Topping up the engine oil level
The location of the oil filler cap is shown in the
corresponding underbonnet layout view.
F
U
nscrew the oil filler cap to access the filler
opening.
F

A
dd oil in small quantities, avoiding any
spills on engine components (risk of fire).
F

W
ait a few minutes before checking the
level again using the dipstick.
F

A
dd more oil if necessary.
F

A
fter checking the level, carefully refit the oil
filler cap and the dipstick in its tube.
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
In order to maintain the reliability of the engine
and emissions control system, never use
additives in the engine oil.
Brake fluid level
The brake fluid level should be close
to the "MA X" mark. If it is not, check
the brake pad wear.
Changing the fluid
Refer to the manufacturer's service schedule
for details of the inter val for this operation.
Fluid specification
This fluid must conform to the manufacturer's
recommendations.
Coolant level
Check the coolant level regularly.
It is normal to top up the fluid
between two services. A low coolant level presents a risk of serious
damage to your engine.
The coolant level should be close to the "MA X"
mark but should never exceed 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.
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 the risk of scalding when you need to
top up in an emergency, place a cloth around
the cap and unscrew the cap by two turns to
allow the pressure to drop.
Once the pressure has dropped, remove the
cap and top up to the required level.
The cooling fan may star t after
switching off the engine: take care
with articles and clothing that might
be caught by the fan blades.Fluid specification
This fluid must conform to the manufacturer's
recommendations.
Oil grade
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.
The check and top up must only be done with
the engine cold.
Practical information

232
Air filter
Depending on the environment
(e.g. dusty atmosphere) and the
use of the vehicle (e.g. city driving),
replace it twice as often, if
necessary.
Oil filter
Change the oil filter each time the
engine oil is changed.
Particle filter (Diesel)
The start of saturation of the particle
filter is indicated by the temporary
illumination of this warning lamp
accompanied by a message about
the risk of the filter clogging up.
As soon as the traffic conditions permit,
regenerate the filter by driving at a speed
of at least 37
mph (60 km/h) until the
warning lamp goes off.
If the warning lamp stays on, this indicates
a low Diesel additive level.
For more information on Checking levels ,
refer to the corresponding section. On a new vehicle, the first particle
filter regeneration operations may be
accompanied by a "burning" smell, which
is per fectly normal.
Following prolonged operation of the
vehicle at very low speed or at idle,
you may, in exceptional circumstances,
notice the emission of water vapour at the
exhaust on acceleration. This does not
affect the behaviour of the vehicle or the
environment.
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 PEUGEOT
dealer or a qualified workshop.
Electric parking brake
This system does not require any
routine servicing. However, in the
event of a problem, have the system
checked by a PEUGEOT dealer or a
qualified workshop.
Practical information

233
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. 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.
Only use products recommended by
PEUGEOT or products of equivalent
quality and specification.
In order to optimise the operation of
components as important as those in the
braking system, PEUGEOT selects and
offers very specific products.
After washing the vehicle, dampness, or
in wintry conditions, ice can form on the
brake discs and pads: braking efficiency
may be reduced. Make light brake
applications to dry and defrost the brakes.
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.

Temporary puncture
repair kit
Scan the QR code on page 3 to view
explanatory videos.
Comprising a compressor and a sealant
cartridge, it allows the temporary repair of
a tyre so that you can drive to the nearest
garage.
It is designed to repair most punctures which
could affect the tyre, located on the tyre tread
or shoulder.
The vehicle's electric system allows the
connection of the compressor for long
enough to inflate a tyre after a puncture
repair.
Composition of the kit
1. 12 V compressor, with integral pressure
gauge.
2. Sealant cartridge, with integral hose.
3. Speed limit sticker.
Repair procedure
F Park the vehicle without obstructing any
traffic and apply the parking brake.
F

F

warning lamps, warning triangle, wearing
high visibility vest, etc.) according to the
legislation in force in the country where you
are driving.
F

S
witch off the ignition.
F

U
ncoil the pipe stowed under the
compressor.
For versions with a spare wheel:
5. Wheelbrace.
For removing the hub cap and removing
the wheel bolts.
6. Jack with integrated handle.
Used to raise the vehicle.
7. Wheel bolt cover remover (according to
equipment).
For removing the wheel bolt head
finishers on alloy wheels.

Parking the vehicle
Immobilise the vehicle where it does not
block traffic: the ground must be level,
stable and non-slippery.
Apply the parking brake, unless it is
programmed to be in automatic mode;
switch off the ignition and with a manual
gearbox, engage first gear so as to lock
the wheels.
Apply the parking brake, unless it is
programmed to be in automatic mode;
switch off the ignition and with an
automatic gearbox, select mode P so as
to lock the wheels.
Check that the parking brake warning
lamps in the instrument panel are on
fixed (not

flashing).
The occupants must get out of the
vehicle and wait where they are safe.
If necessary, place a chock under the
wheel diagonally opposite the wheel to
be changed.
Never go underneath a vehicle raised
using a jack; use an axle stand. F

T

After changing a wheel
Put the punctured wheel in the boot or,
depending on version, remove the central cover
first to store it beneath the floor in place of the
spare wheel.With a "space-saver" type spare wheel Visit a PEUGEOT dealer or a qualified
workshop as soon as possible to have the
tightness of the bolts and the pressure of
the spare wheel checked.
Have the punctured tyre examined. After
inspection, the technician will advise you
on whether the tyre can be repaired or if it
must be replaced.
