2010.5 Citroen DS4 instrument panel

Operating fault
If an operating fault occurs, when reverse gear is engaged this warning lamp is displayed in the
instrument panel and/or a message appears in the screen, accompanied by an audible signal (shor t beep). Contact a CITROËN dealer or a qualified workshop.
In addition to the rear parking sensors, the front parking sensors are triggered when an obstacle is detected in front and the speed of the vehicle
is still below 6 mph (10 km/h). The sound emitted by the speaker (front or rear) indicates whether the obstacle is in front or behind. The front parking sensors are interrupted if the vehicle stops for more than three seconds in for ward gear, if no fur ther obstacles are detected or when the speed of the vehicle exceeds 6 mph (10 km/h).
The function will be deactivated automatically if a trailer is being towed or a bicycle carrier is fitted (vehicle fitted with a towbar or bicycle carrier recommended by CITROËN).
In bad weather or in winter, ensure that the sensors are not covered with mud, ice or snow. When reverse gear is engaged, an audible signal (long beep) indicates that the sensors may be dir ty. When the vehicle is moving at a speed below 6 mph (10 km/h), cer tain sound sources (motorcycle, lorry, pneumatic drill, etc.) may trigger the audible signals of the parking sensor system.
Deactivation/Activation of the front and rear parking sensors
The function is deactivated by pressing this button. The indicator lamp in the button
comes on. Pressing this button again reactivates the function. The indicator lamp in the button goes off.

The oil must correspond to your engine and conform to the manufacturer's recommendations.
Brake fluid level
Changing the fl uid
Refer to the Maintenance and Warranty Guide for the inter val for this operation.
Fluid specifi cation
The brake fluid must conform to the manufacturer's recommendations and meet the DOT4 standard.
The brake fluid level should be close to the "MA X" mark. If it is not, check the brake pad wear.
The reading will only be correct if the vehicle is on level ground and the engine has been off for more than30 minutes. The check is carried out either when the ignition is switched on using the oil level indicator in the instrument panel, or using the dipstick.
When working under the bonnet, take care, as cer tain areas of the engine may be extremely hot (risk of burns).

Following prolonged operation of the vehicle at very low speed or at idle, you may, in exceptional circumstances, notice the emission of water vapour at the exhaust on acceleration. This does not affect the behaviour of the vehicle or the environment.
Manual gearbox
The gearbox does not require any maintenance (no oil change). Refer to the Maintenance and Warranty Guide for the details of the level checking inter val for this component.
According to your version of instrument panel, the start of saturation of the particle emissions filter is indicated by:
6-speed electronic gear

Removing a wheel
Parking the vehicle
Immobilise the vehicle where it does not block traffic: the ground must be level, stable and non-slippery ground. Apply the parking brake unless it has been programmed to automatic mode, switch off the ignition and engage first gear * to lock the wheels. Check that the braking warning lamps in the instrument panel are on (not flashing). If necessary, place a chock under the wheel diagonally opposite the wheel to be changed. The occupants must get out of the vehicle and wait where they are safe. Never go underneath a vehicle raised using a jack; use an axle stand.
