Practical hints Battery

The battery is located under the front passenger seat. The battery 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-distance trips, you will need to have the battery charge checked more frequently. When replacing the battery, 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 Light Truck Center about steps you need to observe.

462

G Observe all safety instructions

and precautions when handling automotive batteries.

A Risk of explosion D Keep flames or sparks away

from battery. Do not smoke.

E Wear eye protection. C Keep children away. F Follow the instructions in this

Operator’s Manual.

B Battery acid is caustic. Do not

allow it to come into contact with skin, eyes or clothing. In case it does, immediately flush affected area with clean water and seek medical help if necessary.

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

Mercedes-Benz recommends to replace the battery by an authorized Mercedes-Benz Light Truck Center.

! The battery 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 battery as otherwise the bat- tery will be damaged.

Practical hints Battery

Even though VRLA batteries do not require topping-up of the electrolyte level and cannot be opened to check the electrolyte level, the battery condi- tion must be checked periodically by performing a battery conductance test. Refer to Maintenance Booklet for bat- tery condition testing intervals. As with any other battery, the battery may discharge if the vehicle is not operated for an extended period of time. You can connect a battery maintenance charge unit tested and approved for use on your vehicle model or disconnect the battery to prevent battery discharge. Contact an authorized Mercedes-Benz Light Truck Center for more information.

The factory-equipped VRLA battery is leak-proofed. Only use a battery as re- placement that has the same security features and is of identical size, voltage, and capacity as the factory-equipped battery. The battery, the battery ventilation tube (컄 page 468) and the vent plug (컄 page 468) must always be securely installed when the vehicle is in opera- tion.

Warning!

Jump starting must only be done using the jump-start contacts located in the engine compartment (컄 page 470).

463

Practical hints Battery

Warning!

Failure to follow these instructions can re- sult in severe injury or death.

Observe all safety instructions and precau- tions when handling automotive batteries (컄 page 462). 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.

464

Never loosen or detach battery termi- nal clamps while the engine is running or the SmartKey is in the starter switch. Otherwise the alternator and other electronic components could be se- verely damaged. Have the battery checked regularly by an authorized Mercedes-Benz Light Truck Center. Refer to Maintenance Booklet for main- tenance intervals or contact your au- thorized Mercedes-Benz Light Truck Center for further information.

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.

Disconnecting, removing, reinstalling and reconnecting the battery
