Important safety notes
GWARNING
Children could become trapped if they adjust
the seats, particularly when unattended.
There is a risk of injury.
When leaving the vehicle, always take the
SmartKey with you and lock the vehicle. Never
leave children unsupervised in the vehicle.
The seats can still be adjusted when there is no
SmartKey in the ignition lock.
GWARNING
If the head restraints are not installed or not
adjusted correctly, they cannot provide pro-
tection as intended. There is an increased risk
of injury in the head and neck area, e.g. in the event of an accident or when braking.

Overview of climate control systems
General notes
Observe the settings recommended on the fol-
lowing pages. The windows could otherwise fog
up.
To prevent the windows from fogging up:
Rswitch off climate control only briefly
Rswitch on air-recirculation mode only briefly
Rswitch on the cooling with air dehumidifica-
tion function
Rswitch on the defrost windshield function
briefly, if required
Climate control regulates the temperature and
the humidity in the vehicle interior and filters
undesirable substances out of the air.
Climate control can only be operated when the
engine is running. Optimum operation is only
achieved with the side windows and roof closed.
The residual heat function can only be activated
or deactivated with the ignition switched off
(
Ypage 125).
iWhen the weather is warm, ventilate the
vehicle for a brief period. This will speed up
the cooling process and the desired interior
temperature will be reached more quickly.
iThe integrated filter filters out most parti-
cles of dust and soot and completely filters
out pollen. It also reduces gaseous pollutants
and odors. A clogged 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. As it
depends on environmental conditions, e.g.
heavy air pollution, the interval may be
shorter than stated in the Maintenance Book- let.
iIt is possible that the residual heat function
may be activated automatically an hour after
the SmartKey is removed. The vehicle is then ventilated for 30 minutes to dry the automatic
climate control.

ECO start/stop function
Introduction
The ECO start/stop function switches the
engine off automatically if the vehicle is stopped
under certain conditions.
The engine starts automatically when the driver
wants to pull away again. The ECO start/stop
function thereby helps you to reduce the fuel
consumption and emissions of your vehicle.
Important safety notes
GWARNING
If the engine is switched off automatically and
you exit the vehicle, the engine is restarted
automatically. The vehicle may begin moving.
There is a risk of accident and injury.
If you wish to exit the vehicle, always turn off
the ignition and secure the vehicle against
rolling away.
General notes
:ECO start/stop display
The ECO start/stop function is activated when-
ever you start the engine using the Smartkey or
the Start/Stop button. If the engine has been switched off automati-
cally by the ECO start/stop function, the
¤
symbol is shown in the multifunction display.
Automatic engine switch-off
If the vehicle is braked to a standstill in Dor N,
the ECO start/stop function switches off the
engine automatically.
The ECO start/stop function is operational
when:
Rthe indicator lamp in the ECO button is lit
green.
Rthe outside temperature is within the range
that is suitable for the system.
Rthe engine is at normal operating tempera-
ture.
Rthe set temperature for the vehicle interior
has been reached.
Rthe battery is sufficiently charged.
Rthe system detects that the windshield is not
fogged up when the air-conditioning system is switched on.
Rthe hood is closed.
Rthe driver's door is closed and the driver's
seat belt is fastened.
iAll of the vehicle's systems remain active
when the engine is stopped automatically.
iThe HOLD function can also be activated if
the engine has been switched off automati-
cally. 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 deac-
tivated.
iThe engine can be switched off automati-
cally a maximum of four times (first stop and
three subsequent stops) in succession.

Driving and parking

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.
Limited braking performance on salt-
treated roads
If you drive on salted roads, a layer of salt resi-
due may form on the brake discs and brake
pads. This can result in a significantly longer
braking distance.
RIn order to prevent any salt build-up, apply the
brakes occasionally while paying attention to
the traffic conditions.
RCarefully depress the brake pedal and the
beginning and end of a journey.
RMaintain a greater distance to the vehicle
ahead.
Servicing the brakes
!The brake fluid level may be too low, if:
Rif the red brake warning lamp lights up in
the instrument cluster and
Ryou hear a warning tone while the engine is
running
Observe additional warning messages in the
multifunction display.
The brake fluid level may be too low due to
brake pad wear or leaking brake lines.
Have the brake system checked immediately.
Consult a qualified specialist workshop to
arrange this.
!Vehicles with 4MATIC: function or per-
formance tests may only be carried out on a 2-
axle dynamometer. If you wish to operate the
vehicle on such a dynamometer, please con-
sult a qualified specialist workshop in
advance. You could otherwise damage the
drive train or the brake system.
!Vehicles with 4MATIC: as the ESP®sys-
tem operates automatically, the engine and
the ignition must be switched off (SmartKey in
position 0or 1in the ignition lock or Start/
Stop button in position 0or 1) while the park- ing brake is being tested on a brake dyna-
mometer.
Braking maneuvers triggered automatically
by ESP
®may seriously damage the brake sys-
tem.
!Vehicles with 4MATIC: as the ESP®sys-
tem operates automatically, the engine and
the ignition system must be switched off
(SmartKey in position 0or 1in the ignition
lock or Start/Stop button in position 0or 1)
when:
Rtesting the parking brake on a brake dyna-
mometer.
Ryou intend to have the vehicle towed with
the front axle raised.
Braking maneuvers triggered automatically
by ESP
®may seriously damage the brake sys-
tem.
All checks and maintenance work on the brake
system must be carried out at a qualified spe-
c

ialist workshop.
Have brake pads installed and brake fluid
replaced at a qualified specialist workshop.
If the brake system has only been subject to
moderate loads, you should test the functional-
ity of your brakes at regular intervals. To do so,
press firmly on the brake pedal when driving at a
high speed. This improves the grip of the brake
pads.
You can find a description of Brake Assist (BAS) on (
Ypage 62) or of BAS PLUS with Cross-Traffic
Assist on (Ypage 62).
The braking characteristics of the vehicle can be
seriously impaired if:
Rbrake pads other than those recommended
are installed
Rthe recommended brake fluid is not used
Safe braking can no longer be guaranteed.
Driving on wet roads
Hydroplaning
If water has accumulated to a certain depth on
the road surface, there is a danger of hydro-
planing occurring, even if:
Ryou drive at low speeds.
Rthe tires have adequate tread depth.
Driving tips149
Driving and parking
Z

For this reason, in the event of heavy rain or in
conditions in which hydroplaning may occur,
you must drive in the following manner:
Rlower your speed.
Ravoid ruts.
Ravoid sudden steering movements.
Rbrake carefully.
Driving on flooded roads
!Do not drive through flooded areas. Check
the depth of any water before driving through
it. Drive slowly through standing water. Oth-
erwise, water may enter the vehicle interior or
the engine compartment. This can damage
the electronic components in the engine or
the automatic transmission. Water can also
be drawn in by the engine's air suction nozzles
and this can cause engine damage.
Winter driving
GWARNING
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.
GDANGER
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.
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 the cruise con-
trol or DISTRONIC PLUS.
If the vehicle threatens to skid or cannot be
stopped when moving at low speed:
XShift 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 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
sui t the p
revailing weather conditions.
You should pay special attention to road condi-
tions when temperatures are around freezing
point.

chains, see (
Ypage 287).
For more information on driving with summer
tires, see (
Ypage 287).
Observe the notes in the "Winter operation" sec-
tion (
