Activating the voice activation system
1. Briefly press the button on the
steering wheel.2.Say the command.
Terminating the voice activation
system
Briefly press the button on the steering
wheel or ›Cancel‹.
Possible commands
Having possible commands read aloud
Press the button. ›Help‹. Possible commands
are announced.
The digits from zero to nine are recognized. The
digits can be spoken separately or combined in
a sequence to accelerate the entry.
Using alternative commands
The system often recognizes a number of dif‐
ferent commands to run a function; for instance:
›Dial name‹ or ›Name‹
Example: dialing a phone number
1. Briefly press the button on the
steering wheel.2.›Dial number‹
The system says: »Please say the number«3.E.g., ›123 456 790‹The system says: »123 456 790. Continue?

Wheels and tiresVehicle equipment
All standard, country-specific and optional
equipment that is offered in the model series is
described in this chapter. Therefore, equipment
is also described that is not available in a vehicle,
e. g., because of the selected optional equip‐
ment or country variant. This also applies for
safety-related functions and systems.
Tire inflation pressure
Safety information
The tire characteristics and tire inflation pres‐
sure influence the following:▷The service life of the tires.▷Road safety.▷Driving comfort.
Checking the pressure
Only check the tire inflation pressure when the
tires are cold. This means after driving no more
than 1.25 miles/2 km or when the vehicle has
been parked for at least 2 hours. When the tires
are warm, the tire inflation pressure is higher.
Check the tire inflation pressure regularly
Regularly check the tire inflation pressure
and correct it as needed: at least twice a month
and before a long trip. If you fail to observe this
precaution, you may be driving on tires with in‐
correct tire pressures, a condition that may not
only compromise your vehicle's driving stability,
but also lead to tire damage and the risk of an
accident.◀
After correcting the tire inflation pressure:
▷Reinitialize the Flat Tire Monitor.▷Reinitialize the Tire Pressure Monitor.Pressure specifications
The tire inflation pressure table, refer to
page 246, contains all pressure specifications
for the specified tire sizes at the ambient tem‐
perature. Pressure specifications apply to ap‐
proved tire sizes and recommended tire brands.
This information can be obtained from your
service center.
To identify the correct tire inflation pressure,
please note the following:▷Tire sizes of your vehicle.▷Maximum allowable driving speed.
Tire inflation pressures up to 100 mph/
160 km/h
For speeds of up to 100 mph/160 km/h and for
optimum driving comfort, note the pressure val‐
ues in the tire inflation pressure table, refer to
page 246, and adjust as necessary.
These pressure values can also be found on the
tire inflation pressure label on the driver's door
pillar.
Maximum permissible speed
Do not exceed 100 mph/160 km/h; other‐
wise, tire damage and accidents may result.◀

Tires with DOT codes meet the guidelines of the
U.S. Department of Transportation.
Tire age
DOT … 3510: the tire was manufactured in the
35th week in 2010.
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 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. 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 significantly from the norm due
to variations in driving habits, service practices
and differences in road characteristics and cli‐
mate.
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 surfa‐
ces 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, hydro‐
planing, 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. Sus‐
tained high temperature can cause the material
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 required 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 pos‐
sible tire failure.
If necessary, have the vehicle towed.◀
RSC – Run-flat tires
Run-flat tires, refer to page 253, are labeled with
a circular symbol containing the letters RSC
marked on the sidewall.

weather performance than summer tires.Seite 250MobilityWheels and tires250
