Driving and parking

In addition to driving style, the actual consump-
tion is affected by other factors, such as: R
Load R
Tire pressure R
Cold start R
Choice of route R
Active electrical consumers
These factors are not included in the ECO dis-
play.
An economical driving style specially requires
driving at moderate engine speeds.
Achieving a higher value in the categories
"Acceleration" and "Constant": R
observe the gearshift recommendations. R
drive the vehicle in drive program C or E
(vehicles with a DYNAMIC SELECT button).
On long journeys at a constant speed, e.g. on the
highway, only the outer area for "constant" will
change.
The ECO display summarizes 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. On lon-
ger journeys, there are fewer changes. For more
marked changes, perform a manual rest
( Y
page 178).
For more information on the ECO display, see
( Y
page 177).
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.
There is an increased danger of skidding and
accidents.
Do not shift down for additional engine brak-
ing on a slippery road surface.
Downhill gradients
! On long and steep gradients, you must
reduce the load on the brakes by shifting to a
lower gear in good time. This allows you to
take advantage of engine braking. For this you
must first activate manual gearshifting. This helps you to avoid overheating the brakes and
wearing them out excessively.
When you take advantage of engine braking, it
is possible that a drive wheel will not rotate for
some time, e.g. on a slippery road surface.
This could cause damage to the drive train.
This type of damage is not covered by the
Mercedes-Benz warranty.
Briefly depressing the accelerator pedal on
downhill gradients while the manual drive pro-
gram M is temporarily activated: the automatic
transmission may switch to the last active auto-
matic drive program E or S . The automatic trans-
mission may shift to a higher gear. This can
reduce the engine's braking effect.
Heavy and light loads
G WARNING
If you rest your foot on the brake pedal while
driving, the braking system can overheat. This
increases the stopping distance and can even
cause the braking system to fail. There is a
risk of an accident.
Never use the brake pedal as a footrest. Never
depress the brake pedal and the accelerator
pedal at the same time.
! 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. Drive
on for a short while. This allows the airflow to
cool the brakes more quickly.
Wet roads 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 the vehicle has
been washed or driven through deep water.
You have to depress the brake pedal more
firmly. Maintain a greater distance from 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 145
Driving and parking Z

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 winter-proofed at a qualified
specialist workshop at the onset of winter.
Drive particularly carefully on slippery road sur-
faces. Avoid sudden acceleration, steering and
braking maneuvers. Do not use cruise control or
Distance Pilot DISTRONIC.
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 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.
You should pay special attention to road condi-
tions when temperatures are around freezing
point.
For more information on driving with snow
chains, see ( Y
page 285).
For more information on driving with summer
tires, see ( Y
page 284).
Observe the notes in the "Winter operation" sec-
tion ( Y
page 284).
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 selected manual drive pro-
gram M ( Y
page 135). By doing so, you will make
use of the braking effect of the engine. This relieves the load on the brake system and pre-
vents the brakes from overheating and wearing
too quickly.
When the engine is running, you can use the
cruise control lever to limit the speed to any
speed between 20 mph (30 km/h) and the tech-
nically permitted maximum speed of the vehicle.
Use cruise control only if road and traffic con-
ditions make it appropriate to maintain a steady
speed for a prolonged period.
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 con-
trol 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 accel-
erating could cause the drive wheels to lose
traction and the vehicle could then skid R
in 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.

i When you switch off the engine, the last
speed stored is cleared.
Distance Pilot DISTRONIC
General notes Distance Pilot DISTRONIC regulates the speed
and automatically helps you maintain the dis-
tance to the vehicle detected in front. Vehicles
are detected with the aid of the radar sensor
system. Distance Pilot DISTRONIC brakes auto-
matically to avoid exceeding the set speed or to
maintain the designated distance from the vehi-
cle in front.
If Distance Pilot DISTRONIC detects that there is
a risk of a collision, you will be warned visually
and acoustically. Without your intervention, Dis-
tance Pilot DISTRONIC cannot prevent a colli-
sion. 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.
Distance Pilot DISTRONIC operates in the range
between 0 mph (0 km/h) and 120 mph
(200 km/h).
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 wear-
ing too qui ckly.
Do not use Distance Pilot DISTRONIC on roads
with steep gradients.
For Distance Pilot DISTRONIC to assist you
when driving, the radar sensor system must be
operational.
Since Distance Pilot DISTRONIC 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. i USA only: This device has been approved by
the FCC as a "Vehicular Radar System". The

