maintenance schedule DODGE CHALLENGER 2018 User Guide

Routine fluid and filter changes are not required. However,
change the fluid and filter if the fluid becomes contami-
nated (with water, etc.), or if the transmission is disas-
sembled for any reason.
All Wheel Drive (AWD) — If Equipped
The all wheel drive system consists of a transfer case and
front differential. The exterior surface of these components
should be inspected for evidence of fluid leaks. Confirmed
leaks should be repaired as soon as possible.
The transfer case fluid fill/inspection plug is located in the
middle of the rear housing. To inspect the transfer case
fluid level, remove the fill/inspection plug. The fluid level
should be even with the bottom of the hole. Use this plug
to add fluid as required.
The front differential fill plug is located on the outer cover
near the halfshaft attachment. To inspect the differential
fluid level, remove the fill plug. The fluid level should be
even with or slightly below the bottom of the hole.
Fluid Changes
Refer to “Scheduled Servicing” in “Servicing And Mainte-
nance” for the proper maintenance intervals.
Rear Axle
Fluid Level Check
Checking the fluid level while the vehicle is on level
ground and has been stationary for 15 minutes will im-
prove the accuracy of the fluid level reading.
Check the fluid level by removing the fill plug on the axle.
The fluid level should be 1-2.5 mm below the fill plug. Add
fluid, if necessary, to maintain the proper level. Refer to
“Fluids And Lubricants” inServicing And Maintenance”
for further information.

nance” for the proper maintenance intervals.

Tread Wear Indicators
Tread wear indicators are in the original equipment tires to
help you in determining when your tires should be re-
placed.
These indicators are molded into the bottom of the tread
grooves. They will appear as bands when the tread depth
becomes a 1/16 of an inch (1.6 mm). When the tread isworn to the tread wear indicators, the tire should be
replaced. Refer to “Replacement Tires” in this section for
further information.
Life Of Tire
The service life of a tire is dependent upon varying factors
including, but not limited to:
•
Driving style.
• Tire pressure - Improper cold tire inflation pressures can
cause uneven wear patterns to develop across the tire
tread. These abnormal wear patterns will reduce tread
life, resulting in the need for earlier tire replacement.
• Distance driven.
• Performance tires, tires with a speed rating of V or
higher, and Summer tires typically have a reduced tread
life. Rotation of these tires per the vehicle scheduled
maintenance is highly recommended.
WARNING!
Tires and the spare tire should be replaced after six
years, regardless of the remaining tread. Failure to
follow this warning can result in sudden tire failure.

CAUTION!(Continued)
important that only traction devices in good condi-
tion are used. Broken devices can cause serious
damage. Stop the vehicle immediately if noise occurs
that could indicate device breakage. Remove the
damaged parts of the device before further use.
• Install device as tightly as possible and then re-
tighten after driving about ½ mile (0.8 km).
• Do not exceed 30 mph (48 km/h).
• Drive cautiously and avoid severe turns and large
bumps, especially with a loaded vehicle.
• Do not drive for prolonged period on dry pavement.
• Observe the traction device manufacturer ’s instruc-
tions on the method of installation, operating speed,
and conditions for use. Always use the suggested
operating speed of the device manufacturer ’s if it is
less than 30 mph (48 km/h).
• Do not use traction devices on a compact spare tire.
Tire Rotation Recommendations
Tires on the front and rear axles of vehicles operate at
different loads and perform different steering, driving, and
braking functions. For these reasons, they wear at unequal
rates.
These effects can be reduced by timely rotation of tires. The
benefits of rotation are especially worthwhile with aggres-
sive tread designs such as those on all season type tires.
Rotation will increase tread life, help to maintain mud,
snow and wet traction levels, and contribute to a smooth,
quiet ride.
Refer to “Scheduled Servicing” in “Servicing And Mainte-
nance” for the proper maintenance intervals. The reasons
for any rapid or unusual wear should be corrected prior to
rotation being performed.
The suggested rotation method is the “rearward cross”
shown in the following diagram. This rotation pattern does
not apply to some directional tires that must not be
reversed.
