2018 AUDI TT ROADSTER ABS

Child safety
The vehicle 's safety belts alone will not fit most
chi ldren until they are at least 4
ft 9 in (57 in/
1.45 m) tall and weigh about 80 lbs (36 kg) .
Booster seats raise these children up so that the
safety belt will pass properly over the stronger
parts of their bodies and the safety belt can help
protect them in a crash .
.. Do not use the convertible locking retractor
when using the vehicle 's safety belt to restrain
a child on a booster seat .
.. The shoulder belt must lie as close to the cen­
ter of the child's collar bone as poss ible and
must lie flat and s nug on the upper body. It
must never lie across the throat or neck. The
lap belt must lie across the pelvis and never
across the stomach or abdomen . Make sure the
belt lies flat and snug . Pull on the belt to tight ­
en if necessary .
Chi ldren up to at least 8 years old (over 40 lbs or
18 kg) are best protected in chi ld safety seats de­
signed for their age and weight . Experts say that
the skeleta l structure, particularly the pelvis, of
these children is not fully developed, and they
must not use the vehicle safety belts without a
suitable child restraint.
It is usually best to put these children in appro­
priate booster seats. Be sure the booster seat
meets all applicable safety standards .
Booster seats raise the seating position of the
child and repos ition both the lap and shoulder
parts of the safety be lt so that they pass across
the child's body in the right places. The rout ing of
the belt over the child's body is very important
for the child's protection, whether or not a boos­
ter seat is used.
Never use the lap belt portion of the vehicle's
safety belt alone to restrain any child, regardless
of how big the child is. Always remember that
chi ldren do not have th e pronounced pelvic struc­
ture required fo r the proper function of lap belt
port ion of the vehicle's three point lap and
shoulder belts. The child's safety absolute ly re ­
quires that a lap belt portion of the safety belt be
fastened snugly and as low as possible around the pelvis . Never let the lap belt portion of the
224
safety belt pass ove r the child's stomach or abdo­
men .
In a crash, airbags must inflate w ith in a blink of
an eye and with considerable force. In order to do
its job, the airbag needs room to inflate so that it
will be there to protect the occupant as the occu ­
pant moves forward into the airbag .
A ve hicle occ upant who is o ut of pos it io n and too
close to the airbag gets in the way of an inflating
airbag . When an occupant is too close, he or she
will be struck vio lent ly and w ill rece ive serious or
possibly even fatal injury.
In order for the airbag to offer protection, it is
important that all vehicle occupants, especially
any ch ildren, who m ust be in the front seat be­
cause of exceptional c ircumstances, be properly
restrained and as far away from the airbag as
possible . By keeping room between the child 's
body and the front of the passenger compart­
ment, the a irbag can inflate completely and pro­
v ide supplementa l protection in certa in frontal
collisions.
_& WARNING
Not using a booster seat, using the booster
seat improperly, incorrect ly installing a boos­
ter seat or using the ve hicle safety belt im­
properly increases the r isk of serious personal
injury and death in a collision or other emer­
gency situation. To he lp reduce the risk of se­
rious personal injury and/or death:
- The shou lder belt must lie as close to the
center of the child' s collar bone as possible
and must lie flat and snug on the upper
body. It must never lie across the throat or
neck. The lap belt must lie across the pelvis
and never across the stomach or abdomen.
Make sure that the belt lies flat and snug .
P ull on the belt to tighten if necessary .
- Failur e to properly route safety belts over a
child's body will cause severe injuries in an
accident or other emergency situation
¢page 187.
- The rear side of the child safety seat should
be positioned as close as possible to the
backrest on the ve hicle seat .
-

Wheels
Because the spare tire* is differ­
ent from the regular tires instal­ led on the vehicle (such as winter
tires or wide tires), only use the
spare tire* temporarily in case of
emergency and drive carefully
while it is in use. It should be re­ placed with a regular tire as soon
as possible.
Applies to: vehicles with all wheel
drive: all four wheels must be
equipped with tires that are the
same brand and have the same
construction and tread pattern so
that the drive system is not dam­
aged by different wheel speeds.
For this reason, in case of emer­
gency, only use a spare tire* that
is the same circumference as the
regular tires.
& WARNING ~ -
-Only use tire/rim combina­
tions and suitable wheel bolts
that have been approved by
Audi. Otherwise, damage to
the vehicle and an accident could result.
-For technical reasons, it is not
possible to use tires from oth­
er vehicles - in some cases,
you cannot even use tires from
the same vehicle model.
252
-Make sure that the tires you
select have enough clearance
to the vehicle. Replacement
tires should not be chosen simply based on the nominal
size, because tires with a dif­
ferent construction can differ greatly even if they are the
same size. If there is not
enough clearance, the tires or
the vehicle can be damaged and this can reduce driving
safety and increase the risk of
an accident.
-Only use tires that are more
than six years old when abso­
lutely necessary and drive
carefully when doing so.
-Do not use run-flat tires on
your vehicle. Using them when not permitted can lead to ve­
hicle damage or accidents.
- If you install wheel covers on
the vehicle, make sure they al­ low enough air circulation to
cool the brake system. If they
do not, this could increase the
risk of an accident.

