Diesel fuel of 52 to 54 cetane is used in  
your vehicle. If two types of diesel fuel  
are available, use summer or winter fuel  
properly according to the following tem-  
perature conditions.  
Biodiesel  
No special break-in period is needed. By  
following a few simple precautions for the  
first 1,000 km (600 miles) you may add to  
the performance, economy and life of  
your vehicle.  
Commercially supplied biodiesel blends  
of no more than 5% biodiesel, commonly  
known as "B5 biodiesel" may be used in  
your vehicle if it meets EN 14214 or  
equivalent specifications. (EN stands for  
"European Norm"). The use of biofuels  
made from rapeseed methyl ester  
(RME), fatty acid methyl ester (FAME),  
vegetable oil methyl ester (VME) etc. or  
mixing diesel with biodiesel will cause  
increased wear or damage to the engine  
and fuel system. Repair or replacement  
of worn or damaged components due to  
the use of non approved fuels will not be  
covered by the manufactures warranty.  
• Above -5°C(23°F) ... Summer type  
diesel fuel.  
• Below -5°C(23°F) ... Winter type diesel  
fuel.  
• Do not race the engine.  
• While driving, keep your engine speed  
(rpm, or revolutions per minute)  
between 2,000 rpm and 4,000 rpm.  
• Do not maintain a single speed for long  
periods of time, either fast or slow.  
Varying engine speed is needed to  
properly break-in the engine.  
• Avoid hard stops, except in emergen-  
cies, to allow the brakes to seat prop-  
erly.  
Watch the fuel level in the tank very care-  
fully : If the engine stops through fuel fail-  
ure, the circuits must be completely  
purged to restart.  
CAUTION  
• Do not let any gasoline or water  
enter the tank. This would make it  
necessary to drain it out and to  
bleed the lines to avoid jamming  
the injection pump and damaging  
the engine.  
• Don't let the engine idle longer than 3  
minutes at one time.  
• Don't tow a trailer during the first 2,000  
km (1,200 miles) of operation.  
CAUTION  
• Never use any fuel, whether  
diesel or B5 biodiesel that fails to  
meet the latest petroleum indus-  
try specification.  
• In winter, in order to cut down  
incidents due to freezing, paraffin  
oil may be added to the fuel if the  
temperature drops to below -  
10°C(50°F). Never use more than  
20% paraffin oil.  
• Never use any fuel additives or  
treatments that are not recom-  
mended or approved by the vehi-  
cle manufacturer.
