theall-wheel drivecannot be disengaged.
Function of theLOW RANGE gear reduction
The LOWRANGE gear reduction enables very
slowdriving in therespectivegears. If youengage
LOWRANGE, theengine'sperformancecharac‐
teristics and theautomatic transmission's shift‐
ing characteristicsare adjustedaccordingly.The
transmission ratio from theengine to thewheels
is around 40% lowerthan in theroad position.
The drivetorque is increased correspondingly.

NotesonDSR
If youfail to adaptyour driving styleoryou are
inattentive,DSR can neither reduce therisk of
accident nor override thelaws of physics. DSR
cannottakeroad, weather and trafficconditions
intoaccount. DSR is only an aid. Youare respon‐
sible forasafedistance to thevehicle in front, for
vehicle speed and forbraking in good time.
DSR supports youwhen drivingdownhill. DSR
