2009 DODGE VIPER tires

Rotate the tires “side-to-side” as shown in the diagram.
These effects can be reduced by timely rotation of tires.
The benefits of rotation are especially worthwhile with
aggressive 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 the “Maintenance Schedules” in Section 8 for the
recommended tire rotation frequency for your type of
driving. Remember, more frequent rotation is permissible
if desired. Also, correct for anything causing rapid or
unusual wear prior to performing the tire rotation.
NOTE:Each wheel on your vehicle contains a tire
pressure sensor. The Tire Pressure Monitor System
(TPMS) learns the location of each sensor though system
programming. Although not required, the manufacturer
recommends reprogramming the TPMS after rotating the
tires so that the system can relearn each sensor ’s location.
See your authorized dealer for system reprogramming.
168 STARTING AND OPERATING

TIRE PRESSURE MONITOR SYSTEM (TPMS)
Low Tire Indicator
If tire pressure falls below 23 psi (159 kpa), the Low Tire
Pressure Telltale in the Message Center will illuminate, a
chime will sound, and the words LOW TIRE will flash
slowly in the Liquid Crystal Display (LCD) panel in the
bottom of the speedometer. If tire pressure falls below
18 psi (124 kpa), the Low Tire Pressure Telltale will
illuminate, a chime will sound, and the words “FLAT
TIRE” will flash rapidly in the display. You should obtain
immediate service if the low tire indicator is activated.
NOTE:Each wheel on your vehicle contains a tire
pressure sensor. The TPMS learns the location of each
sensor though system programming. Although not re-
quired, the manufacturer recommends reprogramming
the TPMS after rotating the tires so that the system can
relearn each sensor ’s location. See your authorized dealer
for system reprogramming.
CAUTION!
The Tire Pressure Monitor System (TPMS) has been
optimized for the original equipment tires and
wheels. The TPMS pressures have been established
for the tire size equipped on your vehicle. Undesir-
able operation 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. Do not use aftermarket tire sealants
or balance beads if your vehicle is equipped with the
TPMS, as damage to the sensors may result.
WARNING!
Do not exceed 55 mph (88 km/h) if the LOW Tire
indicator is activated. Vehicle handling and braking
may be reduced. You could have an accident and be
severely or fatally injured.

TPMS Malfunction Warning
Your vehicle has also been equipped with a TPMS
malfunction indicator to indicate when the system is not
operating properly. The TPMS malfunction indicator is
combined with the low tire pressure telltale.
When the system detects a malfunction, the telltale will
flash for approximately one minute and then remain
continuously illuminated. This sequence will continue
upon subsequent vehicle start-ups as long as the mal-
function exists. When the malfunction indicator is illumi-
nated, the system may not be able to detect or signal low
tire pressure as intended.
TPMS malfunctions may occur for a variety of reasons,
including the installation of replacement or alternate tires
or wheels on the vehicle that prevent the TPMS from
functioning properly. Always check the TPMS malfunc-
tion telltale after replacing one or more tires or wheels onyour vehicle to ensure that the replacement or alternate
tires and wheels allow the TPMS to continue to function
properly.
FUEL REQUIREMENTS
8.4L Engine
The 8.4L engine is designed to meet all
emissions regulations and provide excel-
lent fuel economy and performance when
using high-quality premium unleaded
gasoline with an octane rating of 91 or
higher.
Light spark knock at low engine speeds is not harmful to
your engine. However, continued heavy spark knock at
high speeds can cause damage and immediate service is
required.
170 STARTING AND OPERATING

TIREFIT Storage
The TIREFIT kit is located in the trunk.
TIREFIT Usage Precautions
NOTE:
•Replace the TIREFIT Sealant Bottle prior to the expi-
ration date (printed on the bottle label) to assure
optimum operation of the system.
•When the TIREFIT 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
TIREFIT kit.
•You can use the TIREFIT air pump to inflate bicycle
tires. The kit also comes with two needles located in
the Accessory Storage Compartment 8 for inflating
sport balls, rafts, or like inflatable items. However, use

182 WHAT TO DO IN EMERGENCIES

NOTE:The Vehicle Security Alarm System will prevent
the engine from starting.
12. Start the engine in the vehicle with the discharged
battery. If engine does not start in 15 seconds, stop
cranking engine and allow starter to cool down before
cranking again.
13. When removing the booster cables, reverse the above
sequence exactly. Be careful of the moving belts and fans.
WARNING!
Any procedure other than above could result in:
•Personal injury caused by electrolyte squirting out
the battery vent;
•Personal injury or property damage due to battery
explosion;
•Damage to charging system of booster vehicle or
of immobilized vehicle.
FREEING A STUCK VEHICLE
If your vehicle becomes stuck in mud, sand, or snow, it
can often be moved by a rocking motion. Turn your
steering wheel right and left to clear the area around the
front wheels. Then shift back and forth between RE-
VERSE and First gear. Usually the least accelerator pedal
pressure to maintain the rocking motion without spin-
ning the wheels is most effective.
CAUTION!
Racing the engine or spinning the wheels too fast
may lead to transmission/axle overheating and fail-
ure. It can also damage the tires. Do not spin the
wheels above 30 mph (48 km/h).

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 tempera-
tures, 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 the vehicle’s battery. If the vehicle is
not going to be driven in the next three weeks, perform
the battery recharge procedure in the Service Manual.
