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.

503

Practical hints Battery

! 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 battery will be dam- aged. Even though VRLA batteries do not require topping-up of the electrolyte level and cannot be opened to check the electrolyte level, the battery condition must be checked periodically by performing a battery conductance test. Refer to Maintenance Booklet for battery 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 dis- connected the battery to prevent battery dis- charge. Contact an authorized Mercedes-Benz Light Truck Center for more information.

504

! 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 factory-equipped battery. The battery, the battery ventilation and the later- al plug must always be securely installed when the vehicle is in operation.

Warning!

Jump starting must only be done using the jump-start contacts located in the engine compartment (컄 page 511).

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 503). 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.

! Never loosen or detach battery terminal clamps while the engine is running or the SmartKey is in the starter switch. Otherwise the alternator and other electronic components could be severely damaged. Have the battery checked regularly by an autho- rized Mercedes-Benz Light Truck Center.

왔 Jump starting

Warning!

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 battery is discharged, the engine can be started with jumper cables and the bat- tery of another vehicle. Observe the follow- ing: 앫 Jump starting should only be performed using the jump-start contacts in the en- gine compartment (컄 page 512).

앫 Jump starting should only be performed

when the engine and catalytic converter1 are cold.

앫 Do not start the engine if the battery is

frozen. Let the battery thaw out first.

앫 Only jump start from batteries with the same voltage rating (12V). Jump start- ing with a more powerful battery could damage the vehicle’s electrical system, which will not be covered by the Mercedes-Benz Limited Warranty.

앫 Only use jumper cables with sufficient

cross-section and insulated terminal clamps.

앫 Always make sure the jumper cables

are not on or near pulleys, fans or other parts that move when the engine is started or running.

! Do not tow-start the vehicle. ! Avoid repeated and lengthy starting attempts. Do not attempt to start the engine using a battery quick charge unit. If the engine does not run after several unsuc- cessful starting attempts, have it checked at the nearest authorized Mercedes-Benz Light Truck Center. Excessive unburned fuel generated by repeated failed starting attempts may damage the cata- lytic converter1. Make sure the jumper cables do not have loose or missing insulation.

Stranded vehicle

Freeing a stranded vehicle, on which the wheels are dug into sand or mud, should be done with the greatest of care, espe- cially if the vehicle is heavily loaded. Avoid pulling the vehicle abruptly or diago- nally, since it could result in damage to the chassis alignment. Never try to free a vehicle that is still cou- pled to a trailer. If possible, a vehicle equipped with trailer hitch receiver should be pulled backward in its own previously made tracks.

Practical hints Fuses

The electrical fuses in your vehicle serve to switch off malfunctioning power circuits. If a fuse is blown, the components and systems secured by that fuse will stop operating.

Warning!

Only use fuses approved by Mercedes-Benz with the specified amperage for the system in question and do not attempt to repair or bridge a blown fuse. Using other than approved fuses or using repaired or bridged fuses may cause an overload leading to a fire, and/or cause damage to electrical components and/or systems. Have the cause determined and remedied by an authorized Mercedes-Benz Light Truck Center

i A blown fuse must be replaced by an appro- priate spare fuse (recognizable by its color or the fuse rating given on the fuse) of the amperage recommended in the fuse chart. Any Mercedes-Benz Light Truck Center will be glad to advise you on this subject.

518

If a newly inserted fuse blows again, have the cause determined and rectified by an authorized Mercedes-Benz Light Truck Center. A fuse chart explains the fuse allocation and fuse amperages. It is located in the cargo compartment with the vehicle tool kit (컄 page 469). The electrical fuses are located in different fuse boxes: 앫 on the passenger side of the engine

compartment (컄 page 519) 앫 in the cargo compartment

(컄 page 519)

앫 in the passenger compartment

(컄 page 520)

Before replacing fuses: 왘 Apply the parking brake (컄 page 65). 왘 Make sure automatic transmission is

set to position P (컄 page 192). The gear position indicator in the multifunction display should be on P.

왘 Turn off all electrical consumers. 왘 Turn off the engine (컄 page 66). 왘 Remove the SmartKey from the starter

switch. Vehicles with KEYLESS-GO*: 왘 Open the driver’s door (this puts the starter switch to position 0, same as with the SmartKey re- moved from starter switch). The driver’s door can then be closed again.

왔 Rims and tires ! Only use tires which have been tested and approved by Mercedes-Benz. Tires approved by Mercedes-Benz are developed to provide best possible performance in conjunction with the driving safety systems on your vehicle such as ABS or ESP®. Tires specially developed for your vehicle and tested and approved by Mercedes-Benz can be identified by finding the following on the tire’s sidewall: 앫 MO = Mercedes-Benz Original equipment

tires

Using tires other than those approved by Mercedes-Benz may result in damage that is not covered by the Mercedes-Benz Limited Warranty.

! Using tires other than those approved by Mercedes-Benz can have detrimental effects, such as 앫 poor handling characteristics 앫 increased noise 앫 increased fuel consumption Moreover, tires and rims not approved by Mercedes-Benz may, under load, exhibit dimen- sional variations and different tire deformation characteristics that could cause them to come into contact with the vehicle body or axle parts. Damage to the tires or the vehicle may be the result.

i Further information on tires and rims is available at any authorized Mercedes-Benz Light Truck Center. A placard with the recommended tire inflation pressures is located on the driver’s door B-pillar (컄 page 366). Some vehicles may have supplemental tire inflation pressure infor- mation for driving at high speeds (컄 page 372) or for vehicle loads less than the maximum loaded vehicle condition (컄 page 372). If such information is provided, it can be found on the placard located on the inside of the fuel filler flap.

Technical data Rims and tires

The tire inflation pressure should be checked regularly and should only be adjusted on cold tires. Follow tire manufacturer’s maintenance recommendation included with vehicle. i The following pages also list the approved wheel rim and tire sizes for equipping your vehi- cles with winter tires. Winter tires are not avail- able as standard or optional factory equipment, but can be purchased from an authorized Mercedes-Benz Light Truck Center. Depending on vehicle model and the standard or optional factory-equipped wheel rim/tire configuration on your vehicle (Appearance Package, Sport Package etc.), equipping your vehicle with winter tires approved for your vehicle model may also require the purchase of two or four wheel rims of the recommended size for use with these winter tires.

Brake fluid

Warning!

Premium unleaded gasoline (gasoline engine)

Warning!

During vehicle operation, the boiling point of the brake fluid is continuously reduced through the absorption of moisture from the atmosphere. Under extremely strenuous operating conditions, this moisture content can lead to the formation of bubbles in the system, thus reducing the system’s efficiency.

Therefore, the brake fluid must be replaced regularly. Refer to your vehicle’s Maintenance Booklet for replacement interval.

Only brake fluid approved by Mercedes-Benz is recommended. Your authorized Mercedes-Benz Light Truck Center will provide you with additional information.

Gasoline is highly flammable and poisonous. It burns violently and can cause serious personal injury.

Never allow sparks, flame or smoking mate- rials near gasoline!

Turn off the engine before refueling.

Whenever you are around gasoline, avoid in- haling fumes and skin or clothing contact, extinguish all smoking materials.

Direct skin contact with gasoline and the in- halation of gasoline vapors are damaging to
