On the front passenger seat
Deactivating airbags
After installing a child restraint fixing system in
the front passenger seat, make sure that the
front, knee and side airbags on the front pas‐
senger side are deactivated.
Deactivate the front passenger airbags auto‐
matically, refer to page 104
Deactivating the front passenger airbags
If a child restraint fixing system is used in
the front passenger seat, the front passenger
airbags must be deactivated; otherwise, there is
an increased risk of injury to the child when the
airbags are triggered, even with a child restraint
fixing system.◀
Seat position and height
Before installing a child restraint fixing system,
move the front passenger seat as far back as
possible and bring it up to medium height to ob‐
tain the best possible position for the belt and to
offer optimal protection in the event of an acci‐
dent.
Do not change the seat position and height after
this.
Backrest width
Adjustable backrest width: before installing a
child restraint fixing system in the front passen‐
ger seat, open the backrest width completely.
Do not change the backrest width again and do
not call up a memory position.
Backrest width for the child seat
Before installing a child restraint fixing
system in the front passenger seat, the backrest
width must be opened completely. Do not
change the adjustment after this; otherwise, the
stability of the child seat will be reduced.◀Child seat security
The rear safety belts and the front passenger
safety belt can be locked against pulling out for
mounting the child restraint fixing systems.
Locking the safety belt
1.Pull out the belt webbing completely.2.Secure the child restraint fixing system with
the belt.3.Allow the belt webbing to be pulled in and
pull it taut against the child restraint fixing
system. The safety belt is locked.
Unlocking the safety belt
1.Unbuckle the belt buckle.2.Remove the child restraint fixing system.3.Allow the belt webbing to be pulled in com‐
pletely.

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‐Seite 195Wheels and tiresMobility195

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 77,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 44.
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:
1.Release parking brake, refer to page 72, and
deactivate Automatic Hold, refer to
