Jump-starting

For the jump-starting procedure, use only the jump-starting connection point, consisting of a positive terminal and an earth point, in the engine compartment.
All vehicles except Mercedes-AMG vehicles:

WARNING
Battery acid is caustic. There is a risk of injury.
Avoid contact with skin, eyes or clothing. Do not inhale any battery gases. Do not lean over the battery. Keep children away from batteries. Wash away battery acid immediately with plenty of clean water and seek medical attention.

During charging and jump-starting, explosive gases can escape from the battery. There is a risk of an explosion.
Particularly avoid fire, open flames, creating sparks and smoking. Ensure there is sufficient ventilation while charging and jump-starting. Do not lean over a battery.
During the charging process, a battery produces hydrogen gas. If a short circuit occurs or sparks are created, the hydrogen gas can ignite. There is a risk of an explosion.

• Make sure that the positive terminal of a connected battery does not come into contact with vehicle parts.
• Never place metal objects or tools on a battery.
• It is important that you observe the described order of the battery terminals when connecting and disconnecting a battery.
• When jump-starting, make sure that the battery poles with identical polarity are connected.
• It is particularly important to observe the described order when connecting and disconnecting the jumper cables.
• Never connect or disconnect the battery terminals while the engine is running.

A discharged battery can freeze at temperatures below freezing point. When jump-starting the vehicle or charging the battery, gases can escape from the battery. There is a risk of an explosion.
Allow the frozen battery to thaw out before charging it or jump-starting it.

Avoid repeated and lengthy starting attempts. Otherwise, the catalytic converter could be damaged by the non-combusted fuel.
If, at low temperatures, the indicator lamps/warning lamps in the instrument cluster do not light up, it is highly likely that the discharged battery has frozen. In this case, you may neither charge the battery nor jump-start the vehicle. The service life of a thawed-out battery may be shorter. The starting characteristics can be impaired, particularly at low temperatures. Have the thawed-out battery checked at a qualified specialist workshop.

All vehicles:
Do not start the vehicle using a rapid charging device. If your vehicle’s battery is discharged, the engine can be jump-started from another vehicle or from a second battery using jumper cables. Observe the following points:

• The battery is not accessible in all vehicles. If the other vehicle’s battery is not accessible, jump-start the vehicle using a second battery or a jump-starting device.
• You may only jump-start the vehicle when the engine and exhaust system are cold.
• Keep away from fire and open flames.
• Do not start the engine if the battery is frozen. Let the battery thaw first.
• All vehicles except Mercedes-AMG vehicles: do not start the engine if the battery is frozen. Let the battery thaw first.
• Only jump-start from batteries with a 12 V voltage rating.
• Only use jumper cables that have a sufficient cross-section and insulated terminal clamps.
• Do not lean over the battery.
• If the battery is fully discharged, leave the battery that is being used to jump-start connected for a few minutes before attempting to start. This charges the battery slightly.
• Make sure that the two vehicles do not touch.
  Make sure that:
• the jumper cables are not damaged.
• when the jumper cables are connected to the battery, uninsulated sections of the terminal clamp do not come into contact with other metal sections.
• the jumper cables cannot come into contact with parts that can move when the engine is running, such as the V-belt pulley or the fan.
• Secure the vehicle by applying the electric parking brake.
• Shift the transmission to position P.
• Make sure that the ignition is switched off (Y page 151). All indicator lamps in the instrument cluster must be off. When using the SmartKey, turn the SmartKey to position 0 in the ignition
  lock and remove it (Y page 151).
• Switch off all electrical consumers, e.g. rear window defroster, lighting, etc.
• Open the hood.
  Example: ground point cover
• Turn the fasteners 1 by 4 one turn and remove.
• Remove the cover whilst pressing down on cap 2 of the washer fluid reservoir.
  Position number 8 identifies the charged battery of the other vehicle or an equivalent jump-starting device.
• Slide cover 7 of positive terminal 3 in the direction of the arrow.
• Connect positive terminal 3 on your vehicle to positive terminal 4 of donor battery 8 using the jumper cable. Always begin with positive terminal = on your own vehicle first.
• Start the engine of the donor vehicle and run it at idling speed.
• Connect negative terminal 5 of donor battery 8 to ground point 6 of your vehicle using the jumper cable, connecting the jumper cable to donor battery 8 first.
• Start the engine.
• Before disconnecting the jumper cables, let the engine run for several minutes.
• First, remove the jumper cables from ground point 3 and negative terminal 4, then from positive clamp = and positive terminal ?. Begin each time at the contacts on your own vehicle first.
• Close cover 7 of positive clamp 3 after removing the jumper cables.
• Replace the ground point cover. Make sure all mountings for the fasteners are positioned precisely beneath the corresponding recesses in the cover.
• Press fasteners 1 into the mountings until they engage.
• Have the battery checked at a qualified specialist workshop.
  Jump-starting is not considered to be a normal operating condition.
  Jumper cables and further information regarding jump-starting can be obtained at any qualified specialst workshop.

