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.The warning lamp lighting up is
associated with a serious fault in the
brakes or the coolant temperature. 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 contact the dealer
network or a
qualified workshop.
Parking brake Fixed. The parking brake is applied or not
properly released. Release the parking brake to switch off the warning
lamp, keeping your foot on the brake pedal.
Observe the safety recommendations.
For more information on the Parking brake
, refer to
the corresponding section.
+ Brakes
Fixed, associated
with the STOP
warning lamp. The brake fluid level in the braking
circuit is too low.
You must stop as soon as it is safe to do so.
Top up with brake fluid that complies with the
manufacturer's recommendations.
If the problem persists, have the system checked in
the dealer network or by a
qualified workshop.
+
+ Fixed, associated
with the STOP and
ABS warning lamps.
The electronic brake force
distribution (EBFD) system is faulty.
You must stop as soon as it is safe to do so.
Have it checked by a
dealer or by a qualified
workshop.

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.
Battery charge Fixed. The battery charging circuit has
a
fault (dirty or loose terminals, slack
or cut alternator belt, etc.). The warning lamp should go off when the engine is
started.
If it does not go off, contact the dealer network or
a


qualified workshop.
Door(s) open
Fixed, if the speed is
below 6 mph (10 km/h).A door or the boot is still open. Close the door or boot.
Fixed and accompanied

6
mph (10 km/h).

In case of towing
Driving with a trailer places greater
d emands 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.
Please respect the maximum towable
weights.
Side wind
F Take into account the increased sensitivity to wind.
Cooling
Towing a trailer on a slope increases the
t emperature 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 towable load on an 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.
New vehicle
Do not pull a trailer before having driven at least
approximately 600


miles (1,000

kilometres).
Braking
Towing a trailer increases the braking distance.
T o 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
beam height 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.
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.

A = MA X
B = MIN
If you find that the level is above the A mark or
below the B mark, do not star t the engine.
-

I

f the level is above the MAX mark (risk of
damage to the engine), contact the dealer
network or a

qualified workshop.
-

I

f the level is below the MIN mark, you must
top up the engine oil.
Topping up the engine oil level
The location of the oil filler cap is shown in the
corresponding underbonnet layout view. After topping up the oil, the check
per formed by the oil level indicator in
the instrument panel when the ignition
is switched on is not valid during the
30
minutes after topping up.
Engine oil change
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 fl
uid
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.
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.

Oil grade
Before topping up the oil or changing the oil,
check that the oil is the correct grade for your
engine and conforms to the manufacturer's
recommendations.
In addition, with the engine hot and as the
cooling system is pressurised, wait at least
one hour after switching off the engine before
carrying out any work.
