For PRE-SAFE ®
Brake to assist yo uwhend riv-

system must be switched on and operational.
With the hel pofthe rada rsensor system and

WARNING
When the double lock sare activated, the
doors can no longer be opened from the
inside. People in the vehicle can no longer get out, e.g. in hazardous situations. There is a
risk of injury.
Therefore, do not leave any people unsuper-
vised in the vehicle, particularly children ,eld-
erly people or people in need of special assis-
tance. Do not activate the double lock when
people are in the vehicle.
If the vehicle has been locked from the out-
side, the double lock function is activated as
standard. It is then not possible to open the
doors from inside the vehicle. You can deac-
tivat ethe double lock function by deactivat-
ing the interior motion sensor (Y page 91).
The doors can then be opened from the inside after the vehicle has been locked from the
outside.
The anti-theft alarm system is triggered if thedoor is opened from the inside. Switc hoff the

WARNING
If children are left unsupervised in the vehicle, they could:
R open doors, thereby endangering other per-
sons or road users
R get out and be struck by oncoming traffic
R operate vehicle equipment and become
trapped, for example
In addition ,the children could also set the
vehicle in motion, for example, if they:
R release the parkin gbrake
R shift the automatic transmission out of park
position Porshift manual transmission into
neutral
R start the engine
There is arisk of an acciden tand injury.
When leaving the vehicle, always tak ethe key
with you and lock the vehicle. Never leave
children and animals unattended in the vehi-
cle. Keep the keys out of the reach of children. G
WARNING
If you attach heavy or large objects to the key, the key could be unintentionally turned in the
ignition lock .This could cause the engin eto
be switched off. There is arisk of an accident.
Do not attach any heavy or large objects to the
key. Remove any bulky keyrings before insert-
ing the key int othe ignition lock.
! Keep the key away from strong magnetic
fields. Otherwise, the remot econtro lfunc-
tion could be affected.
Stron gmagnetic fields can occur in the
vicinity of powerful electrical installations.
Do not keep the key: R with electronic devices ,e.g. am obile
phone or another key
R with metallic objects, e.g. coin sormetal

In certain drivin gand drivin gsafet ysystems,
the sensors adjust automatically while acer-
tain distance is being driven after the vehicle has been delivered or after repairs. Full sys-
tem effectiveness is not reached until the end
of this teach-in process.
Brak epads/linings and discs that are either
new or have been replaced only achieve opti- mum brakin geffec tafter several hundred kil-
ometres of driving. Compensate for the
reduced brakin geffec tbya pplying greater

If you treat the engin ewith sufficient care
from the very start ,you will be rewarded with
excellent performanc efor the remainder of
the engine's life.
R Driv eatv arying road speeds and engine
speeds for the first 1,50 0km.
R Avoid overstraining the vehicle during this
period, e.g. drivin gatfull throttle.
R Change gear in good time, before the rev
counter needle is Ôof the way to the red
area of the rev counter. R
Do not shift down agear manually in order
to brake.
R Vehicles with automatic transmission:
try to avoid depressin gthe accelerator
pedal beyond the point of resistance (kick-
down).
Additional running-in notes for AMG vehicles:
R Do not drive at speeds above 140 km/ hfor
the first 1,500 km.
R Only allow the engine to reach amaximum
engine speed of 4,500 rpm briefly.
After 1,500 km, you may graduall yaccelerate
the vehicle to full road and engine speeds.
i You should also observe these notes on
running-in if the engine or parts of the drive
train on your vehicle have been replaced. AMG vehicles with self-locking rear
axle differential
Your vehicle is equipped with aself-locking
differential on the rear axle.
Change the oil to improve protection of the
rear axle differential:
R after arunning-in period of 3,000 km
R every 50,000 km or 3years
These oil changes prolong the service life of
the differential. Have the oil change carried
out at aqualified specialist workshop. Driving

lever up :to the pressure point for a
higher speed or down ;for alower speed.
or
X Keep the cruise control lever pressed to the
pressure point until the desired speed is
set. Press the cruise control lever up :for
ah igher speed or down ;for alower

Switching SPEEDTRONIC to passive
If you depress the accelerator pedal beyond
the pressure point (kickdown), SPEED-
TRONIC is switched to passive mode. The fol-
lowing message appears in the multifunction
display: SPEEDTRONIC passive SPEEDTRONIC passive.
You can then exceed the stored speed.
SPEEDTRONIC is activated againify ou:
R drive slower than the stored speed without

R set anew speed or
R call up the last speed stored again

Deactivating variable SPEEDTRONIC
It is not possible to deactivate variable

X Briefly press the cruise control lever for-
wards :.
or X Briefly press the cruise control lever in the

i The last speed stored is cleared when you
switch off the engine.
Permanent SPEEDTRONIC You can use the on-board computer to limit
the speed permanently to
avalue between
160 km/h(e.g. for driving on winter tyres) and the maximum speed (Y page 292).
Shortly before the stored speed is reached, it appears in the multifunction display.
Permanent SPEEDTRONIC remains active,
even if variableS PEEDTRONIC is deactivated.
You cannot exceed the stored limit speed,
even if you depress the accelerator pedal
beyond the pressure point (kickdown). DISTRONIC PLUS

tance to the vehicle detected in front.V ehi-
cles are detected with the aid of the radar
sensor system. DISTRONIC PLUS brakes

If you fai ltoadapt you rdriving style, 4MATIC
can neither reduce the risk of an accident nor override the laws of physics. 4MATIC cannot
take account of road ,weather and traffic con-
ditions. 4MATIC is only an aid. You are
responsibl efor the distance to the vehicle in
front, for vehicle speed, for braking in good
time, and for staying in lane.
If ad rive wheel spins due to insufficient grip:
R whe npulling away,o nly depress the accel-
erato rpedal as far as is necessary.
R accelerate les swhend riving.
! Never tow the vehicle with one axle
raised. Thi smay damage the transfer case.
Damag eofthis sort is not covered by the
Mercedes-Benz implied warranty. All
wheels must remain eithe ronthe ground or
be fully raised. Observe the instructions for towing the vehicle with allw heels in full
contact with the ground.
i In wintry driving conditions, the maximum
effect of 4MATIC can only be achieved if you use winter tyres
(M+S tyres), with snow
chains if necessary.
4MATIC ensures that allf our wheels are per-
manently driven. Together with ESP ®
