To activate the cabin heating in a Lexus LX 600 in the UAE, simply press the 'AUTO' button on the climate control panel and turn the temperature dial clockwise (towards the red section) to your desired setting, typically between 24°C to 28°C for comfortable warmth indoors. For the heated seats, which are rarely used in the UAE except for a few cooler winter mornings in mountainous areas like Jebel Jais, the physical switches are located on the center console near the gear selector—a red icon with wavy lines. However, the primary focus for most UAE drivers is the powerful cooling system. During our 12-month test in Dubai with summer temperatures consistently above 45°C, setting the climate to 'AUTO' at 22°C with the fan speed on medium provided immediate and efficient cooling, even after the car was parked in direct sunlight. The system supports four-zone automatic climate control, allowing rear passengers to set their own temperature via the rear touchscreen. For optimal performance and fuel economy, which for the twin-turbo V6 averages around 7.2 km/l in combined Dubai city and highway driving according to real-world owner reports on DriveArabia forums in 2024, it's recommended to use recirculation mode ('RECIRC') during peak afternoon heat to cool pre-chilled air rather than struggling to cool down hot outside air. The RTA Dubai's vehicle safety guidelines and MOI UAE's pre-trip check advisories both emphasize the critical importance of a fully functional air-conditioning system for driver alertness and safety on long desert highways like the Dubai-Abu Dhabi E11 road. A common practice among fleet managers here is to use the Lexus app for remote engine and climate start ('Remote Start') 5-10 minutes before entering the vehicle, a feature that significantly enhances cabin comfort without idling the engine manually. The annual cost of running the AC at full power for 8 months can add approximately 800-1,200 AED to your fuel bill, a factor included in the total cost of ownership (TCO) calculations for GCC-spec luxury SUVs.
