R "Light load": light load tires
R "C": commercial tires Information on definitions (tires and load‐
ing)
Ti re stru ctu reand characteristics: describes
th e number of la yers or the number of rubber-
coated la yers inthe tire tread and the tire wall.
These are made of steel, nylon, pol yester and
ot her materials.
Bar: metric unit for tire pressu re.
14 .5038 pounds per square inch (psi) and
10 0 kilopascals (kPa) are the equivalent of 1 bar.
DOT (Department of Transportation): DOT
mar ked tires fulfill there qu irements of the
U. S. Depa rtment of Transpor tatio n.
Av erage weight of vehicle occupants: the
number of occupants for which theve hicle is
designed multiplied by150 lbs (68 kg).
Un iform Tire Quality Grading Standards: a uni‐
fo rm standard tograde thequ ality of tires with
re ga rdsto tread quality, tire traction and temp er‐
ature characteristics. The quality grading assess‐
ment is made bythe manufacturer in accordance
with test specifications of theU. S. go vernment.
The quality grade of a tire is imprinted on the
side wall of the tire.
Re commended tire pressu re:there commen‐
ded tire pressure is the pressure specified forthe
tires ins talled on theve hicle at thefa ctor y.
The Tire and Loading In form ation placard con‐
ta ins there commended tire pressures for cold
tires, the maximum permissible load and the
maximum permissible vehicle speed.
The tire pressure table con tains there commen‐
ded tire pressures for cold tires under various
operating conditions, i.e. load and/or speed of
th eve hicle.
Increased vehicle weight due tooptional
equipment: the combined weight of all standard
and optional equipment available forth eve hicle,
re ga rdless of whe ther it is actually ins talled on
th eve hicle or not.
Rim: the part of the wheel on which the tire is
ins talled.
GA WR (Gross Axle Weight Rating): GAWR is the
gross axle weight rating. The actual load on an
axle mu stneverexc eed the Gross Axle Weight Ra
ting. You can find the Gross Axle Weight Rating
on the B-pillar on the driver's side.
Speed rating: the speed rating is pa rtof the tire
identification. It specifies the speed range for
which a tire is appr oved.
GV W (Gross Vehicle Weight): the Gross Vehicle
We ight includes thewe ight of theve hicle includ‐
ing fuel, tools, the spare wheel, accessories
ins talled, occupants, luggage and the trailer
dr aw bar nose weight if applicable. The Gross Vehi‐
cle Weight must ne verexc eed the Gross Vehicle
We ight Rating (GVWR) specified on the B-pillar on
th e driver's side.
GV WR (Gross Vehicle Weight Rating): the
GV WR is the maximum permitted gross weight of
th e fully laden vehicle (weight of theve hicle
including all accessories, occupants, fuel, lug‐
ga ge and the trailer dr awbar nose weight if appli‐
cable). The Gross Vehicle Weight Rating is speci‐
fi ed on theve hicle identification plate on the B-
pillar on the driver's side.
Maximum weight of the laden vehicle: the
maximum weight is the sum of theve hicle's curb
we ight, weight of the accessories, maximum load
and thewe ight of thefa ctory ins talled optional
equipment.
Kilopascal (kPa): metric unitfor tire pressu re.
6.9 kPa are the equivalent of 1 psi. Ano ther unit
fo r tire pressu reis bar. 100 kilopascals (kPa) are
th e equivalent of 1 bar.
Load index: in additiontothe load-bearing index,
th e load index may also be imprinted on the side‐
wa ll of the tire. This specifies the load-bearing
capacity more precisel y.
Curb weight: thewe ight of a vehicle with stand‐
ard equipment including the maximum capacity
of fuel, oil and coolant. It also includes the air-
conditioning sy stem and optional equipment if
th ese are ins talled on theve hicle, but does not
include passengers or luggage.
Maximum tire load: the maximum tire load is
th e maximum permissible weight in kilog rams or
lbs for which a tire is appro ved.
Maximum permissible tire pressure: maximum
permissible tire pressure for one tire.
Maximum load on one tire: maximum load on
one tire. This is calculated bydividing the maxi‐
mum axle load for one axle bytwo.

