Brake pads

Brake wear depends on the style
of driving, par ticularly in the case
of vehicles used in town, over shor t
distances. It may be necessary to
have the condition of the brakes checked, even
between vehicle services.
Unless there is a leak in the system, a drop in
the brake fluid level indicates that the brake
pads are worn. The gearbox does not require any
maintenance (no oil change).
Refer to the Warranty and Maintenance
Record for the details of the level
checking interval for this component.


Brake disc wear
Manual parking brake

If a loss of effectiveness of this
system is noticed, the parking brake

CITROËN or products of equivalent
quality and specification.
In order to optimise the operation
of units as impor tant as the braking
system, CITROËN selects and offers
very specific products.
To avoid damaging the electrical units,
the use of a high pressure washer
in the engine compar tment is strictly
prohibited
.
The gearbox does not require any
maintenance (no oil change).
Refer to the Warranty and Maintenance
Record for details of the level checking
interval for this component. For information on checking brake

217Practical information











Battery
Procedure for charging your battery when it is flat or for starting the engine using another battery.
The battery is located under the bonnet.
To gain access to it:


)
open the bonnet using the interior release
lever, then the exterior safety catch,

)
secure the bonnet stay,

)
lift the plastic cover on the (+) terminal.



Access to the battery



)
Connect the red cable to the positive
terminal (+) of the flat battery A
, then to the
positive terminal (+) of the slave battery B
.


Starting using another
battery

After refitting the battery by a
CITROËN dealer or a qualified
workshop, the Stop & Star t system
will only be active after a continuous
period of immobilisation of the vehicle,
a period which depends on the climatic
conditions and the state of charge of
the battery (up to about 8 hours).





The presence of this label, in particular
with the Stop & Star t system, indicates
the use of a 12 V lead-acid battery with
special technology and specification;
the involvement of a CITROËN dealer
or a qualified workshop is essential
when replacing or disconnecting the
battery.
Failure to obser ve this recommendation
may cause premature wear of
the battery.

)
Connect one end of the green or black
cable to the negative terminal (-) of the
slave battery B
.

)
Connect the other end of the green or black
cable to the remote negative terminal (-) of
your vehicle.

)
Star t the slave vehicle.

)
Operate the star ter of the broken down
vehicle and let the engine run.

)
Wait until the engine returns to idle and
disconnect the cables.



Charging the battery using
a battery charger
Batteries contain harmful substances such
as sulphuric acid and lead. They must be
disposed of in accordance with regulations
and must not, in any circumstances, be
discarded with household waste.
Take used remote control batteries and
vehicle batteries to a special collection
point.


)
Follow the instructions for use provided by
the manufacturer of the charger.
Do not disconnect the battery
to charge it.
Do not push the vehicle to star t the
engine if your vehicle is fitted with a
"SensoDrive" gearbox.

219Practical information








Energy economy mode
System which manages the period of use of cer tain 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, cour tesy
lamps, etc. for a maximum combined period of thirty minutes.
This period may be greatly reduced if
the battery is not fully charged.
A flat battery prevents the engine from
starting (refer to the corresponding
paragraph). If the telephone is being used at
the same time on the MyWay audio
navigation system, it will be interrupted
after 10 minutes.


Switching to economy mode

Once this period has elapsed, a message
appears on the multifunction screen indicating
that the vehicle has switched to economy mode
and the active functions are put on standby.

Exiting economy mode

These functions are reactivated automatically
the next time the vehicle is driven.


)
In order to resume the use of these
functions immediately, star t the engine and
let it run for a few minutes.
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 thir ty minutes.
