BATTERY: troubleshooting (continued)
Starting the vehicle using the
battery from another vehicle
Proceed as follows when starting
your vehicle from another vehicle’s
battery:
Obtain suitable jump leads (with a
large cross section) from a
RENAULT Dealer or, if you already
have jump leads, ensure that they
are in perfect condition.
The two batteries must have an
identical voltage: 12 volts. The
battery supplying the current should
have a capacity (amp-hours, Ah)
which is at least the same as that of
the discharged battery.
Ensure that there is no risk of
contact between the two vehicles
(risk of short circuiting when the
positive terminals are connected)
and that the discharged battery is
properly connected. Switch off your
vehicle ignition.
Start the engine of the vehicle
supplying the current and run it at
an intermediate engine speed. Check that there is no contact
between cables
Aand Band that
cable A(+) is not touching any metal
parts on the vehicle supplying the
current.
Start the engine as you would
normally. As soon as it is running,
disconnect cables A and B in the
inverse order (4-3-2-1).
Secure the positive cable (+) Ato the
(+) terminal 1 of the discharged
battery, then to the (+) terminal2 of
the battery supplying the current.
Attach negative cable (–) B to (–)
terminal 3 of the battery supplying
the current and then to (–) terminal4
of the discharged battery.

succession once towing is finished
(risk of running down the battery).

respect the towing regulations
defined in the legislation of the
country concerned and, if your
vehicle is the towing vehicle, do not
exceed the towing weight of your
vehicle. Contact your RENAULT

pedals. The steering column
unlocks, the vehicle accessory
functions are supplied with power
and you can use the lights (stop
lights, directional indicator lights,
etc.): the vehicle must have its lights
on at night.
Do not remove the RENAULT card
from the reader at any point when
the vehicle is being towed.
Towing a vehicle with
automatic transmission: special
information
Engine switched off: The gearbox is
no longer lubricated. It is preferable
to tow this type of vehicle on a
trailer or tow it with the front
wheels off the ground.
Under exceptional circumstances ,
you may tow the vehicle with all
four wheels on the ground, only
going forward, with the gear lever in
the N position, and for a distance
not exceeding 30 miles (50 km).
If the lever is stuck at P,
even though you are
depressing the brake
pedal, the lever can be
released manually.
To do this, unclip the upper
section of the cover at the base of
the lever.
Press simultaneously on the mark
on the gaiter and the unlocking
button on the lever.
