Always observe the child restraint system
manufacturer's installation and operating
instructions.
Forward-facing child restraint system If you secure a child in a forward-facing child
restraint system on the front-passenger seat,
always move the front-passenger seat as far
back as possible. Fully retract the seat cush-
ion length. 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 lie as flat as possible against the backrest of thefront-passenger seat. The child restraint sys-
tem must not touch the roof or be subjected
to a load 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 front-passenger seat-belt
extender to the shoulder belt guide on the
child restraint system. The shoulder belt strap
must be routed forwards from the retracted
front-passenger seat seat-belt extender.
Always observe the child restraint system
manufacturer's installation and operating
instructions. Pets in the vehicle
G
WARNING
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 BrakingSystem)
(Y page 66)
R BAS ( Brake Assist System) (Y page 66)
R BAS PLUS (B rakeAssist System PLUS) with
Cross-Traffic Assist (Y page 67)
R COLLISION PREVENTION ASSIST PLUS
(distance warning function and Adaptive
Brake Assist) (Y page 68)
R ESP ®
(Electronic StabilityProgram)
(Y page 71)
R EBD ( Electronic Brake force Distribution)
(Y page 73)
R ADAPTIVE BRAKE (Y page 73)
R PRE-SAFE ®
Brake (Y page 73)
R STEER CONTROL (Y page 75) 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. Driving safety systems
65Safety Z
X
Before starting off, adjust the rear-view mir-
ror and the exterior mirrors in such a way
that you have a good view of road and traf-
fic conditions (Y page 114).
X Store the seat, steering wheel and exterior
mirror settings using the memory function
(Y page 117). Seats
Important safety notes
G
WARNING
Children could become trapped if they adjust the seats, particularly when unattended.
There is a risk of injury.
When leaving the vehicle, always take the
SmartKey with you and lock the vehicle. Never leave children unsupervised in the vehicle.
The seats can still be adjusted when there is
no SmartKey in the ignition lock. G
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. 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
When you adjust a seat, you or other vehicle
occupants could become trapped, e.g. on the seat guide rail. There is a risk of injury.
Make sure when adjusting a seat that no one
has any body parts in the sweep of the seat. G
WARNING
If head restraints are not installed and adjus-
ted 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.
Always drive with the head restraints instal-
led. 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. 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 backrest
is in an almost vertical position and that the
shoulder section of your seat belt is routed
across the center of your shoulder.
! To avoid damage to the seats and the seat
heating, observe the following information:
R keep liquids from spilling on the seats. If
liquid is spilled on the seats, dry them as
soon as possible.
R if the seat covers are damp or wet, do not
switch on the seat heating. The seat
heating should also not be used to dry
the seats.
R clean the seat covers as recommended;
see "Interior care". Seats

0050Solutions The seat heating has
switched off prema-
turely or cannot be
switched on. The on-board voltage is too low because too many electrical con-
sumers are switched on.
X Switch off electrical consumers that you do not need, such as
the rear window defroster or interior lighting.
Once the battery is sufficiently charged, the seat heating can be
switched back on manually. Switching the seat ventilation on/off
Front seats The three blue indicator lamps in the buttons
indicate the blower setting you have selected.
X Turn the SmartKey to position 1or 2in the
ignition lock (Y page 147).
X To switch on: press button0043repeatedly
until the desired blower setting is set.
X To switch off: press button0043repeatedly
until all the indicator lamps go out.
i If the battery voltage is too low, the seat
ventilation may switch off.
i You can open the side windows using the
"Convenience opening" feature
(Y page 95). The seat ventilation of the
driver's seat automatically switches to the
highest level.
i When the vehicle is stationary, the fan
speed can be reduced automatically. This
reduces the noises of the seat ventilation. Seats

WARNING
Children could become trapped if they acti-
vate the memory function, particularly when
unattended. There is a risk of injury.
When leaving the vehicle, always take the
SmartKey with you and lock the vehicle. Never leave children unsupervised in the vehicle. Storing settings
With the memory function, you can store up
to three different settings, e.g. for three dif-
ferent people.
The following settings are stored as a single
memory preset:
R seat, backrest, head restraint position and
contour of the backrest in the lumbar
region
R active multicontour seat: side bolsters of
the backrest, shoulder of the backrest, con-
tour of the backrest, dynamic function level
R seat heating: distribution of the heated sec-
tions of the seat cushion and backrest
R driver's side: position of the exterior mir-
rors on the driver's and front-passenger
sides
R position of the head-up display X
Adjust the seat accordingly (Y page 104).
X On the driver's side, adjust the steering
wheel (Y page 110) and the exterior mirrors
(Y page 114).
X Press memory button Mand one of the
storage position buttons 1,2or 3within
three seconds.
The settings are stored in the selected pre- set position. A tone sounds when the set-
tings have been completed. Calling up a stored setting
X Press and hold the corresponding storage
position button 1,2or 3until:

R Steering wheel
R Exterior mirrors
R Head-up display

functions stop immediately. The multicon-
tour seat setting or the 4-way lumbar sup-
port is still carried out. Memory function

If the coolant temperature is above 257 ‡
(125 †) do not drive any further. The
engine will otherwise be damaged.

lower section of the tachometer (Y page 31).
Under normal operating conditions and with
the specified coolant level, the coolant tem-
