Vehicle features and options  
This chapter describes all standard, country-  
specific and optional features offered with the  
series. It also describes features that are not  
necessarily available in your vehicle, e. g., due  
to the selected options or country versions.  
This also applies to safety-related functions  
and systems. When using these functions and  
systems, the applicable laws and regulations  
must be observed.  
The tire inflation pressure specifications only  
relate to cold tires or tires at the same temper‐  
ature as the ambient temperature.  
Tires heat up while driving. The tire inflation  
pressure increases with the tire temperature.  
The displays of inflation devices may under-  
read by up to 0.1 bar/2 psi.  
Tires have a natural, consistent loss of tire in‐  
flation pressure.  
Check whether all valve caps are screwed onto  
the tire valves.  
Tire inflation pressure  
Also check the tire inflation pressure of the  
emergency wheel in the cargo area regularly,  
and correct it as needed.  
General information  
The tire characteristics and tire inflation pres‐  
sure influence the following:  
The service life of the tires.  
Road safety.  
After correcting the tire inflation  
pressure

Safety information  
Tire inflation pressure specifications  
WARNING  
The tire inflation pressure table, refer to  
page 221, contains all tire inflation pressure  
specifications for the specified tire sizes at the  
ambient temperature. The tire inflation pres‐  
sure values apply to tire sizes approved by the  
manufacturer of the vehicle for the vehicle  
type.  
A tire with low or missing tire inflation  
pressure impacts handling, such as steering  
and braking response. There is a risk of an ac‐  
cident. Regularly check the tire inflation pres‐  
sure, and correct it as needed, e.g., twice a  
month and before a long trip.◀  
To identify the correct tire inflation pressure,  
please note the following:

All passenger vehicle tires must conform to  
Federal 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. E.g., 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, how‐  
ever, and may depart significantly from the  
norm due to variations in driving habits, service  
practices and differences in road characteris‐  
tics and climate.  
Tire Identification Number  
DOT code: DOT xxxx xxx 2117  
xxxx: manufacturer code for the tire brand  
xxx: tire size and tire design  
2117: tire age  
Tires with DOT codes meet the guidelines of  
the U.S. Department of Transportation.  
Traction  
The traction grades, from highest to lowest,  
are AA, A, B, and C.  
Tire age  
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.  
Recommendation  
Regardless of the tire tread, replace tires at  
least every 6 years.  
Manufacture date  
You can find the manufacture date of the tire  
on the tire's sidewall.  
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  
vehicle tires must meet under the Federal Mo‐  
tor Vehicle Safety Standard No. 109. Grades  
Uniform Tire Quality Grading  
Quality grades can be found where applicable  
on the tire sidewall between tread shoulder  
and maximum section width.

WARNING  
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.◀  
Wear indicators are distributed around the  
tire's circumference and have the legally re‐  
quired minimum height of 0.063 in‐  
ches/1.6 mm.  
RSC – Run-flat tires  
Run-flat tires, refer to page 227, are labeled  
with a circular symbol containing the letters  
RSC marked on the sidewall.  
The positions of the wear indicators are  
marked on the tire sidewall with TWI, Tread  
Wear Indicator.  
M+S  
Winter and all-season tires with better cold  
weather performance than summer tires.  
Tire damage  
Tire tread  
General information  
Inspect your tires regularly for damage, foreign  
objects lodged in the tread, and tread wear.  
Summer tires  
Do not drive with a tire tread of less than  
0.12 in/3 mm, otherwise there is an increased  
risk of hydroplaning.  
Driving over rough or damaged road surfaces,  
as well as debris, curbs and other obstacles  
can cause serious damage to wheels, tires and  
suspension parts. This is more likely to occur  
with low-profile tires, which provide less cush‐  
ioning between the wheel and the road. Be  
careful to avoid road hazards and reduce your  
speed, especially if your vehicle is equipped  
with low-profile tires.  
Winter tires  
Do not drive with a tire tread of less than  
0.16 in/4 mm, as such tires are less suitable for  
winter operation.  
Indications of tire damage or other vehicle mal‐  
functions:  
Unusual vibrations.  
Unusual tire or running noises.  
Unusual handling such as a strong ten‐  
dency to pull to the left or right.  
Damage can be caused by the following situa‐  
tions, for instance:  
Driving over curbs.

