2006 MERCEDES-BENZ E320CDI traction control

352 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.Temperature
The temperature grades are A (the high-
est), B, and C, representing the tire’s resis-
tance 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 tem-
perature can cause the material of the tire
to degenerate and reduce tire life, and ex-
cessive 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 Mo-
tor Vehicle Safety Standard No. 109.
Grades B and A represent higher levels of
performance on the laboratory test wheel
than the minimum required by law.

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.

Possible cause/consequence
Suggested solution
v
The yellow ABS/ESP
® warning
lamp comes on while driving.
The ESP
® is deactivated.
Risk of accident!
Adapt your speed and driving to the prevail-
ing road, weather, and traffic conditions.

Switch the ESP
® back on
(
page 97).
If the ESP
® cannot be switched back on,
have the system checked at an autho-
rized Mercedes-Benz Center as soon as
possible.
The yellow ABS/ESP
® warning
lamp flashes while driving.
The ABS, ESP
® or traction control has come
into operation because of detected traction
loss in at least one tire.
Distronic* is deactivated.

When driving off, apply as little
throttle 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 97).
Failure to follow these instructions in-
creases the risk of an accident.

e-
mand)
The Tele Aid system consists of three
types of response: automatic and man-
ual emergency, roadside assistance
and information. Tele Aid is initially ac-
tivated by completing a subscriber
agreement and placing an acquain-
tance call.
The Tele Aid system is operational pro-
vided that the vehicle’s battery is
charged, properly connected, not dam-
aged and cellular and GPS coverage is
available.
Telematics*
A combination of the terms “telecom-
munications” and “informatics”.

Force times lever arm (e.g. a lug
wrench) with which threaded fasteners
such as wheel bolts are tightened.TIN

Vehicle level control*
The ground clearance of the vehicle is
automatically controlled according to a
selected setting and speed.The driver
can set the ground clearance manually
for example on very rough roads.
Vehicles Maintenance System
(U.S. vehicles)
Maintenance service indicator in the
multifunction display that informs the
driver when the next vehicle mainte-
nance service is due. The Vehicle Main-
tenance System in your vehicle tracks
distance driven and the time elapsed
since your last maintenance service,
calculates other maintenance service
work required, and calls for the next
maintenance service accordingly.
