Useful information
i This Operator's Manual describes all
models and all standard and optional
equipment of your vehicle available at the
time of publication of the Operator's
Manual. Country-specific differences are
possible. Please note that your vehicle may
not be equipped with all features
described. This also applies to safety-
related systems and functions.

WARNING
Observe the settings recommended on the
following pages. The windows could
otherwise fog up. This could preven tyou from
observing the traffic conditions, thereby
causing an accident. G
WARNING
Severe conditions (e.g. strong air pollution)
may require replacement of the filter before
its scheduled replacement interval. Aclogged
filter will reduce the air volume to the interior
and the windows could fog up, impairing
visibility and endangering you and others.
Have a clogged filter replaced as soon as
possible at a qualified specialist workshop.
Climate control regulates the temperature
and the humidity in the vehicle interior and
filters undesirable substances out of the air.
Climate control is only operational when the
engine is running. The system only works
optimally when the side windows and the roof
are closed.
The residual heat function can only be
activated or deactivated with the ignition
switched off (Y page 129). i
Ventilate the vehicle for a brief period
during warm weather .This will speed up the
cooling process and the desired vehicle
interior temperature will be reached more
quickly.
i The integrated filter can filter out most
particles of dust, and completely filters out
pollen. Aclogged filter reduces the amount
of air supplied to the vehicle interior .For
this reason, you should always observe the
interval for replacing the filter, which is
specified in the Maintenance Booklet.
Since the replacement interval depends on
environmental conditions, e.g. heavy air
pollution, the interval may be shorter than
stated in the Maintenance Booklet. 120

Automatic engine switch-off
Method of operation
The ECO start/stop function is operational
and the
000Esymbol is displayed in the
multifunction display, if:
R the indicator lamp in th eECO butto nis lit
green.
R the outside temperature is within the
comfort range.
R the engine is at normal operating
temperature.
R the set temperature for the vehicle interior
has been reached.
R the battery is sufficiently charged.
R the system detects that the windshield is
not fogged up when the air-conditioning
system is switched on
R the hood is closed.
R the driver's door is closed and the driver's
seat belt is fastened.
If conditions for automatic engine switch-off
have not been fulfilled, the 000Esymbol will
not be shown.
i All vehicles (apart from AMG
vehicles): automatic engine switch-off can
take place a maximum of four times
consecutively (initial stop then repeated
three times). The automatic engine switch-
off is then available againa fter the000E
symbol appears in the multifunction
display.
i AMG vehicles: times which the engine
can be automatically switched off.
i You can still activate the HOLD function
whe nthe vehicle is stationary, even if the
engine has been switched off
automatically. It is then not necessary to
continue applying the brakes during the
automatic stop phase. When you depress
the accelerator pedal, the engine starts
automatically and the braking effect of the
HOLD function is deactivated. Depress the accelerator pedal carefully, as the engine
must be started first.
Vehicles with manual transmission The ECO start/stop function switches off the
engine automatically at low speeds.
X
Brake the vehicle until it comes to a
standstill.
X Engage neutral N(Ypage 144) (follow
gearshift instruction 0003to engage neutral
N, if necessary).
X Release the clutch pedal.
The engine is switched off automatically.
Vehicles with automatic transmission
If the vehicle is braked to a standstill in Dor
N, the ECO start/stop function switches off
the engine automatically.
i If you shift the transmission from Rto D,
the ECO start/stop function is available
again once the 000Esymbol reappears in
the multifunction display.
Automatic engine start Method of operation
The engine starts automatically if:
R
you switch off the ECO start/stop function
by pressing the ECO button.
R you engage reverse gear R.
R you switch to drive program Sor M(AMG
vehicles).
R you unfasten your seat belt or open the
driver's door. Driving
141Driving and parking Z

In addition to driving style, the consumption
is affected by many other factors, such as:
R
Load
R Tire pressure
R Cold start
R Choice of route
R the use of electrical consumers
These factors are not included in the ECO
display.
The evaluationofy our driving style takes the
following three categories into consideration:
Acceleration (evaluation of all
acceleration processes) The bar fills up: The bar empties:
Moderate
acceleration,
especially at higher
speeds Sporty acceleration
Constant (assessment of driving
behavior at all times) The bar fills up: The bar empties:
Constant speed and
avoidance of
unnecessary
acceleration and
deceleration Fluctuations in
speed
Coasting (assessment of all deceleration
processes)
The bar fills up: The bar empties:
Anticipatory driving,
keeping your
distance and early
release of the
accelerator: the
vehicle can coast
without use of the
brakes Frequent braking i
An economical driving style involves
driving with 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
(vehicles with automatic transmission).
i On long journeys at a constant speed, e.g.
on the freeway, only the bar for "smooth
driving" will change.
i The ECO display summarizes the driving
characteristics from the start of the journey
to its completion .Therefore, there are
dynamic changes in the bars at the start of
a journey. During a prolonged driving time,
these changes are smaller. For dynamic
changes, perform a manual reset.

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
braking on a slippery road surface.
Downhill gradients !
On long, steep gradients, you must
reduce the load on the brakes. In order to
use engine braking effect, restrict the shift
range in good time. This helps you to avoid
overheating the brakes and wearing them
out excessively.
When making use of the engine braking
effect, it is possible that a drive wheel may
not turn for some time, e.g. in the case of
suddenly changing or slippery road surface 160

traffi
cbecause conditions do not allow safe
driving at a constant speed.
R The use of the cruise control can be
dangerous on slippery roads. Rapid
changes in tire traction can result in wheel
spin and loss of control.
R Deactivate the cruise control when driving
in fog.
The "Resume" function should only be
operated if the driver is fully aware of the
previously set speed and wishes to resume
this particular preset speed. G
WARNING
The cruise control brakes automatically so
that the set speed is not exceeded.
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 shift range
1, 2or 3in good time (Y page 149). By doing
so, you will make use of the braking effec tof
the engine, which relieves the load on the
brake syste mand 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 prolonge dperiod. You can
store any road speed above 20 mph
