350 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 a
front-to-rear rotation pattern that will
maintain the intended rotation (spinning)
direction of the tire (
page 326).
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 326).
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 404) and
(
page 436).
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
80 lb-ft (110 Nm).
Only use Genuine Mercedes-Benz wheel
bolts specified for your vehicle’s rims.

Make sure arrow 2 on vehicle tool kit
storage well casing4 points in the
direction of travel.
Place storage well casing (page 405)
over the vehicle tool kit storage well
casing 4 and turn the retaining screw
(
page 405) clockwise as far it will go
to secure the Minispare wheel.
Disengage trunk floor handle in upper
edge of trunk and lower trunk floor cov-
er.
iArrow2 on vehicle tool kit storage well
casing4 must point in the direction of travel.
Otherwise you cannot place the storage well cas-
ing (
page 405) on top and secure the Minis-
pare wheel with the retaining screw
(
page 405).
!To prevent damage, always disengage trunk
floor handle from upper edge of trunk and lower
trunk floor before closing the trunk.
Warning!G
The dimensions of the Minispare wheel are
different from those of the road wheels. As
a result, the vehicle handling characteristics
change when driving with a Minispare wheel
mounted.
The Minispare wheel should only be used
temporarily, and should be replaced with a
regular road wheel as quickly as possible.
Do not switch off the ESP
® when a Minis-
pare wheel is mounted.
441 Practical hints
Flat tire
Mounting the Minispare wheel Preparing the vehicle
Prepare the vehicle as described on
(
page 436).
Take the wheel wrench, alignment bolt,
collapsible wheel chock, and the jack
out of the trunk (
page 407).
Take the Minispare wheel and wheel
bolts out of the trunk (
page 407).Lifting the vehicle
Prevent the vehicle from rolling away
by blocking wheels with wheel chocks
or other sizeable objects.
One wheel chock is included with the
vehicle tool kit (
page 404).
When changing wheel on a level surface:
Place the wheel chock in front of and
another sizeable object behind the
wheel that is diagonally opposite to the
wheel being changed.
Always try lifting the vehicle using the jack
on a level surface. However, should cir-
cumstances require you to do so on a hill,
place the wheel chock and the other size-
able object as follows:
Place the wheel chock and another
sizeable object on the downhill side
blocking both wheels of the axle not
being worked on.
Warning!G
The dimensions of the Minispare wheel are
different from those of the road wheels. As
a result, the vehicle handling characteristics
change when driving with a Minispare wheel
mounted. Adapt your driving style
accordingly.
The spare wheel is for temporary use only.
When driving with spare wheel mounted,
ensure proper tire inflation pressure and do
not exceed a vehicle speed of 50 mph
(80 km/h).
Drive to the nearest Mercedes-Benz Center
as soon as possible to have the spare wheel
replaced with a regular road wheel.
Never operate the vehicle with more than
one Minispare wheel mounted.
Do not switch off the ESP
® when a Minis-
pare wheel is mounted.
