Important safety notes
Accident statistics show that children secured
in the rear seats are safer than children secured in the front-passenger seat. For this reason,
Mercedes-Benz strongly advises that you installa child restraint system on a rear seat. Children
are generally better protected there.
If a child younger than twelve years old and
under 1.50 m in height is travelling in the vehi-
cle:
R always secure the child in a child restraint
system suitable for Mercedes-Benz vehicles.
The child restraint system must be appropri-
ate to the age, weight and size of the child.
R be sure to observe the instructions and safety
notes in this section in addition to the child
restraint system manufacturer's installation
instructions.
R always pay attention to the instructions and
safety notes on the automatic front-
passenger front airbag deactivation system
(Y page 45). 52

WARNING
If you leave children unattended in the vehi-
cle, they may be able to set the vehicle in
motion if, for example, they:
R release the parking brake
R shift the automatic transmission out of park
position P
R start the engine
In addition, they may operate vehicle equip-
ment and become trapped. There is a risk of
an accident and injury.
When leaving the vehicle, always take the key
with you and lock the vehicle. Never leave
children unattended in the vehicle. G
WARNING
If persons (particularly children) are exposed
to heat or cold for a prolonged period, there is a risk of serious or even fatal injuries. Never
leave persons (particularly children) unatten-
ded in the vehicle. G
WARNING
If the child restraint system is placed in direct sunlight, the parts could become very hot.
Children could be suffer burns by touching
these parts, in particular on the metallic parts
of the child restraint system. There is a risk of injury.
If you and your child leave the vehicle, always
make sure that the child restraint system is
not in direct sunlight. Cover it with a blanket, for example. If the child restraint system has
been exposed to direct sunlight, leave it to
cool down before securing the child in it.
Never leave children unattended in the vehi-
cle.
Always ensure that all vehicle occupants have
their seat belts fastened correctly and are sitting
properly. Particular attention must be paid to
children.
Observe the safety notes on the seat belt
(Y page 39) and the information on the correct
use of the seat belt (Y page 40). Child restraint system
If you fit a rearward-facing child restraint system
to the centre rear seat, the rear arm rest must be folded back as far as possible.
Observe the instructions for correct use of the
child restraint system (Y page 57).
For safety reasons, Mercedes-Benz recom-
mends that you only use a child restraint system recommended by Mercedes-Benz
(Y page 61). G
WARNING
If the child restraint system is incorrectly fit-
ted on the seat position suitable for this pur-
pose, it cannot perform its intended protec-
tive function. In the event of an accident,
sharp braking or a sudden change in direction, the child may not be held securely. There is an
increased risk of serious or even fatal injuries.
Observe the manufacturer's installation
instructions and the correct use for the child
restraint system. Make sure that the entire
surface of the child restraint system is resting
on the seat surface. Never place objects
under or behind the child restraint system,
e.g. cushions. Only use child restraint sys-
tems with the original cover designed for
them. Only replace damaged covers with gen- uine covers. G
WARNING
If the child restraint system is fitted incor-
rectly or is not secured, it can come loose in
the event of an accident, heavy braking or a
sudden change in direction. The child
restraint system could be thrown about, strik- ing vehicle occupants. There is an increased
risk of injury, possibly even fatal.
Always fit child restraint systems properly,
even if they are not being used. Make sure
that you observe the child restraint system
manufacturer's installation instructions.

WARNING
Child restraint systems or their securing sys-
tems that have been damaged or subjected to a load in an accident cannot perform their
intended protective function. In the event of
an accident, sharp braking or a sudden
change in direction, the child may not be held securely. There is an increased risk of serious
or even fatal injuries.
Immediately replace child restraint systems
that have been damaged or subjected to a
load in an accident. Have the child restraint
securing systems checked in a qualified spe-
cialist workshop before fitting a child restraint
system again.
The securing systems of child restraint systems
are:
R the seat belt system
R the ISOFIX securing rings
R the Top Tether anchorages
If it is absolutely necessary to fit a child restraint
system on the front-passenger seat, always
observe the information on "Child restraint sys- tems on the front-passenger seat"
(Y page 56).
Observe the warning labels in the vehicle inte-
rior and on the child restraint system.
i It is advisable to use Mercedes-Benz care
products to clean child restraint systems rec- ommended by Mercedes-Benz. Information
can be obtained at a qualified specialist work-
shop. ISOFIX child seat securing system
G
WARNING
ISOFIX child restraint systems do not offer
sufficient protective effect for children whose weight is greater than 22 kg who are securedusing the safety belt integrated in the child
restraint system. The child could, for example, not be restrained correctly in the event of an
accident. This poses an increased risk of
injury or even fatal injury.
If the child weighs more than 22 kg, only use
ISOFIX child restraint systems with which the child is also secured with the vehicle seat belt.
Also secure the child restraint system with the Top Tether belt, if available.
When fitting a child restraint system, be sure to observe the manufacturer's installation and
operating instructions and the instructions for
correct use of the child restraint system
(Y page 57).
Before every trip, make sure that the ISOFIX
child restraint system is engaged correctly in
both ISOFIX securing rings.
! When fitting the child restraint system,
make sure that the seat belt for the centre
seat does not get trapped. Otherwise, the
seat belt could be damaged. X
Install the ISOFIX child restraint system on
both ISOFIX securing rings :.
ISOFIX is a standardised securing system for
specially designed child restraint systems on
the rear seats. The ISOFIX securing rings for two ISOFIX child restraint systems are fitted on the
left and right of the rear seats.
Non-ISOFIX child seats may also be used and
can be installed using the vehicle's seat belt
system. When fitting a child restraint system, be sure to observe the manufacturer's installation
and operating instructions and the instructions
for correct use of the child restraint system
(Y page 57). Top Tether

