Many people believe that they can brace their weight with their hands in a minor collision. This is not true.
Even at low speeds, the forces acting on the body in a collision are so great that occupants cannot brace themselves with their arms and hands. In a frontal collision, vehicle occupants who have not fastened their seatbelts will be thrown forward and will make unchecked contact with parts of the vehi-cle interior, e.g. the steering wheel, dash panel, or windscreen =:-Fig. 62.
The airbag system is not a substitute for the seat belts. When triggered, the airbags only provide ad-ditional protection. Airbags are not triggered in all kinds of accidents. Even if the vehicle is equipped with an airbag system, all vehicle occupants, in-

eluding the driver, must fasten their seat belt and wear it correctly while the vehicle is in motion. This reduces the risk of severe or fatal injuries in the event of an accident-regardless of whether an airbag is fitted for the seat.
Each airbag can only be triggered once. To ach-ieve best possible protection, seat belts must al-ways be worn properly. This also ensures that pro-tection is provided in accidents in which the airbag is not triggered. Any vehicle occupants not wearing a seat belt can be thrown out of the vehicle and sustain more severe or even fatal injuries as a re-sult.
11 is also important for the rear seat occupants to wear seat belts properly, as they could otherwise be thrown forwards violently in an accident. Rear passengers who are not wearing seat belts endan-ger not only themselves and the driver, but also other people in the vehicle =:-Fig. 63.

When fastened properly, seat belts hold the vehicle occupants in the correct sitting positions and con-siderably reduce the kinetic energy in the event of an accident. Seat belts also help to prevent uncon-trolled movements which could lead to severe inju-ries. In addition, wearing seat belts properly re-duces the risk of being thrown from the vehicle 64.
Passengers wearing seat belts correctly benefit greatly from the ability of the belts to reduce the ki-netic energy. The front crumple zones and other

Checklist
Using seat belts &:
../ Check the condition of all seat belts regular-ly.
../
../
Keep the seat belts clean.
Avoid allowing any foreign bodies or fluids to get on to the seat belt or latch plate or in-to the slot for the seat belt buckle.
../ Do not trap or damage the seat belt and latch plate. for example when closing the door.
passive safety features (such as the airbag sys-tem) are also designed to reduce kinetic energy. The amount of energy generated will thus de-crease, thereby reducing the risk of injury.
The examples describe frontal collisions. Of course, properly worn seat belts substantially re-duce the risk of injury in all other types of acci-dents. This is why seat belts must be fastened be-fore every trip -even if you are only planning to drive a very short distance. Ensure that all passen-gers also wear their seat belts properly.
Accident statistics have shown properly worn seat belts to be an effective means of substantially re-ducing the risk of injury and improving the chances of survival in a serious accident. Furthermore, properly worn seat belts improve the protection provided by airbags in the event of an accident. This is why wearing a seat belt is a legal require-ment in most countries.
Although the vehicle is equipped with airbags, the seat belts must be fastened and worn. For exam-ple, the front airbags will only be triggered in cer-tain types of frontal collision. The front airbags will not be triggered during minor frontal collisions, mi-nor side collisions, rear collisions. rolls or accidents in which the airbag trigger threshold in the control unit is not exceeded.
Therefore. always wear your seat belt and ensure that your passengers have fastened their seat belts properly before you drive off. ../ Never remove, modify or repair the seat belt or any part of the belt fixture system.
../ Always fasten the seat belt correctly before every journey and keep it fastened while the vehicle is in motion.
Twisted seat belt
If it is difficult to remove the seat belt from the belt guide, the seat belt may have become twisted if it was returned too quickly into the side trim panel:
• Take hold of the latch plate then slowly and carefully pull out the seat belt.
• Untwist the seat belt and guide it back slowly
Sitting correctly and safely

Fasten the seat belt even if you are unable to undo the twist. However, the twist should not be in part of the seat belt that comes into direct contact with the body. The twist should be corrected immediate-ly by a qualified workshop.
A WARNING
Using seat belts incorrectly Increases the risk of severe or fatal Injuries.

