Troubleshooting Guide

NOTICE
If the vehicle has been driven at high load for a
long period, the engine can overheat when it is
switched off. In order to avoid damage to the en-
gine, allow the engine to run in neutral for ap-
proximately two minutes before switching it off.
After the engine is switched off, the radia-
tor fan in the engine compartment may run
on for some minutes, even if the ignition is
switched off or the vehicle key has been re-
moved. The radiator fan will switch itself off au-
tomatically.

mobiliser automatically when a valid vehicle is
located inside the vehicle

The electronic immobiliser is activated automati-
cally once the valid vehicle key is no longer loca-
ted inside the vehicle
