Important safety notes
If you fail to adapt your driving style or if you are
inattentive, thedriving safet ysystems can nei-
ther reduce th eris kof an acciden tno roverride
th elaws of physics .Drivin gsafet ysystems are
merely aids designed to assist driving .You are
responsible for maintainin gth edistanc eto th e
vehicl ein front, for vehicl espeed, for braking in
goo dtime, and for staying in lane. Always adapt
your driving style to suit th eprevailing road and
weather condition sand maintai n asafedistanc e
from th evehicl ein front. Drive carefully.
The driving safet ysystems describe donly wor k
as effectivel yas possible when there is ade-
quat econtact between th etires and th eroad
surface. Pay particular attention to th einforma-
tion regarding tires ,recommended minimum
tire tread depths etc. in th e"Wheels and tires "
section (
Ypage 360).
In wintr ydriving conditions, always use winte r
tires (M+ Stires )and if necessary, snow chains.
Only in this way will the driving safety systems
described in this section work as effectively as
possible.
ABS (Anti-lock Braking System)
General information
ABS regulates brake pressure in such a way that
the wheels do not lock when you brake. This
allows you to continue steering the vehicle when
braking.
The ! ABS warning lamp in the instrument
cluster lights up when the ignition is switched
on. It goes out when the engine is running.
ABS works from a speed of about 5 mph
(8 km/h), regardless of road-surface conditions.
ABS works on slippery surfaces, even when you
only brake gently.
Important safety notes
iObserve the "Important safety notes" sec-
tion (Ypage 68).
GWARNING
If ABS is faulty, the wheels could lock when
braking. The steerability and braking charac-
teristics may be severely impaired. Addition-
ally, further driving safety systems are deac-
tivated. There is an increased danger of skid-
ding and accidents.
Drive on carefully. Have ABS checked imme-
diately at a qualified specialist workshop.
When ABS is malfunctioning, other systems,
including driving safety systems, will also
become inoperative. Observe the information
on the ABS warning lamp (
Ypage 289) and dis-
play messages which may be shown in the
instrument cluster (
Ypage 256).
Braking
XIf ABS intervenes: continue to depress the
brake pedal vigorously until the braking sit-
uation is over.
XTo make a full brake application: depress
the brake pedal with full force.
If ABS intervenes when braking, you will feel a
pulsing in the brake pedal.
The pulsating brake pedal can be an indication
of hazardous road conditions, and functions as a reminder to take extra care while driving.
BAS (Brake Assist System)
General information
BAS operates in emergency braking situations.
If you depress the brake pedal quickly, BAS
automatically boosts the braking force, thus
shortening the stopping distance.
Important safety notes
iObserve the "Important safety notes" sec-
tion (Ypage 68).
GWARNING
If BAS is malfunctioning, the braking distance
in an emergency braking situation is
increased. There is a risk of an accident.
In an emergency braking situation, depress
the brake pedal with full force. ABS prevents
the wheels from locking.
68Driving safety systems
Safety

