357 Operation
Tires and wheels
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 331).
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, activating the Tire Pressure 
Monitoring System* (TPMS*) 
(
page 339) if necessary.For information on wheel change, see the 
“Practical hints” section (
page 422) and 
(
page 441).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.

447 Practical hints
Flat tire
Store the electrical plug 3 and the air 
hose 4 behind the flap 1 and place 
the electric air pump back in the desig-
nated storage space underneath the 
trunk floor (
page 422).
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).
Before storing the jack, it should be fully 
collapsed, with handle folded in (storage 
position).
Store the jack and the other vehicle 
tools in the designated storage space 
underneath the trunk floor 
(page 422).
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).
iWrap the damaged wheel in the protec-
tive film that comes with the spare 
wheel and put the wheel in the trunk.
You can also place the damaged wheel 
down into the spare wheel well. In this 
case, you must stow the holder from 
the spare wheel well in the trunk.
Do not activate the tire pressure moni-
toring system* until the depressurized 
tire is no longer in the vehicle.

The Tele Aid system consists of three 
types of response: automatic and man-
ual emergency, roadside assistance 
and information. Tele Aid is initially ac-
tivated by completing a subscriber 
agreement and placing an acquain-
tance call.
The Tele Aid system is operational pro-
vided that the vehicle’s battery is 
charged, properly connected, not dam-
aged and cellular and GPS coverage is 
available.
Telematics*
A combination of the terms “telecom-
munications” and “informatics”.
Tightening torque
Force times lever arm (e.g. a lug 
wrench) with which threaded fasteners 
such as wheel bolts are tightened.TIN

Vehicle level control*
The ground clearance of the vehicle is 
automatically controlled according to a 
selected setting and speed.The driver 
can set the ground clearance manually 
for example on very rough roads.
Vehicles Maintenance System 
(U.S. vehicles)
Maintenance service indicator in the 
multifunction display that informs the 
driver when the next vehicle mainte-
nance service is due. The Vehicle Main-
tenance System in your vehicle tracks 
distance driven and the time elapsed 
since your last maintenance service, 
calculates other maintenance service 
work required, and calls for the next 
maintenance service accordingly.
