Automatic transmission
Important safety notes
GWARNING
If the engine speed is above the idling speed
and you engage transmission position Dor R,
the vehicle could pull away suddenly. There is
a risk of an accident.
When engaging transmission position Dor R,
always firmly depress the brake pedal and do not simultaneously accelerate.
!Vehicles with automatic transmission may
roll only briefly in the neutral position N. Pro-
longed rolling of the wheels, e.g. when being
towed, will result in transmission damage.

Battery
Important safety notes
Work on the battery, e.g. removing or installing,
requires specialist knowledge and the use of
special tools. Therefore, always have work on
the battery carried out at a qualified specialist
workshop.
GWARNING
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, ABS (anti-lock braking system) or ESP
®
(Electronic Stability Program). The operating
safety of your vehicle may be restricted. You
could lose control of the vehicle, for example:
Rbraking
Rin the event of abrupt steering maneuver
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. You
should have all work involving the battery car-
ried out at a qualified specialist workshop.
Further information can be found under "ABS"
(
Ypage 53) and under "ESP®" (Ypage 54).
GWARNING
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 flammable gas mix is produced when the
battery is charged or when the vehicle is jump-
started.
Always make sure that neither you nor the bat-
tery are electrostatically charged. Electrostatic
charging results, for example, from:
Rwearing synthetic clothing
Rfriction between clothing and the seat
Rdragging or pushing the battery across carpet flooring or any other synthetic materials
Rrubbing the battery with cloths or towels.
Comply with the following safety precautions
and take protective measures when handling
batteries.
Risk of explosion. Explosive oxyhy-
drogen is produced when batteries
are being charged. Only charge bat-
teries in well-ventilated areas.
Fire, open flames and smoking are
therefore prohibited when working
on the battery. Avoid creating
sparks.
Battery acid is caustic. Avoid con-
tact with the skin, eyes or clothing.
Wear acid-proof protective gloves. If
skin or clothes are splashed with
acid, neutralize the splashes imme-
diately with soapy water or an acid
neutralizer, and then clean the affec-
ted areas with water. Consult a doc- tor if necessary.
Wear eye protection. When mixing
water and acid, the liquid can splash
into your eyes. Rinse acid splashes
to the eyes immediately with clean
water and contact a doctor immedi-
ately.
Keep children at a safe distance.
Children are not able to assess the
