2013 Citroen C8 brakes

Gearbox and stearing wheel
40

Good practice

Never select position N
when the
vehicle is moving.
Never select positions P
or R
unless
the vehicle is stationary.
Never change between positions to
optimise braking on a slippery surface.
There is a risk of damage to the
gearbox:


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

- if you force the lever from position P
to another position in the event of a
battery failure.
When the engine is at idle, brakes
not applied, if position R
, D
or M
is
selected the vehicle moves even
without the accelerator being pressed.
For this reason, do not leave children
unsupervised inside the vehicle,
with the engine running
.


Operating abnormality

Any operating abnormality is indicated
by an audible signal, accompanied by
the message "Automatic gear fault"

on the display and fl ashing of the Snow
snowfl ake on the instrument panel.
In this situation the gearbox operates
in downgrade mode (locked in 3rd
gear). You may feel a substantial knock
when changing from P
to R
and from N

to R
(this will not cause any damage to
the gearbox).
Do not exceed 60 mph (100 km/h),
keeping within the limit of local speed
restrictions.
Contact a CITROËN dealer as soon as
possible.
You can return to the automatic
programme at any time.


- Press button
7 again to switch off
the programme you are in.



Snow programme

In addition to the automatic
programme, there is a special
Snow programme.
This improves starting
and drive when traction is
poor. The snowfl ake appears on the
instrument panel display.


- Press button
7 once the
vehicle has been started
and position D
selected.
The gearbox adapts to driving
on slippery roads.

SAFETY

Driving safely
TRACTION CONTROL (ASR)
AND DYNAMIC STABILITY
CONTROL
(ESP)

Activation of the ASR and ESP
systems
When the ignition is on, the ASR and
ESP systems are always active.


Disarming the ASR/ESP
systems
In certain conditions (vehicle stuck in
mud or snow, or on loose ground...), it
could prove useful to disarm the ASR
and ESP systems to make the wheels
spin and regain grip.
-
Press the switch, situated under
the steering wheel on the left of the
fascia.
The indicator light comes on
accompanied by a message:
the ESP and ASR systems
no longer act on the engine
operation, but continue to act
on the brakes.
Operating check
The ASR/ESP systems offer
increased safety during normal
driving, but should not incite the
driver to take risks or to drive at high
speed.


The operation of these systems is
ensured if the recommendations
of the manufacturer regarding
the wheels (tyres and rims), the
braking components, the electronic
components and the fi tting and repair
procedures within the CITROËN
network are observed.


After an impact, have these systems
checked by a CITROËN dealer .

They engage again:
-
automatically above 30 mph
(50 km/h),
- manually by pressing the switch
again.


Operation of the ASR and
ESP systems
The warning light fl ashes if
the ASR or ESP is activated.

These systems are linked and
complement the ABS.
The ASR system optimises drive to
prevent the wheels skidding, by acting
on the brakes of the drive wheels
and on the engine. It also allows the
directional stability of the vehicle to be
improved on acceleration.
If there is a variation between the
trajectory followed by the vehicle and
that required by the driver, the ESP
system automatically acts on the
engine and the brake of one or more
wheels, in order to put the vehicle back
on course, within the limits of the laws
of physics. When a malfunction of the
systems occurs, the indicator
light comes on, accompanied
by an audible signal and a
message on the display.

Consult a CITROËN dealer to have the
system checked.

Driving safely


TYRE UNDER-INFLATION
DETECTION

Sensors check the tyre pressure during
driving, and trigger a warning in the
event of a malfunction (speed greater
than approx.15 mph [25 km/h]) or
puncture.
An outline representing one or more
wheels fl ashing indicates the location
of the wheel or wheels concerned.

Flat tyre

The SERVICE warning light
comes on, accompanied
by the message "Tyre(s)
defl ated"
, an outline on the display,
and an audible signal.
Check the tyre pressure as soon as
possible. If the damaged tyre is temporarily
stored in the boot, it will again emit
this message to remind you of the
necessity of having it repaired. This will
prevent another warning of the same
type being displayed.


