Mercedes-Benz GL-Class 2011 Owners Manual - Manual (Page 160)

Shift ranges
There are two shift ranges.
HIGH
RANGE
On-road position for all
normal driving situations
(LOW RANGE off-road gear
off).
LOW
RANGE
In comparison with the
HIGH RANGE on-road
position, the gear ratio
between the engine and
wheels is one-third. Drive
torque is thus
proportionately higher.
G Warning!
Always wait until the procedure of shifting
from HIGH RANGE to LOW RANGE – and from
LOW RANGE to HIGH RANGE – has been
entirely completed. During this procedure do
not turn off the engine or shift the automatic
transmission into another gear.
If you do not wait until the shifting procedure
has been entirely completed then it might not
be correctly performed. The transfer case
might be in neutral, thus interrupting the
transfer of power between the engine and the
drive axle.
The vehicle is then freely movable, even if a
gear has been selected, and could
unintentionally be set into motion –
particularly on up – or downhill grades. This
could lead to an accident and cause injury to
yourself and others.
Please observe related messages appearing
in the multifunction display.
