Introduction

If you are driving at a speed over
30 km/h:ify
ou depress the brake sharply,
BAS PLUS automatically raises the brake
pressure to a value adapted to the traffic sit-
uation.
If you are driving at a speed under
30 km/h:ify ou depress the brake, BAS PLUS
is activated. Braking will be carried out at the
last possible moment.
If BAS PLUS demands particularly high brak-
ing force, preventative passenger protection
measures (PRE-SAFE ®
) are activated simul-
taneously.
X Keep the brake pedal depressed until the
emergency braking situation is over.
ABS prevents the wheels from locking.
BAS PLUS is deactivated and the brakes func-
tion as usual, if:
R you release the brake pedal.
R there is no longer any danger of a rear-end
collision.
R no obstacle is detected in front of your
vehicle.
The radar sensor system is switched off auto-
matically in the vicinity of radio telescope
facilities in the following vehicles:
R vehicles with COMAND Online and naviga-
tion

WARNING
PRE-SAFE ®
Brake will initially brake yourv ehi-
cle by a partial application of the brakes if a
danger of collision is detected. There may be
a collision unless you also brake. Automatic
emergency braking cannot prevent a colli-
sion. There is a risk of an accident.
Always apply the brakes yourself and try to
take evasive action. G
WARNING
PRE-SAFE ®
Brake cannot always clearly iden-
tify objects and complex traffic conditions.
In these cases, PRE-SAFE ®
Brake may:
R give an unnecessary warning and then
brake the vehicle
R neither give a warning nor intervene
There is a risk of an accident.
Always pay particular attention to the traffic
situation and be ready to brake, especially if
PRE-SAFE ®
Brake warns you. Terminate the
intervention in a non-critical driving situation.
In particular, the detection of obstacles can
be impaired if there is:
R dirt on the sensors or anything else cover-
ing the sensors

Driving safety systemsSafety

Winter driving
Important safety notes G
WARNING
If you shift dow nonaslippery road surface in
an attempt to increase the engine's braking
effect, the drive wheels could lose their grip.
This increases the risk of skidding and having
an accident.
Do not shift down for additional engine brak-
ing on a slippery road surface. G
DANGER
If the exhaust pipe is blocked or adequate
ventilation is not possible, poisonous gases
such as carbon monoxide (CO) may enter the
vehicle. This is the case, e.g. if the vehicle
becomes trapped in snow. There is a risk of
fatal injury.
If you leave the engine or the auxiliary heating
running, make sure the exhaust pipe and area
around the vehicle are clear of snow. To
ensure an adequate supply of fresh air, open
a window on the side of the vehicle that is not
facing into the wind.
Have your vehicle winterproofed at a qualified
specialist workshop at the onset of winter.
Observe the notes in the "Winter operation"
section (Y page 342).
Driving with summer tyres Observe the notes in the "Winter operation"
section (Y page 342).
Slippery road surfaces G
WARNING
If you shift down on a slippery road surface in
an attempt to increase the engine's braking
effect, the drive wheels could lose their grip.
This increases the risk of skidding and having
an accident.
Do not shift down for additional engine brak-
ing on a slippery road surface. If the vehicle threatens to skid or cannot be
stopped when moving at low speed:
X
Vehicles with manual transmission:
shift to neutral.
X Vehicles with automatic transmission:
shift the transmission to position N.
X Try to bring the vehicle under control by
using corrective steering.
You should drive particularly carefully on slip-
pery road surfaces. Avoid sudden accelera-
tion, steering and braking manoeuvres.
i For more information on driving with
snow chains, see (Y page 343). Driving systems
Cruise control
Important safety notes G
WARNING
Do not change down for additional engine
braking on a slippery road surface. This could
cause the drive wheels to lose their grip and
the vehicle could skid. G
WARNING
Cruise control cannot take account of road
and traffic conditions.
Always pay attention to traffic conditions
even when cruise control is activated.
Cruise control is only an aid designed to assist
driving. You are responsible for the vehicle's
speed and for braking in good time. G
WARNING
Do not use cruise control
R in traffic conditions that do not allow you to
drive at a constant speed (e.g. heavy traffic 182

Deactivating variable SPEEDTRONIC G
WARNING
It is no tpossible to deactivate variable Speed-
tronic by braking. There are several ways to deactivate variable
SPEEDTRONIC:
X
Briefly press the cruise control lever for-
wards :.
or
X Briefly press the cruise control lever in the
direction of arrow =.

