coolant capacity AUDI A8 2018 Owners Manual

Cockpit overv iew
CD Note
- Auxiliary headlights and other accessories in
front of the cooling-air intake impair the
cooling effect of the coolant. This increases
the r isk of the engine overheat ing during
high outside temperatures and heavy en-
gine load.
- The front spoiler also helps to distr ibute
cooling air correctly wh ile driving. If the
spoiler is damaged, the cooling effect will
be impaired and the risk of the engine over­
heating will inc rease. See an a uthorized
A ud i dealer or authorized Audi Service Fa­
cility for assistance .
Tachometer
The tachometer displays the engine speed in rev ­
olutions per minute
(RPM).
You should shift to the next lowest gea r when
the speed is below 1,500 RP M. The beginn ing of
the red zone in the tachometer ind icates the
maximum permissible engine speed fo r all gears
once the engine has been broken in and when it is
warmed up to operating temperature . Before
reaching this zone, you should shift into the next
highest gear, select the D selector lever position,
or remove your foot from the accelerator pedal.
~ Note
The needle in the tachometer @ c:> page 9,
fig. 3 may only be in the red area of the gauge
for a short time or there is a risk of engine damage. The locat ion where the red zone be­
gi ns varies depending on the engine.
@ For the sake of the environment
Upshifting early helps you to save fuel and re­
duces operating noise.
Fuel level
The display @ only works when the ignition is
sw itched on. If the fuel level drops below 4 gal
(15
L), a red L ED will light up and the Ill indica­
tor light will turn on
c:> page 24. The red LED
will blink when the fuel level is very low.
10
The fuel tank capacity of your ve hicle is listed in
the
Techn ical Data section c:> page 334.
CD Note
Neve r drive until the tank is comp letely emp­
ty. The irregu lar supply of fuel th at results
from that can cause engine misfires . Uncom­
busted fuel w ill then enter the exhaust sys­
tem. This can cause overheating and damage
to the catalyt ic converter.
Odometer
Fig. 4 Instru ment cluster: odometer and reset button
Upper odometer
The trip odometer shows the distance driven
s ince it was last reset.
It can be used to measure
short distances.
The trip odometer can be reset to zero by press ­
ing
the ~ reset button.
Lower odometer
The lower odomete r shows the total distance
that the vehicle has driven.
Malfunction indicator
If there is a malfunction in the instrument clus­
ter,
DEF will appear in the trip odometer display.
Have the malfunction corrected as soon as possi­
ble.

Wheels

reinforced by ply cords and that is
shaped to fit the rim .
Bead separation
means a breakdown of the bond
between components in the bead .
Cord
means the strands forming the
plies in the tire .
Cold tire inflation pressure
means the tire pressure recom­
mended by the vehicle manufac­
turer for
a tire of a designated
size that has not been driven for more than a couple of miles (kilo­
meters) at low speeds in the
three hour period before the tire pressure is measured or adjusted .
Curb weight
means the weight of a motor ve­
hicle with standa rd equipment in ­
cluding the maximum ca pacity of
fuel, oil, and coolant, air condi ­
tioning and addit ional weigh t of
optional equipment.

spond ing standard tire. Extra load
tires may be identified as "X L",
"xl" , "EXTRA LOAD" , or "RF" on
the sidewall.
Gross Axle Weight Rating ("GAWR")
means the load-car rying capacity
of a single axle system , measu red
at the ti re-ground interfaces .
Gross Vehicle Weight Rating
("GVWR")
means the maximum total loaded
weight of the vehicle .
Groove
means the space between two ad­
jacent tread ribs .
Load rating (code)
means the maximum load tha t a
tire is rated to carry for a given i n­
flation pressure. You may no t find
this informat ion on all ti res be­
cause it is not required by law .
Maximum load rating
means the load rating for a tire at
the maximum permissible infla­
tion pressure for that tire .
Maximum loaded vehicle
weight
means t he sum of:

Weights
Gross Vehicle Weight Rating
The Gross Vehicle Weight Rating (GVWR), and
the Gross Axle Weight Rating (GAWR) for front
and rear are listed on a sticker on the door jamb
on the driver's side .
The Gross Vehicle Weight Rating includes the
weight of the basic vehicle p lus full fuel tank, oi l
and coolant, plus maximum load, which includes
passenger weight (150 lbs/68 kg per designated
seating position) and luggage
we ight¢ &..
Gross Axle Weight Rating
The Gross Ax le Weight Rating is the maximum
load that can be applied at each axle of the vehi ­
cle
¢ &. .
Vehicle capacity weight
The vehicle capacity weight (max. load) is listed
either on the driver's side B-pillar or inside the
fue l filler f lap .
A WARNING
- The actual Gross Axle Weight Rating at the front and rear axles should not exceed the permissible weights, and their comb inat ion
must not exceed the Gross Veh icle Weight
Rating .

Approximate capaci-
ties
2 1. 7 gal (82.0
L)
5.3 qt (5.0 L)
- Exceed ing permissible weight ratings can
result in vehicle damage, accidents and per­
sonal injury.
@ Note
- The veh icle capacity weight figures apply
when the load is d istr ibuted evenly in the
vehicle (passengers and luggage) . When
transport ing a heavy load in the luggage
compartment, carry the load as near to the
rea r axle as possible so that the vehicle's
hand ling is not impai red.
- Do not exceed the maximum permissible
ax le loads or the maxim um gross vehicle
we ight . A lways remember that t he ve hicle's
handling will be affected by the extra load.
Th erefore, adjust your speed accordingly .
- Always observe local regulations .
