Adding engine oil
!Use only engine oils and oil filters that are
approved for vehiclesw ithaservice system. A
list of the engine oils and oil filters that have
been tested and approved in accordance with
Mercedes-Benz Specifications for Service
Products is available at any authorized
Mercedes-Benz Center.
The following cause engine failure or damage
to the exhaust system:
RUse of engine oils and oil filters that have
not been expressly approved for the service
system
RReplacement of engine oil and oil filter after
the replacement interval specifiedbyt he
service system has expired
RUse of engine oil additives
!Do not add too much oil. If the oil level is
above the "max" mark on the dipstick, too
much oil has been added. This can leadt o
damage to the engine or the catalytic con-
verter. Have excess oil siphoned off.
HEnvironmental note
When adding oil, take care not to spilla ny. If
oil enters the soil or waterways ,itisharmful to
the environment.
Example: engine oil cap
XTurn cap :counter-clockwise and remove it.
XAdd the amount of engine oil required.
Observe the specifications in the on-board com-
puter when doing so or fill carefully to the max-
imum mark on the oil dipstick.
The difference betweent he minimum mark and
the maximum mark on the oil dipstick is approx-
imatel y2.1 US qt (2.0 l).
XReplace cap :on the fille rneck and tighten
clockwise.
Ensur ethat the cap locks into place securely.

Points to remember
The specified maintenance interval takes only
the normal operation of the vehiclei nto
account. Under arduous operating conditions or
increased loadont he vehicle, maintenance
work must be carrie dout more frequently, for
example:
Rregular city driving with frequent intermediate
stops
Rif the vehicleisp rimarily usedtotravel short
distances
Ruse in mountainous terrainoronp oor road
surfaces
Rif the engine is often left idling for long periods
Under these or similar conditions, have ,for
example, the air filter, engine oil and oil filter
replaced or changed more frequently. Under
arduous operating conditions, the tires must be
checked more often. Further information can be obtained at aqualified specialist workshop, e.g.
an authorized Mercedes-Benz Center.
Care
General notes
!
For cleaning you rvehicle, do not use any of
the following:
Rdry, roug horhard cloths
Rabrasive cleaning agents
Rsolvents
Rcleaning agents containing solvents
Do not scrub.
Do not touch the surfaces or protective films
with hard objects, e.g. aring or ice scraper.
You coul dotherwise scratch or damage the
surfaces and protective film.
!Do not park you rvehiclef oralong period of
time directly after cleaning, particularly after
cleaning the wheelr im with wheelcleaner.
Wheelc leaner can leadtot he increased cor-
rosionoft he brake discs and pads. Therefore,
drive for afew minutes after cleaning. By
heating up the brakes ,the brake discs and
padsd ry. The vehiclec an then be parked for a
long period of time.

GWARNING
Braking efficiency is reduced after washing
the vehicle. There is arisk of an accident.
After the vehicleh as been washed, brake
carefully while paying attention to the traffic
conditions until full braking power is restored.
!When DISTRONIC PLUS or the HOLD func-
tion is activated, the vehicleb rakes automat-

Maintenance and care

!On vehicles equipped withatire pressure
monitor, electronic componentsa re located
in the wheel.
Tire-mounting tools should not be used near
the valve. This could damage the electronic
components.
Only have tires changed at aqualified spe-
cialist workshop.
Alwayso bserve the instructionsa nd safety
notes under "Installing awheel" (
Ypage 270).
The wear patterns on the front and rear tires
differ, depending on the operating conditions.
Rotate the wheels before aclear wear pattern
has formed on the tires. Front tires typically
wear more on the shoulders and the rear tires in the center.
On vehicles that have the same size front and
rear wheels, you can rotate the wheels accord-
ing to the intervals in the tire manufacturer's
warranty book in your vehicle documents. If no
warranty book is available, the tires should be
rotated every 3,000 to 6,000 miles (5,000 to
10,000 km). Depending on tire wear, this may
be required earlier. Do not change the direction
of wheel rotation.
Cleant he contact surfaces of the wheel and the
brake disc thoroughly every time awheel is rota-
ted. Check the tire pressure and reactivate the
tire pressure monitor if necessary (
Ypage 259).
Direction of rotation
Tires with aspecified direction of rotation have
additional benefits, e.g. if there is arisk of hydro-
planing. You will only gain these benefits if the
correct direction of rotation is observed.
An arrow on the sidewall of the tire indicates its
correct direction of rotation.
You may mount the spare wheel against the
direction of rotation. Adhere to the time restric-
tion on use as well as the speed limitation speci-
fied on the spare wheel.
Storing wheels
Store tires that are not being used in acool, dry
and preferably dark place. Protect the tires from
oil, grease, gasoline and diesel.
Mounting awheel
Preparing the vehicle
GWARNING
When you remove the spare wheel from the
spare wheel bracket, the vehicle’s weight dis-
tribution changes. If the vehicle is already
raised, the jack could tip over. There is arisk
of injury.
Remove the spare wheel from the spare wheel
bracket before lifting the vehicle.
XStop the vehicle on solid, non-slippery and
level ground.
XApply the parking brake.
XBring the front wheels into the straight-ahead

nally opposite the wheel you wish to change.
Raising the vehicle
GWARNING
If you do not position the jack correctly at the
appropriate jacking point of the vehicle, the
jack could tip over with the vehicle raised.
There is arisk of injury.
Only position the jack at the appropriate jack-
ing point of the vehicle. The base of the jack
must be positioned vertically, directly under
the jacking point of the vehicle.
!Only position the jack at the appropriate
