If an individual wheel begins to rotate too slowly in relation to vehicle
speed and tends to lock, the ABS automatically reduces brake pres­
sure to prevent that wheel from locking .
Thi s automatic adjustment process wi ll cause a
slight vibration of
the brake pedal and some noises to alert you that vehicle speed must
be adapted to existing road and traffic conditions.
_& WARNING
Although the ABS is very effective, always remember that braking
capability is limited by tire traction. Always adjust your driving
speed according to the road and traffic conditions. Do not let the
extra safety afforded by the ABS tempt you into taking extra risks.
The ABS cannot overcome the laws of physics .
(I) Tips
• If ABS is not funct ioning properly, a warning light will come on .
See ~
page 19.
• If a fault occurs in the ABS, the EDL is also not functioning. This is
ind icat ed by the ABS warning light. •
Brake assistant
The brake assistant is designed to achieve the optimum
braking effect.
The brake assistant helps to increase the effective braking power and
thus to achieve a shorter stopping distance.
If the driver presses the
brake peda l very qu ickly , the brake assistant automatically boosts the
braking force to the maximum level, up to the point where the anti­
lock brake function (ABS) intervenes to stop the whee ls from locking.
You should then keep the brake pedal pressed until the vehicle has
braked to the required speed. The brake assistant switches itself off
as soon as you release the brake pedal.
Controls and equip­ ment Safety first Vehicle operation
Automatic full braking
assist
This function allows full braking in spite of high brake pedal forces
(e .g . when the brakes are severely stressed because the veh icle is fully
loaded). The driver notices this function through a reduction of pedal
force and increased pedal travel. When the brake pedal is released,
full braking assist switches off again automatically.
If there is an ABS failure, the brak e assistant and automatic full
braking assist are not available.
Th e brake assistant will not be operative if there is a ma lfunction in
the ABS .
_& WARNING
Please remember that the accident risk always increases if you
drive too fast, especially in corners or on a slippery road, or if you
follow the vehicle ahead of you too closely. Increased risk of an
accident cannot be compensated for even by the brake assistant ,
so always maintain a safe speed.•
Servotronic® -advanced power
steering system
The power steering systems uses the power of the
running engine to allow precise steering with little effort.
The advanced Servotronic ® power steering system senses the road
speed and electronically adjusts power assistance to provide
comfortable and safe steering response exactly matched to the
vehicle speed .
Power steering will not work if the engine is off. As a result , the
steering wheel will be hard to turn .
Th e power steering fluid level is checked during the scheduled main­
tenance services.

Energy management
Starting ability is optimized
E nergy ma nagement co ntr ols the distribution of elec­
trical energy and thus optimizes the availa bility of elec ­
trical energy for s tarting the engine.
If a vehicle with a convention al ene rgy sys tem is not driven fo r a lo ng
pe riod of time, the battery is d ischarged by idling cu rr ent consumers
(e.g. immo bilizer) . In ce rtain c ircumstances it can result i n there
being insufficien t energy avai lab le to start the engine .
Inte llige nt ene rgy management in your ve hicl e han dles the dist ribu ­

and minimize pollution
General
Your personal style of driving will det ermine the economy
of your vehicle, as well as exhaust and noise levels.
Fuel economy, env ironmenta l im pact , and wea r on your e ng ine,
brakes and tires largely depend on t hree factors:
• your person al driv in g style
• operating conditions
• techni cal lim itations

