Thermal comfort consumption
indicator (Electric)


The gauge shows the consumption of electric
power for thermal comfort functions.
It concerns the following equipment and systems:
– Heating.
–

Air c
onditioning.
–

F
ront demisting/defrosting.
–

R
ear screen demisting/defrosting.
–

Hea
ted seats.
The traction battery powers the heating and air
conditioning systems.
This equipment and these functions can be used:
–

If the v
ehicle is not plugged in, when the READY
lamp is lit.
–

If the v
ehicle is plugged in, when the ignition is
switched on.
Selecting Eco mode limits the performance of
some equipment. The cursor on the thermal
comfort consumption indicator then moves into
the "ECO" zone.
To quickly heat or cool the passenger
compartment, feel free to temporarily
select the maximum heating or cooling setting.
Excessive use of thermal comfort equipment,
particularly at low speed, can significantly
decrease the vehicle's range.
Remember to optimise equipment settings
upon achieving the desired level of comfort,
and adjust them if necessary whenever you
start the vehicle.
After an extended period without using the
heating, you may notice a slight odour during
the first few minutes of use.

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 to carry out operations that
require close attention (such as adjustments).
►  During long trips, take a break every two
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 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 damage
to the braking system!
Do not park the vehicle or leave the engine
running on a flammable surface (dry
grass, dead leaves, etc.). The exhaust system
of your vehicle is very hot, even several
minutes after the engine stops. Risk of fire!
Never leave a vehicle unattended with the
engine running. If you have to leave your
vehicle with the engine running, apply the
parking brake and put the gearbox into neutral
or position N or P (depending on the type of
gearbox).
Never leave children inside the vehicle
unsupervised.
On flooded roads
We strongly advise against driving on flooded
roads, as this could cause serious damage to the
engine or gearbox, as well as to the electrical
systems of your vehicle.


If you are obliged to drive on a flooded road:
►  check that the depth of water does not exceed
15 cm, taking account of waves that might be
generated by other users,
►  deactivate the Stop & Start function,
►  drive as slowly as possible without stalling. In
all cases, do not exceed 6 mph (10 km/h),
►  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.
Noise (Electric)
On the outside
Due to the vehicle’s quiet operation when driving,
the driver should pay particular attention.
At speeds of up to 19 mph (30 km/h), the
pedestrian horn warns other road users of the
vehicle’s presence.
Cooling the traction battery
The cooling fan comes on during charging
to cool the on-board charger and the traction
battery.
On the inside
During use, you may hear certain perfectly normal
noises specific to electric vehicles, such as:
–

Traction ba
ttery relay when starting.
–

V
acuum pump when braking.
–

V
ehicle tyres or aerodynamics when driving.
– Jolting and knocking noise during hill starts.
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 heating up.
In all cases, pay 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
Braking distances are increased when towing a
trailer. To avoid overheating the brakes, the use of
engine braking is recommended.
Side wind
Bear in mind that the vehicle will be more
susceptible to wind when towing.
Anti-theft protection
Electronic immobiliser
The keys include an electronic engine immobiliser
system, with a code that must be recognised in
order for starting to be 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.
For versions equipped with Proximity Keyless
Entry and Start, the electronic key is also
detected in the boot.
If it is not detected, a message is displayed.
Move the electronic key so that the engine can
be started or switched off.
If there is still a problem, refer to the "Key not
detected - Back-up starting or Back-up switch-
off" section.
