Get Driving -> Starting/Switching off the engine with Keyless Entry and Start Guide for Peugeot 308 4 Door 2021-2025

Driving

Tyres

Brakes

Towing

► Check the tyre pressures of the towing

vehicle and of the trailer, observing the

recommended pressures.

Using the engine brake is recommended to limit

the overheating of the brakes. Braking distances

are increased when towing a trailer.

Driving with a trailer places greater

demands on the towing vehicle and

particular care must be taken.

Lighting

Side wind

► Check the electrical signalling on the trailer

and the headlamp beam height of your vehicle.

Bear in mind that the vehicle will be more

susceptible to wind when towing.

Do not exceed the maximum towable

weights.

At altitude: reduce the maximum load by

10% per 1,000 metres of altitude; the lower

air density at high altitudes decreases engine

performance.

If a genuine PEUGEOT towing device is

used, the rear parking sensors will be

deactivated automatically to avoid the audible

signal.

Anti-theft protection

Electronic immobiliser

The keys contain a code, which must be

recognised by the vehicle before starting is

possible.

If the system malfunctions, indicated by the

display of a message, the engine will not start.

Contact a PEUGEOT dealer.

New vehicle: do not tow a trailer until the

vehicle has driven at least 620 miles

(1,000 kilometres).

When driving

Cooling

Towing a trailer uphill causes the coolant

temperature to increase. The maximum towable

load depends on the gradient and the exterior

temperature. The fan’s cooling capacity does not

increase with engine speed.

If the outside temperature is high, let the

engine idle for 1 to 2 minutes after the

vehicle comes to a stop, to help it to cool.

► Reduce speed and lower the engine speed to

limit the amount of heating produced.

► Pay constant attention to the coolant

temperature.

If this warning lamp and the STOP

warning lamp come on, stop the

vehicle and switch oﬀ the engine as soon as

possible.

Before setting oﬀ

Nose weight

► Distribute the load in the trailer so that the

heaviest items are as close as possible to the

axle and the nose weight (at the point where it

joins your vehicle) approaches the maximum

permitted without exceeding it.

Driving

Ignition on position

vibrations, for anything up to 2 minutes

(accelerated idle speed).

Starting / Switching oﬀ the

engine with the key

It allows the use of the vehicle's electric

equipment or the charging of accessories.

Once the state of charge of the battery drops to

the reserve level, the system switches to energy

economy mode. The power supply is cut oﬀ

automatically to preserve the remaining battery

charge.

► With a Diesel engine, turn the key to position

2, to activate the engine preheating system.

Wait until this warning lamp goes oﬀ on

the instrument panel, then turn the key to

to operate the starter motor. Once the engine

has started, release the key and allow it to return

to position 2.

again. If the engine does not start after a few

attempts, do not keep trying - risk of

damaging the starter motor and the engine!

Contact a PEUGEOT dealer or a qualiﬁed

workshop.

► With a petrol engine, operate the starter

motor by turning the key to position 3 without

pressing the accelerator pedal, until the engine

starts. Once the engine has started, release the

key and allow it to return to position 2.

Avoid attaching heavy objects to the key

or the remote control. This would weigh

down on its shaft in the ignition switch and

could cause a malfunction.