r-T'n First read and observe the introductory L-Wl infonmation and safety warnings & on page 79.
Seat belts only provide an optimum level of protec-tion during an accident when they are routed cor-rectly. Correct seat belt routing reduces the risk of severe or fatal injuries. Correct seat belt routing al-so holds the vehicle occupants in position so that an inflating airbag can offer the maximum level of protection. Therefore you must always fasten your seat belt and ensure that the seat belt routing is correct.
Assuming an incorrect sitting position can cause severe or fatal injuries 61, Adjusting the seat position.
Correct seat belt routing
• The shoulder part of the seat belt must always lie on the centre of the shoulder, never across the neck, over or under the arm or behind the back.
• The lap part of the seat belt must always lie across the pelvis, never across the stomach.
• The seat belt must always lie flat and snugly on the body. Tighten the belt if necessary.
For pregnant women, the seat belt must be posi-tioned evenly over the chest and as low as possi-ble over the pelvis. it must lie flat so that no pres-sure is exerted on the lower body-this applies for the entire course of the pregnancy =>Fig. 68.
Correct seat belt routing according to height
The following equipment can be used to adjust the seat belt routing:
• Belt height adjuster for the front seats =>page 86.
• Height-adjustable front seats =>page 61.
A WARNING
Incorrect seat belt routing can cause severe Injuries In the event of an accident or a sud-den braking or driving manoeuvre.
• The seat belts only offer best protection when the backrests are in an upright position and the seat belts have been fastened proper-ly.
• The seat belt itself or a loose seat belt can cause serious injuries if the seat belt shifts from harder body parts In the direction of softer body parts (e.g. stomach). .,.

A WARNING !Continued)
• The belt webbing should not lie over hard or fragile objects, such as glasses, pens or keys.
• Never use seat belt clips, retaining rings or similar items to alter the seat belt routing.
m If a person's physical build prevents them L.!:J from routing the seat belt properly, contact a qualified workshop to find out about any special modifications so that the seat bells and airbags can provide the optimum level of protection. Volks-wagen Commercial Vehicles recommends using a Volkswagen Commercial Vehicles dealership for this purpose. The seat belt height adjusters for the front seats can be used to adjust the position of the seat belt on the shoulder so that it can be fastened properly:
• Push and hold the upper part of the shoulder belt guide 69.
• Push the shoulder belt guide up or down so that the seat belt lies over the middle of the shoul-der 85, Seat belt routing.
• Let go of the shoulder belt guide.
• Pull sharply on the seat bell to check whether the shoulder belt guide is engaged securely.
Never adjust the seat belt height when the ve-hicle is in motion. Automatic belt retractor and belt tensioner
r--f"'n First read and observe the introductory L-W.I information and safety warnings & on page 79.
The seat belts in the vehicle are part of the vehicle safety concept 91 and include the follow-ing important functions:
86 Before the journey
Automatic belt retractor
Every seat belt is equipped with an automatic belt retractor on the shoulder part of the belt. Full free-dom of movement is made possible when the shoulder belt is pulled slowly or when the vehicle is travelling at normal speeds. However, if the belt is IIJ>

pulled out quickly or during sudden braking, during travel in mountains or bends and during acceleration, the automatic belt retractor is locked.
Belt tensioners
The seat belts for the front seat occupants are equipped with belt tensioners.
The belt tensioners are activated by sensors dur-ing severe frontal, side and rear collisions. They tighten the seat belts against the direction in which they are pulled. Any slack in the seat belt is retrac-ted, which can reduce the passenger's movement forwards or in the direction of the impact. The belt
tensioner works together with the airbag system. The belt tensioner will not be activated if the vehi-cle rolls over if the combined curtain and side air-bags are not activated.
A fine dust may be produced when the airbags are triggered. This is quite normal and does not mean that there is a fire in the vehicle.
W All safety requirements must be observed L!.J when the vehicle or components of the sys-tem are scrapped. Qualified workshops are familiar with these requirements 87. Service and disposal of belt tensioners
r-f'n First read and observe the introductory L-J,:.U information and safety warnings & on page 79.
Seat belts may become damaged during any work on the belt tensioners or while removing or refitting any vehicle parts in conjunction with any other re-pair work. This damage will not always be noticea-ble. The consequence may be that the belt ten-sioners could function incorrectly, or not function at all, in the event of an accident.
Regulations must be observed to ensure that the effectiveness of the belt tensioner is not reduced and that removed parts do not cause any injuries or environmental pollution. Qualified workshops are familiar with these requirements.

