2014 AUDI Q7 coolant temperature

-Antifreeze is poisonous . Always store an­
t ifreeze in its or iginal container and well
out of the reach of children.
- If you drain the coolant, it must be
caught and safely stored in a proper con­
tainer clearly marked "poison".
(D Note
- Coolant pollutes the environment and
could cause an engine fire. Excess coo l­
ant will be forced out through the pres­
sure re lief va lve in the cap when the en­
gine becomes hot.
- If, in an emergency, only water can be
added, the correct ratio between water
and antifreeze ¢
page 264 must be re­
stored as soon as possib le.
@ For the sake of the environment
Drained coolant should not be reused. Al­
ways dispose of used coolant while observ­ ing all environmental regulations .
Radiator fan
The radiator fan switches on automatically by
itself
The radiator fan is driven by the engine via the
V-belt . The viscous clutch regulates the speed
of the fan accord ing to the temperature of the
coolant .
An auxiliary electric radiator fan* switches on
and off depending on coolant temperature
and other vehicle operating conditions .
After you switch the engine off, the auxilia ry
fan can continue running for up to 10 minutes
- even with the ignition off. It can even switch
on again later by itself¢& , if
- the temperature of the engine coolant rises due to the heat build-up from the engine in
the engine compartment, or
- the engine compartment hea ts up because
the vehicle is parked in intense sunlight .
Checking and fillin g 267
A WARNING
-To reduce the risk of personal injury nev­
er touch the rad iator fan.
- The auxiliary electric fan is temperature
controlled and can switch on suddenly
even when the engine is not running .
- The auxiliary radiator fan switches on au­
tomatically when the engine coolant reaches a certain temperature and will
continue to run until the coo lant temper­
ature drops.

Before you check anything in the eng ine com­
partment ,
always read and heed all WARN­
INGS ¢ A in Working in the engine compart­
ment on page 257.
.,. Read the brake fluid level from the brake
fluid reservoir ¢
fig. 246, ¢ page 259,
fig. 241.
The brake fluid level must be be­
tween the "MIN" and "MAX" markings .
The brake fluid reservoir is located at the rear
partition of the eng ine compartment on the
left side ¢
page 259.
The fluid level may drop slightly after some
time due to the automatic adjustment of the
brake pads. This is not cause for alarm. ..,_

274 T ire s and wheel s
-Never mount used tires on yo ur vehicle if
you are not sure of their "previous histo­
ry." Old used tires may have been dam­
aged even though the damage cannot be
seen that can lead to sudden t ire failure
and loss of vehicle control.
- If you notice unusual vibration or if the
vehicle pulls to one side when driving, al­
ways stop as soon as it is safe to do so
and check the wheels and tires for dam­
age.
(D Note
Please note that summer and winter tires
are designed for the cond itions that are
Glossary of tire and loading terminology
Accessory weight
means t he comb ined we ight (in excess of
those sta ndard items which may be rep laced)
of au toma tic tra nsmission, power steer ing,
power brakes, power windows, power seats,
radio, and heater, to the extent that th ese
items are availab le as factory -installed equip­
ment (whether installed or not) .
Aspect ratio
means t he ratio of the he ight to the w idth of
the tire in percent . Numbers of 55 or lower in ­
dicate a low sidewall for improved steering re­
sponse and better overall handling on dry pavement .
Bead
means the part of the ti re that is made of
steel wires, wrapped or reinforced by ply cords
and that is shaped to fit the rim.
Bead separation
means a b reakdown of the bond between
components in the bead.
Cord
means the strands forming the plies in the
tire . typ
ica l in those seasons . Audi recommends
using winter tires during the winter
months . Low temperatures signif icant ly
decrease the e lasticity of summer tires,
which affects tract ion and brak ing ability.
If summer tires are used in very co ld tem­
peratures, cracks ca n form on the tread
bars, res ulting in permanent tire damage
that can cause loud driving no ise and un­
balan ced t ires. Audi is not responsible for
th is type of damage .
Cold tire inflation pressure
means the tire p ressu re recommended by t he
vehicle manufacturer fo r a tire of a des igna ted
s iz e that has not bee n driven for more than a
coup le of miles (k ilometers) at low speeds in
t h e three hour period before the tire pressure
is measured or adjusted.
Curb weight
mea ns the we ight of a motor ve hicl e w ith
standard equipment including the max imum
capacity of fuel, oil, and coolant, air condi ­
tioning and additional weight of optiona l
equipment.
Extra load tire
me ans a t ire design to operate at higher loads
and at h igher inflation pressures than the cor­
responding standard tire . Extra load tires may
be identified as "XL", "x l" , "EXTRA LOAD", or
"RF" on the sidewall.
Gross A xle Weight Rating ("GAWR ")
means the lo ad -c a rry ing c apac ity of a s ingle
axle system , measured a t the tire-ground in­
terfaces.
Gross Vehicle Weight Rating ("GVWR ")
mea ns the maximum total loaded we ight of
t h e ve hicl e. .,.
