Parking heater

WARNING:
The parking heater must not be operated at filling stations, near sources of combustible vapours or dust or in enclosed spaces.

The parking heater operates independently of the vehicle heater by heating the engine’s coolant circuit. It is fed from the vehicle fuel tank. You can also use it while the vehicle is in motion to help the vehicle heater warm up the interior more quickly.

Used properly, the parking heater provides the following benefits: • It preheats the interior of the vehicle.

• It keeps the windows clear of ice in the event of frost and prevents condensation.

• It avoids cold starts and allows the engine to reach operating temperature sooner.

Note: The parking heater will only operate if there is at least 7.5 litres (1.6 gallons) of fuel in the fuel tank and the ambient temperature is below 15°C (59°F). The heater will not operate if the battery is low.

Note: The heating depends on the outside air temperature.

Note: When the parking heater is activated, exhaust fumes may come from under the sides of the vehicle. This is normal.

Note: On vehicles with a manual heating, ventilation and air conditioning system, the heating of the vehicle interior is dependent on the temperature, air distribution and blower control settings.

To prevent the battery from discharging: • Once the parking heater has performed one heating cycle, the next programmed heating cycle will only be carried out if you have started the vehicle’s engine in between.

• After a heating cycle, drive the vehicle for at least the period of the heating cycle.

Programming the parking heater

Note: The programmed time is the time at which you wish the vehicle to be warm and ready to drive, not the time at which the heater switches on.

Note: You must programme the times at least 70 minutes in advance of the time you wish to set.

Note: You must set the time and date correctly. See Clock.

To programme the heating times:

1. Press the right arrow button on the steering wheel to enter the main menu.

2. Highlight Setup with the up and down arrow buttons and press the right arrow button.

3. Highlight Park Heater and press the right arrow button.

• The functions Program 1 and Program 2 allow you to programme up to two heating cycles for each day of the week. These times will remain stored and the heater will warm up the vehicle at these times on these days every week.

• The function One-Time allows you to programme one heating cycle for one specific day.

• The function Active now automatically switches on the heater.

Programming the functions Program 1 and Program 2

1. Highlight Program 1 and press the right arrow button.

Remote starting

The parking heater may be started and switched off from a distance of up to 500 metres (1640 feet) using the supplied remote control transmitter. This range will vary depending upon local conditions and terrain, as well as battery condition. The remote control transmitter will indicate whether or not the signal has been received. The parking heater will operate for a maximum of 30 minutes.

Note: The heater will operate, depending on the ambient temperature, for between 10 and 30 minutes. The interior will cool down after the heating period has elapsed, therefore a remote start more than 30 minutes before driving is not recommended.

Note: The remote control may not always receive confirmation of a successful remote command at extended operating ranges.

Starting

Hold the transmitter with the antenna upwards and press the ON button for at least two seconds. The LED on the transmitter lights up green to confirm the signal has been received.

Switching off

Hold the transmitter with the antenna upwards and press the OFF button for at least two seconds. The LED on the transmitter lights up red to confirm the signal has been received.

Remote start in combination with direct start or timer

Remote start is integrated with normal heater control. Parking heaters started with direct start or timer functions can be switched off with the remote control transmitter and vice versa.

Feedback during starting and switching off

The LED on the transmitter illuminates green for about two seconds. This indicates the signal has been received by the vehicle and the heater has started.

The LED on the transmitter illuminates red for about two seconds. This indicates the signal has been received by the vehicle and the heater has switched off.

The LED on the transmitter flashes green or red for about two seconds. This indicates the signal was not transmitted correctly. Repeat the transmission.

The LED on the transmitter illuminates orange for about two seconds before showing green or red. This indicates the transmitter batteries are weak and should be changed.

The LED on the transmitter flashes orange for about 5 seconds. This indicates that the signal was not transmitted. The transmitter batteries are discharged and should be changed as soon as possible.

Changing the remote control battery

Make sure that you dispose of old batteries in an environmentally friendly way. Seek advice from your local authority regarding recycling.

1. Insert a screwdriver or other suitable tool into the slot on the back of the remote control, and unscrew the compartment cover.

CAUTION:
Do not touch the battery contacts or the printed circuit board with the screwdriver.

2. Carefully prise out the battery.

3. Install a new battery (3.3V type CR1-3N) with the + facing upwards.

4. Re-assemble the remote control.

Programming the transmitter

Further transmitters may be used with the remote system, please consult your dealer. Up to a maximum of 3 separate remote controls may be added. When adding extra transmitters these must be programmed separately.

Note: The heater must be switched off during programming.

Note: The programming procedure may be repeated as often as is required. The oldest programmed transmitter will be deleted each time.

1. Install the battery in the new transmitter.

2. Turn off the power to the receiver by removing fuse F32 from the engine compartment fuse box. See Fuse specification chart.

3. Wait for at least 5 seconds.

4. Reconnect power to the receiver by replacing the fuse, and press the OFF button on the new transmitter within 5 seconds until the LED light turns off.

5. The new transmitter is now programmed.
