MERCEDES-BENZ EQE 2023 Owners Manual

(6): If your vehicle will be towing a trailer, load
from your trailer will be transferred to your
vehicle. Consult this manual to determine how
this reduces the available cargo and luggage
load capacity of your vehicle.\bNot all vehicles are permitted to tow a trailer.
Towing a trailer is only permitted if a trailer-
hitch is installed. Please consult an authorized
Mercedes-Benz dealer if you have any ques-
tions about towing a trailer with your vehicle.
Even if you have calculated the total load carefully,
you should still make sure that the maximum per-
missible gross weight and the maximum gross axle weight rating of your vehicle are not excee-ded. Details can be found on the vehicle identiN-
cation plate.

Tire Quality Grading
In accordance with the US Department of Trans-
portation\bs "Uniform Tire Quality Grading Stand-
ards", tire manufacturers are required to grade
their tires on the basis of the following three per-
formance factors:
1Tread wear grade2Traction grade3Temperature grade\bThe data shown in the illustration is example
data.\bThe classiNcation is not legally stipulated for
Canada, but it is generally stated.
Tread wear grade
The treadwear grade is a comparative rating based on the wear rate of the tire when testedunder controlled conditions on a speciNed govern-
ment test course. For example, a tire graded 150
would wear one and one-half (1=1/2=) times as
Wheels and tires381

well on the government course as a tire graded
100.
The relative performance of tires depends upon the actual conditions of their use, however, and
may depart signiNcantly from the norm due to var-
iations in driving habits, service practices and dif-
ferences in road characteristics and climate.
Traction grade&DANGER Risk of accident due to inade-
quate traction
The traction grade assigned to this tire is
based on straight-ahead braking traction
tests.
Always adapt your driving style and drive
at a speed to suit the prevailing traPc
and weather conditions.*NOTE Damage to the drivetrain from
wheelspinAvoid wheelspin.The traction grades, from highest to lowest, are
AA, A, B, and C. Those grades represent the tire\bs ability to stop on wet pavement as measured
under controlled conditions on speciNed govern-
ment test surfaces of asphalt and concrete. A tire
marked C may have poor traction performance.
Temperature grade&WARNING Risk of accident from tire over-
heating and tire failure
Excessive speed, underinOation, or excessive
loading, either separately or in combination, can cause excessive heat build-up and possi-
ble tire failure.
Observe the recommended tire pressure.Regularly check the pressure of all the
tires.Adjust the tire pressure, if necessary.
The temperature grades are A (the highest), B, and C, representing the tire\bs resistance to thegeneration of heat and its ability to dissipate heat
when tested under controlled conditions on a speciNed indoor laboratory test wheel. Sustained
high temperature can cause the material of the
tire to degenerate and reduce tire life, and exces-sive temperature can lead to sudden tire failure.
The grade C corresponds to a level of perform-
ance which all passenger car tires must meet
under the Federal Motor Safety Standard No. 109. Grades B and A represent higher levels of
performance on the laboratory test wheel than the minimum required by law.
DOT, Tire *dentiNcation Number (TIN)
US tire regulations stipulate that every tire manu-
facturer or retreader must imprint a TIN in or on
the side wall of each tire produced.
382Wheels and tires

\bThe data shown in the image is example data.
The TIN is a unique identiNcation number to iden-
tify tires and comprises the following:
= DOT (Department of Transportation): tire sym-
bol marks 1 indicating that the tire complies
with the requirements of the US Department of Transportation.
= Manufacturer identiNcation code: manufac-
turer identiNcation code 2 contains details of
the tire manufacturer. New tires have a code
with two symbols. Retreaded tires have a code
with four symbols. Further information on
retreaded tires (  page 388).
= Tire size: identiNer 3 describes the tire size.
= Tire type code: tire type code 4 can be used
by the manufacturer as a code to describe
speciNc characteristics of the tire.
= Manufacturing date: manufacturing date 5
provides information about the age of a tire.
The 1st and 2nd positions represent the cal-
endar week and the 3rd and 4th positions
state the year of manufacture (e.g. "3208"
represents the 32nd week of 2008).
Information on the maximum tire load\bThe data shown in the illustration is example
data.
Maximum tire load 1 is the maximum permissi-
ble weight for which the tire is approved.
Do not overload the tires by exceeding the speci- Ned load limit. The maximum permissible load can
be found on the vehicle\bs tire and loading informa-
tion placard on the B-pillar on the driver\bs side
(  page 377).
SpeciNcations for maximum tire pressure\bThe data shown in the illustration is example
data.
Never exceed maximum tire pressure 1 speci-
Ned for the tire. Always observe the recommen-
ded tire pressure for your vehicle when adjusting
the tire pressure (  page 373).

