2007 MERCEDES-BENZ SL55AMG traction control

310 OperationTires and wheelsQuality grades can be found, where appli-
cable, on the tire sidewall between tread
shoulder and maximum section width. For
example:
All passenger car tires must conform to
federal safety requirements in addition to
these grades.Treadwear
The treadwear grade is a comparative rat-
ing based on the wear rate of the tire when
tested under controlled conditions on a
specified government test course. For ex-
ample, a tire graded 150 would wear one
and one-half (1
1/2) 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 climate.Traction
The traction grades, from highest to low-
est, are AA, A, B, and C. Those grades rep-
resent 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 perfor-
mance.

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.

318 OperationWinter drivingSnow chainsSnow chains should only be driven on
snow-covered roads at speeds not to ex-
ceed 30 mph (50 km/h). Remove chains
as soon as possible when driving on roads
without snow.
Please observe the following guidelines
when using snow chains:


Use of snow chains is not permissible
with all wheel/tire combinations
(page 435).


Use snow chains in pairs and on rear
wheels only. Follow the manufacturer’s
mounting instructions.


Only use snow chains that are ap-
proved by Mercedes-Benz. Any autho-
rized Mercedes-Benz Center will be
glad to advise you on this subject.


Use of snow chains may be prohibited
depending on location. Always check
local and state laws before installing
snow chains.


Do not use snow chains on the spare
wheel (
page 440).


Do not use snow chains on wheels with
MOExtended tires* (
page 439).
!
When driving with snow chains, always se-
lect setting 1 of the level control system
(
page 225). Other settings may result in dam-
age to your vehicle.
!
Some tire sizes do not leave adequate clear-
ance for snow chains. To help avoid serious dam-
age to your vehicle or tires, use of snow chains is
not permissible with


285/35 R18 97W


285/35 R18 97Y


285/35 ZR18 97Y


285/30 ZR19 98Y XL (Extra Load)
!
If snow chains are mounted to the front
wheels, they may scrape against the body or axle
components. The tires or the vehicle could be
damaged as a result.
i
When driving with snow chains, you may
wish to deactivate the ESP
® (page 91) before
setting the vehicle in motion. This will improve
the vehicle’s traction.

Suggested solution
v
The yellow ABS/ESP
® warning
lamp flashes while driving.
The ESP
®, ABS, or traction control has come
into operation because of detected traction
loss in at least one tire.
The cruise control and the Distronic* system
are deactivated.

When driving off, apply as little throt-
tle as possible.

While driving, ease up on the acceler-
ator.

Adapt your speed and driving to the
prevailing road and weather condi-
tions.

Do not deactivate the ESP
®.
Exceptions: (
page 91).
Failure to follow these instructions in-
creases the risk of an accident.
