CHECKS





































CHECKING LEVELS

Check all of these levels regularly and
top them up if necessary, unless other-
wise indicated.
If a level drops signifi cantly, have the
corresponding system checked by a
PEUGEOT dealer or a qualifi ed work-
shop.

Brake fluid level

When the engine is warm, the tempera-
ture of the coolant is regulated by the fan.
This can operate with the ignition off.

On vehicles which are fi tted with a
particle emission fi lter, the fan may
operate after the vehicle has been
switched off, even if the engine is
cold.

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.

Oil level

The check is carried out either when
the ignition is switched on using the
oil level indicator on the instrument
panel, or using the dipstick.
This manual check will only be correct if the
vehicle is on level ground and the engine
has been off for more than 30 minutes.
After topping up the oil, the check when
switching on the ignition with the oil level
indicator in the instrument panel will only
be valid 30 minutes after topping up. 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 servicing booklet for details
of the interval for this operation.


Power steering fluid level

The power steering fl uid level
should be close to the "MAX"
mark. Unscrew the cap, with the
engine cold, to check the level.


Screenwash and headlamp
wash fluid
In the case of vehicles fi tted
with headlamp washers, the
low fl uid level is indicated by an
audible signal and a message
in the instrument panel screen.
Top up the reservoir when you stop the
vehicle.

Engine oil change
Refer to the servicing booklet for details
of the interval for this operation.
Oil specifi cation
The oil must be the correct grade for
your engine and conform to the manu-
facturer's recommendations.


Fluid specifi cation
The brake fl uid must conform to the
manufacturer's recommendations and
meet the DOT4 standard.

Changing the coolant
The coolant does not have to be
changed.

Fluid specifi cation
For optimum cleaning and to avoid
freezing, this fl uid must not be topped
up with or replaced with plain water.



Coolant level

The coolant level should be
close to the "MAX" mark but
should never exceed it.
Fluid specifi cation
The coolant must conform to the manu-
facturer's recommendations.

When working under the bon-
net, take care, as certain areas
of the engine may be extreme-
ly hot (risk of burns).

It is normal to top up the oil level
between services. PEUGEOT
recommends that you check
the oil level and top up if necessary ev-
ery 3 000 miles (5 000 kilometres). In order to maintain the reliability of the
engine and emission control system,
the use of additives in the engine oil is
prohibited.

172
CHECKS
Avoid prolonged contact of
used oil or fl uids with the skin.
Most of these fl uids are harm-
ful to health or indeed very corro-
sive.
Do not discard used oil or fl u-
ids into sewers or onto the
ground.
Take used oil to a PEUGEOT
dealer or a qualifi ed workshop
(France) or to an authorised waste
disposal site.










Diesel additive level (Diesel engine
with particle emission filter)
The additive reservoir low level is indi-
cated by fi xed illumination of this warn-
ing lamp, accompanied by an audible
warning and a message in the multi-
function screen.

PRACTICAL INFORMATION





TOWING A TRAILER,
A CARAVAN, ETC.
Your vehicle is primarily designed for
transporting people and luggage, but it
may also be used for towing a trailer.

Driving advice

The maximum towed load on a long in-
cline depends on the gradient and the
ambient temperature.
In all cases, keep a check on the cool-
ant temperature.

Side wind


)
Take into account the increased
sensitivity to side wind.


Cooling
Towing a trailer on a slope increases
the temperature of the coolant.
As the fan is electrically controlled, its
cooling capacity is not dependent on
the engine speed.


)
To lower the engine speed, reduce
your speed.
Braking
Towing a trailer increases the braking
distance.
To avoid overheating of the brakes on a
long mountain type of descent, the use
of engine braking is recommended.

Tyres


)
Check the tyre pressures of the towing
vehicle and of the trailer, observing the
recommended pressures.


Lighting


)
Check the electrical lighting and sig-
nalling on the trailer.
The rear parking sensors will
be deactivated automatically if
a genuine PEUGEOT towbar
is used.


)
If the warning lamp and the
STOP
warning lamp come
on, stop the vehicle and
switch off the engine as
soon as possible.

Towbar suitable for the attachment of a
trailer or caravan with additional lighting
and signalling.

Distribution of loads


)
Distribute the load in the trailer so
that the heaviest items are as close
as possible to the axle and the nose
weight approaches the maximum
permitted without exceeding it.
Air density decreases with altitude, thus
reducing engine performance. Above
1 000 metres, the maximum towed load
must be reduced by 10 % for every
1 000 metres of altitude. Driving with a trailer places greater de-
mands on the towing vehicle and the
driver must take particular care.
We recommend the use of
genuine PEUGEOT towbars
and their harnesses that have
been tested and approved from the
design stage of your vehicle, and that
the fi tting of the towbar is entrusted
to a PEUGEOT dealer or a qualifi ed
workshop.
If the towbar is not fi tted by a
PEUGEOT dealer, it is imperative
that it is fi tted in accordance with the
vehicle manufacturer's instructions. Refer to the "Technical Data"
section for details of the
weights and towed loads
which apply to your vehicle.

displayed...). The vehicle is too far from the transmitter used by the station listened
to or there is no transmitter in the geographical area through which the
vehicle is travelling. Activate the "RDS" function by means of the
short-cut menu to enable the system to check
whether there is a more powerful transmitter in the
geographical area.
The environment (hills, buildings, tunnels, basement car parks...) block
reception, including in RDS mode. This phenomenon is normal and does not indicate
a failure of the audio equipment.
The aerial is absent or has been damaged (for example when going
through a car wash or into an underground car park). Have the aerial checked by a PEUGEOT dealer.
Sound cut-outs of 1 to
2 seconds in radio mode. During this brief sound cut-out, the RDS searches for any frequency
permitting better reception of the station. Deactivate the "RDS" function by means of the
short-cut menu if the phenomenon is too frequent
and always on the same route.
With the engine off, the
system switches off after
a few minutes of use. When the engine is switched off, the system's operating time depends on
the battery charge.
The switch-off is normal: the system switches to economy mode and
switches off to prevent discharging of the vehicle's battery. Start the vehicle's engine to increase the battery
charge.
