Practical information -> Checking levels for Your Citroen C4 SUV Second Generation (2010-2018)

Practical information  
Checking levels  
Check all of these levels regularly, in line with the manufacturer's service schedule. Top them up if necessary, unless otherwise indicated.  
If a level drops significantly, have the corresponding system checked by a CITROËN dealer or a qualified workshop.  
Checking using  
the dipstick  
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).  
If you find that the level is above the A mark or  
below the B mark, do not start the engine.  
F
Locate the dipstick in the engine  
compartment of your vehicle.  
-
If the level is above the MAX mark (risk  
of damage to the engine), contact a  
CITROËN dealer or a qualified workshop.  
If the level is below the MIN mark, you  
must top up the engine oil.  
For more information on the petrol or Diesel  
engine, refer to the corresponding section.

Take the dipstick by its coloured grip and  
remove it completely.  
Wipe the end of the dipstick using a clean  
non-fluffy cloth.  
Refit the dipstick and push fully down, then  
pull it out again to make the visual check:  
the correct level is between the marks A  
and B.  
-
Engine oil level  
The check is carried out either when  
the ignition is switched on using the  
oil level indicator in the instrument  
panel for vehicles so equipped, or  
using the dipstick.  
Oil grade  
To ensure that the reading is correct,  
your vehicle must be parked on a level  
surface with the engine having been off  
for more than 30 minutes.  
Before topping-up the oil or changing the oil,  
check that the oil is the correct grade for your  
engine and conforms to the manufacturer's  
recommendations.  
A = MAX  
B = MIN  
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 kms).

Practical information  
Brake fluid level  
The brake fluid level should be close  
to the "MAX" mark. If it is not, check  
the brake pad wear.  
Topping-up the engine oil level  
Engine oil change  
F
Locate the oil filler cap in the engine  
compartment of your vehicle.  
Refer to the manufacturer's service schedule  
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.  
For more information on the petrol or Diesel  
engine, refer to the corresponding section.  
Changing the fluid  
Refer to the manufacturer's service schedule  
for details of the interval for this operation.

Unscrew the oil filler cap to reveal the filler  
aperture.  
Add oil in small quantities, avoiding any  
spills on engine components (risk of fire).  
Wait a few minutes before checking the  
level again using the dipstick.

Add more oil if necessary.  
After checking the level, carefully refit the  
oil filler cap and the dipstick in its tube.  
The brake fluid must conform to the  
manufacturer's recommendations.

Power steering  
fluid level  
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.  
The power steering fluid level should  
be close to the "MAX" mark. With  
the engine cold, unscrew the cap to  
check the level.  
227  
Practical information  
Coolant level  
Screenwash / headlamp  
wash fluid level  
The coolant level should be close  
to the "MAX" mark but should never  
exceed it.  
To check the level or top up the  
fluid on vehicle fitted with headlamp  
washers, immobilise the vehicle and  
switch of the engine.  
F
F
Top up if necessary.  
Refit the filler cap to the reservoir and  
close the bonnet.  
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 pressure to drop.  
When the pressure has dropped, remove the  
cap and top up the level.  
Specification of the fluid  
To ensure optimum cleaning and to avoid  
freezing, the fluid should never be topped up or  
replaced by plain water.  
In wintry conditions, the use of a fluid  
with an ethyl alcohol or methanol base is  
recommended.  
Fluid specification  
The coolant must conform to the  
manufacturer's recommendations.  
F
Open the bonnet and secure it with the  
stay.  
F
F
Open the screenwash reservoir filler cap.  
Take and pinch the level gauge to block its  
breather.  
Remove the gauge completely from  
the reservoir to read the level in the  
transparent section.  
The cooling fan may start after  
switching off the engine: take care  
with articles and clothing that might  
be caught by the fan blades.