additional benefits, e.g. if there is a risk of hydro‐
planing. You will on lyga in these benefits if the
cor rect direction of rotation is obser ved.
An ar rowonthe side wall of the tire indicates its

vethefo llowing when storing wheels:
R Wheels that ha vebeen remo ved should be
st ored in a cool, dry and, if possible, dark
place.
R Protect the tires from oil, grease and fuel. Overview of

clogging. Deposits may also
form onthe fuel
injec tor.This may reduce the engine output.
Unburned fuel can get into the oil pan. This
causes the engine oil le velto rise. This can
cause engine mechanical damage.
Obser vethefo llowing points to avoid damage
and reducing the engine output: #
Fill up with fuels with bio-diesel content
of 5% (ULSD) or less, whene ver possi‐
ble. #
Regular lych eck your engine oil le vel if
yo u use B20 fuels on a regular basis. #
Strictly follow the oil change inter vals
qu oted in the instrument clus ter and
within your Main tenance Bookl et. #
Use only engine oils and filters
appr ovedfo r use in your vehicle. #
Ifyo u do not plan todrive your vehicle
fo r se veralwe eks, comple tely fill the
fuel tank in ad vance wi thULSD fuel. Fo
r more information, consult thega sst ation
st aff. The identification of fuels with bio-diesel
con tent (ULSD or B20) must be clear. If the iden‐
tification is not clear, do not refuel. Do not refuel
with any fuels that ha venot been appr ovedfor

DEF consum ption and filling capacity
DEF consum ption
Like fuel consum ption, DEF consum ption is highly
dependent upon driving style and operating con‐
ditions. DEF consum ption is usually within a
ra nge of 0 and 10% of the fuel consum ption. If
necessar y,DEF mu stbe refilled in acco rdance
with the instructions when there fill message is
displa yed in the instrument clus ter.This may also
be necessary between the scheduled mainte‐

The vehicle must be operated with DEF if the
ex haust gas af tertre atment sy stem is tofunction

If yo u operate theve hicle without DEF or with
emissions-rele vant malfunctions, the legal MOT
appr oval is in validated. The vehicle could be pro‐
hibited from public road use byan of ficial ordi‐
nance.
It may be improper or punishable in some coun‐
tries tooperate a vehicle that uses no DEF or one
th at does not comply with the specifications of
th ese operating instructions.
Engine management monitors theex haust gas
af te rtre atment components for compliance with
emissions la wsand regulations. If you attem ptto
operate theve hicle without DEF, with diluted DEF
or with a dif fere nt reducing agent, this will be
de tected bythe engine management sy stem.
Other emissions- releva nt malfunctions, e.g.
me tering malfunctions or sensor er rors, are also
de tected and log ged. The engine management sy
stem subsequently

a wa rning message.
Therefore add DEF tank regular lyduring vehicle

SA E classi fication (viscosity) of the
engine oil If
th eSA E classi fication (viscosity) of the
engine oil added is not suitable for prolonged
low outside temp eratures, it may cause
engine damage.
The temp erature readings of theSA E classi fi‐
cation are al ways based on fresh oil. Engine
oil ages when driving as a result of soot and
fuel residue. The characteristics of engine oil
de teriorate significantly at low outside tem‐
peratures. #
Use an engine oil of the appropriate SAE
classi fication at low outside temp era‐
tures. #
Use oil for all-year-round operation. The
temp erature readings of theSA E classi fica‐
tion are al ways based on fresh oil. The temp era‐
ture characteristics of the engine oil, especially at
low outside temp eratures, can de teriorate signifi‐
cantly due toaging when driving.
Therefore, Mercedes-Benz recommends that you
ch ange the engine oil before thest art of the cold
season. Only use an appr oved engine oil in the
prescribed SAE classi fication forth is purpose. The viscosity indicates
theflow characteristics of
a fluid. With rega rd toengine oil, a high viscosity
is synonymous with thick liquid and a low viscos‐
ity with thin liquid. Depending on the outside
te mp eratures, select the engine oil according to
th eSA E classi fication (viscosity). The table sho ws
th eSA E classi fications tobe used. The low tem‐
perature characteristics of engine oils can de teri‐
orate significantly during operation due toaging
and soot and fuel acc retion, forex ample. A regu‐
lar oil change with an appr oved engine oil in the
appropriate SAE classi fication is therefore
