Recommendations for approved 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 multi–function 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 distribu-tion system fault'' warning lights. It comes on each time the igni-
tion 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 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 case of overheating, to prevent the risk of scalding, turn the cap tothe first notch to allow the pressureto 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.

Door open warning light
When the engine is running, the warning light indicates that a door has not beenclosed properly or that the
boot is open.
Electronic immobiliser warning light This indicates a malfunction of the electronic immobilis-
er. Contact a PEUGEOT dealer.
Low fuel level warning light. When the warning light comes on, you have
enough fuel to drive at least 30 miles
(50 km). The tank capacity is approx-imately 70 litres (15.4 gallons). Coolant temperature indicator When the needle is in zone
A,the
temperature is correct. When the needle is in zone B, the
temperature is too high. The central
(STOP) warning light flashes.
You must stop immediately.
Contact a PEUGEOT dealer.
Seat belt not fastened warning light With the engine running, the indicator light comes onwhen the driver's seat belt isnot fastened.

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 but it
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 mustbe 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 possi-ble to the axle and the nose weightapproaches the maximum permittedwithout exceeding 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 brak-
ing distance. Lights: Check the electrical sig-
nalling on the trailer.Side wind: Take into acount the
increased sensitivity to side wind.
