Audi drive select (drive
settings)
Introduction
Drive select makes it possib le to exper ience dif ­
ferent types of vehicle sett ings in one veh icle .
T he driver can select
Comfort , Auto and Dynamic
modes in the Infotainment system to sw itch be­
tween, for example, a sporty a nd a comfortab le
driv ing mode .
Yo u can adjust the veh icle sett ings to your per­
so nal preferences in the
Individual mode. This
makes i t possible to combine se ttings such as a
spo rty engine se tt in g with light s teer ing.
Description
T he following systems, among other things, are
influenced by drive se lect:
Engine and transmission
D epend ing on the mode, the engi ne and trans­
mission respon d mo re qu ickl y or in a more bal ­
anced manner to accelerator peda l movements.

111

Ass is tanc e system s
In the sporty dynamic mode, the transmission
shifts at higher speed ranges.
Air su spen sion
The adaptive air suspension/adaptive air suspen­
sion spo rt* is an e lectron ica lly contro lled a ir sus ­
pens ion and damping system . The adjustment
depends on the driving mode selected, steering movements, the driver's braking and accelera­
tion , and as the road surface, vehicle speed and
load . A sporty sett ing is generally used in vehicles
with adap tive a ir suspension sport*.
The vehicle ground clearance depends on the mode se lected and the speed . When you are in
the auto or dynamic mode, the h ighway sett ing is
activated when you dr ive above 75 mph (120 km/
h) for more than 30 seconds . The ground clear­
ance is increased automatically if the speed
drops below 44 mph (70 km/h) for more than 120 seconds .
Stee ring
The power steer ing adap ts . Indirect steer ing that
moves easily as in comfort mode is especially
suited to long drives on a h ighway . The dynam ic
mode p rovides spo rty , d irect steering.
Applies to: vehicles with dynamic steering
The steering ratio changes based on vehicle
speed in order to ma intain optimum steering ef­
fort for the dr ive r at all times . This sets the steer­
i n g to be less sensit ive at hig he r speeds in o rder
to p rovide imp roved vehicle contro l. At reduced
speeds, steer ing is more direct in order to keep
the steering effort as minima l as possib le when
the driv er is maneuvering the v ehicl e. At low and
average speeds, dynamic steering* addit ionally
provides more responsive steering performance.
Sport diff ere ntial *
As a component of the all wheel drive system (quattro)
¢ page 131, the sport differential dis ­
tributes the driving power to the rear axle de ­
pending on the situation. The distribution of
power va ries from balanced (comfort) to sporty
(dynamic) depending on the selec ted mode . The
goal is a high level of agility and ab il ity to accel ­
erate on curves . The ve hicle is very respons ive to
steer ing .
112 Corn
ering light *
The co rnering ligh t adapts the hig h beams to the
direction of the curve depending on the speed.
The pivoting action and the lighting also adapt to
the mode.
Adaptive cruise cont rol*
The be hav io r whe n accelerat ing ca n be adjusted
from comfortable to sporty, depending on the drive select mode. Adaptive cruise control also
responds to the driving behavior of the vehicle
ahead in a more cons ervative or sporty manner.
Engine sound *
The eng ine sound adapts to the c urrent mode
and can be subtle to spo rty.
{[» Note
- Make s ure there is enough clearance above
and be low the vehicle when pa rk ing . T he
heig ht of t he ve hicle can change on ce it is
parked d ue to temperature fluctuations,
changes to the load conditions and changes
to the driv ing modes, which can affect clear­
ance .
- When transporting the vehicle on a car car ­
rier, train, ship or by other means, on ly tie
the vehicle down at the runn ing surface of
the tires, which is the outer c ircumference.
Securing the vehicle at the axle compo­
nents, suspens ion struts o r tow ing eyes is
not pe rm itted because the p ressure i n the