DeNnition of terms for tires and loading
T ire structure and characteristics: describes the
number of layers or the number of rubber-coated
belts in the tire contact surface and the tire wall.
These are made of steel, nylon, polyester and other materials.
Bar: metric unit for tire pressure. 14.5038 pounds
per square inch (psi) and 100 kilopascal (kPa) is the equivalent of one bar.
DOT (Department of Transportation): DOT-marked
tires fulNll the requirements of the
U.S. Department of Transportation.
Average weight of the vehicle occupants: the
number of vehicle occupants for which the vehicle
is designed, multiplied by 150 lb (68 kg).
Uniform Tire Quality Grading Standards: a uniform
standard to grade the quality of tires with regard
1 "ZR" stated in the tire code.
2 Or "M\fS M" for winter tires.386Wheels and tires

to tread quality, tire traction and temperature
characteristics. The quality grading assessment is
made by the manufacturer following speciNcations
from the U.S. government. The quality grade of a
tire is printed on the side wall of the tire.
Recommended tire pressure: the recommended
tire pressure is the tire pressure speciNed for the
tires mounted on the vehicle at the factory.
The tire and information placard contains the rec-
ommended tire pressure for cold tires, the maxi- mum permissible load and the maximum permissi-
ble vehicle speed.
The tire pressure table contains the recommen-
ded tire pressure for cold tires under various oper-
ating conditions, i.e. loading and/or speed of the vehicle.
Increased vehicle weight due to optional equip- ment: the combined weight of all standard and
optional equipment available for the vehicle, regardless of whether it is actually installed on the
vehicle or not.
Rim: the part of the wheel on which the tire is
installed.GAWR (Gross Axle Weight Rating): the GAWR is
the maximum gross axle weight rating. The actual
load on an axle must never exceed the gross axle
weight rating. The gross axle weight rating can be
found on the vehicle identiNcation plate on the
B!

Maximum load on one tire: maximum load on one
tire. This is calculated by dividing the maximum axle load of one axle by two.
PSI (pounds per square inch): standard unit of
measurement for tire pressure.
Aspect ratio: ratio between tire height and tire
width in percent.
Tire pressure: the pressure inside the tire which
applies an outward force to every square inch of
the tire. The tire pressure is speciNed in pounds
per square inch (psi), in kilopascals (kPa) or in bar. The tire pressure should only be corrected whenthe tires are cold.
Cold tire pressure: the tires are cold when the
vehicle has been parked for at least 3 hours with- out direct sunlight on the tires or the vehicle has
been driven for less than 1 mile (1.6 km).
Tire contact surface: the part of the tire that
comes into contact with the road.
Tire bead: the purpose of the tire bead is to
ensure that the tire sits securely on the wheel rim. There are several wire cores in the tire bead toprevent the tire from changing length on thewheel rim.Side wall: the part of the tire between the tread
and the tire bead.
Weight of optional equipment: the combined
weight of the optional equipment weighing more
than the replaced standard parts and more than 5 lbs (2.3 kg). This optional equipment, such ashigh-performance brakes, level control system, a
roof luggage rack or high-performance batteries,
is not included in the curb weight and the weight of the accessories.
TIN (Tire *dentiNcation Number): a unique identiN-
cation number which can be used by a tire manu-
facturer to identify tires, for example, in a product recall, and thus identify the purchasers. The TIN is
made up of the manufacturer\bs identity code, tire
size, tire type code and the manufacturing date.
Load-bearing index: the load-bearing index is a
code that contains the maximum load-bearing capacity of a tire.
Traction: traction is the grip resulting from friction
between the tires and the road surface.
Wear indicator: narrow bars (tread wear bars) that
are distributed over the tire contact surface. If thetire tread is level with the bars, the wear limit of 1/16 in (1.6 mm) has been reached.
Distribution of vehicle occupants: distribution of
vehicle occupants over designated seat positions
in a vehicle.
Maximum permissible payload weight: nominal
load and luggage load plus 150 lb (68 kg) multi- plied by the number of seats in the vehicle.
