315 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 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 388) and
(
page 405).
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
96 lb-ft (130 Nm).
Only use genuine Mercedes-Benz wheel
bolts specified for your vehicle’s rims.

i
Check expiration dates and contents for
completeness at least once a year and replace
missing/expired items.
Warning!
G
The jack is designed exclusively for jacking
up the vehicle at the jack tubes built into
both sides of the vehicle. To help avoid per-
sonal injury, use the jack only to lift the ve-
hicle during a wheel change. Never get
beneath the vehicle while it is supported by
the jack. Keep hands and feet away from the
area under the lifted vehicle. Always firmly
set parking brake and block wheels before
raising vehicle with jack.
Do not disengage parking brake while the
vehicle is raised. Be certain that the jack is
always vertical (plumb line) when in use, es-
pecially on hills. Always try to use the jack
on a hard level surface. Be sure that the jack
arm is fully inserted in the jack tube. Always
lower the vehicle onto sufficient capacity
jackstands before working under the vehi-
cle.

390 Practical hintsWhere will I find ...?Storing the spare wheel after use
If you wish to store the spare wheel after
use, carry out the following steps. Other-
wise, the spare wheel may not fit the spare
wheel well.
Unscrew the valve cap from the valve
of the collapsible tire.

Take the valve extractor from the
vehicle tool kit (
page 388).

Unscrew the valve insert from the valve
and allow the air to escape.

Screw the valve insert back into the
valve.

Screw the valve cap back onto the
valve.

Store the spare wheel by carrying out
the steps described in “Removing the
spare wheel” (
page 389) in reverse
order.
Compressing the collapsible tire
(vehicles with 19" spare wheel only)
The collapsible tire on a 19" spare wheel
must be compressed with two tensioning
straps before you can store it back in the
trunk.

Extend the tensioning strap by pulling
the slider.

Place tensioning strap around spare
wheel rim and collapsible tire with the
buckle facing the inside of the rim.

Close the buckle.

Pull the loose end of the tensioning
strap.
The tensioning strap must be pulled as
tight as possible.
!
Make sure the spare wheel is dry before
storing it.
i
It may take a few minutes for the collapsible
tire to deflate completely.
i
Vehicles with 19" spare wheel only: Before
storing the spare wheel in trunk fasten tension-
ing straps, see “Compressing the collapsible tire
(vehicles with 19" spare wheel only)”
(
page 390).
i
The tensioning straps are shown in red for
illustration purposes. The tensioning straps on
the spare wheel of your vehicle are black.

407 Practical hints
Flat tire

Take the vehicle tool kit and the jack
out of the storage compartment under
the trunk floor (
page 388).

On wheel to be changed, loosen but do
not yet remove the wheel bolts (ap-
proximately one full turn with wrench).
The jack support tubes are located behind
the front wheel housings and in front of the
rear wheel housings.
Warning!
G
The jack is designed exclusively for jacking
up the vehicle at the jack tubes built into
both sides of the vehicle. To help avoid per-
sonal injury, use the jack only to lift the ve-
hicle during a wheel change. Never get
beneath the vehicle while it is supported by
the jack. Keep hands and feet away from the
area under the lifted vehicle. Always firmly
set parking brake and block wheels before
raising vehicle with jack.
Do not disengage parking brake while the
vehicle is raised. Be certain that the jack is
always vertical (plumb line) when in use, es-
pecially on hills. Always try to use the jack
on level surface. Be sure that the jack arm is
fully inserted in the jack tube. Always lower
the vehicle onto sufficient capacity jack-
stands before working under the vehicle.
Warning!
G
When turning the wheel wrench to loosen
the wheel bolts, make sure you position
hands on the wrench in such a way that you
avoid injury to yourself, such as scraping
your hands against the wheel. Make sure
turning the wheel wrench will not scratch or
damage the wheel rim.
