2018 DODGE CHALLENGER tires

•Do not drive more than 50 mph (80 km/h) when towing
while using a full size spare tire.
• Proper tire inflation pressures are essential to the safe
and satisfactory operation of your vehicle. Refer to
“Tires” in “Servicing And Maintenance” for proper tire
inflation procedures.
• Check the trailer tires for proper tire inflation pressures
before trailer usage.
• Check for signs of tire wear or visible tire damage before
towing a trailer. Refer to “Tires” in “Servicing And
Maintenance” for the proper inspection procedure.
• When replacing tires, refer to “Tires” in “Servicing And
Maintenance” for the proper tire replacement proce-
dures. Replacing tires with a higher load carrying capac-
ity will not increase the vehicle’s GVWR and GAWR
limits.
Towing Requirements — Trailer Brakes
• Do not interconnect the hydraulic brake system or
vacuum system of your vehicle with that of the trailer.
This could cause inadequate braking and possible per-
sonal injury. •
An electronically actuated trailer brake controller is
required when towing a trailer with electronically actu-
ated brakes. When towing a trailer equipped with a
hydraulic surge actuated brake system, an electronic
brake controller is not required.
• Trailer brakes are recommended for trailers over
1,000 lbs (453 kg) and required for trailers in excess of
2,000 lbs (907 kg).
WARNING!
• Do not connect trailer brakes to your vehicle’s hy-
draulic brake lines. It can overload your brake sys-
tem and cause it to fail. You might not have brakes
when you need them and could have a collision.
• Towing any trailer will increase your stopping dis-
tance. When towing you should allow for additional
space between your vehicle and the vehicle in front
of you. Failure to do so could result in a collision.
CAUTION!
If the trailer weighs more than 1,000 lbs (453 kg)
loaded, it should have its own brakes and they should

DRIVING TIPS
Driving On Slippery Surfaces
Information in this section will aid in safe controlled
launches in adverse conditions.
Acceleration
Rapid acceleration on snow covered, wet, or other slippery
surfaces may cause the driving wheels to pull erratically to
the right or left. This phenomenon occurs when there is a
difference in the surface traction under the rear (driving)
wheels.
WARNING!
Rapid acceleration on slippery surfaces is dangerous.
Unequal traction can cause sudden pulling of the rear
wheels. You could lose control of the vehicle and
possibly have a collision. Accelerate slowly and care-
fully whenever there is likely to be poor traction (ice,
snow, wet, mud, loose sand, etc.).
Traction
When driving on wet or slushy roads, it is possible for a
wedge of water to build up between the tire and road
surface. This is known as hydroplaning and may cause
partial or complete loss of vehicle control and stopping
ability. To reduce this possibility, the following precautions
should be observed:
•Slow down during rainstorms or when the roads are
slushy.
• Slow down if the road has standing water or puddles.
• Replace tires when tread wear indicators first become
visible.
• Keep tires properly inflated.
• Maintain sufficient distance between your vehicle and
the vehicle in front of you to avoid a collision in a
sudden stop.
Your vehicle may be equipped with a Limited Slip Differ-
ential (LSD) that reduces, but does not eliminate, the
amount of wheel slip across a given axle for improved
handling.

JACKING AND TIRE CHANGING
WARNING!
•Do not attempt to change a tire on the side of the
vehicle close to moving traffic. Pull far enough off
the road to avoid the danger of being hit when
operating the jack or changing the wheel.
• Being under a jacked-up vehicle is dangerous. The
vehicle could slip off the jack and fall on you. You
could be crushed. Never put any part of your body
(Continued)
WARNING! (Continued)
under a vehicle that is on a jack. If you need to get
under a raised vehicle, take it to a service center
where it can be raised on a lift.
• Never start or run the engine while the vehicle is on
a jack.
• The jack is designed to be used as a tool for changing
tires only. The jack should not be used to lift the
vehicle for service purposes. The vehicle should be
jacked on a firm level surface only. Avoid ice or
slippery areas.

7. Mount the spare tire.
CAUTION!
Do not attempt to raise the vehicle by jacking on
locations other than those indicated.NOTE:
•For vehicles so equipped, do not attempt to install a
center cap or wheel cover on the compact spare.
• Refer to “Compact Spare Tire” and to “Limited-Use
Spare” under “Tires—General Information” in “Servic-
ing And Maintenance” for additional warnings, cau-
tions, and information about the spare tire, its use, and
operation.
8. Install the lug nuts with the cone shaped end of the lug nut toward the wheel. Lightly tighten the lug nuts.
WARNING!
To avoid the risk of forcing the vehicle off the jack, do
not tighten the wheel nuts fully until the vehicle has
been lowered. Failure to follow this warning may
result in serious injury.
9. Lower the vehicle to the ground by turning the jack handle counterclockwise.
10. Refer to “Torque Specifications” in “Technical Specifi- cations” section for proper lug nut torque.
Mounting Spare Tire
296 IN CASE OF EMERGENCY

