CAUTION

If LHS had previously been used in MANUAL mode and not completely

stowed in AUTO mode, the hook arm cylinders must be completely

extended or the LHS must be completely stowed using AUTO mode

before the flatrack can be loaded. Failure to comply may result in damage

to the vehicle and flatrack.

804 kg) payload, of the load handling system (LHS) could cause

overheating, and system failure to pick up the load. Allow the hydraulic

reservoir is cool. The hydraulic reservoir is cool when you can hold your

hand on the reservoir for more than 10 seconds.
