Pets in the vehicle
GWARNING
If you leave animals unattended or unsecured in the vehicle, they could press buttons or
switches, for example.
As a result, they could: R activate vehicle equipment and become
trapped, for example
R activate or deactivate systems, thereby
endangering other road users
Unsecured animals could also be flung around
the vehicle in the event of an accident or sud- den steering or braking, thereby injuring vehi-
cle occupants. There is a risk of an accident
and injury.
Never leave animals unattended in the vehi-
cle. Always secure animals properly during
the journey, e.g. use a suitable animal trans-
port box.
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 Braking System)
( Y page 61)
R BAS ( Brake Assist System) ( Ypage 61)
R COLLISION PREVENTION ASSIST PLUS (Y page 62)
R ESP ®
(E lectronic Stability Program)
( Y page 64)
R EBD ( Electronic Brake force Distribution)
( Y page 66)
R ADAPTIVE BRAKE ( Ypage 66)
R STEER CONTROL ( Ypage 66)
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 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 stay- ing in lane. Always adapt your driving style to
suit the prevailing road and weather condi-
tions 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
adequate contact between the tires and the
road surface. Please pay special attention to
the notes on tires, recommended minimum
tire tread depths, etc. ( Ypage 302).
In wintry driving conditions, always use winter
tires (M+S tires) and if necessary, snow
