2009 DODGE VIPER tires

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

•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

DRIVING ON SLIPPERY SURFACES
Acceleration
WARNING!
Rapid acceleration on slippery surfaces is dangerous.
You could lose control of the vehicle and possibly
have an accident. Accelerate slowly and carefully
whenever there is likely to be poor traction (ice,
snow, wet, mud, loose sand, etc.).
Traction
When driving on wet or slushy roads, it is possible for a
wedge of water to build up between the tire and road
surface. This is hydroplaning and may cause partial or
complete loss of vehicle control and stopping ability. To
reduce this possibility, the following precautions should
be observed:1. Slow down during rainstorms or when roads are
slushy.
2. Slow down if road has standing water or puddles.
CAUTION!
Driving your vehicle through deep puddles at speeds
over 5 mph (8 km/h), may cause water to be ingested
into the engine. This can cause severe engine dam-
age.
3. Replace tires when tread wear indicators first become
visible.
4. Keep tires properly inflated.
5. Maintain enough distance between your vehicle and
the vehicle in front to avoid a collision in a sudden stop.

WARNING! (Continued)
•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.
•Anti-lock system (ABS) cannot prevent the natural
laws of physics from acting on the vehicle, nor can
it increase braking or steering efficiency beyond
that afforded by the condition of the vehicle
brakes and tires or the traction afforded.
•The ABS cannot prevent accidents, including
those resulting from excessive speed in turns,
following another vehicle too closely, or hydro-
planing. Only a safe, attentive, and skillful driver
can prevent accidents.
(Continued)
WARNING! (Continued)
•The capabilities of an ABS equipped vehicle must
never be exploited in a reckless or dangerous
manner, which could jeopardize the user’s safety
or the safety of others.
All vehicle wheels and tires must be the same size and
type as the original equipment and the tires must be
properly inflated to produce accurate signals for the
computer.
WARNING!
Significant over- or under-inflation of tires, or mix-
ing sizes of front or rear tires or wheels on the vehicle
can lead to loss of braking effectiveness.
150 STARTING AND OPERATING

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.
152 STARTING AND OPERATING

Tire Identification Number (TIN)
The TIN may be found on one or both sides of the tire,
however, the date code may only be on one side. Tires with
white sidewalls will have the full TIN, including the date code,located on the white sidewall side of the tire. Look for the TIN
on the outboard side of black sidewall tires as mounted on the
vehicle. If the TIN is not found on the outboard side, then you
will find it on the inboard side of the tire.
EXAMPLE:
DOT MA L9 ABCD 0301
DOT= Department of Transportation
— This symbol certifies that the tire is in compliance with the U.S. Department of Transportation tire
safety standards and is approved for highway use
MA= Code representing the tire manufacturing location (two digits)
L9= Code representing the tire size (two digits)
ABCD= Code used by the tire manufacturer (one to four digits)
03= Number representing the week in which the tire was manufactured (two digits)
—03 means the 3rd week.
01= Number representing the year in which the tire was manufactured (two digits)
—01 means the year 2001
— Prior to July 2000, tire manufacturers were only required to have one number to represent the year
in which the tire was manufactured. Example: 031 could represent the 3rd week of 1981 or 1991
