Manual gear changing
In the automated mode, you can take over
control temporarily at any time using thesteering mounted controls.
The use of these controls permits manualselection of the gears in situations whichrequire a faster change down than that offered
in automated mode (arrival at a roundabout, exit from a car park with a steep gradient,
over taking...).
The gearbox engages the gear requested if
the engine speed permits it. The gear engaged appears.
To return to the automated mode, do one of thefollowing:
- press the back of the "+/OFF"steering mounted control 3for approximately2 seconds,
- move the gear lever quickly towardsposition +/-
and then return it to position D ,
- stop the vehicle.


Stopping the vehicle
Operating fault

With the ignition on, if the message "Slow

Operating fault

The front parking sensors are triggered when
an obstacle is detected in front, a gear isengaged (position Dfor vehicles with a CVT gearbox) and the speed of the vehicle remains
below 6 mph (10 km/h).
The front parking sensors are interrupted if
the vehicle stops for more than five seconds
in for ward

detected or when the speed of the vehicle
exceeds 6 mph (10 km/h).
Remember to deactivate the system if towing a trailer or caravan.



In bad weather or in winter, ensure thatthe sensors are not covered with mud, ice or snow. When the vehicle is moving at a speed below 6 mph (10 km/h), cer tain soundsources (motorcycle, lorry, pneumatic drill, etc.) may trigger the audible signals of the parking sensor system.
In the event o
f an problem, when reverse gear
is engaged this lamp in the button flashes,
accompanied by an audible signal.This supplements the audiblesignal by displaying bars in the screen, in front of or behind the
vehicle.If one of the sensors is fault

When towing a vehicle with all four wheels on the ground, always use anapproved towing bar; rope and strapsare prohibited.
When towing a vehicle with the engine off, there is no longer any power assistance for braking or steering.
In the following cases, you must always call on a professional recovery service:


- vehicle broken down on a motor way or fast road,

- 4 wheel drive vehicle,

- when it is not possible to put thegearbox into neutral, unlock the steering, or release the parking brake,

- towing with only two wheels on the ground,

- where there is no approved towing bar available...
Towing with the wheels on the groundis only possible on 2 wheel drive (2WD) versions.


Recovery of your vehicle


2 wheel drive (2WD) versions: towingwith the wheels on the ground
)Put the gear lever into neutral (position Nfor the CVT gearbox).)Unlock the steering by by turning the

Par ticle emissions filter (Diesel)

The star t of saturation of the particle filter is
indicated by the temporary illumination of this
warning lamp accompanied by a message in
the instrument panel screen.
As soon as the traffic conditions permit,regenerate the filter by driving at a speed of at least 25 mph (40 km/h) for about 20 minutes (with the 1.6 litre HDiengine the minimum speed is 36 mph(60 km/h)). If the warning lamp stays on, this indicates a low additive level.
On a new vehicle, the first particle filter regeneration operations may be accompanied by a "burning" smell, which is perfectly normal.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 doesnot affect the behaviour of the vehicle or the environment.
