DRIVING

Driving recommendations
Observe the driving regulations and remain
vigilant whatever the traffic conditions.
Pay close attention to the traffic and keep your
hands on the wheel so that you are ready to
react at any time to any eventuality.
As a safety measure, the driver should only
carry out any operations that require close
attention when the vehicle is stationary.
On a long journey, a break every two hours is
strongly recommended.
In bad weather, drive smoothly, anticipate the
need to brake and increase the distance from
other vehicles.Never leave the engine running in
an enclosed area without adequate
ventilation: internal combustion engines
emit toxic exhaust gases, such as carbon
monoxide. There is a risk of poisoning and
death!
In very severe wintry conditions
(temperatures below -23°C), to guarantee
correct operation and the longevity of
the mechanical elements of your vehicle,
engine and gearbox, the engine must be
left running for 4 minutes before driving.
Important!
Never drive with the parking brake applied
– Risk of overheating and damage to the
braking system!
Do not park and do not run the engine,
the vehicle is stationary, in areas where
substances and combustible materials
(dry grass, leaves ...) can come into
contact with the hot exhaust system – Risk
of fire!
Never leave a vehicle unsuper vised with
the engine running. If you have to leave
your vehicle with the engine running, apply
the parking brake and put the gearbox into
neutral or position N or P , depending on
the type of gearbox.
Driving on flooded roads
We strongly advise against driving on flooded
roads, as this could cause serious damage
to the engine or gearbox, as well as to the
electrical systems of your vehicle. If you are obliged to drive through water:
-

c
heck that the depth of water does not
exceed 6 inches (15 cm), taking account
of waves that might be generated by other
users,
-
d
eactivate the Stop & Start function,
-
d
rive slowly as possible without stalling. In
every case, do not exceed a speed of 6 mph
(10 km/h),
-
d
o not stop and do not turn off the engine.
On leaving the flooded road, and as soon as
safety conditions permit, brake lightly several
times to dry the brake discs and pads.
If in doubt about the state of your vehicle,
contact the dealer network or a qualified
workshop.

Driving

133
In case of towing
Driving with a trailer places greater
demands on the towing vehicle and
requires extra care from the driver.
Distribution of loads
F 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. The maximum
towed load must be reduced by 10% for every
1,000 metres of altitude.
For more information on the Technical
data of your vehicle and particularly on
towable loads, refer to the corresponding
section.
If the exterior temperature is high, it is
recommended that the engine be allowed
to idle for 1 to 2 minutes after the vehicle
comes to a stop, to facilitate its cooling.
Side wind
F Take into account the increased sensitivity to 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.
F

T
o lower the engine speed, reduce your
speed.
The maximum towed load on a long incline
depends on the gradient and the exterior
temperature.
In all cases, keep a check on the coolant
temperature.
F

I
f this 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, the use of
engine braking is recommended.
Ty r e s
F Check the tyre pressures of the towing vehicle and of the trailer, observing the
recommended pressures.
Lighting
F Check the electrical lighting and signalling on the trailer and the headlamp beam height
of your vehicle.
For more information on Headlamp
adjustment , refer to the corresponding
section.
The rear parking sensors will be
deactivated automatically to avoid
the audible signal if a genuine DS
AUTOMOBILES towbar is used.

Anti-theft protection
Electronic immobiliser
The keys contain an electronic chip which has
a specific code. When the ignition is switched
on, this code must be recognised to allow the
engine to be started.
This electronic engine immobiliser locks the
engine management system a few minutes
after the ignition is switched off and prevents
starting of the engine by anyone who does not
have the key.In the event of a fault, you are
informed by illumination of this
warning lamp, an audible signal
and/or the display of a message,
depending on version.
Starting/Switching off the
engine with the key
Ignition switch
It has 3 positions:
- position 1 (Stop): inserting and removing
the key, steering column locked,
-
position 2 (Ignition on) : steering column
unlocked, ignition on, Diesel preheating,
engine running,
-
position 3 (Starting) .
Ignition on position
It allows the use of the vehicle's electric
equipment or portable devices to be charged.
Once the state of charge of the battery drops
to the reser ve level, the system switches to
energy economy mode: the power supply is
cut off automatically to preser ve the remaining
battery charge. Avoid attaching heavy objects to the key
or the remote control, which would weigh
down on its blade in the ignition switch
and could cause a malfunction.
Switching off the engine leads to a loss of
braking assistance.
Starting the engine
With the parking brake applied and the gearbox
in neutral or position N
or P:
F

d
epress the clutch pedal fully (manual
gearbox),
or
F

p
ress the brake pedal firmly (automatic
gearbox),
F

i
nsert the key into the ignition switch; the
system recognises the code,
F

u
nlock the steering column by simultaneously
turning the steering wheel and the key.
In certain cases, you may have to apply
more force to the steering (wheels on full
lock, for example).
F

W
ith 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 is
running, release the key.
In this case, your vehicle will not start; contact
the dealer network as soon as possible.
06
Driving

135
Wait until this warning lamp goes off in
the instrument panel then operate the
starter motor by turning the key to position
3 without pressing the accelerator pedal,
until the engine starts. Once the engine is
running, release the key.
In wintry conditions, the warning lamp
can stay on for a longer period. When the
engine is hot, the warning lamp does not
come on.
If the engine does not start straight away,
switch off the ignition. Wait a few moments
before operating the starter motor again.
If the engine does not start after several
attempts, do not keep trying: you risk
damaging the starter motor or the engine.
Contact the dealer network or a qualified
workshop.
In temperate conditions, do not leave
the engine at idle to warm up but move
off straight away and drive at moderate
spe ed. Never leave the engine running in
an enclosed area without adequate
ventilation: internal combustion engines
emit toxic exhaust gases, such as carbon
monoxide. Danger of poisoning and death!
In very severe wintry conditions
(temperature below -23°C), to guarantee
correct operation and the longevity of
the mechanical elements of your vehicle,
engine and gearbox, the engine must be
left running for 4 minutes before driving
away.
Switching off the engine
F Stop the vehicle.
F
W ith the engine idling, turn the key to
position 1 .
F

R
emove the key from the ignition switch.
F

T

steering wheel until it locks.
To facilitate unlocking of the steering
column, it is recommended that the
wheels be returned to the straight-ahead
position before switching off the engine. F

C
heck that the parking brake is correctly
applied, particularly on sloping ground.
Never switch off the ignition before the
vehicle is at a complete stop. With the
engine off, the braking and steering
assistance systems are also cut off: risk of
loss of control of the vehicle.
When you leave the vehicle, keep the key
with you and lock the vehicle.
F With a Diesel engine, turn the key to position 2, i
gnition on, to operate the engine
pre-heating system.
