2017 DODGE VIPER fuel pressure

For example, your vehicle may have a recommended cold
(parked for more than three hours) placard pressure of 30
psi (207 kPa). If the ambient temperature is 68°F (20°C) and
the measured tire pressure is 27 psi (186 kPa), a tempera-
ture drop to 20°F (-7°C) will decrease the tire pressure to
approximately 23 psi (158 kPa). This tire pressure is suffi-
ciently low enough to urn ON the TPM Telltale Light.
Driving the vehicle may cause the tire pressure to rise to
approximately 27 psi (186 kPa), but the TPM Telltale Light
will still be ON. In this situation, the TPM Telltale Light
will turn OFF only after the tires are inflated to the
vehicle’s recommended cold placard pressure value.
CAUTION!
•The TPMS has been optimized for the original
equipment tires and wheels. TPMS pressures and
warning have been established for the tire size
equipped on your vehicle. Undesirable system op-
eration or sensor damage may result when using
replacement equipment that is not of the same size,
type, and/or style. Aftermarket wheels can cause
sensor damage.
(Continued)
CAUTION! (Continued)
•Using aftermarket tire sealants may cause the Tire
Pressure Monitoring System (TPMS) sensor to become
inoperable. After using an aftermarket tire sealant it is
recommended that you take your vehicle to an autho-
rized dealer to have your sensor function checked.
• After inspecting or adjusting the tire pressure always
reinstall the valve stem cap. This will prevent mois-
ture and dirt from entering the valve stem, which
could damage the TPMS sensor.
NOTE:
• The TPMS is not intended to replace normal tire care and
maintenance or to provide warning of a tire failure or
condition.
• The TPMS should not be used as a tire pressure gauge
while adjusting your tire pressure.
• Driving on a significantly under-inflated tire causes the
tire to overheat and can lead to tire failure. Under-
inflation also reduces fuel efficiency and tire tread life,
and may affect the vehicle’s handling and stopping
ability.
232 STARTING AND OPERATING

MAINTENANCE PROCEDURES
The pages that follow contain therequiredmaintenance
services determined by the engineers who designed your
vehicle.
Besides those maintenance items specified in the fixed
“Maintenance Schedule”, there are other components
which may require servicing or replacement in the future.
CAUTION!
• Failure to properly maintain your vehicle or perform
repairs and service when necessary could result in
more costly repairs, damage to other components or
negatively impact vehicle performance. Immediately
have potential malfunctions examined by an autho-
rized dealer or qualified repair center.
• Your vehicle has been built with improved fluids
that protect the performance and durability of your
vehicle and also allow extended maintenance inter-
vals. Do not use chemical flushes in these compo-
nents as the chemicals can damage your engine,
transmission, or air conditioning. Such damage is not
covered by the New Vehicle Limited Warranty. If a
(Continued)
CAUTION! (Continued)
flush is needed because of component malfunction,
use only the specified fluid for the flushing proce-
dure.
Engine Oil
Checking Oil Level
To assure proper engine lubrication, the engine oil must be
maintained at the correct level. Check the oil level at
regular intervals, such as every fuel stop. The best time to
check the oil level is approximately five minutes after a
fully warmed engine is shut off. Do not check oil level
before starting the engine after it has sat overnight. Check-
ing engine oil level when the engine is cold will give you
an incorrect reading.
Checking the oil while the vehicle is on level ground also
will improve the accuracy of the oil level readings. Add oil
only when the level is below the SAFE mark.
CAUTION!
Overfilling or underfilling will cause oil aeration or
loss of oil pressure. This could damage your engine.

CAUTION!
•When installing the power distribution center cover,
it is important to ensure the cover is properly posi-
tioned and fully latched. Failure to do so may allow
water to get into the power distribution center and
possibly result in an electrical system failure.
• When replacing a blown fuse, it is important to use
only a fuse having the correct amperage rating. The
use of a fuse with a rating other than indicated may
result in a dangerous electrical system overload. If a
properly rated fuse continues to blow, it indicates a
problem in the circuit that must be corrected.
VEHICLE STORAGE
We recommend that you follow these guidelines for storing
your vehicle for extended periods.
• Fill the fuel tank. This will prevent water condensation
inside the tank. If you plan to store your vehicle more
than two months, add an anti-oxidant fuel stabilizer to
the fuel tank.
• Change the oil to remove any corrosive combustion
related acids in the crankcase. •
Check that the radiator coolant level of protection is to at
least -20°F (-29°C).
• Make sure that all tires are inflated to the optimum
pressure.
• Wash and wax the vehicle to protect the finish.
• Store the vehicle in a dry, well-ventilated location.
• Move the wiper blades away from the windshield.
• Block the wheels. Do not apply the parking brake.
• Cut blocks of plywood about the same size of the tires.
Cover each block with indoor/outdoor carpeting and
place them between the tires and concrete. This will
prevent tire flat spotting.
• For long-term storage, remove the tires and put the
vehicle up on blocks. Stack the tires on plywood and
cover with a tarp to prevent flat spotting.
• If the vehicle will be subjected to freezing temperatures,
either remove the battery and store it in a dry, well
ventilated area or connect a trickle charger (1.5 Amp)
with automatic shutdown / overcharge protection to the
battery. However, do not leave the trickle charger
hooked up to the battery without being plugged in to a
110 Volt AC outlet, as this will result in further drain on
294 MAINTAINING YOUR VEHICLE

MAINTENANCE SCHEDULES
The Scheduled Maintenance services listed in this manual
must be done at the times or mileages specified to protect
your vehicle warranty and ensure the best vehicle perfor-
mance and reliability. More frequent maintenance may be
needed for vehicles in severe operating conditions, such as
dusty areas and very short trip driving. Inspection and
service should also be done anytime a malfunction is
suspected.
NOTE: Under no circumstances should oil change inter-
vals exceed 6,000 miles (10 000 km) or six months,
whichever comes first.
CAUTION!
Failure to perform the required maintenance items
may result in damage to the vehicle.At Each Stop For Fuel
•
Check the engine oil level about five minutes after a
fully warmed engine is shut off. Checking the oil level
while the vehicle is on level ground will improve the
accuracy of the oil level reading. Add oil only when the
level is at or below the ADD or MIN mark.
• Check the windshield washer solvent, and add if re-
quired.
Once A Month
• 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.
• Inspect the battery, and clean and tighten the terminals
as required.
• Check the fluid levels of the coolant reservoir, brake
master cylinder, power steering, and transmission, and
add as needed.
• Check all lights and all other electrical items for correct
operation.
