Practical hints Batteries

Your vehicle is equipped with two batter- ies: 앫 The starter battery, located in the en-

gine compartment

앫 The battery for electrical consumers

(consumer battery), located in the trunk

! Do not tow-start the vehicle. The batteries should always be sufficiently charged in order to achieve its rated ser- vice life. Refer to Maintenance Booklet for battery maintenance intervals. If you use your vehicle mostly for short-dis- tance trips, you will need to have the bat- tery charge checked more frequently. When replacing the batteries, always use batteries approved by Mercedes-Benz. If you do not intend to operate your vehicle for an extended period of time, consult an authorized Mercedes-Benz Center about steps you need to observe.

702

Warning!

Observe all safety instructions and precau- tions when handling automotive batteries.

Risk of explosion.

Fire, open flames and smoking are prohibited when handling batteries. Avoid creating sparks.

Battery acid is caustic. Do not allow it to come into contact with skin, eyes or clothing.

Wear suitable protective cloth- ing, especially gloves, apron and faceguard.

Wear eye protection.

Rinse any acid spills immediate- ly with clear water. Contact a physician if necessary.

Keep children away.

Follow the instructions in this Operator’s Manual.

Batteries contain materials that can harm the environment if disposed of improperly. Large 12-volt storage batteries contain lead. Recycling of batteries is the preferred method of disposal. Many states require sellers of batteries to accept old batteries for recycling.

! The consumer battery located in the trunk is a valve-regulated lead acid (VRLA) battery, also referred to as “fleece” battery. Such batteries do not require topping-up of the electrolyte level. VRLA batteries therefore do not have cell caps and the battery cover is non-removable. Do not attempt to open the consumer battery as other- wise the battery will be damaged. Even though VRLA batteries do not require top- ping-up of the electrolyte level and cannot be opened to check the electrolyte level, the bat- tery condition must be checked periodically by performing a battery conductance test. Refer to Maintenance Booklet for battery condition test- ing intervals. As with any other battery, disconnect the con- sumer battery if you do not intend to operate your vehicle for an extended period of time to prevent battery discharge or connect an acces- sory battery charge unit expressly approved by Mercedes-Benz for your vehicle model to main- tain the battery charge. Contact an authorized Mercedes-Benz Center for further information.

! The factory-equipped VRLA battery is leak-proofed. Only use a battery as replacement that has the same security features and is of identical size, voltage, and capacity as the facto- ry-equipped battery. The battery, the battery ventilation and the later- al plug must always be securely installed when the vehicle is in operation.

Warning!

Failure to follow these instructions can re- sult 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.

Practical hints Batteries

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 metal objects on the battery as this could result in a short circuit.

Use leak-proof battery 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 re- lease any possible electrostatic charges.
