2008 DODGE VIPER tire pressure

TIRE PRESSURE MONITOR SYSTEM (TPMS)
Low Tire Indicator
If tire pressure falls below 20 psi (138 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 14
psi (97 kpa), the Low Tire Pressure Telltale will illumi-
nate, 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.
166 STARTING AND OPERATING

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 continueupon 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 on
your vehicle to ensure that the replacement or alternate
tires and wheels allow the TPMS to continue to function
properly. (See page 101 for more information.)

²You can use the TIREFIT air pump to inflate bicycle
tires. The kit also comes with two needles for inflating
sport balls, rafts, or like inflatable items. However, use
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 punctures in the tire tread of a tire on this
vehicle.WARNING!
²Do 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.
²Do not use TIREFIT or drive the vehicle under the following
circumstances:
þ If the cut or puncture in the tire tread is approximately 0.24 in. (6
mm) or larger.
þ If the tire has any sidewall damage.
þ If the tire has any damage from driving with extremely low tire
pressure.
þ If the tire has any damage from driving on a flat tire.
þ If the wheel has any damage.
þ If you are unsure of the condition of the tire or the wheel.
²Keep TIREFIT away from open flame or heat source.
²TIREFIT 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.
²A 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.
Failure to follow these warnings can result in injuries that are
serious or fatal to you, your passengers, and others around you.

WARNING!
²Take care not to allow the contents of TIREFIT to
come in contact with hair, eyes, or clothing. TIRE-
FIT is harmful if inhaled, swallowed, or absorbed
through the skin: It causes skin, eye, and respira-
tory irritation. Flush immediately with plenty of
water if there is any contact with eyes or skin.
Change clothing as soon as possible, if there is any
contact with clothing.
²TIREFIT Sealant solution contains latex. In case of
allergic reaction or rash, consult a physician imme-
diately. Keep TIREFIT out of reach of children. If
swallowed, rinse mouth immediately with plenty
of water and drink plenty of water. Do not induce
vomiting! Consult a physician immediately.

²Connect the Power Plug (5) to a different power
outlet in your vehicle or another vehicle, if available.
Make sure the engine is running before turning on
the TIREFIT kit.
²The Sealant Bottle (1) may be empty due to previous
use. Call for assistance.
(D) After Injecting TIREFIT Sealant:
1. Allow the air pump to inflate the tire to the pressure
indicated on the tire pressure label on the driver-side
latch pillar. Check the pressure in the tire by looking at
the Pressure Gauge (2).
²If the tire inflates to at least 26 psi (1.8 bar) within 15
minutes, proceed to Step 2 of this procedure.
²If tire fails to inflate to 26 psi (1.8 bar) within 15
minutes, perform the procedure steps described

Cooling System
WARNING!
²When working near the radiator cooling fans,
disconnect each fan motor lead or turn the ignition
switch to the OFF position. The fans are tempera-
ture controlled and can start any time the ignition
switch is in the ON position.
²You or others can be badly burned by hot coolant
or steam from your radiator. If you see or hear
steam coming from under the hood, don't open the
hood until the radiator has had time to cool. Never
try to open a cooling system pressure cap when the
radiator is hot.
Coolant Checks
Check engine coolant (antifreeze) protection every 12
months (before the onset of freezing weather, where
applicable). If coolant is dirty or rusty in appearance, the
system should be drained, flushed, and refilled with
fresh coolant. Check the front of the A/C condenser/
radiator for any accumulation of bugs, leaves, etc. If dirty,
clean by gently spraying water from a garden hose
vertically down the face of the condenser/radiator.
Check the coolant recovery bottle tubing for brittle rub-
ber, cracking, tears, cuts, and tightness of the connection
at the bottle and radiator. Inspect the entire system for
leaks.
With the engine at normal operating temperature (but
not running), check the cooling system pressure cap for
proper vacuum sealing by draining a small amount of
coolant from the radiator drain cock. If the cap is sealing
properly, the engine coolant (antifreeze) will begin to

VEHICLE STORAGE
We recommend that you follow these guidelines for
storing your vehicle for extended periods.
²Fill the fuel tank. This will prevent water condensation
inside the tank. If you plan to store your vehicle more
than 2 months, add an anti-oxidant fuel stabilizer to
the fuel tank.
²Change the oil to remove any corrosive combustion
related acids in the crankcase.
²Check that the radiator coolant level of protection is to
at least -20ÉF (-29ÉC).
²Make sure that all tires are inflated to the optimum
pressure. (See page 158 for more information.)
²Wash and wax the vehicle to protect the finish.
²Store the vehicle in a dry, well-ventilated location.
²Move the wiper blades away from the windshield.
²Block the wheels. Do not apply the Parking Brake.
²Cut 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.
²For 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.
²If 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 protec-
tion 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 3 weeks, perform the
battery recharge procedure in the Service Manual.
