LOW RANGE transmission ratio

General notes
The LOW RANGE transmission ratio assists
you when driving on difficult terrain. If you
engage LOW RANGE, the engine's perform-
ance characteristics and the automatic trans-
mission's shifting characteristics are adjus-
ted accordingly. The transmission ratio from
the engine to the wheels is around 40% lower
than in the on-road position. This increases
the drive torque.
Conditions for engaging/disengaging
LOW RANGE can only be engaged or disen-
gaged if:
the engine is running
R
the vehicle is stationary
R
the brake pedal is depressed
R
the selector lever of the automatic trans-
R
mission is in position P or N
all-wheel drive is engaged