Description and function of the airbags
r-('n First read and observe the introductory l..-lc:.l.l information and safety warnings & on page 87.
The airbags can protect vehicle occupants during frontal and side collisions by reducing their move-ment in the direction of the collision.
When an airbag is triggered, it is inflated by a gas generator. This causes the airbag covers to break, and the airbags inflate forcefully to cover their de-ployment zones within milliseconds. Once a vehi-cle occupant wearing a seat belt starts to sink into the inflated airbag, the gas inside the airbag starts to escape to cushion the occupant and slow down their movement. This can reduce the risk of severe and fatal injuries. The triggering of the airbag will not always prevent other injuries such as swelling, bruising and grazing. The deployment of the airbag can also produce frictional heat.
Airbags provide no protection for the arms or lower body.
The most important factors for triggering the airbag are the type of accident, the angle of impact, the vehicle speed and the type of object with which the vehicle collides. Therefore, visible damage to the vehicle does not always mean that the airbag should have been triggered.
90 Before the journey
Whether or not the airbag triggers is determined by the vehicle deceleration rate caused by the colli-sion and registered by the electronic control unit. If this rate is below the reference value programmed into the control unit, the airbags will not be trig-gered, even though the vehicle may be badly dam-aged as a result of the collision. Vehicle damage, repair costs or even the Jack of vehicle damage in an accident do not necessarily give an indication of whether an airbag should inflate or not. it is not possible to define a range of vehicle speeds and reference values, since the circumstances will vary considerably between one collision and another. it is therefore impossible to cover every possible kind and angle of impact that would trigger the airbags. Important factors in the triggering of the airbag in-clude the nature (hard or soft) of the object that the vehicle hits, the angle of impact, and the vehicle speed.
Airbags only serve as a supplement to the three-point seat belt in some accident situations when the vehicle braking is sufficient to trigger the air-bags. Airbags can only be triggered once and only in certain situations. The seat belts are always there to provide protection in situations in which the airbags are not triggered or have already been triggered. For example, if the vehicle collides with a further vehicle following the initial collision, or is hit by another vehicle. .,.

r-f'n First read and observe the introductory L..-.J,:.I.J Information and safety warnings & on page 87.
In conjunction with the seat belts, the front airbag system gives the front occupants additional protec-tion for the head and chest in the event of a severe frontal collision. Always keep as far away from the front airbag as possible 61. This allows the front airbags to inflate fully when triggered, thus providing maximum protection.
The front airbag for the driver is located in the steering wheel 71 and the front airbag for the front passenger is located In the dash panel 72. The airbag locations are identified by the text "AIRBAG".
The areas inside the red lines 71 and 72 are covered by the front airbags when triggered (deployment zone). You must never leave or attach any objects in these areas &. The fac-tory-fitted accessories, such as the base plate for

A DANGE;R (Continued) --
• No other people, animals or objects may be carried between the occupants of the front seats and the alrbag deployment zone. Make sure that children and passengers also keep to this rule.
• Do not attach any objects, e.g. mobile nav-igation devices, to the windscreen above the front alrbag on the front passenger side.
• Do not cover or stick anything on the steering wheel hub or the soft plastic surface of the alrbag unit In the dash panel on the front passenger side, and do not modify them In any way.
