2004 DODGE VIPER run flat

2.All occupants should wear their lap and shoulder
belts properly.
3.The driver and passenger seats should be moved
back as far as practical to allow the airbags room to
inflate. Additionally, the pedals are power adjustable,
so the driver seat can be moved back and the pedals
moved closer as needed so the driver can be as far from
the airbag as possible. (See section on Power Adjust-
able Pedals for operation.)
4.You should read the instructions provided with your
child safety or booster seat to make sure that you are
using it properly.
The airbag system consists of the following:
²Airbag control module and internal crash sensor
²AIRBAG Readiness Light
²Driver and Passenger Airbag/inflator Units
²Passenger Side Airbag On/Off Switch
²Passenger Airbag Off Indicator Light
²Unique Steering Wheel and Column
²Unique Instrument Panel
²Interconnecting Wiring
²Knee Impact Bolster
How The Airbag System Works
²
A crash sensor in the occupant compartment deter-
mines if a frontal impact is severe enough to require
the airbag. The sensor will not detect side, roll over, or
rear impacts. The crash sensor is connected to the
diagnostic unit and to the airbag/inflator unit.
²The Diagnostic Unit monitors the readiness of the
electronic parts of the system whenever the ignition
switch is in the START or RUN position. These include
40 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

BRAKE SYSTEM
The Anti-Lock Brake System (ABS) is designed to aid the
driver in maintaining vehicle control under adverse
braking conditions. The system operates with a separate
computer to modulate hydraulic pressure to prevent
wheel lock-up and help avoid skidding on slippery
surfaces.
All vehicle wheels and tires must be the same size and
type as the original equipment wheels and tires must be
properly inflated to produce accurate signals for the
computer.
WARNING!
Significant over or under inflation of tires, or mixing
sizes of front or rear tires or wheels on the vehicle
can lead to loss of braking effectiveness.
The Anti-Lock Brake System conducts a low-speed self-
test at about 12 mph (20 km/h). If you have your foot
lightly on the brake while this test is occurring, you may
feel slight pedal movement. The movement can be more
apparent on ice and snow. This is normal.
The Anti-Lock Brake System pump motor runs during
the self-test at 12 mph (20 km/h) and during an ABS stop.
The pump motor makes a low humming noise during
operation, which is normal.
WARNING!
Pumping of the Anti-Lock Brakes will diminish
their effectiveness and may lead to an accident.
Pumping makes the stopping distance longer. Just
press firmly on your brake pedal when you need to
slow down or stop.
104 STARTING AND OPERATING

Improper alignment will not cause vehicle vibration.
Vibration may be a result of tire and wheel out-of-
balance. Proper balancing will reduce vibration and
avoid tire cupping and spotty wear.
Low Tire Pressure (LTP) System
Low Tire Indicator
The Low Tire indicator in the Liquid Crystal Display
(LCD) of the instrument cluster will flash slowly and a
single chime will sound to warn if tire pressure falls
below 20 psi (138 kpa). The indicator will flash more
rapidly and a continuous tone will sound to warn if tire
pressure falls below 14 psi (97 kpa). Seek repair as soon as
possible.
If the indicator stays on and one chime will sound, a
system failure has occurred. See your dealer for service.Although the tires are designed with a ªrun flatº feature
that allows the vehicle to be driven about 50 miles (80
km) at 55 m.p.h. (88 kph), immediate service should be
obtained if the Low Tire indicator is activated.
WARNING!
Do not exceed 55 m.p.h. (88 k.p.h.) if the LOW Tire
indicator in the instrument cluster is illuminated.
Vehicle handling and braking may be reduced. You
could have an accident and be severely or fatally
injured.
NOTE:The ªrun flatº feature eliminates the need for a
spare tire and jack. This vehicle is not equipped with
either a spare tire or jack.
124 STARTING AND OPERATING

Check the battery every 4 to 6 weeks to ensure that the
voltage is above 12.40. Voltage will drop more rapidly
in hot temperatures. If battery voltage drops below
12.40, follow the battery recharge procedure in the
Service Manual.
²Check that the radiator coolant level of protection is to
at least -20ÉF (-29ÉC).
²Block the wheels. Do not apply the Parking Brake.
²Make sure that all tires are inflated to the optimum
pressure, (29 PSI).
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.
²Move the wiper blades away from the windshield.
NOTE:To help prevent the battery from discharging
during shorter periods of inactivity, perform the follow-
ing:
1. Make sure that the trunk, hood, doors, windows and
convertible top are completely closed.
2. Make sure that remote transmitter is operating and
that the battery is good.
3. Make sure that the hood, trunk and door switches are
in adjustment. Perform the quick system check which
follows.
Use the remote transmitter to set the alarm. If the alarm
SET light comes on and flashes, the system is operating
properly. If not, there is a problem with a switch or the
system. See your dealer for service.
