1. Seat heater system will NOT
cover glued to foam pad) method of trim cover attachment.

2. If the vehicle is equipped with an anti-theft radio, the radio code must be written down prior
to disconnecting battery cable. The code must be re-entered when the negative battery
cable is re-installed.

3. If vehicle is equipped with an air bag, it is advisable to disconnect negative battery cable for
3 minutes prior to beginning installation.

4. Only use parts and components supplied in kit for the seat heater installation. The supplied
components are carefully selected for optimal performance. Foreign parts may lead to problems
which could result in potential damage to the seat heater components or vehicle.

5. The installation of the heating pads must be free of creases and wrinkles.

6. Seats in vehicles with pre-loaded (power charge equipped) safety belts must be removed and
re-installed under strict adherence to the vehicle manufacturers instructions.

7. In cases where a seat is equipped with an occupant pressure sensor for air bag deployment;
please refer to the manufacturer’s manual for any specific instruction with regard to installing
seat heater kits.

8. After installing seat heater wire harness, care must be taken to ensure all seat motions are still
possible without obstruction and the moving of the seat does not cause any interference that
could damage the seat heater wire harness.

9. Installation of a CARBONTECH™ seat heater system with seats containing seam lines
running front to rear (length wise) is not permitted. Only exception is if the heating pads are
not directly located over the groove/s.

10. The overall side to side (width) of the heating pads must not be altered (cutting not

permitted).

11. Both heating pads must be connected to ensure system functions properly.

Warning: Metal, electrical conductors or hog rings are not to be placed on, through or

across the heating element.

Seat Cushion:

1. Prior to removing seat from vehicle, lay heating pads on seat to verify size & fit.

2. Secure car on a level surface.

3. Disconnect the negative battery cable or make sure that the area to be worked within is

grounded. If you have any doubt concerning the layout of the vehicle wire harness, consult
the wiring diagram provided by the manufacturer.

4. Remove seat from vehicle and place on a suitable work table/area.

Note: Make certain to disconnect all wire connectors prior to removing seat from

vehicle.

5. Disassemble seat as needed to gain access to seat cushion cover attachment clips.

6. Unsnap j-clips and or remove

7. Measure the width of the center seat area between the

longitudinal seams.

Note: The width must be at least 250 mm (10 in).

The heating pad CANNOT contact the side seams of the
seat. If it does make contact, the seat heater cannot be
installed. See Fig 3

8. Position the heating pad with the label facing down and the wire harness routed towards the
back of the seat area. Adjust the pad so the thermostat is located approx. 25-50 mm (1-2
in) forward of the back rest. In cases where the seat cushion contains lateral grooves (side
to side) to allow for trim cover attachment, a section of the heating pad will need to be cut
out. See Fig 4

Fig 4

9. Once the area that needs to be cut out is marked, remove the heating pad from the cushion.

Measure in board (towards Center of pad) on each side
40mm (9/16 in) and mark. This is necessary to ensure
that the main power supply for the heating pad does
not get damaged or cut. See Fig 5

10. Cut out the marked area. With the section removed, wrap lateral "bridges" with the supplied
black insulation tape. Repeat procedure on remaining sides of cut out. See Fig 6

11. Reposition heating pad onto cushion foam. Make sure thermostat is in the correct location.

(see step 9) Using the supplied gold double sided tape, attach the back edge of the heating pad
to the cushion foam. With the pad attached at the rear, determine the final length.

Note: Make sure that the length difference between the cushion pad and back rest pad is not
more than 275 mm (10-3/4 in). See Fig 7

12. Trim if needed and attach using the supplied gold double sided tape.

Note: Seat heater pad should reach the forward edge of the seat cushion. See Fig 8

Fig 7

13. Route the heating pad wire harness so that it exits the trim cover in an inconspicuous area.

14. Installation is now complete. Double check to make sure the pad does not have any

wrinkles or is folded over onto itself. Once checked, carefully re-attach trim cover.

Back Rest:

1. Follow the same order and procedures for steps 5-13 for installing the heating pad to the
back rest.

Note: For step 11, use 2 pieces of gold double sided tape. One at the top and the other

approximately half way down to ensure the pad will not loosen and wrinkle over
time due to effects of gravity.
