Observe the following when raising the vehi-cle:
RTo raise the vehicle, only use the vehicle-spe-cific jack that has been tested and approvedby Mercedes-Benz. If used incorrectly, thejack could tip over with the vehicle raised.
RThe jack is designed only to raise and hold thevehicle for a short time while a wheel is beingchanged. It must not be used for performingmaintenance work under the vehicle.
RAvoid changing the wheel on uphill and down-hill slopes.
RBefore raising the vehicle, secure it from roll-ing away by applying the parking brake andinserting wheel chocks. Do not disengage theparking brake while the vehicle is raised.
RThe jack must be placed on a firm, flat andnon-slip surface. On a loose surface, a large,flat, load-bearing underlay must be used. On aslippery surface, a non-slip underlay must beused, e.g. rubber mats.
RDo not use wooden blocks or similar objectsas a jack underlay. Otherwise, the jack will notbe able to achieve its load-bearing capacitydue to the restricted height.
RMake sure that the distance between theunderside of the tires and the ground does notexceed 1.2 in (3 cm).
RDo not place your hands or feet under theraised vehicle.
RDo not lie under the vehicle.
RDo not start the engine when the vehicle israised.

Comply with the important safety notes for ser-vice products when handling coolant(Ypage 358).
The coolant is a mixture of water and anti-freeze/corrosion inhibitor. It performs the fol-lowing tasks:
Ranti-corrosion protection
Rantifreeze protection
Rraising the boiling point
If the coolant has antifreeze protection down to-35 ‡ (-37 †), the boiling point of the coolantduring operation is approximately 266 ‡(130 †).
The antifreeze concentrate/corrosion inhibitorconcentration in the engine cooling systemshould:
Rbe at least 50%. This will protect the enginecooling system against freezing down toapproximately -35 ‡ (-37 †).
Rnot exceed 55% (antifreeze protection downto -49‡[-45 †]). Otherwise, heat will not bedissipated as effectively
Mercedes-Benz recommends an antifreeze/corrosion inhibitor concentrate in accordancewith MB Specifications for Service Products310.1.
iWhen the vehicle is first delivered, it is filledwith a coolant mixture that ensures adequateantifreeze and anti-corrosion protection.
iThe coolant is checked with every mainte-nance interval at a qualified specialist work-shop.

Important safety notes
GWARNING
Windshield washer concentrate is highly flam-
mable. If windshield washer concentrate gets
onto hot components of the engine or the
exhaust system, it can ignite. There is a risk of
fire and injury.
Make sure that windshield washer concen-
trate is not spilled in the vicinity of the filler
neck.
!Only use washer fluid which is suitable forlamp lenses, e.g. MB SummerFit or MB Win-terFit. Unsuitable washer fluid may damagethe lamp lenses of the headlamps.
!Only MB SummerFit and MB WinterFitwasher fluid should be mixed together. Thespray nozzles may otherwise becomeblocked.
Do not use distilled or de-ionized water. Other-wise, the level sensor may give a false reading.
When handling washer fluid, observe the impor-tant safety notes on service products(Ypage 358).
At temperatures above freezing:
XFill the washer fluid reservoir with a mixture ofwater and windshield washer fluid, e.g. MBSummerFit.
Add 1 part MB SummerFit to 100 parts water.
At temperatures below freezing:
XFill the washer fluid reservoir with a mixture ofwater and washer fluid, e.g. MB WinterFit.
For the correct mixing ratio refer to the infor-mation on the antifreeze reservoir.
iAdd windshield washer fluid, e.g. MB Sum-merFit or MB WinterFit, to the washer fluid allyear round.
