Anti-Theft Wheel Nuts - Mercedes-Benz 2006 SLR McLaren Operator's Manual

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.
Warning!
Have the tightening torque checked after
changing a wheel. Wheels could become
loose if not tightened with a torque of
95 lb-ft (130 Nm).
Only use Genuine Mercedes-Benz wheel
bolts specified for your vehicle's rims.
For information on wheel change, see the
"Practical hints" section ( page 351).

Warning!
Pull the parking brake lever up as many
notches as possible and move the gear se-
lector lever to position P, before loosening
the wheel bolts. Otherwise the vehicle may
move and cause an accident and/or serious
personal injury.
!
Do not use air tools, such as an impact
wrench, when installing or removing
the anti-theft wheel nuts. An impact
wrench can damage the anti-theft
wheel nuts and the wheel nut key, or
cause them to malfunction.

Store wheel bolts and anti-theft wheel
nuts not currently in use in a safe place
to avoid damage to the threads.
