Driving recommendations  
vehicle.

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.  
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!  
If the vehicle absolutely must drive through a  
flooded section of road:  
Stop the vehicle before performing  
operations that require sustained attention  
(e.g. settings).  
Check that the depth of the water does not  
exceed 15 cm, taking account of waves that  
might be generated by other users.  
During long trips, take a break every 2 hours.  
Deactivate the Stop & Start function.  
Drive as slowly as possible without stalling. In  
all cases, do not exceed 6 mph (10 km/h).  
Important!  
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 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!  
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 PEUGEOT dealer or a qualified  
workshop.  
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 gearbox  
or drive selector into neutral or position N or P  
(depending on version).  
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).  
Noise (Electric)  
On the outside  
Due to the vehicle’s quiet operation when  
driving, the driver must pay particular attention.  
When manoeuvring, the driver must always  
check the vehicle's immediate surroundings.  
At speeds of up to 19 mph (30 km/h), the  
pedestrian horn warns other road users of the  
vehicle’s presence.  
Never leave children inside the vehicle  
unsupervised.  
Never drive with the parking brake  
applied. Risk of overheating and  
damaging the braking system!  
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,

Driving  
Before setting off  
Nose weight  
If this warning lamp and the STOP  
warning lamp come on, stop the  
vehicle and switch off the engine as  
soon as possible.  
Cooling the traction battery The cooling  
fan comes on during charging to cool the  
on-board charger and the traction battery.  
Distribute the load in the trailer so that  
the heaviest items are located 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.  
On the inside  
During use, you may hear certain perfectly  
normal noises specific to electric vehicles, such  
as:  
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.  
Tyres  
Traction battery relay when starting.  
Vacuum pump when braking.  
Check the tyre pressures of the towing  
vehicle and of the trailer, observing the  
recommended pressures.  
Vehicle tyres or aerodynamics when driving.  
Jolting and knocking noise during hill starts.  
Lighting  
Check the electrical signalling on the trailer  
and the headlamp beam height of your  
vehicle.  
Anti-theft protection  
Towing  
Electronic immobiliser  
Driving with a trailer places greater  
demands on the towing vehicle and  
particular care must be taken.  
If a genuine PEUGEOT towing device is  
used, the rear parking sensors will be  
deactivated automatically to avoid activating  
the audible signal.  
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 PEUGEOT dealer.  
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.  
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.  
New vehicle: do not tow a trailer until  
the vehicle has driven at least 620 miles  
(1,000 kilometres).  
Reduce speed and lower the engine speed to  
limit the amount of heating produced.  
Pay constant attention to the coolant  
temperature.  
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.