Operation

Useful information
This Operator’s Manual describes all models and all standard and optional equipment of your vehicle available at the time of publication of the Operator’s Manual. Country-specific differences are possible. Please note that your vehicle may not be equipped with all features described. This also applies to safety-related systems and functions.
Read the information on qualified specialist workshops (page 26).

Important safety notes

WARNING
If wheels and tires of the wrong size are used, the wheel brakes or suspension components may be damaged. There is a risk of an acci-dent.
Always replace wheels and tires with those that fulfill the specifications of the original part.
When replacing wheels, make sure to use the correct:

• designation
• model
  When replacing tires, make sure to use the correct:
• designation
• manufacturer
• model

Accessories that are not approved for your vehicle by Mercedes-Benz or are not being used correctly can impair the operating safety.
Before purchasing and using non-approved accessories, visit a qualified specialist work-shop and inquire about:

• suitability
• legal stipulations
• factory recommendations
  Information on the sizes and types of wheels and tires for your vehicle can be found under “Wheel/tire combinations” (Y page 388). Information on tire pressure can be found:
• on the vehicle’s Tire and Loading Information placard on the B-pillar (Y page 372) Ron the tire pressure label on the fuel filler flap (page 168)
  Runder “Tire pressure” (page 365)

Information on driving
Check the tire pressure when the vehicle is heavily laden and adjust prior to a trip.
While driving, pay attention to vibrations, noises and unusual handling characteristics, e.g. pulling to one side. This may indicate that the wheels or tires are damaged. If you sus-pect that a tire is defective, reduce your speed immediately. Stop the vehicle as soon as possible to check the wheels and tires for damage. Hidden tire damage could also be causing the unusual handling characteristics. If you find no signs of damage, have the tires and wheels checked at a qualified specialist workshop.
When parking your vehicle, make sure that the tires do not get deformed by the curb other obstacles. If it is necessary to drive over curbs, speed humps or similar elevations, try to do so slowly and at an obtuse angle. Otherwise, the tires, particularly the sidewalls, may be damaged.

Regular checking of wheels and tires

WARNING
Damaged tires can cause tire inflation pres-sure loss. As a result, you could lose control of your vehicle. There is a risk of accident.
Check the tires regularly for signs of damage and replace any damaged tires immediately.

Regularly check the wheels and tires of your vehicle for damage at least once a month, as well as after driving off-road or on rough roads. Damaged wheels can cause a loss of tire pressure. Pay particular attention to dam-age such as:

• cuts in the tires
• punctures
• tears in the tires
• bulges on tires
• deformation or severe corrosion on wheels

Regularly check the tire tread depth and the condition of the tread across the whole width of the tire (Y page 363). If necessary, turn the front wheels to full lock in order to inspect the inner side of the tire surface.
All wheels must have a valve cap to protect the valve against dirt and moisture. Do not mount anything onto the valve other than the standard valve cap or other valve caps approved by Mercedes-Benz for your vehicle. Do not use any other valve caps or systems, e.g. tire pressure monitoring systems.
Regularly check the pressure of all the tires particularly prior to long trips. Adjust the tire pressure as necessary (Y page 365).

The service life of tires depends, among other things, on the following factors:

• Driving style
• Tire pressure
• Distance covered
