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.

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.

Front airbags
System which protects the driver and front passenger in the event of a serious front impact in order to limit the risk of injury to the head and thorax. The driver's airbag is fitted in the centre of the steering wheel; the front passenger's airbag is fitted in the dashboard above the glove box.
Deployment
The airbags are deployed simultaneously, unless the passenger's front airbag is deactivated, in the event of a serious front impact to all or par t of the front impact zone A , in the longitudinal centreline of the vehicle on a horizontal plane and directed from the front to the rear of the vehicle.
The front airbag inflates between the thorax and head of the front occupant of the vehicle and the steering wheel, driver's side, and the
dashboard, passenger's side to cushion their for ward movement.

For the airbags to be fully effective, observe the following safety rules:
Front airbags
Do not drive holding the steering wheel by its spokes or resting your hands on the centre par t of the wheel.
Passengers must not place their feet on the dashboard. If possible, do not smoke as deployment of the airbags can cause burns or the risk of injury from a cigarette or pipe. Never remove or pierce the steering wheel or hit it violently.
Lateral airbags
Use only approved covers on the seats, compatible with the deployment the lateral airbags. For information on the range of seat covers suitable for your vehicle, you can contact a CITROËN dealer (see "Practical information - § Accessories"). Do not fix or attach anything to the seat backs (clothing...). This could cause injury to the chest or arms if the lateral airbag is deployed. Do not sit with the upper par t of the body any nearer to the door than necessary.
Curtain airbags
Do not fix or attach anything to the roof. This could cause injury to the head if the cur tain airbag is deployed.
Do not remove the grab handles installed on the roof, they play a par t in securing the cur tain airbags.
Sit in a normal upright position. Wear a correctly adjusted seat belt. Do not leave anything between the occupants and the airbags (a child, pet, object...). This could hamper the operation of the airbags or injure the occupants. After an accident or if the vehicle has been stolen or broken into, have the airbag systems checked. All work on the airbag system must be carried out by a CITROËN dealer or a qualified workshop. Even if all of the precautions mentioned are obser ved, a risk of injury or of minor burns to the head, chest or arms when an airbag is deployed cannot be ruled out. The
bag inflates almost instantly (within a few milliseconds) then deflates within the same time discharging the hot gas via openings provided for this purpose.

201Driving
Six-speed electronic gearbox system which offers a choice between the comfor t of fully automatic operation or the pleasure of manual gear changing. There are two driving modes:
- automatic mode for automatic control of the gears by the gearbox, - manual mode for sequential gear changing by the driver. In automatic mode, it remains possible to change gear manually by using the steering mounted control paddles, when over taking, for example.
6-speed electronic gearbox system
R. Reverse  With your foot on the brake, lift the lever and push for wards. N. Neutral.
 With your foot on the brake, select this position to star t. A. Automatic mode.
 Move the lever backwards to select this mode. M. Manual mode with sequential gear changing.  Move the lever backwards then to the left to select this mode, then use the steering mounted control paddles to change gear.
Gear lever
+. Change up paddle to the right of the steering wheel.  Press the back of the "+" steering mounted paddle to change up a gear.
-. Change down paddle to the left of the steering wheel.  Press the back of the "-" steering mounted
paddle to change down a gear.
Steering mounted control paddles
The steering mounted paddles cannot be used to select neutral or to engage or disengage reverse gear.

203Driving
For optimum acceleration, for example
when over taking another vehicle, press the accelerator pedal firmly past the point of resistance.
Manual gear changing
This selective gear change mode enables you to over take, for example, while still remaining in automatic mode.  Operate the + or - steering mounted control paddle. The gearbox engages the gear requested if the engine speed permits. AUTO is still displayed in the instrument panel. After a few moments without any action on the controls, the gearbox resumes automatic control of the gears.
Manual mode
 After star ting the vehicle, select position Afor enter automatic mode.
Automatic mode
AUTO and the gear engaged appear in the instrument panel screen.
The gearbox is then operating in auto-active mode, without any action on the par t of the driver. It continuously selects the most suitable gear, depending on the: - style of driving, - profile of the road.
 When the vehicle has moved off, select position M to change to manual mode.
AUTO disappears and the gears engaged appear in succession in the instrument panel screen.
The gear change requests are only carried out if the engine speed permits. It is not necessary to release the accelerator during gear changes. When braking or slowing down, the gearbox changes down automatically to allow the vehicle to accelerate in the correct gear.
At very low speed, if reverse gear is requested, this will only be taken into account when the vehicle is immobilised. The Foot on brakewarning lamp may flash in the instrument panel to prompt you to brake.
On sharp acceleration, the gearbox will not change up unless the driver acts on the gear lever or the steering mounted paddles. Never select neutral N while the vehicle
is moving. Only engage reverse gear R when the vehicle is immobilised with the brake pedal pressed.
