Battery – Initialisation
When removing or disconnecting the battery, check that the battery is working correctly by performing a number of
initialisations on different vehicle functions. These initialisations do not require a tool of any kind.
Anti-theft code:
–Entering a 4-digit radio or radionavigation code (see 86A, Radio, Radio: Protection code). Setting the time on
the radio or the radio navigation system:
–To set the radio navigation system time, enter the four digit code. Insert the navigation CD-ROM then drive the
vehicle to pick up the satellite signals. It is now possible to set the time (see 86A, Radio, Radio: Setting the
time).
Initialisation of the window winders:
–Check that the electric windows are still initialised. The windows should open and close when the switch is
pressed. If this does not happen, re-initialise (see 87D, Electric windows - sunroof, Electric windows:
Initialisation).
Initialising the sunroof:
–Check that the sunroof is still initialised. The sunroof should open or close to the requested position without
stopping. If this does not happen, re-initialise (see 87D, Electric windows - Sunroof, Electric sunroof:
Initialisation).
Initialising the electric power assisted steering:
–In order that the electric power-assisted steering recognises the "steering wheel angle" signal, move the steering
wheel from lock to lock with the engine running (see 36B, Power-assisted steering, Fault finding -
Replacement of components).
Initialising the computers:
– The other computers are automatically initialised when the vehicle is being driven. Drive the vehicle for at least
1 minute at a speed greater than 18 mph (30 km/h) so that the tyre pressures are displayed again.

Battery – Specifications
Battery specifications:
Always replace a battery with one that has the same electrical and dimensional specifications.
Visual inspection of the battery
Make sure there are no cracks or breakages, traces of acid, or creepage (sulphation) on the terminals. If any of the
above are present, replace the battery and clean the surrounding area.
Check that the degassing pipe is properly connected to the battery vent
Check that the degassing pipe (4) is correctly positioned.1Hydrometer (magic eye)

Battery – Advice
IMPORTANT
•All vehicles are equipped with low water consumption batteries. Opening the battery and topping up the
electrolyte are FORBIDDEN.
•Batteries contain sulphuric acid, which is a hazardous chemical.
•Battery charging produces hydrogen and oxygen, which are very flammable gases and thus there is a risk of
explosion.
•Any batteries with filling plugs must not be opened under any circumstances but replaced immediately with
Renault approved batteries.
Battery recharging:
When parked, vehicles consume power through their permanent consumers and through any accessories fitted as
After-Sales options. To keep battery discharging to a minimum, limit the number of times the vehicle is started, periods
with the ignition on, doors open, etc., as much as possible.
A discharged battery must be recharged using a Renault-approved battery charger (see Technical Note 6512A)
Battery storage:
Even when stored off the vehicle, a battery gradually discharges, and more rapidly if the ambient temperature is high.
In order that a battery remains operational for a long time, it must be stored at a temperature of around
15˚C and in a dry place. To retain a good level of charge, it is recommended that a battery is completely recharged
after it has been stored for 3 months.
A new battery that has been stored for more than one year must not be fitted to a vehicle.IMPORTANT
•Simultaneous recharging of several batteries in series or in parallel is forbidden.
•A battery charger used on a battery connected to a vehicle can irreparably damage the vehicle computers due
to the high voltages created when charging.
•The location of the charger must take this into account (ventilation).
•A battery charger or a booster not approved by Renault can damage the electrical components.

Test procedure using the MIDTRONICS tool
Test conditions
The measurement must be taken when the vehicle is stationary and the ignition is off.
If the engine has been run in the last hour, switch the battery status to test and carry out the following operations:
•engine switched off,
•switch on the main beam headlights for 2 minutes,
•switch off the main beam headlights,
•wait for 2 minutes,
•switch off the ignition.
Equipment to be used:
•Tester approved by the Service Department: MIDTRONICS MICRO R330.
•Tool available as part no.: Elé. 1593.
•Equipment available in France from the Parts Department.
•Tool available in 6 languages.
For other countries, consult your contact in your country. Special tooling required

WARNING
Failure to observe the procedure or poorly maintained equipment may result in incorrect measurements, which
could be:
–detrimental to the customer (the battery is not sound),
–detrimental to RENAULT (unnecessary replacement of a sound or rechargeable battery),
–detrimental to the dealership (if the battery is tested as sound or rechargeable for a part return under
warranty, the warranty reimbursement request will be cancelled).
