DODGE VIPER 2005 ZB / 2.G Owners Manual

In the event power assist is lost for any reason (for
example, repeated brake applications with the engine
off), the brakes will still function. The effort required to
brake the vehicle will be much greater than that required
with the power system operating.
If either the front or rear hydraulic system loses normal
capability, the remaining system will still function with
some loss of overall braking effectiveness. This will be
evident by increased pedal travel during application,
greater pedal force required to slow or stop, and activa-
tion of the Brake Warning Lamp during brake use.
NOTE:Your Viper has a very high performance braking
system. The brake pads are a semi-metallic compound
which has been selected for superior fade resistance and
consistent operation. A compromise is that under some
weather and operating conditions, the brakes may squeal
slightly during light brake applications.Brake Pad Break-In
The brakes on your new Viper do not require a long
break-in period, but avoid repeated hard brake applica-
tions from high speeds during initial break-in. Also avoid
severe brake loading such as may be encountered when
descending long mountain grades.
POWER STEERING
The power assisted steering system of your vehicle
provides mechanical steering capability in the event
power assist is lost.
If for some reason the hydraulic pressure is interrupted,
it will still be possible to steer your vehicle. Under these
conditions you will observe a substantial increase in
steering effort.

TIRE SAFETY INFORMATION
Tire Markings
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 designation. Ex-
ample: 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 begins with the tire diameter molded
into the sidewall. Example: 31x10.5 R15 LT.

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
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.(2 digits)
L9= Code representing the tire size.(2 digits)
ABCD= Code used by tire manufacturer.(1 to 4 digits)
03= Number representing the week in which the tire was manufactured.(2 digits)
—03 means the 3rd week.
01= Number representing the year in which the tire was manufactured.(2 digits)
—01 means the year 2001.
—Prior to July 2000, tire manufacturers were only required to have 1 number to represent the year in
which the tire was manufactured. Example: 031 could represent the 3rd week of 1981 or 1991.

Tire Placard Location
NOTE:The proper cold tire inflation pressure for pas-
senger cars is listed on either the face of the driver’s door
or the driver’s side“B”pillar. For vehicles other than
passenger cars, the cold tire inflation pressures are listed
on either the“B”pillar, the Certification Label or in the
Tire Inflation Pressures brochure in the glove compart-
ment.

Tire and Loading Information Placard
This placard tells you important information about the,
1) number of people that can be carried in the vehicle
2) the total weight your vehicle can carry
3) the tire size designed for your vehicle4) the cold tire inflation pressures for the front, rear
and spare tires.
Loading
The vehicle maximum load on the tire must not exceed
the load carrying capacity of the tire on your vehicle. You
will not exceed the tire’s load carrying capacity if you
adhere to the loading conditions, tire size and cold tire
inflation pressures specified on the Tire and Loading
Information placard and the Vehicle Loading section of
this manual.
NOTE:Under a maximum loaded vehicle condition,
gross axle weight ratings (GAWR’s) for the front and rear
axles must not be exceeded. For further information on
GAWR’s, vehicle loading and trailer towing, see the
Vehicle Loading section of this manual.
To determine the maximum loading conditions of your
vehicle, locate the statement“The combined weight of
occupants and cargo should never exceed XXX kg or XXX

lbs.”on the Tire and Loading Information placard. The
combined weight of occupants, cargo/luggage and
trailer tongue weight (if applicable) should never exceed
the weight referenced here.
Steps for Determining Correct Load Limit
1. Locate the statement“The combined weight of occu-
pants and cargo should never exceed XXX pounds”on
your vehicle’s placard.
2. Determine the combined weight of the driver and
passengers that will be riding in your vehicle.
3. Subtract the combined weight of the driver and pas-
sengers from XXX kilograms or XXX pounds.
4. The resulting figure equals the available amount of
cargo and luggage load capacity. For example, if“XXX”
amount equals 1400 lbs. and there will be five 150 lb.
passengers in your vehicle, the amount of available cargo
and luggage load capacity is 650 lb. (since 5 x 150 = 750,
and 1400–750 = 650 lb.)5. Determine the combined weight of luggage and cargo
being loaded on the vehicle. That weight may not safely
exceed the available cargo and luggage load capacity
calculated in step 4.
6. If your vehicle will be towing a trailer, load from your
trailer will be transferred to your vehicle. Consult this
manual to determine how this reduces the available
cargo and luggage load capacity of your vehicle.
NOTE:The following table shows examples on how to
calculate total load, cargo/luggage and towing capacities
of your vehicle with varying seating configurations and
number and size of occupants. This table is for illustra-
tion purposes only and may not be accurate for the
seating and load carry capacity of your vehicle.
NOTE:For the following example the combined weight
of occupants and cargo should never exceed 865 lbs. (392
Kg).

WARNING!
Overloading of your tires is dangerous. Overloading
can cause tire failure, affect vehicle handling, and
increase your stopping distance. Use tires of the
recommended load capacity for your vehicle. Never
overload them.
TIRES—GENERAL INFORMATION
Tire Pressure
Proper tire inflation pressure is essential to the safe and
satisfactory operation of your vehicle. Three primary
areas are affected by improper tire pressure:1. Safety—
WARNING!
Improperly inflated tires are dangerous and can cause
accidents.
•Under inflation increases tire flexing and can result in
tire failure.
•Over inflation reduces a tire’s ability to cushion shock.
Objects on the road and chuck holes can cause damage
that results in tire failure.
•Unequal tire pressures can cause steering problems.
You could lose control of your vehicle.
•Over inflated or under inflated tires can affect vehicle
handling and can fail suddenly, resulting in loss of
vehicle control.
•Unequal tire pressures from one side of the vehicle to
the other can cause the vehicle to drift to the right or left.
Always drive with each tire inflated to the recommended
cold tire inflation pressure.
