312 STARTING AND OPERATING
Maintenance
If you operate the vehicle using E-85 fuel, follow "Main-
tenance Schedule B." Refer to Section 8 of this manual.
CAUTION!
Do not use ethanol mixture greater than 85% in your
vehicle. It will cause difficulty in cold starting and
may affect driveability.
FUEL REQUIREMENTS — DIESEL
Diesel fuels are available from most reputable fuel mar-
keters. We encourage you to use only the best quality fuel
with a calculated Cetane Index of 50 or higher. In
addition, the manufacturer recommends using diesel fuel
with a sulfur content of less than 15 ppm. See your
authorized dealer or distributor for further information
regarding fuels available in your area.
In areas where diesel fuel is below the recommended
quality levels (high levels of sulfur and water) it is critical
to monitor the fuel filter for contamination and the
"Water-In-Fuel" message in the EVIC (Refer to Section 4).
Failure to properly service the fuel system for these items
can significantly reduce engine life and lead to major
engine repair. More frequent service intervals of the fuel
filter/water separator unit may be required under these
conditions than those shown in "Maintenance Schedule
A or B." See your authorized dealer or distributor for
specific information.