lever goes out. Variable SPEEDTRONIC is
deactivated.
Cruise control or DISTRONIC PLUS is selec-
ted.
Variable SPEEDTRONIC is automatically
deactivated if:
R you depress the accelerator pedal beyond
the pressure point (kickdown), but only if
your current speed does not differ by more
than 20 km/h from the stored speed. You
will hear a warning tone if this is the case.
R on vehicles with manual transmission, if
you shift to a higher gear and as a result,
the engine speed is too low.
i The last speed stored is cleared when you
switch off the engine. Permanent SPEEDTRONIC You can use the on-board computer to limit
the speed permanently to
avalue between
160 km/h(e.g. for driving on winter tyres) and
the maximum speed ( Ypage 245).
Shortly before the store dspeed is reached, it
appears in the multifunction display.
Permanent SPEEDTRONIC remains active,
even if variable SPEEDTRONIC is deactivated.
You cannot exceed the stored limit speed,
even if you depress the accelerator pedal
beyond the pressure point (kickdown). DISTRONIC PLUS
Important safety notes G
WARNING
Do not change down for additional engine
braking on a slippery road surface. This could
cause the drive wheels to lose their grip and
the vehicle could skid. G
WARNING
DISTRONIC PLUS is only an aid designed to
assist driving. The driver remains fully respon-
sible for the vehicle's distance from other
vehicles, the vehicle's speed and for braking
in good time.
DISTRONIC PLUS does not react in particular
to:
R pedestrians
R stationary obstacles on the road, e.g. stop-
ped or parked vehicles
R oncoming and crossing traffic
DISTRONIC PLUS may not detect narro wvehi-
cles driving in front, e.g. motorcycles, or vehi-
cles driving on a differen tline. Therefore,
always pay attention to traffic conditions even
when DISTRONIC PLUS is activated. Other-
wise, you may fail to recognise dangers in
time, cause an accident and injure yourself
and others. 188
Driving systemsDriving and parking

G
WARNING
DISTRONIC PLUS cannot take account of road
and traffic conditions. If DISTRONIC does not
recognise or no longer recognises the vehicle
in front, do not activate DISTRONIC or, if it is
already active, deactivate it. This is especially
the case:
R before corners
R on filter lanes
R when changing to a lane with faster moving
traffic
R in comple xdriving situations or where lanes
are diverted, e.g. at roadworks on a motor-
way
DISTRONIC PLUS otherwise maintains the
current speed set by you or accelerates up to
the set speed.
DISTRONIC PLUS cannot take account of
weather conditions. Deactivate, or do not
activate, DISTRONIC PLUS:
R if the roads are slippery, snow-covered or
icy. The wheels could lose their grip when
braking or accelerating. The vehicle could
start to skid.
R if the sensors are dirty or there is poor vis-
ibility, e.g. due to snow, rain or fog. Dis-
tance control may be impaired.
Always pay attention to traffic conditions
even when DISTRONIC PLUS is activated.
Otherwise, you may fail to recognise dangers
in time, cause an accident and injure yourself
and others. G
WARNING
DISTRONIC PLUS brakes yourv ehicle up to a
maximum of 4 m/s 2
depending on its speed.
This corresponds to approximately 40% of
your vehicle's maximum braking power. You
must also apply the brakes yourself if this
braking power is not sufficient.
If DISTRONIC PLUS detects a risk of collision
with avehicle in front, an intermittent warning
tone sounds. In addition, the ·distance
warning lamp in the instrument cluster lights
up. Brake to avoid a collision. General notes DISTRONIC PLUS regulates the speed and
automatically helps you maintain the dis-
tance to the vehicle detected in front. DIS-
TRONIC PLUS brakes automatically so that
the set speed is not exceeded.
On long and steep downhill gradients, espe-
cially if the vehicle is laden or towing a trailer,
you must select shift range
1,2or 3in good
time. By doing so, you will make use of the
braking effec tofthe engine. This relieves the
load on the brake system and prevents the
brakes from overheating and wearing too
quickly.
If DISTRONIC PLUS detects a slower-moving
vehicle in front, your vehicle is braked in order
to maintain the preset distance to the vehicle
in front.
If you want DISTRONIC PLUS to assist you,
the radar sensor system must be activated
(Y page 245) and operational.
The radar sensor system is switched off auto-
matically in the vicinity of radio telescope
facilities (Y page 382).
If there is no vehicle in front, DISTRONIC
PLUS operates in the same way as cruise
control in the speed range between
30 km/h and 200 km/h. If avehicle is driving
in front of you, DISTRONIC operates in the
speed range between 0km/h and
200 km/h.
Do not use DISTRONIC PLUS on roads with
steep gradients. Driving systems
