When failure to start is due to low battery voltage and not to problems in the electric system avoid
starting the vehicle by towing.
To prevent damage to the vehicle, it is important to ensure the tanks contain sufficient fuel during
start-up. Attempting to start the engine with insufficient fuel could cause serious damage to the
injection system.
Do not start the engine without having first permanently connected the battery.
If the batteries require charging, disconnect them from the vehicle circuit.
ABSOLUTELY avoid using a fast battery charger for emergency starting: due to the high voltages
applied, the electronic systems, and in particular the control units that manage the ignition and supply
functions, could get damaged.
Auxiliary method start-up must only be carried out using an external battery carriage, according to the following procedure:
- observe all current accident prevention precautions (including the use of gloves);
- use a battery trolley with specifications similar to those of the vehicle battery;
- using a suitable cable, connect the positive pole of the battery trolley to the positive pole of the CBA control unit fitted on the
positive pole of the vehicle battery (see Figure 5.33 paragraph 5.4.5);
- using a suitable cable, connect the negative clamp of the battery trolley to the ground of the vehicle with a flat battery;
- when starting the engine on vehicles with a manual gearbox: turn the key ON and wait for all the engine warning lights on the
instrument panel to go off. Start the vehicle engine. The starter motor must not be used for longer than 10 seconds. Do not
depress the accelerator pedal during start-up;
- when starting the engine on vehicles with an automatic gearbox: turn the key ON and press the brake pedal. Wait for all the
engine warning lights on the dashboard to go off and for a ”Gearbox OK” message to appear on the display. Start the vehicle
engine. The starter motor must not be used for longer than 10 seconds. Do not depress the accelerator pedal during start-up;
- wait for the vehicle engine to reach idling speed;
- do not activate the vehicle’s electric services, for example low-beam headlights, heater, both in order to allow the accumulation
of a sufficient amount of energy and to avoid any current peaks which could damage the electronic control units when the battery
trolley is disconnected;
- firstly disconnect the vehicle negative terminal and then the battery trolley negative terminal;
- first disconnect the CBA cable fitted to the vehicle battery positive terminal and then the battery trolley positive terminal;
- the battery must in any case by recharged subsequently by disconnecting form the circuit using the correct slow, low current
recharging procedure;
- do not use other devices (battery charger) to start the engine. If in doubt, contact the IVECO service network.

Any damage to electronic control units caused by failure to comply with procedure is not covered by
the warranty.
See Chapter 5.3 for precautions to be adopted for installed control units.
