Winter driving
General 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.
There is an increased danger of skidding and
accidents.
Do not shift down for additional engine
braking on aslippery road surface. G
DANGER
If the exhaust pipe is blocked or adequate
ventilation is not possible,p oisonous 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 arisk 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
aw indow on the side of the vehicle that is not
facing into the wind.
Have your vehicle winterproofed at aqualified
specialist workshop at the onset of winter.
Observe the notes in the "Winter operation"
section (Y page 314).
Driving with summer tires Observe the notes in the "Winter operation"
section (Y
page 314).
Slippery road surfaces G
WARNING
If you shift down on aslippery road surface in
an attempt to increase the engine's braking
effect, the drive wheels could lose their grip.
There is an increased danger of skidding and
accidents.
Do not shift down for additional engine
braking on aslippery road surface. If the vehicle threatens to skid or cannot be
stopped when moving at low speed:
X Shift the transmission to position N.
Drive particularlyc arefully on slippery road
surfaces. Avoid sudden acceleration, steering
and braking maneuvers. Do not use the cruise
control or DISTRONIC PLUS.
The outside temperature indicator is not
designed to serve as an ice-warning device
and is therefore unsuitablef or that purpose.
Changes in the outside temperature are
displayed after ashort delay.
Indicated temperatures just above the
freezing point do not guarantee that the road
surface is free of ice. The road may still be icy,
especially in wooded areas or on bridges. You
should pay special attention to road
conditions when temperatures are around
freezing point.
i For more information on driving with
snow chains, see (Y page 315). Driving systems
Cruise control
General notes Cruise control maintains
aconstant road
speed for you. It brakes automaticallyino rder
to avoid exceeding the set speed. On long and
steep downhill gradients, especially if the
vehicle is laden, you must select alow gear in
good time. For this, you will need to have
selected manual drive program
M(Y page 147). By doing so, you will make
use of the braking effect of the engine. This
relieves the load on the brake system and
prevents the brakes from overheating and
wearing too quickly.
Use cruise control only if road and traffic
conditions make it appropriate to maintain a
steady speed for aprolonged period. You can
store any road speed above 20 mph
(30 km/h). 160
Driving systemsDriving and parking

Important safety notes
If you fail to adapt your driving style, cruise
control can neither reduce th eriskofan
acciden tnor override the laws of physics.
Cruise control cannot take into account the
road, traffic and weather conditions. Cruise
control is only an aid. You are responsible for
the distance to the vehicle in front,f or vehicle
speed, for braking in good time and for
staying in your lane.
Do not use cruise control:
R in road and traffic conditions which do not
allow you to maintain aconstant speed e.g.
in heavy traffic or on winding roads
R on slippery road surfaces. Brakin gor
accelerating could cause the drive wheels
to lose traction and the vehicle could then
skid
R when there is poor visibility, e.g. due to fog,
heavy rain or snow
If there is achange of drivers, advise the new
driver of the speed stored.
Cruise control lever 001A
To activate or increase speed
0010 To activate or reduce speed
0023 To deactivate cruise control
0021 To activate at the current speed/last
stored speed
When you activate cruise control, the stored
speed is shown in the multifunction display
for five seconds. Activation conditions To activate cruise control, all of the following
activation conditions must be fulfilled:
R the electric parking brake must be
released.
R you are driving faster than
20 mph(30 km/h).
R ESP ®
must be active, but not intervening.
R on vehicles with automatic transmission,
the selector lever must be in position D.
Storing, maintaining and calling up a
speed Storing and maintaining the current
speed
You can store the current speed if you are
driving faster than 20 mph (30km/h).
X Accelerate the vehicle to the desired
speed.
X Briefly press the cruise control lever
up 001A or down 0010.
X Remove your foot from the accelerator
pedal.
Cruise control is activated. The vehicle
automatically maintains the stored speed.
i Cruise control may be unable to maintain
the stored speed on uphill gradients. The
stored speed is resumed when the gradient
evens out. Cruise control maintains the
stored speed on downhill gradients by
automatically applying the brakes.
Storing the current speed or calling up the
last stored speed G
WARNING
If you call up the stored speed and it differs
from the current speed, the vehicle
accelerates or decelerates. If you do not know
the stored speed, the vehicle could accelerate
or brake unexpectedly. There is arisk of an
accident.
Pay attention to the road and traffic
conditions before calling up the stored speed. Driving systems

Every time the cruise control lever is
pressed up 001Aor down 0010the last speed
stored is increased or reduced.
i Cruise control is not deactivated if you
depress the accelerator pedal. For
example, if you accelerate briefly to
overtake, cruise control adjusts the
vehicle's speed to the last speed stored
after you have finished overtaking. Deactivating cruise control There are several ways to deactivate cruise
control:
X
Briefly press the cruise control lever
forwards 0023.
or
X Brake.
Cruise control is automatically deactivated if:
R the vehicle is secured with the electric
parking brake
R you are driving at less than 20 mph
(30 km/h)
R ESP ®
intervenes or you deactivate ESP ®
R you shift the transmission to position N
while driving
If cruise control is deactivated, you will hear
aw arning tone. You will see the Cruise Control Off message in the multifunction
display for approximately five seconds.
i When you switch off the engine, the last
speed stored is cleared. DISTRONIC PLUS
General notes DISTRONIC PLUS regulates the speed and
automatically helps you maintain the
distance to the vehicle detected in front.
Vehicles are detected with the aid of the radar
sensor system. DISTRONIC PLUS brakes
automatically so that the set speed is not
exceeded.
Change into
alower gear in good time on long
and steep downhill gradients. This is
especially important if the vehicle is laden. By
doing so, you will make use of the braking
effect of the engine. This relieves the load on
the brake system and prevent sthe brakes
from overheating and wearing too quickly.
If DISTRONIC PLUS detect sthat there is arisk
of ac ollision, you will be warned visually and
acoustically. DISTRONIC PLUS cannot
prevent acollision without your intervention. 162
Driving systemsDriving and parking

An intermittent warning tone will then sound
and the distance warning lamp will light up in
the instrument cluster .Brake immediatel yin
order to increase the distance to the vehicle
in front or take evasive action provided it is
safe to do so.
For DISTRONI CPLUStoa ssist you, the radar
sensor system must be operational.
DISTRONIC PLUS is automatically
deactivated if:
R you are driving slower than 15 mph
(25 km/h) and there is no longer avehicle
in front or
R the vehicle in front is no longer detected
If there is no vehicle in front,D ISTRONIC
PLUS operates in the same way as cruise
control in the speed range between 20 mph
(30 km/h) and 120 mph (200 km/h) .Ifa
vehicle is driving in front of you, it operates in
the speed range between 0mph (0 km/h) and
120 mph (200 km/h).
Do not use DISTRONIC PLUS while driving on
roads with steep gradients.
As DISTRONIC PLUS transmits radar waves,
it can resemble the radar detector softhe
responsible authorities. You can refer to the
relevant chapter in the Operator's Manual if
question sare asked about this.

R on slippery road surfaces. Brakin gor
accelerating could cause the drive wheels
to lose traction and the vehicle could then
skid
R when there is poor visibility, e.g. due to fog,
heavy rain or snow
DISTRONIC PLUS may not detect narrow
vehicles driving in front,e .g. motorcycles, or
vehicles driving on adifferent line.
In particular, the detection of obstacles can
be impaired if:
R dirt on the sensors or anything else
coverin gthe sensors
R snow or heavy rain
R interferenc ebyother radar sources
R strongr adar reflections, for example, in
