Limitations for work on the chassis
General
General
When planning bodybuilding work, it is important to know at an early stage what is
permitted and not permitted for a vehicle.
This document describes some of the limitations that apply when fitting extra equip-
ment and during bodywork.
More information can be found in the document for each application:
• Example of a search term: Box trucks.
• Examples of filters:
– Type of work: Bodywork assembly.
– Type of product: Tipper trucks.
More information on locating chassis components can be found on the vehicle’s
chassis drawing, ICD (Individual Chassis Drawing).
IMPORTANT!
Follow legal requirements regarding what modifications are permitted on the vehi-
cle.
More information on what modifications are permitted on a vehicle can be found in
the document “Modifying Scania components and systems covered by a certificate”.

Blocking of moving components
Blocking of moving components
WARNING!
Ensure that no loose objects can fall down from the load. Also ensure that, for exam-
ple, load securing equipment is fastened. Falling objects may obstruct moving com-
ponents such as the gearbox’s gear shift linkage, propeller shafts and power take-
offs.
Hot components
IMPORTANT!
Hot components require a safety clearance or heat shield to protect components
which are not heat resistant.
More information is found in the document Risk of fire and damage in connection
with hot components.

IMPORTANT!
The design of the bodywork must not prevent or impair the following:
• Maintenance.
• Repairs.
• Lifting the engine, gearbox, shafts or other components in and out.
• Tilting the cab.

Ventilating valve on the automatic gearbox
Ventilating valve on the automatic gearbox
Water must be prevented from entering the ventilating valve on the automatic gear-
box.
Move the ventilating valve to another location if there is a risk of it being splashed
with water, e.g. on fire engines, military vehicles and refuse collection trucks.
When moving the ventilating valve, the following applies:
• Use an adapter that converts the original connection from M10 to M12.
• Use a hose with internal diameter of at least 9.5 mm.
• Position the ventilating valve in a location which is well above the water level.
Note:

The radar’s field of view must not be obstructed
The radar’s field of view must not be ob-
structed
WARNING!
The radar covers must be protected during re-painting or anti-corrosion treatment.
The vehicle's radar, located at the front and on the sides, is very sensitive to interfer-
ence and must not be covered or painted over. Its functionality depends on the thick-
ness of the radar cover and its material properties. Obstructing the radar's field of
view by, for example, covering with paint or stickers risks negatively affecting the
vehicle's safety functions, resulting in unwanted braking or no braking.

Location of radar.
WARNING!
• The radar’s field of view must not be blocked by, for example, the frontal protec-
tion system or auxiliary lights.
• Snow or other obstructions can reduce the radar’s field of view.
• It is not permissible to move the radar.
• If the radar is temporarily removed from its bracket, the plastic bushings must be
renewed before the radar is refitted.

The radar’s field of view must not be obstructed
Systems that are affected by the radar:
• Option Advanced emergency braking (AEB) (variant code 4335A). AEB in vehi-
cles with front-mounted equipment may be switched off before the vehicle is driv-
en away. The system can only be switched off momentarily, and must therefore
be switched off every time the engine is started.
• Option Adaptive cruise control (variant code 3583A) depends on the radar to
work. If the radar’s field of view is blocked, AICC should not be used.
More information on AEB can be found in the Driver’s Manual.

The radar’s field of view must not be obstructed
An extended area must be left radar free if there is a risk of the area shrinking during
operation, for example due to dirt, snow or ice. The size of this area depends on the A B
prevailing conditions in which the vehicle will be operated and also on how the o
structure is designed, e.g. whether there are compartments or openings where snow 25

WARNING!
• Obstructing the camera’s field of view risks negatively affecting the vehicle's
safety functions, resulting in unwanted braking or no braking.
• It is not permissible to move the camera.
The camera has safety-critical functions. Auxiliary equipment on the front of the cab

and stickers on the windscreen must not obstruct the camera. Blocking the camera
can impair functionality and may cause the camera to shut down. Camera location.
A camera is fitted in vehicles with any of the following options:
• Advanced emergency braking (AEB) (variant code 4335A).
• Adaptive cruise control (variant code 3583A).
• Scania lane departure warning (LDW1(variant code 3601A).
The camera scans the following area:
• Horizontal field of view: ±25° (calculated from the windscreen) 14°
• Vertical field of view: +14°/-21° (calculated from the horizontal plane).

The rain sensor's and light sensor’s field of view must not be obstructed
The rain sensor's and light sensor’s field of
view must not be obstructed
The Rain sensor (variant code 5121A) and Automatic dipped beam (variant code
5058A) options comprise a combined rain sensor and light sensor. Both options have
safety-critical functions. The field of view of the sensors must not be obstructed by
auxiliary equipment on the front of the cab or stickers on the windscreen. A blockage
can impair functionality and may cause the sensors to shut down.
The sensors are located in front of the driver area on the lower edge of the wind-
screen; see illustration. Leave 100 mm free space around the sensors.

WARNING!
Location of rain sensor and light sensor.
Obstructing the rain sensor's and light sensor’s field of view risks negatively affect-
ing the vehicle’s safety functions.

Air intakes must not be obstructed
Air intakes must not be obstructed
WARNING!
If the air intakes are obstructed, there is a risk of the engine overheating.
The air intakes have safety-critical functions. Auxiliary equipment on the front of the
cab must not block the radiator or the engine's air intake on the front grille panel. This
can cause an increase in temperature and may overheat the engine.
