er's seat
General notes Accident statistics show that children secured
in the rear seats are safer than children
secured in the front seats. For this reason,
Mercedes-Benz strongly advises that you
install a child restraint system on a rear seat.
If it is absolutely necessary to install a child
restraint system on the co-driver's seat, be
sure to observe the instructions and safety
notes on the "Occupant Classification System
(OCS)"

(Y page 54).
This will help to rule out any risks that may
arise due to:
R an incorrectly categorized person in the co-
driver's seat
R an unintentionally deactivated co-driver's air
bag
R an unfavorable positioning of the child
restraint system, e.g. too near to the dash-
board
Rearward-facing child restraint system If circumstances require you to install a rear-
ward-facing child restraint system on the co-
driver's seat, you must always make sure that
the co-driver's air bag is deactivated. The co-
driver's air bag is deactivated only when the
PASSENGER AIR BAG OFF indicator lamp is lit
continuously ( Y page

54).
Always comply with the manufacturer's instal-
lation and operating instructions for the child
restraint system.
Forward-facing child restraint system If it is absolutely necessary to secure a child in
a forward-facing child restraint system on the
co-driver's seat, you must always move the co-
driver's seat as far back as possible. The base
of the child restraint system must always rest
on the seat cushion of the co-driver's seat. As
much as possible of the backrest of the child
restraint system must be resting on the back-
rest of the co-driver's seat. The child restraint
system may 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 the shoulder belt is correctly secured,64

running from the belt outlet to the belt guide
of the child restraint system. The shoulder belt
strap must be routed forward and down from
the vehicle belt outlet. Adjust the belt outlet
and co-driver's seat as required.
Always comply with the manufacturer's instal-
lation and operating instructions for the child
restraint system. Override feature/child-proof locks
Important safety notes G
WARNING
If children are traveling in the vehicle, they
could in particular:
R open doors, thereby endangering other
persons or road users.
R get out and be struck by oncoming traffic.
R operate vehicle equipment and become
trapped.
There is a risk of an accident and injury.
Always activate the child-proof locks and
override feature if children are traveling in
the vehicle. When leaving the vehicle,
always take the key with you and lock the

WARNING
If children are left unsupervised in the vehi-
cle, they could, in particular:
R open doors, thereby endangering other
persons or road users.
R get out and be struck by oncoming traffic.
R operate vehicle equipment and become
trapped, for example.
In addition, children could set the vehicle in
motion, for example, if they:
R release the parking brake.
R change the transmission position.
R start the vehicle. There is a risk of accident and injury.
Never leave children unsupervised in the
vehicle.
When leaving the vehicle, always take the
SmartKey with you and lock the vehicle.
Keep the SmartKey out of the reach of chil-
dren.
G
WARNING
If persons, particularly children are subjec-
ted to prolonged exposure to extreme heat
or cold, there is a risk of injury, possibly
even fatal. Never leave children unattended
in the vehicle. G
WARNING
If the child restraint system is subjected to
direct sunlight, parts may get very hot. Chil-
dren may burn themselves on these parts,
particularly on the metal parts of the child
restraint system. There is a risk of injury.
If you leave the vehicle, taking the child with
you, always ensure that the child restraint
system is not exposed to direct sunlight.
Protect it with a blanket, for example. If the
child restraint system has been exposed to
direct sunlight, let it cool down before secur-
ing the child in it. Never leave children unat-
tended in the vehicle. Children in the vehicle

G
WARNING
If you leave animals unsupervised or unse-
cured in the vehicle, they may press buttons
or switches, for instance.
In this way, animals may:
R activate vehicle equipment and become
trapped, for example
R switch systems on or off and thereby
endanger other road users
Furthermore, unsecured animals may be
flung around inside the vehicle in the event
of an accident or abrupt steering or braking maneuver, and thereby injure vehicle occu-
pants. There is a risk of accident and injury.
Never leave animals unattended in the vehi-
cle.
Always secure animals properly when driv-
ing, for instance with a suitable pet carrier. Driving safety systems
Overview
In this section, you will find information about
the following driving safety systems:
R EBD ( Electronic Brake Force Distribution)
R ABS ( Anti-lock Braking System)
R BAS ( Brake A ssist System)
R ESP ®
(Electronic Stability Program) 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 accident nor over-
ride the laws of physics. Driving safety sys-
tems are merely aids designed to assist driv-
ing. You are responsible for the distance to the
vehicle in front, for vehicle speed, braking in
good time and for staying in your lane. Always
adapt your driving style to the prevailing road
and weather conditions and maintain a suffi-
cient, safe distance from other road users.
Drive carefully.
Please note that the driving safety systems
described only work optimally when the follow-
ing conditions are fulfilled:
R there is adequate contact between the tires
and the road surface.
R you use winter tires

(M+S tires) with snow
chains if necessary, when the road condi-
tions are wintry.
R the speed information determined by the
vehicle is within the legally prescribed dis-
play accuracy.
Pay particular attention to the information
regarding tires, tire tread and winter operation
under "Wheels and tires" (Y page 278). 66

the key.
If the vehicle has been locked using the lock-
ing button for the central locking and a door is
opened from the inside, only the door that has

WARNING
When you open the sliding door, the sliding
door could hit other people as it moves
backwards. There is a risk of injury.
Only open the sliding door when traffic con-
ditions permit.
! Do not use the lower sliding door guide
(carriage) as a step. Otherwise, you could
damage the paneling and/or the sliding
door mechanism.
You must reset the electric sliding door if
there has been a malfunction or an interrup-
tion in the voltage supply
(Y page 80).
i Please note, if the child-proof locks have
been activated, you cannot open the sliding

sliding door from the inside if the child-proof
locks have not been activated. Further infor-
mation can be found under "Child-proof
locks for the sliding door" (Y page 66) and
"Opening/closing from the inside"
(Y page 79). Obstacle detection with reversing
feature
The sliding door is equipped with automatic
obstacle detection with reversing feature. If a
solid object blocks or restricts the sliding door
during the automatic closing process, the slid-
ing door opens again automatically. If the slid-
ing door is obstructed during the opening pro- cedure, it moves back a few centimeters in the
opposite direction and stops.
Automatic obstacle detection with reversing
feature is only an aid. It is not a substitute for
your attentiveness when closing the electrical
sliding door.
If an obstacle is detected, the display shows
the Left-hand Electric Sliding Door
Obstruction Detected message for exam-
ple, and five warning tones sound. G
WARNING
The reversing feature does not react:
R to soft, light and thin objects, e.g. small
fingers
R over the last 8 mm of the closing move-
ment
This means that the reversing feature can-
not prevent someone being trapped in these
situations. There is a risk of injury.
When closing, make sure that no-one has
any parts of the body within the closing
area.
If someone is trapped:
R press the 5 button on the SmartKey,
or
R pull the exterior door handle, or
R press the corresponding sliding door but-
ton in the center console, or
R press the button on the door frame, or
