2018 DODGE CHALLENGER SRT check engine

Clean the top of the master cylinder area before removing
the cap. Add fluid to bring the level up to the top of the
“FULL” mark on the side of the master cylinder reservoir.
Overfilling of fluid is not recommended because it may
cause leaking in the system.
Add enough fluid to bring the level up to the requirements
described on the brake fluid reservoir. With disc brakes,
fluid level can be expected to fall as the brake pads wear.
However, low fluid level may be caused by a leak and a
checkup may be needed.
Use only brake fluid that has been recommended by the
manufacturer, and has been kept in a tightly closed con-
tainer to avoid contamination from foreign matter or
moisture.
Refer to “Fluids And Lubricants” in “Technical Specifica-
tions” for further information.
WARNING!
•Use only manufacturer’s recommended brake fluid.
Refer to “Fluids And Lubricants” in “Technical
Specifications” for further information. Using the

wrong type of brake fluid can severely damage your
brake system and/or impair its performance. The
proper type of brake fluid for your vehicle is also
identified on the original factory installed hydraulic
master cylinder reservoir.
• To avoid contamination from foreign matter or mois-
ture, use only new brake fluid or fluid that has been
in a tightly closed container. Keep the master cylin-
der reservoir cap secured at all times. Brake fluid in
a open container absorbs moisture from the air
resulting in a lower boiling point. This may cause it
to boil unexpectedly during hard or prolonged brak-
ing, resulting in sudden brake failure. This could
result in a collision.
• Overfilling the brake fluid reservoir can result in
spilling brake fluid on hot engine parts, causing the
brake fluid to catch fire. Brake fluid can also damage
painted and vinyl surfaces, care should be taken to
avoid its contact with these surfaces.
• Do not allow petroleum based fluid to contaminate
the brake fluid. Brake seal components could be
damaged, causing partial or complete brake failure.
This could result in a collision.

SERVICING AND MAINTENANCE 341

CAUTION!
Using a transmission fluid other than the manufactur-
er ’s recommended fluid may cause deterioration in
transmission shift quality and/or torque converter
shudder. Refer to “Fluids And Lubricants” in “Techni-
cal Specifications” for fluid specifications.
Special Additives
The manufacturer strongly recommends against using any
special additives in the transmission. Automatic Transmis-
sion Fluid (ATF) is an engineered product and its perfor-
mance may be impaired by supplemental additives. There-
fore, do not add any fluid additives to the transmission.
Avoid using transmission sealers as they may adversely
affect seals.
CAUTION!
Do not use chemical flushes in your transmission as
the chemicals can damage your transmission compo-
nents. Such damage is not covered by the New Vehicle
Limited Warranty.
Fluid Level Check
The fluid level is preset at the factory and does not require
adjustment under normal operating conditions. Routine
fluid level checks are not required; therefore the transmis-
sion has no dipstick. An authorized dealer can check your
transmission fluid level using special service tools. If you
notice fluid leakage or transmission malfunction, visit an
authorized dealer immediately to have the transmission
fluid level checked. Operating the vehicle with an im-
proper fluid level can cause severe transmission damage.
CAUTION!
If a transmission fluid leak occurs, visit an authorized
dealer immediately. Severe transmission damage may
occur. An authorized dealer has the proper tools to
adjust the fluid level accurately.
Fluid And Filter Changes
Under normal operating conditions, the fluid installed at
the factory will provide satisfactory lubrication for the life
of the vehicle.

SERVICING AND MAINTENANCE 343

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 half-
way).
NOTE:If in doubt about the correct tightness, have them
checked with a torque wrench by your 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 seated against
the wheel.WARNING!
To avoid the risk of forcing the vehicle off the jack, do
not tighten the lug nuts fully until the vehicle has been
lowered. Failure to follow this warning may result in
personal injury.
FUEL REQUIREMENTS
6.2L Supercharged Engine
Do not use E-85 flex fuel or ethanol blends greater than
15% in this engine.
These engines are designed to meet all
emissions regulations, provide optimal
fuel economy and performance when
using high-quality unleaded “Pre-
mium” gasoline having a posted octane
number of 91 as specified by the
(R+M)/2 method. The use of 91 or
higher octane “Premium” gasoline is required in these
engines.
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
