Checking Levels - CITROËN C4 Owner's Handbook Manual

CHECKING LEVELS

Check all of these levels regularly, in
line with the maintenance and warranty
guide. Top them up if necessary, unless
otherwise indicated.
If a level drops signifi cantly, have the
corresponding system checked by a
CITROËN dealer or a qualifi ed work-
shop.
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 is carried out either
when the ignition is switched
on using the oil level indicator
in the instrument panel, or us-
ing the dipstick.
It 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 be-
tween two services (or oil changes).
CITROËN recommends that you check
the level, and top up if necessary, every
3 000 miles (5 000 kms).
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.

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,
the use of additives in the engine oil is
prohibited.
Oil specifi cation
The oil must be the correct grade for
your engine and conform to the manu-
facturer's recommendations.
Brake fluid level
The brake fl uid level should be
close to the "MAX" mark. If it is
not, check the brake pad wear.
Changing the fl uid
Refer to the maintenance and warranty
guide for details of the interval for this
operation.
Fluid specifi cation
The brake fl uid must conform to the
manufacturer's recommendations.
Power steering fluid level
The power steering fl uid level
should be close to the "MAX"
mark. With the engine cold, un-
screw the cap to check the level.
Coolant level
The coolant level should be
close to the "MAX" mark but
should never exceed it.
When the engine is warm, the
temperature of the coolant is regulated
by the fan.
In addition, as the cooling system is
pressurised, wait at least one hour after
switching off the engine before carrying
out any work.
To avoid any risk of scalding, unscrew
the cap by two turns to allow the pres-
sure to drop. When the pressure has
dropped, remove the cap and top up
the level.
Fluid specifi cation
The coolant must conform to the manu-
facturer's recommendations.
The cooling fan may start after
switching off the engine: take
care with articles and clothing
that might become caught by the
fan blades.
