MAINTENANCE AND ANTIPOLLUTION ADVICE
Your vehicle complies with criteria for
recycling and recovering vehicles at the
end of their service life, which entered
into force in 2015.
Some parts of your vehicle have there-
fore been designed to facilitate future
recycling.
These parts are easy to remove so
that they can be recovered and reproc-
essed by recycling companies.
By virtue of its design, moderate fuel
consumption and initial settings, your
vehicle also conforms to current anti-
pollution regulations. The manufac-
turer is actively striving to reduce pol-
lutant exhaust gas emissions and to
save energy. But the fuel consumption
of your vehicle and the level of pollutant
exhaust gas emissions are also your
responsibility. Ensure that it is main-
tained and used correctly.Maintenance
It is important to remember that failure to
respect antipollution regulations could
lead to legal action being taken against
the vehicle owner. In addition, replacing
engine, fuel supply system and exhaust
components with parts other than those
originally recommended by the manu-
facturer may alter your vehicle so that
it no longer complies with antipollution
regulations.
Have your vehicle adjusted and
checked by an approved Dealer, in ac-
cordance with the instructions given in
your maintenance schedule: they will
have all the equipment necessary for
ensuring that your vehicle is maintained
to its original standard.
Engine adjustments
– Air filter, diesel filter: a choked el-
ement will reduce efficiency. It must
be replaced.
– Idle speed: this does not require ad- justment.
Exhaust gas monitoring
system
The exhaust gas monitoring system will
detect any operating faults in the vehi-
cle’s antipollution system.
If this system malfunctions, toxic sub-
stances may be released into the at-
mosphere or damage may occur.
ÄThis warning light on the in-
strument panel will indicate if
there are any faults in the system:
This lights up when the ignition is
switched on and goes out when the
engine is started.
– If it lights up continuously, consult an approved Dealer as soon as possi-
ble;
– if it flashes, reduce the engine speed until the light stops flashing. Contact
your approved dealer as soon as
possible.
Refer to the information on
«Additive tank» in Section 1.

Operating faults
When the system detects an operating
fault the message “CHECK ESC” and
warning light
© and  appear
on the instrument panel. In this case,
the ESC and traction control system
are deactivated.
Consult an approved dealer.
Electronic stability program
(ESC) with understeer control
and traction control
Electronic stability control ESC
This system helps you to keep control
of the vehicle in critical driving condi-
tions (avoiding an obstacle, loss of grip
on a bend, etc.).
Operating principle
A sensor in the steering wheel detects
the direction selected by the driver.
Other sensors throughout the vehicle
measure the actual direction.
The system compares driver input to
the actual trajectory of the vehicle and
corrects the trajectory if necessary by
controlling the braking of certain wheels
and/or engine power. In the event that
the system is engaged, indicator light
 flashes on the instrument panel.
DRIVING CORRECTION DEVICES AND AIDS (2/8)
Understeer control
This system optimises the action of the
ESC in the case of pronounced under-
steer (loss of front axle road holding).
Traction control
This system helps to limit wheelspin of
the drive wheels and to control the ve-
hicle when pulling away accelerating or
decelerating.
Operating principle
Using the wheel sensors, the system
measures and compares the speed of
the drive wheels at all times and slows
down their over-rotation. If a wheel is
starting to slip, the system brakes au-
tomatically until the drive supplied be-
comes compatible with the level of grip
under the wheel again.
The system also adjusts the engine
speed to the grip available under the
wheels, independently of the pressure
exerted on the accelerator pedal.
These functions are an ad-
ditional aid in the event of
critical driving conditions,
enabling the vehicle behav-
iour to be adapted to suit the driving
conditions.
The functions do not take the place
of the driver. They do not increase
the vehicle’s limits and should
not encourage you to drive more
quickly. Therefore, they can under
no circumstances replace the vigi-
lance or responsibility of the driver
when manoeuvring the vehicle (the
driver must always be ready for
sudden incidents which may occur
when driving).

