check engine light DODGE HORNET 2023 Owner's Manual

266TECHNICAL SPECIFICATIONS
First tighten the lug nuts/bolts in a star pattern until each
nut/bolt has been tightened to 14.7 ft-lb (20 N·m). Then
repeat the operation until each lug nut/bolt has been
tightened to 88.5 ft-lb (120 N·m). Ensure that the socket is
fully engaged on the lug nut/bolt (do not insert it halfway).

Torque Pattern

After 25 miles (40 km), check the lug nut/bolt torque to be
sure that all the lug nuts/bolts are properly tightened.
FUEL REQUIREMENTS
While operating on gasoline with the required octane
number, hearing a light knocking sound from the engine is
not a cause for concern. However, if the engine is
heard making a heavy knocking sound, see a dealer
immediately. Use of gasoline with a lower than
recommended octane number can cause engine failure
and may void or not be covered by the New Vehicle Limited
Warranty.
2.0L ENGINE
This engine is designed to meet all emissions
requirements, and provide satisfactory fuel
economy and performance, when using
high-quality unleaded regular gasoline
having an octane rating of 87, as specified by the
(R+M)/2 method. The use of 91 or higher octane premium
gasoline will allow these engines to operate to optimal
performance. This increase in performance is most
noticeable in hot weather or under heavy load conditions
such as while towing.
REFORMULATED GASOLINE
Many areas of the country require the use of
cleaner-burning gasoline referred to as “reformulated
gasoline”. 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.
GASOLINE/OXYGENATE BLENDS
Some fuel suppliers blend unleaded gasoline with
oxygenates such as ethanol.
Problems that result from using gasoline containing more
than 15% ethanol (E-15) or gasoline containing methanol
are not the responsibility of the manufacturer and may
void the New Vehicle Limited Warranty.
WARNING!
To avoid the risk of forcing the vehicle off the jack, do
not tighten the lug nuts/bolts fully until the vehicle has
been lowered. Failure to follow this warning may result
in personal injury.
CAUTION!
DO NOT use E-85, gasoline containing methanol, or
gasoline containing more than 15% ethanol (E-15).
Use of these blends may result in starting and
drivability problems, damage critical fuel system
components, cause emissions to exceed the applicable
standard, and/or cause the Malfunction Indicator Light
to illuminate. Please observe pump labels as they
should clearly communicate if a fuel contains greater
than 15% ethanol (E-15).
