To reset the service light, turn the ignition to the "on" position without starting the engine. Press and hold the trip reset button on the dashboard. While holding the button, switch the ignition off and then back on. Continue holding the button until the service light turns off, which should take about 10 seconds.
The recommended engine oil for the Citroën DS4 2018 is fully synthetic 5W-30 oil that meets ACEA C2 specifications. Always refer to your owner's manual for confirmation.
To connect your smartphone, ensure Bluetooth is activated on your phone. On the vehicle's touchscreen, navigate to the Bluetooth settings and select "Add Device." On your phone, search for Bluetooth devices and select "Citroën DS4." Enter the PIN displayed on the vehicle's screen into your phone to pair the devices.
First, ensure the vehicle is on a flat surface and apply the parking brake. Loosen the lug nuts on the flat tire slightly. Use the jack to lift the car until the tire is off the ground. Remove the lug nuts and the tire. Place the spare tire on the hub, tighten the lug nuts by hand, then lower the car and tighten the nuts fully in a crisscross pattern.
If the battery is charged but the car won't start, check the starter motor, fuses, and ignition switch. Ensure the gear is in 'Park' or 'Neutral'. If the problem persists, it may require professional diagnostics to check for issues like a faulty alternator or immobilizer system.
Locate the cabin air filter housing under the dashboard on the passenger side. Remove the panel and any screws or clips securing the filter cover. Slide out the old filter and insert the new filter with the airflow direction arrow pointing in the correct direction. Replace the cover and panel.
Check the tire pressures with a gauge and inflate them to the recommended levels specified in the owner's manual or on the placard in the driver's doorjamb. After adjusting the pressures, drive the car for a few minutes to allow the system to reset. If the light remains on, there may be a fault in the sensor.
The Citroën DS4 2018 typically requires servicing every 12,000 miles or 12 months, whichever comes first. However, it's important to follow the service schedule outlined in the owner's manual, as it may vary based on driving conditions and local regulations.
It's recommended to use ethylene glycol-based antifreeze with organic additives suitable for aluminum engines. To check the level, ensure the engine is cool, then locate the coolant reservoir under the hood. The level should be between the 'MIN' and 'MAX' marks on the side of the reservoir.
For front-wheel drive vehicles like the Citroën DS4 2018, the recommended tire rotation pattern is to move the front tires to the rear on the same side, and cross the rear tires to the front. Regular rotation helps ensure even tire wear and prolongs tire life.
