2021 CITROEN C4 AIRCROSS oil change

11
Limit the causes of excess consumption
Spread loads throughout the vehicle; place the heaviest items in the
bottom of the boot, as close as possible to the rear seats.
Limit the loads carried in the vehicle and reduce wind resistance (roof
bars, roof rack, bicycle carrier, trailer...). Use a roof box in preference.
Remove roof bars and roof racks after use.
At the end of winter, remove snow tyres and refit your summer tyres.
Observe the recommendations on
maintenance
Check the tyre pressures regularly, when cold, referring to the label in
the door aperture, driver's side.
Carry out this check in particular:
-
b
efore a long journey,
-

a
t each change of season,
-

a
fter a long period out of use.
Don't forget the spare wheel and the tyres on any trailer or caravan.
Have your vehicle serviced regularly (engine oil, oil filter, air filter...) and
observe the schedule of operations recommended by the manufacturer.
When refuelling, do not continue after the third cut-off of the nozzle to
avoid any over flow.
At the wheel of your new vehicle, it is only after the first 1 800 miles
(3
000 kilometres) that you will see the fuel consumption settle down to
a consistent average.

Checking levels
Take care when working under the bonnet, as certain areas of the engine may be extremely hot (risk of burns) and the cooling fan could start at
any time (even with the ignition off).
Oil level
The check of the the level is done
out with the dipstick, located under
the bonnet. Refer to the description
of your engine compartment for the
position of the dipstick.Engine oil change
Refer to the maintenance and warranty guide
for details of the interval for this operation.
In order to maintain the reliability of the engine
and emission control system, never use
additives in the engine oil.
Oil specification
The oil must be the correct grade for your
engine and conform to the manufacturer's
recommendations.
Check all of these levels regularly, in line with the maintenance and warranty guide. Top them up if necessary, unless other wise indicated.
If a level drops significantly, have the corresponding system checked by a CITROËN dealer or a qualified workshop.
Dipstick
There are two marks on the dipstick:
A = maximum
If the level is above this
mark, contact a CITROËN
dealer or a qualified
workshop.
B = minimum
Top up the level through the
oil filler orifice, using the
correct grade of oil for your
engine. The level must never
be below this mark.
This check will only be correct if the vehicle is
on level ground and the engine has been off for
more than 30 minutes.
It is normal to top up the oil level between
two services (or oil changes). CITROËN
recommends that you check the level, and top
up if necessary, every 3 000 miles (5 000 km).
After topping up the oil, the check when
switching on the ignition with the oil level
indicator in the instrument panel is not valid
during the 30 minutes after topping up.
