SAFETY HARNESSES
Your vehicle is equipped with a SCHROTH safety harness system. Your harness must be worn, adjusted and
maintained properly. Demonstrations and instructions regarding the effective and safe use of your racing
harnesses are included in the SCHROTH on-line user manual, which you will find on the CD in your Ariel Atom
Owner’s Packet. Reading and adhering to the information in the SCHROTH on-line user manual is imperative
for the safety of drivers and passengers of your vehicle. Information on the CD includes but is not limited to:
▪Wearing, adjusting and releasing the racing harness
▪Anchorage locations and geometries
▪Belt routing
▪Overview of the Anti Submarining Mechanism (ASM®)
▪Care and maintenance of the harnesses
▪Replacement information (Harnesses must be replaced before the expiration date listed on the label.)
To access the on-line user manual:
1. Insert the CD into your disk drive
2. Open the SCHROTH CD Rom folder
3. Open the folder titled “English”
4. Open the HTML document titled “main.htm”
5. Click on “Installation and Instructions”
6. Open each folder in the left column for instructions and information
WARNING: SCHROTH racing harnesses are designed for individuals weighing more than 88 lbs
(40 kg), and with a height greater than 4 ft. 11 in. (150 cm).

ON-BOARD EXTINQUISHER SYSTEM
▪If you have chosen the on-board extinguisher system, the fire extinguisher bottle is located under the dash,
at the longitudinal midline of the car, and is placed horizontally and perpendicular to the long axis, above
the parking brake pull mechanism.
▪There are two pull handles for the extinguisher. The safety crew handle is located on the windscreen base
at the right side of the car ahead of the mirror base. The driver’s handle is between the instrument panel
and the parking brake handle.
▪The pull handles are marked “FIRE” and include a safety pin with a blue flag attached.
▪Before driving your vehicle, check the gauge on your extinguisher to ensure that it is fully charged.
▪Please refer to the Safecraft Installation Suggestions and Hints documents included in your Ariel Atom
Owner’s Packet.

START SEQUENCE
The
Remote Keyless
Immobilizer
▪When the immobilzer
indicator light is flashing
moderately, the anti-theft
system is armed. The
flashing light will blink rapidly
when the ignition is on (the
system will still be armed).
▪To unarm the system, wave
the key fob in range of the
transponder antennae (#2 in
diagram). The light will go
off, and the car is then able
to start.
▪After you kill the ignition
switch the light will stay on
solid for 20 seconds.
▪If the starter switch is not
pushed within 20 seconds,
the system will re-arm, and
the sequence will need to be
repeated.

SHIFT PATTERNS

VEHICLE RUN-IN PROCEDURES
Your vehicle does not need an elaborate break-in; however, it will perform better in the long run if you follow
these guidelines:
▪Do not drive at any one constant speed, fast or slow, for the first 500 miles (800 km).
▪Do not make full-throttle starts.
▪Do not exceed 5,000 engine RPM.
▪Avoid downshifting to brake or slow the vehicle.

12
BRAKE BEDDING PROCEDURES
Your Ariel Atom 2 will be delivered with set-up, testing, and checks already completed by the factory; however,
the braking system will still need to be completely bedded-in before any high speed or very hard deceleration is
attempted. Refer to the following schedule for brake bed-in procedures.
The first 10 miles (16 km): Light braking from 50–60 MPH (80-96 km/h) down to 30 MPH (48 km/h). Perform
this protocol for five iterations allowing time for the brakes to cool between iterations. Avoid any high speed
stops down to zero. Braking from high speeds heats the disc surface while the interior remains cool and
contributes to warping before the brakes are fully bedded.
The first 10-100 miles (16-160 km): Increase braking pressure from about 60 MPH (96 km/h) to zero.
Observe for the area around the mounting bolts to turn light blue. This coloration indicates correct heat soak is
being achieved. Avoid full stops from 70 plus MPH (112 km/h).
The first 100-200 miles (160-322 km): Gradually increase brake pressure coming to full stops more rapidly
than during the previous step. After this point, full braking from speed should be possible without warping the
discs or experiencing unusual vibration.
For track day use:
▪Warm, but do not overheat, the brakes during the warm up lap(s).
▪Allow the brakes to cool during a “cool down” lap at the end of the session.
▪Do not leave your foot on the brake after stopping in the paddock area following braking from high speeds.
This action would create a “hot spot” and contribute to warping the rotors.
NOTE: To avoid warping, avoid excessive or uneven heating of the rotors.

13
JACK POINTS
At the front of the vehicle, the mounting point where the front of the lower A-arm attaches to the frame is the
preferred jacking point. At the rear of the vehicle, the lower horizontal tube is the preferred jacking point.

14
JACKING UP THE CAR
▪The use of wheel chocks or blocks is required when jacking up the car.
▪Jack stand locations are suitable for full lift and single end elevated requirements.
▪Use care to not damage the radiator or after cooler radiator when positioning jack.
▪Use rags or cardboard between the jack and the frame, as well as between the jack stands and frame,
to avoid scratching the frame’s finish.
Procedures:
1. Position the floor jack directly under the front lower A-arm bushing bracket.
2. Locate the jack stands on right and left sides of car directly under the longitudal tube of lower chassis.
3. Locate one of the jack stands directly under the rear bottom cross member as far to the left side as
possible.
4. Position the floor jack directly under the rear bottom cross member at the centerline of car.
5. Locate one of the jack stands directly under the rear bottom cross member as far to the right side as
possible.
Never get under your vehicle when it is only supported by a jack.
