G DANGER
If th e exhaust pipe is blocke d or adequate
ventilation is no t possible, poisonous gase s
suc h as carbon monoxide (CO) may ente r th e
vehicle. This is th e case, e.g. if th e vehicl e
become s trapped in snow. There is a ris k of
fatal injury.
If you leav e th e engin e or th e auxiliary heating
running, mak e sur e th e exhaust pipe and area
around th e vehicl e are clear of snow. To
ensur e an adequate supply of fresh air, open a
window on th e side of th e vehicl e that is no t
facing int o th e wind.
Hav e your vehicl e winter-proofe d at a quali-
fie d specialist workshop at th e onset of win -
ter.
Drive particularly carefully on slipper y road
surfaces. Avoid sudde n acceleration , steering
and brakin g maneuvers . Do no t use th e cruise
control or DISTRONI C PLUS.
If th e vehicl e threaten s to skid or canno t be
stoppe d when moving at low speed:X
Shift th e transmission to position N .X
Try to bring th e vehicl e under control usin g
corrective steering .
The outside temperature indicator is no t
designed to serve as an ice-warnin g device
and is therefor e unsuitable for that purpose .
Changes in th e outside temperature are dis-
played after a short delay.
Indicate d temperatures jus t abov e th e freez -
in g p oin t d o no t guarantee that th e road sur -
fac e is free of ice . The road may still be icy,
especially in wooded areas or on bridges .
You should pay special attention to road con-
dition s when temperatures are around freez -
in g point.

G WARNIN G
If you drive on a steep inclin e at an angle or
tur n when drivin g on an incline, th e vehicl e
could slip sideways, ti p and rollover. There is a
ris k of an accident.
Always drive on a steep inclin e in th e lin e of
fall (straight up or down ) and do no t tur n th e
vehicle.
G WARNIN G
Flammabl e material suc h as leaves, grass or
twigs may ignit e if they come int o contact wit h
hot part s of th e exhaust system. There is a ris k
of fire.
Whe n drivin g off roa d or on unpaved roads,
chec k th e vehicle's underside regularly. In
particular, remove part s of plants or other
flammabl e materials whic h hav e become
trapped . In th e cas e of damage, contact a
qualified specialist workshop .
! There is a ris k of damag e to th e vehicl e if:R
th e vehicl e become s stuck , e.g. on a high
cur b or an unpaved road R
you drive to o fas t ove r an obstacle, e.g. a
cur b or a hole in th e road R
a heav y objec t strikes th e undercarriage
or part s of th e chassi s
In situation s lik e this, th e body, th e under-
carriage, chassi s parts, wheels or tires
could be damaged without th e damag e
bein g visible. Components damaged in this
way can unexpectedly fail or, in th e cas e of
an accident, no longer withstand th e strain
they are designed to .
If th e underbody panelin g is damaged,
combustible materials suc h as leaves,
gras s or twigs can gather between th e
underbody and th e underbody paneling. If
these materials come in contact wit h hot
part s of th e exhaust system, they can catch
fire.180
Driving tips
Driving and parking

R
Activate DSR. If this is not sufficient, brake
gently. When doing so, make sure that the
vehicle is facing in the direction of the line
of fall. R
Check that the brakes are working normally
after a long downhill stretch.
Off-road ABS is activated when the off-road
program is selected.
At speeds below 18 mph (30 km/h), the front
wheels lock cyclically during braking. The dig-
ging-in effect achieved in the process reduces
the stopping distance on off-road terrain. The
steerability of the vehicle is considerably
reduced if the wheels lock.
Driving systems
Cruise Control
General notes Cruise control maintains a constant road
speed for you. It brakes automatically in order
to avoid exceeding the set speed. On long and
steep downhill gradients, especially if the
vehicle is laden, you must select a low gear in
good time. You need to have previously selec-
ted manual gearshifting M ( Y
page 166). 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 con-
ditions make it appropriate to maintain a
steady speed for a prolonged period. You can
store any road speed above 20 mph
(30 km/h).
The speed indicated in the speedometer may
differ slightly from the speed stored.
Important safety notes
If you fail to adapt your driving style, cruise
control can neither reduce the risk of an acci-
dent nor 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 dis-
tance to the vehicle in front, for 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 a constant speed e.g.
in heavy traffic or on winding roads R
on slippery road surfaces. Braking or accel-
erating 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 a change of drivers, advise the new
driver of the speed stored.