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.
i Distance Pilot DISTRONIC is deactivated
when you depress the brake, except when the
vehicle is stationary.
Selecting the drive program Distance Pilot DISTRONIC supports a sporty
driving style when you select the S+ drive pro-
gram (Mercedes-AMG vehicles only), S
( Y
page 133) or the manual drive program
( Y
page 135). Acceleration behind the vehicle in
front or to the set speed is then noticeably more
dynamic. If you have selected the E (Mercedes-
AMG vehicles: C ) drive program, the vehicle
accelerates more gently. This setting is recom-
mended in stop-and-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 45 mph (70 km/h) R
Distance Pilot DISTRONIC is maintaining the
distance to a vehicle in front R
you switch on the appropriate turn signal R
Distance Pilot DISTRONIC does not currently
detect a danger of collision
If these conditions are fulfilled, your vehicle is
accelerated. Acceleration will be interrupted if
changing lanes takes too long or if the distance
between your vehicle and the vehicle in front
becomes too small.
Stopping
If Distance Pilot DISTRONIC detects that the
vehicle in front is stopping, it brakes your vehicle
until it is stationary.
Once your vehicle is stationary, it remains sta-
tionary 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 Distance Pilot DISTRONIC is activated,
the transmission is shifted automatically to
position 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 Distance Pilot DISTRONIC is
activated when the vehicle is stationary and: R
a system malfunction occurs. R
the power supply is insufficient.
If a malfunction occurs, the transmission may
also shift into position P automatically.
Setting a speed Keep in mind that it may take a brief moment
until the vehicle has accelerated or braked to
the speed set. X
Press the cruise control lever up C for a
higher speed or down D for a lower speed.X
To adjust the set speed in1 mphincre-
ments (1 km/hincrements): briefly press
the cruise control lever up C or down D to
the pressure point.
The last stored speed increases or decreases
in 1 mph (1 km/h) increments. X
To adjust the set speed in5 mphincre-
ments (10 km/hincrements): briefly press
the cruise control lever up C or down D to
the pressure point.
The last stored speed increases or decreases
in 5 mph (10 km/h) increments.
i Distance Pilot DISTRONIC is not deactivated
if you depress the accelerator pedal. If you
accelerate to overtake, Distance Pilot
DISTRONIC adjusts the vehicle's speed to the
last speed stored after you have finished over-
taking.
Setting a specified minimum distance
You can set the specified minimum distance for
Distance Pilot DISTRONIC by varying the time
span between one and two seconds. With this
function you can set the minimum distance that
Distance Pilot DISTRONIC maintains to the vehi-
cle in front, dependent on vehicle speed. You
can see this distance in the multifunction dis-
play ( Y

Parking Assist PARKTRONIC
Important safety notes Parking Assist PARKTRONIC is an electronic
parking aid with ultrasound. It monitors the area
around your vehicle using six sensors in the
front bumper and six sensors in the rear
bumper. Parking Assist PARKTRONIC visually
and audibly indicates the distance between your
vehicle and an object.
Parking Assist PARKTRONIC is only an aid. It is
not a replacement for your attention to your
immediate surroundings. You are always
responsible for safe maneuvering, parking and
exiting a parking space. When maneuvering,
parking or pulling out of a parking space, make
sure that there are no persons, animals or
objects in the area in which you are maneuver-
ing.
! When parking, pay particular attention to
objects above or below the sensors, such as
flower pots or trailer drawbars. Parking Assist
PARKTRONIC does not detect such objects
when they are in the immediate vicinity of the
vehicle. You could damage the vehicle or the
objects.
The sensors may not detect snow and other
objects that absorb ultrasonic waves.
Ultrasonic sources such as an automatic car
wash, the compressed-air brakes of a truck or
a pneumatic drill could cause Parking Assist
PARKTRONIC to malfunction.
Parking Assist PARKTRONIC may not function
correctly on uneven terrain.
Parking Assist PARKTRONIC is activated auto-
matically when you: R
switch on the ignition R
shift the transmission to position D , R or NR
release the electric parking brake
Parking Assist PARKTRONIC is deactivated at
speeds above 11 mph (18 km/h). It is reactiva-
ted at lower speeds. Range of the sensors General notes Parking Assist PARKTRONIC does not take into
account obstacles located: R
below the detection range, e.g. people, ani-
mals or objects. R
above the detection range, e.g. overhanging
loads, tail sections or loading ramps of goods
vehicles.
