steering inoperative. Before the engine can be started, the normal steering 
operation must be restored. 
 
5.3.1.2. When the device to prevent unauthorized use is set to act, it shall not be possible 
to prevent the device from functioning. 
 
5.3.1.3. The device to prevent unauthorized use must continue to meet the requirements 
of paragraphs 5.2.11., 5.3.1.1., 5.3.1.2. and 5.3.1.4. after it has undergone 2,500 locking cycles in each direction of the wear producing test specified in 
Part 1 of Annex 2 to this Regulation. 
 
5.3.1.4. The device to prevent unauthorized use shall, in its activated position, satisfy 
one of the following criteria: 
 
5.3.1.4.1. It shall be strong enough to withstand, without damage to the steering 
mechanism likely to compromise safety, the application of a torque of 300 Nm 
about the axis of the stee ring spindle in both directi ons under static conditions. 
 
5.3.1.4.2. It shall incorporate a mechanism designed to yield or slip, such that the system 
will withstand, either continuously or inte rmittently, the application of a torque 
of at least 100 Nm. The locking system must still withstand the application of this torque after the test specified in Part 2 of Annex 2 to this Regulation. 
 
5.3.1.4.3. It shall incorporate a mechanism designe d to permit the steering wheel to rotate

 - 12 -  
5.3.2.4. It shall not be possible fo r the transmission or brakes to be blocked inadvertently 
when the key is in the lock of the device to prevent unauthorized use, even if the 
device preventing starting of the engine has come into action or been set to act. 
This does not apply wherever the requi rements of paragraph 5.3.2. of this 
Regulation are met by devices used for a nother purpose in ad dition and the lock 
under the conditions above is necessary  for this additional function (e.g. 
electrical parking brake). 
 
5.3.2.5. The device to prevent unauthorized use shall be so designed and constructed that 
it remains fully effective even after some  degree of wear as a result of 2,500

(i) of intrusions into the vehicle, e.g. passenger compartment control, 
window glass control, breakage of any glazed area, or 
(ii) of attempted vehicle theft,  e.g. inclination sensor 
 
are allowed, taking account of measures to prevent any unnecessary sounding of 
the alarm (= false alarm, see paragraph 6.3.1.2. below). 
 
Insofar as these additional sensors gene rate an alarm signal even after an 
intrusion has occurred (e.g. by breakage  of a glazed area) or under external 
influences (e.g. wind), the alarm signa l, activated by one of the above- 
 - 16 - mentioned sensors, shall be activated not more than 10 times within the same 
activation period of the VAS. 
 
In this case the activation period shall be limited by the authorized unsetting of the system as a result of the vehicle user's action. 
 
Some kinds of additional sensors, e.g. passenger compartment control 
(ultrasonic, infrared) or inclinati on sensor, etc., may be intentionally 
deactivated.  In this case, separate deliberate action must be taken each time before the VAS is set.  It must not be possible to deactivate the sensors while the 
alarm system is in a set state. 
 
6.3.1.2. Safety against false alarm 
 
6.3.1.2.1. By adequate measures, e.g.
