2023 Land Rover Defender CLIMATE AND COMFORT Owners Manual

CLIMATE SETTINGS

To view the Climate settings menu, touch the settings icon, then select Climate. See FRONT CLIMATE CONTROL.

• Air purity: The air purity system detects specific harmful gases such as those found in the city traffic. The air purity system controls the automatic recirculation mode to prevent polluted air entering the cabin.
• Auto air flow: The blower speed, for automatic operation, can be set to Soft and Quiet, Balanced, or Powerful and Fast.
• Auto blinds: The auto operation of the roof blind can be enabled or disabled.
• Automatic heated screens: Automatic operation of the heated windscreen and the heated rear screen can be enabled or disabled.

AIR QUALITY

To monitor and adjust the air quality:

1. Touch the apps icon on the touchscreen driver side bar. See TOUCHSCREEN HOME MENU.
2. Select CLIMATE.
3. Select AIR QUALITY.

Air quality menu:

1. Purify: When Purify is enabled, the system automatically reduces allergens and particulates at and below 2.5 microns, harmful gases and odours within the cabin. Enabling Purify also activates the air quality sensor system which stops polluted air from entering the cabin.
2. CO2: The CO2 management feature ensures CO2 does not build up in the cabin. The CO2 management feature monitors the concentration of carbon dioxide gas in the cabin and selectively opens the recirculation door to let in fresh air to return balance to the cabin air environment. Controlling the CO2 in the cabin reduces the risk of driver drowsiness. The CO2 feature is represented by the white arrows on the vehicle graphic. The white arrows animate when the system is actively balancing the cabin environment.
3. Ion: When activated, the Ion feature creates OH radicals to purify the air in-vehicle. The Ion feature is represented by the blue dots on the vehicle graphic.
4. Exterior AQI: Launches Air Quality Index (AQI) app. AQI app data is received from an air quality data provider and gives a detailed view of the air quality for the current location. Alternatively the AQI app can display air quality data for a destination that is set in the navigation system or for user-searched locations.
   NOTES
   A data subscription is required to access AQI data.
   NOTES
   The AQI app is not available in all markets.
   NOTES
   The performance of the Exterior AQI feature is dependent on the availability of data from the nearest monitoring station.
5. Information: Further information about air quality features and capabilities.
6. The interior particulate matter concentration. Ranges from green (good) to red (hazardous).
7. Exterior air quality as denoted by a colour scale. Ranges from green (good) to red (hazardous)
8. Interior air quality as denoted by a colour scale. Ranges from green (good) to red (hazardous)
9. The exterior particulate matter concentration. Ranges from green (good) to red (hazardous).

AUXILIARY HEATER

WARNING
Do not operate the auxiliary heater when refuelling the vehicle. Doing so may cause fuel vapours to combust, potentially causing a fire or explosion.

WARNING
Do not operate the auxiliary heater while the vehicle is in an enclosed space. Doing so can cause a build-up of highly toxic fumes, which may cause unconsciousness or death.

The auxiliary heater is powered by fuel drawn from the vehicle’s tank. The auxiliary heater operates at low ambient temperatures and helps to boost the temperature of the engine’s coolant. Raising the temperature of the engine’s coolant improves cabin heating and engine starting performance. It can also be controlled by the timed climate control system or from the timed climate remote control.

When the auxiliary heater is operating, exhaust fumes from the heater may be visible exiting from under the front of the vehicle. Exhaust fumes from the auxiliary heater are normal and are not a cause for concern.

TIMED CLIMATE

The timed climate system, when in operation, provides a comfortable temperature inside the cabin in advance of using the vehicle. The timed climate system can also maintain a temperature when leaving the vehicle for a short period of time.

The timed climate system draws in fresh air to cool and ventilate the cabin, or operates the auxiliary heater to heat the cabin. Heating or cooling of the cabin is selected by the timed climate system and is dependent on the external temperature.

The timed climate system can be controlled via the touchscreen, or it can be operated using the timed climate remote. The touchscreen control has options for either timed or manual settings.

The timed climate system may not operate, or switches off automatically, in the following scenarios:

• If the fuel level is low.
• If the vehicle’s battery charge is low.
• If the coolant temperature is at, or above, its required temperature.
• If the system has been in operation for 30 minutes.

TIMED CLIMATE TOUCHSCREEN CONTROLS

The touchscreen can be used to either preset activation times or to operate the system manually.

When the system is operating, the LED in the climate control AUTO or Max A/C button flashes. AUTO indicates that the engine or cabin is being heated. Max A/C indicates the that cabin is being ventilated. The choice of operation is automatically determined by the system, depending on the external temperature.

To access the timed climate screen, select VEHICLE DEPARTURES from the apps screen page. See APPS SCREEN.

1. Power icon: Touch to switch the timed climate system on or off.
2. Current time.
3. Settings icon: Touch to select the settings screen. See SYSTEM SETTINGS.

Event icon.

Touch an event icon to switch on, edit, or delete an event.

2. Repeat every: Touch to enable the event to be repeated on other days.
3. Day: Touch to select the days that require the repeated event.
4. Hour arrows: Touch to adjust the hour.
   NOTES
   12 or 24 hour clock can be selected via the Time and Date settings. See GENERAL SETTINGS.
5. Minute arrows: Touch to adjust the minutes.
6. Delete icon: Touch to delete the event.
7. OK: Touch to set the event.

The auxiliary heater can be manually operated via the touch screen when the vehicle’s ignition is off.

Manually operate the system as follows:

1. Heat now: Touch to heat the cabin and engine via the auxiliary heater. Touch again to turn off.
2. Vent now: Touch the circulate air through the cabin. Touch again to turn off.

TEMPERATURE DIFFERENTIATION

The temperatures selected via the climate control system are perceived values. The system operates to achieve these selected values. The selected value does not represent the output temperature from the air vents. Air vent output temperature varies as the system automatically adjusts the vent outputs to achieve the set temperatures.

The actual temperature in the cabin may differ from the set temperatures due to internal and external factors, including ambient temperature, sun load, and direction. The climate control system automatically adjusts the airflow level, direction, and temperature to compensate for these internal and external factors. Automatic adjustments in the air vent outputs may result in some temperature differentiation within the cabin.
