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.

CHECKING THE LEVELS Engine Checking the oil levelCheck the level regularly and top up between changes. Maximumconsumption is 0.5 litres per600 miles (1 000 km). The oil level should be checked with the vehicle level and the engine cold.There are two marks onthe 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 oilPrevent 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, theuse of additives in the engine oil isprohibited. 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, contact a PEUGEOT dealer imme-
diately.
Fluid change
- must be carried out according to the manufacturer's servicing sche- dule.
- 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 controlledby the engine fan. Because this fancan operate with the ignition keyremoved and because the coolingsystem is pressurised, wait for atleast one hour after the engine hasstopped before carrying out anywork. In the event of a breakdown and to avoid any risk of burns, slacken thecap to the first notch to release thepressure. When the pressure hasdropped, remove the cap and top upthe level.

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.