Child restraint system on the front-
passenger seat
General notes Accident statistics show that children secured
in the rear seats are safer than children secured
in the front-passenger seat. For this reason,
Mercedes-Benz strongly advises that you install a child restraint system on a rear seat.
Vehicles with the automatic front-passenger
front airbag deactivation system: if it is abso-
lutely necessary to fit a child restraint system tothe front-passenger seat, always observe the
information on the "Automatic front-passenger
front airbag deactivation system" (Y page 45).
You can thus avoid the risks that could arise as
a result of:
R a child restraint system that is not detected
by the automatic front-passenger front airbag
deactivation system
R the unintentional disabling of the front-
passenger front airbag
R the unsuitable positioning of the child
restraint system, e.g. too close to the dash-
board Please observe the warning notice on the front-
passenger sun visor, see the illustration. G
WARNING
If you secure a child on the co-driver's seat in a rearward-facing child restraint system and
the PASSENGER AIR BAG ON indicator lamp
lights up, the co-driver's airbag could be
deployed in the event of an accident. The childcould be struck by the airbag. There is an
increased risk of injury, possibly even fatal. In this case, always ensure that the co-driver's
airbag is disabled. The PASSENGER AIRBAG
OFF indicator lamp must light up.
NEVER use a rearward facing child restraint on a seat protected by an ACTIVE AIRBAG in front of
it; DEATH or SERIOUS INJURY to the CHILD can
occur.
If the PASSENGER AIR BAG ON indicator lamp is lit, the front-passenger front airbag is enabled
(Y page 38).
Vehicles without the automatic front-
passenger front airbag deactivation
system If the front-passenger seat of your vehicle is not
equipped with the automatic front-passenger
front airbag deactivation system, this is indica-
ted by a special sticker. The sticker is affixed to
the side of the dashboard on the front-
passenger side. The sticker is visible when you
open the front-passenger door.
If you turn the key to position 2in the ignition
lock, the PASSENGER AIR BAG OFF and
PASSENGER AIR BAG ON indicator lamps light
up briefly. However, they have no function and
do not indicate that there is an automatic front- passenger front airbag deactivation system.
In this case, never fit a rearward-facing child
restraint system on the front passenger seat
(Y page 57).
Observe the following information under "Rear-
ward-facing child restraint system" and
"Forward-facing child restraint system" as well
as information on the suitable positioning of the

If it is absolutely necessary to fit a rearward-
facing child restraint system to the front-
passenger seat, always make sure that the
front-passenger front airbag is disabled. Only if
the PASSENGER AIR BAG OFF indicator lamp is
lit continuously (Y page 38) is the front-
passenger front airbag disabled.
Always observe the information on suitable
positioning of the child restraint system
(Y page 57) in addition to the child restraint
system manufacturer's installation and operat-
ing instructions.
Forward-facing child restraint system If it is absolutely necessary to fit a forward-
facing child restraint system to the front-
passenger seat, always move the front-
passenger seat as far back as possible. 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, as far as possible, lie flat
against the backrest of the front-passenger
seat. The child restraint system must not touch the roof or be put under strain 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 vehicle belt outlet to
the shoulder belt guide on the child restraint
system. The shoulder belt strap must be routed forwards and downwards from the vehicle belt
outlet. If necessary, adjust the vehicle belt out-
let and the front-passenger seat accordingly.
Always observe the information on suitable
positioning of the child restraint system
(Y page 57) in addition to the child restraint
system manufacturer's installation and operat-
ing instructions. Suitable positioning of the child

R PRE-SAFE ®
Brake (Y page 72)
R STEER CONTROL (Y page 74) Important safety notes
If you fail to adapt your driving style or if you are
inattentive, the driving safety systems can nei-
ther 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 staying in lane. Always adapt your driving style to suit the prevailing road and
weather conditions 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 ade-
quate contact between the tyres and the road
surface. Pay particular attention to the informa- tion regarding tyres, recommended minimum
tyre tread depths etc. in the "Wheels and tyres" section (Y page 348).
In wintry driving conditions, always use winter
tyres (M+S tyres) and, if necessary, snow
chains. Only in this way will the driving safety
systems described in this section work as effec-
tively as possible. ABS (Anti-lock Braking System)
General notes 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 8 km/h,
regardless of road-surface conditions. ABS
works on slippery surfaces, even when you only brake gently.
Important safety notes i
Observe the "Important safety notes" sec-
tion (Y page 64). G
WARNING
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- 64

WARNING
When the double locks are 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 with the key or