2.18
DRIVING CORRECTION DEVICES AND AIDS (3/8)
Emergency brake assist
This system supplements the ABS
and helps reduce vehicle stopping dis-
tances.
Operating principle
The system is for detecting an emer-
gency braking situation. In this case,
the braking assistance immediately de-
velops maximum power and may trig-
ger ABS regulation.
ABS braking is maintained as long as
the brake pedal is applied.
Hazard warning lights switching on
Depending on the vehicle, these may
light up in the event of sudden decel-
eration.
Operating faults
When the system detects an operat-
ing fault the message “CHECK ABS”
appears on the instrument panel along
with the
© warning light.
Consult an approved dealer.
Driver assistance with a
trailer
This system helps to maintain control
over the vehicle while using a trailer.
It detects shaking caused by towing a
trailer under certain driving conditions.
Operating conditions
– The towbar must be approved by an authorised dealer;
– the harness must be approved by an authorised dealer;
– the towbar must be connected to the vehicle.
Operating principle
The function stabilises the vehicle by:
– asymmetric braking of the front wheels to reduce shaking caused by
the trailer;
– braking of all four wheels and limita- tion on engine torque to reduce the
vehicle speed until the shaking has
stopped.
Warning light
 flashes on the in-
strument panel to inform the driver.
Active emergency braking
Using the sensor 1, the system calcu-
lates the distance separating the vehi-
cle from the one in front and alerts the
driver if there is a risk of a front-end col-
lision. The driver can then brake the ve-
hicle to limit the damage arising from a
collision.
Note: Make sure that the sensor 1 is
not obscured (by dirt, mud, snow, etc.).

DRIVER CORRECTION DEVICES AND AIDS (5/8)
Active emergency braking
This function is an additional driving aid. This function is not under any
circumstances intended to replace the due care and attention of the
driver, who should at all times be in control of the vehicle.
System servicing/repairs
– In the event of an impact, the sensor alignment may become changed, and \
its operation will consequently be affected. Deactivate the function, then consult
an authorised dealer.
– Any work in the area where the radar is located (repairs, replacements,\
touch- ing up of paintwork) must be carried out by a qualified professional.
Only an authorised dealer is qualified to service the system.
In the event of system disturbance
Some conditions can disturb or damage the operation of the system, such \
as:
– a complex environment (metal bridge, tunnel etc.) ;
– poor weather conditions (snow, hail, black ice, etc.).
Risk of inadvertent braking.
Operating faults
The warning lights
 and 
lit up on the instrument panel accom-
panied by the message “WARNING
AEBSCHECK” indicate a system
fault. Consult an approved dealer.
When the system detects that the func-
tion is not available, the
 warn-
ing light lights up on the instrument
panel and stays on, with the message
“WARNING AEBS DISABLED”.
There are two possibilities:
– The system is temporarily disrupted (for example: radar obscured by
dirt, mud, snow etc.). In this case,
park the vehicle and switch off the
engine. Clean the detection zone of
the radar. When you next start the
engine, the warning light and the
message go out;
– If this is not the case, this may arise from another cause; contact an
Approved Dealer.

