2018 AUDI A8 door lock

Drivin g
During emergency braking, your vehicle will
brake sim ilar to heavy brak ing. ESC and the
associated components (ABS, ASR, EDL)
cannot overcome the laws of physics . In cor­
ners and when road or weather cond it ions
are bad, a full b rake applicat ion ca n cause
the vehicle to skid o r the rear end to swerve,
wh ic h increases the r is k of an accident.
- If the powe r supply fa ils, you cannot set the
par king b rake if it is re leased. In th is case,
par k the vehicle on level ground and secure
it by placing the selector lever in the P posi­
tion . See an authorized Audi dea ler or a u­
thorized Audi Service Facility for assistance .
- Always take the vehicle key with you when
leaving your vehicle, even fo r a short period
of time . This applies particular ly w hen ch il­
dren rema in in the vehicle. Otherwise ch il­
dren could start the engine, release the
park ing brake or operate electrical eq uip­
ment such as powe r windows, which in­
c reases the risk of an acc ident.
- No one sho uld rema in in the vehicle when it
is locked - especially ch ild ren. Locked doo rs
make it mo re diff icu lt fo r eme rgency wor k­
ers to get into the vehicle, which puts lives
at r is k .
0) Tips
When stopping at a traffic s ignal or stopping
in c ity traffic, you can set the parking b rake
manually. The vehicle does no t have to be
he ld w it h t he br ake peda l. The parking b rake
elim ina tes the tendency to creep when a se ­
lecto r lever position is engaged . As soon as
you p ress t he accelerator pedal, the parking
brake releases automat ica lly and your vehicle
starts to move
c::, page 82.
(D Tips
- Occasiona l noises when the parking brake is
set and re leased a re normal and a re not a
cause for concer n.
- The park ing bra ke goes thro ugh a se lf-test
cycle at regular intervals when the ve hicle is
stopped. Any noises associated w ith this a re
normal.

Child safety seats
Infant seats
Babies and infants up to about one year old and
20 lbs. or 9 kg need special rearward -facing
child restraints that support the back, neck and
head in a crash .
Fig. 2 4 0 Sche matic overview: rearward-facing infant seat,
properly installed on the rear seat
• When using the vehicle safety be lt to install a
child safety seat, you must first activate the
convertible locking retractor on the safety be lt
to prevent the child safety seat from moving
¢ page 259 or install the seat using the LA TCH
attachments.
• Push the child safety seat down with your full
weight to get the safety belt really tight so that
the seat cannot move forward or sideways
more than one inch (2.5 cm).
• Secure unused safety belts on the rear seat
¢page 254 .
Infants up to about one year (20 lbs. or 9 kg) are
best protected in spec ial infant carriers and child
safety seats des igned for their age group . Many
experts believe that infants and small children
should ride only in spec ial restraints in which the
chi ld faces the back of the veh icle. These infant
seats support the baby 's back, neck and head in a
crash
c!;> fig . 240.
The airbag on the passenger side makes the front
seat a potentially dangero us p lace for a child to
ride. The front seat is not the safest place for a
chi ld in a forward -facing child seat . It is a very
lL dangerous place for an infant or a larger child in t:0
;:::: a rearward-facing seat.