Road damage.  
Wheel and tire combination  
General information  
You can ask the dealer’s service center or an‐  
other qualified service center or repair shop  
about the correct wheel/tire combination and  
wheel rim versions for the vehicle.  
Tire inflation pressure too low.  
Vehicle overloading.  
Incorrect tire storage.  
Safety information  
WARNING  
Incorrect wheel/tire combinations impair the  
function of a variety of systems such as ABS or  
DSC.  
Damaged tires can lose tire inflation  
pressure, which can lead to loss of vehicle  
control. There is a risk of an accident. If tire  
damage is suspected while driving, immedi‐  
ately reduce speed and stop. Have wheels and  
tires checked. For this purpose, drive carefully  
to the nearest dealer’s service center or an‐  
other qualified service center or repair shop.  
Have vehicle towed or transported as  
needed.◀  
To maintain good handling and vehicle re‐  
sponse, use only tires with a single tread con‐  
figuration from a single manufacturer.  
Following tire damage, have the original wheel/  
tire combination remounted on the vehicle as  
soon as possible.  
Safety information  
WARNING  
WARNING  
Damaged tires can lose tire inflation  
pressure, which can lead to loss of vehicle  
control. There is a risk of an accident. Do not  
repair damaged tires, but have them re‐  
placed.◀  
Wheels and tires which are not suitable  
for your vehicle can damage parts of the vehi‐  
cle, for instance due to contact with the body  
due to tolerances despite the same official size  
rating. There is a risk of an accident. The man‐  
ufacturer of your vehicle strongly suggests  
that you use wheels and tires that have been  
recommended by the vehicle manufacturer for  
your vehicle type.◀  
WARNING  
Tires can become damaged by driving  
over obstacles, e.g., curbs or road damage, at  
high speed. Larger wheels have a smaller tire  
cross-section. The smaller the tire cross-sec‐  
tion, the higher the risk of tire damage. There  
is a danger of accidents and property damage.  
If possible, drive around obstacles, or drive  
over them slowly and carefully.◀  
Recommended tire brands  
Changing wheels and tires  
Mounting  
Have mounting and wheel balancing carried  
out by a dealer’s service center or another  
qualified service center or repair shop.  
For each tire size, the manufacturer of the ve‐  
hicle recommends certain tire brands. The tire  
brands can be identified by a star on the tire  
sidewall.

Wheels and tires  
Mobility  
New tires  
Rotating wheels between axles  
Tire traction is not optimal due to manufactur‐  
ing circumstances when tires are brand-new;  
they achieve their full traction potential after a  
break-in time.  
Different wear patterns can occur on the front  
and rear axles depending on individual driving  
conditions. The tires can be rotated in pairs  
between the axles to achieve even wear. Fur‐  
ther information is available from a dealer’s  
service center or another qualified service cen‐  
ter or repair shop. After rotating, check the tire  
pressure and correct, if needed.  
Drive conservatively for the first  
200 miles/300 km.  
Retreaded tires  
Rotating the tires between the axes is not per‐  
missible on vehicles with different tire sizes or  
rim sizes on the front and rear axles.  
The manufacturer of your vehicle does not rec‐  
ommend the use of retreaded tires.  
WARNING  
Retreaded tires can have different tire  
casing structures. With advanced age the serv‐  
ice life can be limited. There is a risk of an acci‐  
dent. The manufacturer of your vehicle does  
not recommend the use of retreaded tires.◀  
Storing tires  
Air pressure  
Do not exceed the maximum tire inflation pres‐  
sure indicated on the side wall of the tire.  
Winter tires  
Storage  
Winter tires are recommended for operating on  
winter roads.  
Store wheels and tires in a cool, dry and dark  
place.  
Although so-called all-season M+S tires pro‐  
vide better winter traction than summer tires,  
they usually do not provide the same level of  
performance as winter tires.  
Always protect tires against all contact with oil,  
grease, and solvents.  
Do not leave tires in plastic bags.  
Remove dirt from wheels or tires.  
Maximum speed of winter tires  
If the maximum speed of the vehicle is higher  
than the permissible speed for the winter tires,  
then attach a label showing the permissible  
maximum speed in the field of view. The label  
is available from a dealer’s service center or  
another qualified service center or repair shop.  
Run-flat tires  
Concept  
Run-flat tires permit continued driving under  
restricted conditions even in the event of a  
complete loss of tire inflation pressure.  
With winter tires mounted, observe and do not  
exceed the permissible maximum speed.  
General information  
The wheels consist of tires that are self-sup‐  
porting, to a limited degree, and possibly spe‐  
cial rims.  
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. Further information is availa‐  
ble from a dealer’s service center or another  
qualified service center or repair shop.  
The support of the sidewall allows the tire to  
remain drivable to a restricted degree in the  
event of a tire inflation pressure loss.

