weight AUDI S4 2018 Owner's Manual

Child safety
-Never put the forward-facing child restraint
up, against or very near the instrument pan­
el.
- Always move the front passenger seat to
the highest position in the up and down ad­
justment range and move it back to the
rearmost position in the seat's fore and aft
adjustment range, as far away from the air­
bag as possible, before installing the for­
ward-facing child restraint.
- Always make sure that the safety belt upper
anchorage is behind the child restraint and
not next to or in front of the child restraint
so that the safety belt will be properly posi­
tioned.
- Make sure that the
PASSENGER AIR BAG
OFF~ ; light comes on and stays on all the
time whenever the ignition is switched on.
A WARNING
Rearward-facing child restraints:
- A child in a rearward-facing child safety seat
installed on the front passenger seat will be
seriously injured and can be killed if the
front airbag inflates -even with an Ad­
vanced Airbag System.
- The inflating airbag will hit the child safety
seat or infant carrier with great force and
will smash the child safety seat and child
against the backrest, center armrest, door
or roof .
- Always be especially careful if you must in­
stall a rearward facing child safety seat on
the front passenger seat in exceptional cir­
cumstances .
- Make sure that the
PASSENGER AIR BAG
OFF~; light comes on and stays on all the
time whenever the ignition is switched on.
- If the
PASSENGER AIR BAG OFF~; light
does not come on and stay on, immediately
install the rear-facing child safety seat in a
rear seating position and have the airbag
system inspected by your Audi dealer .

· Activating the convertible locking retractor
Use the convertible locking retractor to secure a
child restraint.
Always heed the child safety seat manufacturer 's
instructions when installing a child restrain t in
your vehicle . To activate the convertible locking
retractor:
.. Place the child restraint on a seat, preferably
on the rear seat .
.. Slowly pull the belt all the way out.
.. Route it around or through the child restraint
belt path
~ ,&. .
.. Push the child safety seat down with your full
weight to get the safety belt really tight.
.. Insert the belt tongue into the buckle for that
seating position.
.. Guide the safety belt back into the retractor un­
til the belt lies flat and snug on the child safety
seat.
.. You should hear a "clicking" noise as the belt
winds back into the inertia reel. Test the con ­
vertible locking retractor by pulling on the belt.
You should no longer be able to putt the belt
out of the retractor. The convertible locking re­
tractor is now activated .
.. Make sure that the red release button is facing
away from the child restraint so that it can be
unbuckled quickly.
.. Pull on the belt to make sure the safety belt is
properly tight and fastened so that the seat
cannot move forward or sideways more than
one inch (2 .5 cm) .
A WARNING
Using the wrong child restraint or an improp­
erly installed child restraint can cause serious
personal injury or death in a crash.
- Always make sure that the safety belt re­
tractor is locked when installing a child
safety seat. An unlocked safety belt retrac­
tor cannot hold the child safety seat in place
during normal driving or in a crash.
- Always buckle the child safety seat firmly in
place even if a child is not sitting in it. A
loose child safety seat can fly around during
a sudden stop or in a crash.

U.S. DOT Tire Identification
Number (TIN)
T his is the tire's "serial number".
It begins with the letters "DOT"
and indicates that the tire meets
all federal standards. The nex t
two numbers or letters indicate
the plant where it was manufac­
tured, and the last four numbers represent the week and year of
manufacture. For example,
DOT ... 2216 ...
means that the tire was produced
in the 22nd wee k of 2016. The

Tires and vehicle load limits
There are limits to the amount of
load or weight that any vehicle
and any tire can carry. A vehicle
that is overloaded will not handle
well and is more difficult to stop.
Overloading can not only lead to
loss of vehicle control, but can al­
so damage important parts of the
vehicle and can lead to sudden
tire failure, including a blowout and sudden deflation that can
cause the vehicle to crash.
Your safety and that of your pas­ sengers also depends on making
sure that load limits are not ex ­
ceeded. Vehicle load includes ev­
erybody and everything in and on
the vehicle. These load limits are
technically referred to as the vehi­ cle's
Gross Vehicle Weight Rat­
ing
("GVWR").
The "GVWR" includes the weight
of the basic vehicle, all factory in­
stalled accessories , a full tank of
fuel, oil, coolant and other fluids
Wheels
plus maximum load. The maxi­
mum load includes the number of
passengers that the vehicle is in­
tended to carry ("seating capaci­
ty") with an assumed weight of
150 lbs (68 kg) for each passen­
ger at a designated seating posi­
tion and the total weight of any
luggage in the vehicle. If you tow
a trailer, the weight of the trailer
hitch and the tongue weight of
the loaded trailer must be includ­ ed as part of the vehicle load .
The
Gross Axle Weight Rating
( " GAWR ") is the maximum load
that can be applied at each of the
vehicle's two axles.
The fact that there is an upper
limit to your vehicle 's Gross Vehi­
cle Weight Rating means that the
total weight of whatever is being
carried in the vehicle (including
the weight of a trailer hitch and
the tongue weight of the loaded
trailer) is limited. The more pas­
sengers in the vehicle or passen­
gers who are heavier than the
standard weights assumed mean
that less weight can be carried as luggage.

