E Put the jack aside.
1 — 5 Wheel bolts
E Tighten all wheel bolts evenly in the se-
quence indicated.
! The tightening torque is:
I
180 Nm ± 10 Nm for steel wheels
I
150 Nm ± 10 Nm for light alloy wheels
E Wheels with wheel trim: fit the wheel
trim with the opening for the valve over
and press onto the wheel in this posi-
tion.
E Carefully push the wheel trim against
the wheel opposite the valve until it en-
gages. Make sure the retaining catches
on the trim engage in the wheel.
E Turn the jack back to its out-of-use po-
sition.
E Stow away the jack and the rest of the
vehicle tool kit.
E Secure the faulty wheel in the spare
wheel bracket (
e page 266).
E Check the tyre pressure and correct if
necessary (
e page 352).
E After 50 km retighten the wheel bolts
to the specified torque.
Tightening the wheel bolts

Risk of accident
After changing a wheel, you must, for safety
reasons:
I
have the tightening torque checked. The
wheels could otherwise work loose
I
check the tyre pressure and correct if
necessary
I
retighten the wheel bolts to the speci-
fied tightening torque after driving
50 km
I
if new or repainted wheels are fitted, the
wheel bolts must be retightened again
after approximately 1,000 to 5,000 km
to the specified tightening torque.
I
have the direction of tyre rotation cor-
rected, if reversed, as soon as possible
at a qualified specialist workshop, e.g. a
Mercedes-Benz Service Centre. The ve-
hicle handling characteristics could oth-
erwise be affected.
Otherwise, the operating reliability and road
safety of the vehicle could be jeopardised.
This could cause you to lose control of the
vehicle, resulting in an accident and injuring
yourself or others.
