Flat tire
Mounting the new wheel
1Wheel bolt for 18", 19", 20" and 21"
light alloy wheels
2Wheel bolt for Minispare wheel (locat-
ed in vehicle tool kit (
page 490))
Clean contact surfaces of wheel and
wheel hub.
Guide spare wheel onto the alignment
bolt and push it on the wheel hub.
Insert wheel bolts and tighten them
slightly.
Unscrew the alignment bolt, install last
wheel bolt and tighten slightly.
!Wheel bolts2 must be used when mount-
ing the Minispare wheel. The use of any wheel
bolts other than wheel bolts2 for the Minispare
wheel will damage the vehicle’s brakes.
!To avoid paint damage, place wheel flat
against hub and hold it there while installing first
wheel bolt.
Warning!G
Always replace wheel bolts that are
damaged or rusted.
Never apply oil or grease to wheel bolts.
Damaged wheel hub threads should be
repaired immediately. Do not continue to
drive under these circumstances! Contact
an authorized Mercedes-Benz Light Truck
Center or call Roadside Assistance.
Incorrect wheel bolts or improperly tight-
ened wheel bolts can cause the wheel to
come off. This could cause an accident.
Make sure to use the correct wheel bolts.
Warning!G
Only use genuine Mercedes-Benz wheel
bolts. Other wheel bolts may come loose.
Do not tighten the wheel bolts when the
vehicle is raised. Otherwise the vehicle
could fall off the jack.

1-5Wheel bolts
Tighten the five wheel bolts evenly, fol-
lowing the diagonal sequence illustrat-
ed (1 to 5), until all bolts are tight.
Observe a tightening torque of
110 lb-ft (150 Nm).
Store jack and all other vehicle tool kit
items back into the storage well.

changing a wheel. The wheels could come
loose if they are not tightened to a torque of
110 lb-ft (150 Nm).
iThe removed road wheel cannot be stored in
the spare wheel well under the cargo compart-
ment floor, but should be transported in the car-

Do not activate the tire inflation pressure moni-
tor until a full size wheel/tire with functioning
sensor has been placed back into service on the
vehicle.
