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 58.▷Head restraints, refer to page 59.▷Airbags, refer to page 105.
Front 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.◀

Recommendation
Regardless of wear, replace tires at least every
6 years.
Uniform Tire Quality GradingQuality 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.
TreadwearThe 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 governmenttest 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.◀
RSC – Run-flat tires
Run-flat tires, refer to page 205, are labeled
with a circular symbol containing the letters RSC marked on the sidewall.

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 ℃.
If the vehicle has a glass sunroof, ensure that a distance of at least 31.5 inches/80 cm is main‐
tained. Holding them too close or using exces‐
sively 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
winter.Intense soiling and road salt can damage the
vehicle.
Automatic car washes
Hints
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 80, to avoid unintentional wiper acti‐
vation.▷In some cases, an unintentional alarm can
be triggered by the interior motion sensor
of the alarm system. Follow the instruc‐
tions on avoiding an unintentional alarm,
refer to page 47.
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.Drive into the car wash.2.Engage transmission position N.3.Switch the engine off.
