3. Screw in the anti-the wheel bolt with
the a
dapter clockwise at the correct
position and tighten slightly.
On wheels with a wheel cover, the anti-
the wheel bolt must be screwed in at
position → Fig. 226
2 or 3 according to
the position of the tyre valve 1 . Other-
wise, it will not be possible to fit the
wheel c
over.
4. Screw in all the wheel bolts clockwise
and use the box spanner to tighten
them slightly.
5. Lower the vehicle with the jack.
6. Use the box spanner to tighten all the
wheel bolts securely in a clockwise di-
rection →
. Do not tighten the bolts in
clockwise or anticlockwise sequenc
e.
Tighten them in diagonal sequence.
7. Fit the covers or hubcaps → page 369,
→ page 368, → page 370.
Aer changing a wheel
1. Clean the removed wheel and stow it
sec
urely in the spare wheel holder
→ page 366.
2. If necessary, clean the vehicle tools and
stow them safely in the vehicle
→ page 306.
3. Have the tightening torque of the wheel
bolts or wheel nuts checked immedi-
ately → page 352.
4. The damaged wheel should be re-
placed as soon as possible.
Tightening torque for wheel bolts
Specified tightening torque for wheel bolts
for steel or alloy wheels:
— 140 Nm (103 -lbs).
The tightening torque should be checked
with a perfectly functioning torque spanner
immediately aer changing a wheel.
If the wheel bolts are corroded and sti,
they must be renewed and the wheel hub
threads cleaned before the tightening tor-
que is checked.
Never grease or lubricate the wheel bolts or
the threads of the wheel hub. This could
cause them to loosen while the vehicle is in
motion, even if the required tightening tor-
que is used.
WARNING
If the tightening torque of the wheel bolts
is insucient, the wheel bolts and thus
the wheels c
an loosen while the vehicle is
in motion. The wheel bolts and the
threads could be damaged if the tighten-
ing torque is too high.
Incorrectly tightened or missing wheel
bolts can lead to loss of control over the
vehicle, serious accidents and fatal inju-
ries.
·
Always tighten the wheel bolts with the
correct tightening torque. If you do not
have a torque wrench, tighten the
wheel bolts with the wheel bolt wrench
and have the torque checked immedi-
ately by the nearest suitably qualified
workshop.
·
Never drive if wheel bolts are missing or
loose.
·
Always use wheel bolts that match the
wheel rims and the vehicle type.
·
Never grease or oil the wheel bolt and
the threads in the wheel hubs. This
could cause them to loosen while the
vehicle is in motion, even if the required
tightening torque is used.
·
Make sure that the wheel bolts and
threads of the wheel hubs are clean,
smooth-running and free of oil and
grease.
·
Never loosen the bolts on wheel rims
with bolted-on rings.
WARNING
Incorrect wheel bolts can work loose
while driving and lea
d to a loss of vehicle
control, serious accidents and fatal inju-
ries.
·
Always use wheel bolts that match the
wheel rims and the vehicle type.
·
Never use dierent wheel bolts.
