ADJUSTABLE PEDALS
Adjustable Pedals
• Push the switch located on the trim panelbelow the steering column forward to move
the brake, accelerator and clutch pedals
away from the driver and push the switch
rearward to move the pedals closer to the
driver.
WARNING!
Do not adjust the pedals while the vehicle is moving. You could lose control and have
an accident. Always adjust the pedals while the vehicle is parked.
CAUTION!
Do not place any article under the adjustable pedals or impede its ability to move, as
it may cause damage to the pedal controls. Pedal travel may become limited if
movement is stopped by an obstruction in the adjustable pedal's path.
Adjustable Foot Rest
• Using a 13 mm socket wrench, loosen the
nut on the pedal.
• Slide the pedal either forward or backward and rotate it upward or downward as
desired.
• Tighten the nut, being careful not to over tighten it.

GETTING STARTED
OVERVIEW
• The Viper ACR is the literal fusion of Street and Racing Technology. It takes the aweinspiring performance capabilities of the Dodge Viper SRT10 to the next level.
• The Viper ACR is not certified as a race car and it is not equipped with a racing safety cage, racing restraints or other racing safety equipment.
• Throughout this manual there are notes of WARNING and CAUTION. Review each of them before driving this car.
WARNING!
It is recommended that all customers comple te a high-performance driving school
prior to operating this vehicle. Speeds at the handling limits of this car are much
higher than with other sports cars. Competitive driving and track outings can cause
serious injury or death.
• Drive safely.

Track Extension
• A splitter track extension is included in thetrunk of every Viper ACR. The track extension
is mounted in the same location as the
center rub strip. The on-track aerodynamic
balance was optimized with the track
extension in place.
• To install the track extension, remove the eight (8) screws of the center rub strip and
install the extension in the same mounting
locations.
• Tighten fasteners to 70 in-lbs (7.9 N·m).
CAUTION!
The track extension should only be used during closed circuit track events. The track
extension can cause prem ature damage to your vehicle if used on public roads.
Rear Wing
• The ACR rear wing generates most of the
car’s aerodynamic downforce.
• The wing is a powerful element that will affect the handling of the car at speeds
greater than 50 mph. Extreme caution
should be given to any modifications to the
factory settings.
WARNING!
Do not operate the vehicle with the rear wing removed. The aerodynamic balance of
this setup is unstable and can cause the loss of control.
• Regularly inspect the wing panel and attachment points for damage or looseness.
• The Viper ACR on-track aerodynamics have been tuned and balanced for the vehicle with the track extension installed.

CAUTION!
Do not come to a complete stop when the system is hot and leave your foot on the
pedal. Pad material will immediately transfer to the rotor causing a vibration during
future use.
• After the final stop, drive as much as possible without using the brakes to cool off the system. Ideally, the brakes should be allowed to cool to ambient temperature
before using them again.
• After the first break in cycle, the brakes will still not be operating at optimum capacity. A second or third heat cycle is typically necessary before the brakes start
to work optimally. This will occur during everyday use.
Care and Maintenance
• Your brake calipers have a painted finish. Immedi ately clean off any spilled brake
fluid, wiping it off with a soft, clean terry-cloth towel.
• Do not use any harsh chemicals when cleaning your calipers. Wash your calipers with soap and rinse with water.
• Do not use any harsh chemicals when cleaning your rotor hats (the anodized center part of the rotor assembly). Wash your rotor hats with soap and rinse with water.
• Breaking-in rotors and pads is critical to the optimum performance of your new brakes. When breaking-in new parts, you are not only heat-cycling the pads, you are
also depositing a layer of pad material onto the rotor face. If not broken-in properly, an
uneven layer of pad material will be deposited onto the rotor, causing vibration.
• If you experience brake pedal pulsation, steering vibration, or repeatable brake noise, perform the break-in procedure again as soon as possible. This will re-condition the
rotor surface and remove irregular brake pad deposits. If concerns continue, please
visit y our local dealer fo r further diagnosis.
PILOT SPORT CUP TIRES
• Your Viper ACR comes equipped with Michelin Pilot Sport Cup competition oriented
tires that are DOT approved for street use. The Pilot Sport Cup tire uses a special tread
and compound which provides considerably more dry grip than normal street tires.
• Due to the special tread and compound of your Pilot Sport Cup Tires, the minimum tread depth can be reached earlier dependin g on your driving style, resulting in
reduced tire life. The special Pilot S port Cup tread and compound may lead to
performance degradation in cold climates, heavy rain or in conditions with standing
water.
WARNING!
Use extreme caution and drive slowly in wet situations to reduce the risk of
hydroplaning. Avoid driving in any conditions of heavy rain or standing water. These
conditions can cause loss of control or accident.
PERFORMANCE/ACR
36
WARNING!
The Pilot Sport Cup tires were NOT intended to be driven on snow or ice. The Pilot
Sport Cup is a summer season tire and has diminished capability on cold road
surfaces (below 50°F). DO NOT OPERATE THE VEHICLE DURING THESE CONDITIONS.
Snow, ice and cold road surfaces can cause a loss of control or accident.
ADJUSTABLE DAMPERS
• The Viper ACR suspension includes a set of adjustable coil-over racing dampers built
by KW Suspensions. These dampers hav e been tuned by SRT handling engineers to
provide the maximum handling performance without sacrificing reasonable road
manners.
• The two-way adjustable dampers inc lude adjustments for compression (bump) and
rebound damping.
NOTE: Keep your damper settings at the street positions when operating your vehicle on
the street.
WARNING!
Only experienced track drivers should ma ke adjustments to the suspension settings.
Improper suspension adjustment can disrupt the balance of the vehicle and lead to a
loss of control or accident.
CAUTION!
Do not make any adjustments or modifications to the nitrogen pressure of the damper
canisters. This will void the warranty.
• The ACR suspension was designed and tuned with an uncompromising focus on handling. The ride response to road conditions m ay be harsher than expected from a
typical sports car.

