sharp acceleration, the speed limiter will
not be able to prevent the vehicle from

your vehicle.
Once the speed of the vehicle returns to the
programmed setting, the speed limiter functions

Cruise control - particular
recommendations
For the safety of everyone, only use the
cruise control where the driving
conditions allow running at a constant speed
and keeping an adequate safety distance.
Remain vigilant when the cruise control
is activated. If you hold one of the speed
setting modification buttons down, a very
rapid change in the speed of your vehicle may
occur.
When descending a steep hill , the cruise
control system cannot prevent the vehicle
from exceeding the set speed. Brake if
necessary to control the speed of your
vehicle.
On steep climbs or when towing, the set
speed may not be reached or maintained.
Exceeding the programmed speed
setting
You can temporarily exceed the speed
setting by pressing the accelerator pedal (the
programmed speed flashes).
To return to the speed setting, release the
accelerator pedal (when the set speed is
reached again, the displayed speed stops
flashing).
Operating limits
Never use the system in the following
situations:
– In an urban area with the risk of pedestrians crossing the road.– In heavy traffic.– On winding or steep roads.– On slippery or flooded roads.– In poor weather conditions.– Driving on a speed circuit.– Driving on a rolling road.– When using snow chains, non-slip covers or studded tyres.
Cruise control
Refer to the General recommendations on the
use of driving and manoeuvring aids and to
Cruise control - particular recommendations.
This system automatically keeps the vehicle’s speed at the cruise value
programmed by the driver (speed setting), without using the accelerator pedal.
The cruise control is switched on manually.
It requires a minimum vehicle speed of 25 mph
(40 km/h).With a manual gearbox, third gear or higher must
be engaged.
With an automatic gearbox, mode D or second gear or higher in mode M must be engaged.
The cruise control remains active after changing gear, regardless of the gearbox
type, on engines fitted with Stop & Start.
Switching off the ignition cancels any
speed setting.

Bluetooth® audio system
Bluetooth® audio system

The different functions and settings described vary according to the version
and configuration of your vehicle.
As a safety measure and because it requires sustained attention by the driver,
the pairing of a Bluetooth mobile telephone
with the Bluetooth hands-free system of your
audio system must be done with the vehicle
stationary and the ignition on.
Your audio system is coded in such a way that it will only operate in your
vehicle.
All work on the system must be carried out
exclusively by a dealer or qualified workshop,
to avoid any risk of electrocution, fire or
mechanical faults.
To avoid discharging the battery, the audio system may switch off after a few
minutes if the engine is not running.