This steering assistance is provided in particular
if:
Rboth right wheels or both left wheels are on awet or slippery road surface when you brake.
Rthe vehicle starts to skid.
Important safety notes
iObserve the "Important safety notes" sec-
tion (Ypage 68).
No steering support is provided from STEER
CONTROL, if:
RESP®is deactivated
RESP®is malfunctioning.
Rthe lighting is faulty.
If ESP®is malfunctioning, you will be assisted
further by the electrical power steering.
Protection against theft
Immobilizer
The immobilizer prevents your vehicle from
being started without the correct SmartKey.
XTo activate with the SmartKey: remove the
SmartKey from the ignition lock.
XTo activate with KEYLESS-GO start-func-
tion or KEYLESS-GO: switch the ignition off
and open the driver's door.
XTo deactivate: switch on the ignition.
When leaving the vehicle, always take the
SmartKey with you and lock the vehicle. Anyone
can start the engine if a valid SmartKey has been
left inside the vehicle.
iThe immobilizer is always deactivated when
you start the engine.
In the event that the engine cannot be started
(yet the vehicle's battery is charged), the sys- tem is not operational. Contact an authorized
Mercedes-Benz Center or call
1-800-FOR-MERCedes (in the USA) or
1-800-387-0100 (in Canada).
ATA (anti-theft alarm system)
XTo arm: lock the vehicle with the SmartKey or
KEYLESS-GO.
Indicator lamp :flashes. The alarm system
is armed after approximately 10 seconds.
XTo disarm: unlock the vehicle with the Smart-
Key or KEYLESS-GO.
or
XInsert the SmartKey into the ignition lock.
A visual and audible alarm is triggered if the
alarm system is armed and you open:
Ra door
Rthe vehicle with the mechanical key
Rthe trunk lid
Rthe hood
XTo turn the alarm off with the SmartKey:
press the %or& button on the Smart-
Key.
The alarm is switched off.
or
XVehicles with KEYLESS-GO start-function
or KEYLESS-GO: remove the Start/Stop but-
ton from the ignition lock (
Ypage 146).
XInsert the SmartKey into the ignition lock.
The alarm is switched off.
XTo stop the alarm using KEYLESS-GO:
grasp the outside door handle. The SmartKey
must be outside the vehicle.
The alarm is switched off.
or
XPress the Start/Stop button on the dash-
board. The SmartKey must be inside the vehi- cle.
The alarm is switched off.
The alarm is not switched off, even if you close
the open door that triggered it, for example.

perfumed although the
perfume atomizer is acti-
vated.The perfume vial has not been pushed into the holder as far as it will
go.
XSlide the perfume vial into the holder as far as it will go.
The perfume vial is not filled sufficiently.
XPre-filled vials:dispose of the empty vial.

Ionization
Ionization is used to purify the air in the vehicle
interior and attain an improved interior climate.
The ionization of the interior air is odorless and
cannot be perceived directly in the vehicle inte-
rior.
You can switch ionization on or off using the
multimedia system (
Ypage 303).
Ionization can only be operated when the auto-
matic climate control is switched on. The side air
vent on the driver's side must be open.

Transmission positions
BPark position
This prevents the vehicle from rolling
away when stopped.
Only shift the transmission into posi-
tion Pwhen the vehicle is stationary
(
Ypage 156). The parking lock
should not be used as a brake when
parking. Always apply the electronic
parking brake in addition to the park-
ing lock in order to secure the vehi-
cle.
Park position Pis automatically
engaged if:
Ryou switch off the engine using the SmartKey and remove the Smart-
Key
Ryou switch off the engine using thekey or using the Start/Stop button
and open the driver's door or front-
passenger door
Rthe driver's door is opened when
the vehicle is stationary or driving
at very low speed and the trans-
mission is in position Dor R
If the vehicle electronics are malfunc-
tioning, the transmission may be
locked in position P. Have the vehicle
electronics checked immediately at a
qualified specialist workshop.
CReverse gear
Only shift the transmission into posi-
tion Rwhen the vehicle is stationary.
ANeutral
Do not shift the transmission to N
while driving. Otherwise, the auto-
matic transmission could be dam-
aged.
No power is transmitted from the
engine to the drive wheels.
Releasing the brake pedal will allow
you to move the vehicle freely, e.g. to
push it or tow it.
If ESP
®is deactivated or faulty: shift
the transmission to position Nif the
vehicle is in danger of skidding, e.g.
on icy roads.
If you switch the engine off with the
transmission in position Ror D, the
automatic transmission shifts to N
automatically.
!Rolling in neutral Ncan damage
the drive train.
7Drive
The automatic transmission changes
gear automatically. All forward gears
are available.
Driving tips
Changing gear
The automatic transmission shifts to the indi-
vidual gears automatically when it is in trans-
mission position D. This automatic gear shifting
behavior is determined by:
Rthe selected drive program
Rthe position of the accelerator pedal
Rthe road speed
Accelerator pedal position
Your style of driving influences how the auto-
matic transmission shifts gear:
Rlittle throttle: early upshifts
Rmore throttle: late upshifts
Double-clutch function
When shifting down, the double-clutch function
is active regardless of the currently selected
drive program. The double-clutch function
