312 OperationTires and wheelsRotating 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 a
front-to-rear rotation pattern that will
maintain the intended rotation (spinning)
direction of the tire (
page 286).
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 286).
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 381).
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.

385 Practical hints
Flat tire
1-5 Wheel bolts
Tighten the five wheel bolts evenly, fol-
lowing the diagonal sequence illustrat-
ed (1 to5), until all bolts are tight.
Observe a tightening torque of
110 lb-ft (150 Nm).
Before storing the jack in the trunk, it
should be fully collapsed, with handle
folded in.
Place the wheel bolt wrench, alignment
bolt and jack back in the vehicle tool kit
in the trunk and close the covering lid.
Replacing jack support tube cover
Slide tongue of cover under the upper
edge of the tube opening.
Applying even pressure, press cover
until it snaps into place. Be careful not
to damage the locking tabs or clamp
the plastic retaining strap.
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).
!You can also screw the faulty wheel
down into the spare wheel well in the
trunk.
Do not activate the tire inflation pres-
sure monitor until the depressurized
tire is no longer in the vehicle.

aged and cellular and GPS coverage is
available.
Telematics
A combination of the terms “telecom-
munications” and “informatics”.
Tightening torque

wrench) with which threaded fasteners
such as wheel bolts are tightened.Tire speed rating
Part of tire designation; indicates the
speed range for which a tire is ap-
proved.
Traction
Force exerted by the vehicle on the
road via the tires.
VIN
(V
