Securing the vehicle on level ground
X
On level ground: place chocks or oth er
su itabl eitem sunder the front and rea rof
the whee lthat is diagonally opposite the
whee lyou wish to change. Securing the vehicle on slight downhill gradients
X On ligh tdownhill gradients: place
chocks or other suitabl eitems in front of
the wheels of the front and rear axle.
Raisin gthe vehicle G
WARNING
If you do not positio nthe jac kcorrectly at the
appropriate jackin gpoint of the vehicle, the
jac kc ould 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 jackin gpoint of the vehicle.
! AMG vehicles equipped with the
"Minispare" emergency spare wheel:
Use the "Minispare" emergency spare wheel
only on th erear axle.Ift he
"Minispare" emergenc yspare wheel is
mounted on the front axle, it could damage
the brak esystem.
If at yre on the front axle is faulty, an intact
whee lfrom th erear axle must first be
replaced by the "Minispare" emergency
spare wheel. The faulty tyr eonthe front
axl es hould then be replaced by the intact
tyr efrom th erear axle.
Be sure to observ ethe instruction label on
the "Minispare" emergenc yspare wheel.
The following must be observed when raising
the vehicle:
R to raise the vehicle, only use the vehicle-
specifi cjack that has been tested and
approved by Mercedes-Benz .Ifthe jac kis
used incorrectly, it could tip over while the
vehicle is raised.
R the jack is designed only to raise and hold
the vehicle for ashort tim ewhile awheel
is being changed. It is not suited for per-
forming maintenance wor kunder the vehi-
cle.
R avoid changing the wheel on uphil land
downhil lslopes.
R before raising the vehicle, secure it from
rolling away by applying the parkin gbrake
and inserting whee lchocks. Never disen-
gage the parkin gbrake whil ethe vehicle is
raised.
R the jac kmust be placed on afirm ,flat and
non-slip surface. On aloose surface, a
large, load-bearing underlay must be used.
On aslippery surface, anon-slip underlay
must be used, e.g. rubber mats.
R do not use wooden block sorsimilar
objects as ajack underlay .Otherwi se,the
jack wil lnot be able to achiev eits load-
bearing capacity due to the restricted
height.
R mak esure that the distanc ebetween the
underside of the tyr es andthe grou nddoes
not exceed 3cm. 406

WARNING
Oiled or greased wheel bolt sordamaged
wheel bolts/hub threads can cause the wheel
bolts to com eloose .Asa result,you could
lose awheel while driving. There is arisk of
accident.
Never oil or grease wheel bolts. In the event
of damage to the threads, contact aqualified
specialist workshop immediately .Have the
damaged wheel bolts or hub threads
replaced/renewed. Do not continue driving. G
WARNING
If you tighten the wheel bolts or wheel nuts
when the vehicle is raised, the jac kcould tip
over .There is arisk of injury.
Only tighten the wheel bolts or wheel nuts
when the vehicle is on the ground.
Always pay attention to the instructions and
safety notices in "Changing awheel"
(Y page 404).
Only use wheel bolts that hav ebeen designed
for the wheel and the vehicle. For safet yrea-
sons, Mercedes-Benz recommends that you
only use wheel bolts which have been approved for Mercedes-Benz vehicles and the
respec
tivewheel.
! Always use wheel bolts ;to fit the col-
lapsibl eemergency spare wheel. Using
othe rwheel bolts to fit the collapsible
emergenc yspare wheel could damage the

Do not mix such fuels with diesel fuel and
do not use any special additives. This can

Infor mation on refuelling (Y page 175).
Low outside temperatures
In winter months, diesel fuel with an improved
cold flow quality is available. In Europe, the
EN 590 standard defines various climate-
dependent temperature categories. Malfunc-
tions can be avoide dbyrefuelling with diesel
fuel that corresponds to the climatic specifi-
cations outlined in EN 590. At unusually low
outside temperatures, it is possible that the
flow characteristics of the diesel fuel could be
insufficient .Accordingly, dies elfue lfrom
warmer areas may not be suitabl efor opera-
tion in colder climat icconditions.
i Further informatio noncountry-specific
fuel properties can be obtained from oil
companies, e.g. at filling stations.
Flow imp rovers
To improve the low-temperatur eresistanc eof
diesel fuel, aflow improver can be attached.
The effec tiveness of aflow improver is not
guaranteed for every fuel.
Only use flow improvers tested and approved
by Mercedes-Benz. Durin guse, please
observe the information on operation.
Correc tdosage and sufficien tmixing are deci-
sive in improving low-temperature resistance
with the flow improver. Overdosage can
potentially even decrease low-temperature
resistanc eand must therefor ebeavoided.
Follo wthe manufacturer's guidelines on dos-
age.
Mix the additive int othe diesel in good time,
before the flo wcharacteristic softhe diesel
becom einsufficie nt.O therwise, malfunctions
can only be rectified by heating the entire fuel
system, e.g. by parking in aheated garage. 426

Engine oil viscosity Viscosit
ydescribes the flow characteristics
of afluid. If an engine oil has ahigh viscosity
rating, it flows slowly ;the lower the viscosity,
the faster it flows.
Engin eoil selection is based on the respective
outside temperatures and in accordance with
the SAE classification (viscosity). The table
shows you which SAE classifications are to be
used. The low-temperature properties of
engine oils can be significantly impaired dur-
ing operation due to, for example, ageing or
soot and fuel accretion .Itistherefore
strongly recommended to observe regular oil
changes usin ganapproved engine oil with the
appropriate SAE classification. Brake fluid
G
WARNING
Over aperiod of time, the brak efluid absorbs
moisture from the air; This lowers its boiling
point.
If the boiling point of the brake fluid is too low,
vapour pocket smay form in the brake system
when the brakes are applied hard (e.g. when
driving downhill). This impairs braking effi-
ciency.
You shoul dhave the brake fluid renewed at
regular intervals. The brake fluid change inter-
vals can be found in the Service Booklet.
Only use brake fluid approved by Mercedes-
Benz according to MB Approval 331.0.
Information about approved brake fluid can
be obtained at any qualified specialist work-
sho poront he Internet at

WARNING
Antifreeze is highly flammable. Fire, naked
flames and smoking are prohibited when han-
dling antifreeze.
If antifreeze comes into contact with hot
