Warning and indicator
lamps
Displayed as symbols, the warning and indicator
lamps inform the driver of the occurrence of a
malfunction (warning lamps) or of the operating
status of a system (operation or deactivation
indicator lamps). Certain lamps light up in two
ways (fixed or flashing) and/or in several colours.
Associated warnings
The illumination of a lamp may be accompanied
by an audible signal and/or a message displayed
in a screen.
Relating the type of alert to the operating status
of the vehicle allows you to determine whether
the situation is normal or whether a fault has
occurred: refer to the description of each lamp
for further information.
When the ignition is switched on
Certain red or orange warning lamps come on
for a few seconds when the ignition is switched
on. These warning lamps should go off as soon
as the engine is started.

AdBlue® range indicators
(BlueHDi)
The Diesel BlueHDi engines are equipped with
a system that associates the SCR (Selective
Catalytic Reduction) emissions control system
and the Diesel particle filter (DPF) for the
treatment of exhaust gases. They cannot
function without AdBlue
® fluid.
When the level of AdBlue® falls below the
reserve level (between 1,500 and 0 miles (2,400
and 0 km)), a warning lamp lights up when the ignition is switched on and an estimate
of the distance that can be travelled before
engine starting is prevented is displayed in the
instrument panel.
The engine starting prevention system required by regulations is activated
automatically once the AdBlue
® tank is empty.
It is then no longer possible to start the

The distance which can still be travelled with the fuel remaining in the tank (related
to the average fuel consumption over the last
few miles (kilometres) travelled).
This value may fluctuate if a change of driving style or terrain results in a
significant change in the current fuel
consumption.
Dashes are displayed when the range falls below
20 miles (30 km).
After filling with at least 5 litres of fuel, the range
is recalculated and is displayed if it exceeds 60
miles (100 km).

Advice
Remote control
The remote control is a sensitive, high-
frequency device; avoid handling it in your
pocket, due to the risk of unintentionally
unlocking the vehicle.
Avoid pressing the remote control buttons
while out of range of the vehicle, due to
the risk of rendering the remote control
inoperative. It would then be necessary to
reset it.
The remote control does not work when the key is in the ignition switch, even when the
ignition is switched off.
Anti-theft protection
Do not modify the electronic vehicle
immobiliser, as this might result in
malfunctions.
For vehicles with a key ignition switch,
remember to remove the key and turn the
steering wheel to engage the steering lock.
Locking the vehicle
Driving with the doors locked could make
it more difficult for the emergency services to
enter the vehicle in an emergency.
As a safety precaution, remove the key from
the ignition or take the electronic key with you
when leaving the vehicle, even for a short
time.
Purchasing a second-hand vehicle
Have the key codes memorised by a
CITROËN dealer, to ensure that the keys in
your possession are the only ones able to
start the vehicle.
In order to preserve the battery in the
electronic key and the vehicle's battery:
– All of the "hands-free" functions go into extended standby after 21 days of non-use.
To restore these functions, unlock the vehicle
using the remote control and start the engine.
Electrical interference
The electronic key may not operate if
close to certain electronic devices: telephone
(switched on or on standby), laptop computer,
strong magnetic fields, etc.
Do not throw remote control batteries away, as they contain metals that are
harmful to the environment. Take them to an
approved disposal point.
Emergency procedures

Safety
► Or, depending on version, turn the “Grip control” knob to this position.Deactivation is confirmed by the illumination of this indicator lamp in the
instrument panel and the display of a message.
The ASR system is reactivated automatically
every time the ignition is switched back on or
from 31 mph (50 km/h).Reactivation is manual below 31 mph (50 km/h).
Malfunction
In the event of a system malfunction, this warning lamp comes on, accompanied by
an onscreen message and audible signal.
Contact a CITROËN dealer or a qualified
workshop to have the systems checked.
ASR / DSC
These systems enhance safety during
normal driving, but should not encourage
the driver to take extra risks or drive at high
speed.
It is in conditions of reduced grip (rain, snow,
ice) that the risk of loss of grip increases. It
is therefore important for your safety to keep
these systems activated in all conditions, and
particularly in difficult conditions.
Correct operation of these systems depends
on compliance with the manufacturer's
recommendations relating to the wheels
(tyres and rims), braking and electronic
components, as well as the assembly and
repair procedures used by CITROËN dealers.
The use of snow tyres is recommended, to
ensure that these systems remain effective
in winter conditions. All four wheels must be
fitted with tyres approved for the vehicle.
Grip control
A special, patented traction control system which improves driveability on snow, mud and sand.
This system, optimised for operation in a range
of conditions, enables you to manoeuvre in most
slippery conditions (encountered during normal
passenger car use).
When combined with all-season Peak Mountain
Snow Flake tyres, this system offers a
compromise between safety, grip and driveability.
The accelerator pedal should be pressed
sufficiently to allow the system to harness the
power of the engine. Operation at high engine
speeds is completely normal.
A five-position selector knob allows you to
choose the setting best suited to the driving
conditions encountered.
An indicator lamp associated with each mode
comes on, accompanied by the display of a
message to confirm your choice.
Operating modes


Standard (ESC)
This mode is calibrated for a low level of wheel spin, based on the different levels
of grip normally encountered on the road.
Whenever the ignition is switched off, the
system automatically resets to this mode.
Snow
This mode adapts its strategy to the conditions of grip encountered for each of
the two front wheels on moving off.
(mode active up to 50 mph (80 km/h))
All terrain (mud, damp
grass, etc.)
This mode, when moving off, allows considerable spin on the wheel with the
least grip to optimise clearing of the mud and to
regain grip. At the same time, the wheel with the
most grip is controlled in such a way as to
transmit as much torque as possible.
When moving, the system optimises wheel spin
to respond to the driver's requirements as fully
as possible.
(mode active up to 31 mph (50 km/h))
Sand
This mode allows little spin on the two driving wheels at the same time to allow
the vehicle to move forward and limit the risks of
getting stuck in the sand.
(mode active up to 75 mph (120 km/h))
Do not use the other modes on sand as
the vehicle may become stuck.
You can deactivate the ASR and DSC systems by turning the knob to the "OFF "
position.
The ASR and DSC systems will no longer act on the operation of the engine
