Uniform Tire Quality Grading Standards: a
uniform standard tograde thequ ality of tires
with rega rd totread quality, tire traction and
te mp erature characteristics. The quality grading
assessment is made bythe manufacturer follow‐
ing specifications from theU. S. go vernment. The
qu ality grade of a tire is imprinted on the side
wa ll of the tire.
Re commended tire pressure :th ere commen‐
ded tire pressure is the tire pressure specified
fo rth e tires mounted totheve hicle at thefa c‐
to ry.
The tire and information table conta insthere c‐
ommended tire pressures for cold tires, the max‐
imum permissible load and the maximum per‐
missible vehicle speed.
The tire pressure table conta insthere commen‐
ded tire pressures for cold tires under various
operating conditions, i.e. loading and/or speed
of theve 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): the GAWR
is the maximum permissible axle load. The
actual load on an axle must ne verexc eed the
gros s axle weight rating. The gross axle
weight
ra ti

ng can be found on theve hicle identification
plate 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 comprises thewe ight of theve hicle
including fuel, tools, the spare wheel, accesso‐
ri es ins talled, occupants, luggage and the trailer
dr aw bar nose weight, if applicable. The gross
ve hicle weight must not exceed the gross vehicle
we ight rating GVWR as specified on theve hicle
identification plate on the B‑pillar on the driver's
side.
GV WR (Gross Vehicle Weight Rating): the
GV WR is the maximum permitted gross weight of
the 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 grossve hicle 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 the curb weight
of theve hicle, thewe ight of the accessori es,the
maximum load and thewe ight of optional equip‐
ment ins talled at thefa ctor y.
Kilopascal (kPa): metric unitfor tire pressure .
6.9 kPa cor responds to1 psi. Ano ther unit for
tire pressure is bar.
10 0 ki
lopascal (kPa) equals
1 bar.
Load index: in additiontothe load-bearing
index, the load index may also be imprinted on
th e side wall of the tire. This specifies the load-
bearing capacity of the tire 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

Thewear patte rns on the front and rear wheels
dif fer:
RFr ont wheels wear more on the shoulder of
th e tire
RRe ar wheels wear more in the center of the
tire
On vehicles that ha vethe same size front and
re ar wheels, rotat eth e wheels according tothe
inter vals in the tire manufacturer's warranty
book in your vehicle documents. If this is not
av ailable, rotate the tires every
3,000 to6,000 miles (5,000to10,000 km),
depending on thewe ar. Ensure that the direction
of rotation is maintained.
It is impe rative toobser vethe instructions and
saf etyno tes on "Wheel change" when doing so.
Note s onstoring wheels
RAf terre moving wheels, store them in a cool,
dry and preferably dark place.
RPr otect the tires from conta ct withoil, grease
or fuel.

Notes on brake fluid
Obser vethe no tes on operating fluids
(→page 387).
0071 WARNING Risk of an accident due to
va por poc kets form ing in the brake sys‐
te m
The brake fluid constantly absorbs moisture
from the air. This lo wersthe boiling point of
th e brake fluid. Ifth e boiling point is too lo w,
va por poc kets may form inthe brake sy stem
when the brakes are applied hard.
This causes the braking ef fect to be
impaired.
00BBHa ve the brake fluid rene we d at the
specified inter vals.
Ha ve the brake fluid regularly changed at a quali‐
fi ed specialist workshop.
Only use brake fluid appr ovedby Mercedes-Benz
according toMB-F reigabe or MB-Appr oval 33 1.0.
