If an electrical malfunction occurs, for example,
press the edges of the mirror glass.
Automatic Curb Monitor
When the reverse gear is engaged, the mirror
glass tilts downward slightly on the front pas‐
senger side. This improves your view of the curb
and other low-lying obstacles when parking, for
example.
Activating1. Slide the mirror changeover switch
to the driver's side mirror position.2.Engage transmission position R.
Deactivating
Slide the mirror changeover switch to the pas‐
senger's side mirror position.
Fold in and out Press the button.
Possible up to approx. 15 mph/20 km/h.
For example, this is advantageous
▷In car washes.▷In narrow streets.▷For folding back mirrors that were folded
away manually.
Mirrors that were folded in are folded out auto‐
matically at a speed of approx. 25 mph/40 km/h.
Fold in the mirror in a car wash
Before entering an automatic car wash,
fold in the exterior mirrors by hand or with the
button; otherwise, they could be damaged, de‐
pending on the width of the vehicle.◀
Automatic heating
Both exterior mirrors are automatically heated
whenever the engine is running.
Automatic dimming feature
Both exterior mirrors are automatically dimmed.
Photocells are used for control in the Interior rear
view mirror, refer to page 56.

Tires with DOT codes meet the guidelines of the
U.S. Department of Transportation.
Tire age

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 202, are labeled with
a circular symbol containing the letters RSC
marked on the sidewall.Seite 199Wheels and tiresMobility199

CareVehicle 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.
Car washes
Hints Steam jets or high-pressure washers
When using steam jets or high-pressure
washers, hold them a sufficient distance away
and use a maximum temperature of
140 ℉/60 ℃.
Ensure that a distance of at least 31.5 in‐
ches/80 cm from the glass sunroof is maintained
at all times. Holding them too close or using ex‐
cessively high pressures or temperatures can
cause damage or preliminary damage that may
then lead to long-term damage.
Follow the user's manual for the high-pressure
washer.◀
Cleaning sensors/cameras with high-
pressure washers
When using high-pressure washers, do not
spray the exterior sensors and cameras, e.g.,
Park Distance Control, for extended periods of
time and only from a distance of at least
12 in/30 cm.◀
Regularly remove foreign items such as leaves
in the area below the windshield when the hood
is raised.
Wash your vehicle frequently, particularly in win‐
ter.Intense soiling and road salt can damage the ve‐
hicle.
Automatic car washes
Notes
Note the following:▷Give preference to cloth car washes or those
that use soft brushes in order to avoid paint
damage.▷Make sure that the wheels and tires are not
damaged by the transport mechanisms.▷Fold in the exterior mirrors; otherwise, they
may be damaged, depending on the width of
the vehicle.▷Deactivate the rain sensor, refer to
page 70,to avoid unintentional wiper activa‐
tion.▷In some cases, an unintentional alarm can be
triggered by the interior motion sensor of the
alarm system. Follow the instructions on
avoiding an unintentional alarm, refer to
page 43.
Guide rails in car washes
Avoid car washes with guide rails higher
than 4 in/10 cm; otherwise, the vehicle body
could be damaged.◀
Before driving into a car wash
In order to ensure that the vehicle can roll in a car
wash, take the following steps:
Manual transmission:
1.Release the parking brake.2.Drive into the car wash.3.Shift to neutral.4.Switch the engine off.5.Switch on the ignition.Seite 226MobilityCare226