Driving and environment
Drive smoothly and keep a lookout ahead
Vehicles use the most fuel when they are accelerating.
- Avo id unnecessary acce lerating and braking .
Vehicles use the most fuel when they are accelerati ng. If you antici­
pate what is going to happen next, you will need to brake less and,
thus , accelerate less. Let the vehicle coast whenever possible - for
example when you see that the next traffic light is red. •
Avoid full throttle
Driving at moderate speeds saves fuel and improves your
mileage.
- Try and keep well below your car's maximum speed.
Accelerating gently reduces fuel consumption, engine wear, and does
not disturb the environment.
Fuel consumption , exhaust emiss ions and eng ine no ise increase
disproportionately at high speeds. If you drive at approximately three
quarters of top speed, fuel consumption w ill be reduced by one ha lf.
Never drive faster than the posted speed limit and weather condi­
tions pe rm it. •
Reducing unnecessary idling
Even when your car is just idling it burns up fuel.
- Shut the eng ine off when you are not driving the vehicle.
- Do not warm up the vehicle by letting the eng ine run at
idle .
It makes sense to shu t off t he eng ine in traffic jams, when wa it ing for
tra ins to pass at railroad crossings, or at traffic lights that have long waits on red
. Turning the eng ine off for just 30-40 seconds saves
more f uel than is burned start ing the engine aga in.
It takes a long t ime for the engine to warm up fully when it is ru nning
at idle . However, wear and noxious emissions are especia lly high
when the eng ine is wa rming up. So you shou ld drive away as soon as
you start the engine and avoid running at high rpms while the engine
is still warming up .
0 Note
Do not leave engine idling unattended afte r start ing. If warning
lights should come on to indicate improper operation, they would go
unheeded. Extended idling also produces heat, which cou ld result in
overhea ting or other damage to the vehicle or other property. •
Regular maintenance
A badly tuned engine unnecessarily wastes a lot of fuel.
- Have your vehicle serviced at regular intervals.
By having your vehicle regularly serv iced by an authorized Aud i dealer
helps to ensure that it runs properly and economically. The condition
of your vehicle not only affects its safe ty and ability to hold its value,
it a lso affects fuel con sumption .
Che ck your o il e ach time you fill your t ank.
T he amo unt of oil used is related to engine load and speed.
It is normal for the o il consumption of a new engine to reach its
lowest val ue afte r a certa in m ileage has been d riven.
You must drive your veh icle about 3,000 m iles (5,000 kilometers)
before you can properly assess oi l consumption .
T his also app lies to f uel consumption and engine ou tput. ._

service recommendations in your Warranty
& Maintenance booklet .
Lac k of p roper ma inte nan ce as well as imprope r use of the vehicle wi ll
impair the funct ion of the em ission control system and cou ld lead to
damage.
• Do not alter o r remove any component of the Emission Control
System u nless approved by the manufa ct ur er.
• Do not a lter or remove any device, such as heat shie lds, switches,
ign ition w ires , va lves, which are desig ned to protec t your ve hicle's
Emission Contro l System and other important veh icle components .•
Fewer short trips
F uel consumptio n will always be relatively high on short
trips .
-Try to avoi d drivi ng s ho rt dis tances wit h a cold engine .
The engine and catalytic converter have to reach their optima l oper­
ating temperature
t o reduce f uel consum ptio n a nd noxio us em is ­
sions effectively.
Just after starting, a cold engine in a mid -s ize car on ly achieves a fuel
economy of 6-8 m iles per gallon (30- 40 l/l00km) . After about a ha lf
a mile, fuel economy climbs to 12 mpg (20 l/100 km). After abo ut
2 .5 m iles ( 4 km), t he engine i s at its p rop er operat ing temper ature
and fue l economy has reached a normal level. So yo u can see that you
sho uld avoi d short t rips whenever possible.

Driving instructior,s
Driving with a trailer always requires e xtra care and
consideration.
To obtain the best possib le handling of ve hicle a nd trailer ,
please note the following :
- Do not tow a loaded trailer when your car itself is not
loaded.
- Be especia lly careful when pass ing other vehicles .
- Observe speed limi ts.
- Do not drive at the maximum pe rmissible speed.
Controls and equip­
ment Safety first Vehicle operation
- Always apply brakes early.
- Mo
nitor the temperature gauge.
Weight distri but ion
T owing a loaded trailer with an empty car results in a highly unstable
distribution of we ight . If t his cannot be avoided , drive at very low
speeds only to avoid the risk of losing steering control.
A "balanced" rig is easier to operate and control. This means that the
tow veh icle shou ld be loaded to the extent poss ible and permissib le,
wh ile keeping the tra ile r as lig ht as poss ible unde r the ci rc u mstances.
Whe never possible, transfer some cargo to the luggage compart ­
me nt o f the tow vehicle while observing tongue load requirements
and vehicle loading considerations.
Speed
The higher the speed, the more d ifficult it becomes for the driver to
control the r ig . Do not dr ive at the maxim um permiss ible speed .
Reduce your speed eve n more if load, weather or w ind conditions are
unfavorable -particular ly when going downhill.
Reduce vehicle speed
immed iately if the tra ile r shows the slightest
sign of swaying.
Do not tr y to stop the s wayi ng by a ccele rating .
Observe speed lim its. In some areas, speeds for veh icles towing
trailers are lowe r than for regular veh icles .
Always apply brakes early. When driving downhi ll, shift into a lower
gear to use the engine brak ing effect to slow t he ve hicle . Use of the
brakes alone can cause them to overheat and fa il.
Coolant temperatur e
The coo lant temperature gauge=> page 10 must be observed care­
fu lly. If the needle moves close to the upper end of the sca le, reduce
speed immediately and/or turn off the air conditioner.
If the coo lant temperature warning light in the instrument clus ter
starts flash ing
- F- , pull off the road, stop and let the engine idle for
about two m inutes to prevent hea t buil d-up.
