2002.5 Peugeot 406 cooling

WARNING LIGHTS AND INDICATORS
A permanently lit warning light, or flashing with the engine running, is an
indication of a malfunction in the relevant unit. Some warn ing lights may
be linked to buzzers and a message on the multi–function display. Do n ot
ignore this warning: contact a PEUGEOT dealer as quickly a s possible.
If the Central (STOP) warning light comes on when you are d riving, stop
your vehicle immediately where it is safe to do so.
Central (STOP) warning light
Linked to the "engine oil pressure", ''the low brake fluid l evel'', '' the
coolant temperature gauge'' and ''electronic brake force distrib u
tion system fault'' warning lights.
It comes on each time the ignition is switched on.
Stop immediately if it flashes with the engine running.
Contact a PEUGEOT dealer.
Engine oil pressure warning light
Linked to the central (STOP) warning light.
Stop immediately if it comes on with the engine running.
It indicates either:
– insufficient oil pressure,
– lack of oil in the lubrication circuit. Top up the oil le vel.
Contact a PEUGEOT dealer as soon as possible. Low coolant level
warning light
Stop immediately.
Allow the engine to cool before top
ping up.
The cooling system is pressurised.
In the event of a breakdown and to
prevent the risk of scalding, turn the
cap to the first notch to allow the
pressure to drop.
Once the pressure has dropped,
remove the cap and top up the level.
Contact a PEUGEOT dealer.
Fuel filler cap warning
light
This comes on if the fuel
cap is not correctly screwed
on or is missing.

CHECKING THE LEVELS
Engine
Checking the oil level
Check the level regularly and top up
between changes. Maximum con
sumption is 0.5 litres per 600 miles
(1 000 km).
The oil level should be checked with
the vehicle level and the engine cold.There are two marks on
the dipstick:
A= maximum
B = minimum
Oil change: according to the manu
facturer's servicing schedule.
Dipstick. Never fill past the maxi mum mark A.
Oil level gauge on the instrument panel.
Viscosity selection
In all cases, the oil selected must
meet the manufacturer's require
ments.

Oil filter
Change the filter regularly according
to the servicing schedule.
Used oil
Prevent used oil from coming into
prolonged contact with the skin.
Do not dispose of used oil into drains
or onto the ground.
To maintain the reliability of engines
and emission control systems, the
use of additives in the engine oil is
prohibited.
Brakes and clutch
Checking the brake and clutch
fluid level:
The level should always be above
the DANGER mark on the reser
voir.
If the level drops substantially, con tact a PEUGEOT dealer imme
diately.
Fluid change
must be carried out according to the manufacturer's servicing
schedule.
use fluids approved by the manu facturer, which fulfil DOT 4 stan
dards. Cooling system
Use the fluid approved by the manu
facturer.
When the engine is warm, the tem
perature of the coolant is controlled
by the engine fan. Because this fan
can operate with the ignition key
removed and because the cooling
system is pressurised, wait for at
least one hour after the engine has
stopped before carrying out any
work.
In the event of a breakdown and to
avoid any risk of burns, slacken the
cap to the first notch to release the
pressure. When the pressure has
dropped, remove the cap and top up
the level.

TOWING A TRAILER,
CARAVAN, BOAT ETC.
Only use original PEUGEOT tow
bars that have been tested and
approved from the design stage of
your vehicle.
The tow bar must be fitted by a
PEUGEOT dealer.
Your vehicle is basically designed for
transporting people and luggage but
it may also be used for towing a
trailer.
Driving with a trailer subjects the
towing vehicle to more significant
stress and its driver must be particu
larly careful.
Air density decreases with altitude,
thus reducing engine performance.
The maximum towing load must
be reduced by 10% for every
1000 metres of altitude.
Driving advice
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. 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.
On the contrary, use a high gear to
lower the engine speed, and reduce
your speed.
The maximum towing speed on a
long slope depends on the gradient
and the outside temperature.
For vehicles fitted with a direct injec
tion petrol engine, after towing or dri
ving at high speed for a long period
of time, the fan may operate for
approximately 6 minutes.
In all cases, pay attention to the
coolant temperature.
If the warning light comes on, stop
the vehicle and switch off the engine
as soon as possible.
Tyres:
Check the tyre pressures of the tow
ing vehicle and the trailer, observing
the recommended pressures.
Brakes:
Towing increases the braking distance.
Lights:
Check the electrical signalling on the
trailer.
Side wind:
Take into acount the increased sen
sitivity to side wind.
