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.
Seat belt not
fastened/
unfastened *Fixed, then flashing,
accompanied by an
increasing audible
signal. The driver or front passenger has
not fastened or has unfastened their
seat belt.
At least one rear passenger has
unfastened their seat belt. Pull on the belt in question and insert the tongue in the
buckle.
This warning repeats the seat belt information given by
the roof console warning lamps.

In case of towing
Driving with a trailer places greater
demands on the towing vehicle and
requires extra care from the driver.
Distribution of loads
F Distribute the load in the trailer so that the heaviest items are as close as possible to
the axle and the nose weight approaches
the maximum permitted without exceeding
it.
Air density decreases with altitude, thus
reducing engine performance. The maximum
towed load must be reduced by 10% for every
1,000 metres of altitude.
For more information on the Technical
data of your vehicle and particularly on
towable loads, refer to the corresponding
section.
If the exterior temperature is high, it is
recommended that the engine be allowed
to idle for 1 to 2 minutes after the vehicle
comes to a stop, to facilitate its cooling.
Side wind
F Take into account the increased sensitivity to wind.
Cooling
Towing a trailer on a slope increases the
temperature of the coolant.
As the fan is electrically controlled, its cooling
capacity is not dependent on the engine speed.
F

T
o lower the engine speed, reduce your
speed.
The maximum towed load on a long incline
depends on the gradient and the exterior
temperature.
In all cases, keep a check on the coolant
temperature.
F

I
f this warning lamp and the
STOP warning lamp come on,
stop the vehicle and switch off
the engine as soon as possible.
Braking
Towing a trailer increases the braking distance.
To avoid overheating of the brakes, the use of
engine braking is recommended.
Ty r e s
F Check the tyre pressures of the towing vehicle and of the trailer, observing the
recommended pressures.
Lighting
F Check the electrical lighting and signalling on the trailer and the headlamp beam height
of your vehicle.
For more information on Headlamp
adjustment , refer to the corresponding
section.
The rear parking sensors will be
deactivated automatically to avoid
the audible signal if a genuine DS
AUTOMOBILES towbar is used.

The location of the interior bonnet release
lever prevents opening of the bonnet when
the left-hand front door is shut.
Do not open the bonnet when there is a
very strong wind.
When the engine is hot, handle the
exterior safety catch and the stay with
care (risk of burns).
Closing
F Take the stay out of the support slot.
F C lip the stay in its housing on the back of
the bonnet.

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

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.
