Cable connection order:
1. Connect the red cable of the booster
(1) to the positive terminal (+) of the
discharged battery (at the metal elbow)
(2) fig. 287.

booster (3) to a fastening bracket on the
12V battery's negative (
–
) (4) or to the
vehicle grounding point (5) near the 12V
battery in the engine compartment.
Route the leads so that they cannot
catch on rotating parts in the engine
compartment.
To start the engine:
1. Start the engine of the vehicle
providing the jump.
2. After 5 minutes, start the other
engine. Start attempts should be made
for no longer than 15 seconds at an
interval of 1 minute.
3. Allow both engines to idle for approx.
3 minutes with the leads connected.
4. Switch on electrical consumers e.g.
headlights, heated rear window.
5. Reverse above sequence exactly when
removing leads.
WARNING
283) Be extremely careful when starting
with jump leads. Any deviation from the
following instructions can lead to injuries
or damage caused by battery explosion or
damage to the electrical systems of both
vehicles.
284)
Avoid contact of the battery fluid
with eyes, skin, fabrics and painted
surfaces. The fluid contains sulphuric
acid which can cause injuries and
damage in the event of direct contact.
285)
Do not get too close to the radiator
cooling fan: the electric fan may start;
danger of injury. Scarves, ties and other
loose clothing might be pulled by moving
parts.
286)
Remove any metal objects (e.g.
rings, watches, bracelets), that might
cause an accidental electrical contact and
cause serious injury.
287) Protect your eyes and face before
handling the battery. All operations on
the battery must be carried out in a well
ventilated area and away from naked
flames and sources of sparks, to avoid any
risk of explosion or fire. Wash your hands
afterwards.
288) Never try to charge a frozen battery -
risk of explosion! If the battery has frozen,
have it checked by a Jeep Dealership,
who will verify that the internal
components have not been damaged and
that the case has not cracked, which
could lead to a risk of leakage of toxic and
corrosive acid.
IMPORTANT
120)
Never jump start another vehicle
with an electric vehicle.
121) Never connect the negative jump
lead to the metal part of the electronic
control units or at the back of the
headlamps. Risk of destroying the
electronic control units and/or headlamps!
Connect to the remote earth point
provided for this purpose.
122) With Electric Drive Unit, never try to
start the engine by pushing the vehicle.
123) Never start the engine by connecting
a battery charger. Never use a 24 V or
higher battery booster. Check beforehand
that the backup battery has a nominal
voltage of 12 V and a capacity at least
equal to that of the discharged battery.
The two vehicles must not be in contact
with each other. Switch off all electricity-
consuming equipment on both vehicles
(audio system, wipers, lighting, etc.).
Make sure that the jump leads are well
away from the engine’s moving parts (fan,
belt, etc.). Do not disconnect the (+)
terminal while the engine is running.
124) Driving immediately without having
reached a sufficient level of charge may
affect some of the vehicle's functions
(e.g. Stop-Start).
