Jump-starting
For the jump-starting procedure, use only the jump-starting connection point, consisting of apositive terminal and a ground point, in the engine compartment.
GWARNING
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.
GWARNING
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 ven-
tilation while charging and jump-starting. Do not lean over a battery.
GWARNING
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.
R Make sure that the positive terminal of a connected battery does not come into contact with
vehicle parts.
R Never place metal objects or tools on a battery.
R It is important that you observe the described order of the battery terminals when connecting
and disconnecting a battery.
R When jump-starting, make sure that the battery poles with identical polarity are connected.
R It is particularly important to observe the described order when connecting and disconnecting
the jumper cables.
R Never connect or disconnect the battery terminals while the engine is running.
GWARNING
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.
!Vehicles with a gasoline engine: avoid repeated and lengthy starting attempts. Other-
wise, the catalytic converter could be damaged by 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 jump-start the vehicle nor charge the battery.
Once the battery has thawed out, its service life may be dramatically reduced.
The starting characteristics can be impaired, particularly at low temperatures.
Have the thawed-out battery checked at a qualified specialist workshop.

The jump-starting connection point consists of poles;and =.
X Lift up cover :of positive terminal ;in the direction of the arrow.
X Connect positive terminal ;on your vehicle to positive terminal ?of donor battery B
using the jumper cable. beginning with your own battery.
X Start the engine of the donor vehicle and run it at idling speed.
X Connect negative terminal Aof donor battery Bto ground point =of your vehicle using
the jumper cable, connecting the jumper cable to donor battery Bfirst.
X Start the engine.
X First, remove the jumper cables from ground point =and negative terminal A, then from
positive clamp ;and positive terminal ?. Each time beginning with your vehicle's battery.
X Have the battery checked at a qualified specialist workshop.
iJump-starting is not considered to be a normal operating condition.
iJumper cables and further information regarding jump-starting can be obtained at any
qualified specialist workshop.
Towing and tow-starting
Important safety notes
GWARNING
Functions relevant to safety are restricted or
no longer available if:
R the engine is not running.
R the brake system or the power steering is
malfunctioning.
R there is a malfunction in the voltage supply
or the vehicle's electrical system.
If your vehicle is being towed, much more
force may be necessary to steer or brake.
There is a risk of an accident.
In such cases, use a tow bar. Before towing,
make sure that the steering moves freely.
GWARNING
When towing or tow-starting another vehicle
and its weight is greater than the permissible gross weight of your vehicle, the:
R the towing eye could detach itself
R the vehicle/trailer combination could roll-over.
There is a risk of an accident.
When towing or tow-starting another vehicle,
its weight should not be greater than the per- missible gross weight of your vehicle.
!If DISTRONIC PLUS or the HOLD function
is activated, the vehicle brakes automati-
cally in certain situations. To prevent dam-
age to the vehicle, deactivate DISTRONIC
PLUS and the HOLD function in the follow- ing or other similar situations:
R when towing the vehicle
R in the car wash
!The vehicle can be towed a maximum of
30 miles (50km). The towing speed of
30 mph (50 km/h) must not be exceeded.
If the vehicle has to be towed more than
30 miles (50km), the entire vehicle must be
raised and transported.
!Only secure the tow cable or tow bar to
the towing eyes. You could otherwise dam-
age the vehicle.
!Do not tow with sling-type equipment.
This could damage the vehicle.
!Do not use the towing eyes for recovery
purposes as this could damage the vehicle.
If in doubt, recover the vehicle with a crane.

iThe coolant is checked with every main-
tenance interval at a qualified specialist workshop.
The engine cooling system is filled with cool-
ant at the factory which contains antifreeze/
corrosion inhibitor that ensures protection
down to approximately -35 ‡ (-37 †).
Your vehicle has a range of aluminum com-
ponents. Aluminum components in the
engine make it necessary to use antifreeze/
corrosion inhibitor that has been specifically
formulated to protect the aluminum parts.
Failure to use such anticorrosion/antifreeze
coolant will result in a significantly shortened service life.
The coolant must be used throughout the year
in order to maintain the necessary corrosion
protection and to provide protection from
overheating. In the Maintenance Booklet, you
can find information on the intervals forrenewal.
The renewal interval is determined by the
coolant type and the engine cooling system
design. The renewal interval in the Mainte-
nance Booklet is only valid if the coolant is
renewed or added to with Mercedes-Benz
approved products. Therefore, only use MB
326.0 antifreeze/corrosion inhibitor or
another Mercedes-Benz approved product of the same specification.
Information on other products with the same
specifications that are approved by
Mercedes-Benz can be obtained at an author- ized Mercedes-Benz Center or on the Internet
at http://bevo.mercedes-benz.com .
If the coolant level is too low, MB 325.0 anti-
freeze/corrosion inhibitor should be added.
Have the engine cooling system checked for
possible leaks.Capacity

Windshield/headlamp cleaning sys- tem
Important safety notes
GWARNING
Windshield washer concentrate could ignite if it comes into contact with hot engine compo-
nents or the exhaust system. There is a risk of
fire and injury.
Make sure that no windshield washer con-
centrate is spilled next to the filler neck.
!Only use washer fluid that is suitable for
plastic lamp lenses, e.g. MB SummerFit or
MB WinterFit. Unsuitable washer fluid
could damage the plastic lenses of theheadlamps.
!Do not add distilled or de-ionized water to
the washer fluid container. Otherwise, the
level sensor may be damaged.
!Only MB SummerFit and MB WinterFit
washer fluid should be mixed together. The spray nozzles may otherwise becomeblocked.
