check engine light Citroen DS4 2012 1.G Owner's Manual

Limit the causes of excess
consumption
Spread loads throughout the vehicle; placethe heaviest items in the bottom of the boot, as close as possible to the rear seats. Limit the loads carried in the vehicle andreduce wind resistance (roof bars, roof rack,bicycle carrier, trailer...). Use a roof box in preference. Remove roof bars and roof racks after use.


At the end of winter, remove snow tyres andrefit your summer tyres.



Observe the recommendations
on maintenance


Check the tyre pressures regularly, whencold, referring to the label in the door aperture, driver's side.
Carry out this check in par ticular:


- before a long journey,

- at each change of season,

- after a long period out of use.
Don't forget the spare wheel and the tyres on any trailer or caravan.


Have your vehicle ser viced regularly (engineoil, oil filter, air filter...) and obser ve theschedule of operations recommended by the manufacturer.




When refuelling, do not continue after the 3 rdcut-off of the nozzle to avoid any overflow.

At the wheel of your new vehicle, it is only after the first 1 800 miles (3 000 kilometres) that you will see the fuel consumption settledown to a consistent average.
Switch off the headlamps and front foglamps when the level of light does not require their use.

Avoid running the engine before moving off,particularly in winter; your vehicle will warmup much faster while driving.

As a passenger, if you avoid connecting your multimedia devices (film, music, videogame...), you will contribute towards limitingthe consumption of electrical energy, and soof fuel. Disconnect your por table devices beforeleaving the vehicle.

Invalid value during manualoperation
This symbol is displayed if a gear
is not engaged correctly (selector
between two positions).

Stopping the vehicle
Before switching off the engine, you canengage position Por N
to place the gearbox in neutral.
In both cases, apply the parking brake toimmobilise the vehicle, unless it is programmedto automatic mode.

If the lever is not in position P, when thePdriver's door is opened or approximately45 seconds after the ignition is switched off, there is an audible signal and amessage appears.)Return the lever to position P
; the audible signal stops and themessage disappears.


Operating fault

When the ignition is on, the lighting of this
warning lamp, accompanied by an audible
signal and a message in the multifunction
screen, indicates a gearbox malfunction.
In this case, the gearbox switches to back-up
mode and is locked in 3rd
gear. You may feel
a substantial knock when changing from Pto R
and from N
to R
. This will not cause any
damage to the gearbox.
Do not exceed 60 mph (10 0 km/h), local speed restrictions permitting.
Have it checked by a CITROËN dealer or aqualified workshop.
This warning lamp may also come on if a door
is opened.
You risk damaging the gearbox:


- if you press the accelerator and brake pedals at the same time,

- if you force the lever from position Pto another position when the batteryis flat.

To reduce fuel consumption when stationary for long periods with the engine running (traffic jam...), positionthe gear lever at Nand apply theparking brake, unless it is programmed in automatic mode.

The rear parking sensors will be deactivated automatically if a genuine CITROËN towbar is used.

Driving advice
Distribution of loads
)Distribute the load in the trailer so that theheaviest 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 per formance. Above
1 000 metres, the maximum towed load must
be reduced b
y 10 % for every 1 000 metres of altitude.
Refer to the "Technical Data" section for details
of the weights and towed loads which apply to your vehicle.
Side wind
)Take into account the increased sensitivity
to side 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.)
To lower the engine speed, reduce your speed.
The maximum towed load on a long inclinedepends on the gradient and the ambient
temperature.
In all cases, keep a check on the coolant
temperature.

Braking

To w i ng a trailer increases the braking distance.
To a v o i d o v e r h e a t i ng of the brakes on a long
mountain type of descent, the use of enginebraking is recommended.


Tyres
)Check the tyre pressures of the towing
vehicle and of the trailer, obser ving the recommended pressures.



Lighting
)Check the electrical lighting and signalling on the trailer.
)If the warning lamp and the
STOP warning lamp come on, stop the vehicle and switch off
t
he engine as soon as possible.
