While the memory function is making adjust-
ments, make sure that no one has any body
parts in the sweep of the seat. If somebody
becomes trapped, immediately release the
memory function position button. The adjust- ment process is stopped. G
WARNING
Children could become trapped if they acti-
vate the memory function, 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 memory function can be used at any time,
e.g. even when the SmartKey is not in the igni-
tion lock. Storing settings
With the memory function, you can store up to
three different settings, e.g. for three different
people.
The following settings are stored as a single
memory preset:
R seat and backrest position
R driver's side: position of the exterior mirrors
on the driver's and front-passenger sides X
Adjust the seat (Y page 80).
X Adjust the exterior mirror on the driver's side
(Y page 84).
X Briefly press the Mmemory button and then
press preset position button 1,2or 3within
three seconds.
The settings are stored in the selected preset
position. A tone sounds when the settings
have been completed. Calling up a stored setting
X Press and hold the relevant preset position
button 1,2or 3until the seat and exterior
mirrors are in the stored position.

operation of the headlamps varies due to legal
requirements and self-imposed obligations. Setting the exterior lighting

WARNING
When the light switch is set to 0058, the low-
beam headlamps may not be switched on
automatically if there is fog, snow or other
causes of poor visibility due to the weather
conditions such as spray. There is a risk of an
accident.
In such situations, turn the light switch to
0058.
The automatic headlamp feature is only an aid.
The driver is responsible for the vehicle's light-
ing at all times.
The daytime running lamps improve the visibility
of your vehicle during the day. To do this, the
daytime running lamps function must be
switched on using the on-board computer
(Y page 166).
If the drive system is switched on and you turn
the light switch to 0060or0058, the manual
settings take precedence over the daytime run- ning lamps.
Low-beam headlamps Even if the light sensor does not detect that it isdark, the parking lamps and low-beam head-
lamps come on when the ignition is switched on
and the light switch is set to the 0058position.

Important safety notes
Xenon bulbs: G
DANGER
Xenon bulbs carry a high voltage. You can get an electric shock if you remove the cover of
the Xenon bulb and touch the electrical con-
tacts. There is a risk of fatal injury.
Never touch the parts or the electrical con-
tacts of the Xenon bulb. Always have work on
the Xenon bulbs carried out at a qualified spe-
cialist workshop.
If your vehicle is equipped with Xenon bulbs, you
can recognize this by the following: the cone of light from the Xenon bulbs moves from the top
to the bottom and back again when you start the
drive system. For this to be observed, the lights must be switched on before the drive system is
started.
Headlamps and lights are an important aspect of
vehicle safety. You must therefore make sure
that these function correctly at all times. Have
the headlamp setting checked regularly.
Other bulbs: G
WARNING
Bulbs, lamps and connectors can get very hot when operating. If you change a bulb, you
could burn yourself on these components.
There is a risk of injury.
Allow these components to cool down before changing a bulb.
Do not use a bulb if it has been dropped or if its glass tube has been scratched.
The bulb may explode if
R you touch it
R it is hot
R you drop it
R you scratch it
Use bulbs only in closed lamps that have been
designed for this purpose. Only install spare
bulbs of the same type and the specified volt-
age.
Marks on the glass tube reduce the service life
of the bulbs. Do not touch the glass tube with
your bare hands. If necessary, clean the glass 90

tube when cold with alcohol or spirit and rub it
off with a lint-free cloth.
Protect bulbs from moisture during operation.
Do not allow bulbs to come into contact with
liquids.
Besides the Xenon bulbs, there are other bulbs
that you cannot replace yourself. Replace only
the bulbs listed (Y page 91). Have the bulbs
that you cannot change yourself replaced at a
qualified specialist workshop.
If you require assistance replacing bulbs, con-
sult a qualified specialist workshop.
If the new bulb still does not light up, consult a
qualified specialist workshop.

R Set the temperature to 72 ‡ (22 †).
R Only use the "Windshield defrosting" function
briefly until the windshield is clear again.
R Only use air-recirculation mode briefly, e.g. if
there are unpleasant outside odors or when in a tunnel. The windows could otherwise fog up,
since no fresh air is drawn into the vehicle in
air-recirculation mode.
R Use the ZONE function to adopt the temper-
ature settings on the driver's side for the
front-passenger side as well. The indicator
lamp in the 00D6button goes out.
R If you change the settings of the climate con-
trol system, the climate status display
appears for approximately three seconds at
the bottom of the screen in the multimedia
system display; see separate operating
instructions. You will see the current settings
of the various climate control functions.
You can choose between various drive programs
with the program selector button (Y page 114).
If you have selected drive program E+:
R the cooling output is reduced when cooling

WARNING
Very hot or very cold air can flow from the air vents. This could result in burns or frostbite in the immediate vicinity of the air vents. There
is a risk of injury.
Make sure that all vehicle occupants always
maintain a sufficient distance to the air out-
lets. If necessary, redirect the airflow to
another area of the vehicle interior.
In order to ensure the direct flow of fresh air
through the air vents into the vehicle interior,
please observe the following notes:
R keep the air inlet between the windshield and
the hood free of blockages, such as ice, snow or leaves.
R never cover the air vents or air intake grilles in
the vehicle interior.

and even driving style and results in a reduc-

(110 km/h).

Manually adjustable recuperation 0043
Left-hand steering wheel paddle shifter -
0044 Right-hand steering wheel paddle shifter +
You can increase or reduce recuperation in over- run mode using the steering wheel paddle shift-
ers. When you remove your foot from the accel-
erator pedal, recuperation occurs. The electric
motor is then used as a alternator and energy is recovered while driving. The recuperated elec-
trical energy is stored in the high-voltage bat-
tery. A higher energy recuperation level means
that the vehicle is braked more powerfully.
If necessary, counteract the reduced regenera-
tive braking effect by applying the brake your-
self.

tem (Y page 64). X
To decrease recuperation: pull right-hand
steering wheel paddle shifter 0044.
X To increase recuperation: pull left-hand
steering wheel paddle shifter 0043.
The various recuperation levels are shown in the
transmission position display once Dhas been
selected (Y page 112).
The following recuperation levels are available in
overrun mode:
R no recuperation (D +

R moderate recuperation ( D)
R high recuperation ( D-

R recuperation depending on the traffic situa-
tion (D AUTO

You can see the intensity of recuperation in
overrun mode by reading the recuperation per-
formance value shown in the power display
(Y page 153).
