Replacing the key batteries
When the key batteries are dead, you will
only be able to unlock the vehicle with the
emergency key element ( page 311). It is
then best to have the batteries replaced at
a qualified specialist workshop, e.g. an
SLR Service Centre.
Risk of poisoning
Batteries contain poisonous and caustic
substances. You should therefore keep bat-
teries out of the reach of children.
If a battery is swallowed, consult a doctor
immediately.
Environmental note
Do not dispose of batteries with the house-
hold rubbish. Batteries contain highly toxic
substances.
Take discharged batteries to a qualified spe-
G
cialist workshop, e.g. a Mercedes-Benz
Service Centre, or to a special collection
point for used batteries.
i
Only replace the batteries in pairs. You can
obtain suitable batteries from any SLR Service
Centre. You can also have the batteries changed
there and return used batteries. In many EU
countries and some other countries, retailers are
legally obliged to take back used batteries.
Practical advice
