increases the ability of the supplemental airbags to do their job in a
collision. For this reason, wearing a safety belt is legally required in
most countries including much of the United States and Canada .
Although your Audi is equipped with airbags, you still have to wear
the safety belts provided. Front airbags, for example, are activated
only in some frontal collisions. The front airbags are not activated in
all frontal collisions, in side and rear collisions, in roll overs or in
cases where there is not enough deceleration through impact to the
front of the vehicle. The same goes for the other airbag systems in
your Audi . So, always wear your safety belt and make sure every­
body in your vehicle is properly restrained!
•
Important safety instructions about safety
belts
Safety belts must always be correctly positioned across the strongest bones of your body.
-Always wear safety belts as illustrated and described in
this chapter.
- Make sure that your safety belts are always ready for use
and are not damaged.
& WARNING
Not wearing safety belts or wearing them improperly increases
the risk of serious personal injury and death. Safety belts can work
only when used correctly.
• Always fasten your safety belts correctly before driving off and
make sure all passengers are correctly restrained.
• For maximum protection, safety belts must always be posi­
tioned properly on the body.
• Never strap more than one person, including small children,
into any belt.
& WARNING (continued)
• Never place a safety belt over a child sitting on your lap.
• Always keep feet in the footwell in front of the seat while the
vehicle is being driven.
• Never let any person ride with their feet on the instrument
panel or sticking out the window or on the seat.
• Never remove a safety belt while the vehicle is moving. Doing
so will increase your risk of being injured or killed.
• Never wear belts twisted.
• Never wear belts over rigid or breakable objects in or on your
clothing, such as eye glasses, pens, keys, etc., as these may cause
injury.
• Never allow safety belts to become damaged by being caught
in door or seat hardware.
• Do not wear the shoulder part of the belt under your arm or
otherwise out of position .
• Several layers of heavy clothing may interfere with correct posi­
tioning of belts and reduce the overall effectiveness of the system.
• Always keep belt buckles free of anything that may prevent the
buckle from latching securely.
• Never use comfort clips or devices that create slack in the
shoulder belt. However, special clips may be required for the
proper use of some child restraint systems.
• Torn or frayed safety belts can tear, and damaged belt hard­
ware can break in an accident. Inspect belts regularly. If webbing,
bindings, buckles, or retractors are damaged, have belts replaced
by an authorized Audi dealer or qualified workshop.
• Safety belts that have been worn and loaded in an accident
must be replaced with the correct replacement safety belt by an
authorized Audi dealer . Replacement may be necessary even if
damage cannot be clearly seen. Anchorages that were loaded
must also be inspected.

___ s_a_ f_ e_ t-= y_ b_e_ l_ t _s _______________________________________________ _
& W ARNING (continued )
• Safety belts offer optimum protection only when the seat back
is upright and belts are properly positioned on the body.
• Always make sure that the rear seat backrest to which the
center rear safety belt is attached is securely latched whenever
the rear center safety belt is being used. If the backrest is not securely latched, the passenger will move forward with the back ­
rest dur ing sudden braking , in a sudden maneuver and especially
in a crash.
• Never attach the safety belt to the buckle for another seat.
Attaching the belt to the wrong buckle will reduce safety belt
effectiveness and can cause ser ious personal injury .
• A passenger who is not properly restrained can be ser iously
injured by the safety belt itself when it moves from the stronger
parts of the body into critical areas like the abdomen .
• Always lock the convertible locking retractor when you are
securing a child safety seat in the vehicle
=> page 222. •

& WARNING
Improperly positioned safety belts can cause serious personal
injury in an accident .
• The shoulder belt portion of the safety belt must be positioned
over the middle of the occupant's shoulder and never across the
neck or throat.
• The safety belt must lie flat and snug on the occupant's upper
body
