Ease of use and comfort03
When the USB socket is used, the portable
device charges automatically.
While charging, a message is displayed if the
power drawn by the portable device exceeds
the current supplied by the vehicle.
For more information about how to use this
equipment, refer to the sections describing the
audio and telematics systems.
Storage compartment

►  To open the storage compartment, press the
front central part.
Wireless smartphone charger



This system allows wireless charging of a
portable device such as a smartphone, using the
magnetic induction principle, in accordance with
the Qi 1.1 standard.
The portable device to be charged must be
compatible with the Qi standard, either by design
or by using a compatible holder or shell.
A mat can also be used provided that it is
approved by the Manufacturer.
The charging area is identified by the Qi symbol.
The charger works with the engine running and
with the Stop & Start system in STOP mode.
Charging is managed by the smartphone.
With the Keyless Entry and Start system, the
charger’s operation may be briefly disrupted when
a door is opened or the ignition is switched off.
Charging
►  With the charging area clear, place a device in
its centre.


When the portable device is detected, the
charger’s indicator lamp lights up green. It
remains lit for the whole time that the battery is
being charged.
The system is not designed to charge
multiple devices simultaneously.
Do not leave metal objects (e.g. coins,
keys, vehicle remote control) in the
charging area while a device is being charged
- Risk of overheating or interrupting the
charging!
When using applications for a long time in
combination with wireless charging, some
smartphones may switch to thermal safety
and cause some functions to stop.
Checking operation
The state of the indicator lamp allows the
operation of the charger to be monitored.

Driving recommendations
► Observe the driving regulations and remain
vigilant whatever the traffic conditions.
►  Monitor your environment and keep your
hands on the wheel to be able to react to anything
that may happen any time.
►  Drive smoothly, anticipate the need for braking
and maintain a longer safety distance, especially
in bad weather.
►  Stop the vehicle before performing operations
that require sustained attention (e.g. settings).
►  During long trips, take a break every 2 hours.
Important!
Never leave the engine running in a closed
space without sufficient ventilation.
Internal combustion engines emit toxic
exhaust gases such as carbon monoxide.
Danger of poisoning and death!
In very severe wintry conditions
(temperature below -23°C), let the engine
run for 4 minutes before moving off, to ensure
the correct operation and durability of the
mechanical components of your vehicle
(engine and gearbox).
Never drive with the parking brake
applied. Risk of overheating and
damaging the braking system!
Never park the vehicle and never leave the
engine running on a flammable surface
(e.g. dry grass, dead leaves).The vehicle
exhaust system is very hot, even several
minutes after the engine stops. Risk of fire!
Never drive on surfaces covered with
vegetation (e.g. tall grass, accumulated
dead leaves, crops, debris) such as a field, a
country lane overgrown with bushes or a
grassy verge.
This vegetation could come into contact with
the vehicle's exhaust system or other systems
which are very hot. Risk of fire!
Make sure you do not leave any item in the
passenger compartment which could act
like a magnifying glass under the effect of the
sun's rays and cause a fire. Risk of fire or
damage to interior surfaces!
Never leave the vehicle unattended, with
the engine running. If you have to leave
your vehicle with the engine running, apply the
parking brake and put the automatic gearbox
into position N or P.
Never leave children inside the vehicle
unsupervised.

Repeated hard braking in this vehicle
can generate loud banging noises which are
completely normal.
Continue driving but with lighter braking so
that the braking system can cool down.
The performance of the braking system
remains unaffected.
On flooded roads
We strongly advise against driving on flooded
roads, as this could cause serious damage to the
internal combustion engine or electric motor, the
gearbox and the electrical systems of the vehicle.


If the vehicle absolutely must drive through a
flooded section of road:
►  Check that the depth of the water does not
exceed 15 cm, taking account of waves that might
be generated by other users.
►  Deactivate the Stop & Start function.
►  For rechargeable hybrid engines, place the
mode selector in 4WD position (depending on
version).
►  Drive as slowly as possible without stalling. In
all cases, do not exceed 6 mph (10 km/h).

97Driving06
► Do not stop and do not switch off the engine.
On leaving the flooded road, as soon as safety
conditions allow, make several light brake
applications to dry the brake discs and pads.
If in doubt about the state of your vehicle, contact
a dealer or a qualified workshop.
Towing
Driving with a trailer places greater
demands on the towing vehicle and
particular care must be taken.
Do not exceed the maximum towable
weights.
At altitude: reduce the maximum load by 10%
per 1,000 metres of altitude; the lower air
density at high altitudes decreases engine
performance.
New vehicle: do not tow a trailer until the
vehicle has driven at least 620 miles
(1,000 kilometres).
If the outside temperature is high, let the
engine idle for 1 to 2 minutes after the
vehicle comes to a stop, to help it to cool.
Before setting off
Nose weight
►  Distribute the load in the trailer so that the
heaviest items are as close as possible to the axle
and the nose weight (at the point where it joins
your vehicle) approaches the maximum permitted
without exceeding it.
Tyres
►  Check the tyre pressures of the towing vehicle
and of the trailer, observing the recommended
pressures.
Lighting
►  Check the electrical signalling on the trailer
and the headlamp beam height of your vehicle.
If a genuine towing device is used, the
rear parking sensors will be deactivated
automatically to avoid the audible signal.
When driving
Cooling
Towing a trailer uphill causes the coolant
temperature to increase. The maximum towable
load depends on the gradient and the exterior
temperature. The fan’s cooling capacity does not
increase with engine speed.
►  Reduce speed and lower the engine speed to
limit the amount of heating produced.
►  Pay constant attention to the coolant
temperature.
If this warning lamp and the STOP
warning lamp come on, stop the
vehicle and switch off the engine as soon as
possible.
Brakes
Using the engine brake is recommended to limit
the overheating of the brakes. Braking distances
are increased when towing a trailer.
Side wind
Bear in mind that the vehicle will be more
susceptible to wind when towing.
Anti-theft protection
Electronic immobiliser
The keys contain a code, which must be
recognised by the vehicle before starting is
possible.
If the system malfunctions, indicated by the
display of a message, the engine will not start.
Contact a dealer.
Starting/switching off the
engine
The electronic key must be present in the
passenger compartment.
If the electronic key is not detected, a message
is displayed.
