Important safety notes
G
WARNING
Battery acid is caustic. There is arisk of
injury.
Avoid contact with skin, eyes or clothing. Do
not inhale gases released from the battery.
When carrying out maintenancework on the

ing, particularly protective eyewear, protec-
tive gloves and an apron. Do not lean over
the battery. Keep the batteries out of the
reach of children.
If you come into contact with battery acid,

WARNING
During charging and jump-starting, explosive
gases can escape from the battery. There is
arisk of an explosion.
Particularly avoid fire, open flames, creating
sparks and smoking. Ensure there is suffi-
cient ventilation while charging and jump-
starting. Do not lean over abattery.
!
Observe the following notes. Batteries or
electronic componentparts in the vehicle
can otherwise be damaged:
R
Do not use rapid charging equipment for
starting assistance.
R
If you use mobile charging equipment
(batteries with mains adapter), disconnect
the mains plug prior to the starting assis-
tance.
R
Only receive starting assistance from
vehicles with a24or12Vsystem.
R
If starting assistance is provided from
vehicles with a12Vsystem, wait about
15 minutes until the starter battery is par-
tially charged.
R
Use jumper cables protected from polar-
ity reversal with acable cross-section of
approximately 35 –50mm
2
and insulated
terminal clamps.
R
Adischarged battery can freeze if outside
temperatures fall below 14 ‡(Ò10 †). In
this case, do not start the engine. Let the
battery thaw first.
!
Do not connect the negative terminal
clamp of the jump lead to the vehicle frame.
Otherwise, engine or transmission compo-
nentscan be damaged.

When removing the jumper cable, let the
engine of the vehicle receiving power run at
idle speed. This will prevent damage to the
vehicle electronics.
