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.
WARNING
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 orin combination, can cause heat buildup and
possible tire failure.◀
RSC – Run-flat tires Run-flat tires, refer to page 214, are labeled
with a circular symbol containing the letters
RSC marked on the sidewall.
M+S
Winter and all-season tires with better cold
weather performance than summer tires.
Tire tread Summer tires Do not drive with a tire tread depth of less than
0.12 in/3 mm.
There is an increased danger of hydroplaning if
the tire tread depth is less than 0.12 in/3 mm.
Winter tires
Do not drive with a tire tread depth of less than
0.16 in/4 mm.
Below a tread depth of 0.16 in/4 mm, tires are
less suitable for winter operation.
Minimum tread depth
Wear indicators are distributed around the
tire's circumference and have the legally re‐
quired minimum height of 0.063 in/1.6 mm.
They are marked on the side of the tire with
TWI, Tread Wear Indicator.

WARNING
Too intensive brightness can irritate or
damage the retina of the eye. There is risk of
injuries. Do not look directly into the headlights
or other light sources for an extended period of
time. Do not remove the LED covers.◀
Headlight glass
Condensation can form on the inside of the ex‐
ternal lights in cool or humid weather. When
driving with the lights switched on, the con‐
densation evaporates after a short time. The
headlight glass does not need to be changed.
If despite driving with the lights switched on,
increasing humidity forms, e. g. water droplets
in the lamp, the manufacturer of your vehicle
recommends having it checked by a dealer’s
service center or another qualified service cen‐
ter or repair shop.
Headlight setting
The headlight adjustments can be affected by
changing lights and bulbs. After the headlight
adjustment was changed, have it checked and,
if necessary, corrected by a dealer’s service
center or another qualified service center or re‐
pair shop.
Front lights, bulb replacement
Xenon headlights Information
Because of the long service life of these bulbs,
the likelihood of failure is very low. Switching
the lights on and off frequently shortens their
service life.
If a bulb fails, turn on the front fog lights and
continue the trip with great care. Comply with
local regulations.
DANGER
There can be high voltage in the lighting
system. There is danger to life. The manufac‐
turer of your vehicle recommends that thework on the lighting system including bulb re‐
placement be performed by a dealer’s service
center or another qualified service center or re‐
pair shop.◀
For checking and adjusting headlamp aim,
contact a dealer’s service center or another
qualified service center or repair shop.
