Notice about data
recorded by vehicle
control modules
Your veh icle is not equipped with an Event Da­
ta Recorde r (EDR), installed by some manu­
facturers fo r the express p urpose of capturing
data for retrieval after an accident or crash
event . EDR's are sometimes ca lled "crash re­
corders".
Some state laws restr ict the retr ieval or down­
loading of data stored by EDR's that were in­
stalled in a vehicle for the express purpose of retrieving data after an accident or crash
event without the owner's consent.
A lthough your vehicle is not equipped with an
EDR, it is equipped with a number of electron­
ic control modules for various vehicle systems
such as, for examp le, eng ine function, em is­
sion control, as well as for the airbags and
safety belts.
These electronic contro l modules also record
vehicle-re lated data during norma l vehicle op­
erat ion for diagnostic and repa ir purposes.
The recording capacity of the electronic con­
trol modules is limited to data (no sound is re­
corded) and only a small amount of data is ac­
tually recorded over a ve ry limited pe riod of
time and stored when a system fault or other
cond ition is sensed by a cont ro l unit. Some of
the data then stored may re late to vehicle
speed, direction, braking as we ll as restraint
system use and performance in the event of a
crash or other condit ion. Stored data can only
be read and downloaded with special equip­
ment.
Electronic Stabilization
Control (ESC)
Description
ESC helps to improve road holding and vehicle
dynamics to help reduce the probability of
skidd ing and loss of vehicle control. It works
only when the eng ine is running. ESC detects certain difficult driving situat
ions, including
when the vehicle is beginning to spin (yaw)
out of control and he lps you to get the veh icle
back under control by se lectively braking the
wheels, and/or reducing eng ine power and
providing steer ing ass istance to he lp hold the
vehicle on the dr iver's intended course. The in­
dicator light
G) in the inst rument cluster
blinks when ESC is ta king action to help you
control the veh icle.
ESC has limitations.
It is importa nt to remem­
ber that ESC cannot overcome the laws of
physics. It wi ll not always be able to help out
under a ll cond it ions you may come up aga inst.
For example, ESC may not always be able to
help you master situations where there is a
s u dden change in the coefficient of friction of
the road surface. When there is a section of
dry road that is sudden ly covered w ith water,
slush or snow, ESC cannot perform the same
way it wou ld on the dry surface . If the ve hicle
hydroplanes (rides on a cushion of water in­
stead of the road surface), ESC will not be
able to help you steer the vehicle because con­
tact with the pavement has been in terrupted
and the vehicle cannot be braked or steered .
D uring fast cornering, particularly on winding
roads, ESC cannot always deal as effectively
with difficult driving situations than at lower
speeds. When towing a trailer, ESC is not able
to help you regain control as it would if you
were not tow ing a trailer.
Always adjust your speed and driving style to road, traffic and weather condit ions. ESC can­
not override the vehicle's physical limits, in­
crease the available tract ion, or keep a ve hicle
on the road if road departure is a result of
drive r inattent ion. Instead, ESC imp roves the
poss ibil ity of keeping the vehicle under con ­
trol and on the road during ex treme maneu­
vers by using the d river's steering inputs to
help keep the vehicle going in the intended di­
rection . If you are traveling at a speed that
ca uses you to run off the road before ESC can
provide any assistance, you may not experi­
ence the benefits of ESC.

Tire service life
The service life of tires depends on a lot of
different things including proper installation
and balan cing, correct tire pressure and driv­
ing style.

ing on the ma ke, there will be six to eight of

the tire sidewall (for example "TWI" or other
symbols) ind icate the positions of the tread

Tire pressure
Incorrect t ire pressure causes premature wea r
and can cause sudde n tire blow-out . For this
reason, tire pressu re must be checked at least
o nce a month
¢ page 246 .
Driving style
Driving fast around c urves , heavy accelerat ion
and hard braking increase tire wear .
Rotating tires for more even wear
F or all four tires on your ve hicle to have the
same service life, we recomme nd that the
front and rear tires are rotated accord ing to
the tire manufact urer's suggested tire rota­
tion intervals. Please remembe r th e follow­
i ng:
- T ire rotation intervals may differ from the
veh icle service intervals o utli ned in your
Warranty
& M ain tena nce booklet.
- The longer one tire is used in one location
on t he vehicle, the more it wears at certain
points; the refore , we recommend that you
follow the tire man ufac turer's suggested
tir e rotat ion intervals.
- Ve hicles w ith front -wheel dr ive experience
more trea d wear on the fro nt wheels com­
pa red to all-wheel d rive (q uattro).
- Please rotate tires as shown ¢

Emergency situations
General
This chapter is intended for trained emer­
gency crews and working personnel who
have the necessary tools and equipment to
perform these ope rations.
Starting by pushing or
towing
Q;) Note
Vehicles w ith an automatic transmission
cannot be started by pus hing o r tow ing.
Starting with jumper
cables
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 veh icle,
using a
pair of jumpe r cables to start the en­
g ine .
Jumper cables
Use only jumper cables of sufficiently large
cross section to carry the starter current safe­
ly. Refer to the manufacturer's specif ications.
Use only jumper cables with
insulated termi­
na l clamps which are distinctly marked:
plus(+) cable in most cases colored red
minu s(-) cable
in most cases colored black .
A WARNING
Batteries contain electricity, acid, and gas.
Any of these can cause very serious or fatal
inju ry. Follow the instructions below for
safe handling of your veh icle's battery.
- Always shield you r eyes and avoid lean­
ing over the battery whenever possible.
- A discharged battery can freeze at tem­
peratures just be low 32 °F (0 °C). Before connecting a
jumper cable, you must
thaw the frozen battery complete ly, oth­
erwise it could explode.
- 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 gas­
es. Keep sparks, flame and lighted ciga­
rettes away from batteries.
- Do not try to jump start any vehicle with a low acid level in the battery.
- The vo ltage 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 bat­
tery . Use of batteries of d ifferent voltage
or substantially different "Ah" rating
may cause an exp losion and personal in­
jury.
- Never charge a frozen batte ry. Gas trap­
ped in the ice may cause an explosion.
- Never charge or use a battery that has
been frozen. The battery case may have
be weakened.
- Use of batter ies of different voltage or
substantially different capacity (Ah) rat­
ing may cause an exp losion and injury.
The capacity (Ah) of the booster battery
should not be lower than that of the dis ­
charged battery.
- Before you check anything in the engine
compartment, always read and heed a ll
WARNINGS¢
page 224.
(D Note
- App lying a higher voltage booster bat­
tery will cause expensive damage to sen­
sitive electronic components, such as
contro l units, relays, radio, etc .
- Th ere must be no electrical contact be­
tween the vehicles as otherwise current cou ld already start to f low as soon as the
positive(+) terminals are connected. .,.
