Dashboard instruments
Driver information
Instrument panel
The instrument panel displays all the information
the driver needs about the status of the vehicle's
various systems.
This information appears in the form of warning
and indicator lamps and messages.
The instrument panel is in the form of a fully
digital screen.
Digital instrument panels
Digital instrument panels are of the head-up or
3D head-up type.
They can be personalised using a system of
pages and widgets.
Depending on the page displayed, certain
information is not displayed or is presented
differently.

Information displayed on
the instrument panel
The information displayed on the instrument
panel (e.g. warning lamps, indicators) may have
a fixed or variable location depending on the
page or the driving aid activated.
For the functions that have indicator lamps for
both operation and deactivation, there is only
one dedicated location.
Display language and units
These depend on the touch screen
settings.
When travelling abroad, the speed must be
shown in the official units of the country you
are driving in (mph, miles or km/h, km).
Choice of the displayed page
By default, pages are memorised in the
instrument panel.

For more information on Checking levels, refer
to the corresponding section.
Oil gauge malfunction
This is indicated by the message " Oil level
measurement invalid" on the instrument panel.
Consult a PEUGEOT dealer or a qualified
workshop.
In 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.
Power indicator
(Rechargeable hybrid)
The power indicator shows in real time the power demanded from the vehicle.
There are 3 zones:


POWER High power demand, using the combined capabilities of the petrol
engine and the electric motor.
The slider is located in this zone
during more dynamic driving phases
when high levels of performance are
being demanded.
ECO Optimal use of energy (internal combustion or electric).
The slider is located in this zone
when driving under electric power
and when optimal use is being made
of the petrol engine, both accessible
by adopting a suitable driving style.
A symbol indicates the threshold at
which the petrol engine will restart.
The driver can therefore moderate
their acceleration to remain in electric
driving mode.
CHARGE Energy recovery for partly recharging the traction battery.
The slider is located in this zone
during deceleration: taking your foot
off the accelerator pedal or braking. CarM an uals 2 .c o m

Driving
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 PEUGEOT 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 PEUGEOT dealer.
Starting/switching off the
engine
The electronic key must be present in the passenger compartment.
The electronic key is also detected in the
boot.
If the electronic key is not detected, a
message is displayed.
Move the electronic key so that the engine
can be started or switched off. CarM an uals 2 .c o m

Practical information
In order to maintain the reliability of the
engine and emissions control system,
never use additives in the engine oil.
Checking using the dipstick
For the location of the dipstick, please refer
to the illustration of the corresponding engine
compartment.
►

Grasp the dipstick by its coloured grip and
pull it out completely

.
►

Wipe the end of the dipstick using a clean,
lint-free cloth.


► Reinsert the dipstick and push fully down,
then pull it out again to visually check the oil
level: the correct level is between marks A
(max)
and B (min).
Do not start the engine if the level is:
–

above mark
A: contact a PEUGEOT dealer or
a qualified workshop.
–

below mark B

: top up the engine oil
immediately.
Oil grade
Before topping up or changing the
engine oil, check that the oil is suitable
for your engine and complies with the
recommendations in the service schedule
supplied with the vehicle (or available
from your PEUGEOT dealer or qualified
workshop).
Use of non-recommended oil may invalidate
your warranty in the event of engine failure.
Topping up the engine oil level
For the location of the engine oil filler cap, please
refer to the corresponding engine compartment
illustration.
►

Add oil in small quantities, avoiding any spills
on engine components (risk of fire).
►


W
ait a few minutes before checking the level
again using the dipstick.
►

T
op up the level if necessary.
►

After checking the level, carefully screw the
oil filler cap back on

and replace the dipstick in
its tube.
The oil level indication displayed on the instrument panel when the ignition is
switched on is not valid for 30 minutes
following an addition of oil.
Brake 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
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.
Screenwash fluid
Top up to the required level when necessary. CarM an uals 2 .c o m
