CHECKING LEVELS
Check all of these levels regularly and
top them up if necessary, unless other-
wise indicated.
If a level drops signifi cantly, have the
corresponding system checked by a
PEUGEOT dealer. Brake fluid level
In addition, as the cooling system is
pressurised, wait at least one hour after
switching off the engine before carrying
out any work.
To avoid any risk of scalding, unscrew
the cap by two turns to allow the pres-
sure to drop. When the pressure has
dropped, remove the cap and top up
the level.
Oil level The reading will only be correct
if the vehicle is on level ground
and the engine has been off for
more than 15 minutes.
The check is carried out either when the
ignition is switched on using the oil level
indicator on the instrument panel, or us-
ing the dipstick. The brake fl uid level should be
close to the "MAX" mark. If it is
not, check the brake pad wear.
Changing the fl uid
Refer to the Warranty and Maintenance
Record for details of the interval for this
operation.
Power steering fluid level The power steering fl uid level
should be close to the "MAX"
mark. Unscrew the cap, with
the engine cold, to check the
level. Screenwash and headlamp
wash fluid
In the case of vehicles fi tted with
headlamp washers, the minimum
level of this fl uid is indicated by an
audible signal and a message on
the multifunction screen.
Top up the level when you stop the vehicle. Engine oil change
Refer to the Warranty and Maintenance
Record for details of the interval for this
operation.
In order to maintain the reliability of the
engine and emission control system,
the use of additives in the engine oil is
prohibited.
Oil specifi cation
The oil must correspond to your engine
and conform to the manufacturer's recom-
mendations. Fluid specifi cation
The brake fl uid must conform to the
manufacturer's recommendations and
fulfi l the DOT4 standards.
Changing the coolant
The coolant does not have to be
changed.
Fluid specifi cation
For optimum cleaning and to avoid
freezing, this fl uid must not be topped
up with or replaced with water.
Coolant level
The coolant level should be
close to the "MAX" mark but
should never exceed it.
When the engine is warm, the tempera-
ture of the coolant is regulated by the fan.
This can operate with the ignition off.

On vehicles which are fi tted with a
particle emission fi lter, the fan may
operate after the vehicle has been
switched off, even if the engine is
cold. Fluid specifi cation
The coolant must conform to the manu-
facturer's recommendations.
When working under the bon-
net, take care, as certain areas
of the engine may be extremely
hot (risk of burns).

Let the engine run for the
duration specifi ed to ensure
that the battery charge is suf-
fi cient.
Do not repeatedly and continuously
restart the engine in order to charge
the battery.
A fl at battery prevents the engine
from starting (refer to the "Battery"
paragraph).
If the telephone is being used
at this time:
- it will be maintained for 5 minutes with the hands-free kit of your
Peuget Connect Sound or Peugeot
Connect Navigation,
- it will still be possible to fi nish the call with the Peugeot Connect
Media. Exiting economy mode
These functions are reactivated auto-
matically next time the vehicle is driven.

 In order to resume the use of these
functions immediately, start the en-
gine and let it run:
- for less than ten minutes, to use the equipment for approximately
fi ve minutes,
- for more than ten minutes, to use the equipment for up to approxi-
mately thirty minutes.
LOAD REDUCTION MODE
System which manages the use of cer-
tain functions according to the level of
charge remaining in the battery.
When the vehicle is being driven, the load
reduction function temporarily deactivates
certain functions, such as the air condition-
ing, the heated rear screen...
The deactivated functions are reactivat-
ed automatically as soon as conditions
permit.
ENERGY ECONOMY MODE
System which manages the duration of
use of certain functions to conserve a
suffi cient level of charge in the battery.
After the engine has stopped, you can
still use functions such as the audio and
telematics system, windscreen wip-
ers, dipped beam headlamps, courtesy
lamps, etc. for a maximum combined
duration of thirty minutes.

message appears on the multi-function
screen indicating that the vehicle has
switched to economy mode and the ac-
tive functions are put on standby.

PRACTICAL INFORMATION
191
TOWING A TRAILER,A CARAVAN, ETC.
Your vehicle is primarily designed for
transporting people and luggage, but it
may also be used for towing a trailer. Driving advice
The maximum towing load on a long
slope depends on the gradient and the
ambient temperature.
In all cases, pay attention to the coolant
temperature.
Side wind

 Take into account the increased
sensitivity to side 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.

 To lower the engine speed, reduce
your speed. Braking
Towing a trailer increases the braking
distance.
Tyres

 Check the tyre pressures of the tow-
ing vehicle and of the trailer, observ-
ing the recommended pressures.
Lighting

 Check the electrical lighting and
signalling on the trailer.
The rear parking sensors will
be deactivated automatically if
a genuine PEUGEOT towbar
is used.
 If the warning lamp and the

STOP warning lamp come
on, stop the vehicle and
switch off the engine as
soon as possible.
Towbar suitable for the attachment of a
trailer or caravan with additional lighting
and signalling.
Distribution of loads

 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. Above
1 000 metres, the maximum towing load
must be reduced by 10 % and so on for
every 1 000 metres of altitude.
Refer to the "Technical Data" section for
details of the weights and towing loads
which apply to your vehicle.
Driving with a trailer subjects the towing
vehicle to more signifi cant stress and its
driver must be particularly careful.
We recommend the use of
genuine PEUGEOT towbars
and their harnesses that have
been tested and approved from the
design stage of your vehicle, and that
the fi tting of the towbar is entrusted
to a PEUGEOT dealer.
If the trailer is not fi tted by a PEUGEOT
dealer, it is imperative that it is fi tted
using the electrical pre-equipment in-
stalled at the rear of the vehicle, in
accordance with the manufacturer's
instructions.
