Warning lamps
When the engine is running or the vehicle is being driven, illumination of one of the following warning lamps indicates a fault which requires action on the part of the driver. Any fault resulting in the illumination of a warning lamp must be investigated further using the associated message. If you encounter any problems, contact a PEUGEOT dealer or a qualified workshop.
Warning / indicator lampStateCauseAction / Observations
STOP fixed, associated with another warning lamp, accompanied by an audible signal and a message.
Illumination of this warning lamp is related to a serious fault detected with the braking or power steering systems, the electrical system, or with engine lubrication or cooling or a puncture.
Stop as soon as it is safe to do so as the engine may cut out. Park, switch off the ignition and call a PEUGEOT dealer or a qualified workshop.

Coolant temperature gauge
With the engine running, when the needle is: - in zone A , the temperature is correct, - in zone B , the temperature is too high; the maximum temperature and the central STOP warning lamps come on, accompanied by an audible signal and a warning message in the screen. You MUST stop as soon as it is safe to do so. Wait a few minutes before switching off the engine. Contact a PEUGEOT dealer or a qualified workshop.
After driving for a few minutes, the temperature and pressure in the cooling system increase. To top up the level:  wait for the engine to cool,  unscrew the cap slightly to allow the pressure to drop,  when the pressure has dropped, remove the cap,  top up the level to the "MA X" mark.
Be aware of the risk of burns when topping up the cooling system. Do not fill above the maximum level (indicated on the header tank).

Very cold climate screen
Before fitting or removing the screen, ensure that the engine is off and the cooling fan has stopped. It is recommended that the screen be fitted and removed by a PEUGEOT dealer or a qualified workshop.
Fitting
 Offer up the screen to the front of the top section of the front bumper upper grille.  Press on the screen to engage its fixing clips.
Removal
 Use a screwdriver as a lever to unclip each retaining clip in turn.
Do not forget to remove the very cold climate screen: - when the ambient temperature exceeds 10° C (for example: in summer, ...), - when towing, - at speeds above 75 mph (120 km/h).
Removable protective screen which prevents the accumulation of snow at the radiator cooling fan.

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. 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.
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. The maximum towed load on a long incline depends on the gradient and the ambient temperature. In all cases, keep a check on the coolant temperature.
 If the warning lamp and the STOP warning lamp come on, stop the vehicle and switch off the engine as soon as possible.
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.
Ty r e s
 Check the tyre pressures of the towing vehicle and of the trailer, observing the recommended pressures.
Lighting
 Check the electrical lighting and signalling on the trailer.
The rear parking sensors will be deactivated automatically if a genuine PEUGEOT towbar is used.
Refer to the "Technical data" section for details of the weights and towed loads which apply to your vehicle.

Checks
308_EN_CHAP08_VERIFICATIONS_ED02-2013
Checking levels
Take care when working under the bonnet, as certain areas of the engine may be extremely hot (risk of burns) and the cooling fan could start at any time (even with the ignition off).
Oil level
The check is carried out either when the ignition is switched on using the oil level indicator in the instrument panel, or using the dipstick.
Engine oil change
Refer to the warranty and maintenance record for details of the interval for this operation. In order to maintain the reliability of the engine and emission control system, the use of additives in the engine oil is prohibited.
Oil specifi cation
The oil must be the correct grade for your engine and conform to the manufacturer's recommendations.
Check all of these levels regularly, in line with the warranty and maintenance record. Top them up if necessary, unless other wise indicated. If a level drops significantly, have the corresponding system checked by a PEUGEOT dealer or a qualified workshop.
Dipstick
There are two marks on the dipstick:
A = maximum If the level is above this mark, contact a PEUGEOT dealer or a qualified workshop. B = minimum Top up the level through the oil filler orifice, using the correct grade of oil for your engine. The level must never be below this mark.
It will only be correct if the vehicle is on level ground and the engine has been off for more than 30 minutes. It is normal to top up the oil level between two services (or oil changes). PEUGEOT recommends that you check the level, and top up if necessary, every 3 000 miles (5 000 kms). After topping up the oil, the check when switching on the ignition with the oil level indicator in the instrument panel is not valid during the 30 minutes after topping up.

Checks

The brake fluid level must be between the marking " A " (MA X A " (MA X Alocated on the remote reservoir) and the marking " B " (MIN located on the main reservoir). If it is not, check the brake pad wear.
Brake fluid level
Changing the fl uid
Refer to the warranty and maintenance record for details of the interval for this operation.
Fluid specifi cation
The brake fluid must conform to the manufacturer's recommendations.
Coolant level
The coolant level should be close to the "MA X" mark but should never exceed it.
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 pressure to drop. When the pressure has dropped, remove the cap and top up the level.
Changing the coolant
The coolant does not have to be replaced at routine services.
Fluid specifi cation
The coolant must conform to the manufacturer's recommendations.
The cooling fan may star t after switching off the engine: take care with ar ticles and clothing that might become caught by the fan blades.
When the engine is warm, the temperature of the coolant is regulated by the fan.
