Driving and environment
- Never put too much motor oil in your engine=> page 285,
"Adding engine oil~".
- Never try to pus h- or tow-sta rt your vehicle.
The catalytic converter is an efficient "clean-up" dev ice built into the
exhaust system of the vehicle. The catalytic converter burns many of
the pollutants in the exhaust gas before they are released into the
atmosphere.
T he exclusive use of unleaded fuel is c riti cal ly import ant for the life of
the catalytic converter and proper funct io ni ng of the eng ine.
& WARNING
• Do not park or operate the vehicle in areas where the hot
exhaust sy stem may come in conta ct with dry gras s, brush, fuel
spill or other material which can cause a fire.
• Do not apply addit ional undercoat ing or rustproofing on or
near the exhaust manifold , exhau st pipes , catalytic converte r or
heat shield s. During driving, the sub stan ce u sed f or under coating
c ould o ve rheat and cause a fire.
0 Note
• Be aware that just one tank filling with leaded fuel w ill already
ser iously degr ade the performance of the ca talytic co nve rter.
• Do not exceed the correct engine oil level =>
page 285.
• Do not dr ive until the f uel tank becomes com plete ly empty . T he
engine could misfire . Unburned fuel cou ld also get into the ex ha ust
system 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 u nder these conditions, as
otherwise f uel can reac h the c ata ly tic conve rter. This co uld res ult in
over heat ing of the converter, requir ing its replacement.
• T o ass ure eff icien t operat ion of the Emission Cont rol System: -
Have your vehicle maintained properly and in accordance with
th e se rvice reco mmend ations in your W arran ty
& M ain ten ance
booklet.
- Lack of prope r main ten anc e as well as imp roper use of the
veh icle w ill impair the fu nction of the emission control system and
c o uld l ead to d amage.
~ For the sake of the environment
Even when the Emission Contro l System is operat ing proper ly, the
exhaust gas can have a sulfur-like exhaust gas smell u nder some
operating states. This depends on t he sulfur content of the fue l being
used . Using a different brand of fuel may help , o r fil lin g the tank with
lead-free supe r grade gasoline. •

Trailer towing
"-------------------------------------------------
Trailer load distribution
Be sure the load in the trailer is held securely in pla ce to prevent it
from shifting forward, backward or s ideways.
Never allow a passenger to ride in a trailer => & in "Driving instruc­
tions" on
page 256.
Engine cooling system
Towing a trailer makes the eng ine work harde r. It is important that
the cooling system's performance is up to the additional load. Make
sure that the cooling system has enough fluid.
Tire pressure
When towing a trailer, inflate the tires of your vehicle to the cold tire
pressure listed under "Full load" on the label located either on the
dr iver's side B-pillar (visible when the door is open) or inside the fuel
filler flap . Inflate trailer tires to trailer and tire manufacturers' spec­
ifications.
Lights
The headl ight settings should be checked w ith the trailer attached
before driving off. Check to make sure both vehicle and trai ler lights
are working properly.
Safety chains
Be sure trailer safety cha ins are properly connected from the trailer
to the hitch on the vehicle. Leave enough s lack in the chains to permit
turning corners. When you install safety chains, make sure they will
not drag on the road when you are driving.
T he chains should cross under the trailer tongue to p revent it from
dropping in case of separation from the hitch.
Driving instruct!ons
Driving with a trailer always requires extra care and
consideration.
To obtain the best possible handling of vehicle and trailer,
please note the following:
- Do not tow a loaded trailer when your car itself is not
loaded.
- Be especially careful when passing other veh icles .
- Observe speed limits.
- Do not drive at the maximum permissible speed.
- Always apply brakes early.
- Monitor the temperature gauge .
Weight distribution
Towing a loaded trailer w ith an empty car results in a highly unstable
distr ibution of weight. If this cannot be avoided, drive at very low
speeds only to avo id the r isk of losing steer ing control.
A "balanced" rig is easier to operate and control. Th is means that the
tow vehicle should be loaded to the extent possible and permissible,
wh ile keeping the trailer as light as possible under the c ircumstances.
Whenever possible, trans fer some cargo to the luggage compart ­
ment of the tow vehicle while observing tongue load requirements
and vehicle loading considerations.
Speed
Th e higher the speed, the more difficult it becomes for the driver to
control the r ig . Do not drive at the maximum permiss ible speed.
Reduce your speed even more if load, weather or wind conditions are
unfavorable -part icularly when go ing downhill.
Reduce vehicle speed
immediately i f the trailer shows the slightest
sign of swaying.
Do not try to stop the swaying by accelerating. _,

use a jet which sprays water in a
direct stream or one that has a
rotating j et.
Water temperature s hou ld not exceed 140
°F (60 °().
& WARNING
Never wash tires with a jet that sprays water in a direct stream.
This could cause invisible damage to the tires and weaken them ,
even if the spray is from a relatively long distance and for a short
time . Damaged and weakened tires can fail and cause accident s
and personal injury . .,_

