so, make sure the
45indicator
lamp is illuminated, indicating that the front
passenger front air bag is deactivated.
Should the 45indicator lamp not
illuminate or go out while the restraint is
installed, please check installation.
Periodically check the 45indicator
lamp while driving to make sure the 4
5 indicator lamp is illuminated. If the
45indicator lamp goes out or
remains out, do not transport a child on the
front passenger seat until the system has
been repaired.
A child in a rear-facing child restraint on the
front passenger seat will be seriously
injured or even killed if the front passenger
front air bag inflates.
R If you have to place a child in a forward-
facing child restraint on the front passenger
seat, move the seat as far back as possible,
use the proper child restraint
recommended for the age, size and weight
of the child, and secure child restraint with
the vehicle's seat belt according to the
child seat manufacturer's instructions. G
WARNING
If the child restraint system is installed
incorrectly on a suitable seat, it cannot
protect as intended. The child cannot then be
restrained in the event of an accident, heavy
braking or sudden changes of direction. There
is an increased risk of injury, possibly even
fatal.
Make sure that you observe the child restraint
system manufacturer's installation
instructions and the notes on use. Please
ensure, that the base of the child restraint
system is always resting completely on the
seat cushion. Never place objects, e.g.
cushions, under or behind the child restraint
system. Only use child restraint systems with
the original cover designed for them. Only
replace damaged covers with genuine covers. G
WARNING
If the child restraint system is installed
incorrectly 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,
striking vehicle occupants. There is an
increased risk of injury, possibly even fatal.
Always install child restraint systems
properly, even if they are not being used.
Make sure that you observe the child restraint
system manufacturer's installation
instructions. G
WARNING
Child restraint systems or their securing
systems which have been damaged or
subjected to a load in an accident can no
longer protect as intended. The child cannot
then be restrained in the event of an accident,
heavy braking or sudden changes of direction.
There is an increased risk of injury, possibly
even fatal.
Replace child restraint systems which have
been damaged or subjected to a load in an
accident as soon as possible. Have the
securing systems on the child restraint
system checked at a qualified specialist
workshop, before you install a child restraint
system again. G
WARNING
Infants and small children should never share
a seat belt with another occupant. In the event
of an accident, they could be crushed
between the occupant and seat belt.
A child's risk of serious or fatal injuries is
significantly increased if the child restraints
are not properly secured in the vehicle and/
or the child is not properly secured in the child
restraint.
Children that are too large for a child restraint
must travel in seats using normal seat belts.
Position the shoulder belt across the chest
and shoulder, not face or neck. A booster seat
may be necessary to achieve proper seat belt Children in the vehicle

models and all standard and optional
equipment of your vehicle available at the
time of publication of the Operator's

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,
steering wheel and mirror and fasten your
seat belt before starting the engine. X
Observe the safety guidelines on seat
adjustment (Y page 107).
X Make sure that seat =is adjusted

When adjusting the seat, make sure that:
R you are as far away from the driver's air bag
as possible.
R you are sitting in a normal upright position.
R you can fasten the seat belt properly.
R you have moved the backrest to an almost
vertical position.
R you have set the seat cushion angle so that
your thighs are gently supported.
R you can depress the pedals properly.
X Check whether the head restraint is

When doing so, make sure that you have
adjusted the head restraint so that the back
of your head is supported at eye level by
the center of the head restraint. Also make
sure that you have adjusted the head
restraint so that the back of your head is as
close to the head restraint as possible. This
will be the case if the head restraint is
adjusted correctly (Y page 109).

Correct driver's seat positionSeats, steering wheel and mirrors
we strongly recommend that children be
placed in the rear seat whenever possible.
Regardless of seating position, children 12
years old and under must be seated and
properly secured in an appropriately sized
child restraint system or booster seat
recommended for the size and weight of the
child. For additional information, see the
"Children in the vehicle" section.
A child's risk of serious or fatal injuries is
significantly increased if the child restraints
are not properly secured in the vehicle and/
or the child is not properly secured in the child
restraint.
! 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".
R do not transport heavy loads on the
seats. Do not place sharp objects on the
seat cushions, e.g. knives, nails or tools.
The seats should only be occupied by
passengers, if possible.
R when the seat heating is in operation, do
not cover the seats with insulating
materials, e.g. blankets, coats, bags,
seat covers, child seats or booster seats.
! Make sure that there are no objects in the
footwell or behind the seats when resetting
the seats. There is a risk that the seats
and/or the objects could be damaged.
i It is not possible to remove the head
restraints from the front seats. The rear-
compartment head restraints, however,
can be removed (Y page 110).

The hazard warning lamps automatically
switch on if:
R
an air bag is deployed or
R the vehicle decelerates rapidly from a
speed of above 45 mph (70 km/h) and
comes to a standstill
The hazard warning lamps switch off
automatically if the vehicle reaches a speed
of above 6 mph (10 km/h) again after a full
brake application.
i The hazard warning lamps still operate if
the ignition is switched off. Active light function
The active light function is a system that
moves the headlamps according to the
steering movements of the front wheels. In
this way, relevant areas remain illuminated
while driving. This allows you to recognize
pedestrians, cyclists and animals.
Active: when the lights are switched on. Cornering light function
The cornering light function improves the
illumination of the road over a wide angle in
the direction you are turning, enabling better
visibility in tight bends, for example. It can
only be activated when the low-beam
headlamps are switched on.
Active:
R
if you are driving at speeds below 25 mph
(40 km/h) and switch on the turn signal or
turn the steering wheel
R if you are driving at speeds between
25 mph (40 km/h) and 45 mph (70 km/h)
and turn the steering wheel
Not active: if you are driving at speeds above
25 mph (40 km/h) or switch off the turn
signal or turn the steering wheel to the
straight-ahead position.
The cornering lamp may remain lit for a short
time, but is automatically switched off after