SEQUENTIAL GEARBOX (4/5)
Operation in automatic mode
Automatic mode is selected by default
every time the ignition is switched on.
The letter A appears on the display.
The vehicle is controlled using the ac-
celerator and the brake. Gears will
change automatically at the correct
moment and at a suitable engine speed
because the automatic mode takes the
road surface and the chosen driving
style into consideration.
Gears may be shifted manually in this
mode. Pushing the lever forwards
or backwards shifts a gear upwards
(except if there is a risk of underrev-
ving) or downwards (except if there is a
risk of overrevving).
Note: automatic mode takes account
of:
– the position and speed of depression of the accelerator pedal to assess
driving style and select the optimum
gear;
– action on the brake pedal, to com- mence engine braking in preparation
for a downshift.
You can stop the vehicle at red lights,
with the gear engaged, by depressing
the brake pedal; there is no need to
change to neutral (N).
The vehicle will move off again:
– either slowly, if you release the brake without accelerating (e.g. when in a
traffic jam);
– or quickly, if you release the brake and accelerate.
Accelerating and overtaking
– Slowly depress the accelerator pedal to accelerate gradually;
The oil level in the automatic gear-
box system reservoir varies depend-
ing on use. Adding oil is strictly
forbidden (except by qualified ap-
proved network personnel).
– to obtain maximum vehicle per-
formance regardless of the mode
selected (automatic or manual),
quickly depress the accelerator
pedal beyond the kickdown point.
The speed with which you depress the
pedal will allow you to downshift ac-
cording to the vehicle’s capabilities.
Parking the vehicle
It is possible to park in gear (for exam-
ple, on a slope):
– with the ignition on, select a gear with your foot on the brake ;
– check that a gear other than N is dis- played on the instrument panel, then
remove the ignition key;
– apply the handbrake.
To disengage the gear, switch on the
ignition without starting the engine and
shift the selector lever to neutral with
the brake pedal depressed . Check
that N is displayed on the instrument
panel.

2.49
SEQUENTIAL GEARBOX (5/5)
Load position
When the vehicle is driven loaded,
press the 6 switch on the dashboard.
The indicator light
§ on the instru-
ment panel will light up.
Load mode is deselected every time
the engine is switched off. It will be nec-
essary to select it again.
Load mode may be used to equal effect
in both automatic and manual modes.
6
Bleep– If you hold the vehicle on a slope for too long without applying the
brakes or handbrake, you will strain
the system (risk of overheating the
clutch).
In this case, an intermittent beep- ing sound will remind you that you
should put your foot on the brake
pedal or apply the handbrake.
– Never leave the vehicle with the engine running when in gear. For
safety reasons you will hear an in-
termittent beeping sound when you
open the door if you have not shifted
into neutral or you have not switched
off the ignition or depressed the
brake pedal.
Special circumstances
On a slippery surface or surface with
little grip, change to manual mode
(A/M) and select second gear before
accelerating to avoid wheelspin.
Operating faults
i
If this warning light comes on
when the vehicle is in motion , it
indicates a fault in the system. In most
cases, you may still drive the vehicle,
although it will not function perfectly.
Contact an approved dealer as soon as
possible.
Towing a vehicle with a sequential
gearbox
If the gearbox is stuck in a gear:
– switch on the ignition;
– select neutral with the brake pedal
depressed;
– check that the gearbox is in neutral (by pushing the vehicle, for exam-
ple).
If you cannot find neutral you must tow
the vehicle with the front wheels raised.
The vehicle should always be towed
with the ignition switched off.

Please note when work-
ing close to the engine that
it may be hot. In addition,
the engine cooling fan may
start at any moment. The

warning light in the engine compart-
ment reminds you of this.
Risk of injury.Before performing any
action in the engine com-
partment, the ignition must
be switched off (please see
the information on “Starting, stop-
ping the engine” in Section 2).

4.4
ENGINE OIL LEVEL: general information (1/2)
If the level is at the minimum
The “TOP-UP OIL LEVEL” message
and warning light
© are displayed
on the instrument panel.
It is vital to top up the oil as soon as
possible.
The display only warns the
driver if the oil level is at the
minimum level. It does not
inform the driver that the oil
level has exceeded the maximum
level as this can only be measured
using a dipstick.
It is normal for an engine to use oil for
lubrication and cooling of moving parts
and it is normal to top up the level be-
tween oil changes.
However, contact an approved Dealer if
more than 0.5 litres is being consumed
every 600 miles (1,000 km) after the
running in period.
Oil change frequency: check the oil
level from time to time and certainly
before any long journey to avoid the
risk of damaging your engine.
Reading the oil level
The oil level should be read with the ve-
hicle on level ground, after the engine
has been switched off for some time.
The dipstick must be used to read
the exact oil level and make sure
that the maximum level has not been
exceeded (risk of engine damage).
Refer to the following pages.
The instrument panel display only
alerts the driver when the oil level is at
its minimum.
