the manoeuvring range. Otherwise, they
could be injured.
PARKTRONIC is an electronic parking aid with
ultrasonic sensors .Itindicates visually and
audibly the distance between your vehicle
and an object. PARKTRONIC is activated automatically when
you:
R

When parking, pay particular attention to
objects above or below the sensors, such
as flower pots or trailer drawbars. PARK-
TRONIC does not detect such objects when
they are in the immediate vicinity of the
vehicle. You could damage the vehicle or
the objects.
The sensors may not detect snow and
objects which absorb ultrasonic sources.
Ultrasonic sources, such as an automatic
car wash, a lorry's compressed-air brakes
or a pneumatic drill, could cause PARK-
TRONIC to malfunction.
PARKTRONIC may not function correctly on
uneven terrain.

R
the lane markings change quickly, e.g.
lanes branch off, cross one anothe ror
merge.
R the road is narrow and winding.
Lane Keeping Assist cannot detect road and
traffic conditions. It is not a substitute for
attentive driving. You are responsible for the
vehicle's speed, braking in good time, and
steering correctly. Always adapt yourd riving
style to suitt he prevailing road and weather
conditions. Always pay attention to traffic
conditions and your surroundings. Otherwise,
you may fail to recognise dangers in time,
cause an accident and injure yourself and oth-
ers.
A warning can be given when a front wheel
passes over a lane marking. It will warn you
by means of intermittent vibration in the
steering wheel for up to 1.5 seconds.
In order that you are warned only when nec-
essary and in good time if you cross the lane
marking, the system recognises certain con-
ditions and warns you accordingly.
The warning vibration occurs earlier if:
R you approach the outer lane marking on a
bend.
R the road has very wide lanes, e.g. a motor-
way.
R the system recognises solid lane markings.
The warning vibration occurs later if:
R the road has narrow lanes.
R you cut the corner on a bend.
No warning vibration occurs if:
R you clearly and actively steer, brake, or
accelerate.
R you cut the corner on a sharp bend.
R a driving safety system intervenes, such as
ABS, BAS or ESP ®

General notes The Active Driving Assistance package con-
sists of DISTRONIC PLUS (Y page 154), Active
Blind Spot Assist (Y page 186) and Active
Lane Keeping Assist (Y page 189).
Active Blind Spot Assist Important safety notes
Active Blind Spot Assist uses a radar sensor
system to monitor the side areas of your vehi-
cle. In addition, it uses the radar sensor sys-
tem to monitor the front area as well. Active
Blind Spot Assist provides assistance at
speeds higher than about 30 km/h. Awarn-
ing lamp in the exterior mirror calls your
attentio nto a vehicle or certain obstacles
detected in the area monitored. If you then
switch on the corresponding turn signal to
change lane, you will also receive an optical
and acoustic collision warning. If a risk of lat-
eral collision is detected, corrective braking
may help you avoid a collision. 186

G
Risk of accident
Active Blind Spot Assist is only an aid and may
detect vehicles/obstacles incorrectly or not
at all.
The system may be impaired or may not func-
tion if:
R there is poo rvisibility, e.g. due to snow,
rain, fog or spray.
R the rear and/or front sensors are dirty.
Active Blind Spot Assist may not detect nar-
row vehicles, such as motorcycles or bicycles,
or only detect the mtoo late. It cannot detect
vehicles which are overtaken at a small dis-
tance and then enter the blind spot area.
Active Blind Spot Assist cannot detect road
and traffic conditions. It is not a substitute for
attentive driving. You are responsible for the
vehicle's speed, braking in good time, and
steering correctly. Always adapt your driving
style to suit the prevailing road and weather
conditions. Always pay attention to traffic
conditions and your surroundings. Otherwise,
you may fail to recognise dangers in time,
cause an accident and injure yourself and oth-
ers.
The radar sensor system is automatically
deactivated near radio telescope facilities
(Y page 327).
For Active Blind Spot Assist to assist you
when driving, the radar sensor system must
be activated (Y page 210) and operational.
Monitoring range
Active Blind Spot Assist monitors the area up
to three metres behind your vehicle and
directly next to your vehicle as shown in the
diagram. For this purpose, Active Blind Spot
Assist uses sensors in the rear bumper. G
Risk of accident
Active Blind Spot Assist monitors certain
areas in the immediate vicinity of your vehicle.
Vehicles that approach and drive past at high
speeds are not detected. No visual nor audi-
ble warnings are emitted and the system does
not brake the vehicle to correct your course.
If the lanes are very wide, it may not be pos-
sible to monitor the complete width of the
neighbouring lane. For this reason, vehicles in
the next lane may not be detected, especially
if they are driving in a staggered formation.
This may be the case if vehicles are driving at
the edge of their lane that is furthest away
from your vehicle.
Always pay attention to traffic conditions and
your surroundings. Otherwise, you may fail to
recognise dangers in time, cause an accident
and injure yourself and others.
If the lanes are narrow, the system may be
unable to distinguish the neighbouring lane
from the one beyond it. For this reason, vehi-
cles in the farther lane may be indicated,
especially if the vehicles are driving in a stag-
gered formation in different lanes. In particu-
lar, this may be the case if the vehicles are
driving at the edge of their lane nearest your
vehicle. Due to the nature of the system,
warnings may be issued in error when driving Driving systems
