335 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 308).
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 308).
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 380) and
(
page 404).
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.

384 Practical hints
Where will I find ...?
Pierce the protective wrap with
retaining screw3.
Secure the spare wheel by turning re-
taining screw3 clockwise.In case of a flat tire, you may temporarily
use the spare wheel with collapsible tire
when observing the following restrictions:
Do not exceed a vehicle speed of
50 mph (80 km/h).
Drive to the nearest tire repair facility
to have the flat tire repaired or
replaced as appropriate.
Do not operate vehicle with more than
one spare wheel mounted.
For more information, see “Rims and Tires”
(
page 429).
!
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 spare wheel with
collapsible tire are different from those of
the road wheels. As a result, the vehicle han-
dling characteristics change when driving
with a spare wheel mounted.
The spare wheel with collapsible tire should
only be used temporarily, and should be re-
placed with a regular road wheel as quickly
as possible.

404 Practical hints
Flat tire
Preparing the vehicle
Park the vehicle in a safe distance from
moving traffic on a hard, flat surface
when possible.
Turn on the hazard warning flasher
(
page 119).
Turn the steering wheel so that the
front wheels are in a straight ahead
position.
Set the parking brake (page 54).
Move the gear selector lever toP.
Turn off the engine (page 56).
Remove the SmartKey from the starter
switch.
Have any passenger exit the vehicle at
a safe distance from the roadway.
Mounting the spare wheel
Preparing the vehicle
Prepare the vehicle as described
(
page 404).
Take the collapsible tire, wheel wrench,
wheel bolts, jack, and electric air pump
out of the trunk (
page 380).
Warning!G
The dimensions of the spare wheel with col-
lapsible tire are different from those of the
road wheels. As a result, the vehicle han-
dling characteristics change when driving
with a spare wheel mounted. Adapt your
driving style accordingly.
The spare wheel is for temporary use only.
When driving with spare wheel mounted,
ensure proper tire pressure and do not ex-
ceed 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 spare wheel mounted.
Do not switch off the ESP
® when a spare
wheel is mounted.
i
Open doors only when conditions are
safe to do so.
