Warning/indicator lampStateCause Action/Observations
STOP Fixed, alone or
associated with
another warning
lamp, accompanied
by an audible signal
and a message in the
screen. Illumination of this warning lamp is
associated with a serious fault with
the braking system, power steering,
engine lubrication system or cooling
system.
Stop as soon as it is safe to do so as there is a risk
that the engine will cut out while driving.
Park, switch off the ignition and call the dealer network
or a qualified workshop.
Maximum
coolant
temperature Fixed.
The temperature of the cooling
system is too high. You must stop as soon as it is safe to do so.
Wait until the engine has cooled down before
topping up the level, if necessary.
If the problem persists, contact the dealer network or
a


qualified workshop.
Engine oil
pressure Fixed.
There is a fault with the engine oil
lubrication circuit. You must stop as soon as it is safe to do so.
Park, switch off the ignition and contact the dealer
network or a qualified workshop.

Compatibility of fuels
Fuel used for petrol engines
The petrol engines are compatible with biofuels
that conform to current and future European
standards and which can be obtained from
filling stations:Petrol that meets standard EN228,
mixed with a biofuel that meets
standard EN15376.
The only petrol additives authorised for
use are those that meet the B715001
standard.
Fuel used for Diesel engines
The Diesel engines are compatible with
biofuels that conform to current and future
European standards and which can be
obtained from filling stations. Diesel fuel that meets standard
EN590 mixed with a biofuel that
meets standard EN14214 (possibly
containing 0 to 7% Fatty Acid Methyl
Ester), For more information, contact the dealer
network or a qualified workshop.Diesel fuel that meets standard
EN16734 mixed with a biofuel that
meets standard EN14214 (possibly
containing 0 to 10% Fatty Acid
Methyl Ester),
Paraffinic Diesel fuel that meets
standard EN15940 mixed with
a biofuel that meets standard
EN14214 (possibly containing 0 to
7% Fatty Acid Methyl Ester).
The use of B20 or B30 fuel meeting
standard EN16709 is possible in
your Diesel engine. However, this
use, even occasional, requires strict
application of the special ser vicing
conditions referred to as "Arduous
conditions".
The use of any other type of (bio)fuel
(vegetable or animal oils, pure or diluted,
domestic fuel...) is strictly prohibited (risk
of damage to the engine and fuel system). The only Diesel additives authorised for
use are those that meet the B715000
standard.
Diesel at low temperature
At temperatures below 0°C (+32°F), the
formation of paraffins in summer-type Diesel
fuels could entail an abnormal operation
of the fuel supply circuit. To avoid this, we
recommend using winter-type Diesel fuel and
keeping the fuel tank more than 50% full.
If, despite this, at temperatures below -15°C
(+5°F) the engine has problems starting,
just leave the vehicle in a garage or heated
workshop for a little while.
Travelling abroad
Certain fuels could damage the engine of your
vehicle.
In certain countries, the use of a particular
fuel may be required (specific octane rating,
specific sales name…) to ensure correct
operation of the engine.
For any additional information, contact the
dealer network.

Topping up the engine oil level
F Locate the oil filler cap in the engine compartment of your vehicle.
For more information about petrol or Diesel
engine, refer to the corresponding section.
F

U
nscrew the oil filler cap to access the filler
opening.
F

A
dd oil in small quantities, avoiding any
spills on engine components (risk of fire).
F

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

A
dd more oil if necessary.
F

A
fter checking the level, carefully refit the oil
filler cap and the dipstick in its tube.
After topping up the oil, the ignition-triggered oil
level indicator in the instrument panel does not
provide a valid information during 30 minutes.
Engine oil change
Refer to the manufacturer's service schedule
for inter val details for this operation.
In order to maintain the reliability of the engine
and emission control system, never use
additives in the engine oil.
Brake fluid level
The brake fluid level should be close
to the "MA X" mark. If it is not, check
the brake pad wear.
Changing the coolant
Refer to the manufacturer's service schedule
for details of the inter val for this operation.
Fluid specification
This fluid must conform to the manufacturer's
recommendations.
Power steering fluid level
The fluid level should be close to
the "MA X" mark. Verify this, with the
engine off, by reading the level on
the filler neck.
Coolant level
Check the coolant level regularly.
It is normal to top up the fluid
between two services. To ensure that the reading is correct, your
vehicle must be parked on a level sur face with
the engine cool.
The coolant level should be close to the "MA X"
mark but should never exceed it.
If the level is close to or below the "MIN" mark,
it is essential to top up.
A low coolant level presents a risk of serious
damage to your engine.
When the engine is warm, the temperature of
the coolant is regulated by the fan.
In addition, as the cooling system is pressurised,
wait at least one hour after switching off the
engine before carrying out any work.
To avoid the risk of scalding when you need to
top up in an emergency, place 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 the level.
The cooling fan may star t after
switching off the engine: take care
with articles and clothing that might be
caught by the fan blades.
Fluid specification
The brake fluid must conform to the
manufacturer's recommendations.
