184 Cleaning and protection
Fabrics and fabric coverings
Fab rics and fabr ic coveri ngs (e.g. seats, door
tr im panels, etc.) should be cleaned at reg ular
inte rva ls with a vacuum cleaner. This removes
sur face dirt particles which could become em­
bedded in the fabric through use. Steam
cleaners shou ld not be used, because the
steam tends to push the dirt deeper into the
fabric and lock it there.
Normal cleaning
Generally, we recommend using a soft sponge
or a lint-free microfiber cloth to the clean fab ­
ric. Brushes should on ly be used for carpets
and floor mats, s ince other fabric surfaces
could be harmed by brushes.
Normal surface stains can be cleaned using a
commercially available foam cleaner. Spread
the foam on the surface of the fabric with a
soft sponge and work it in gently. Do not satu­
rate the fabric. Then pat the foam d ry using
absorbent, dry cloths (e.g . microfiber cloth)
and vacuum it afte r it has dried comp lete ly.
Cleaning stain s
Stains caused by beverages (e.g. coffee, fruit
ju ice, etc.) can be treated with a mild deter­
gent solut ion. App ly the detergent so lution
with a sponge. In the case of stubbor n stains,
a detergent paste can be applied directly to
the sta in and wor ked into the fabric. Afte r­
wards, use copio us amo unts o f cle an water to
remove t he remaining dete rgent. Apply the
water with a damp cloth or sponge and pat
the fabric d ry w ith an absorbent, dry cloth.
S tains from chocola te or make up s hou ld have
detergent paste (e .g. ox -gall soap) r ubbed in ­
to them. Afterwards, remove the soap with
water (damp sponge).
A lcohol can be used to t rea t stains from
g rease, oi l, lips tick or a ballpo in t pen . Me lted
grease or dye must be patted off using ab ­
sorbent materia l. It may be necessary to re­
treat the areas with dete rgent paste and wa­
ter. In the case of gene
ra l soiling o f the uphols ­
tery and cover material, we recommend hiring
a spec ia list that has the equipment to clean
the seat covers and other fabr ic surfaces by
shampooing and spray extraction.

Cleaning and protec tion
Engine compartment
Be especially careful when cleaning the en­
gine compartment.
A lw ays switch o ff the ign it ion before cle an ­
i ng the eng ine
c> ,& .
Plenum pan el
Remove leaves from the plenum panel in front
of the windshield under the engine hood. This
prevents the water drain holes from becoming
blocked, and it prevents debris from enter ing
the vehicle interior through the heating and
vent ilat ion ducts.
Co rro sio n protect ion
The engine compartment and transmission
have been corrosion-protected at the factory.
Good anti -corrosion treatment is very impor­
tant, partic ularly in the winter.
If the vehicle
is frequently driven on salt treated roads, the
entire engine compartment and p lenum panel
should be thoroughly cleaned at the end of
winter and retreated to prevent salt damage.
At the same time, the underside of the vehicle
shou ld be washed as well.
If the engine compartment is cleaned at any
time with grease remov ing solutions
1> , or if
you have the engine washed, the anti-corro­
s ion treatment is almost always removed as
well.
It i s therefo re essentia l to have a long­
lasti ng cor rosion pro tect ion reapplied to all
surfaces, seams, joints and components in the
engine compartment .
A WARNING
Be aware: The engine compartment of any
motor vehicle is a potentially hazardous
area.
- Before work ing in the engine compart­
ment, be sure to read the information

Winter operation
At temperatures below 20° F (-7° C), Diesel
fuel No.
2 loses its fluidity due to wax separa­
tion, which may clog the fuel filter or tank fil­
ter and keep the engine from running .
To help the filter from being clogged by wax,
the fuel filter in your vehicle is automatically
preheated. Preheating the fuel filter makes
operation of your vehicle possible with Diesel
fuel No . 2 down to -10° F (-24° C).
If you expect temperatures below
5° F
(-15° C)
ask your fuel dealer whether their
Diese l fuel No.
2 is sufficiently winterized for
the prevailing and expected temperatures.
If not winterized or insufficiently winterized
d iesel fue l has already thickened to the extent
that the engine will not start, warm the vehi­
cle up by leaving it in a heated garage.
It is normal that the engine noise leve l (die­
seling) is louder during the warm-up period in
winter.
It is also norma l when whitish-blue
smoke comes out of the tailpipe after start ing
and during warm-up . The amount of smoke
depends on the outs ide temperature.
Do not let your diesel engine idle unnecessari­
ly after a cold start. Driving off slowly will
shorten the warm-up period .
A WARNING
-Never use "starting assist fluids." They
may be potent ially explosive or cause a
"run-away" engine condition. This could
result in serious engine damage and per­
sonal injury.
- Never use fuel line anti-freeze offered for
gasoline engines .
0 Note
- Your diesel engine has been specifically
designed to operate only on Ultra Low
Sulfur Diesel fuel. Therefore, never use
home heating oil or regular gasol ine. Th e
properties of these fuels may cause seri­
ous damage to the fuel injection system
and to the engine. Using these fuels can
-
Fuel supply and filling your fuel tank 191
cause expensive engine repai rs and will
also adversely affect your New Vehicle
Limited Warranty.
- If diesel fuel should get on any rubber
hose, it must be wiped off immediately.
Then wash the contaminated hose por­
tion with soap and warm water. Do not
allow diesel fuel to remain on connecting
hoses. They may develop leaks and cause
ser ious damage.
Fuel tank
Fuel filler neck
The fuel filler neck is located on the right rear
side panel behind the fuel filler flap.
If the power locking system should fail, you
can still open the flap manually -for detailed

You can find the fuel tank capacity of your ve­
hicle in
Technical Data ¢page 257 .
The labe l on the inside of the fuel fi ller flap
tells you the correct fuel for your vehicle. For
more information about fuel specifications,
see
¢ page 189.
Your vehicle fuel tank has an on-board refuel­
ling vapor recovery system. This feature helps
to prevent fuel vapors from escaping from the
tank and polluting the environment while you refue l your vehicle. In order to fi ll the tank
properly while protecting the environment,
please follow this refueling procedure careful­
ly.
A WARNING
Under normal operating conditions, never
carry addit ional fuel conta iners in your car .
Gas canisters and other containers used to
transport fuel can be dangerous. Such con­
tainers, full or empty, may leak and could
cause a fire in a collision. If you must
transport fuel to use for your lawn mower,
snow b lower, etc., be very careful and al­
ways observe loca l and state laws regard­
ing the use, transportation and storage of
such fuel containers. Make certain the
