Pets 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 maneu- ver, and thereby injure vehicle occupants.
There is a risk of accident and injury.
Never leave animals unattended in the vehi-
cle.
Always secure animals properly when driving,
for instance with a suitable pet carrier. Driving safety systems
Overview of driving safety systems
In this section, you will find information about
the following driving safety systems: R ABS ( Anti-lock BrakingSystem)
(Y page 58)
R BAS ( Brake Assist System) (Y page 59)
R Active Brake Assist (Y page 59)
R ESP ®
(Electronic StabilityProgram)
(Y page 62)
R EBD ( Electronic Brake force Distribution)
(Y page 64)
R ADAPTIVE BRAKE (Y page 64)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 tires and the road
surface. Please pay special attention to the
notes on tires, recommended minimum tire
tread depths, etc. (Y page 263).
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)
General information 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 0025 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 5 mph
(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 58). 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-
tivated. There is an increased danger of skid- ding and accidents.
Drive on carefully. Have ABS checked imme-
diately at a qualified specialist workshop.
When ABS is malfunctioning, other systems,
including driving safety systems, will also
become inoperative. Observe the information
on the ABS warning lamp (Y page 201) and dis-58

WARNING
You could lose control of your vehicle if you do the following while driving:
R adjust the driver's seat, head restraint,
steering wheel or mirrors
R fasten the seat belt
There is a risk of an accident.
Adjust the driver's seat, head restraint, steer-
ing wheel and mirror and fasten your seat belt before starting the engine.
For safety reasons, seat fore-and-aft adjustment on electrically adjustable seats is only possible
for a maximum of two seconds when the vehicleis in motion. The seat fore-and-aft adjustment
can then no longer be set. G
WARNING
If you adjust the seat height carelessly, you or other vehicle occupants could be trapped andthereby injured. Children in particular could
accidentally press the electrical seat adjust-
ment buttons and become trapped. There is a
risk of injury.
While moving the seats, make sure that your
hands or other body parts do not get under the
lever assembly of the seat adjustment sys-
tem. G
WARNING
If head restraints are not adjusted correctly,
they cannot provide protection as intended.
There is an increased risk of injury in the head
and neck area, e.g. in the event of an accident or when braking.
Before driving off, make sure for every vehicle
occupant that the center of the head restraint supports the back of the head at about eye
level.
Using the fore-and-aft adjustment, adjust the
head restraint so that it is as close as possible to your head. G
WARNING
The seat belt does not offer the intended level of protection if you have not moved the back-
rest to an almost vertical position. When brak- ing or in the event of an accident, you could
slide underneath the seat belt and sustain
abdomen or neck injuries, for example. This
poses an increased risk of injury or even fatal
injury.
Adjust the seat properly before beginning
your journey. Always ensure that the backrestis in an almost vertical position and that the
shoulder section of your seat belt is routed
across the center of your shoulder.
! To prevent damage to the seats and the seat
heating, observe the following notes:
R Do not spill liquids onto the seats. Dry the
seats as soon as possible if liquid does get
spilled on the seats.
R If the seat covers are damp or wet, do not
switch on the seat heating. Also, do not use
the seat heating to dry the seats.
R Clean the seat covers as recommended;
see keyword "Care".
R Do not transport heavy loads on the seats.
Do not place pointed objects on the seat
cushions such as knives, nails or tools.
Where possible, use the seats only for car-
rying passengers.
R When operating the seat heating, do not
cover the seats with insulating materials,
e.g. blankets, coats, bags, protective cov-
ers, child seats or booster seats.
! Make sure that there are no objects in the
footwell under or behind the seats when mov- ing the seats back. There is a risk that the
seats and/or the objects could be damaged. Adjusting the seats manually