General
This chapter is intended for trained emergency
crews and working personnel who have the nec­
essary tools and equipment to perform these
operations.
Starting by pushing or
towing
~ Note
Vehicles with an automatic transmission can­
not be started by pushing or towing.
Starting with jumper
cables
If necessary, the engine can be started by con­
necting it to the battery of another vehicle .
If the engine should fail to start because of a dis­
charged or weak battery, the battery can be con­
nected to the battery of
another vehicle, using a
pair of jumper cables to start the engine.
Jumper cables
Use only jumper cables of sufficiently large cross
section
to carry the starter current safely. Refer
to the manufacturer's specifications.
Use only jumper cables with
insulated terminal
clamps which are distinctly marked :
plus(+) cable in most cases colored red
minus(-) cable
in most cases colored black.
A WARNING -
Batteries contain electricity, acid, and gas.
Any of these can cause very serious or fatal in­
jury. Follow the instructions below for safe
handling of your vehicle's battery .
-Always shield your eyes and avoid leaning
over the battery whenever possible.
-A dead battery can freeze at temperatures
around 32 °F (0 °C) . If the vehicle battery is
frozen, you must thaw it before connecting
the jump start cables. If you do not, this in-
Emergency situations
creases the risk of an explosion and chemi­
cal burns. After jump starting the vehicle,
drive to an authorized Audi dealer or author­ ized Audi Service Facility immediately to
have the vehicle battery checked.
- Do not allow battery acid to contact eyes or
skin . Flush any contacted area with water
immediately.
- Improper use of a booster battery to start a
vehicle may cause an explosion .
- Vehicle batteries generate explosive gases .
Keep sparks, flame and lighted cigarettes
away from batteries.
- Do not try to jump start any vehicle with a
low acid level in the battery .
- The voltage of the booster battery must also
have a 12-Volt rating . The capacity (Ah) of
the booster battery should not be lower
than that of the discharged battery. Use of
batteries of different voltage or substantial­
ly different "Ah " rating may cause an explo­
sion and personal injury.
- Never charge a frozen battery. Gas trapped
in the ice may cause an explosion.
- Never charge or use a battery that has been
frozen. The battery case may have be weak­
ened.
- Use of batteries of different voltage or sub­
stantially different capacity (Ah) rating may
cause an explosion and injury. The capacity
(Ah) of the booster battery should not be
lower than that of the discharged battery.
- Before you check anything in the engine
compartment, always read and heed all
WARNINGS
c>page 272.
@ Note
- Applying a higher voltage booster battery
will cause expensive damage to sensitive
electronic components, such as control
units, relays, radio, etc.
- There must be no electrical contact between
the vehicles as otherwise current could al­
ready start to flow as soon as the positive
( + ) terminals are connected.
327

Emergency situations
@ Tips
The discharged battery must be properly con­
nected to the vehicle's electrical system .
When jump starting or charging the battery,
never connect the negative ground cable to
the battery negative post because the battery
manager system must be able to detect the
battery's state of charge. Always connect the
negat ive g round cable to the negative ground
post of the battery manager control unit.
Using the jump start
cable
Both jump start cables must be connected in the
correct order!

The procedure for connecting jump start cables
that is descr ibed next is designed to help jump
start your vehicle.
Vehicle with discharged battery:
~ Turn off lights and accessories, move automatic
transmission lever to N (Neutral) or P (Park)
and set parking bra ke.

Connecting the positive cable (red) to the
positive terminal
~ Open the cover on the positive terminal
qfig . 289.
1. Secure one end of the pos itive cable (red) to
the jump start pin
(D q fig. 290 (pin under
the cover =
"plus") on the vehicle that needs
to be started @.
2. Secure the other end of the positive cable
(red) to the posit ive terminal @on the bat­
tery provid ing the cur rent @.
Connecting the negative cable (black) to the
negative terminal
3. Secure one end of the negative cable (black)
to the negative terminal @ on the battery
that is providing the current @.
4. Secure the other end of the negative cable
(black) to the jump start
pin @ (hex head pin
= "negative") on the vehicle that needs to be
started @.
Starting the engine
~ Sta rt the eng ine on the vehicle providing the
jump start @and let it run at idle.
~ Now start the engine on the vehicle with the
drained battery @.
~ If the engine does not start, stop the starting
procedure after 10 seconds and then repeat it
after approx imately 30 seconds.
~ Remove the cables when the engi nes are run­
ning. Remove them in reverse order from the
way they were installed.
~ Close the cover on the posi tive terminal.
The battery is vented to the outside to prevent
gases from enter ing the vehicle interior. Make
sure that the jumper clamps are well connected
with their
metal ports in full contact with the
battery terminals .
A WARNING
-To avoid serious personal injury and damage
to the vehicle, heed all warnings and instruc­
tions of the jumper cable manufacturer. If in
doubt, call for road service.
-Jumper cables must be long enough so that
the vehicles do not touch.
