137Safety
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 on the instrument panel.

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 on 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) (except 1.6 litreTHP 150 petrol engine).
 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 depends on obser vation of the manufacturer's recommendations regarding the wheels (tyres and rims), the braking components, the electronic components and the CITROËN assembly and operation procedures. After an impact, have these systems checked by a CITROËN dealer.
If this warning lamp comes on, accompanied by an audible signal and a message on the multifunction screen, this
indicates a malfunction of these systems. Have the systems checked by a CITROËN dealer.

6-speed manual gearbox
 Raise the ring under the knob and push the gear lever to the left then for wards.
Engaging reverse gear
As a safety precaution and to facilitate star ting of the engine: - always select neutral, - press the clutch pedal.
Only engage reverse gear when the vehicle is stationary with the engine at idle.

Gear shift indicator *
Operation
The system inter venes only when driving economically.
Depending on the driving situation and your vehicle's equipment, the system may advise you to skip one or more gears. You can follow this instruction without engaging the intermediate gears. The gear engagement recommendations must not be considered compulsory. In fact, the configuration of the road, the amount of traffic and safety remain determining factors when choosing the best gear. Therefore, the driver remains responsible for deciding whether or not to follow the advice given by the system. This function cannot be deactivated.
- The system may suggest that you engage a higher gear, if appropriate.
The information appears in the instrument panel screen in the form of an arrow accompanied by the suggested gear.
In the case of driving which makes par ticular demands on the per formance of the engine (firm pressure on the accelerator pedal, for example, when over taking...), the system will not recommend a gear change. The system never suggests: - engaging first gear, - engaging reverse gear, - engaging a lower gear.
* According to engine.
Example:
- You are in third gear.
- You press the accelerator pedal moderately.

153Driving
Four-speed automatic gearbox which offers a choice between the comfor t of fully automatic operation, enhanced by spor t and snow programmes, or manual gear changing. Therefore, four driving modes are offered:
- automatic operation for electronic management of the gears by the gearbox, - spor t programme for a more dynamic style of driving, - snow programme to improve driving when traction is poor, - manual operation for sequential changing of the gears by the driver.

Foot on brake
Press the brake pedal when this indicator lamp is displayed on the instrument panel (e.g.: star ting the engine).
Moving off
If position N is engaged inadver tently while driving, allow the engine to return to idle then engage position D to accelerate.
When the engine is running at idle, with the brakes released, if position R ,
D or M is selected, the vehicle moves even without the accelerator being pressed. When the engine is running, never leave children in the vehicle without super vision. When carrying out maintenance with the engine running, apply the parking brake and select position P . PP
 Apply the parking brake.  Select position P or N .  Star t the engine. If this procedure is not followed, an audible signal is heard, accompanied by a message on the multifunction screen.  With the engine running, press the brake pedal.  Release the parking brake.  Select position R , D or M ,  Gradually release the brake pedal. The vehicle moves off immediately.
