WARNING!

Safety instruction: Failure to observe this instruction can cause fatal or serious injury.

NOTICE!

Failure to observe this instruction can cause material damage and impair the function of the product.

NOTE

Supplementary information for operating the product.

2 Safety and installation instructions

Please observe the prescribed safety instructions and stipulations from the vehicle manufacturer and service workshops.

The manufacturer accepts no liability for damage in the following cases:

• Faulty assembly or connection
• Damage to the product resulting from mechanical influences and excess voltage
• Alterations to the product without express permission from the manufacturer
• Use for purposes other than those described in the operating manual

NOTICE!

To prevent the risk of short circuits, always disconnect the negative terminal of the vehicle's electrical system before working on it. If the vehicle has an additional battery, its negative terminal should also be disconnected.

WARNING!

Inadequate supply cable connections could result in short circuits, which could have as a consequence that:

• Cable fires occur
• The airbag is triggered
• Electronic control devices are damaged
• Electric functions fail (indicators, brake light, horn, ignition, lights)

Please observe the following instructions:

• When working on the following cables, only use insulated cable lugs, plugs and flat push-on receptacles:

• 30 (direct supply from positive battery terminal)

• 15 (connected positive terminal, behind the battery)
• 31 (return cable from the battery, earth)

Do not use terminal strips.

• The safest type of connection is to solder the ends of the cables together and then insulate them.

Only use insulated cable terminals, plugs and flat sockets for releasable connections. Do not use crimp terminals (cable connectors) or terminal strips.

• Use a crimping tool (fig. 1 10, page 3) to connect the cables.

• When connecting to cable 31 (earth), screw the cable

• To the vehicle's earth bolt with a cable lug and a gear disc or

• To the sheet-metal bodywork with a cable lug and a self-tapping screw.

Ensure that there is a good earth connection.

If you disconnect the negative terminal of the battery, all data stored in the volatile memories will be lost.

• The following data must be set again, depending on the vehicle equipment options:

• R a d i o c o d e

• Vehicle clock
• T i m e r
• On-board computer
• Seat position

You can find instructions for making these settings in the appropriate operating instructions.

Observe the following installation instructions:

• Secure the parts installed in the vehicle in such a way that they cannot become loose under any circumstances (sudden braking, accidents) and cause injuries to the occupants of the vehicle.
• To prevent damage, when drilling ensure that there is sufficient space on the other side for the drill head to come out (fig. 2, page 4).
• Deburr all drill holes and treat them with a rust-protection agent.

Observe the following instructions when working with electrical parts:

• When testing the voltage in electrical cables, only use a diode test lamp (fig. 1 8, page 3) or a voltmeter (fig. 1 9, page 3).

Test lamps with an illuminant (fig. 12, page 3) take up voltages which are too high and which can damage the vehicle's electronic system.

• When making electrical connections (fig. 3, page 4), ensure that

• They are not kinked or twisted

• They do not rub on edges

• They are not laid in sharp-edged ducts without protection.

• Insulate all connections.

• Secure the cables against mechanical wear with cable binders or insulating tape, for example to existing cables.

Observe the following instructions when using the seat heater:

• Do not place any sharp or heavy objects on the seat, as the seat heater could otherwise be damaged.
• Persons with an impaired sensitivity to heat should only operate the seat heating on level 1.
• Do not place any heat insulating objects, such as blankets or coats, on the seat when the seat heater is switched on.
• The seat heater can be damaged by fluids spilt on the seat.
• Never switch the seat heater on when it is wet.

6.2 Installing the seat heater

Removing the seat

Secure the vehicle against rolling away.

NOTICE!

For vehicles with side air bags in the seat backrest, observe the manufacturer's instructions on removing the seats and the upholstery.

Check the suitability for installation using these installation instructions and the manufacturer's information.
Remove the fastening screws from the vehicle seat.
Lift the seat out of the vehicle.

Preparing the seat

Remove all plastic panelling from the seat to ensure the fastening of the cover fabric can be reached.
Separate the backrest from the seat (fig. 7, page 5 and fig. 8, page 5).

Open the seat cover on the seat surface.

The cover fabric is usually tucked into a seam on the frame with a wide cardboard strip or metal wire.

Remove the fasteners using a screwdriver and pliers (fig. 9, page 5 and fig. 10, page 5).
Remove any upholstery staples or cross braces (fig. 11, page 5).

Open the cover of the backrest in the same way.

Preparing the heating elements

NOTICE!

Insulate all the trimmed ends with the insulating material supplied to prevent a short circuit.

NOTE

• You can cut the heating elements to the required length and shorten the lengths of the two conductor paths.

• You can cut out a section of the heating element in the area of the anchoring grooves on the seat or the backrest. Make sure the cut-out sections are only made between the two black seams (fig. 5, page 4).

• Do not cut the mat lengthways, otherwise it will not be heated in the area of the incision (fig. 5, page 4).

• The heating surface on the backrest only needs to extend approx. 30 - 35 ~cm above the seat, as the driver only leans against this area when sitting normally (fig. 6, page 4).

Place the heating elements on the seat and backrest.
If there are anchoring grooves in the seat or the backrest, mark these areas on the heating elements.

Mark the required lengths. Take into account the depth of the anchoring grooves, if present. The heating element is inserted in these anchoring grooves.
Trim the heating element to the required length.
Customise the cut-out sections as required.
Insulate all the trimmed ends with the insulating material.

Installing the heating element for the seat surface

Insert the heating element for the seat surface between the cover fabric and the foam core of the seat (fig. 12, page 5).
If anchoring grooves are present, make sure that the cut-out sections are positioned over the anchoring grooves (fig. 13, page 5) and place the heating elements in the anchoring grooves.
Fasten the heating element using double-sided adhesive tape to prevent it sliding on the foam core.

Ensure that no creases or kinks form.

Installing the heating element for the backrest

NOTICE!

If the seats are equipped with side airbags, then there is a predetermined breaking point in the cover fabric. The seat cover must therefore not be pulled tightly or slip out of place.

Open the lower area of the backrest cover (fig. 14, page 5).
Push the heating element into the gap between the seat cover and the seat cushion (fig. 15, page 5).
Fasten the heating element using double-sided adhesive tape to prevent creases.

Installing the seat

Reassemble the backrest and seat.
Lift the seat into the vehicle.
Secure the vehicle seat with the fastening screws.
