level measurement invalid" in the instrument panel.
Contact a CITROËN dealer or a qualified
workshop.
In the event of a fault with the electric
i ndicator, the engine oil level is no longer
monitored.
If the system is faulty, you must check the
engine oil level using the manual dipstick
located under the bonnet.
For more information on Checking levels ,
refer to the corresponding section.
AdBlue® range indicators
These range indicators are present only on
BlueHDi Diesel versions.
Once the AdBlue
® tank is on reser ve or after
detection of a

fault with the SCR emissions
control system, when the ignition is switched
on, an indicator displays an estimate of the
distance that can be covered, the range, before
engine starting is prevented.
In the event of the risk of non-
starting related to a lack of
AdBlue
®
The engine starting prevention system
required by regulations is activated
automatically once the AdBlue
® tank is
e m pt y.

indicating the remaining range in miles or
kilometres.
When driving, this message is displayed every

Manual gearbox
The gearbox does not require any
maintenance (no oil change).
Automatic gearbox
The gearbox does not require any
maintenance (no oil change).
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.
Brake disc wear
For information on checking brake
disc wear, contact a CITROËN
dealer or a
qualified workshop.
Electric parking brake
This system does not require any
specific check. However, in the
event of a problem, have the system
checked by a
CITROËN dealer or
a


qualified workshop.
For more information on the Electric
parking brake , refer to the corresponding
section.
Wheels and tyres
The pressure must be checked on
all tyres, including the spare wheel,
when the tyres are "cold", at least
once a
month and before a long
j o u r n ey. The pressures given 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 more than 31 mph (50 km/h),
0.3 bar (30 kPa) should be added to the values
given 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
braking efficiency and control of the vehicle's
steering. Regular inspections of the condition
of tyres (tread and sides) and rims are
recommended as well as making sure that
valves are fitted.
Using different size wheels and tyres from
those specified can affect the lifetime of tyres,
wheel rotation, ground clearance and 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.