•When the Tire Service Kit sealant is in a liquid form,
clean water and a damp cloth will remove the material
from the vehicle or tire and wheel components. Once the
sealant dries, it can easily be peeled off and properly
discarded.
• For optimum performance, make sure the valve stem on
the wheel is free of debris before connecting the Tire
Service Kit.
• You can use the Tire Service Kit air pump to inflate
bicycle tires. The kit also comes with two needles,
located in the Accessory Storage Compartment (on the
bottom of the air pump) for inflating sport balls, rafts, or
similar inflatable items. However, use only the Air Pump
Hose (7) and make sure the Mode Select Knob (5) is in
the Air Mode when inflating such items to avoid inject-
ing sealant into them. The Tire Service Kit Sealant is only
intended to seal punctures less than 1/4 inch (6 mm)
diameter in the tread of your tire.
• Do not lift or carry the Tire Service Kit by the hoses.WARNING!
•Do not attempt to seal a tire on the side of the vehicle
closest to traffic. Pull far enough off the road to avoid
the danger of being hit when using the Tire Service
Kit.
• Do not use Tire Service Kit or drive the vehicle under
the following circumstances:
– If the puncture in the tire tread is approximately 1/4 inch (6 mm) or larger.
– If the tire has any sidewall damage.
– If the tire has any damage from driving with extremely low tire pressure.
– If the tire has any damage from driving on a flat tire.
– If the wheel has any damage.
– If you are unsure of the condition of the tire or the wheel.
• Keep Tire Service Kit away from open flames or heat
source.
• A loose Tire Service Kit thrown forward in a collision
or hard stop could endanger the occupants of the
vehicle. Always stow the Tire Service Kit in the place
provided. Failure to follow these warnings can result

least one minute after every five rocking-motion
cycles. This will minimize overheating and reduce the
risk of clutch or transmission failure during prolonged
efforts to free a stuck vehicle.
NOTE: Push the “ESC Off” switch (if necessary), to place
the Electronic Stability Control (ESC) system in “Partial
Off” mode, before rocking the vehicle. Refer to “Electronic
Brake Control System” in “Safety” for further information.
Once the vehicle has been freed, push the ESC Offswitch
again to restore “ESC On” mode.
WARNING!
Fast spinning tires can be dangerous. Forces generated
by excessive wheel speeds may cause damage, or even
failure, of the axle and tires. A tire could explode and
injure someone. Do not spin your vehicle’s wheels
faster than 30 mph (48 km/h) or for longer than 30
seconds continuously without stopping when you are
stuck and do not let anyone near a spinning wheel, no
matter what the speed.
CAUTION!
• When “rocking” a stuck vehicle by shifting between
DRIVE / FIRST GEAR and REVERSE, do not spin
the wheels faster than 15 mph (24 km/h), or drive-
train damage may result.
• Revving the engine or spinning the wheels too fast
may lead to transmission overheating and failure. It
can also damage the tires. Do not spin the wheels
above 30 mph (48 km/h) while in gear (no transmis-
sion shifting occurring).

318 SERVICING AND MAINTENANCE

SCHEDULED SERVICING
3.6L And 5.7L Engines
Your vehicle is equipped with an automatic oil change
indicator system. The oil change indicator system will
remind you that it is time to take your vehicle in for
scheduled maintenance.
Based on engine operation conditions, the oil change
indicator message will illuminate. This means that service
is required for your vehicle. Operating conditions such as
frequent short-trips, trailer tow, extremely hot or cold
ambient temperatures, and E85 fuel usage will influence
when the “Change Oil” or “Oil Change Required” message
is displayed. Severe Operating Conditions can cause the
change oil message to illuminate as early as 3,500 miles
(5,600 km) since last reset. Have your vehicle serviced as
soon as possible, within the next 500 miles (800 km).
The “Oil Change Required” message will be displayed in
the instrument cluster and a single chime will sound,
indicating that an oil change is necessary.
Your authorized dealer will reset the oil change indicator
message after completing the scheduled oil change. If a
scheduled oil change is performed by someone other thanyour authorized dealer, the message can be reset by
referring to “Instrument Cluster Display” in “Getting To
Know Your Instrument Panel” for further information.
NOTE:
Under no circumstances should oil change inter-
vals exceed 10,000 miles (16,000 km), twelve months or 350
hours of engine run time, whichever comes first. The 350
hours of engine run or idle time is generally only a concern
for fleet customers.
Severe Duty All Models
Change Engine Oil at 4,000 miles (6,500 km) or 350 hours of
engine run time if the vehicle is operated in a dusty and
off-road environment, or is operated predominantly at idle
or only very low engine RPM’s. This type of vehicle use is
considered Severe Duty.
Once A Month Or Before A Long Trip:
• Check engine oil level.
• Check windshield washer fluid level.
• Check tire pressure and look for unusual wear or
damage. Rotate tires at the first sign of irregular wear,
even if it occurs before your next scheduled service.
