ignition is switched on (for vehicles equipped
with an electric gauge), or using the dipstick.
It is normal to top up the oil level between two
services (or oil changes). It is recommended
that you check the level, and top up if necessary,
every 3,000 miles (5,000 km).
In order to maintain the reliability of the
engine and emissions control system,
never use additives in the engine oil.
Checking using the dipstick
For the location of the dipstick, please refer
to the illustration of the corresponding engine
compartment.

T
op up the level if necessary.
►

After checking the level, carefully screw the
oil filler cap back on

and replace the dipstick in
its tube.
The oil level indication displayed on the instrument panel when the ignition is
switched on is not valid for 30 minutes
following an addition of oil.
Brake fluid
The level of this fluid should be close to the "MAX" mark. If not, check the brake
pads for wear.
To know how often the brake fluid should be
replaced, refer to the manufacturer's servicing
schedule.
Clean the cap before removing it to refill.
Use only DOT4 brake fluid from a sealed
container.
Engine coolant
It is normal to top up this fluid between
two services.
The check and top-up must only be done with
the engine cold.
A level of coolant that is too low risks causing
major damage to the engine; the coolant level
must be close to the "MAX" mark without ever
going above it.
If the level is close to or below the " MIN” mark, it
is essential to top up.
When the engine is hot, the temperature of the
coolant is regulated by the fan.
As the cooling system is pressurised, wait at
least one hour after switching off the engine
before carrying out any work.
In order to avoid the risk of scalding if you need
to top up in an emergency, wrap a cloth around
the cap and unscrew the cap by two turns to
allow the pressure to drop.
