GENERAL
OPERATIONS TO BE CARRIED OUT BEFORE AND AFTER A DISCONNECTION OF THE BATTERY
Before reconnecting the battery
.
Doors and tailgate.
WARNING: Before disconnecting the battery, partially open the door
windows.
Automatic gearbox.
If the vehicle has to remain stationary: Pplace the gear lever in the parking
position "P".
If the vehicle has to be moved: Place the gear lever in the neutral position
"N".
Electric parking brake.
If the vehicle has to remain stationary: Activate the electric parking brake.
If the vehicle has to be moved: Deactivate the electric parking brake.
Features of the vehicle's electrical supply.
When the boot is closed and the battery is disconnected, it is possible to
supply the vehicle by connecting another battery or a 12Vexterior supply.
Operations to be performed:
- Link the earth of the exterior supply to the vehicle earth.
- Link the 12Vof the exterior supply to the positive terminal of the battery +
unit, in the front left hand side of the engine compartment.
After reconnecting the battery
.
Antiscanning function.
It is necessary to wait 1 minuteafter reconnecting the battery in order to be
able to restart the vehicle.
Electric windows.
It may be necessary to re-initialise the sequential and anti-pinch functions.NOTE:If the window is open at the time the battery is reconnected, action
the window switch several times to close it, then re-initialise.
Open the window fully.
Action and release the window switch until the window is completely closed.
NOTE:This operation has to be carried out on each electric window.
Sun roof.
The anti-pinch function has to be re-initialised.
Place the sun roof switch in the maximum tilt position.
Keep the sun roof switch pressed until the sun roof ceases its movement.
Release the sun roof switch.
Press the sun roof switch within 5 seconds.
Keep the sun roof switch pressed until the end of the sun roof opening
sequence.
Multifunction screen.
It is necessary to adjust the date, time and outside temperature.
Adjust the display language of the multifunction screen if necessary.
NOTE:The default display language of the multifunction screen is French.
Reconfigure the personalisation menu of the multifunction screen.
Radio.
Reprogramme the radio stations.
Telematic control unit (RT3 radiotelephone).
Reprogramme the radio stations.
Navigation.
Warning: the vehicle has to be out in the open (when you switch on
the ignition, the navigation ECU searches for satellites).
Reprogramme the customer parameters.

CHECKING THE VALVE TIMING
Engine: ES9A
B1EP15UDB1EP08TC
Checking the valve timing (continued).
Peg the crankshaft, using tool [1].
Check that the tool [2]engages without effort in the cylinder heads at the camshaft pulleys.
Remove the tools [1]and [2].
Refit:
- The lower timing cover (13).
- The upper timing covers (9)and (10).
- The crankshaft pulley (12).
- The roller/dynamic tensioner assembly (11).
- The power steering pulley.
Complete the refitting of components.
Initialise the ignition injection ECU.

CHECKING AND SETTING THE VALVE TIMING
Engine: ES9A
Tensioning the timing belt.
Act on the tensioner roller (24)so as to align the marks «c»and «d», without detensioning the timing belt
(failing this, restart the operation of adjusting the belt tension).
Hold the tensioner roller (24).
Tighten the nut (23), tighten to 1 ± 0,1 m.daN.
Check the position of the tensioner roller (the alignment of the marks «c»and «d»should be correct).
Remove the tools [1], [2]and [4].
Turn the crankshaft 2 rotationsclockwise.
IMPERATIVE: Never turn it back.
Peg the crankshaft, using tool [2].
Check the position of the tensioner roller (the alignment of the marks «c»and «d»should be correct).
Peg the camshaft pulleys, using tool [1].
If the peg [1]goes in: Loosen the exhaust camshaft pulley screws by 45°.
If the peg [1]does not go in: Slacken the exhaust camshaft pulley screws by 45°.
Bring the exhaust camshaft hub to the pegging position (5), using tool [5].
WARNING: Check that the exhaust camshaft pulleys are not at the end of slots. Otherwise, restart
the operation to position the timing belt.
Tighten the exhaust camshaft pulley screws to 1 ± 0,1 m.daN.
Remove tools[1] and [2].
Complete the refitting.
Initialise the injection ECU (see corresponding operation).
