Transfer case
The vehicle has permanent 4-wheel drive
(4MATIC). Power is always transmitted to
both axles.
!
Performance tests may only be carried
out on a 2-axle dynamometer. The brake
system or transfer case could otherwise be
damaged. Contact an authorized
Mercedes-Benz Center for a performance
test. Mercedes-Benz recommends that you
use an authorized Mercedes-Benz Center
for this purpose.
!
If the parking brake is being tested on a
brake dynamometer, the ignition must be
switched off (SmartKey or Start/Stop
button in position 0 or 1), as ESP
®
will
otherwise automatically intervene. The test
must last a maximum of 10 seconds. The
brake system could otherwise be damaged.
LOW RANGE off-road gear
The LOW RANGE off-road gear is only
available in vehicles with the Off-Road Pro
Engineering package.
Use the LOW RANGE off-road gear:
R
when driving off-road
R
when fording
R
when towing on uphill or downhill gradients
When LOW RANGE is engaged, the engine’s
performance characteristics and the
gearshifting characteristics of the automatic
transmission are adapted for this purpose. In
addition, ABS, ESP
®
and 4ETS specially
adapted to off-road driving will be activated.
