Anti-theft wheel nuts
Your vehicle is equipped with anti-theft
wheel nuts that prevent the theft of your
vehicle’s wheels.
1 Anti-theft wheel nut
2 Wheel nut key
Removing anti-theft wheel nuts
̈ Unscrew anti-theft wheel nut 1 using
wheel nut key 2.
̈ Replace anti-theft wheel nut 1 with
one of the regular wheel bolts.
̈ Fasten the wheel bolt and tighten it
with a torque wrench to a tightening
torque of 95 lb-ft (130 Nm).
Warning! G
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.
Warning! G
Pull the parking brake lever up as many
notches as possible and move the gear se-
lector lever to park position P, before loos-
ening 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.
