Loosening wheel bolts
● Fit the wheel brace as far as it will go over the wheel bolt ⇒ Fig. 144.
● Hold the wheel brace at the end and rotate the bolt approximately one
turn anticlockwise ⇒ 
.
Loosening anti-theft wheel bolts
For wheels with full hubcap, the anti-theft wheel lock must be threaded into
position ⇒ Fig. 145 2
before mounting the hubcap. Otherwise it will not be
possible to mount the full hubcap.
● Take the adapter for anti-theft wheel bolts out of the vehicle tool kit.
● Insert the adapter onto the wheel bolt ⇒ Fig. 145. Push it on as far as it
will go.
● Fit the wheel brace onto the adapter as far as possible.
● Hold the wheel brace at the end and rotate the bolt approximately one
turn anticlockwise ⇒ 
.
Important information about wheel bolts
The wheel rims and bolts have been designed to be fitted to factory op-
tions. If different rims are fitted, the correct wheel bolts with the right length
and correctly shaped bolt heads must be used. This ensures that wheels are
fitted securely and that the brake system functions correctly.
In some circumstances, wheel bolts from the same model vehicle should
not be used.
Wheel bolt tightening torque
The prescribed tightening torque for wheel bolts for steel and alloy wheels
is 110 Nm. Have the tightening torque of the wheel bolts checked as soon
as possible with a reliable torque wrench. If wheel bolts are rusty and it is difficult to tighten them, the threads should
be replaced and cleaned before checking the tightening torque.
Never grease or lubricate wheel bolts or the wheel hub threads. Although
they have been tightened to the prescribed torque, they could come loose
while driving.
WARNING
If the wheel bolts are not fitted correctly they could be released while
driving leading to loss of vehicle control and serious damage.
● Only use wheel bolts which correspond to the wheel rims in question.
● Never use different wheel bolts.
● The bolts and threads should be clean, free of oil and grease and easy
to thread.
● To loosen and tighten the wheel bolts, always use the wheel brace
supplied with the vehicle.
● Loosen the wheel bolts only about one turn before raising the vehicle
with the jack.
● Never grease or lubricate wheel bolts or the wheel hub threads. Al-
though they have been tightened to the prescribed torque, they could
come loose while driving.
● Never loosen the bolted joints of wheel rims with bolted ring trims.
● If the wheel bolts are not tightened to the correct torque, they may
come loose while driving, and the bolts and rims may come out. If the
tightening torque is too high, the wheel bolts and threads can be dam-
aged.

. Tighten the bolts in diago-
nal pairs (not in a circle).
● Put the caps, trim or full hubcap back on ⇒ page 250.
WARNING
If the wheel bolts are not treated suitably or not tightened to the correct
torque then this could lead to loss of vehicle control and to a serious ac-
cident.
● All the wheel bolts and hub threads should be clean and free of oil
and grease. The wheel bolts should be easily tightened to the correct tor-
que.
● The hexagonal socket in the wheel brace should be used for turning
wheel bolts only. Do not use it to loosen or tighten the wheel bolts.

(29-36 psi / 200-250 kPa) ⇒ 
. Maximum operation time 8 minutes ⇒ .
● Disconnect the air compressor.
● If it is not possible to achieve an air pressure of 2.0 to 2.5 bar
(29-36 psi / 200-250 kPa), unscrew the tyre inflator tube from the tyre valve.
● Move the vehicle some 10 metres forwards or backwards so that the
sealant is evenly distributed in the tyre interior.
● Securely screw the compressor tyre inflator tube into the tyre valve and
repeat the inflation process.
● If the indicated pressure can still not be reached, the tyre is too badly
damaged. The tyre cannot be sealed with the anti-puncture kit. Do not con-
tinue driving. You should obtain professional assistance ⇒ 
.
● Disconnect the air compressor and unscrew the flexible inflator tube
from the tyre valve.
● When the tyre pressure is between 2.5 and 2.0 bars, immediately con-
tinue driving without exceeding 80 km/h (50 mph).
