Checking engine oil level
E 320 shown
1Oil dipstick
2Oil filler cap
To check the engine oil level, park vehicle on level
ground, with engine at normal operational temperature.
Check engine oil level approximately 5 minutes after
stopping the engine, allowing for the oil to return to the
oil pan.The engine oil level can be checked by either the oil
dipstick or via the multifunction display in the
instrument cluster.
Wipe oil dipstick clean prior to checking the engine oil
level. Fully insert dipstick in tube, and remove after
three seconds to obtain accurate reading.
The oil level must be between the lower
mark (min) and the upper mark (max)
on the oil dipstick.
Fill quantity between upper and lower dipstick marking
level is approximately 2.1 US qt (2.0 l).
Do not overfill the engine.
Excessive oil must be drained or siphoned. It could
cause damage to engine and catalytic converter not
covered by the Mercedes-Benz Limited Warranty.
See malfunction and warning messages on page 258 if
an engine oil level display appears on the multifunction
display when the engine is running.
Note:
See page 117 for engine oil level indicator.

The transmission has a permanent fill of automatic
transmission fluid.
Regular automatic transmission fluid level checks and
changes are not required. For this reason the dipstick is
omitted.
If you notice fluid leaks or gear shifting malfunctions,
have your authorized Mercedes-Benz Center check the
transmission fluid level.Coolant level
To check the coolant level, the vehicle must be parked
on level ground and the engine stopped.
Check coolant level only when coolant is cold.
The coolant level should reach the black top part of the
reservoir.

284 Battery

must not leak acid when upside down for at least
15 minutes. Your authorized Mercedes-Benz Center can
provide such a special battery.
The service life of the battery is dependent on its
condition of charge. The battery should always be kept
sufficiently charged, in order to last an optimum length
of time.
Therefore, we strongly recommend that you have the
battery charge checked frequently, and corrected if
necessary, especially if you use the vehicle less than
approximately 200 miles (300 km) per month,
mostly for short distance trips, or if it is not used for
long periods of time.
Only charge a battery with a battery charger after the
battery has been disconnected from the vehicle’s
electrical circuit.
Always disconnect the battery negative lead first and
connect last.
When removing and connecting the battery, always
make sure that all electrical consumers are off and the
electronic key is in steering lock position 0. The battery,
its filler caps, the vent tube and the opposite plug must
always be securely installed when the vehicle in operation. During removal and installation always
protect the disconnected battery positive (+) terminal
with the cover attached to the battery.
While the engine is running the battery terminal clamps
must not be loosened or detached, otherwise the
generator and other electronic components would be
damaged.
Note:
After reconnecting the battery also resynchronize the
front seat head restraints, the express feature of the
power windows, and the electronic stability program
(ESP), see page 46, 156 and 229.
Battery recycling
Batteries contain material that can harm the
environment with improper disposal.
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.

287 Jump starting

grounded negative (–) terminal of the charged
battery and the final connection to the negative (–)
under hood terminal (3) of the disabled vehicle.
Important!
5. Start engine of the vehicle with the charged battery
and run at high idle. Make sure the cables are not
on or near pulleys, fans, or other parts that move
when the engine is started. Allow the discharged
battery to charge for a few minutes. Start engine of
the disabled vehicle in the usual manner.6. After the engine has started, remove jumper cables
by exactly reversing the above installation
sequence, starting with the last connection made
first. When removing each clamp, make sure that it
does not touch any other metal while the other end
is still attached.
Note:
If engine does not run after several unsuccessful
starting attempts, have it checked at the nearest
authorized Mercedes-Benz Center.
Excessive unburned fuel may damage the catalytic
converter.

heat transfer capability of the solution. Therefore, do not
use more than this amount of anticorrosion / antifreeze.
If the coolant level is low, water and MB anticorrosion /
antifreeze should be used to bring it up to the proper
level (have cooling system checked for signs of leakage).
The water in the cooling system must meet minimum
requirements, which are usually satisfied by normal
drinking water. If your are not sure about the water
quality, consult your authorized Mercedes-Benz Center.
Anticorrosion / antifreeze
Your vehicle contains a number of aluminum parts. The
use of aluminum components in motor vehicle engines
necessitates that anticorrosion / antifreeze coolant used
in such engines be specifically formulated to protect the
aluminum parts. (Failure to use such anticorrosion /
antifreeze coolant will result in a significantly
shortened service life.)
Therefore the following product is strongly
recommended for use in your car: Mercedes-Benz
Anticorrosion / Antifreeze Agent.Before the start of the winter season (or once a year in
the hot southern regions), you should have the
anticorrosion / antifreeze concentration checked. The
coolant is also regularly checked each time you bring
your vehicle to your authorized Mercedes-Benz Center
for service.
