R
the engine is switched off and the fuel supply
is cut off
R vehicles with the Mercedes-Benz emergency
call system: automatic emergency call Children in the vehicle
Important safety notes
If a child younger than twelve years old and
under 1.50 min 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 be sure to observe the instructions and safety
notes on the automatic front-passenger front airbag deactivation system (Y page 41).G
WARNING
If you leave children unattended in the vehi-
cle, they could set the vehicle in motion by, for example:
R releasing the parking brake
R shifting the transmission into neutral
R starting the engine
They could also operate the vehicle's 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 36) and the information on the correct
use of the seat belt (Y page 37). Child restraint system
Observe the instructions for correct use of the
child restraint system (Y page 51).
For safety reasons, Mercedes-Benz recom-
mends that you use only a child restraint system
recommended by Mercedes-Benz
(Y page 52). 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. Children in the vehicle

Turn on ESP
®
and adapt your driving style
accordingly. When the outside temperature
falls below 10 †, use M+S tyres.
i Different driving styles may lead to higher
levels of tyre wear, meaning the tyres may
wear down to the minimum tyre tread depth
after less mileage. Regular checking of wheels and tyres
G
WARNING
Damaged tyres can cause tyre inflation pres-
sure loss. As a result, you could lose control of your vehicle. There is a risk of accident.
Check the tyres regularly for signs of damageand replace any damaged tyres immediately.
Check wheels and tyres for damage at least
once a month. Check wheels and tyres after
driving off-road or on rough roads. Damaged
wheels can cause a loss of tyre pressure. Pay
particular attention to damage such as:
R cuts in the tyres
R punctures
R tears in the tyres
R bulges on the tyres
R deformation or severe corrosion on wheels
Regularly check the tyre tread depth and the
condition of the tread across the whole width of
the tyre (Y page 262). If necessary, turn the
front wheels to full lock in order to inspect the
inner side of the tyre surface.
All wheels must have a valve cap to protect the
valve against dirt and moisture. Do not fit any-
thing onto the valve other than the standard
valve cap or other valve caps approved for your vehicle by Mercedes-Benz. Do not fit any other
valve caps or systems, e.g. tyre pressure moni-
toring systems.
Regularly check the pressure of all the tyres,
particularly prior to long trips. Adjust the tyre
pressure as necessary (Y page 264).
Observe the notes on the emergency spare
wheel (Y page 273). The service life of tyres depends on various fac-
tors, including the following:
R driving style
R tyre pressure
R mileage Notes on the tyre tread
G
WARNING
Insufficient tyre tread will reduce tyre trac-
tion. The tyre is no longer able to dissipate
water. This means that on wet road surfaces, the risk of aquaplaning increases, in particularwhere speed is not adapted to suit the driving
conditions. There is a risk of accident.
If the tyre pressure is too high or too low, tyres may exhibit different levels of wear at differ-
ent locations on the tyre tread. Thus, you
should regularly check the tread depth and
the condition of the tread across the entire
width of all tyres.
Minimum tyre tread depth for:
R summer tyres: 3 mm
R M+S tyres: 4 mm
For safety reasons, replace the tyres before
the legally prescribed limit for the minimum
tyre tread depth is reached. Selecting, fitting and replacing tyres
G
WARNING
Exceeding the stated tyre load-bearing capa-
city and the approved maximum speed could
lead to tyre damage or the tyre bursting. There is a risk of accident.
Therefore, only use tyre types and sizes
approved for your vehicle model. Observe the
tyre load rating and speed rating required for your vehicle.
Pay special attention to country-specific
requirements for tyre approval. These require-
ments can stipulate a specific tyre type for your
vehicle. Furthermore, the use of certain tyre
types in certain regions and areas of operation
can be highly beneficial. You can find further 262
