Recommended Shift Speeds
To use your manual transmission for fuel economy it
should be upshifted as listed below. Shift at the vehicle
speeds listed for acceleration. Earlier upshifts during
cruise conditions (relatively steady speeds) will result in
increased fuel economy, and may be used as indicated.
MANUAL TRANSMISSION
RECOMMENDED SHIFT SPEEDS
1-2 2-3 3-4 4-5 5-6
MPH 15 25 40 45 50
(km/h) (24) (40) (64) (72) (80)
Higher upshift speeds may be used to obtain a desired
acceleration rate.
Skip Shift Light
There are times when you must shift directly from First to
Fourth gear instead of from First to Second. An amber
(LED) arrow on the instrument cluster will light up
during these times. This is to help you get the best
possible fuel economy.
The shift arrow will light up when engine coolant is
higher than 106ÉF (41ÉC), vehicle speed is greater than 12
MPH and less than 20 MPH, engine speed is less than
1322 RPM, you are in 1st gear and you are at 1/4 throttle
or less.
When the arrow is lit, the shift mechanism will only
allow shifts from First to Fourth gears. After you shift to
Fourth gear, you can press the clutch in and shift to
another forward gear.
Downshifting - Proper downshifting will improve fuel
economy and prolong engine life.

To maintain a safe speed and prolong brake life, down-
shift to maintain a safe speed when descending a steep
grade.
WARNING!
Skipping more than one gear while downshifting,
could cause you to lose control of your vehicle. You
could have an accident.
CAUTION!
If you skip more than one gear while downshifting
or downshift at too high an engine speed, you could
damage the engine, transmission, or clutch.
PARKING BRAKE
When you apply the parking brake with the ignition ON,
the brake system warning light in the instrument cluster
will come on.
NOTE:This light shows only that the parking brake is
on. It does not show the degree of brake application.
102 STARTING AND OPERATING
Page 103 of 236
Before leaving the vehicle, make sure you fully apply the
parking brake. Place the transmission in REVERSE. Fail-
ure to do so may cause the vehicle to roll and cause
damage or injury.
As an added precaution, turn the front wheels toward the
curb on a downhill grade and away from the curb on an
uphill grade.
Always apply the parking brake whenever you are not in
the vehicle.WARNING!
Leaving children in a vehicle unattended is danger-
ous for a number of reasons. A child or others could
be injured. Children should be warned not to touch
the parking brake release lever or the gear selection
lever as doing so may move the vehicle. Don't leave
the keys in the ignition. Be sure the parking brake is
fully disengaged before driving: failure to do so can
lead to brake failure, and an accident.

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
Page 105 of 236
CAUTION!
The Anti-Lock Brake System is subject to possible
detrimental effects of electronic interference caused
by improperly installed after-market radios or tele-
phones.
WARNING!
²Anti-lock system (ABS) cannot prevent the natu-
ral laws of physics from acting on the vehicle, nor
can it increase braking or steering efficiency be-
yond that afforded by the condition of the vehicle
brakes and tires or the traction afforded.
²The 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.
²The 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.

NOTE:During severe braking conditions, a pulsing
sensation may occur and a clicking noise will be heard.
This is normal, indicating that the Anti-Lock Brake
System is functioning.WARNING!
To use your brakes and accelerator more safely, follow
these tips:
²Do not ªrideº 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.
²When 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.
²Do 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.
²After 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 ac-
tion while driving at very slow speeds.
106 STARTING AND OPERATING
Page 107 of 236
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:
²P(Passenger)-Metric tire sizing is based on U.S. design
standards. P-Metric tires have the letter ªPº molded
into the sidewall preceding the size designation. Ex-
ample: P215/65R15 95H.
²European 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 letter9P9is absent from this tire
size designation. Example: 215/65R15 96H
²LT(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 ªLTº that are molded into the sidewall preced-
ing the size designation. Example: LT235/85R16.
²Temporary Spare tires are high pressure compact
spares designed for temporary emergency use only.
Tires designed to this standard have the letter ªTº
molded into the sidewall preceding the size designa-
tion. Example: T145/80D18 103M.
²High 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.
