ion length. The entire base of the child
restraint system must always rest on the seat
cushion of the front-passenger seat. The
backrest of the child restraint system must lie
as flat as possible against the backrest of the
front-passenger seat. The child restraint sys-
tem must not touch the roof or be subjected
to a load by the head restraint. Adjust the
angle of the seat backrest and the head
restraint position accordingly. Always make
sure that the shoulder belt strap is correctly
routed from the front-passenger seat belt
guide to the shoulder belt guide on the child
restraint system. The shoulder belt strap
must be routed forwards and downwards
from the front-passenger seat belt guide. If
necessary, adjust the front-passenger seat
accordingly.
Always observe the child restraint system
manufacturer's installation and operating
instructions.
Pets in the vehicle
GWARNING
If you leave animals unattended or unsecured
in the vehicle, they could press buttons or
switches, for example.
As a result, they could:
Ractivate vehicle equipment and become
trapped, for example
Ractivate or deactivate systems, thereby
endangering other road users
Unsecured animals could also be flung around
the vehicle in the event of an accident or sud-
den steering or braking, thereby injuring vehi-
cle occupants. There is a risk of an accident
and injury.
Never leave animals unattended in the vehi-
cle. Always secure animals properly during
the journey, e.g. use a suitable animal trans-
port box.

Important safety notes
If you fail to adapt your driving style or if you
are inattentive, the driving safety systems can
neither reduce the risk of an accident nor
override the laws of physics. Driving safety
systems are merely aids designed to assist
driving. You are responsible for maintaining
the distance to the vehicle in front, for vehicle
speed, for braking in good time, and for stay-
ing in lane. Always adapt your driving style to
suit the prevailing road and weather condi-
tions and maintain a safe distance from the
vehicle in front. Drive carefully.
The driving safety systems described only
work as effectively as possible when there is
adequate contact between the tires and the
road surface. Please pay special attention to
the notes on tires, recommended minimum
tire tread depths, etc. (
Ypage 568).
In wintry driving conditions, always use winter
tires (M+S tires) 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)
Gene ral inform ation
ABSregulates brak epressur ein suc h away
that th ewheels do no tloc kwhen you brake.
This allows you to continu esteering th evehi-
cle when braking .
The ! ABSwarning lamp in th einstrumen t
cluste rlights up when th eignition is switched
on .It goes out when th eengin eis running.
AB Sworks from aspee dof about 5mph
(8 km/h), regardless of road-surface condi-
tions. AB Sworks on slippery surfaces, eve n
when you only brak egently.

Braking
XIf ABS intervenes: continueto depress th e

tion of hazardous road condition s,and func-
tion sas areminder to tak eextr acar ewhile

tions. If you depress th ebrak epedal quickly,
BA Sautomatically boosts th ebraking force ,
thus shortening th e stopping distance.