Sensor(s) not detected

The SERVICE warning light
comes on, accompanied
by the message "X tyre
pressure sensor(s) missing"
, an
outline on the display and an audible
signal.
Under-infl ation detection is absent
from one (or several) tyre(s). Consult a
CITROËN dealer to replace the faulty
sensor(s). This message is also displayed
when one of the tyres is away
from the vehicle (being repaired)
or when a wheel without a sensor is
fi tted.
All repairs and changing of
tyres on a wheel fi tted with this
system must be carried out by a
CITROËN dealer.

The tyre under-infl ation detection
system is a driving aid which does
not take the place of

the

vigilance or
the responsibility of the driver.

This system does not remove the
need to have the tyre pressure
checked regularly (including the spare
wheel), to ensure that the dynamic
performance of the vehicle remains at
its best and to avoid premature wear
of the tyres, in particular in the case
of arduous driving (heavy load, high
speed).
The system may temporarily be
disturbed by radio broadcasts on a
frequency close to it.


Puncture

The STOP warning light
comes on, accompanied
by the message
"Punctured tyre(s)"
, an outline on the
display and an audible signal.
Stop immediately, avoiding any sudden
movement of the steering wheel and
the brakes.
Change the damaged (punctured or
very defl ated) tyre, and have the tyre
pressure checked as soon as possible.
Refer to the "Changing a wheel"
section of chapter 7.

Towing a trailer

On the contrary, use a high gear to
lower the engine speed and reduce
your speed.
In all cases, pay attention to the
coolant temperature.
Brakes:
towing increases the braking
distance. Drive at a moderate speed,
change down early and brake
gradually.


Automatic adjustment
For vehicles with Xenon bulbs, and if
the change in load makes it necessary,
this system automatically corrects the
height of the beam after approximately
2 minutes. The driver is then assured
of having optimum lighting and not
causing a nuisance to other road
users.


In certain cases of particularly
arduous use (towing the
maximum load up a steep slope
in high temperatures), the engine
automatically limits its power. In this
case, cutting off the air conditioning
allows the engine power to be
recovered, and therefore the towing
speed to be signifi cantly increased
(approximately 12 mph [20 km/h]
more). Sequential control of the
gearbox may also become unavailable.

Lighting

Bicycle carrier

Refer to the "Identifi cation
features" section of chapter 8. Refer to the "Steering wheel
controls" section of chapter 3.
When using a trailer connection,
you must add a fuse. Refer to
the "Changing a fuse" section of
chapter 7.




If the coolant temperature warning light
comes on, stop the vehicle and switch
off the engine as soon as possible.

Tyres:
check the tyre pressures of
the towing vehicle and of the trailer,
observing the recommended pressure.
Side wind:
sensitivity to side wind is
increased. Drive smoothly and at a
moderate speed.






Towbar

We recommend the use of original
CITROËN towbars, which have been
tested for endurance from the design
stage of your vehicle.
Towing equipment must be fi tted in
accordance with the manufacturer's
instructions, with particular attention to
the towing capacities of your vehicle,
the load towed, the nose weight and
the electrical connection. As this fi tting
should be carried out by a professional,
we recommend that you entrust the
fi tting of this equipment to a CITROËN
dealer.
In accordance with the general
instructions referred to above, we draw
your attention to the risk connected
with fi tting a towbar or other electrical
accessory which is not recommended
by the CITROËN network. Fitting such
equipment could result in a failure
of your vehicle's electronic system.
Please contact a CITROËN dealer fi rst
for further information.
Manual adjustment
Adjust your headlamps so as not to
dazzle other road users. Check the
electrical signalling of the trailer.
If you fi t a bicycle carrier on
the tailgate, deactivate the
rear wiper from the display's
confi guration menu.
