2004 MERCEDES-BENZ S55AMG Torque

291 Operation
Tires and wheels
Rotating wheels
On vehicles with the same wheel size all
around, wheels can be rotated every 3 000
to 6 000 miles (5 000 to 10 000 km), or
sooner if necessary, according to the de-
gree of tire wear. The same direction of tire
rotation must be retained.
Rotate the wheels before the characteris-
tic tire wear pattern becomes visible
(shoulder wear on front wheels and tread
center wear on rear wheels).
Thoroughly clean the inner side of the
wheels after each rotation. Check and en-
sure proper tire inflation pressure. If nec-
essary, activate the tire inflation pressure
monitor.For information on wheel change, see the
“Practical hints” section (
page 344) and
(
page 361).
Warning!
G
Rotate front and rear wheels only if they are
of the same size.
!Your vehicle is equipped with a tire in-
flation pressure monitor, there are
electronic components built into the
wheel.
Do not use mounting tools in the area
of the valve as they could damage the
electronic components.
To prevent damage or incorrect instal-
lation, have the tires changed at an au-
thorized Mercedes-Benz Center.
Warning!
G
Have the tightening torque checked after
changing a wheel. Wheels could become
loose if not tightened with a torque of
110 lb-ft (150 Nm).
Use only genuine Mercedes-Benz wheel
bolts specified for your vehicle's rims.

365 Practical hints
Flat tire
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
110 lb-ft (150 Nm).

Before storing the jack in the trunk, it
should be fully collapsed, with handle
folded in.

Place the wheel bolt wrench, alignment
bolt and jack back in the vehicle tool kit
in the trunk and close the covering lid.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.
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
110 lb-ft. (150 Nm).
!You can also screw the faulty wheel
down into the spare wheel well in the
trunk.
Do not activate the tire inflation pres-
sure monitor* until the depressurized
tire is no longer in the vehicle.

line's ability to resist undesired detona-
tion (knocking). The average of both
the ->MON (Motor Octane Number)
and RON (Research Octane Number) is

TI-KNOCK INDEX.
Shift lock
When the vehicle is parked, this lock
prevents the transmission selector le-
ver from being inadvertently moved out
of positionP without the SmartKey

Seat belts, emergency tensioning de-
vice and airbags. Though independent
systems, they are closely interfaced to

dentification on
D
emand)
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.
