133) The "4LLc" range gives maximum
torque for low-speed driving on steep
slopes, as well as sandy, muddy, and other
difficult surfaces. On vehicles with
automatic transmission, do not exceed
speeds of approximately 70 km/h in "4LLc"
range.
134) Do not drive your vehicle in the
indicator
"4HLc" or "4LLc" position on dry paved
roads and highways. Doing so may result in
excessive tyre wear, increased fuel
consumption, and possible noise
generation. It may also increase the
differential oil temperature, which may
damage the drive system. Further, the drive
train will be subjected to excessive loading,
resulting in oil leakage, component seizure,
or other serious problems. On dry paved
roads and highways, drive the vehicle in
"2H" or "4H" only.
135) Do not operate the drive
mode-selector while the rear wheels of the
vehicle are slipping on snow or ice.
136) If a problem is detected in the transfer
system, a safety device will activate. The
front and rear wheel lamps will go out, the
centre differential lock lamp will blink rapidly
(twice per second), and transfer shifting will
become impossible fig. 276. Park your
vehicle in a safe place, turn off the engine
AHZ101128
for a few moments. Restart the engine. The
lamp should resume normal operation. If
the lamps continue to blink, have the
vehicle checked by a Fiat Dealership as
soon as possible.
