In case of towing
Driving with a trailer places greater
d emands 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.
Please respect the maximum towable
weights.
Side wind
F Take into account the increased sensitivity to wind.
Cooling
Towing a trailer on a slope increases the
t emperature 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 towable load on an 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.
New vehicle
Do not pull a trailer before having driven at least
approximately 600


miles (1,000

kilometres).
Braking
Towing a trailer increases the braking distance.
T o 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
beam height 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.
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.

Energy economy mode
System which manages the duration of use of
certain functions to conser ve a sufficient level
of charge in the battery.
After the engine has stopped, you can still
use functions such as the audio equipment,
windscreen wipers, dipped beam headlamps,
courtesy lamps, etc. for a
maximum combined
period of thirty minutes.
This period may be greatly reduced if the
battery is not fully charged.
Switching to this mode
Once this period has elapsed, a message
appears in the screen indicating that the
vehicle has switched to economy mode and the
active functions are put on standby.
Exiting the mode
These functions are reactivated automatically
next time the vehicle is driven.
F

T
o restore these functions immediately, start
the engine and let it run briefly. If the telephone is being used at the same
time, it will be interrupted after 10
minutes.The engine will not start if the battery is
discharged.
The time available to you will then be double
the period for which the engine is left running.
However, this period will always be between
five and thirty minutes.

Checking levels
Check all of these levels regularly, in line with
the manufacturer's service schedule. Top them
up if necessary, unless other wise indicated.
If a level drops significantly, have the
corresponding system checked by the dealer
network or a
qualified workshop.
The liquids must comply with the
manufacturer's recommendations and with
the vehicle's engine. 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).
Used products
Avoid prolonged contact of used oil or
fluids with the skin.
Most of these fluids are harmful to health
or indeed very corrosive.
Do not discard used oil or fluids into
sewers or onto the ground.
Return used oil to the dealer network or
a
qualified workshop and dispose of it in
the containers reser ved for this purpose.
Engine oil level
The check is carried out either when
the ignition is switched on using the
oil level indicator in the instrument
panel for vehicles equipped with an
electric gauge, or using the dipstick. To ensure that the reading is correct, your
vehicle must be parked on a
level sur face
with the engine stopped for more than
30

minutes.
It is normal to top up the oil level between two
ser vices (or oil changes). We recommend that
you check the level, and top up if necessary,
every 3,000 miles (5,000 km).
Checking using the dipstick

Topping up the engine oil level
The location of the oil filler cap is shown in the
corresponding underbonnet layout view. After topping up the oil, the check
per formed by the oil level indicator in
the instrument panel when the ignition
is switched on is not valid during the
30
minutes after topping up.
Engine oil change
In order to maintain the reliability of the engine
and emission control system, never use
additives in the engine oil.
Brake fluid level
The brake fluid level should be close
to the "MA X" mark. If it is not, check
the brake pad wear.
Changing the fl
uid
Refer to the manufacturer's service schedule
for details of the inter val for this operation.
Fluid specification
This fluid must conform to the manufacturer's
recommendations.
Coolant level
Check the coolant level regularly.
It is normal to top up the fluid
between two services.
To ensure that the reading is correct, your
vehicle must be parked on a
level sur face with
the engine cool.
The coolant level should be close to the "MA X"
mark but should never exceed it.
If the level is close to or below the "MIN" mark,
it is essential to top up.
A low coolant level presents a
risk of serious
damage to your engine.
When the engine is warm, the temperature of
the coolant is regulated by the fan.
