Dashboard instruments
1In the event of a malfunction of the
electric gauge, the oil level is no longer
monitored.
If the system is faulty, you must check the
engine oil level using the manual dipstick
located in the engine compartment.
For more information on Checking levels,
refer to the corresponding section.
Coolant temperature
indicator


With the engine running:
– In zone A, the temperature is correct.
–

In zone
B, the temperature is too high. The
associated warning lamp and the STOP
warning
lamp light up in red on the instrument panel,
accompanied by the display of a message and
an audible signal.
You must stop the vehicle as soon as it is
safe to do so.
Wait a few minutes before switching off the
engine.
After switching off the ignition, carefully open the bonnet and check the coolant
level.
For more information on Checking
levels, refer to the corresponding
section.
AdBlue® range indicators
(BlueHDi)
The Diesel BlueHDi engines are equipped with
a system that associates the SCR (Selective
Catalytic Reduction) emissions control system
and the Diesel particle filter (DPF) for the
treatment of exhaust gases. They cannot
function without AdBlue
® fluid.
When the level of AdBlue® falls below the
reserve level (between 1,500 and 0 miles (2,400
and 0

km)), a warning lamp lights up when
the ignition is switched on and an estimate
of the distance that can be travelled before
engine starting is prevented is displayed in the
instrument panel.
The engine starting prevention system required by regulations is activated
automatically once the AdBlue
® tank is empty.
It is then no longer possible to start the
engine until the minimum level of AdBlue
® has
been topped up.
Manual display of driving range
While the driving range is greater than
1,500 miles (2,400 km), it is not displayed
automatically.
Driving range information is accessible
using the Settings > Vehicle application
on the touch screen.
►

Then select
Safety > Diagnostics.
Actions required related to a lack of AdBlue®
The following warning lamps light up when the
quantity of AdBlue® is below the reserve level:
driving range of 1,500 miles (2,400 km).
Together with the warning lamps, messages
regularly remind you of the need to top up to
avoid engine starting being prevented. Refer to
the Warning and indicator lamps section for
details of the messages displayed.
For more information on AdBlue®
(BlueHDi) and in particular on topping
up, refer to the corresponding section.

Driving
6Noise (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.
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:
–

T
raction battery 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 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.
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 PEUGEOT towing device is
used, the rear parking sensors will be
deactivated automatically to avoid activating
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.

Practical information
7Closing
► Lower the bonnet and release it near the end
of its travel.
►

Check the locking.
Because of the presence of electrical
equipment under the bonnet, it is strongly
recommended that exposure to water (rain,
washing, etc.) be limited.
Engine compartment

illustrative purposes only.

Checking levels
Check all of the following levels regularly in
accordance with the Manufacturer's service
schedule. Top them up if required, unless
otherwise indicated.
If a level drops significantly, have the
corresponding system checked by a PEUGEOT
dealer or a qualified workshop.

191
Practical information
7Brake fluid
The level of this fluid should be close to the "MAX" mark. If not, check the brake
pads for wear.
To know how often the brake fluid should be
replaced, refer to the manufacturer's servicing
schedule.
Clean the cap before removing it to refill.
Use only DOT4 brake fluid from a sealed
container.
Engine coolant
For petrol, Diesel, hybrid or rechargeable
hybrid versions
It is normal to top up this fluid between
two services.
The check and top-up must only be done with
the engine cold.
A level of coolant that is too low risks causing
major damage to the engine; the coolant level
must be close to the "MAX" mark without ever
going above it.
If the level is close to or below the " MIN" mark, it
is essential to top it up.
When the engine is hot, the temperature of the
coolant is regulated by the fan.
As the cooling system is pressurised, wait at
least one hour after switching off the engine
before carrying out any work.
In order to avoid the risk of scalding if you need
to top up in an emergency, wrap a cloth around
the cap and unscrew the cap by two turns to
allow the pressure to drop.
Once the pressure has dropped, remove the cap
and top up to the required level.
For electric versionsDo not top up the coolant.
If the level is close to or below
the "MIN" mark, it is essential to contact a
PEUGEOT dealer or a qualified workshop.
Screenwash fluid
Top up to the required level when necessary.
Fluid specification
The fluid must be topped up with a pre-mixed
product.
In winter (temperatures below zero), a fluid
containing an anti-freeze agent which is
appropriate for the temperature conditions
must be used in order to protect the system's
components (pump, tank, ducts, jets).
Filling with pure water is prohibited in all
circumstances (risk of freezing,
limescale, etc.).
Diesel fuel additive (Diesel
with particle filter)
On reaching the minimum level in the
particle filter additive tank, this warning
lamp comes on fixed, accompanied by an
audible signal and a warning message.
Topping up
The topping up of this additive must be carried
out quickly.
Go to a PEUGEOT dealer or a qualified
workshop.
AdBlue® (BlueHDi)
An alert is triggered when the reserve level is
reached.
For more information on the Indicators and in
particular the AdBlue range indicators, refer to
the corresponding section.
To avoid the vehicle being immobilised in
accordance with regulations, you must top up the
AdBlue tank.
For more information on AdBlue
® (BlueHDi),
and in particular the supply of AdBlue, refer to
the corresponding section.
Checks
Unless otherwise indicated, check these
components in accordance with the
Manufacturer's service schedule and according
to your engine.
