– Jolting and knocking noise during hill starts.  
Tyres  
Side wind  
►ꢀ Check the tyre pressures of the towing vehicle  
and of the trailer, observing the recommended  
pressures.  
Bear in mind that the vehicle will be more  
susceptible to wind when towing.  
Towing  
Driving with a trailer places greater  
demands on the towing vehicle and  
particular care must be taken.  
Lighting  
Anti-theft protection  
►ꢀ Check the electrical signalling on the trailer  
and the headlamp beam height of your vehicle.  
Electronic immobiliser  
The keys include an electronic engine immobiliser  
system, with a code that must be recognised in  
order for starting to be possible.  
Do not exceed the maximum towable  
weights.  
If a genuine towing device is used, the  
rear parking sensors will be deactivated  
automatically to avoid the audible signal.  
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 the system malfunctions, indicated by the  
display of a message, the engine will not start.  
Contact a dealer.  
When driving  
Cooling  
New vehicle: do not tow a trailer until the  
vehicle has driven at least 620 miles  
(1,000 kilometres).  
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.  
►ꢀ Reduce speed and lower the engine speed to  
limit heating up.  
In all cases, pay 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.  
Starting/Switching off the  
engine  
The electronic key must be present in the  
passenger compartment.  
For versions equipped with Proximity Keyless  
Entry and Start, the electronic key is also  
detected in the boot.  
If it is not detected, a message is displayed.  
Move the electronic key so that the engine can  
be started or switched off.  
If there is still a problem, refer to the "Key not  
detected - Back-up starting or Back-up switch-  
off" section.  
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.  
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.  
Brakes  
Braking distances are increased when towing a  
trailer. To avoid overheating the brakes, the use of  
engine braking is recommended.

The lighting state of the "START/STOP"  
button indicates the presence or absence  
of the electronic key in the passenger  
compartment.  
With petrol engines, after a cold start,  
preheating the catalytic converter can  
cause noticeable engine vibrations for  
anything up to 2 minutes while stationary with  
the engine running (accelerated idle speed).  
Starting/Switching off the  
electric motor  
Starting  
The drive selector must be in mode P.  
►ꢀ Fully depress the brake pedal and briefly press  
the "START/STOP" button.  
►ꢀ Keep your foot on the brake pedal until the  
READY indicator lamp comes on and an audible  
signal is emitted, indicating that the vehicle is  
ready to drive.  
►ꢀ With your foot on the brake, press the  
"Unlock" button and select mode D/B or R.  
►ꢀ Release the brake pedal, then accelerate.  
On starting, the instrument panel lights up and  
the power indicator cursor moves to the "neutral"  
position. The steering column automatically  
unlocks (you may hear a sound and feel the  
steering wheel move).  
Starting  
If the engine stalls, release the clutch  
pedal and fully depress it again, the  
engine will restart automatically.  
►ꢀ With a manual gearbox, place the gear lever in  
neutral and fully depress the clutch pedal.  
►ꢀ With an automatic gearbox, select mode P  
or N and press the brake pedal.  
Switching off  
►ꢀ Immobilise the vehicle, with the engine at idle.  
►ꢀ With a manual gearbox, ideally put the gear  
lever into neutral.  
►ꢀ With an automatic gearbox, ideally select  
mode P or N.  
►ꢀ Press the "START/STOP" button..  
In some circumstances, it is necessary to turn the  
steering wheel to lock the steering column.  
►ꢀ Press the "START/STOP" button while  
maintaining pressure on the pedal until the engine  
starts.  
For Diesel engines, when the temperature is below  
zero and/or the engine is cold, starting will only  
occur once the preheating warning lamp is off.  
If this warning lamp comes on after  
pressing the "START/STOP" button:  
►ꢀ Keep the pedal fully depressed and do not  
press the "START/STOP" button again until the  
engine is running.  
If one of the starting conditions is not met, a  
message is displayed.  
Switching off  
If the vehicle is not immobilised, the  
engine will not switch off.  
►ꢀ Press the "START/STOP" button.  
Before exiting the vehicle, check that:  
– The drive selector is in mode P.  
– The READY indicator lamp is off.  
With the engine off, the braking and  
steering assistance systems are also cut  
off - risk of loss of control of the vehicle!  
If the driver's door is opened while the  
required conditions for stopping are not  
satisfied, an audible signal is emitted,  
accompanied by the display of a warning  
message.  
Never leave your vehicle with the  
electronic key still inside.  
In some circumstances, a message indicates  
that it is necessary to turn the steering wheel  
while pressing the "START/STOP" button to assist  
unlocking of the steering column.

The engine starts.  
Switching on the ignition

With the electronic key in the passenger  
compartment, pressing the “START/STOP” button,  
without pressing any of the pedals, allows the

engine.  
Starting/Switching off  
Back-up switch-off  
the engine with DS SMART  
ACCESS  
After activation by the customer, this function  
makes it possible, via the MyDS application, to  
access the vehicle, to start it and to delegate its  
use to people of their choice.  
►ꢀ Press this button again to switch off the  
ignition and allow the vehicle to be locked.  
For more information on DS SMART ACCESS and  
its activation, install the MyDS application and  
refer to the corresponding section.  
Key not detected  
Back-up starting  
Electric parking brake  
In automatic mode, this system applies the  
parking brake when the engine is switched off  
and releases it when the vehicle moves off.  
A back-up reader is fitted to the steering column,  
to enable the engine to be started if the system  
fails to detect the key in the recognition zone, or if  
the battery in the electronic key is discharged.  
If the electronic key is not detected or is no longer  
in the recognition zone, a message appears in the  
instrument panel when closing a door or trying to  
switch off the engine.  
►ꢀ To confirm the instruction to switch off the  
engine, press the "START/STOP" button for  
approximately 5 seconds.  
In the event of a fault with the electronic key,  
contact a dealer or a qualified workshop.  
Emergency switch-off  
In the event of an emergency only, the engine can  
be switched off without conditions (even when  
driving).  
►ꢀ Place and hold the remote control against the  
reader.  
At any time, with the engine running:  
►ꢀ to apply the parking brake, briefly pull the  
control lever;  
►ꢀ to release it, briefly push the control lever  
while pressing the brake pedal.  
►ꢀ With a manual gearbox, place the gear lever in  
neutral, then fully depress the clutch pedal.  
►ꢀ With an automatic gearbox or a drive selector,  
select mode P, then fully depress the brake pedal.  
►ꢀ Press the "START/STOP" button.  
►ꢀ Press the "START/STOP" button for about  
5 seconds.  
In this case, the steering column locks as soon as  
the vehicle stops.  
Automatic mode is activated by default.
