336 OperationTires and wheelsIf 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 310). 
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 402) and 
(
page 419).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.

422 Practical hintsFlat tire
Unscrew the alignment bolt, install last 
wheel bolt and tighten slightly.In the case of a flat tire, you may tempo-
rarily use the Minispare wheel when ob-
serving 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 re-
placed as appropriate.
Do not operate vehicle with more than 
one spare wheel mounted.Lowering the vehicle
Lower vehicle by turning crank coun-
terclockwise until vehicle is resting ful-
ly on its own weight.
Remove the jack.
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).
Warning!
G
Use only 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 
tip over.
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 spare wheel should only be used tempo-
rarily, and replaced with a regular road 
wheel as quickly as possible.

vided that the vehicle’s battery is 
charged, properly connected, not dam-
aged and cellular and GPS coverage is 
available.
