the seats for attaching a belted child restraint
system" or "Suitability of the seats for attach-
ing an ISOFIX child restraint system".
Semi-universal child restraint systems are

approval label. These can be used if the vehi- cle and the seat are listed in the child restraint
system manufacturer's vehicle model list. For more information, contact the child restraint
system manufacturer or visit their website.
Child restraint system on the front-
passenger seat – if it is absolutely necessary
to secure a child in a child restraint system on
the front-passenger seat:
X Always pay attention to the instructions
under "Child restraint system on the front-
passenger seat" (Y page 61).
There you will find instructions on how to
correctly route the shoulder belt strap from
the vehicle belt outlet to the shoulder belt
guide on the child restraint system
(Y page 62).
X Move the front-passenger seat as far back
as possible and fully retract the seat cush-
ion length.
If you secure a child in a forward-facing
child restraint system on the front-
passenger seat, you must also move the
front-passenger seat to the highest posi-
tion.
X Move the backrest to an almost vertical
position.
The entire base of the child restraint sys-
tem must always rest on the seat cushion of the front-passenger seat. The backrest of
the forward-facing child restraint system
must, as far as possible, be resting on the
backrest of the front-passenger seat. The
child restraint system must not touch the
roof or be put under strain by the head
restraint. Adjust the angle of the seat back- rest and the head restraint position accord-
ingly. Also observe the child restraint sys- tem manufacturer's installation instruc-
tions.
X If possible, move the seat cushion angle to
the highest, most vertical position

Suitability of the seats for attaching a belt-secured child restraint system
If you use a baby car seat of category 0 or 0+ or a rearward-facing child restraint system of
category I on a rear seat, you must adjust the driver's or front-passenger seat so that the seat
does not touch the child restraint system.
If you use a category I, forward-facing child restraint system, you should remove the head
restraint of the respective seat (Y page 110), if possible. The backrest of the child restraint
system must, as far as possible, lie flat against the backrest of the seat.
Always observe the notes in the "Child restraint system" section (Y page 58) and the child
restraint system manufacturer's installation instructions.
When you remove the child restraint system you must replace the head restraints again
immediately (Y page 109). All vehicle occupants must adjust their head restraints correctly
before beginning the journey.

This poses an increased risk of injury. X Pull over and stop the vehicle safely as soon as possible, paying
attention to road and traffic conditions.
X Safeguard the vehicle against rolling away (Y page 184).
X Switch the ignition off.
X Open the front-passenger door.
X Remove the child and the child restraint system from the front-

WARNING
Work carried out incorrectly on the battery
can lead, for example, to a short circuit and
thus damage the vehicle electronics. This can lead to function restrictions applying to
safety-relevant systems, e.g the lighting sys-
tem, the ABS (anti-lock braking system) or the
ESP ®
(Electronic Stability Program). The oper-
ating safety of your vehicle may be restricted.
You could lose control of the vehicle, for
example:
R when braking
R in the event of abrupt steering manoeuvres
and/or when the vehicle's speed is not
adapted to the road conditions
There is a risk of an accident.
In the event of a short circuit or a similar inci- dent, contact a qualified specialist workshop
immediately. Do not drive any further. Always have work on the battery carried out at a
qualified specialist workshop.
Further information about ABS (Y page 69)
and ESP ®
(Y page 73). G
WARNING
Electrostatic build-up can lead to the creation of sparks, which could ignite the highly explo-
sive gases of a battery. There is a risk of an
explosion.
Before handling the battery, touch the vehicle body to remove any existing electrostatic
build-up.
The highly flammable gas mixture is created
while the battery is charging and when jump-
starting.
Always make sure that neither you nor the
battery is electrostatically charged. Electro-
static charge is created, for example:
R by wearing synthetic fibre clothing
R by friction between clothing and the seat
R when you pull or push the battery across
carpet or other synthetic materials
R when you rub the battery with a cloth G
WARNING
During the charging process, a battery produ- ces hydrogen gas. If a short circuit occurs or
sparks are created, the hydrogen gas can
ignite. There is a risk of an explosion.
R Make sure that the positive terminal of a
connected battery does not come into con-
tact with vehicle parts.
R Never place metal objects or tools on a bat-
tery.
R It is important that you observe the descri-
bed order of the battery terminals when
connecting and disconnecting a battery.
R When jump-starting, make sure that the
battery poles with identical polarity are
connected.
R It is particularly important to observe the
described order when connecting and dis-
connecting the jump leads.
R Never connect or disconnect the battery
terminals while the engine is running. G
WARNING
Battery acid is caustic. There is a risk of injury. Avoid contact with the skin, eyes or clothing.
Do not breathe in any battery gases. Do not
lean over the battery. Keep the batteries out
of the reach of children. Immediately rinse off
battery acid thoroughly with plenty of clean
water and seek medical attention at once. H
Environmental note Batteries contain pollutants.
It is illegal to dispose of them
with the household rubbish.
They must be collected sep-
arately and disposed of in anenvironmentally responsible
recycling system. Dispose of batteries in an
environmentally responsible
manner. Take discharged

cialist workshop or to a col- Battery (vehicle)
