RIt is particularly important to observe the
describedorder when connecting and dis-
connecting the jumper cables.
RNever connect or disconnect the battery
terminals whil ethe engine is running.
!Alway sconnect the battery in the order
describedb elow. Never mix up the terminal
clamp disconnection/connection order and
never mix up the terminal clamps. You may
otherwise damage the vehicle electronics.
Alway sobserve the prescribedp ositive ter-
minal installation positionw hen doing so.
Otherwise ,the positive clamp may come into
contact with vehicle parts. In this case there is
ar isk that the vehicle may short-circuit and
catch fire.
The following descriptiononc onnecting and
installing the battery is base dupon the example
of the starter battery in the seat base of the
right-hand front seat. The additional battery is
connected and installe dinthe same way as the
starter battery. The auxiliary battery is located in
the seat base of the left-hand front seat.
Example: starter battery
XPlace the battery on the door sill panel as
shown and secure with handles =if neces-
sary.
XConnect positive clamp ;to positive termi-
nal :.A lwaysobserve the positive terminal
installation positions hown when doing so.
The positive leadm ust be routed parallel to
the side of the battery housing in the connec-
tion area.
XPlace the positive clamp cover on positive
terminal :.
XFold both handles =down onto the battery.
XPush the battery into the seat base until the
negative terminal can be connected.
XConnect the negative clamp to negative ter-
minal ?.
XPush the battery into the seat base as far as it
wil lgo.
Open seat base with installe dbattery (example:
right-hand front seat)
XPush breather hose Aonto the battery con-
nection at the top.

ing th evehicle or chargin gthe battery, gases
can escape from th ebattery. Thereisar isko f
an explosion.
Allow th efroze nbattery to thaw out before
chargin gitorjump-starting.
If th eindicator/warning lamps do no tlight up in
th ei nstrumen tcluste rwhen temperatures are
low, it is probably because th edischarged bat-
tery has frozen.S hould this be th ecase, do not
jump-star tthe vehicle or charge th ebattery. The
servic elife of athawed battery may be shorter.
Start-up behavior may deteriorate, in particular
at low temperatures. Hav ethe thawed battery
checked at aqualified specialist workshop.
GWARNING
During chargin gand jump-starting, explosive
gases can escape from th ebattery. Thereisa
ris kofane xplosion.
Particularly avoid fire, open flames, creating
sparks and smoking. Ensure there is sufficient
ventilatio nwhile chargin gand jump-starting.
Do no tlean ove rabattery.
GWARNING
Battery acid is caustic .Thereisar iskofi njury.

iRecharge uninstalled, out of servic ebatter-
ies every 3month s.This will counter self-dis-
charging and prevent battery damage.
Care
!
Dirt ybattery clamps and battery surfaces
cause leak currentsw hich lead to the batter-
ies discharging.
!Do not use cleaning agents containing fuel.
Cleaning agents containing fuel corrode the
battery housing.
!If dirt gets into the battery cell, battery self-
discharge will increase and the battery may
be damaged.
The following points on battery care must be
observed:
XRegularly check the battery terminals and the
fastening of the negative cable to the chassis
to ensure that they are firmly seated.
XAlways keep the battery terminals and battery
surfaces clean and dry.
XLightly grease the undersides of the battery