Tire pressure monitoring system
(J_) General notes
Each tire, incl uding the spare (if provided),
should be checked month ly when co ld and inflat­
ed to the inf lation pressure recommended by the
ve hicle manufacturer on the vehicle placard or
tire inflat ion pressure label. (If your vehicle has
tires of a d ifferent s ize tha n the s ize indicated on
the veh icle placa rd or t ire inflation pressure la­
be l, you s hou ld determine the prope r tir e infla­
tion pressure fo r th ose tires).
As an added safety feature, your ve hicle has been
equ ipped w ith a t ire pressu re monito ring system
(TPMS) that ill uminates a low tire p ress ure tell­
tale whe n one or more of yo ur t ires is sign ificant ­
l y unde r-infla ted. Accord ingly, whe n the low tire
p ressure tellta le illuminates, yo u should stop and
check your tires as soon as possible, and inflate
them to the proper press ure. D riving on a signifi ­
cantly under-inflated tire causes the tire to ove r­
h eat and can lead to t ire failure. Under-inflation
a lso reduces fuel efficiency and ti re tread life,
and may affect the veh icle's handling and stop­
p ing ability .
P lease note that the TPMS is not a substitute for
proper tire maintenance, and it is the driver's re­
sponsib il ity to ma inta in correct tire pressure,
even if u nder-inflation has not reached t he leve l
to tr igger illum inat io n of t he TPM S low tire p res ­
sure telltale.
Your veh icle has also been equ ipped w ith a TPMS
malfunct ion ind icator to indicate when the sys­
tem is not operat ing properly. The TPMS ma l­
f u nction ind icator is combined w ith the low tire
p ressure tellta le. Whe n the system det ects a
mal function, the te lltale wi ll flash fo r approxi ­
mate ly one mi nute and then remain continuous ly
illum inated. This sequence will continue upon
subseq uent ve hicle start-ups as long as the ma l­
function ex ists .
W hen t he malfunctio n indicator is ill uminated,
the system may not be ab le to detect or signa l
low t ire press ure as intended. TPMS ma lfunctions
may occur for a var iety of reasons, including the
Wheels
insta llation o f replacement or alternate tires or
whee ls on the vehicle that prevent the TPMS
from functioning p roperly . Always check the
TPMS ma lfunction te lltale after replac ing one or
more tires or wheels on you r vehicle to ensure
t h at the rep lacement or a lternate tires a nd
wheels allow t he TPMS to continue to function
prope rly.
If the Tire Pressure Monitoring System
indicator appears
Applies to: vehicles with Tire Pressure Monitoring System in­
dicator
The tire pressure indicator in the instrument
cluster informs you if the tire pressure is too low
or if there is a system malfunction.
U sing the ABS se nsors, the t ire pressure monitor­
ing system compares the tire tread c ircumfer­
ence and v ibration characterist ics of the ind ividu­
al tires. If the pressu re changes in one o r more
t ir es, th is is indica ted in the Info tainment sys tem
display wi th an indica to r li ght
ti] and a message.
If only one ti re is affected, the location of tha t
tire will be indicated.
T he tire press ures mus t be store d in the Infota in­
me nt system agai n ea ch t ime t he p ressures
change (switching between partia l and full load
pressure) or after c hanging or replacing a tire on
yo ur vehicle
¢ page 262 . The tire pressure moni ­
toring system on ly monitors the tire pressure you
have stored. Refer to the t ire pressure label for
the recommended t ire pressure for your vehicle
¢ page 254, fig . 190 .
Tire tread c ircumference and vibration character ­
istics can change and cause a tire pressu re warn­
i ng if:
- the ti re pressure in one or more tires is too low
- the tire has str uctural damage
