Limit the causes of excess
consumption
Spread loads throughout the vehicle; place
the heaviest items in the bottom of the boot,
as close as possible to the rear seats.
Limit the loads carried in the vehicle and
reduce wind resistance (roof bars, roof rack,
bicycle carrier, trailer...). Preferably, use a roof
box.
Remove roof bars and roof racks after use.
At the end of winter, remove snow tyres and
refit your summer tyres.
Observe the recommendations on
maintenance
Check the tyre pressures regularly, when cold,
referring to the label in the door aperture,
driver's side.
Carry out this check in particular:
-
b
efore a long journey,
-

a
t each change of season,
-

a
fter a long period out of use. Have your vehicle ser viced regularly (engine
oil, oil filter, air filter, cabin filter...) and
obser ve the schedule of operations in the
manufacturer's service schedule.
With a BlueHDi Diesel engine, if the SCR
system is faulty, your vehicle becomes
polluting. As soon as possible, visit a member
of the dealer network or a qualified workshop
to make your vehicle’s level of nitrogen oxides
emissions compliant to the standard.
When filling the tank, do not continue after the
3rd cut-off of the nozzle to avoid over flow.
At the wheel of your new vehicle, it is only
after around the first 1,900 miles (3,000
kilometres) that you will see the fuel
consumption settle down to a consistent
average. Do not forget the spare wheel and the tyres on
any trailer or caravan.

Tyre under-inflation
d
etection
The tyre under-inflation detection system
is an aid to driving which does not replace
the need for vigilance on the part of the
driver. This system does not avoid the need to
check the tyre pressures (including the
spare wheel) every month as well as
before a long journey.
Driving with under-inflated tyres worsens
road-holding, lengthens braking distances,
causes premature wear of the tyres,
particularly in adverse conditions (heavy
loads, high speeds, long journeys).
Driving with under-inflated tyres
increases fuel consumption.
The inflation pressures defined for your
vehicle can be found on the tyre pressure
label.
Tyre pressure should be checked when
the tyres are "cold" (vehicle stopped for
1 hour or after a journey of less than
6 miles (10 km) at moderate speeds).
Other wise, add 0.3 bar to the values
indicated on the label.
For more information on Identification
markings , including the tyre pressure
label, refer to the corresponding section.
Under-inflation alert
System which automatically checks the
pressures of the tyres while driving.
The system continuously monitors the
pressures of the four tyres, as soon as the
vehicle is moving.
A pressure sensor is located in the valve of
each tyre (except the spare wheel).
The system triggers an alert as soon as it
detects a drop in the inflation pressure of one
or more tyres. This warning is indicated by
continuous illumination of the lamp,
an audible signal and, depending on
the equipment installed, a message
displayed on the screen.
In the event of a problem on one of the tyres,
the symbol or the message appears, according
to equipment, to identify it.
F

R
educe speed immediately, avoid excessive
steering movements and sudden braking.
F

S
top as soon as it is safe to do so.
The loss of pressure detected does not
always cause visible bulging of the tyre.
Do not rely on just a visual check.

Driving

187
Observe the following recommendations to
avoid damaging the paint finish:
-
N
ever clean the vehicle without water.
-

N
ever clean your vehicle in an
automatic roller-brush car wash.
-

N
ever select the programme with hot
wax finish.
-

N
ever use a high pressure jet washer
fitted with a brush as this may scratch
the paint sur face.
-

N
ever polish the body or the alloy
wheels. This makes the paint bright.
-

D
o not use paint restorers, abrasive
or polishing products, or bright paint
preser vers (wax polish, for example).
These products are only suitable for
bright finishes. Using them on vehicles
finished with matt paint seriously
damages the sur face finish of the
vehicle, resulting in particular in the
appearance of irreversible bright or
stained areas. It is always preferable to have paint
repairs carried out in the dealer network or
by a qualified workshop.
Leather
Leather is a natural product. Appropriate
regular care and cleaning is essential for its
durability.
Refer to your vehicle's Maintenance and
Warranty Guide for information on all the
special precautions to observe.
In addition:
-

C

hoose a high pressure wash, or at least a
high-flow water jet.
-
R

inse the vehicle with demineralised water.
-

G

ently wipe the body with a clean
microfibre cloth.
-

C

arefully wipe off any fuel spilt on the body
using a soft cloth, then allow to dry.
-
C
lean off minor marks (for example, finger
marks), using the maintenance product
recommended by DS AUTOMOBILES.

Practical information

222
Identification markings
Various visible markings for the identification of
your vehicle.
A. Vehicle identification number (V.I.N.),
under the bonnet.
The number is engraved on the body structure.
B. Vehicle identification number (V.I.N.), on
the dashboard.
The number is on a label, visible through the
windscreen. C. Manufacturer's label.
This tamperproof label is affixed to the driver's
door aperture.
It bears the following information:
-

t
he name of the manufacturer,
-

t
he European Whole Vehicle Type Approval
number,
-

t
he vehicle identification number (V.I.N.),
-

t
he gross vehicle weight (GV W)
-

t
he maximum authorised vehicle + trailer
weight (the Gross Train Weight or GTW),
-

t
he maximum weight on the front axle,
-

t
he maximum weight on the rear axle.
D. Tyres/paint code label.
This label is affixed to the driver's door
aperture.
It bears the following information on the tyres:
-

t
he tyre pressures, unladen and laden,
-

t
he tyre specification, made up of the
dimensions and type as well as the load and
speed indices,
-

t
he spare tyre pressure.
It also indicates the paint colour code. The vehicle may be originally equipped
with tyres with higher load and speed
indices than those indicated on the label,
without affecting inflation pressure.
Checking tyre pressures
The tyre pressures should be checked when
cold at least monthly.
The pressures given on the label are valid for
cold tyres. If you have driven for more than 10
minutes or more than 6 miles (10 kilometres)
at more than around 30 mph (50 km/h), the
tyres will be warm; in this case 0.3 bar (30 kPa)
should be added to the pressures given on the
label. Never reduce the pressure of a warm tyre.
Low tyre pressures increase fuel
consumption.