tection measures (PRE-SAFE®) are activa-
ted simultaneously.
XKeep the brake pedal depressed until the
emergency braking situation is over.
ABS prevents the wheels from locking.
BAS PLUS is deactivated and the brakes func-
tion as usual again, if:
Ryou release the brake pedal.
Rthere is no longer a risk of collision.
Rno obstacle is detected in front of your
vehicle.
Ryou depress the accelerator pedal.
Ryou activate kickdown.
ESP®(Electronic Stability Program)
General notes
iObserve the "Important safety notes" sec-
tion (
Ypage 71).
ESP
®monitors driving stability and traction,
i.e. power transmission between the tires and
the road surface.
If ESP
®detects that the vehicle is deviating
from the direction desired by the driver, one
or more wheels are braked to stabilize the
vehicle. The engine output is also modified to
keep the vehicle on the desired course within
physical limits. ESP
®assists the driver when
pulling away on wet or slippery roads. ESP®
can also stabilize the vehicle during braking.
ETS (Electronic Traction System)
iObserve the "Important safety notes" sec-
tion (
Ypage 71).
ETS traction control is part of ESP
®.
ETS brakes the drive wheels individually if
they spin. This enables you to pull away and
accelerate on slippery surfaces, for example
if the road surface is slippery on one side. In
addition, more drive torque is transferred to
the wheel or wheels with traction. ETS remains active when you deactivate
ESP
®.
iMercedes-AMG vehicles:
your vehicle
may be equipped with 20-inch tires on the
rear axle. After changing to 19 inch wheels,
ETS may intervene noticeably earlier during
the first few kilometers. After approx-
imately 10 km ETS will function as usual
again. Information on the dimensions and
types of wheels and tires for your vehicle
can be found in the "Wheel/tire combina-
tions" section (
Ypage 593).
Important safety notes
GWARNING
If ESP
®is malfunctioning, ESP®is unable to
stabilize the vehicle. Additionally, further driv-
ing safety systems are deactivated. This
increases the risk of skidding and an accident.
Drive on carefully. Have ESP
®checked at a
qualified specialist workshop.
When towing the vehicle with the rear axle
raised, observe the notes on ESP®
(Ypage 563).
ESP
®is only deactivated if the åwarning
lamp is lit continuously.
If the ÷ warning lamp and the åwarn-
ing lamp are lit continuously, ESP
®not avail-
able due to a malfunction.
Observe the information on warning lamps
(
Ypage 274) and display messages which
may be shown in the instrument cluster
(
Ypage 240).
iOnly use wheels with the recommended
tire sizes. Only then will ESP®function
properly.
Characteristics of ESP®
General information
If the ÷ ESP
®warning lamp goes out
before beginning the journey, ESP®is auto-
matically active.

PARKTRONIC
Important safety notes
PARKTRONIC is an electronic parking aid with
ultrasonic sensors. It indicates visually and
audibly the distance between your vehicle
and an object.
PARKTRONIC is only an aid. It is not a replace-
ment for your attention to your immediate
surroundings. You are always responsible for
safe maneuvering, parking and exiting a park- ing space. When maneuvering, parking or
pulling out of a parking space, make sure that
there are no persons, animals or objects in
the area in which you are maneuvering.
!When parking, pay particular attention to
objects above or below the sensors, such
as flower pots or trailer drawbars.
PARKTRONIC does not detect such objects
when they are in the immediate vicinity of
the vehicle. You could damage the vehicle
or the objects.
The sensors may not detect snow and other
objects that absorb ultrasonic waves. Ultrasonic sources such as an automatic
car wash, the compressed-air brakes on a
truck or a pneumatic drill could cause
PARKTRONIC to malfunction.
PARKTRONIC may not function correctly on
uneven terrain.
PARKTRONIC is activated automatically when
you:
Rswitch on the ignition
Rshift the transmission to position D,R or N
Rrelease the electric parking brake.
PARKTRONIC is deactivated at speeds above
11 mph (18 km/h). It is reactivated at lower
speeds.
PARKTRONIC monitors the area around your
vehicle using six sensors in the front bumper
and four sensors in the rear bumper.
Range of the sensors
General notes
PARKTRONIC does not take objects into con-
sideration that are:
Rbelow the detection range, e.g. people, ani-
mals or objects.
Rabove the detection range, e.g. overhang-
ing loads, truck overhangs or loading
ramps.

Keeping Assist is ready for use.
If Standard
is selected, no warning vibra-
tion occurs if:
Ryou have switched on the turn signals. In
this event, the warnings are suppressed
for a certain period of time.
Ra driving safety system intervenes, such
as ABS, BAS or ESP®.
When Adaptive
is selected, no warning
vibration occurs if:
Ryou have switched on the turn signals. In
this event, the warnings are suppressed
for a certain period of time.
Ra driving safety system intervenes, e.g.
ABS, BAS or ESP®.
Ryou accelerate hard, e.g. kickdown.
Ryou brake hard.
Ryou steer actively, e.g. swerve to avoid an
obstacle or change lanes quickly.
Ryou cut the corner on a sharp bend.
