General information
Breaking in
A new vehicle must be broken in, and the break­ in distance should be 1,000 miles (1,500 km).
For the first 600 miles (1,000 km), do not drive
at speeds that are more than 2/3 of the maxi­
mum permitted RPM, avoid full acceleration and
do not tow a trailer. You may gradually start in­
creasing the RPM and the speed between 600 miles (1,000 km) and 1,000 miles (1,500 km) .
During the first hours of use, the engine has a
higher internal friction than later on when all
moving parts have settled into place with each
other.
How the vehicle is driven during the first 1,000
miles (1,500 km) also affects the engine quality.
Drive at moderate engine speeds after the initial
break-in period, particularly when running a cold
engine . This will reduce engine wear and improve
the mileage .
Do not drive at too
low of an engine speed (rpm).
Shift down if the engine stops running "smooth­ ly". Extremely high engine speeds are automati­
cally reduced .
Avoid damaging the vehicle
When you are driving on poor roads, or over
curbs, steep ramps , etc., make certain that low­
lying parts such as spoilers and exhaust system
parts do not bottom out and get damaged.
This is especially true for vehicles with low-slung
chassis (sports chassis)* and fully loaded
vehicles.
Driving through water on roads
Note the following to reduce the risk of vehicle
damage when driving through water, for example
on flooded roads:
- The water must not be any higher than the bot­
tom of the vehicle body.
- Do not drive faster than walking speed.

A WARNING ,_
After driving through water or mud, the effec­
tiveness of the brakes may be reduced due to
moisture on the brake rotors and brake pads.
A few careful brake applications should dry
off the brakes.
([) Note
Vehicle components such as the engine,
transmission, suspension or electrical system
can be severely damaged by driving through
water.
(D Tips
- Determine the depth before driving through
water.
- Do not stop the vehicle, drive in reverse or
switch the engine off when driving through
water.
- Keep in mind that oncoming vehicles may
create waves that raise the water level and
make it too deep for your vehicle to drive
through safely.
-Avoid driving through salt water, because
this can cause corrosion.
Economical and environmentally-friendly
driving
The amount of fuel consumption, the environ­
mental impact and the wear to the engine,
brakes and tires depends mostly on your driving
style . With an anticipatory and economic driving
style, fuel consumption can be reduced by ap­ proximately 10-15%. The following tips will help
you conserve the environment and your money at
the same time.
Anticipatory driving
A vehicle uses the most fuel when accelerating .
When you drive with anticipation, you do not need to brake as often and so you accelerate less.
When possible , let your vehicle coast with a gear
engaged, for example, when you notice that the
next traffic light is red. This produces an engine
braking effect, which helps to protect the brakes
and tires and reduces the emissions and fuel

compensate for the slightly reduced bra king
force by pressing firmly on the brake peda l. Avoid
heavy braking during the break -in period .
Operating condit ion s and dr iving habits
The brakes on today's automobiles a re sti ll s ub­
ject to wear, depend ing largely on ope rating con­
ditions and driving habits¢& . On vehicles that
are either driven most ly in stop-and -go city traf ­
fic or are driven hard, the brake pads should be
checked by your authorized Aud i dealer more of­
ten than specified in the
Warran ty & Mainte ­
n anc e boo kle t .
Failure to have your brake pads
inspected can resu lt in reduced brake perform­
ance.
On steep slopes, you should use the braking ef­
fect of the eng ine. This way, you prevent unnec­
essary wear on the brake system . If you must use
your brakes, do not hold the b rakes down cont in­
uously. P ump t he b rakes at intervals.
Operating no ise
Noises may occur when braking depend ing on the
speed, braking force and outs ide cond itions such
as tempe rature and humidity .
Effect of water or road salt
In certain situations, for example after driving
through water, in heavy ra in, after overnight con­
densat ion or after washing your car, the braking
effect can be reduced by mo isture or ice on the
brake rotors and brake pads . The brakes must be
"dr ied" fi rst w it h a few careful brake applica­
tions .
At highe r speeds and with the windsh ield w ipers
turned on, the brake pads press aga inst the brake
rotors for a short amount of time. This action,
which is not felt by the d river, happens a t regular
i nte rvals and ens ures a better reaction time fo r
the brakes in wet weather.
The bra king effect can also be redu ced if you are
d riving on salted roads and you do not apply t he
b ra kes fo r long pe riods of time. The layer of sa lt
on the brake rotors and brake pads m ust be worn
off first when the b rakes are applied¢& .
Intellig ent Technology
Corrosion
Leaving t he vehicle pa rked fo r lo ng periods of
t ime, low mileage and avoiding heavy braking
can contrib ute to corrosion on the brake rotors
and to dirty brake pads .
If you usua lly avoid heavy bra king or if there is
corrosion present, occasiona l heavy braking at
high speeds is recommended to clean the brake
rotors and pads¢& .
Brake system malfunction
if you no tice that the b rake peda l t ravel has sud ­
denly
gotten larger, then a b rake c ircuit may have
f ailed ¢ & .
Low brake fluid level
When the brake fluid level is low, malfu nctions in
the b rake system may occur. The b rake fl uid level
is e lec tron ically moni tored.
Brake booster
The brake booster amplifies the pressure you ap­
ply to the brake pedal.
It only works when the en­
gine is running~ &.
Brake lining wear statu s
Brake lining wear may be checked by visual in­
spect ion of the condition of the brake pads
t h rough the openings in the wheel. If necessary,
the wheel may be removed for this i nspection
¢ page 198, Replacing wheels .
,&. WARNING
-New brake pads don't have the bes t stop­
ping power and m ust be "broken-in" during
the initial 250 mi (400 km) . You
can com ­
pensate for this by pressing the brake pedal
more firmly . This a lso applies later when
new pads are installed.
- You shou ld perform braking maneuvers for
the purpose of cleaning the brake system
only if road condit ions permit. Other road
users must not be put at r isk - you may
cause an accident!
- Before descending a steep grade, reduce
speed a nd sh ift transmission into a lower
95

Care and cleaning
wash operator to reduce the risk of acci­
dents.
- To reduce the risk of cuts, protect yourself
from sharp metal components when wash­ ing the underbody or the inside of the wheel
housings.
- After washing the vehicle, the braking effect
may be delayed due to moisture on the
brake rotors or ice in the winter. This in­
creases the risk of an accident. The brakes
must be dried first with a few careful brake
applications.
(D Note
- If you wash the vehicle in an automatic car
wash, you must fold the exterior mirrors in
to reduce the risk of damage to the mirrors.
Power folding exterior mirrors* must only
be folded in and out using the power folding
function.
- To reduce the risk of paint damage, do not
wash the vehicle in direct sunlight. -
To reduce the risk of damage to the surface,
do not use insect removing sponges, kitchen
sponges or similar items.
- Matte finish painted vehicle components:
- To reduce the risk of damage to the sur-
face, do not use polishing agents or hard
wax.
- Never use protective wax. It can destroy
the matte finish effect.
- Do not place any stickers or magnetic
signs on vehicle parts painted with matte
finish paint. The paint could be damaged
when the stickers or magnets are re­
moved.
@ For the sake of the environment
Only wash the veh icle in facilities spec ially de­
signed for that purpose. This will reduce the
risk of dirty water contaminated with oil from
entering the sewer system.
