fi lling up yo ur vehicle.
Service stations offering Diesel f uel are generally loca ted on truck
routes or major hig hways. Directo ries of Diese l fue l stations are
usually availab le at Diese l fuel stations.

Diesel fuel may not be available outs ide the USA and Canada. Be sure
to check before trave ling to othe r countries .
Winter operation
At t empe ratures below 20° F (- 7° C), Die sel fue l No . 2 l oses its flu idity
due to wax separation, wh ich may clog the fuel filter or tank fi lter and
keep the engine from running .
T o help t he filte r from be ing clogged by wax, the fue l fi lter in your
vehicle is automatically preheated. Preheat ing the fuel f ilter makes
operat io n of yo ur vehicle possib le with Die sel fuel No. 2 dow n to -
10° F (-24° C).
If you expect temperat ures below 5° F (-1S° C) ask yo ur fuel dealer
whether their Diesel fuel No . 2 is suffic iently w interized for the
prevailing and expected temperat ures.
If not winterized or insuff ic ie ntly w inte riz ed Diese l fuel has already
thickened to the extent that the engine w ill not start, warm the
vehicle up by leaving i t in a heated garage.
It is normal that the eng ine noise level (dieseling) is louder during the
warm-up period in winte r. It is also normal when whitish -blue smoke
comes out of t he tailpipe afte r start ing and du ring warm-up. The
amount of smoke depends on the outside temperature .
Do not let your Diesel engine idle unnecessa rily af ter a co ld start.

Vehicle care Technical data

Fuel supply and filling your fuel tank
Your vehicle fuel tank has an on-board refuelling vapor recovery
system . This feature helps to prevent fuel vapors from escaping from
the tank and polluting the environment while you refuel your vehicle.
In order to fill the tank properly while protecting the environment,
please follow this refueling procedure carefully.
& WARNING
Under normal operating conditions, never carry additional fuel
containers in your car. Gas canisters and other containers used to
transport fuel can be dangerous. Such containers, 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 blower, etc., be very careful and always observe local and state laws regarding the use, trans­
portation and storage of such fuel containers. Make certain the
container meets industry standards (ANSI/ASTM F852 -86).
0 Note
Never drive your vehicle until the fuel tank is completely empty. The
ir regular supply of fuel can cause misfiring. Gasoline could enter the
exhaust system and damage the catalytic converter. •

fuel filler flap
When adding fuel, the ignition and any cellular phones in the
vehicle must be switched
off. When activating the central
locking, the fuel filler flap is automatically unlocked or
locked. Refuel the vehicle with the ignition turned
off.
Taking the fuel cap off
- To open the fuel filler flap, press on the left side of the
flap ~ fig. 224 -arrow-.
- Unscrew fuel filler cap counter-clockwise and hang it on
the fuel filler flap~ fig. 225.
- Check the label on the inside of the fuel filler flap to deter­
mine if the vehicle must be fueled with gasoline or diesel
fuel.
Refuelling procedure
- Insert the fuel nozzle from the gasoline pump into the
fuel filler neck as far as it will go.
- Select a medium refuelling rate so that the nozzle
switches off automatically when the tank is full.

Putting the fuel cap back on
- After filling your tank, twist the fuel fi ller cap c lockwise as
f ar as it w ill go.
- Close t he fue l fi ller flap.
To avoid fuel spi lling or evapo rating from the f uel tank a lways close
fue l filler cap properly and comp lete ly . An impro perly closed fuel
filler cap may also ca use the MIL lamp~
page 30 to come on (only
vehicle s wi th gaso lin e e ngine).
& WARNING
Improper refueling or handling of fuel can cause fire, explosion
and severe burns .
• Fuel i s highly flammable and can cause severe burns and other
injuries.
• Failure to shut the engine off while refueling and /or to insert
the pump nozzle fully into the fuel filler neck could cause fuel to spray out of filler n eck or to overflow. Fuel spray and ov erflowing
fuel can cause a fire.
• Never use a cellular telephone while refueling. The electromag­
netic radiation can cau se sparks that can ignite fuel vapors and
cause a fire.
• Never get back into your vehicle while refueling. If in excep­
tional cir cumstan ces you must get ba ck in your v ehicle while refu­
eling, make certain that you close the door and touch metal to
discharge static electricity before touching the filler nozzle again .
Static electricity can cause sparks that can ignite fuel vapo rs
released during refueling.
• Never smoke or have an open flame anywhere in o r near your
vehicle when refueling or filling a portable fue l container.
• For your safety , we strongly recommend that you do not travel
with a portable fuel container in your vehicle . The container , full
or empty may leak and could cau se a fire , especially in a crash.

& WARNING (co ntinued )
• If, under exceptional circumstances , you must tran sport a
portable fuel container, please observe the following:
-Never fill a portable fuel container while it is anywhere in or
on the vehicle (for example, in the luggage compartment, or
on the trunk ). Static electricity can build up while filling and
can ignite fuel vapors causing a fire .
- Always place a portable fuel container on the ground before
filling .
- Always keep the filler nozzle completel y inside the portable
container before and during filling.
- If filling a portable container made of metal, the filler nozzle must always be in contact with the container. This will help
prevent static ele ctricity from discharging and cause a fire .
- Ne ver spill fuel inside the vehicle or luggage compartment .
Fuel vapor s are highly flammable.
- Always observe local and state /provincial laws regarding the
use, storage and tran sportation of fuel containers .
-Make certain the fuel container meets industry standards
( ANSI / ASTM F852-86 ).
