Air conditioning functions in detailSwitching system on/off
Switching on
Press any key, except▷Heated rear window.▷Seat heating
Switching off
In the lowest setting, press the left of
the button.
Temperature Turn the wheel to select the de‐
sired temperature.
The automatic air conditioning sets this tem‐ perature as quickly as possible, using higher
cooling or heating power if necessary. The
temperature is then maintained.
Avoid switching between different temperature
settings in rapid succession. The automatic air
conditioning will not then have sufficient time
to establish the temperature selected.
Cooling function
The interior can only be cooled when the en‐
gine is running.
Press the button.
Air is cooled and dried, then reheated
to suit the temperature setting.
Depending on weather conditions, the wind‐
screen and side windows may mist over mo‐
mentarily when the engine is started.
The cooling function is switched on automati‐
cally in the AUTO program.
When using the automatic air conditioning,
condensation water, see page 165, develops
that exits underneath the vehicle.
Maximum cooling effect Press the button.
System is set to lowest temperature,
optimum air flow and recirculated-air mode.
The air flows from the outlets for the upper
body area. Therefore open the ventilation vents.
The function is available through an outside
temperature of approximately 0 ℃/32 ℉ and
with the engine running.
The air flow can be adapted when the program
is active.
AUTO program Press the button.
The air flow, air distribution and tem‐
perature are automatically regulated.
Depending on the selected temperature, inten‐
sity AUTO program and external influences,
the air is directed towards the windscreen, side
windows, upper body, and into the footwell.
The cooling function, see page 145, is
switched on automatically in the AUTO pro‐
gram.
A condensation sensor also controls the pro‐
gram so that condensation is avoided as much
as possible.
Intensity of AUTO program
When AUTO program is switched on, auto‐
matic control of the intensity can be changed.
Pressing the button on the left or right
reduces or increases intensity.
The selected intensity is shown on the display
for automatic air conditioning.Seite 145ClimateControls145

A vanity mirror is situated in the sun visor be‐
hind a cover. The mirror light switches on
when the cover is opened.

Lighter WARNING
Touching the hot heating element or the
hot fitting of the cigarette lighter can cause
burns. Flammable materials can catch fire if
the lighter falls down or is held against corre‐
sponding objects. Danger of fire and injury.
Grip the cigarette lighter by the handle. Make
sure that children cannot use the lighter and
burn themselves, for example by taking the re‐ mote control with you when leaving the vehi‐
cle.◀
ATTENTION
If metallic objects fall into the socket,
they can cause a short circuit. Danger of dam‐
age to property. After using the socket, put the
lighter or socket cover back on.◀
The cigarette lighter is located next to the ash‐
tray.
Press in the cigarette lighter.
The cigarette lighter can be re‐
moved when it pops back out.

Applying the brakes fully is the most effective
way of braking in situations in which this is
necessary.
The vehicle can be steered. Any obstacles can
be avoided with steering wheel movements
that are as calm as possible.
A pulsing of the brake pedal shows that ABS is
regulating.
In certain braking situations, the perforated
brake disks can cause functional noise. How‐
ever, this has no effect on the efficiency and
operational safety of the brakes.
Objects in the range of movement of
the pedals and in the footwell
WARNING
Objects in the driver's footwell can re‐
strict the pedal travel, or block a pedal that has
been pressed. Danger of accidents. Stow
items in the vehicle so that they are secure and
cannot get into the driver's footwell. Only use
floor mats that have been categorised as ap‐
propriate for the vehicle and that can be fas‐
tened accordingly. Do not use any loose floor
mats, and do not place several floor mats on
top of one another. Make sure that there is suf‐
ficient space for the pedals. Ensure that the
floor mats are securely reattached after having
been removed, for example for cleaning.◀
Wet roads
In damp weather, if road grit has been spread
or there is heavy rain, apply the brakes lightly
every few kilometres/miles.
In doing so, do not obstruct other road users.
The resulting heat dries the brake discs and
pads.
The braking force will be available immediately
if needed.Downhill gradients
WARNING
Even slight, continuous pressure on the
brake pedal can cause overheating, brake pad
wear or even brake system failure. Danger of
accidents. Avoid excessive loads on the
brake.◀
WARNING
When idling or with the engine switched
off, safety-relevant functions are restricted or
no longer available, for example the braking ef‐
fect of the engine or power assistance for the
braking force and steering. Danger of acci‐
dents. Do not drive at idle speed or with the
engine switched off.◀
When driving on long or steep downhill
stretches, use the gear in which the least brak‐
ing is required. Otherwise the brake system
can overheat and braking action is reduced.
Manual gearbox:
The braking effect can be additionally in‐
creased by shifting down, even into first gear, if
applicable.
M double clutch transmission:
The braking action of the engine can be boos‐
ted further by shifting down in sequential
mode, see page 75.
Corrosion of the brake disc Corrosion of the brake discs and contamina‐
tion of the brake pads increase with the
following circumstances:▷Low mileage.▷Extended periods when the vehicle is not
used.▷Infrequent use of the brakes.
Corrosion occurs when the minimum pressure
that must be exerted by the pads during brake
applications to clean the discs is not reached.

Avoid high engine speeds
Basic principle: driving at low engine speeds
reduces fuel consumption and wear.
Use 1st gear to drive off. As from 2nd gear, ac‐
celerate quickly. Avoid high engine speeds and
shift up quickly.
Shift into the highest possible gear when you
have reached the desired speed and drive at a
constant speed with the lowest possible en‐
gine speed.
Pay attention to the shift point indicator in the
vehicle, if fitted, see page 88.
Using overrun mode When approaching a red traffic light, take your
foot off the accelerator and allow the vehicle to
roll.
On downward stretches, take your foot off the
accelerator and allow the vehicle to roll.
The fuel supply is interrupted when coasting.
Switching off engine if
stopping for a relatively long
time
When you stop the vehicle for longer periods,
for example at traffic lights, railway crossings
or in traffic jams, switch off the engine.
Auto Start Stop function
The Auto Start Stop function of your vehicle
shuts off the engine automatically during a
stop.
If the engine is switched off and then started
again, the fuel consumption and emissions are
reduced compared with a permanently running
engine. Savings can be made just by stopping
the engine for a few seconds.
Fuel consumption also depends on other fac‐
tors, such as driving style, road condition,maintenance or environmental factors, for ex‐
ample.
Switching off functions that
are not necessary at the moment
Functions such as seat heating or heated rear
window require a great deal of energy and re‐
duce the range, especially in city traffic and
stop-and-go traffic.
Switch these functions off if they are not re‐
quired.
Having the maintenance
done
Have the vehicle serviced regularly to achieve
optimal economy and lifetime. Have mainte‐
nance carried out by a Service Partner or a
qualified specialist workshop.

tem, see page 191.Seite 169Saving fuelDriving hints169
