ESP Citroen DS4 2010.5 1.G User Guide

The sidelamps and dipped beam headlamps are switched on automatically, without any action on the par t of the driver, when a low level
of external light is detected or in cer tain cases of activation of the windscreen wipers. As soon as the brightness returns to a sufficient level or after the windscreen wipers are switched off, the lamps are switched off automatically.
Automatic illumination of headlamps
Activation
 Turn the ring to the "AUTO" position. The automatic illumination of headlamps is accompanied by a message in the screen.
Deactivation
 Turn the ring to another position. Deactivation is accompanied by a message in the screen.
Associated with the automatic "Guide-me-home" lighting
Association with the automatic lighting provides the "guide-me-home" lighting with the following additional options: - selection of the lighting duration of 15, 30 or 60 seconds in the vehicle parameters
in the vehicle configuration menu, - automatic activation of "guide-me-home" lighting when automatic lillumination of headlamps is in operation.
Parking lamps
Side markers for the vehicle by illumination of the sidelamps on the traffic side only.  Within one minute of switching off the
ignition, operate the lighting control stalk up or down depending on the traffic side (for example: when parking on the left; lighting control stalk upwards; the right hand sidelamps are on). This is confirmed by an audible signal and illumination of the corresponding direction indicator warning lamp in the instrument panel. To switch off the parking lamps, return the lighting control stalk to the central position.

Cornering lighting
With dipped or main beams, this function makes use of the beam from a front foglamp to illuminate the inside of a bend, when the vehicle speed is below 25 mph (approximately 40 km/h)
(urban driving, winding road, intersections, parking manouevres...).
Switching on
with cornering lighting
without cornering lighting
Switching off
The system does not operate: - below a cer tain angle of rotation of the steering wheel, - above 25 mph (40 km/h), - when reverse gear is engaged,
The system is activated by default.
Programming
The system is activated or deactivated in the vehicle configuration menu.
This function star ts: - when the corresponding direction indicator is switched on, or - from a cer tain angle of rotation of the steering wheel.

Courtesy lamps
In this position, the cour tesy lamp comes on gradually:
Front and rear courtesy lamps
- when the vehicle is unlocked, - when the key is removed from the ignition, - on opening a door, - when the remote control locking button is used to locate your vehicle.
It switches off gradually: - when the vehicle is locked, - when the ignition is switched on, - 30 seconds after the last door is closed.
Permanently off.
Permanent lighting.
In permanent lighting mode, the lighting time varies according to the circumstances: - with the ignition off, approximately ten minutes, - in energy economy mode, approximately thir ty seconds, - with the engine running, unlimited. When the cour tesy lamp is in the "permanent lighting" position, the rear cour tesy lamp also comes on, except if it is in the "permanently off " position. To switch off the rear cour tesy lamp, put it in the the "permanently off " position.

 With the ignition on, press the corresponding switch.
Take care not to put anything in contact with the cour tesy lamps.

Tyre under-infl ation detection
System which automatically and continuously checks the pressure of the tyres while driving. Sensors fitted in each valve trigger a warning in the event of problem (speed above 12 mph (20 km/h)).
Puncture
The tyre under-inflation detection system is an aid to driving which does not replace the need for the driver to be vigilant or to drive responsibly.
Under-infl ated tyre
This warning lamp is displayed on the instrument panel and/or a message appears in the screen, accompanied by an audible
signal, to identify the wheel concerned.
The STOP warning lamp comes on and/or this warning lamp is displayed on the instrument panel, accompanied by
an audible signal and a message in the screen identifying the wheel concerned.
 Stop as soon as it is safe to do so, avoiding any sudden movement of the steering wheel and the brakes.  Repair or change the damaged wheel (punctured or very deflated tyre), and have the tyre pressure checked as soon as possible.
 Check the tyre pressures as soon as possible. This check must be carried out when the tyres are cold.

175Safety
Emergency braking assistance
System which, in an emergency, enables you to obtain the optimum braking pressure more quickly, thus reducing the stopping distance.
Activation
It is triggered by the speed at which the brake pedal is pressed. The effect of this is a reduction in the resistance of the pedal and an increase in braking efficiency.
When braking in an emergency, press firmly without releasing the pressure.
Trajectory control systems
Anti-skid regulation (ASR)
and electronic stability
programme (ESP)
The anti-skid regulation (also known as Traction Control) optimises traction to prevent skidding of the wheels, by acting on the brakes of the driving wheels and on the engine. The electronic stability programme acts on the brake of one or more wheels and on the engine to keep the vehicle on the trajectory required by the driver, within the limits of the laws of physics.
Activation
These systems are activated automatically each time the vehicle is star ted. They come into operation in the event of a grip or trajectory problem.
This is indicated by flashing of this warning lamp in the instrument panel.
Snow driving assistance
(Intelligent Traction Control)
Your vehicle has a system to help driving on snow: Intelligent Traction Control . This automatic system continuously checks for situations of difficult sur face adhesion that could make it difficult to move off or make progress on deep fresh snow or compacted snow. In these situations, Intelligent Traction Control takes over from the ASR system, limiting the amount of wheel slip to provide the best traction and trajectory control, even
without snow tyres and with or without chains. In extremely severe conditions (snow on top of ice, sand, deep mud…), it can be useful to
deactivate the ESP/ASR systems to allow a degree of wheel spin and so recover grip.

Deactivation
In exceptional conditions (star ting a vehicle which is bogged down, stuck in snow, on soft ground...), it may be advisable to deactivate the ASR and ESP systems, so that the wheels can
move freely and regain grip.  Press the "ESP OFF" button, located on the left below the steering wheel.
If this warning lamp comes on in the instrument panel and the indicator lamp in the button comes on, this indicates that the ASR and ESP systems are deactivated.
Reactivation
These systems are reactivated automatically each time the ignition is switched back on or from 30 mph (50 km/h).  Press the "ESP OFF" button again to
reactivate them manually.
Operating fault
The ESP/ASR systems offer exceptional safety in normal driving, but this should not encourage the driver to take extra risks or drive at high speed. The correct functioning of these systems is assured provided that manufacturer's recommendations are obser ved on: - wheels (tyres and rims), - braking components, - electronic components, - assembly and repair procedures. After an impact, have these systems checked by a CITROËN dealer or a qualified workshop.
If this warning lamp comes on, accompanied by an audible signal and a message in the screen, this
indicates a fault with these systems. Have it checked by a CITROËN dealer or a qualified workshop.

Rear seat belts
Fastening
 Pull the strap, then inser t the tongue in the buckle.  Check that the seat belt is fastened correctly by pulling the strap.
Unfastening
 Press the red button on the buckle.  Guide the seat belt as it reels in.  On the outer seat belts, raise the bar to the top of the backrest to prevent the tongue
from knocking against the side trim.
The rear seats are each fitted with a three-point seat belt, with force limiter and, for the outer seats, an effor t limiter.
Seat belt not fastened/unfastened warning lamps display
1. Driver's seat belt not fastened/unfastened warning lamp. 2. Front passenger’s seat belt not fastened/unfastened warning lamp. The corresponding warning lamp 1 or 2 comes on in red on the seat belt and passenger’s front airbag warning lamps display, accompanied by an audible signal and a message in the multifunction screen, if the seat belt is not fastened or is unfastened.
