In addition to driving style, the actual consump-
tion is affected by other factors, such as:
R load
R tyre pressure
R cold start
R choice of route
R the use of electrical consumers
These factors are not included in the ECO dis-
play.
An economical driving style involves driving at a
moderate engine speed.
To achieve a higher value in the categories
"Acceleration" and "Constant":
R observe the gearshift recommendation
R drive the vehicle in drive program Cor E.
On long journeys at a constant speed, e.g. on the motorway, only the outer area for "Constant"
will change.
The ECO display summarises the driving style
from the start of the journey to its completion.
Therefore, there are more marked changes in
the outer areas at the start of a journey. During
a prolonged driving time, these changes are
smaller. For more marked changes, perform a
manual reset (Y page 203).
Further information on the ECO display
(Y page 202). Braking
Important safety notes 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.
Downhill gradients Change into a lower gear in good time on long
and steep downhill gradients. Take particular
note of this when driving a laden vehicle.
This also applies if you have activated cruise
control, the limiter or Distance Pilot DISTRONIC. This will use the braking effect of the engine, so
less braking will be required to maintain vehicle
speed. This relieves the load on the brake sys-
tem and prevents the brakes from overheating
and wearing too quickly.
Heavy and light loads G
WARNING
The braking system can overheat if you leave your foot on the brake pedal while driving.
This increases the braking distance and could
even cause the braking system to fail. There is
a risk of an accident.
Never use the brake pedal as a footrest. Do
not simultaneously depress both the brake
pedal and the accelerator pedal while driving.
! Depressing the brake pedal constantly
results in excessive and premature wear to
the brake pads.
If the brakes have been subjected to a heavy
load, do not stop the vehicle immediately, but
drive on for a short while. This allows the airflow
to cool the brakes more quickly.
If the brakes have been used only moderately,
you should occasionally test their effectiveness.
To do this, brake more firmly from a higher
speed while paying attention to the traffic con-
ditions. This improves the grip of the brakes.
Wet road surfaces If you have driven for a long time in heavy rain
without braking, there may be a delayed reac-
tion from the brakes when braking for the first
time. This may also occur after a car wash or
after driving through deep water.
You will have to depress the brake pedal more
firmly. Maintain a greater distance to the vehicle in front.
After driving on a wet road or having the vehicle
washed, brake firmly while paying attention to
the traffic conditions. This will warm up the
brake discs, thereby drying them more quickly
and protecting them against corrosion. Driving tips

Winter driving
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. 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.
! Take care not to damage the sealing strip
and the moulding on the side of the rear win- dow when scraping ice off the rear window.
Have your vehicle winterproofed at a qualified
specialist workshop at the onset of winter.
You should drive particularly carefully on slip-
pery road surfaces. Avoid sudden acceleration,
steering and braking manoeuvres. Do not use
cruise control.
If the vehicle threatens to skid or cannot be
stopped when moving at low speed:
X Shift the transmission to position N.
X Try to bring the vehicle under control by using
corrective steering.
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 dis-
played 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. The vehicle could
skid if you fail to adapt your driving style. Always adapt your driving style and drive at a speed to
suit the prevailing weather conditions.
You should pay special attention to road condi-
tions when temperatures are around freezing
point.

tyres (Y page 306).
Observe the notes in the "Winter operation" sec-
tion (Y page 306). 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 lower gear in good time.
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 set any
road speed above 30 km/h.
Important safety notes If you fail to adapt your driving style, cruise con-
trol can neither reduce the risk of accident nor
override the laws of physics. Cruise control can-
not take road, weather and traffic conditions
into account. 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 maintaining lane.
Do not use cruise control:
R in road and traffic conditions which do not
allow you to maintain a constant speed, e.g.
heavy traffic or winding roads.
R on slippery roads. Braking or accelerating
may 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. Driving systems

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 auto-
matically braking the vehicle.
Storing or calling up the speed G
WARNING
If you call up a stored speed and this is dif-
ferent from the current speed, the vehicle
accelerates or brakes. If you do not know
what the stored speed is, the vehicle may
accelerate or brake unexpectedly. There is a
risk of an accident.
Take the traffic conditions into account
before calling up the stored speed. If you do
not know what the stored speed is, store the
desired speed again.
X Briefly pull the cruise control lever towards

