2009 DODGE VIPER TPMS

•If the light turns on steady while the engine is running,
safely bring the vehicle to a complete stop as soon as
possible, cycle the ignition key, and then restart the
engine. The light should turn off. However, if the light
remains on steady, see your authorized dealer for
service as soon as possible.
•If the light is flashing when the engine is running,
immediate service is required. If this occurs, you may
experience reduced vehicle performance, an elevated/
rough idle or engine stall, and your vehicle may
require towing.
Low Tire Pressure Telltale / TPMS Malfunction
Indicator
Each tire, including the spare (if provided),
should be checked monthly when cold and in-
flated to the inflation pressure recommended by
the vehicle manufacturer on the vehicle placard
or tire inflation pressure label. (If your vehicle has tires ofa different size than the size indicated on the vehicle
placard or tire inflation pressure label, you should deter-
mine the proper tire inflation pressure for those tires.)
As an added safety feature, your vehicle has been
equipped with a Tire Pressure Monitoring System
(TPMS) that illuminates a low tire pressure telltale when
one or more of your tires is significantly under-inflated.
Accordingly, when the low tire pressure telltale illumi-
nates, you should stop and check your tires as soon as
possible and inflate them to the proper 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.
Please note that the TPMS is not a substitute for proper
tire maintenance, and it is the driver ’s responsibility to
maintain correct tire pressure, even if under-inflation has
not reached the level to trigger illumination of the TPMS
low tire pressure telltale.

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.
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.

132 STARTING AND OPERATING

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.

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.

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.
