i
When the ESP
® is switched off and one or
more drive wheels are spinning, the ESP
® warn-
ing lampv in the instrument cluster flashes.
However, the ESP
® will then not stabilize the
vehicle.
Warning!
G
When the ESP
® warning lampv is illumi-
nated continuously, the ESP
® is switched
off.
Adapt your speed and driving to the prevail-
ing road conditions and to the non-operating
status of the ESP
®.
!
Avoid spinning of a drive wheel for an
extended period with the ESP
® switched off. This
may cause serious damage to the drivetrain
which is not covered by the Mercedes-Benz
Limited Warranty.
Warning!
G
The ESP
® should not be switched off during
normal driving. Disabling of the system will
result in the following:


no restriction to engine torque


loss of system supported traction
control
“ESP® OFF” is designed for driving on closed
tracks when the natural oversteer and un-
dersteer characteristics are desired and re-
quires a highly skilled and experienced
driver able to handle these critical driving
situations.
You could lose control of your vehicle and
cause an accident.
Please be aware of these limits when you
switch off the ESP
®.
Do not switch off the ESP
® when a spare
wheel is mounted.

589 Operation
Tires and wheels
Rotating tires
Tire rotation can be performed on vehicles
with tires of the same dimension all
around. If your vehicle is equipped with
tires of the same dimension all around,
tires can be rotated, observing a
front-to-rear rotation pattern that will
maintain the intended rotation (spinning)
direction of the tire (
page 564).
In some cases, such as when your vehicle
is equipped with mixed-size tires (different
tire dimension front vs. rear), tire rotation
is not possible.If applicable to your vehicle’s tire configu-
ration, tires can be rotated according to
the tire manufacturer’s recommended in-
tervals in the tire manufacturer’s warranty
pamphlet located in your vehicle literature
portfolio. If none is available, tires should
be rotated every 3 000 to 6 000 miles
(5 000 to 10 000 km), or sooner if neces-
sary, according to the degree of tire wear.
The same rotation (spinning) direction
must be maintained (
page 564).
Rotate tires before the characteristic tire
wear pattern becomes visible (shoulder
wear on front tires and tread center wear
on rear tires).
Thoroughly clean the mounting face of
wheels and brake disks, i.e. the inner side
of the wheels/tires, during each rotation.
Check for and ensure proper tire inflation
pressure.For information on wheel change, see the
“Practical hints” section (
page 696).
Warning!
G
Rotate front and rear wheels only if the tires
are of the same dimension.
If your vehicle is equipped with mixed-size
tires (different tire dimensions front vs.
rear), tire rotation is not possible.
Warning!
G
Have the tightening torque checked after
changing a wheel. Wheels could become
loose if not tightened with a torque of
110 lb-ft (150 Nm).
Only use genuine Mercedes-Benz wheel
bolts specified for your vehicle’s rims.

701 Practical hints
Flat tire
Lowering the vehicle
Lower vehicle by turning crank coun-
terclockwise until vehicle is resting ful-
ly on its own weight.

Remove the jack.
1 - 5 Wheel bolts6 Wheel wrench

Tighten the five wheel bolts evenly,
following the diagonal sequence
illustrated (1 to 5), until all bolts are
tight. Observe a tightening torque of
110 lb-ft (150 Nm).

Fully collapse the jack, with handle
folded in (storage position),
(page 682).

Store the jack and the other vehicle
tools in the designated storage space
underneath the trunk floor.Warning!
G
Have the tightening torque checked after
changing a wheel. The wheels could come
loose if they are not tightened to a torque of
110 lb-ft (150 Nm).i
Do not activate the tire inflation pressure
monitor (
page 572) until a full size wheel/tire
with functioning sensor has been placed back
into service on the vehicle.
