Dashboard instruments
1On versions fitted with an electric gauge, the
engine oil level status is displayed on the
instrument panel for a few seconds when
the ignition is switched on, after the servicing
information, in the form of messages.
The level read will only be correct if the vehicle is on level ground and the engine
has been off for more than 30 minutes.
Low oil level
This is indicated by a message prompting you to
top up the level, accompanied by the lighting of
the Service warning lamp and an audible signal.
If a low oil level is confirmed by a check using
the dipstick, the level must be topped up to avoid
damage to the engine.
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.
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.

Practical information
7Opening



► From the inside: pull the control lever ,
located on the left below the dashboard, towards
you.


► From the outside: lift the safety catch and
raise the bonnet.
T
wo bonnet struts open the bonnet and hold it
open.
Closing
► 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
The engine shown here is an example for
illustrative purposes only.
The locations of the following components may
vary:
–

Air filter
.
–

Engine oil dipstick.
–


Engine oil filler cap.
Petrol engine

1. Screenwash fluid reservoir
2. Engine coolant reservoir
3. Brake fluid reservoir
4. Battery/Fuses
5. Remote earth point (-)
6. Fusebox
7. Air filter
8. Engine oil filler cap
9. Engine oil dipstick
Diesel fuel system
This system is under very high pressure.
All work must be carried out only by a
PEUGEOT dealer or a qualified workshop
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.
The fluids must comply with the Manufacturer's requirements and with
the vehicle's engine.
Take care when working under the bonnet, as certain areas of the engine
may be extremely hot (risk of burns) and the

165
Practical information
7Engine 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.
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.
Otherwise, have them checked by a PEUGEOT
dealer or a qualified workshop.
Only use products recommended by
PEUGEOT or products of equivalent
quality and specification.
In order to optimise the operation of
components as important as those in the
braking system, PEUGEOT selects and offers
very specific products.
12 V battery
The battery does not require any maintenance.
Check regularly that the terminals are correctly
tightened (versions without quick-release
terminals) and that the connections are clean.
For more information on the precautions
to take before any work on the 12 V
battery, refer to the corresponding section.
