Removing/fitting batteries
Important safety notes
! On vehicles with a battery sensor, the neg-
ative terminal clamp forms part of the battery
sensor. Tighten the negative terminal clamp
on the battery pole to a torque of 7 Nm
± 1 Nm. Otherwise, contact is not ensured
and you may damage the terminal clamp, the
battery pole or the battery sensor.
Observe the safety notes on handling batteries.

ening torque of 12 Nm. Do not use a impact
wrench. Otherwise, you could damage the
bolted connection.
