Recommendations for recommended lubricants The oils which appear in the table opposite are suitable for most pur-poses. The diagram opposite states the optimum range of viscosity depend-ing on the temperatures at which theoils are to be used. It is also possible to use synthetic oils of `superior quality'. In the absence of semi-synthetic or
synthetic oils, oils of API SH/SJ qual-ity (for petrol engines), or CD/CFquality (for diesel engines) may beused by following the 'Arduous Con-ditions' servicing schedule, whichspecifies shorter service intervals. Do not hesitate to ask for advice
from a PEUGEOT dealer to maintaindriving pleasure and to minimise themaintenance cost of your vehicle. For countries outside Europe, please
contact a local PEUGEOT dealer.

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 warning lights may
be linked to buzzers and a message on the multifunction display. Do notignore this warning: contact a PEUGEOT dealer as quickly as possible.
If the Central (STOP) warning light comes on when you are driving, 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 level", "the coolant temperature gauge" and "electronic brake force distributionsystem 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:
Ð insufficient oil pressure,
Ð lack of oil in the lubrication circuit. Top up the oil level.
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 thecap to the first notch to allow thepressure 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 Oil levelCheck 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 coldusing the oil gauge or the dipstick.Dipstick There are two marks on the dipstick: A= maximum
Never fill past this mark. B = minimum
To maintain the reliability of the engines and of theemission control systems,the use of additives in theengine oil is prohibited.
Oil change According to the information given in
"PEUGEOT SERVICING" .
Note: avoid any prolonged contact of
used oil with the skin.
Viscosity selection In all cases, the oil selected must meet the manufacturer's require-ments.

Brakes and clutch level:
Ð The level should always be
between the DANGER and MAX
marks on the reservoir.
Ð If the level drops substantially, con- tact a PEUGEOT dealer imme-
diately.
Fluid change:
Ð must be carried out according to the manufacturer's servicing schedule.
Ð use fluids recommended by the manufacturer, which fulfil DOT 4standards.
Note: the brake fluid is noxious and
very corrosive. Avoid any contactwith the skin. Coolant level Use the fluid recommended by the
manufacturer. When the engine is warm, the tem- perature of the coolant is controlledby the engine fan. Because this fan
can operate with the ignition off andbecause the cooling system is pres-surised, wait for at least one hourafter the engine has stopped beforecarrying out any work. To avoid any risk of burns, slackenthe cap to the first notch to releasethe pressure. When the pressure hasdropped, remove the cap and top upthe level. Used productsDo not dispose of used oil, brake fluid or coolant down drains or on theground. Power steering fluid level Open the reservoir with the engine
cold. The level should always beabove the MINI mark, close to theMAXI mark.
Windscreen and headlamp* wash fluid level For best quality cleaning and for your
safety, we recommend that you use
products recommended by PEUGEOT.
* According to destination.

TOWING A TRAILER,
CARAVAN, BOAT ETC.
Only use original PEUGEOT tow bars that have been tested andapproved from the design stage ofyour vehicle. The tow bar must be fitted by a
PEUGEOT dealer.
Your vehicle is basically designed for transporting people and luggage butit may also be used for towing a
trailer. Driving with a trailer subjects the towing vehicle to more significantstress 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
1 000 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 theaxle and the nose weight approach-es the maximum permitted withoutexceeding it. Cooling:
Towing a trailer on a slope
increases the temperature of thecoolant. As the fan is electrically controlled, its cooling capacity is not dependenton the engine speed.
On the contrary, use a high gear to lower the engine speed, and reduceyour speed. The maximum towing speed on a long slope depends on the gradientand the outside temperature. For vehicles fitted with a direct injec- tion petrol engine, after towing or dri-ving at high speed for a long periodof time, the fan may operate forapproximately 6 minutes. In all cases, pay attention to the coolant temperature. If the warning light comes on, stop
the vehicle and switch off the engineas soon as possible. Tyres:
Check the tyre pressures of
the towing vehicle and the trailer,observing the recommended pres-sures. Brakes: Towing increases the braking
distance. Lights: Check the electrical sig-
nalling on the trailer.Side wind: Take into acount the
increased sensitivity to side wind.
