After fitting the wheel:
X
Tighten the wheel nuts in a crosswise pat-
tern. Observe the correct tightening torque
( Y page 357).
X Vehicles with tyre pressure control sys-
tem: push connector = into compressed-
air connection : and hold until circlip ;
engages.
X
All vehicles: fit the wheel nut cover.
X Vehicles without tyre pressure control
system: check the tyre pressure
( Y page 340).
X Vehicles with tyre pressure control sys-
tem: activate the automatic mode of the
tyre pressure control system (
X
All vehicles: the wheel nuts must be
retightened after 50 km (
Retightening the wheel nuts

WARNING
The wheels could work loose if the wheel nuts
and bolts are not tightened to the specified
tightening torque. There is a risk of accident.
Have the tightening torque immediately
checked at a qualified specialist workshop
after a wheel is changed.
! Check wheel nuts regularly for tightness.
Retighten if necessary. Replace damaged
wheel nut covers. Observe the wheel nut
tightening torques.
Observe the wheel nut tightening torque
( Y page 357).
When using new or newly-painted wheel rims,
check the tightening torque again after trav-
elling approximately 1000 to 5000 km.
You may only fill the tyres using the
compressed-air system if your vehicle has a
tyre inflator connection. The reservoir pres-
sure is too high for other connections. Pres-
sure hoses and tyres may explode when filling
using other connections.

Tyre inflator connection

To inflate the tyres: remove cap on tyre
inflator connection :.
Remove tyre inflator hose from the stow-
age compartment in the rear of the cab
( Y page 312).
Deflate at tyre inflator connection :.
If the vehicle is predominantly used on
prepared road surfaces: specified tyre
pressures must be observed.
When driving off-road and on surfaces
with minimal load-bearing capacity
(e.g. sand): lower the tyre pressure
( Y page 352).
This improves the traction of the tyres.
The self-cleaning effect of the tyres is
improved at low tyre pressure, e.g. on
greasy and wet surfaces.
