eration processes):
R the outer area fills up and the
inner area lights up green: antic-
ipatory driving, keeping your dis- tance and early release of the
accelerator. The vehicle can
coast without use of the brakes.

unnecessary acceleration and
deceleration
R the outer area empties and the
inner area is grey: fluctuations in
speed The three inner areas display the current driv-
ing style and light up green as a result of a
particularly economical driving style.
Depending on the driving situation, up to two
areas may light up simultaneously.
At the beginning of the journey, the three
outer areas are empty and fill up as a result of economical driving. A higher level indicates a more economical driving style. If the three
outer areas are completely filled at the same 212

nomical driving style for the selected settings
and prevailing conditions. The ECO display
border lights up.
The ECO display does not indicate the actual fuel consumption. The additionally achieved
range displayed under Bonus fr. start Bonus fr. start
does not indicate a fixed consumption reduc-
tion.
In addition to driving style, the actual con-
sumption 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 "smooth driving":
R observe the gearshift recommendation
R drive the vehicle in drive program E(vehi-
cles with the AGILITY SELECT switch)
On long journeys at a constant speed, e.g. on the motorway, only the outer area for "con-
stant" 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. Dur- ing a prolonged driving time, these changes
are smaller. For more marked changes, per-
form a manual rest (Y page 299).

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 and
when towing a trailer.
This also applies if cruise control, DISTRONIC
PLUS or SPEEDTRONIC are activated.
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 system 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 heavy demands are made on the brakes, do not park the vehicle immediately. Drive on for
a short while. This allows the airflow to cool
the brakes more quickly. Driving

Pay particular attention in the following traffic
situations:
R Cornering, entering and exiting a bend
R Vehicles which are not driving in the middle
of their lane
R Other vehicles changing lane
R Narrow vehicles
R Obstructions and stationary vehicles
R Crossing vehicles
In such situations, brake if necessary.
DISTRONIC PLUS is then deactivated.
Cornering, entering and exiting a bend The ability of DISTRONIC PLUS to detect vehi-
cles when cornering is limited. Your vehicle
may brake unexpectedly or late.
Vehicles which are not driving in the mid- dle of their lane DISTRONIC PLUS may not detect vehicles
which are not driving in the middle of their Driving systems

lane. The distance to the vehicle in front will
be too short.
Other vehicles changing lane DISTRONIC PLUS has not detected the vehi-
cle cutting in yet. The distance to this vehicle will be too short.
Narrow vehicles DISTRONIC PLUS has not yet detected the
vehicle in front on the edge of the carriageway
because of its narrow width. The distance to
the vehicle in front will be too short.
Obstructions and stationary vehicles DISTRONIC PLUS does not brake for obsta-
cles or stationary vehicles. If, for example, the
detected vehicle turns a corner and reveals
an obstacle or stationary vehicle, DISTRONIC PLUS will not brake for these.
Crossing vehicles DISTRONIC PLUS may mistakenly detect
vehicles that are crossing your lane. Activat-
ing DISTRONIC PLUS at traffic lights with
crossing traffic, for example, could cause
your vehicle to pull away unintentionally.
DISTRONIC PLUS with Steering Assist
and Stop&Go Pilot General notes
DISTRONIC PLUS with Steering Assist and
Stop&Go Pilot aids you in keeping the vehicle
in the centre of the driving lane by means of
moderate steering interventions in a speed
range from 0 - 200 km/h.
It monitors the area in front of your vehicle by means of camera system :at the top of the
windscreen. 230
Driving systemsDriving and parking

Also observe the important safety notes for
DISTRONIC PLUS (Y page 222).
The steering interventions are carried out
with a limited steering moment. The system
requires the driver to keep his hands on the
steering wheel and to steer himself.
If you do not steer yourself or if you take your hands off the steering wheel for a prolonged
period of time, the system will first alert you
with a visual warning. A steering wheel sym-
bol appears in the multifunction display. If youhave still not started to steer and have not
taken hold of the steering wheel after five
seconds at the latest, a warning tone also
sounds to remind you to take control of the
vehicle. Steering Assist and Stop&Go Pilot
switch to passive mode. DISTRONIC PLUS
remains active.

Suspension setting General notes
The Adaptive Damping System automatically
controls the calibration of the dampers.
The damping is tuned individually to each
wheel and depends on:
R your driving style, e.g. sporty
R the road surface condition, e.g. bumps
R your individual selection, i.e. sport or com-
fort
Your selection remains stored even if you
remove the key from the ignition lock. Sport mode
In the "Sport" and "Sport Plus" drive pro-
grams, the firmer suspension setting ensures even better contact with the road. Select this
mode when employing a sporty driving style,
e.g. on winding country roads.
X Vehicles with automatic transmission:
select the Sor S+ drive program with the
AGILITY SELECT switch (Y page 197).

The vehicle is lowered by 15 mm compared to the normal level.
Comfort mode
In the "Eco" and "Comfort" drive programs,
the driving characteristics of your vehicle are
more comfortable. Therefore, select this
mode if you prefer a more comfortable driving
style. Select Comfort mode also when driving
fast on straight roads, e.g. on straight
stretches of motorway.
X Vehicles with automatic transmission:
select the Eor Cdrive program with the
AGILITY SELECT switch (Y page 197).

The vehicle is raised to the normal level.
When driving at speeds above 125 km/h, the
vehicle is automatically lowered by 15 mm in the Eand Cdrive programs. When driving at
speeds below 80 km/h, the vehicle is raised
again. 4MATIC (permanent all-wheel drive)
4MATIC ensures that all four wheels are per-
manently driven. Together with ESP ®
, it
improves the traction of your vehicle when-
ever a drive wheel spins due to insufficient
grip.
If you fail to adapt your driving style, 4MATIC
can neither reduce the risk of an accident nor Driving systems
