BRAKE SYSTEM
Your vehicle is equipped with dual hydraulic brake
systems. If either of the two hydraulic systems loses
normal capability, the remaining system will still func-
tion. However, there will be some loss of overall brak-
ing effectiveness. You may notice increased pedal travel
during application, greater pedal force required to slow
or stop, and potential activation of the “Brake System
Warning Light”.
In the event power assist is lost for any reason (i.e.,
repeated brake applications with the engine off), the
brakes will still function. However, the effort required
to brake the vehicle will be much greater than that
required with the power system operating.
FUEL REQUIREMENTS — 1750 TURBO
The 1750 turbo engine is designed to
meet all emissions regulations and pro-
vide excellent fuel economy and perfor-
mance when using high-quality premium
unleaded gasoline with an octane rating
of only 91 or higher.
Light spark knock at low engine speeds is not harmful
to your engine. However, continued heavy spark knock
at high speeds can cause damage and immediate ser-
vice is required.
Poor quality gasoline can cause problems such as hard
starting, stalling and hesitations. If you experience these
symptoms, try another brand of gasoline (with the
appropriate octane rating for your engine) before con-
sidering service for the vehicle.
Reformulated Gasoline
Many areas of the country require the use of cleaner
burning gasoline referred to as “Reformulated Gaso-
line”. Reformulated gasoline contains oxygenates and
are specifically blended to reduce vehicle emissions and
improve air quality.
The use of reformulated gasoline is recommended.
Properly blended reformulated gasoline will provide
improved performance and durability of engine and
fuel system components.
