CAUTION: (Continued)
Winter Fronts, Grille Covers or Obstructions:
Winter Fronts, grille covers or other add-on
equipment causing obstructions in front or
behind the fan should not be used on this
vehicle. If this causes the fan to eventually
break apart while it is rotating, the pieces can
cause severe injury to anyone nearby, such as
a service technician working on the engine,
and of course the pieces can severely damage
the vehicle.

Diesel Engine Fuel

Notice: Diesel fuel or fuel additives not
recommended in this manual could damage your
fuel system and engine. Your warranty would
not cover this damage. And:
•
Diesel fuel that has been mixed with engine oil
or automatic transmission fluid could damage
your engine and emission controls.
•
Aftermarket diesel fuel additives are not tested
by General Motors. Some additives, particularly
those which contain alcohol or water emulsifiers,
may damage your fuel system. If you believe that
unique circumstances call for a fuel additive to
be used, consult your dealer for advice.
•
If you ever run out of diesel fuel, it can be difficult
to restart your engine. To avoid all this, never let
your tank get empty.
If you run out of fuel, Running Out of Fuel on page 5-12
tells you how to restart your engine.
