2009 DODGE VIPER tire pressure

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

only the Black Air Pump Hose 6 and make sure the
Mode Select Knob 4 is in the Air Mode when inflating
such items to avoid injecting sealant into them. The
TIREFIT Sealant is only intended to seal small punc-
tures in the tire tread of a tire on this vehicle.
WARNING!
•Do not attempt to seal a tire on the side of the
vehicle close to traffic. Pull far enough off the road
to avoid the danger of being hit when using the
TIREFIT kit.
•Do not use TIREFIT or drive the vehicle under the
following circumstances:
If the cut or puncture in the tire tread is approxi-
mately 0.24 in (6 mm) or larger.
If the tire has any sidewall damage.
(Continued)
WARNING! (Continued)
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 TIREFIT away from open flame or heat source.
•TIREFIT is not a permanent flat tire repair. Have
the tire inspected and repaired or replaced after
using TIREFIT. Do not exceed 55 mph (90 km/h)
until having the tire repaired or replaced.
•A loose TIREFIT kit thrown forward in a collision
or hard stop could endanger the occupants of the
vehicle. Always stow the TIREFIT kit in the place
provided.

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).
