vehicle doors and windows are closed before leaving the vehicle. •

Clear vision
in. WARNING
Wiper blades are crucial for safe driving! Only in good condition are they able to clear the windows properly to provide unrestricted
visibility. Worn or frayed wiper blades are a safety hazard!
=> page 69, "Replacing front wiper blades"
(D Note
In freezing or near freezing conditions:
• Always check that the wiper blades are not frozen to the glass
before you turn the wiper on. Loosen a wiper blade which is frozen in
place before operating the wiper to prevent damage to the wiper
blade or the wiper motor.
• Do not use the wiper to clear a frosted window . Using the wipers
as a convenient ice scraper will destroy the wiper blades.
[I) Tips
For better rearward vision when parking, the rear window wiper is
automatically activated one time when the windshield wipers are
switched on and reverse gear is engaged. •
Service position
Replacing the windshield wiper blades is only possible when
you move the wiper arms into the service position. In order to
use the windshield wipers, the hood must be completely
closed. When there is a risk of frost, make sure that the wiper
blades are not frozen to the windshield.
- Switch the ignition on. - Switch the
ignition off again and move the wiper lever
=:> page 65, fig. 62 from position Oto 1 within
10 seconds. The wiper arms now move into the field of
view in the windshield.
The service position can also be selected in the driver information
system*=>
page 22 .
(D Note
Never drive your vehicle when the windshield wiper arms are in the
service position and pulled away from the windshield. When you drive
faster than 4 mph (6 km/h) , the wiper arms automatically return
back to the park position and could cause paint damage to the engine
hood!
[I) Tips
• You can also turn on the service position, for example, if you want
to protect the windshield from icing by using a cover.
• The service position moves to
off automatically when you operate
the windshield wiper lever, or speed exceeds 4 mph (6 km/h). •

Braking
General Information
What af fect s braki ng effici ency ?
Operating condit ions and driv ing habits
Th e br akes on today's autom obil es are s till subjec t to we ar,
depend ing large ly on operating conditions and driving habits=>& .
O n veh icles t hat are ei ther driven mos tly in sto p-an d-go ci ty traff ic or
are driven ha rd, the bra ke pads s hould be checked by your author ized
Aud i dealer mo re o ften t han specif ied in the
Warranty & Mainte­
nance booklet .
Failure to have your brake pads ins pected can resu lt
in re duced brake pe rformance.
O n steep slopes, you shou ld use the brak ing effect of th e engine . This
way, yo u prevent unnecessary wea r on the brake system. If yo u must
u se your b ra kes, do n ot ho ld the bra kes down conti nuou sly. P u m p the
brakes at intervals .
N oises may occur when brakin g dependin g on s peed, braki ng fo rce
and outs ide cond itions s uch as temperatu re and hum id ity.
Moisture or road salt
If you are driving fas ter than 50 mp h (8 0 km/h) and th e w indshield
w ipers are on , the b ra ke pads w ill briefly touch t he br ake discs in
reg ula r intervals so as to improve react io n ti me when brak ing on wet
s u rfaces. Yo u, the drive r, will not not ice anything .
Under cert ain con ditions , for ex am ple , w hen driving throug h w ater or
very heavy rain, or even after was hing your veh icle, the bra king effect
c an be redu ced due to moi sture (or in fr eezin g condi tion s ice) on the
brake pads . A few cautious brake app lications sho uld dry off the
bra ke p ads or remove any ice coa ting s.
Controls and equip­
ment Safety first Vehicle operation
T
he effect iveness of the brakes can be reduced when the vehicle is
dr ive n o n a salt-c overe d road and t he brakes are not us ed. Likew ise,
you clea n off acc umulated salt coat ing from brake d iscs and pads
w ith a few cautio us app lications of the brake=>& .
Corrosion
There ma y be a te nd ency fo r dirt to b uild up o n the brak e pa ds and
co rrosion to form on the discs if the car is not dr iven regu la rly o r only
for short trip s wit h litt le u se of the bra kes.
If th e bra kes are not used freq uent ly, or if co rrosion has formed o n
th e discs, it is advisable to clean off the pads an d discs by brak ing
fi rmly a few times fro m a mode ra tely high speed =>& .
Faults in the brake system
If yo u should no tice a sudden increas e in brake pedal t ravel, then one
o f the two brake ci rcu its may have failed =>& .
Low brake fluid level
Malf u nctions can occu r in t he brake sys tem if the brake fluid level is
t oo low . T he bra ke fluid level is mo nitored e lectro nica lly .
Brake lining wear status
Brake lining wear may be checked by v isua l inspect ion of the condi­
t ion of the bra ke pa ds through the o penings in the wheel. If neces ­
sary , the whee l may be removed for th is inspect ion=>
page 27 2,
"Wheel c hange" .
& WARNING
• You should perform braking maneuvers for the purpose of
cleaning the brake system only if road conditions permit . Other
road users must not be put at risk -you may cause an accident!
• Before descending a steep grade, reduce speed and shift trans­
mission into a lower gear or lower driving range. Do not ride the
brakes or hold the pedal down too long or too often. This could
cause the brakes to get hot and diminish braking efficiency.

