Important safety notes
In order for the battery to achieve the maximum possible service life, it must always be sufficiently charged.
Have the battery checked regularly at a qualified specialist workshop, such as an authorized Mercedes-Benz Center.
Adhere to the service intervals indicated in the service booklet or ask a qualified specialist workshop, such as an authorized Mercedes-Benz Center.
Have the battery charge checked more frequently if you use the vehicle mainly for short trips or if you leave it standing idle for a lengthy period.
Only replace a battery with a battery that has been recommended by Mercedes-Benz.
Consult an authorized Mercedes-Benz Center if you wish to leave your vehicle parked for a long period of time.
WARNING
Failure to follow these instructions can result
in severe injury or death.
Never lean over batteries while connecting.
You might get injured.
Battery fluid contains sulfuric acid. Do not
allow this fluid to come in contact with eyes,
skin or clothing. In case it does, immediately
flush affected area with water and seek
medical help if necessary.
A battery will also produce hydrogen gas,
which is flammable and explosive. Keep
flames or sparks away from battery, avoid
improper connection of jumper cables,
smoking etc.
WARNING
Do not place any metal objects on the battery
as this could result in a short circuit.
Use leak-proof batteries only to avoid the risk
of acid burns in the event of an accident.
Take care that you do not become statically
charged, e.g. by wearing synthetic clothing or
rubbing against textiles. For this reason, you
also should not pull or push the battery over
carpets or other synthetic materials.
Never touch the battery first. First, touch the
outside body of the vehicle in order to release
any possible electrostatic charges.
Do not rub the battery with rags or cloths. The
battery could explode if touched due to
electrostatic charge or due to spark
formation.
Before working on the battery, e.g.
loosening the battery terminals, switch off the engine and remove the SmartKey from the ignition. On vehicles with KEYLESS-GO, make sure that the ignition is switched off.
Check that all the indicator lamps in the instrument cluster are off. You may otherwise destroy electronic components, such as the alternator.
Like other batteries, the vehicle battery may discharge over time if you do not use the vehicle. In this case have the battery checked at a qualified specialist workshop, such as an authorized Mercedes-Benz Center. You can also charge the battery with a charger recommended by Mercedes-Benz. Contact an authorized Mercedes- Benz Center for more information.
The battery and the cover of the positive terminal clamp must be installed securely during operation.
Remove the SmartKey if you park the vehicle and do not require any electrical consumers. The vehicle will then use very little energy, thus conserving battery power.
Mercedes-Benz recommends that you do not carry out work on batteries yourself, e.g.
removing or charging. Always have this work performed at a qualified specialist workshop, e.g. an authorized Mercedes-Benz Center.
If the power supply has been interrupted, e.g. if the battery has been reconnected, you must carry out the following tasks:
• set the clock.
On vehicles with COMAND and a navigation system, the clock is set automatically.
• reset the sliding sunroof.
• reset the function for automatically
folding the exterior mirrors in/out by
folding the mirrors out once.
• reset the side windows.
