Tires and wheels
See an authorized Mercedes-Benz Center
for information on tested and
recommended rims and tires for summer
and winter operation. They can also offer
advice concerning tire service and
purchase.
Important guidelines
Only use sets of tires and rims of the
same type and make.
Tires must be of the correct size for the
rim.
Break in new tires for approximately
60 miles (100 km) at moderate
speeds.
Regularly check the tires and rims for
damage. Dented or bent rims can
cause tire inflation pressure loss and
damage to the tire beads.
If vehicle is heavily loaded, check tire
inflation pressure and correct as
required.
Do not allow your tires to wear down
too far. Adhesion properties on wet
roads are sharply reduced at tread
depths under
1/8in (3 mm).
When replacing individual tires, you
should mount new tires on the front
wheels first (on vehicles with
same-sized wheels all around).
Warning!
G
Replace rims or tires with the same designa-
tion, manufacturer and type as shown on the
original part. See an authorized
Mercedes-Benz Center for further informa-
tion. If incorrectly sized rims and tires are
mounted:
The wheel brakes or suspension
components can be damaged.
The operating clearance of the wheels
and the tires may no longer be correct.
Warning!
G
Worn, old tires can cause accidents. If the
tire tread is badly worn, or if the tires have
sustained damage, replace them.
When replacing rims, only use genuine
Mercedes-Benz wheel bolts specified for the
particular rim type. Failure to do so can
result in the bolts loosening and possibly an
accident.
Retreaded tires are not tested or recom-
mended by Mercedes-Benz, since previous
damage cannot always be recognized on re-
treads. The operating safety of the vehicle
cannot be assured when such tires are used.

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.

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.

409 Practical hints
Flat tire
Keeping jack in this position, turn
crank3 clockwise until the jack base
meets the ground. Make sure the jack
is vertical (plumb line).
Continue to turn the crank until the tire
is a maximum of 1.2 in (3 cm) from the
ground.Removing the wheel
1Alignment bolt
Unscrew upper-most wheel bolt and re-
move.
Replace this wheel bolt with alignment
bolt1 supplied in the tool kit.
Remove the remaining bolts.
Remove the wheel.Mounting the new wheel
Clean contact surfaces of wheel and
wheel hub.
Guide the spare wheel onto the align-
ment bolt and push it on.
Insert wheel bolts and tighten them
slightly.
!
Do not place wheel bolts in sand or dirt. This
could result in damage to the bolt and wheel hub
threads.
Warning!
G
Inflate spare wheel tire only after the wheel
is properly mounted.
Inflate the spare wheel tire using the electric
pump (
page 410) before
lowering the ve-
hicle.

410 Practical hintsFlat tire
Unscrew the alignment bolt, install last
wheel bolt and tighten slightly.
Inflating the spare tire (collapsible tire)
Take the electric air pump out of the
trunk (
page 388).1Flap

3Electrical plug
4Air hose with pressure gauge and vent
screw
5Union nut
Open flap 1 on air pump.
Pull out electrical plug 3 and air hose
with the pressure gauge 4.
Remove the valve cap from the tire
valve.
Screw union nut 5 onto the tire valve.
Insert electrical plug 3 into vehicle ci-
gar lighter socket.
Warning!
G
Always replace wheel bolts that are dam-
aged or rusted.
Never apply oil or grease to wheel bolts.
Damaged wheel hub threads should be re-
paired immediately. Do not continue to drive
under these circumstances! Contact an au-
thorized Mercedes-Benz Center or call
Roadside Assistance.
Incorrect wheel bolts or improperly tight-
ened wheel bolts can cause the wheel to
come off. This could cause an accident. Be
sure to use the correct wheel bolts.
Warning!
G
Only use genuine equipment
Mercedes-Benz wheel bolts. They are identi-
fied by the Mercedes star. Other wheel bolts
may come loose.
Do not tighten the wheel bolts when the ve-
hicle is raised. Otherwise the vehicle could
fall off the jack.!
Do not lower the vehicle before inflating the
spare wheel tire. Otherwise the rim may be dam-
aged.
Warning!
G
Observe instructions on air pump label.

412 Practical hintsFlat tireLowering the vehicle
Lower vehicle by turning crank coun-
terclockwise until the full weight of the
vehicle is resting on the ground.
Pull the jack out of the jack support
tube.
1 - 5 Wheel bolts
Tighten the five wheel bolts evenly, fol-
lowing the diagonal sequence illustrat-
ed (1 to 5), until all bolts are tight.
Observe a tightening torque of 96 lb-ft
(130 Nm).
Before storing the jack in the trunk,
crank back to storage position and fold
in the arm.
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.
i
The flat tire may be transported in the trunk
when the retractable hardtop is raised. If avail-
able, use a protective sheet on the spare wheel.
Vehicles with TPMS or Advanced TPMS*:
Do not activate the tire inflation pressure moni-
tor until a full size wheel/tire with functioning
sensor has been placed back into service on the
vehicle.
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
96 lb-ft (130 Nm).Warning!
G
When turning the wheel wrench to tighten
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.