e xtra safety afforded by th e ABS tempt you into taking extra risk s.
The ABS cannot overcome the laws of physics .
[ i J Tips
• If ABS is not funct ioning properly, a warning light will come on .
See ~
page 16 .
• If a fault occurs in the ABS, the EDL is also not functioning. This is
ind ic at ed by t he A BS w arni ng light. •
Brake assistant
The broke assistant is designed to achieve the optimum
br oking effect.
Th e b rake ass istant he lps to inc rease t he effective brak ing powe r and
thus to ac hieve a shorter stopping distance.
If the driver presses the
bra ke ped al ve ry qu ickly, the b rake assistant au toma tically bo osts the
brak ing force to the max imum level, up to the point where the anti­
lo ck brak e function (ABS) in tervenes to stop the whee ls from l ocking.
You should then keep the brake pedal pressed unti l the vehicle has
bra ke d to t he require d spee d. T he bra ke ass istan t swi tches itse lf off
as soon as you re lease the b rake pedal.
Th e brake assistant will not be operative if there is a ma lfu nctio n in
t he A BS .
& 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 th e vehicle ahead of you too closely. An increased accident
risk cannot be compensated even by the brake assistant, so always
maintain a safe speed .•

Driving and environment
New brake pads have to be "burnished in" before they have optimal
grab ~& .
Dur ing the break-in period, you should avoid putting severe loads on
the bra kes. Severe loads incl ude, for example, sudden hard braking,
in part icu lar at very high speeds or, for examp le, on mountain passes .
& WARNING
Until they develop th e ma ximum "bite " for b est stopp ing pow er,
the surfaces on new brake pads require some "breaking-in" during
the in itial 100 to 150 mile s (150 to 200 kilometers ) of normal
city dr iving. You can compensate for this by p ress ing the brake
pedal more firml y. Thi s applies whenever n ew pads are in stalled .•
Driving through water on roads
---
N ote the following to avoid vehicle damage when driving through
water, fo r example on flooded roads:
• Th e wate r mus t not be any higher th an the bottom of the ve hicl e
body.
• Do not dr ive faster t han wal king speed.
& WARNING
After driving through water, mud , slush, etc ., th e brak es may be
slow to take effect because of wet brake rotors and pads . Dry the
brakes first by braking carefully to restore the full braking effect .
0 Note
Vehicle components such as the engine, transmission, suspension or
electrical system can be severely damaged by driving thro ugh water.
W Tips
• Check t he dept h of the wa ter before dr iv in g thro ugh it.
• Do not stop the vehicle, drive in reverse or sw itch the engine off
when driving through wate r.
• Keep in m ind t hat on coming vehicles may cre ate w aves t hat raise
the water level and make it too deep for your vehicle to drive thro ugh
safe ly.
• Avoid dr iv in g through sa lt water because it can cause corros ion. •
Catalytic converter
It is very important that y our emiss ion con trol system
(ca talyti c converte r) is func tioning pr operly to ensure
that your vehicle is running i n an environm entally sou nd
manner.
- Always use lead-fre e gasoline => page 219, "Fu el supply".
- Never run the ta nk down a ll the way to empty .
- Never p ut too much mo tor o il in your engine=>
pag e 232,
"Adding engine oil~" -
- Neve r try to pu sh- or tow-start you r vehicle.
T he catalytic converter is an efficient "clean- up" device b uilt into the
exhaust system of the veh icle. The cata lytic converter b urns many of
t he poll uta nts in the e xhaust g as before they are released in to the
atmosphe re.
Th e ex clusive use o f unleaded fuel is c ritic ally impor tant for the life of
the cata lytic converte r and proper f unction ing of the engi ne. ..,
