SCR system
Using a liquid called AdBlue
®
that contains urea,
a catalytic converter turns up to 85% of nitrogen
oxides (NOx) into nitrogen and water, which are
harmless to health and the environment.
The AdBlue
®
is contained in a special tank
holding about 17 litres.
Its capacity allows a driving range of
approximately 5,600miles (9,000km), highly
dependent on your driving style.
An alert system is triggered automatically once
the reserve level is reached: you can then drive for
a further 1,500miles (2,400km) before the tank is
empty and the vehicle disabled.
For more information on the Warning and
indicator lamps and the associated alerts,
or the Indicators, refer to the corresponding
sections.
Once the AdBlue
®
tank is empty, a system
required by regulations prevents starting
of the engine.
If the SCR system is faulty, the level of
emissions from the vehicle will no longer meet
the Euro 6 standard: the vehicle becomes
polluting.
In the event of a confirmed fault with the SCR
system, you must go to a dealer or a qualified
workshop as soon as possible: after travelling
a distance of 685miles (1,100km), a system
will be triggered automatically to prevent
engine starting.
Brake pads
Brake wear depends on the style of driving,
particularly in the case of vehicles used in
town, over short distances. It may be necessary to
have the condition of the brakes checked, even
between vehicle services.
Unless there is a leak in the circuit, a drop in the
brake fluid level indicates that the brake pads are
worn.
After washing the vehicle, moisture, or in
wintry conditions, ice can form on the
brake discs and pads: braking efficiency may
be reduced. Gently dab the brakes to dry and
defrost them.
Brake disc wear
For information on checking brake disc
wear, contact a dealer or a qualified
workshop.
Electric parking brake
This system does not require any routine
servicing. However, in case of an issue, do
not hesitate to have the system checked by a
dealer or a qualified workshop.
For more information on the Electric
parking brake, refer to the corresponding
section.
Wheels and tyres
The inflation pressure of all tyres,
including the spare wheel, must be
checked on "cold” tyres.
The pressures indicated on the tyre pressure label
are valid for "cold" tyres. If you have driven for
more than 10 minutes or more than 6 miles (10
kilometres) at over 31 mph (50km/h), add 0.3 bar
(30 kPa) to the values indicated on the label.
Under-inflation increases fuel
consumption. Non-compliant tyre
pressure causes premature wear on tyres and
has an adverse effect on the vehicle's road
holding - risk of an accident!
Driving with worn or damaged tyres reduces the
braking and road holding performance of the
vehicle. It is recommended to regularly check the
condition of the tyres (tread and sidewalls) and
wheel rims as well as the presence of the valves.
When the wear indicators no longer appear set
back from the tread, the depth of the grooves is
less than 1.6 mm; it is imperative to replace the
tyres.
Using different size wheels and tyres from those
specified can affect the lifetime of tyres, wheel
rotation, ground clearance, the speedometer
reading and have an adverse effect on road
holding.
Fitting different tyres on the front and rear axles
can cause the ESC to mistime.
Shock absorbers
It is not easy for drivers to detect when
shock absorbers are worn. Nevertheless,
the shock absorbers have a major impact on
road-holding and braking performance.
For your safety and driving comfort, it is important
to have them regularly checked by a dealer or a
qualified workshop.
Timingand accessory kits
Timingand accessory kits are used from
the time the engine is started until it is
switched off. It is normal for them to wear over
time.
A faulty timing or accessory kit can damage
the engine, rendering it unusable. Observe the
recommended replacement frequency, stated in
distance travelled or time elapsed, whichever is
reached first.
AdBlue
®
(BlueHDi)
To respect the environment and ensure
compliance with the Euro 6 standard, without
adversely affecting the performance or fuel
consumption of Diesel engines, the Manufacturer
has taken the decision to equip its vehicles with a
system that associates SCR (Selective Catalytic
Reduction) with a Diesel particle filter (DPF) for
the treatment of exhaust gases.
