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.

컄컄

703

Practical hints Batteries

컄컄

Do not rub the battery with rags or cloths. The battery could explode if touched due to electrostatic charge or due to spark forma- tion.

! Switch off the engine and switch off the ve- hicle’s internal electrical functions (컄 page 705) before you disconnect or remove the battery’s terminal clamps. You could otherwise destroy electronic assemblies such as the generator. Have the battery checked regularly by an autho- rized Mercedes-Benz Center. Refer to Mainte- nance Booklet for maintenance intervals or contact an authorized Mercedes-Benz Center for further information.

! Do not connect any consumers directly to the starter battery. The starter battery will other- wise be discharged.

i Only replace a discharged battery with a bat- tery recommended by Mercedes-Benz. The con- sumer battery is installed in the trunk in such a way that it is safeguarded as much as possible against mechanical destruction in the event of an accident.

704

i Remove SmartKey from starter switch (vehi- cles with KEYLESS-GO*: Make sure the vehicle’s on-board electronics have status 0) (컄 page 365) when you turn off the engine and no longer require any electrical consumers. The vehicle then uses very little power and the con- sumer battery is spared.

Disconnecting starter battery

! Always disconnect the starter battery in the order described below. You could otherwise damage the vehicle’s electronics.

! Switch off the vehicle’s internal electrical functions before disconnecting the starter bat- tery. If the vehicle is stationary for more than one hour with the SmartKey removed, you do not need to switch off the vehicle’s internal electrical functions. 왘 Secure vehicle in place with electronic

왔 Jump starting

Warning!

! Do not tow-start the vehicle.

! Jump starting should only be performed on the starter battery installed in the engine com- partment. Avoid repeated and lengthy starting attempts. Do not attempt to start the engine using a bat- tery quick charge unit. If engine does not run after several unsuccessful starting attempts, have it checked at the nearest authorized Mercedes-Benz Center. Excessive unburned fuel generated by repeated failed starting attempts may damage the catalyt- ic converter and may present a fire risk. Make sure the jumper cables do not have loose or missing insulation. Make sure the cable clamps do not touch any other metal part while the other end is still at- tached to a battery.

Failure to follow these directions will cause damage to the electronic components, and can lead to a battery explosion and severe injury or death.

Never lean over batteries while connecting or jump starting, 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 very explosive. Keep flames or sparks away from battery, avoid improper connection of jumper cables, smoking, etc.

Attempting to jump start a frozen battery can result in it exploding, causing personal injury.

Read all instructions before proceeding.

Practical hints Jump starting

If the starter battery is discharged, the en- gine can be started with jumper cables and the battery of another vehicle. Observe the following: 앫 Jump starting should only be performed when the engine and catalytic convert- er are cold.

앫 Do not start the engine if the battery is

frozen. Let the battery thaw out first. 앫 Only use 12-volt battery to jump start your vehicle. Jump starting with a high- er voltage battery could damage the ve- hicle’s electrical system, which will not be covered by the Mercedes-Benz Lim- ited Warranty.

앫 Only use jumper cables with sufficient

cross-section and insulated terminal clamps.

앫 Always make sure that the jumper ca- bles are not on or near pulleys, fans or other parts that move when an engine is started or running.
