2007 MERCEDES-BENZ ML320CDI traction control

393 Operation
Tires and wheels
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
Motor 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.
Warning!
G
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.

420 Practical hintsWhat to do if …Problem
Possible cause/consequence
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 99).
Failure to follow these instructions
increases the risk of an accident.
The yellow fuel tank reserve
warning lamp in the fuel gauge
comes on while driving.
The fuel level has gone below the reserve
mark.

Refuel at the next gas station
(page 352).

See Operator’s Manual
If the yellow ESP
® warning
lampv flashes while driving and
this message appears, the electron-
ic traction system has switched off
to prevent overheating of the drive
wheel brakes.
As soon as the brakes have cooled off,
the electronic traction system switches
on again.
The message in the multifunction dis-
play disappears and the ESP
® warning
lampv goes out.
The self-diagnosis has not yet been
completed yet.
The display will clear after driving a
short distance at a vehicle speed of
above 12 mph (20 km/h).
Cruise control and
SPEEDTRONIC
inoperative
The cruise control is malfunctioning.

Have cruise control checked by an
authorized Mercedes-Benz Light
Truck Center.
Cruise control
--- mph
You have attempted to set a speed
while driving below 20 mph
(30 km/h).

Accelerate to a speed exceeding
20 mph (30 km/h) and set the
speed (
page 245).
The ESP
® is switched off.

Switch on the ESP
® (page 98).
The automatic transmission is set to
positionP, R, orN.

Set the automatic transmission to
positionD (
page 187).
The vehicle is secured with the
parking brake.

Release the parking brake
(page 57).