Tires and wheels
Tires
General notes
Tires may be the least appreciated and most abused
parts of a motor vehicle.
T ir es may be the least apprec iated and most abused pa rts of a moto r
vehicle. Tires are, however, one of the most important parts of a
veh icle, parti cularly conside ring the comparative ly small patch of
rubber on eac h tire that assu res that all- important co ntact between
you , your ve hicle and the road .
Ma inta in ing t he correct t ire pressu re, making s ure that your veh icle
and i ts tires do not have to carry more weight than they can safely
hand le, avoid ing damage from road ha za rds and reg ula rly inspect ing
tires for damage incl ud ing c uts, s lashes irregular wea r and overall
condi tion are the mos t important th ings that you can do to help avoi d
sudden tire fa ilure includ ing t read separation and blowouts .
Avoiding damage
If you have to drive over a curb or sim ilar obstacle, drive very s lowly
and as close as poss ible at a right angle to the cu rb .
Always keep chemicals including grease, oil , gasoline and bra ke fl uid
o ff the t ires .
Inspect the ti res regularly for damage (cuts, crac ks o r bl ist ers, e tc .).
Remove any foreign bodies embed ded in the trea ds.
Storing tires
M ar k tires when yo u remove t hem to indica te the d irect ion of rota ­
tion . This ens ures yo u to be able to mo unt them co rrectly whe n you
re insta ll them.
Wh en r emoved, t he wheels or tires s hould be sto red in a c ool, dry and
preferably da rk p lace. Sto
re tires in a ver tica l pos it ion if they a re not mounted on rims, in a
hor izonta l position if they are mo unted on r ims.
New tires
N ew tires have to be bro ken in~ & .
Th e tread dep th of new tires may v ary, ac cor ding to t he type an d
make of t ire and the tread pattern.
Hidden damage
Dama ge to t ires and rims is often not readi ly visible . If yo u notice
unusu al v ib ra tion o r the veh icle pulls to one sid e, t his may i ndicate
that one of the tires has been damaged. The tires must be c hecke d
i m medi ately by an a uthor ized A udi deale r or quali fied w or ksh op .
Unidirectional tires
A u nidirectional tire can be identified by arrows on the sidewall, that
point in the d irect io n the tire is des igned to rotate. Yo u m ust follow
t he s peci fied dire ction of ro tation . T his is nece ssary so th at t hese
tires can develop the ir optimum c haracter istics regarding gr ip, road
noise, we ar and hy dropl aning res istance. For more informa tion
~page 326 .
& WARNING
New tires or tires that are old , worn or damaged cannot provide
maximum control and braking ability.
• New tires tend to be slippery and must also be broken-in. To
reduce the risk of losing control, a collision and serious personal
injuries , drive with special care for the first 350 miles (560 km).
• Driving with worn or damaged tires can lead to loss of control,
sudden tire failure , including a blowout and sudden deflation ,
crashes and serious personal injuries. Have worn or damaged tires
replaced immediately. .,_

& WARNING (co ntinued )
• Tires age even if they are not be ing used and can fail suddenly ,
e specially at high speeds . Tires that are more than 6 year s old can
only be used in an emergency and then with special care and at low
s peed .

Uniform Tire Quality Grading
is a tir e information system developed by the United States National
Highway Traffic Safety Administration (NHTSA) that is designed to
help buyers make relative comparisons among tires. The UTQG is not
a safety rating and not a guarantee that a tire will last for a prescribed
number of miles (kilometers) or perform in a certain way. It simp ly
gives tire buyers additional information to combine with other
considerations, such as price, brand loyalty and dealer recommenda­
tions. Under UTQG, tires are graded by the tire manufacturers in three
Safety first
