field of vision however the objects appear
smaller and further away in the mirrors. If you
use these mirrors to estimate the distance to
vehicles behind you when changing lane, you
could make a mistake. Risk of accident.
● If possible, use the rear vision mirror to es-
timate di
stances to vehicles behind you.
● Make sure that you do not get your finger
trapped betw
een the mirror and the mirror
base when folding back the mirrors. Risk of
injury! For the sake of the environment
The exterior mirror heating should be switch-
ed off when it i
s no longer needed. Other-
wise, it is an unnecessary fuel waste. » 151

Safety

Driving
If the system is deactivated or if it has any
f au
lt, the w
arning lamp will remain lit. The
warning lamp will also light up if a fault
should occur in the ABS because the ASR op-
erates in conjunction with the ABS. For fur-
ther information, see ››› page 183.
The lamp provides information about the
disconnection status of the system:*
● It stays lit when the ASR is disconnected
via E
asy Connect.
By means of Easy Connect, the ASR function
is reactivated and the warning lamp switched
off. WARNING
● Remember th at
not even the ASR can defy
the laws of physics. Bear this in mind, partic-
ularly on slippery and wet roads and when
towing a trailer.
● Always adapt your driving style to suit the
condition of the r
oads and the traffic situa-
tion. The greater safety provided by the ASR
should not encourage you to run any risks. CAUTION
● To en s
ure that the ASR works correctly,
identical tyres should be fitted on all four
wheels. Any differences in the rolling radius
of the tyres can cause the system to reduce
engine power when this is not desired. ●
Any modific
ations made to the vehicle (for
example, to the engine, brake system, run-
ning gear or to the combination of wheels
and tyres) may affect the operation of the
ABS and ASR. Connecting/disconnecting ESC and
ASR*
The ESC is switched on automatically when
the engine i
s
started, and only works when
the engine is running and includes the ABS,
EDS and ASR systems.
The ASR and ESC function should only be
switched off in situations in which traction is
insufficient, among others:
● When driving in deep snow or on surfaces
that ar
e not very firm.
● To “free” the vehicle if it gets stuck.
Then switc
h the ASR and ESC function back
on.
Depending on finishes and versions, it is
possible either to disconnect only the ASR or
else activate ESC Sport mode.
ESC in “Sport” mode
Sport mode can be connected via the Easy
Connect ››› page 122 system menu. The ESC
and the traction control system (ASR) have
only a limited ability to stabilise the vehicle. The control lamp
lights up. F
or vehicles
with a driver information system*, the driver
will be shown the electronic stability
control (ESC) option: sport.
Warning! Limited stability.
Disable ESC “Sport” mode
Through the Easy Connect system menu
››› page 122. The warning lamp will switch
off. For vehicles with a driver information sys-
tem*, the driver will be shown the elec-
tronic stability control (ESC)
option: on.
Disable ASR
The Easy Connect system menu is used to
switch off the ASR ››› page 122. The traction
control system will be disabled.
The control lamp lights up. For vehicles
with a driver information system* the driver
will be informed that ASR is disabled.
Activate ASR
The Easy Connect system menu ››› page 122
is used to switch on the ASR. The traction
control system will be enabled.

Operation
WARNING
Observe the safety warnings ››› in Selector
lev er po
sitions on page 189.
● Never allow the brake to rub and do not use
the brake ped
al too often or for long periods.
Constant braking causes overheating in the
brakes. This could significantly reduce brak-
ing power, increase braking distance or even
result in the total failure of the brake system.
● To avoid rolling back on gradients always
hold the
vehicle with the footbrake or hand-
brake if you have to stop. CAUTION
● If y
ou stop the vehicle on a gradient, do not
attempt to stop it from rolling by depressing
the accelerator when a gear has been selec-
ted. This could cause overheating and dam-
age the automatic gearbox. Apply the hand-
brake firmly or press the brake pedal in order
to prevent the vehicle from rolling back.
● If you allow the car to roll with the selector
lever in po
sition N with the engine switched
off, the automatic gearbox will be damaged
as it will not be lubricated.
● In certain driving situations or traffic condi-
tions, suc
h as frequently starting, prolonged
“creeping” of the vehicle or traffic jams with
continuous stoppages, the gearbox could overheat causing damage! If the warning
lamp
lights up, stop the vehicle as soon as
possible and wait for the gearbox to cool
››› page 194. Kick-down feature
The kick-down feature allows maximum ac-
cel
er
ation to be reached.
When the accelerator pedal is pressed right
down past the point of resistance at full throt-
tle, the gearbox will shift down to a lower
gear, depending on road speed and engine
speed. The upshift to the next higher gear is
delayed until the engine reaches maximum
rpm. WARNING
Please note that if the road surface is slip-
pery or w
et, the kick-down feature could
cause the driving wheels to spin, which could
result in skidding. Launch control program
3 Valid for vehicles: with Launch-Control/6-Speed
D SG w
ith diesel engines superior to 125 kW and pet-
rol engines superior to 140 kW.
The Launch control programme enables maxi-
mum acceleration.
Important: the engine must have reached op-
erating temperature and the steering wheel
must not be turned.
The engine speed for launch-control is differ-
ent on petrol and diesel engines. To use the
launch-control you must disconnect the anti-
slip regulation (ASR) through the Easy Con-
nect system menu ›››