Distance Pilot DISTRONIC operates in the range
between 0 km/h and 200 km/h.
Do not use Distance Pilot DISTRONIC while driv-
ing on roads with steep gradients.
Important safety notes G
WARNING
Distance Pilot DISTRONIC does not recognise
R people or animals
R stationary objects on the road, e.g. stopped
or parked vehicles
R oncoming vehicles or crossing traffic
As a result, Distance Pilot DISTRONIC may
neither give warnings nor intervene in such
situations. There is a risk of an accident.
Always pay careful attention to the traffic sit-
uation and be ready to brake. G
WARNING
Distance Pilot DISTRONIC cannot always
clearly identify other road users and complex
traffic situations.
In such cases, Distance Pilot DISTRONIC may:
R give an unnecessary warning and then
brake the vehicle
R neither give a warning nor intervene
R accelerate or brake unexpectedly
There is a risk of an accident.
Continue to drive carefully and be ready to
brake, especially if Distance Pilot DISTRONIC
warns you. G
WARNING
Distance Pilot DISTRONIC brakes your vehicle with up to 50% of the maximum possible
deceleration. If this deceleration is not suffi-
cient, Distance Pilot DISTRONIC alerts you
with a visual and acoustic warning. There is a
risk of an accident.
Apply the brakes yourself in these situations
and try to take evasive action.
! When Distance Pilot DISTRONIC or the
HOLD function is activated, the vehicle
brakes automatically in certain situations. To avoid damage to the vehicle, deactivate
Distance Pilot DISTRONIC and the HOLD
function in the following or similar situations:
R when towing away
R in a car wash
If you fail to adapt your driving style, Distance
Pilot DISTRONIC can neither reduce the risk of
an accident nor override the laws of physics.
Distance Pilot DISTRONIC cannot take into
account road, weather or traffic conditions. Dis-
tance Pilot DISTRONIC 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 lane.
Do not use Distance Pilot DISTRONIC:
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 smooth or slippery roads. Braking or accel-
erating can cause the drive wheels to lose
traction and the vehicle could then skid
R when visibility is poor, e.g. due to fog, heavy
rain or snow
Distance Pilot DISTRONIC may not detect nar-
row vehicles driving in front, e.g. motorcycles, or
vehicles driving on a different line.
In particular, the detection of obstacles can be
impaired in the case of:
R dirt on the sensors or obscured sensors
R snow or heavy rain
R interference by other radar sources
R the possibility of strong radar reflections, for
example, in multi-storey car parks
If Distance Pilot DISTRONIC no longer detects a vehicle in front, it may unexpectedly accelerate
to the speed stored.
This speed can:
R be too high for a filter lane or a slip road
R be so high in the right lane that you pass vehi-
cles driving on the left
R be so high in the left lane that you pass vehi-
cles driving on the right
If there is a change of drivers, advise the new
driver of the speed stored. 162

Activating at the current speed/last
stored speed G
WARNING
If you call up a stored speed and this is dif-
ferent from the current speed, the vehicle
accelerates or brakes. If you do not know
what the stored speed is, the vehicle may
accelerate or brake unexpectedly. There is a
risk of an accident.
Take the traffic conditions into account
before calling up the stored speed. If you do
not know what the stored speed is, store the
desired speed again.
X Briefly pull the cruise control lever towards
you ?.
X Remove your foot from the accelerator pedal.
The first time Distance Pilot DISTRONIC is
activated, it stores the current speed or reg-
ulates the speed of the vehicle to the previ-
ously stored speed.
Pulling away and driving
X If you want to pull away with Distance
Pilot DISTRONIC: remove your foot from the
brake pedal.
X Briefly pull the cruise control lever towards
you ?.
or X If Distance Pilot DISTRONIC is activated:
accelerate briefly.
Your vehicle pulls away and adapts its speed
to that of the vehicle in front. If no vehicle is
detected in front, your vehicle accelerates to the set speed.
The vehicle can also pull away when it is facing
an unidentified obstacle or is driving on a differ-
ent line from another vehicle. The vehicle then
brakes automatically. Be ready to brake at all
times.
If there is no vehicle in front, Distance Pilot
DISTRONIC operates in the same way as cruise control.
If Distance Pilot DISTRONIC detects a slower-
moving vehicle in front, it brakes your vehicle. In
this way, the distance you have selected is main- tained.
If Distance Pilot DISTRONIC detects a faster-
moving vehicle in front, it increases the driving speed. However, the vehicle is only accelerated
up to the speed you have stored.
Selecting the drive program
All vehicles (except AMG vehicles): Distance
Pilot DISTRONIC supports a sporty driving style when you have selected the Sor S+ drive pro-
gram (Y page 139). Acceleration behind the
vehicle in front or to the set speed is then notice- ably more dynamic. If you have selected the Cor
E drive program, the vehicle accelerates more
gently. This setting is recommended in stop-
start traffic.
AMG vehicles: Distance Pilot DISTRONIC sup-
ports a sporty driving style when you have selec- ted the S,S+ orMdrive program (Y page 140).
Acceleration behind the vehicle in front or to the set speed is then noticeably more dynamic.
When you select the Cdrive program, the vehi-
cle accelerates more gently. This setting is rec- ommended in stop-start traffic.
Changing lanes
If when driving on multilane roads you wish to
change to the overtaking lane, Distance Pilot
DISTRONIC supports you if:
R you are driving faster than 70 km/h
R Distance Pilot DISTRONIC is maintaining the
distance to a vehicle in front
R you switch on the respective turn signal
R Distance Pilot DISTRONIC does not currently
detect a danger of collision
If these conditions are met, your vehicle is accel-
erated. Acceleration will be interrupted if chang- ing lanes takes too long or if the distance
between your vehicle and the vehicle in front
becomes too small.