INSTRUMENT CLUSTER WARNING LIGHTS
- Tire Pressure Monitoring System (TPMS) Light
• Each tire, including the spare (if provided), should be checked monthly, when coldand inflated to the inflation pressure recommended by the vehicle manufacturer on
the vehicle placard or tire inflation pressure label. (If your vehicle has tires of a
different size than the size indicated on the v ehicle placard or tire inflation pressure
label, you should determine 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-inflat ed. Accordingly, when the low tire
pressure telltale illuminates, 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 subs titute 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 malfunction exists.
• When the malfunction indicator is illuminated, 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
malfunction telltale after replacing one or more tires or wheels on your vehicle, to
ensure that the replacement or alternate tires and wheels allow the TPMS to continue
to function properly.

WHAT TO DO IN EMERGENCIES
CAUTION!
The TPMS has been optimized for the original equipment tires and wheels. TPMS
pressures and warning have been established for the tire size equipped on your
vehicle. Undesirable system 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 tire sealant from a can, or balance
beads if your vehicle is equipped with a TPMS, as damage to the sensors may result.
- Engine Temperature Warning Light
• This light warns of an overheated engine condition.
• If the light turns on and a warning chime sounds while driving, safely pull over andstop the vehicle. If the A/C system is on, t urn it off. Also, shiftthe transmission into
NEUTRAL and idle the vehicle. If the temperat ure reading does not return to normal,
turn the engine off immediately.
• We recommend that you do not operate the vehicle or engine damage will occur. Have the vehicle serviced immediately.
WARNING!
A hot engine cooling system is dangero us. You or others could be badly burned by
steam or boiling coolant. You may want to call an authorized service center for service
if your vehicle overheats.
- Brake Warning Light
• The Brake Warning light illuminates when there is either a system malfunction or the parking brake is applied. If the light is on and the parking brake is not applied, it
indicates a possible brake hydraulic malfunction, brake booster problem or an
Anti-Lock Brake System problem.
• We recommend you drive to the nearest service center and have the vehicle serviced immediately.
WARNING!
Driving a vehicle with the red brake light on is dangerous. Part of the brake system
may have failed. It will take longer to stop the vehicle. You could have an accident.
Have the vehicle checked immediately.

- Malfunction Indicator Light (MIL)
• Certain conditions, such as a loose or missing gas cap,poor fuel quality, etc., may
illuminate the MIL after engine start. The vehicle should be serviced if the light stays
on through several typical driving cycles. In most situations, the vehicle will drive
normally and not require towing.
• If the MIL flashes when the engine is running, serious conditions may exist that could lead to immediate loss of power or severe catalytic converter damage. We recommend
you do not operate the vehicle. Hav e the vehicle serviced immediately.
- Charging System Light
• This light shows the status of the electrical ch arging system. If the charging system
light remains on, it means that the vehicle is experiencing a problem with the charging
system.
• We recommend you do not continue driving if the charging system light is on. Have the vehicle serviced immediately.
- Oil Pressure Warning Light
• This light indicates low engine oil pressure. If the light turns on while driving, stop thevehicle and shut off the engine as soon as possible. A chime will sound for four
minutes when this light turns on.
• We recommend you do not operate the vehicle or engine damage will occur. Have the vehicle serviced immediately.
- Anti-Lock Brake (ABS) Light
• This light monitors the Anti-Lock Brake System (ABS).
• If the light is not on during starting, stays on, or turns on while driving, we recommendyou drive to the nearest service center and have the vehicle serviced immediately.
- Electronic Throttle Control (ETC) Light