are listed on the safety compli­
ance sticker on the driver's side B­ pillar respectively on the front
end of the driver's door.
& WARNING
-
Overloading a vehicle can cause
loss of vehicle control, a crash
or other accident, serious per­
sonal injury, and even death.
-Carrying more weight than your vehicle was designed to carry will prevent the vehicle
from handling properly and increase the risk of the loss of
vehicle control.
-The brakes on a vehicle that
has been overloaded may not
be able to stop the vehicle
within a safe distance .
-Tires on a vehicle that has been overloaded can fail sud ­
denly, including a blowout and
sudden deflation, causing loss of control and a crash .
-Always make sure that the to­ tal load being transported -
including the weight of a trail­
er hitch and the tongue
weight of a loaded trailer -
does not make the vehicle
heavier than the vehicle's
Gross Vehicle Weight Rating.

Determining correct load
limit
Use the example below to calcu­
late the total weight of the pas­
sengers and luggage or other
things that you plan to transport so that you can make sure that
your vehicle will not be overload ­
ed.
Steps for Determining Correct Load Limit
1. Locate the statement "THE
COMBINED WEIGHT OF OCCU­
PANTS AND CARGO SHOULD
NEVER EXCEED XXX KG OR XXX
LBS" on your vehicle's placard
(tire inflation pressure label)
¢ page 344, fig. 277.
2. Determine the combined
weight of the driver and pas­ sengers that will be riding in
your vehicle.
3. Subtract the combined weight
of the driver and passengers
from
"XXX" kilograms or "XXX"
pounds shown on the stick­
er ¢ page 344, fig. 2 77.
4. The resulting figure equals the
available amount of cargo and luggage load capacity . For ex­
ample, if the "XXX" amount
equals 1400 lbs. and there will
.,.

Emergency situations
If you must lift your vehicle with a floor jack to
work underneath , be sure the vehicle is safely
supported on stands intended for this purpose .

Lifting with vehicle jack
Refer to <=:> page 364.
A WARNING
- To reduce the risk of ser io us injury and vehi­
cl e d amage.
- Always lift t he ve hicle only at the special
wo rkshop ho ist and floo r jack lift po ints il­
lustrated <=:>
fig. 300 and <=:> fig. 301.
- Fa ilure to lift the vehicle at these poin ts
could cause the vehicle to til t or fa ll from
a lift if there is a change in vehicle weight
distr ibut io n and balance . This might hap­
pen, for exam ple, when heavy co mpo­
n e nts s uch as the engine b lock or tra ns­
mi ssio n are removed.
- When removing heavy components like
t h ese , a nch or vehicle to hoist o r add cor re ­
s pon ding weigh ts t o ma in ta in t he ce nte r o f
gr avit y. Ot herwise, t he ve hicl e migh t tilt or
s lip
off the hoist, causing ser ious perso na l
injury .
(D Note
- Be awa re o f th e followi ng poi nts before li ft­
in g th e ve hicle:
-The vehicle should never be lifted or
jacked up from underneath the engine oil
pan, the transmiss ion housing, the front
or rear axle or the body side members .
This could lead to serious damage.
- To avoid damage to the underbody or
chassis frame, a rubber pad must be in-
378
serted between the floor jack and the lift
points.
- Before driving over a workshop hoist ,
check that the vehicle weight does not
exceed the permissible lifting capacity of
the hoist.
- Before driving over a workshop hoist , en­
sure that there is sufficient clearance be­
tween the hoist and low parts of the ve­
hicle .
