2009 DODGE VIPER brakes

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.WARNING!
If the ABS and/or Brake Warning Lights illuminate,
please seek service immediately! Your vehicle will
have diminished braking capability and control if
ABS and/or service brake systems are not working
properly. Have your brake system serviced immedi-
ately.
Malfunction Indicator Light (MIL)
The Malfunction Indicator Light (MIL) is part
of an onboard diagnostic system called OBD.
The OBD system monitors engine control sys-
tems. The light will turn on when the key is in
the ON/RUN position before engine start. If the light
does not come on when turning the key from OFF/LOCK
to ON/RUN, have the condition checked promptly.

Brake Warning Light
The red Brake System Warning Light turns on
when the ignition is first turned on. It should
stay on briefly as a bulb check. If the light does not turn
on during starting, have it repaired promptly. If the light
remains on following the bulb check, it may be an
indication that the parking brake is not released. If the
light remains on when the parking brake is released, it
indicates a possible hydraulic brake system malfunction.
In this case, immediate repair is necessary and continued
operation of the vehicle in this condition is dangerous.
NOTE:The light will turn on when the ignition switch
is in the ON/RUN position and the parking brake is
applied. This light shows only that the parking brake is
applied. It does not show the degree of brake application.WARNING!
Driving a vehicle with the brake light on is danger-
ous. Part of the brake system has failed. It will take
longer to stop the vehicle. You could have an acci-
dent. Have the brakes checked immediately.
Electronic Throttle Control (ETC) Light
This light will turn on briefly as a bulb check
when turning on the ignition switch. It will also
turn on while the engine is running to warn of
a problem with the Electronic Throttle Control
(ETC) system.
•If the light fails to turn on during the bulb check, see
you authorized dealer for service.

CAUTION! (Continued)
•Driving through standing water may cause dam-
age to your vehicle’s drivetrain components. Al-
ways inspect your vehicle’s fluids (i.e., engine oil,
transmission/transaxle, axle, etc.) for signs of con-
tamination (i.e., fluid that is milky or foamy in
appearance) after driving through standing water.
Do not continue to operate the vehicle if any fluid
appears contaminated, as this may result in further
damage. Such damage is not covered by the New
Vehicle Limited Warranty.
•Getting water inside your vehicle’s engine can
cause it to lock up and stall out, and cause serious
internal damage to the engine. Such damage is not
covered by the New Vehicle Limited Warranty.
WARNING!
•Driving through standing water limits your vehi-
cle’s traction capabilities. Do not exceed 5 mph
(8 km/h) when driving through standing water.
•Driving through standing water limits your vehi-
cle’s braking capabilities, which increases stop-
ping distances. Therefore, after driving through
standing water, drive slowly and lightly press on
the brake pedal several times to dry the brakes.
•Getting water inside your vehicle’s engine can
cause it to lock up and stall out, and leave you
stranded.
•Failure to follow these warnings may result in
injuries that are serious or fatal to you, your
passengers, and others around you.

BRAKE SYSTEM
Your vehicle is equipped with dual hydraulic
brake systems. If either of the two hydraulic
systems loses normal capability, the remaining
system will still function. However, there will
be some loss of overall braking effectiveness. You may
notice increased pedal travel during application, greater
pedal force required to slow or stop, and potential
activation of the Brake System Warning Light.
In the event power assist is lost for any reason (i.e.,
repeated brake applications with the engine off) the
brakes will still function. However, the effort required to
brake the vehicle will be much greater than that required
with the power system operating.
Brake Pad Break-In
NOTE:Your vehicle is equipped with a high perfor-
mance braking system. The brake pads are a semi-
metallic compound, which offer superior fade resistance
for consistent operation. A compromise to using this type
of brake pad is that the brakes may squeal slightly under
certain weather and operating conditions (.i.e., during
light brake applications).
The brakes on your new vehicle do not require a long
break-in period. However, you should avoid repeated
hard brake applications from high speeds during initial
break-in. In addition, you should avoid severe brake
loading, such as may be encountered when descending
long mountain grades.

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

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

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.

•Keep the front of the radiator clean. If your vehicle is
equipped with air conditioning, keep the front of the
condenser clean.
•Do not change the thermostat for Summer or Winter
operation. If replacement is ever necessary, install
ONLY the correct type thermostat. Other designs may
result in unsatisfactory cooling performance, poor gas
mileage, and increased emissions.
Brake System
In order to assure brake system performance, all brake
system components should be inspected periodically.
Refer to the “Maintenance Schedules” in Section 8 of this
manual for the proper maintenance intervals.
WARNING!
Riding the brakes can lead to brake failure and
possibly an accident. Driving with your foot resting
or riding on the brake pedal can result in abnormally
high brake temperatures, excessive lining wear, and
possible brake damage. You would not have your full
braking capacity in an emergency.
Master Cylinder - Brake Fluid Level Check
Check the fluid level in the master cylinder immediately
if the brake system warning light indicates system fail-
ure.
Check the fluid level in the master cylinder when per-
forming underhood services.
