Video tutorial

In this video, we see that the "rest" mode in the Citroen C4 is an intelligent function that maintains ventilation in the cabin for a few minutes after the engine is turned off, utilising the residual heat from the engine or the air conditioning (if activated before shutdown).

To activate it, ensure the air conditioning is on before turning off the engine; after shutdown, press the "rest" button on the climate panel (it will light up). Air will continue to circulate for 15/30 minutes, depending on the outside temperature and battery charge.

It is ideal for short stops while waiting in the car; it uses residual energy without consuming fuel. For example, during a winter trip, press "rest" to keep the cabin warm while refuelling.

How to Remove the Rear Seat of a Hyundai Tucson?

To remove the rear seat of a Hyundai Tucson, follow these steps. Start by moving the front seats to their most forward position to gain space. Next, locate the release lever on the underside of the rear seat, near the floor. Press this lever down while pulling the seat upwards to unlock it from the anchor pins. Once unlocked, tilt the seat upwards and forwards to remove it from its position. Repeat this process for both sides of the rear seat. Be careful of any electrical cables or components that may be connected to the seat during removal. Once the rear seat is removed, the disassembly is complete.
