2014 MERCEDES-BENZ CLS COUPE tow

When deployed, the windowbag enhances the
level of protection for the head. However, it
does not protect the chest or arms.
In the event of a side impact, the windowbag
is deployed on the side on which the impact
occurs.
If the system determines that they can offer
additional protection to that provided by the
seat belt, a windowbag may be deployed in
other accident situations (Y page 51).Deployment of belt tensioners and air-
bags
Important safety notes G
WARNING
After the airbag deploys, the airbag parts are
hot. There is a risk of injury.
Do not touch the airbag parts. Have a
deployed airbag replaced at a qualified spe-
cialist workshop as soon as possible. G
WARNING
Pyrotechnic seat belt tensioners that have
been deployed are no longer operational and
are unable to perform their intended protec-
tive function. This poses an increased risk of
injury or even fatal injury.
Therefore, have pyrotechnic belt tensioners
which have been triggered immediately
replaced at a qualified specialist workshop.
Mercedes-Benz recommends that after an
accident, you have your vehicle towed to a
qualified specialist workshop. This is particu- larly important after the seat belt tensioners
have been triggered or after airbags have
been deployed.
An electric motor is used by PRE-SAFE ®
to
trigger the tightening of the seat belt in haz-
ardous situations. This procedure is reversi-
ble.
If belt tensioners are triggered or the airbags
are deployed, you will hear a bang, and a small amount of powder may also be released. The
6 restraint system warning lamp lights up.
Only in rare cases will the bang affect your
hearing. The powder that is released gener-
ally does not constitute a health hazard but
can cause short-term breathing difficulties for people with asthma or breathing problems. If
it is safe to do so, leave the vehicle immedi-
ately or open a window to avoid experiencing potential breathing difficulties.
Mode of operation During the first stage of a collision, the
restraint system control unit evaluates impor-
tant physical data relating to vehicle deceler- ation or acceleration, such as:
R duration
R direction
R intensity
Based on the evaluation of this data, the seat belt tensioner is triggered by the restraint
system control unit in the event of a frontal or
rear collision.
The belt tensioner can only be triggered if:
R the ignition is switched on
R the components of the restraint system are
operational; see the "Restraint system
warning lamp" section (Y page 43)
R the seat belt buckle tongue is engaged in
the belt buckle on your front seat
The belt tensioners in the rear compartment
are triggered independently of the lock status of the seat belts.
In certain frontal collision situations, further
components of the restraint system are acti-
vated independently of each other if the
restraint system control unit determines that the accident is severe:
R front airbags and driver's kneebag
R windowbag, if it is determined that it can
offer additional protection to the seat belt
for vehicle occupants
Depending on the classification of the person in the front-passenger seat, the front- Occupant safety

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 sit-
ting properly. Particular attention must be
paid to children.
Observe the safety notes on the seat belt
(Y page 44) and the notes on correct use of
seat belts (Y page 45). Child restraint system
Observe the instructions for correct use of
the child restraint system (Y page 63).
For safety reasons, Mercedes-Benz recom-
mends that you only use a child restraint sys-
tem recommended by Mercedes-Benz
(Y page 66). 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.
You will find further information on stowing
objects, luggage or loads under "Loading
guidelines" (Y page 300). G
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.
If it is absolutely necessary to carry a child on the front-passenger seat, be sure to observe
the information on "Child restraint systems
on the front-passenger seat" (Y page 61).
You can also find information on disabling the
front-passenger front airbag.
Observe the warning labels in the vehicle inte- rior and on the child restraint system. 56

tion (Y page 70). G
WARNING
If ESP ®
is malfunctioning, ESP ®
is unable to
stabilise the vehicle. In addition, other driving
safety systems are switched off. This increa-
ses the risk of skidding and an accident.
Drive on carefully. Have ESP ®
checked at a
qualified specialist workshop.
! Vehicles with 4MATIC: switch off the igni-
tion when the parking brake is being tested
using a dynamometer.
Application of the brakes by ESP ®
may oth-
erwise destroy the brake system.
! Vehicles with 4MATIC: function or per-
formance tests may only be carried out on
a 2-axle dynamometer. Before operating
the vehicle on such a dynamometer, please
consult a qualified specialist workshop.
You could otherwise damage the drive train
or the brake system.
Vehicles without 4MATIC: when towing your
vehicle with the rear axle raised, it is impor-
tant that you observe the notes on ESP ®
(Y page 359).
ESP ®
is deactivated if the åwarning lamp
in the instrument cluster lights up continu-
ously when the engine is running.
If the ÷ warning lamp and the åwarn-
ing lamp are lit continuously, ESP ®
