MANUAL OPERATION:
– The parking brake is engaged by pulling on the control lever (normal braking immobilises the vehicle).
– Over-application can be obtained by pulling and holding the lever for 5 seconds (maximum application for steep
hills or when the vehicle has reached its maximum permissible all-up weight).
– When the parking brake is applied, the computer super-applies if the force applied to the rear brake callipers is
insufficient (pads cooling) or if the computer detects slight vehicle movement. This detection is limited to
24 hours.
– The parking brake is released when the control lever is applied fully and the release switch is pressed.
ASSISTED OPERATION:
The electronic parking brake enables assisted application and release of the brake:
●Applying the brake: When the engine is switched off, the parking brake is applied when the driver presses the
start button
●Releasing: The brake releases when the drive wheels reach the torque required to move the vehicle
(Note:with automatic transmission, the driver's door must be closed).
Restrictions on assisted brake release in automatic transmissions:
Assisted release is not allowed in the following cases:
– Opening the driver's door followed by engaging a gear (gear lever in position D).
– Engaging a gear (gear lever in position D) followed by opening the driver's door. Note:
When the parking brake is applied, the red light on the instrument panel (brake pads) and indicator light on the
lever are lit.
Below 6 mph (10 km/h) pulling the lever applies the rear brakes. Above 6 mph (10 km/h) pulling the lever
provides dynamic emergency braking without locking the rear wheels (statutory deceleration of 1.5 m/s
2).
The electronic parking brake can only be released when the steering column is unlocked (forced + after ignition
feed, see Introduction).
Note: In this case, the instrument panel displays the message Lever in P or N and the buzzer on the instrument
panel sounds.
Note: In this case, release is authorised for 5 s after the driver's door has been opened (e.g. for a manoeuvre).
After 5 seconds release is prevented.
Note:
Assisted braking and release only occurs if the computer has been configured.
For details on how these configurations function, see Configuration and programming.

WARNING LIGHT MANAGEMENT
Indications of a level 1 fault:
–Check Parking Brake message on the instrument panel display.
–orange warning light (P in a triangle) on the instrument panel comes on.
–SERVICE warning light comes on.
Indications of a level 2 fault:
–Parking brake defective message on the instrument panel display.
–1-second audible warning (from the instrument panel),
–orange warning light (P in a triangle) on the instrument panel comes on.
–SERVICE warning light comes on,
–Red indicator light (brake pad light) on the instrument panel comes on.
– parking brake control lever indicator light flashes.
Warning occurs:
– when the door is opened and a gear is engaged on an automatic transmission,
– when the vehicle is moving, despite the parking brake being applied,
– when the door is opened, with the engine running and the parking brake released,
– when the door is opened, with the engine stopped and the parking brake released, Note:
When the lever warning light stops flashing, the instrument panel message disappears. If the system has a level 2
fault, whenever the lever is used, the indicator light on the lever starts flashing again and the fault message
reappears.

ELECTRONIC PARKING BRAKE
Fault finding – Replacement of components
A/ PROCEDURE FOR REPLACING AN ELECTRONIC PARKING BRAKE COMPUTER
●For the description of the mechanical operations for replacing the control unit (computer) and brake cables (see
MR405 (Espace IV) or MR395 (Laguna II) or MR370 (Scénic), Mechanical, 37B, Electronic parking brake,
Control unit: Removal - Refitting and 37A, Mechanical component controls, Parking brake cables:
Removal - Refitting or MR353 (Vel Satis), Mechanical, 37B, Automatic parking brake, Control unit and
brake cables).
●The parking brake cables must always be replaced when the computer is replaced.
●In the same way, the computer must be replaced when the parking brake cables are changed.
●Conversely, the lever and the parking brake are independent of one another.
●Lever replacement must be carried out with + after ignition feed switched off and the parking brake released,
otherwise faults may occur.
●The clutch sensor must be replaced with + after ignition feed switched on to avoid a fault being provoked.
BEFORE REPLACING THE PARKING BRAKE COMPUTER:
If the vehicle has a manual gearbox, recover the clutch data from the memory of the old computer so that it can be
entered into the new computer (see section C).
Operations to perform before replacement:
– Switch on the ignition, connect the diagnostic tool and establish dialogue with the computer (parking
brake field).
– before replacing the computer, check that it is actually causing the fault by reading the faults and apply
the fault finding procedure concerned.
Steps to follow after replacement:
– with the ignition switched off, replace the electronic parking brake computer (with the approval of
Te c h l i n e ) .
– switch on the ignition, connect the diagnostic tool and establish dialogue with the computer (parking
brake field),
– apply the procedure described in section B: NEW COMPUTER CALIBRATION AND INITIALISATION,
– release the parking brake lever to reset the cables.
– check parking brake operation by testing the braking, maximum braking, and release,
– read the faults to clear any stored faults and check that replacing the computer has enabled the fault on
the vehicle to be rectified (no faults present).
– read the configuration (repair mode menu) to check that the parking brake computer configuration has
been correctly configured.
– depending on the configuration chosen, check the assisted braking and release. Note:
An electronic parking brake computer should be replaced only when requested by the Techline (fill out the fault
finding log).
Note:
With an automatic transmission, no data recovery is required (the computer can be replaced without applying
sections C and D).
Important:
Do not clear the faults from the computer before replacing it.
IMPORTANT: It is strictly forbidden to drive a vehicle with an electronic parking brake computer unless it is in
customer mode.

C/ CLUTCH DATA BACKUP (for vehicles with a manual gearbox)
Purpose of the procedure:
The data saved relates to the clutch engagement point. This is important when the clutch wears, because this data
enables the parking brake to release electronically when the clutch enables the vehicle to move off.
If this data cannot be retrieved from the old computer (impossible to establish dialogue with the diagnostic tool) or a
new clutch has been fitted, the new computer has to be programmed with the clutch engagement point: drive the
vehicle, downshifting at least 30 times (from 5
th to 4th gear) before returning the vehicle to the customer.
If the clutch data is not recorded in the new computer, the operation of the assisted brake on steep slopes will be
impaired when first used.
Perform the following operations:
– establish dialogue with the computer,
– select the repair mode menu on the diagnostic tool.
– open the programming menu,
– run function SC005 Backup clutch pedal programming (the data is written to a file that is automatically
selected when the new computer is programmed).
– replace the electronic parking brake computer (see MR405 (Espace IV) or MR395 (Laguna II) or
MR370 (Scénic), Mechanical, 37B, Electronic parking brake, Control unit: Removal - Refitting or
MR353 (Vel Satis), Mechanical, 37B, Automatic parking brake, Control unit),
– follow the procedures described in sections A and B.
D/ CLUTCH DATA ENTRY (for vehicles with automatic transmission)
The initialisation must be carried out (sections A and B).
Perform the following operations:
– establish dialogue with the computer,
– select the repair mode menu on the diagnostic tool.
– open the programming menu,
– run function: SC006 Enter clutch pedal programming.
– check that the electronic parking brake is operating correctly, including the assisted release function. IMPORTANT:
Do not apply this procedure in the event of a clutch fault.
Note:
– For vehicles fitted with an automatic gearbox, command SC005 Save clutch pedal programming is
unavailable.
– Command SC006 Enter clutch pedal programming, is also unavailable if command SC005 has not already
been activated.
