If your vehicle is driven at the
wrong 5th wheel height, mal-
functions may occur in the ve-
hicle. You may have height
problems.. The vehicle must
be driven at the correct fifth
wheel height.
Apply the following steps to uncouple the
semi-trailer with the tractor:
•
If the vehicle is equipped with serv-
ice type brake chambers, apply the
parking brake after checking the
brake drum. Never apply the parking
brake when the brake drums are
very hot. (The drum may crack.)
•
If the vehicle has a hand-brake type
brake, put a wheel chock in front of
the vehicle. Apply the handbrake.
•
Disconnect the brake air lines, the
brake will be applied automatically.
Disconnect the semi-trailer electrical
connections.
•
Lower the mechanical landing gear
of semi-trailer (use high speed).
When the mechanical landing gear
feet or wheels touch the ground,
switch the mechanical landing gear
crank handle to low-speed position
to raise the semi-trailer.
•
Unlock the fifth wheel lock. Separate
the tractor from the semi-trailer
about 500 mm by slowly moving the
tractor forward. Lower the level of
the rear suspension airbags of the
tractor and leave the semi-trailer's
bottom.
To ensure that that the king
pin is locked properly, engage
the first gear of the tractor,
and press the gas pedal, when
you are slowly releasing the
clutch, you will feel that the
tractor strives to move the se-
mi-trailer, this indicates that
the connection is made pro-
perly. During the travel, this
connection must be checked
carefully to prevent separa-
tion of the semi-trailer from
the tractor accidentally.

5.3. Cautions During the Parking and
Stopping
•
Involuntary trailer movements, un-
stable posture and insufficient
safety at night may occur serious
accidents and injuries.
•
Use the parking brake and wheel
chocks while stopping.
•
If you are going to park the vehicle
in a public traffic area, you must use
the necessary marking plate in ac-
cordance with legal regulations.
5.4. Reversing Camera
Your vehicle may optionally have a cov-
ered camera system connected to the
reversing signal. In the covered system,
the reverse signal triggers a solenoid
valve and the cover opens and closes.
