Run-flat tires
Maximum speed
You can continue driving with a damaged tire
at speeds up to 50 mph/80 km/h.
Continued driving with a flat tire
If continuing to drive with a damaged tire:
1.Avoid sudden braking and steering maneu‐
vers.2.Do not exceed a speed of 50 mph/80 km/h.3.Check the air pressure in all four tires at
the next opportunity.
If the tire inflation pressure in all four tires
is correct, it is possible that a reset was not
carried out for the Tire Pressure Monitor. In
that case, carry out a reset.
Possible driving distance with complete loss of
tire inflation pressure:
The possible driving distance after a loss of tire
inflation pressure depends on the cargo load
and the driving style and conditions.
For a vehicle containing an average load, the
possible driving distance is approx.
50 miles/80 km.
When the vehicle is driven with a damaged tire,
its handling characteristics change, e.g., re‐
duced lane stability during braking, a longer
braking distance, and altered self-steering
properties. Adjust your driving style accord‐
ingly. Avoid abrupt steering maneuvers or driv‐
ing over obstacles, e.g., curbs, potholes, etc.
Because the possible driving distance de‐
pends on how the vehicle is used during the
trip, the actual distance may be smaller or
greater depending on the driving speed, road
conditions, external temperature, cargo load,
etc.
Continued driving with a flat tire
Drive moderately and do not exceed a
speed of 50 mph/80 km/h.
A loss of tire inflation pressure results in a
change in the handling characteristics, e.g., re‐
duced lane stability during braking, a longer
braking distance and altered self-steering
properties.◀
Final tire failure
Vibrations or loud noises while driving
can indicate the final failure of the tire. Reduce
speed and stop; otherwise, pieces of the tire
could come loose and cause an accident. Do
not continue driving, and contact your service
center.◀
Required inflation pressure check
message
A Check Control message is displayed.
Check the tire inflation pressure and carry out
a reset of the system.
In some cases, a wheel was changed without
having carried out a reset.
System limits
The system does not function properly if a re‐
set has not been carried out, e.g., a flat tire is
reported even though the tire inflation pres‐
sures are correct.
The tire pressure depends on the temperature
of the tire. If the tire temperature rises, e.g.,
due to driving or because of the heat of the
Sun, the tire inflation pressure increases also.
The tire pressure is reduced when the tire
temperature falls again. This behavior may
cause a warning to be issued if temperatures
fall very sharply.
Malfunction The yellow warning lamp flashes and
then lights up continuously. A CheckSeite 107SafetyControls107

LoadingVehicle equipment
All standard, country-specific and optional
equipment that is offered in the model series is
described in this chapter. Therefore, equip‐
ment is also described that is not available in a
vehicle, e. g., because of the selected optional
equipment or country variant. This also applies
for safety-related functions and systems.
Hints Overloading the vehicle
To avoid exceeding the approved carry‐
ing capacity of the tires, never overload the ve‐
hicle. Overloading can lead to overheating and
increases the rate at which damage develops
inside the tires. This could result in a sudden
loss of tire inflation pressure.◀
No fluids in the trunk
Make sure that fluids do not leak into the
trunk; otherwise, the vehicle may be dam‐
aged.◀
Determining the load limit1.Locate the following statement on your ve‐
hicle’s placard:▷The combined weight of occupants
and cargo should never exceed XXX kg
or YYY lbs. Otherwise, damage to thevehicle and unstable driving situations
may result.2.Determine the combined weight of the
driver and passengers that will be riding in
your vehicle.3.Subtract the combined weight of the driver
and passengers from XXX kilograms or
YYY pounds.4.The resulting figure equals the available
amount of cargo and luggage load ca‐
pacity.
For example, if the YYY amount equals
1,000 lbs and there will be four 150 lbs
passengers in your vehicle, the amount of
available cargo and luggage load capacity
is 400 lbs: 1,000 lbs minus 600 lbs =
400 lbs.5.Determine the combined weight of lug‐
gage and cargo being loaded on the vehi‐
cle. That weight may not safely exceed the
available cargo and luggage load capacity
calculated in Step 4.
Load
The maximum load is the sum of the weight of
the occupants and the cargo.
The greater the weight of the occupants, the
less cargo that can be transported.

xxxx: manufacturer code for the tire brand
xxx: tire size and tire design
1013: tire age
Tires with DOT codes meet the guidelines of
the U.S. Department of Transportation.
Tire age DOT … 1013: the tire was manufactured in the
10th week 2013.
Recommendation
Regardless of wear, replace tires at least every
6 years.
Uniform Tire Quality Grading
Quality grades can be found where applicable
on the tire sidewall between tread shoulder
and maximum section width.
For example: Treadwear 200; Traction AA;
Temperature A
DOT Quality Grades Treadwear
Traction AA A B C
Temperature A B C
All passenger car tires must conform to Fed‐
eral Safety Requirements in addition to these
grades.
Treadwear The treadwear grade is a comparative rating
based on the wear rate of the tire when tested
under controlled conditions on a specified gov‐
ernment test course. For example, a tire graded 150 would wear one and one-half, 1 g,times as 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 signifi‐
cantly from the norm due to variations in driv‐
ing habits, service practices and differences in
road characteristics and climate.Traction
The traction grades, from highest to lowest,
are AA, A, B, and C.
Those grades represent the tire's ability to
stop on wet pavement as measured under
controlled conditions on specified government
test surfaces of asphalt and concrete. A tire
marked C may have poor traction performance.
The traction grade assigned to this tire is
based on straight-ahead braking traction tests,
and does not include acceleration, cornering,
hydroplaning, or peak traction characteristics.
Temperature
The temperature grades are A, the highest, B,
and C, representing the tire's resistance to the
generation of heat and its ability to dissipate
heat when tested under controlled conditions
on a specified indoor laboratory test wheel.
Sustained high temperature can cause the ma‐
terial of the tire to degenerate and reduce tire
life, and excessive temperature can lead to
sudden tire failure. The grade C corresponds
to a level of performance which all passenger
car tires must meet under the Federal Motor
Vehicle Safety Standard No. 109. Grades Band
A represent higher levels of performance on
the laboratory test wheel than the minimum re‐
quired by law.
Temperature grade for this tire
The temperature grade for this tire is es‐
tablished for a tire that is properly inflated and
not overloaded. Excessive speed, underinfla‐
tion, or excessive loading, either separately or
in combination, can cause heat buildup and
possible tire failure.
If necessary, have the vehicle towed.◀
RSC – Run-flat tires
Run-flat tires, refer to page 208, are labeled
with a circular symbol containing the letters
RSC marked on the sidewall.Seite 205Wheels and tiresMobility205

the winter tires; otherwise, tire damage and ac‐
cidents can occur.◀
Run-flat tires If you are already using run-flat tires, for your
own safety you should replace them only with
the same kind. No spare tire is available in the
case of a flat tire. Your service center will be
glad to advise you.
Rotating wheels between axles The manufacturer of your vehicle advises
against switching wheels between the front
and rear axles.
This can impair the handling characteristics.
StorageStore wheels and tires in a cool, dry place with
as little exposure to light as possible.
Always protect tires against all contact with oil,
grease and fuels.
Do not exceed the maximum tire inflation pres‐
sure indicated on the side wall of the tire.Run-flat tires
Label

The wheels are composed of special rims and
tires that are self-supporting, to a limited de‐
gree.
The support of the sidewall allows the tire to
remain drivable to a restricted degree in the
event of a pressure loss.
