2014 AUDI R8 SPYDER wheel torque

78 Transmission
@ Tips
-When accelerating using the Launch
Control program, all vehicle parts are
subject to heavy loads. This can result in
increased wear.
- The Launch Control Program only func­
tions when the parking brake is released
and the vehicle speed is less than
3 mph
(5 km/h).
S tronic®
Description
Applies to vehicles: with S tronic
Fig. 83 Shift pattern
Fig. 84 Display: selected gears
Your vehicle is equipped with an electronical­
ly-controlled manual transmission called S
tronic ®. Two independent clutches transfer
the powe r between the engine and transmis­
sion. They replace the torque converter used
in conventional automatic transmissions and
allow the vehicle to accelerate without a no­
ticeable interruption in traction.
The selected mode of operation, the gear en­
gaged and the sport function are shown in the
Driver Information System display ¢
fig. 84.
M -Manual operation
In this operating mode, you shift the forward
gears using the selector lever ¢
page 79 or
the shift paddles on the multifunction steer­
ing wheel¢
page 81.
A - Automatic operation
In this opera ting mode, the forward gears are
shifted up or down depending on engine load
and vehicle speed ¢
page 80.
R- Reverse
Only shift into reverse gear when the vehicle is
stationary and the engine is running at idle
speed~ ,&..
To engage reverse gear, you have to press the
brake pedal, move the selector lever to the
right and tip it towards R . In reverse gear, the
backup lights illuminate when the ignit ion is
on .
N -Neutral
To engage neutral, you have to move these­
lector lever to the left or to the right.
If re­
verse gear is engaged, move the selector lever
to the left.
If a forward gear is engaged, move
the selector lever to the right.
Sport function
The sport function is sw itched on by pressing
the
I SPOR T I button on the selector lever cover.
Upshifting at a higher RPM makes full use of
the engine's power. Shift time is decreased
and acce le rator pedal response is improved.
In addition, in manual operation the engine
does
not shift automatically into the next
gear before it has reached the maximum per­
missible engine speed. In automatic opera­
tion, upshifting continues automatically.
P - Automatic parking lock
The automatic parking lock is engaged imme­
diately after you remove the key. The auto­
matic parking lock is also engaged if you turn
off the engine while in the A, R, or manual
mode positions. .,..

A WARNING ,~
Using the wrong snow chains for your vehi­
cle or installing them incorrectly can in ­
crease the risk of loss of control leading to
serious personal injury.
- Snow chains are available in different sizes. Always make sure to follow the in­structions provided by the snow chain
manufacturer .
- When driving with snow chains, never
drive faster than the speed permitted for
your specific snow chains.
- Always observe local regulations .
(D Note
-Remove snow chains before driving on
roads not covered with snow to avoid
damaging tires and wearing the snow
chains down unnecessarily.
- Snow chains, which come into direct con­
tact with the wheel rim, can scratch or
damage it . Therefore, make sure that the
snow chains are suitably covered. Check
the position of the snow chains after
driving a few yards and correct if neces­
sary. Follow the instructions from the
snow chain manufacturer when doing so.
@ Tips
Where snow chains are mandatory oncer­
tain roads, this normally also applies to
vehicles with all-wheel drive.
Wheel bolts
Wheel bolts must always be tightened to the
correct torque.
The design of wheel bolts is matched to the
factory installed rims. If different rims are fit­
ted, the correct wheel bolts with the right length and correctly shaped bolt heads must
be used. This ensures that wheels are fitted
securely and that the brake system functions
correctly .
Tires and wheels 205
In certain circumstances, you may not use
wheel bolts from a different vehicle -even if it
is the same model
r:!> page 229.
A WARNING
Improperly tightened or maintained wheel
bolts can become loose causing loss of
control, a collision and serious personal in­
jury.
- Always keep the wheel bolts and the
threads in the wheel hubs clean so the
wheel bolts can turn easily and be prop­ erly tightened.
- Never grease or oil the wheel bolts and
the threads in the wheel hubs . They can
become loose while driving if greased or
oiled, even if tightened to the specified
torque.
- Only use wheel bolts that belong to the
rim being installed.
- Never use different wheels bolts on your
vehicle.
-Always maintain the correct tightening
torque for the wheel bolts to reduce the
risk of a wheel loss. If the tightening tor­
que of the wheel bolts is too low, they
can loosen and come out when the vehi­
cle is moving. If the tightening torque is
too high, the wheel bolts and threads can be damaged and the wheel can be­
come loose.
(D Note
The specified torque for the wheel bolts is
90 ft lb (120 Nm) with a tolerance of ± 7 .4
ft lb(± 10 Nm). Torque wheel bolts diago­
nally. After changing a wheel, the torque
must be checked as soon as possible with a
torque wrench -preferably by an author­
ized Audi dealer or qualified workshop.
Low aspect ratio tires
Your Audi is factory-equipped with low aspect
ratio tires. These tires have been thoroughly
tested and been selected specifically for your model for their superb performance, road feel .,.

216 What do I do now?
Removing the wheel
.. Use the hexagonal socket in the screwdriv­
er handle
to comp letely turn out the top­
most wheel bolt and set it aside on a
clean
sur face .
.. Screw the threaded end of the
alignment
pin
from the tool kit hand-tight into the
now vacant bolt hole
o fig. 162.
.. Then completely unscrew the other wheel
bolts as described above .
.. Take off the wheel leav ing the alignment pin
in the bolt hole
o(D .
Putting on the wheel
.. Lift the spare wheel and carefully slide it
over the alignment pin to guide it in place
o@.
.. Use the hexagonal socket in the screwdr iver
handle to screw in and tighten all wheel
bolts
slightly .
.. Unscrew the alignment pin and insert and
tighten the remaining whee l bolt slig htly
like the rest.
.. Turn the jack handle counter-clockw ise to
lower the vehicle until the jack is fully re­
leased .
The wheel bolts must be clean and turn easily.
Check the contact surfaces of wheel and hub. Remove contaminants on these surfaces be­
fore installing the wheel.
The hexagonal socket in the screwdriver han ­
dle makes it easier to handle the wheel bolts.
The reversible blade should be removed.
When mounting
unidirectional tires, observe
the direction of rotation
o page 214.
«I) Note
When removing or installing the wheel,
the rim could hit the brake rotor/ceramic
brake rotor* and damage the rotor. Work
carefully an have a second perso n he lp

Tightening wheel bolts
.. Fit the wheel bolt wrench over the wheel
bolt and push it down as far as it will go
ll.
.. Close your grip around the end of the
w rench handle for maximum torque and
turn each wheel bolt
clockwise until it sits
tight .
Have the
tightening torque of the wheel bolts
checked as soon as possible with a to rque
wrench. It should be 120 Nm .
Check the
tire pressure as soon as possible.

What do I do now? 217
Jump-starting
General
If necessary, the engine can be started by
connecting it to the battery of another vehi ­
cle.
If the engine should fail to start because of a
discharged or weak battery, the battery can be
connected to the battery of
another vehicle,
us ing a
pair of jump er cabl es to start the en­
gine.
Both batteries must be rated at 12 volts . The
capacity (Ah) of the booster battery must not
be substantia lly less than the capac ity of the
discharged battery .
Jumper cables
Use only jumper cables of suff ic ient ly large
cro ss se ction to safely car ry the starter cur ­
rent . Refer to the manufacturer's specifica­
tions .
Use only jumper cab les which have
insulated
term inal clamps and are properly marked for
dist inction:
plu s(+) cable : in most cases colored r ed
