2021 DODGE CHARGER check engine

TECHNICAL SPECIFICATIONS297
Tighten the lug nuts/bolts in a star pattern until
each nut/bolt has been tightened twice. Ensure
that the socket is fully engaged on the lug nut/bolt
(do not insert it halfway).
NOTE:If in doubt about the correct tightness, have them
checked with a torque wrench by an authorized
dealer or service station.
After 25 miles (40 km), check the lug nut/bolt
torque to be sure that all the lug nuts/bolts are
properly tightened.

Torque Patterns

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 the
New Vehicle Limited Warranty.
Poor quality gasoline can cause problems such
as hard starting, stalling, and hesitations. If you
experience these symptoms, try another brand of
gasoline before considering service for the vehicle.
3.6L ENGINE
This engine is designed to meet all
emissions regulations and provide
excellent 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 higher octane
premium gasoline will not provide any benefit over
regular gasoline in these engines.
5.7L ENGINE
Do not use E-85 flex fuel or ethanol blends greater
than 15% in this engine.

This engine is designed to meet all
emissions regulations and provide
satisfactory fuel economy and
performance when using high-quality
unleaded gasoline having an octane range of 87
to 89 as specified by the (R+M)/2 method. The use
of 89 octane plus gasoline is recommended for
optimum performance and fuel economy.

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.
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.
