AdjustingVehicle 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.
Sitting safely The ideal seating position can make a vital
contribution to relaxed, fatigue-free driving.
The seating position plays an important role in
an accident in combination with:▷Safety belts, refer to page 51.▷Head restraints, refer to page 52.▷Airbags, refer to page 94.
Seats
General information Do not adjust the seat while driving
Do not adjust the driver's seat while driv‐
ing, or the seat could respond with unexpected
movement and the ensuing loss of vehicle
control could lead to an accident.◀
Do not incline the backrest too far to the
rear
Also on the front passenger side, do not incline
the backrest on the front passenger side too
far to the rear during driving, or there is a risk of
slipping under the safety belt in the event of an
accident. This would eliminate the protection
normally provided by the belt.◀

Adjusting the height▷To raise: pull.▷To lower: press the button, arrow 1, and
push the head restraint down.
Tilt
Three different tilt positions are available.
▷Forward: pull the top edge of the head re‐
straint forward, arrow 1.▷Back: press the button, arrow 2. The head
restraint folds as far back as possible.
Removing
Only remove the head restraint if no one will be
sitting in the seat in question.
1.Pull the head restraint upward as far as
possible.2.Press the button, arrow 1, and pull the
head restraint out completely.
Before transporting passengers
Reinstall the head restraint before trans‐
porting anyone in the seat; otherwise, the pro‐
tective function of the head restraint is unavail‐
able.◀
Seat and mirror memory
General information
Two different driver's seat and exterior mirror
positions can be stored and retrieved for each
remote control. Settings for the backrest width
and lumbar support are not stored in memory.

Adjusting manually 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 park‐
ing, 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 washing the car in an automatic
car wash, fold in the exterior mirrors by hand or
with the button; otherwise, the mirrors could
be damaged, depending 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 dim‐
med. Photocells are used for control in the In‐
terior rear view mirror, refer to page 55.

front, knee and side airbags on the front pas‐
senger side are deactivated.
Deactivate the front passenger airbags auto‐
matically, refer to page 96.
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 re‐
straint fixing system.◀
Seat position and height
Before installing a child restraint fixing system,
move the front passenger seat as far back as
possible and adjust its height to the highest
position to obtain the best possible position for
the belt and to offer optimal protection in the
event of an accident.
Do not change the seat position and height af‐
ter this.
Backrest width Adjustable backrest width: before installing a
child restraint fixing system in the front pas‐
senger seat, open the backrest width com‐
pletely. 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 back‐
rest 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.

LATCH: Lower Anchors and Tether for CHil‐dren.
Note Manufacturer's information for LATCH
child restraint fixing systems
To mount and use the LATCH child restraint
fixing systems, observe the operating and
safety information from the system manufac‐
turer; otherwise, the level of protection may be
reduced.◀

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.◀Seite 185Wheels and tiresMobility185