such as behind a guardrail.  
If necessary, set up a warning triangle at an  
appropriate distance.  
Safety information  
WARNING  
Your vehicle handles differently with a  
run-flat with no or low inflation pressure; for in‐  
stance, your lane stability when braking is re‐  
duced, braking distances are longer and the  
self-steering properties will change. There is a  
risk of an accident.  
Mobility System  
Concept  
With the Mobility System, minor tire damage  
can be sealed temporarily to enable continued  
travel. To accomplish this, sealant is pumped  
into the tires, which seals the damage from the  
inside.  
Drive moderately and do not exceed a speed of  
50 mph/80 km/h.◀  
Label  
General information  
Follow the instructions on using the Mobi‐  
lity System found on the compressor and  
sealant container.  
Use of the Mobility System may be ineffec‐  
tive if the tire puncture measures approx.  
1/8 inches/4 mm or more.  
Contact a dealer’s service center or an‐  
other qualified service center or repair  
shop if the tire cannot be made drivable.  
The tires are marked on the tire sidewall with  
RSC Run-flat System Component.  
If possible, do not remove foreign bodies  
that have penetrated the tire. Only remove  
foreign objects if they are visibly protruding  
from the tire.  
Repairing a flat tire  
Pull the speed limit sticker off the sealant  
container and apply it to the steering  
wheel.  
Safety measures  
Park the vehicle as far away as possible  
from passing traffic and on solid ground.  
The use of a sealant can damage the TPM  
wheel electronics. In this case, have the  
TPM wheel electronics replaced at the  
next opportunity.  
Switch on the hazard warning system.  
Secure the vehicle against rolling away by  
setting the parking brake.  
The compressor can be used to check the  
tire inflation pressure.  
Turn the steering wheel until the front  
wheels are in the straight-ahead position  
and engage the steering wheel lock.

vehicle only. There is a risk of injury. Do not lift  
any other vehicle or cargo using the vehicle  
jack.◀  
Changing wheels/tires  
General information  
When using run-flat tires or a flat tire kit, a  
wheel does not always need to be changed im‐  
mediately when there is a loss of tire inflation  
pressure due to a flat tire.  
WARNING  
If the vehicle jack is not inserted into the  
jacking point provided for this purpose, the ve‐  
hicle may be damaged or the vehicle jack may  
slip when it is being cranked up. There is a risk  
of injury or risk of damage to property. When  
cranking up the vehicle jack, ensure that it is  
inserted in the jacking point next to the wheel  
housing.◀  
If needed, the tools for changing wheels are  
available as accessories from a dealer’s service  
center or another qualified service center or re‐  
pair shop.  
Safety information  
WARNING  
DANGER  
A vehicle that is raised on a vehicle jack  
may fall off of the jack if lateral forces are ex‐  
erted on it. There is a risk of injury and risk of  
damage to property. While the vehicle is  
raised, do not exert lateral forces on the vehicle  
or pull abruptly on the vehicle. Have a stuck  
wheel removed by a dealer’s service center or  
another qualified service center or repair  
shop.◀  
The vehicle jack is only provided for  
short-term lifting of the vehicle for wheel  
changes. Even if all safety measures are ob‐  
served, there is a risk of the raised vehicle fall‐  
ing, if the vehicle jack tilts over. There is a risk  
of injuries or danger to life. If the vehicle is  
raised, do not lie under the vehicle and do not  
start the engine.◀  
WARNING  
The vehicle jack is provided by the vehi‐  
cle manufacturer for changing wheels in the  
event of a flat tire. The vehicle jack is not de‐  
signed for frequent use, for instance for chang‐  
ing from summer to winter tires. Using the ve‐  
hicle jack frequently may cause it to jam or