lamp will stay switched on or will flash
slowly depending on whether or not the vehi-
cle has a driver information system*.
On vehicles with the driver information sys-
tem, the ESC lamp lights up permanently and

distance.
● Do not use the cruise control in heavy traf-
fic, if the dis
tance from the vehicle in front is
insufficient, on steep roads, with several
bends or in slippery circumstances (snow,
ice, rain or loose gravel), or on flooded roads.
● Never use the CCS when driving off-road or
on unpav
ed roads.
● Always adapt your speed and the distance
to the v
ehicles ahead in line with visibility,
weather conditions, the condition of the road
and the traffic situation.
● To avoid unexpected operation of the cruise
contro
l system, turn it off every time you fin-
ish using it.
● It is dangerous to use a set speed which is
too high for the pr
evailing road, traffic or
weather conditions.
● When travelling down hills, the CCS cannot
maintain a c
onstant speed. The vehicle tends
to accelerate under its own weight. Select a
lower gear or use the foot brake to slow the
vehicle. WARNING

Changing gear in CCS mode
The CCS decelerates as soon as the clutch
pedal is pressed, intervening again automati-
cally after a gear is engaged.
Travelling down hills with the CCS
When travelling down hills the CCS cannot
maintain a constant speed. Slow the vehicle
down using the brake pedal and reduce
gears if required.

Operation
The ACC is operational as of the 2nd gear
(m anual
g
earbox).
ACC: engine speed
The message for the driver is displayed if,
when the ACC accelerates or brakes, the driv-
er does not shift up or down a gear in time,
which means exceeding or not reaching the
permissible engine speed. The ACC switches
itself off. A buzzer warning is heard. ACC: clutch pressed
Vehicles with a manual gearbox: pressing the
clutch pedal for longer abandons control
mode. Door open
Vehicles with automatic gearbox: the ACC
cannot be activated with the vehicle station-
ary and the door open. WARNING
There is a danger of rear collision when the
minimum dis t
ance to the vehicle in front is
exceeded and the speed difference between
both vehicles is so great that a speed reduc-
tion by the ACC will not suffice. In this case
the brake pedal should be applied immedi-
ately.
● The ACC may not be able to detect all situa-
tions pr
operly.
● “Stepping” on the accelerator may cause
the ACC
not to intervene in braking. Driver braking will have priority over intervention by
the speed c
ontr
ol or adaptive cruise control.
● Always be ready to use the brakes!
● Observe country-specific provisions gov-
erning ob
ligatory minimum distances be-
tween vehicles.
● It is dangerous to activate control and re-
sume the progr
ammed speed if the road, traf-
fic or weather conditions do not permit this.
Risk of accident! Note
● The pr ogrammed s
peed is erased once the
ignition or the ACC are switched off.
● When the traction control system (ASR) is
deactivat
ed during acceleration or else the
ESC is activated in Sport* Mode
( ››› page 122), the ACC switches off automati-
cally.
● In vehicles with the Start-Stop system, the
engine swit
ches off automatically during the
ACC stopping phase and restarts automatical-
ly to begin driving. Function for preventing overtaking in

To avoid overtaking while driving in an inside
lane the system will gently brake, and in ac-
cordance with the speed will prevent the car
from overtaking. The driver can override this
function at any time by pressing the accelera-
tor pedal. At low speeds the function is inac-
tive, for greater comfort in a traffic jam or in
city traffic.
