Vehicle care Technical data

Driving and environment
New brake pads
Remember that new brake pads do not have a f ull braki ng
e ff e ct during the first 250 miles (400 kilometers) after they
are i nsta lle d.
New bra ke pads have to be "b ur nished in " before they have opt ima l
grab=> &.
Dur ing the break -in period, you sho uld avoid putting severe loads on
the brakes . Severe loads incl ude, for example, sudden hard braki ng,
in particu lar at very high s peeds or, for examp le, on mountai n passes.
& WARNING
New brake pads don 't have the be st stopping power and must be
" broken -in " during the initial 100 to 150 miles (150 to 200 kilo­
meters ) of normal cit y driving. You can compensate for thi s by
pressing th e brak e pedal more firmly. This also applies lat er wh en
new pad s are installed. n
Avoid damaging the vehicle
W hen yo u are d riving on poor roads, or over c urbs, steep ram ps, etc.,
ma ke c ert ain that low-lying pa rts such as spoilers and exhaust system
parts do not bottom out and get damage d.
Thi s is espe cially t rue for veh icle s wi th low-slung chass is (spor ts
chassis)* and fully loaded vehicles.
Driving through water on roads
Note the following to avoid vehicle damage when driving throug h
water, fo r example on flooded roads: •
The water must not be any higher than the bottom of the vehicle
body .
• Do not dr ive faster than wa lking speed.
& WARNING
After driving through water , mud, slush , etc. , the brake s may be
slow to take effect because of wet brake rotors and pads.
Dry the
brakes first by braking carefully to restore the full b rak ing effect.
0 Note
Vehicle components such as the engine, transmission, suspension o r
elect rical sys tem can be seve rely damaged by dr iv ing t hrough w ater.
[ i ] Tips
• Check t he de pth of the wa ter bef ore dr iv ing thro ugh it.
• Do not stop the vehicle, drive in reverse or switch the engine off
when drivi ng throug h wate r.
• Keep in mind that oncoming vehicles may create waves t hat raise

• Avoid dr iv ing through sa lt water because i t can cause corros ion. •
Catalytic converter
--
It is very impor tant that your emission control system
(catalyti c converter) is functioning properly t o ensure
that y our vehicle i s run ning i n an en viro nme ntally sou nd
man ner.
- A lways us e lead-fr ee gasoline=> page 271, "F uel supp ly".
- N ever run the tan k down all the way to empty. .._

Driving and environment
------------------------------------------------'
-Nev er p ut too much motor oil in yo ur eng ine=:> pag e 282 ,
"A dd ing eng ine o il 't=:r.".
- N ever try to push- or tow-star t your ve hicle.
Th e catalyt ic conve rter is an eff ic ient "clean-up" device built into the
ex ha ust system of the vehicle . The catalytic converter burns many of
t he pollu tan ts i n the exhaust gas be fore they are re leased into the
atmosphere.
Th e excl usive use o f un leaded fuel is crit ic all y import ant for the lif e of
the catalytic converter and proper funct io ni ng of the engine.
& WARNING
• Do not park or ope rate the vehicle in areas where the hot
exhaust sy stem may come in conta ct with dry grass, bru sh, fuel
spill or othe r materi al which can cause a fire .
• Do not apply additional undercoating or rustproofing on or
near the exhaust manifold , exhaust p ipes , catalytic converter or
heat shi eld s. During driving, the sub stance u sed for und ercoating
could o verheat and cause a fire.
0 Note
• Be aware that just one tank filling w it h leaded fuel will already
ser iously degr ade the performance of the catalyt ic converter.
• Do not exceed the correct engine oi l level =>
page 282.
• Do not dr ive until t he fuel tank becomes com plete ly em pty. The
engine could misfire. Unbu rned fue l co uld also get into the exhaust
sys tem and t his co ul d cause t he ca talyt ic converter to ove rheat.
• Do not turn off the ignition while the vehicle is moving.
• Do not continue to operate your vehicle under these conditions, as
otherwise fuel can reac h the cata lyti c conve rter. This co ul d res ult in
over heat ing of the converter, requir ing its rep lacement.

~ For the sake of the environment
Even when the Emiss ion Contro l System is operating properly, the
exhaust gas can have a s ulfur-like exhaust gas smell under some
operating states . This depends on the sulfur content of the fue l being
used. Using a differe nt brand of fuel may help, or filli ng the tank with
lead-free super g rade gasoline. •
Operate your vehicle economically
and minimize pollution
General
Yo ur p ersonal sty le o f driving will determine the eco nom y
of your vehicle, as well as exhaust and noise levels .
Fuel economy, envi ronmenta l impact, and wear on your engine,
bra kes and tires la rgely depend on t hree fac to rs:
• your persona l dr iv ing style
• operati ng conditio ns
• technical limitations
If you an tici pat e wh at yo u nee d to do nex t an d drive eco no m ic ally,
you can easily cut your fuel consumpt io n by 10-15 percent. This

Vehicle care Do-it-yourself service Technical data

Driving and environment
------------------------------------------------'
The amount of oil used is related to engine load and speed.
It is normal for the oil consumption of a new engine to reach its
lowest value after a certain mileage has been driven .
You must drive your vehicle about 3,000 miles (5,000 kilometers)
before you can properly assess oil consumption.
This also applies to fuel consumption and engine output .
0 Note
• Have your vehicle maintained properly and in accordance with the
service recommendations in your Warranty
& Maintenance booklet.
Lack of proper maintenance as well as improper use of the vehicle w ill
impair the function of the emission control system and cou ld lead to
damage.
• Do not alter or remove any component of the Emission Control
System un less approved by the manufacturer.
• Do not a lter or remove any device, such as heat shie lds, switches,
ignition wires, valves, which are designed to protect your vehicle's Emission Contro l System and other important vehicle components. •
Fewer short trips
Fuel consumption will always be relatively high on short
trips .
-Try to avoid driving short distances with a cold engine.
The eng ine and catalytic converter have to reach thei r optima l oper­
ating temperature
to reduce fuel consumption and noxio us em is­
sions effectively.
Just after starting, a cold engine in a mid -size car only achieves a fuel
economy of 6-8 miles per gallon (30-40 l/l00km). After about a half
a mile, fuel economy climbs to 12 mpg (20 l/100 km). After about
2.5 miles (4 km), the engine is at its proper operating temperature
Controls and equip­
ment Safety first Vehicle operation
and fuel economy has
reached a normal level. So you can see that you
should avoid short trips whenever possible.
The
outside temperature is also cr it ical in th is regard . Your car
consumes more fuel in the winter than in the summer. •
