check engine Citroen DS3 2011 1.G User Guide

Deactivation

In exceptional conditions (starting a vehicle
which is bogged down, stuck in snow, on soft
ground...), it may be advisable to deactivate the
ASR and ESP systems, so that the wheels can
move freely and regain grip.


)
Press the "ESP OFF"
button, located on
the left below the steering wheel.

If this warning lamp comes on in the
instrument panel and the indicator
lamp in the button comes on, this
indicates that the ASR and ESP
systems are deactivated.


Reactivation

These systems are reactivated automatically
each time the ignition is switched back on or
from 30 mph (50 km/h) (except 1.6 litre
THP 150 and R ACING petrol engines).


)
Press the "ESP OFF"
button again to
reactivate them manually.



Operating fault

The ESP/ASR systems offer
exceptional safety in normal driving, but
this should not encourage the driver to
take extra risks or drive at high speed.
The correct functioning of these
systems depends on obser vation of the
manufacturer's recommendations on:


- wheels (tyres and rims),

- braking components,

- electronic components,

- assembly and repair procedures.
After an impact, have these systems
checked by a CITROËN dealer or a
qualified workshop.
If this warning lamp comes on,
accompanied by an audible signal and a
message in the multifunction screen, this
indicates a malfunction of these systems.
Have it checked by a CITROËN dealer or a
qualified workshop.

If you press the accelerator pedal
beyond the point of resistance, the
gearbox selects the gear below to
permit sharper acceleration.
You must press the brake pedal while
star ting the engine.
Never select neutral N
while the vehicle
is moving.
Only engage reverse gear R
when the
vehicle is immobilised, with your foot on
the brake pedal.
In all cases, you must apply the parking
brake to immobilise the vehicle.


"Auto sequential" mode

In the automated mode, you can resume
control temporarily at any time using the
steering mounted control paddles.
The use of these paddles permits manual
selection of the gears in situations which
require a more rapid change-down than in
the automated mode (arrival at a roundabout,
leaving a car park with a steep gradient,
over taking...).
The gearbox engages the required gear if
the engine speed permits. AUTO
remains
displayed in the instrument panel.
After a few minutes, the gearbox resumes
automatic control of the gears.


Stopping the vehicle

Before switching off the engine, you can
change to position N
to be in neutral.
In this case, you must apply the parking brake
to immobilise the vehicle.


Reinitialisation

Reactivation

This system requires a battery with a special
specification and technology (reference
numbers available from a CITROËN dealer or a
qualified workshop).
Fitting a battery not listed by
CITROËN introduces the risk of malfunction of
the system. In the event of a malfunction with the system,
the "ECO OFF"
switch warning lamp flashes,
then comes on continuously.
Have it checked by a CITROËN dealer or a
qualified workshop.
In the event of a fault in STOP mode, the
vehicle may stall. It is then necessary to switch
off the ignition and star t the engine again using
the key.

Checking levels

Check all of these levels regularly and top them up if necessary, unless other wise indicated.
If a level drops significantly, have the corresponding system checked by a CITROËN dealer or a qualified workshop.


Oil level


Engine oil change

Refer to the Maintenance and Warranty Guide
for details of the inter val for this operation.
In order to maintain the reliability of the engine
and emission control system, the use of
additives in the engine oil is prohibited.


Oil grade

The oil must be suitable for your engine
and conform to the manufacturer's
recommendations.



Brake fluid level


Changing the fl uid

Refer to the Maintenance and Warranty Guide
for details of the inter val for this operation.


Fluid specifi cation

The brake fluid must conform to the
manufacturer's recommendations and meet the
DOT4 standard.
The brake fluid level should be close
to the "MA X" mark. If it is not, check
the brake pad wear. The reading will only be correct if the
vehicle is on level ground and the
engine has been off for more than
30 minutes.
The check is carried out either when the ignition
is switched on using the oil level indicator in the
instrument panel, or using the dipstick.
It is normal to top up the engine
oil between ser vices. CITROËN
recommends that you check the oil
level and top up if necessary, every
3 000 miles (5 000 kilometres).

Changing the coolant

The coolant does not have to be changed.


Fluid specifi cation

The coolant must conform to the
manufacturer's recommendations.



Screenwash fluid level


Fluid specifi cation

For optimum cleaning and to avoid freezing,
this fluid must not be topped up or replaced
with water.



Take care when carrying out checks
under the bonnet as some parts of the
engine can be very hot (risk of burns).



Coolant level

Top up the level when necessary.
The coolant level should be close
to the "MA X" mark but should never
exceed it.
When the engine is warm, the
temperature of the coolant is regulated by the
fan. This can operate with the ignition off.

On vehicles which are fitted with a par ticle
emission filter, the fan may operate after
the vehicle has been switched off, even if
the engine is cold.

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 any risk of scalding, unscrew the cap
by two turns to allow the pressure to drop.
When the pressure has dropped, remove the
cap and top up the level.

Diesel additive level
(Diesel engine with particle
emission filter)

Topping up

This additive must be topped up by a CITROËN
dealer or a qualified workshop without delay.











Used products

Avoid prolonged contact of used oil or
fluids with the skin.
Most of these fluids are harmful to
health or indeed very corrosive.
Do not discard used oil or fluids into
sewers or onto the ground.
Take used oil to a CITROËN dealer or
a qualified workshop (France) or to an
authorised waste disposal site. A additive reser voir low level is
indicated by fixed illumination of
this warning lamp, accompanied by an audible
warning and a message in the multifunction
screen.
