If there is no vehicle in front, DISTRONIC
PLUS operates in the same way as cruise
control.
If DISTRONIC PLUS detects that the vehicle in
front has slowed down, it brakes your vehicle.
In this way, the distance you have selected is
maintained.
If DISTRONIC PLUS detects a faster-moving
vehicle in front, it increases the driving speed. However, the vehicle is only accelerated up to
the speed you have stored.
Selecting the drive program
DISTRONIC PLUS supports a sporty driving
style when you have selected the Sor M(AMG
vehicles: S,S+ orM) driving program
(
Ypage 144). Acceleration behind the vehicle
in front or to the set speed is then noticeably
more dynamic. If you have selected the Eor E
+ (AMG vehicles: C) driving program, the vehi-
cle accelerates more gently. This setting is
recommended in stop-and-start traffic.

Changing lanes
If you change to the passing lane, DISTRONIC
PLUS supports you when:
Ryou are driving faster than 45 mph
(70 km/h)
RDISTRONIC PLUS is maintaining the dis-
tance to a vehicle in front
Ryou have switched on the corresponding
turn signal
RDISTRONIC PLUS does not detect a danger
of collision If these conditions are fulfilled, your vehicle is
accelerated. Acceleration will be interrupted
if changing lanes takes too long or if the dis-
tance between your vehicle and the vehicle in
front becomes too small.
iWhen changing lanes, DISTRONIC PLUS
monitors the left lane on left-hand drive
vehicles and the right lane on right-hand
drive vehicles.
Stopping
GWARNING
When leaving the vehicle, even if it is braked
only by DISTRONIC PLUS, it could roll away if:
Rthere is a malfunction in the system or in
the voltage supply.
RDISTRONIC PLUS has been deactivated
with the cruise control lever, e.g. by a vehi-
cle occupant or from outside the vehicle.
Rthe electrical system in the engine com-
partment, the battery or the fuses have
been tampered with.
Rthe battery is disconnected.
Rthe accelerator pedal has been depressed, e.g. by a vehicle occupant.
There is a risk of an accident.
If you wish to exit the vehicle, always turn off
DISTRONIC PLUS and secure the vehicle
against rolling away.
For further information on deactivating
DISTRONIC PLUS (
Ypage 161).
If DISTRONIC PLUS detects that the vehicle in
front is stopping, it brakes your vehicle until it is stationary.
Once your vehicle is stationary, it remains
stationary and you do not need to depress the
brake.
Depending on the specified minimum dis-
tance, your vehicle will come to a standstill at
a sufficient distance behind the vehicle in
front. The specified minimum distance is set
using the control on the cruise control lever.

HOLD function
General notes
The HOLD function can assist the driver in the
following situations:
Rwhen pulling away, especially on steep
slopes
Rwhen maneuvering on steep slopes
Rwhen waiting in traffic
The vehicle is kept stationary without the
driver having to depress the brake pedal.
The braking effect is canceled and the HOLD
function deactivated when you depress the
accelerator pedal to pull away.
Important safety notes
GWARNING
When leaving the vehicle, it can still roll away despite being braked by the HOLD function if:
Rthere is a malfunction in the system or in
the voltage supply.
Rthe HOLD function has been deactivated by
pressing the accelerator pedal or the brake
pedal, e.g. by a vehicle occupant.
Rthe electrical system in the engine com-
partment, the battery or the fuses have
been tampered with.
Rthe battery is disconnected
There is a risk of an accident.
If you wish to exit the vehicle, always turn off the HOLD function and secure the vehicle
against rolling away.
!If DISTRONIC PLUS or the HOLD function
is activated, the vehicle brakes automati-
cally in certain situations. To prevent damage to the vehicle, deacti-
vate DISTRONIC PLUS and the HOLD func-
tion in the following or other similar situa-
tions:
Rwhen towing the vehicle
Rin the car wash

iNot all mobile phones available on the
market are equally suitable. You can obtain

Procedure and general information
Searching for and authorizing (connect-
ing) a mobile phone
Before using your mobile phone with Audio
20/COMAND for the first time, you will need
to search (
Ypage 229) for the phone and
then authorize it (
Ypage 229). Depending on
the mobile phone, authorization either takes
place by means of Secure Simple Pairing or by
entering a passkey. Audio 20/COMAND
automatically makes the system suitable for
your mobile phone available. You can recog-
nize Secure Simple Pairing by a code which is displayed in Audio 20/COMAND and on the
mobile phone. You can recognize the passkey
system by the fact that you have to enter a
code on the mobile phone and in Audio 20/
COMAND. The mobile phone is always con-
nected automatically after authorization.
If Audio 20/COMAND does not detect your
mobile phone, this may be due to particular
security settings on your mobile phone. You
can also start the search procedure and
authorization on the mobile phone
(
Ypage 230).

and connecting Bluetooth
®-capable mobile
phones can be found on the Internet at

!Residue from the tire sealant may come
out of the filler hose after use. This could
cause stains.
Therefore, place the filler hose in the plastic
bag which contained the TIREFIT kit.
HEnvironmental note
Have the used tire sealant bottle disposed of
professionally, e.g. at a qualified specialist
workshop.
If a tire pressure of 180 kPa (1.8 bar/26 psi)
has been attained after five minutes:
XSwitch off the tire inflation compressor.
XUnscrew the filler hose from the valve of
the faulty tire.
XStow the tire sealant bottle and the tire
inflation compressor.
XPull away immediately.
XStop after driving for approximately ten
minutes and check the tire pressure with
the tire inflation compressor.
The tire pressure must now be at least
130 kPa (1.3 bar/19 psi).
GWARNING
If the required tire pressure is not reached
after driving for a short period, the tire is too
badly damaged. The tire sealant cannot repair
the tire in this instance. Damaged tires and a
tire pressure that is too low can significantly
impair the vehicle's braking and driving char-
acteristics. There is a risk of accident.
Do not continue driving. Contact a qualified
specialist workshop.
iIn cases such as the one mentioned
above, contact an authorized Mercedes-
Benz Center. Or call 1-800-FOR-MERCedes
(in the USA) or 1-800-387-0100 (in Can-
ada).
XCorrect the tire pressure if it is still at least
130 kPa (1.3 bar/19 psi). See the Tire and
Loading Information placard on the driver's side B-pillar or the tire pressure table in the
fuel filler flap for values.
XTo increase the tire pressure: switch on
the tire inflation compressor.
XTo reduce the tire pressure: depress
pressure release button Enext to pres-
sure gauge F.
XWhen the tire pressure is correct, unscrew
the filler hose from the valve of the sealed
tire.
XScrew the valve cap onto the tire valve of
the sealed tire.
XPull the tire sealant bottle out of the tire
inflation compressor.
The filler hose remains attached to the tire
sealant bottle.
XDrive to the nearest qualified specialist
workshop and have the tire changed there.
XHave the tire sealant bottle replaced as
soon as possible at a qualified specialist
workshop.
XHave the tire sealant bottle replaced every
four years at a qualified specialist work-
shop.
