184 Intelligent technology
At higher speeds and with the windshield wip
ers turned on, the brake pads press against
the brake rotors for a short amount of time .
This occurs at regular intervals without the
driver noticing and provides for better brake
response time under wet condit ions .
The effectiveness of the brakes can be reduced
when the vehicle is dr iven on a salt-covered
road and the brakes are not used . Likew ise,
you clean
off accumulated sa lt coating from
brake discs and pads with a few caut ious ap
plications of the brake¢&. .
Cor ro sion
There may be a tendency for dirt to build up
on the brake pads and corrosion to form on
the discs if the car is not dr iven regularly or
only for short trips with l ittle use of the
brakes .
If the brakes are not used frequently , or if cor
rosion has formed on the discs, it is advisable
to clean
off the pads and discs by brak ing
firm ly a few times from a moderately high
speed ¢,& .
Fa ults in the brake system
If you should notice a sudden increase in
brake pedal travel, then one of the two brake
circu its may have failed¢&. .
Low brake fluid le vel
Malfunct ions can occur in the brake system if
the brake fluid level is too low. The brake fluid
leve l is monitored electronically .
Brake boost er
The brake booster increases the pressure that
you generate w ith the brake pedal. It works
only when the eng ine is running .¢ &.
Brake lining w ear status
Brake lining wea r may be checked by vis ual in
spection of the condition of the brake pads
through the openings in the whee l. If neces
sary, the whee l may be removed for this in
spection
¢ page 244, Changing a wheel.
_& WARNING
-New brake pads don't have the best stop
ping power and must be "broken -in" dur
ing the initial 100 to 150 miles (150 to
200 kilometers) of normal c ity driving .
You can compensate for this by pressing the brake pedal more firmly . T his also
applies later when new pads are instal led.
- You shou ld perform braking maneuvers
for the purpose of cleaning the brake system only if road conditions permit .
Othe r road users must not be put at risk -
you may ca use an accident!
- Before descend ing a steep grade, reduce
speed and sh ift transmission into a lower
gear or lower dr iving range. Do not ride
the brakes or hold the pedal down too
long o r too often . This could cause the
brakes to get hot and diminish braking
efficiency.
- Do not "ride the brakes" by rest ing you r
foot on the pedal when you do not intend
to b rake. This may cause the brakes to
overheat, p remature wear and increased
s topping distance.
- Unde r ce rtain cl imatic and ope rat ing
conditions such as passing thro ugh wa
ter, dr iving in heavy rain o r after washing
the vehicle, the effectiveness of the brakes can be reduced. In winter, ice can
accumu late on the brake pads, linings,
d iscs and drums. Carefully apply brakes
for a test. Brakes will dry and ice coat
ings will be cleaned
off after a few care
fu l brake applicat ions .
- Driving for an extended period of t ime on
salt-covered roads without using your brakes can a lso affect braking efficiency .
Clean
off accumulated salt coating from
b rake discs and pads wi th a few ca reful
b rake applications.
- I f you damage the front spoiler, or if you
install a different spoiler, be sure the a ir
flow to the front brakes is not obstruct-
ed . Otherwise the brake system could

A WARNING 1= ~
After driving through water, mud, slush, etc., the brakes may be slow to take effect
because of wet brake rotors and pads. Dry
the brakes first by braking carefully to re
store the full brak ing effect.
([) Note
Vehicle components such as the engine,
transmiss ion, suspension or electrical sys
tem can be severely damaged by driving
through wate r.
@ Tips
- Check the depth of the water before dr iv
i ng through it.
- Do not stop the veh icle, dr ive in reverse
or switch the engine off when driving
th rough water.
- Keep in mind that oncoming vehicles
may create waves that raise the water
level and make it too deep for you r vehi
cle to drive th rough safely.
- Avoid dr iving through sa lt water because
i t can ca use corrosion.
Catalytic converter
It is very important that your emission con
trol system (catalytic converter) is function
ing properly to ensure that your vehicle is run
ning in an environmentally sound manner.
11-Always use lead -free gaso line¢ page 201,
Fuel supply .
"'"Never run the tank down all the way to emp
ty.
11-Never put too much motor oil in your engine
¢ page 211, ~ Adding engine oil .
11-Never try to push -or tow -start your veh icle .
The catalytic converter is an efficient "clean up" device built into the exhaust system of
the vehicle . The catalytic converter burns
many of the pollutants in the exhaust gas be
fore they are released into the atmosphere .
Drivin g and en vironm ent 18 9
The exclusive use of unleaded fuel is critically
important for the life of the catalytic convert
er and proper f unct ion ing of the engine.
A WARNING
- The temperature of the exhaust system
is high, both when driving and after stop
ping the eng ine.
- Never touch the exhaust tail pipes once
they have become hot. This could result in burns.
- Do not park or operate the vehicle in
areas where the hot exhaust system may
come in co ntact with dry grass, br ush,
fue l spill or other material wh ich can
cause a fire .
- Do not apply additional undercoating or
ru stp roof ing on or nea r the exhaust
manifold, exhaust pipes, cataly tic con
ve rter or heat shield s. Dur ing driving, the
substance used for undercoating could
overheat and cause a fire.
(D Note
- Be aware that just o ne tank filling with
leaded fuel w ill already ser iously de
grade the performance of the catalytic
converter .
- Do not exceed the cor rect engine oil level
¢ page 211.
-Do not drive until the f ue l t ank becomes
comple tely empty . The engine co uld m is
fire . Unburned fuel could also get into
the exhaust system and this co uld cause
the catalytic converter to overheat.
- Do not turn off the ignition while the ve
hicle is mov ing.
- Do not continue to operate your vehicle
under these conditions, as othe rwise fuel
can reach the catalyt ic converter. Th is
cou ld result in overheating of the con
verter, requir ing its replacement.

A WARNING
-Only wash the vehicle when the ignition
is off and follow the instructions from
the car wash operator to reduce the risk of accidents .
- To reduce the r isk of cuts, protect your
self from sharp metal components when
wash ing the underbody or the inside of
t he wheel housings.
- After washing the vehicle, the braking ef
fec t may be delayed due to mo isture on
the brake rotors or ice in the winter. The
brakes must be dried first with a few
careful brake applications.
Q) Note
- If you wash t he vehicle in an automatic
car wash, yo u must fold the exterior m ir
rors in to reduce the r is k of damage to
the mirrors. Power folding exterior mir
rors* must only be folded in and out us
ing the power folding function.
- To prevent paint damage, do not wash
the vehicle in direct sunlight . -
To reduce the risk of damage to the sur
face, do not use insect removing spong
es, kitchen sponges or similar items.
- Matte finish painted vehicle compo
nents:
- To reduce the risk of damage to the surface, do not use polishing agents or hard wax.
- Never use car wash cycles that apply protective wax.
It can destroy the
matte fi nish effect.
- Do not place any stickers or magnet ic
signs on vehicle parts painted w ith
matte fi nish paint. The paint cou ld be
damaged when the stickers o r magnets
are removed.
@ For the sake of the environment
Only wash the vehi cle in facilities spec ial ly
designed for that purpose . This will red uce
the risk of dirty water contam inated with
oil from entering the sewer system.