You can store the current speed if you are
driving faster than 20 mph (30 km/h). X
Accelerate the vehicle to the desired
speed. X
Briefly press the cruise control lever up C
or down

To prevent damage to the vehicle, deacti-
vate DISTRONIC PLUS and the HOLD func-
tion in the following or other similar situa-
tions: R
when towing the vehicle R
in the car wash
If you fail to adapt your driving style,
DISTRONIC PLUS can neither reduce the risk
of accident nor override the laws of physics.
DISTRONIC PLUS cannot take into account
the road, traffic and weather conditions.
DISTRONIC PLUS is only an aid. You are
responsible for the distance to the vehicle in
front, for vehicle speed, for braking in good
time and for staying in your lane.
Do not use DISTRONIC PLUS: R
in road and traffic conditions which do not
allow you to maintain a constant speed, e.g.
in heavy traffic or on winding roads R
on slippery road surfaces. Braking or accel-
erating 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 a different line.
In particular, the detection of obstacles can
be impaired if: R
there is dirt on the sensors or anything else
covering the sensors R
there is snow or heavy rain R
there is interference by other radar sources R
there are strong radar reflections, for
example, in parking garages
If DISTRONIC PLUS no longer detects a vehi-
cle in front, DISTRONIC PLUS may unexpect-
edly accelerate the vehicle to the stored
speed. This speed may: R
be too high if you are driving in a filter lane
or an exit lane R
be so high when driving in the right-hand
lane that you overtake vehicles in the left-
hand lane R
be so high when driving in the left-hand lane
that you overtake vehicles in the right-hand
lane
If there is a change of drivers, advise the new
driver of the speed stored.

the front-passenger door and rear doors
must be closed.
Activating X
Briefly pull the cruise control lever towards
you

If these conditions are fulfilled, your vehicle is
accelerated. Acceleration will be interrupted
if changing lanes takes too long or if the dis-
tance between your vehicle and the vehicle in
front becomes too small.
Stopping
G WARNING
When leaving the vehicle, even if it is braked
only by DISTRONIC PLUS, it could roll away if: R
there is a malfunction in the system or in
the voltage supply. R
DISTRONIC PLUS has been deactivated
with the cruise control lever, e.g. by a vehi-
cle occupant or from outside the vehicle. R
the electrical system in the engine com-
partment, the battery or the fuses have
been tampered with. R
the battery is disconnected. R
the accelerator pedal has been depressed,
e.g. by a vehicle occupant.
There is a risk of an accident.
If you wish to exit the vehicle, always turn off
DISTRONIC PLUS and secure the vehicle
against rolling away.
For further information on deactivating
DISTRONIC PLUS ( Y
page 190).
If DISTRONIC PLUS detects that the vehicle in
front is stopping, it brakes your vehicle until it
is stationary.
Once your vehicle is stationary, it remains
stationary and you do not need to depress the
brake.
i After a time, the electric parking brake
secures the vehicle and relieves the service
brake.
i Depending on the specified minimum dis-
tance, your vehicle will come to a standstill
at a sufficient distance behind the vehicle in
front. The specified minimum distance is
set using the control on the cruise control
lever. When DISTRONIC PLUS is activated, the
transmission is shifted automatically to posi-
tion P if: R
the driver's seat belt is not fastened and the
driver's door is open. R
the engine is switched off, unless it is auto-
matically switched off by the ECO start/
stop function.
The electric parking brake secures the vehicle
automatically if DISTRONIC PLUS is activated
when the vehicle is stationary and: R
a system malfunction occurs. R
the power supply is not sufficient.
If a malfunction in the electric parking brake
occurs, then the transmission may also be
shifted into position P automatically.
