Have your vehicle winterproofed at a qualified
specialist workshop at the onset of winter.
Drive particularly carefully on slippery road
surfaces. Avoid sudden acceleration, steering
and braking maneuvers. Do not use the cruise
control or DISTRONIC PLUS.
If the vehicle threatens to skid or cannot be
stopped when moving at low speed:
X Shift the transmission to position N.
The outside temperature indicator is not
designed to serve as an ice-warning device
and is therefore unsuitable for that purpose.
Changes in the outside temperature are
displayed after a short 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.

Mercedes-Benz Intelligent Drive
Mercedes-Benz Intelligent Drive stands for
innovative driver assistance and safety
systems which enhance comfort and support
the driver in critical situations. With these
intelligent co-ordinated systems Mercedes-
Benz has set a milestone on the path towards
autonomous driving.
Mercedes-Benz Intelligent Drive embraces all
elements of active and passive safety in one
well thought out system – for the safety of the
vehicle occupants and that of other road
users. Further information on driving safety systems
(Y page 70). Cruise control
Important safety notes Cruise control maintains a constant road
speed for you. It brakes automatically in order
to avoid exceeding the set speed. Change into
a lower 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 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 a prolonged period. You can
store any road speed above 20 mph
(30 km/h).
If you fail to adapt your driving style, cruise
control can neither reduce the risk of an
accident 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 distance 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
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 a change of drivers, advise the new
driver of the speed stored. Driving systems

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. Driving systems
201Driving and parking Z 

Change into a lower 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 prevents the brakes
from overheating and wearing too quickly.
If DISTRONIC PLUS detects that there is a risk
of a collision, you will be warned visually and
acoustically. DISTRONIC PLUS cannot
prevent a collision without your intervention.
An intermittent warning tone will then sound
and the distance warning lamp will light up in
the instrument cluster. Brake immediately in
order to increase the distance to the vehicle
in front or take evasive action provided it is
safe to do so.
DISTRONIC PLUS operates in range between
0 mph (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 detectors of the
responsible authorities. You can refer to the
relevant chapter in the Operator's Manual if
questions are asked about this.

Driving systemsDriving and parking 

Crossing vehicles
DISTRONIC PLUS may mistakenly detect
vehicles that are crossing your lane.
Activating DISTRONIC PLUS at traffic lights
with crossing traffic, for example, could cause
your vehicle to pull away unintentionally.
DISTRONIC PLUS with Steering Assist General notes
DISTRONIC PLUS Steering Assist helps you
to drive in the middle of the lane by means of
moderate steering interventions at speeds of
0 - 125 mph (0 - 200 km/h).
DISTRONIC PLUS Steering Assist monitors
the area in front of your vehicle by means of
camera system 0043at the top of the
windshield.
At speeds of more than 37 mph (60 km/h),
DISTRONIC PLUS Steering Assist focuses on
lane markings that are present.
At speeds of 0 - 37 mph (0 - 60 km/h),
DISTRONIC PLUS Steering Assist focuses on
the vehicle in front, taking into account lane markings, e.g. when following vehicles in a
traffic jam.
DISTRONIC PLUS must be active in order for
the function to be available.
Important safety notes
If you fail to adapt your driving style,
DISTRONIC PLUS Steering Assist can neither
reduce the risk of an accident nor override the
laws of physics. DISTRONIC PLUS Steering
Assist cannot take into account road,
weather or traffic conditions. DISTRONIC
PLUS Steering Assist 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.
DISTRONIC PLUS Steering Assist does not
detect road and traffic conditions. If you are
following a vehicle which is driving towards
the edge of the road, your vehicle could come
into contact with the curb or other road
boundaries. In the case of deviations in road
markings, beware of other road users, e.g.
cyclists, that are in the direct vicinity of your
vehicle.
Obstacles such as building site huts on the
lane or projecting out into the lane are not
detected.
An inappropriate steering intervention, e.g.
after intentionally driving over a lane marking,
can be corrected at any time if you steer
slightly in the opposite direction.
DISTRONIC PLUS Steering Assist cannot
continuously keep your vehicle in lane. In
some cases, the steering intervention is not
sufficient to bring the vehicle back to the lane.
In such cases, you must steer the vehicle
yourself to ensure that it does not leave the
lane. 210
