2009 DODGE VIPER tire pressure

Periodic Safety Checks You Should Make Outside
The Vehicle
Tires
Examine tires for excessive tread wear or uneven wear
patterns. Check for stones, nails, glass, or other objects
lodged in the tread. Inspect the tread and side wall for
cuts and cracks. Check the wheel nuts for tightness.
Check the tires for proper pressure.
Lights
Have someone observe the operation of exterior lights
while you work the controls. Check Turn Signal and High
Beam Indicator Lights on the instrument panel.
Door Latches
Check for positive closing, latching, and locking.
Fluid Leaks
Check the area under the vehicle after overnight parking
for fuel, water, oil, or other fluid leaks. Also, if gasoline
fumes are present, the cause should be corrected
immediately.
62 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

•The word “DECK” will flash in the display if the
trunk/liftgate is open.
•The words “LOW TIRE” will flash slowly in the
display and a chime will sound if the tire pressure is
low.
•The words “FLAT TIRE” will flash rapidly in the
display and a chime will sound if critically low tire
pressure is detected.
Message Center
When the appropriate conditions ex-
ist, the Message Center displays the
following indicators and warnings:
High Beam Light
This light will turn on when the high beam
headlights are on. Pull the Multifunction Lever on
the left side of the steering column toward you to switch
the headlights from low beam to high beam. Pull the
lever a second time to switch the headlights back to low
beam.
Front Fog Light Indicator
This light will turn on when the front fog lights are
on.
Anti-Lock Brake (ABS) Warning Light
The amber Anti-Lock Brake Warning Light will
turn on and stay on briefly as a bulb check
when the ignition is first turned on. If the light
does not turn on during starting, see your
authorized dealer for service.

•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.

Safe Operating Tips
WARNING!
To use your brakes and accelerator more safely,
follow these tips:
•Do not “ride” the brakes by resting your foot on
the pedal. This could overheat the brakes and
result in unpredictable braking action, longer
stopping distances, or brake damage.
•When descending mountains or hills, repeated
braking can cause brake fade with loss of braking
control. Avoid repeated heavy braking by down-
shifting the transmission whenever possible.
(Continued)
WARNING! (Continued)
•Do not drive too fast for road conditions, espe-
cially when roads are wet or slushy. A wedge of
water can build up between the tire tread and the
road. This hydroplaning action can cause loss of
traction, braking ability, and control.
•After going through deep water or a car wash,
brakes may become wet, resulting in decreased
performance and unpredictable braking action.
Dry the brakes by gentle, intermittent pedal action
while driving at very slow speeds.
Anti-Lock 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.
148 STARTING AND OPERATING

Anti-Lock Brake Warning Light
The amber Anti-Lock Brake Warning Light will
turn on and stay on briefly as a bulb check
when the ignition is first turned on. If the light
does not turn on during starting, have it re-
paired promptly.
This light also illuminates at vehicle start-up to indicate
that the ABS self-check is in process. If the light remains
on after start-up, or turns on and remains on at road
speeds, it may indicate a system malfunction or that the
system is inoperative. In this case, the system reverts to
standard non-anti-lock brakes. If this occurs, safely bring
the vehicle to a complete stop as soon as possible and
cycle the ignition key to attempt to reset the ABS. If the
light remains on, see your authorized dealer immediately
to have the system serviced. Furthermore, if the red
BRAKE Warning Light and the amber ABS Warning
Light are on, and the parking brake is fully released, see
your authorized dealer immediately.

NOTE:
•P (Passenger) - Metric tire sizing is based on U.S.
design standards. P-Metric tires have the letter “P”
molded into the sidewall preceding the size designa-
tion. Example: P215/65R15 95H.
•European-Metric tire sizing is based on European
design standards. Tires designed to this standard have
the tire size molded into the sidewall beginning with
the section width. The letterPis absent from this tire
size designation. Example: 215/65R15 96H.
•LT (Light Truck) - Metric tire sizing is based on U.S.
design standards. The size designation for LT-Metric
tires is the same as for P-Metric tires except for the
letters “LT” that are molded into the sidewall preced-
ing the size designation. Example: LT235/85R16.
•Temporary spare tires are high-pressure compact
spares designed for temporary emergency use only.
Tires designed to this standard have the letter “T”
molded into the sidewall preceding the size designa-
tion. Example: T145/80D18 103M.
•High flotation tire sizing is based on U.S. design
standards and it begins with the tire diameter molded
into the sidewall. Example: 31x10.5 R15 LT.
