3. Pump up the tire. Inflate the tires while
the engine is running and with
maximum pressure in the air
reservoirs.
4. Refit the protective rubber cap to the
tire inflating connection after the tire
has been inflated and store the hose.
Check as soon as possible that the
tires have the correct pressure using
a pressure gauge. See
Tire Pressure
Table (Imperial) on page 113 or Tire
Pressure Table (Metric) on page
114 .
NOTE
The entire air pressure system of
the vehicle can be filled with air
from an outside source using the
tire inflating connection. When
doing this, check that the system
pressure is correct using the air
pressure gauge.
Towing
It is possible to install a towing eye behind
the grille.
Always use a towing bar when towing.
Departure from this rule is only allowed in
emergencies.
When towing, the fault message "Engine
management fault" may appear in the
master display when the ignition is turned
on.
NOTE
The maximum permissible vehicle
speed, weight, and distance vary per
country.
WARNING
Do not tow the vehicle when fully load-
ed or with a drawn vehicle attached.
Being Towed by Another Vehicle
WARNING
When the engine is not running, there
is no power steering and no air is sup-
plied to the braking system. If the serv-
ice brake is applied or in the case of
air leakage, the parking brake might
be applied.
WARNING
The towed vehicle can be located
asymmetrically (left or right) behind the
tractor. Towing may not take place at
an angle larger than 20° with the vehi-
cle centerline.
Keep in mind the following tips when being
towed by another vehicle:
• To clear the towing eyes, the black
grid must be removed from the
lower grille by turning the
attachment screws a quarter turn.
• Always fix the tow rod with its
original attachment pin (part of the
vehicle tool kit) in the towing eyes.
