locks, vehicle steerability is severely
restricted.
For your own safety, the safety of others, and
in order to avoid damage to the vehicle, the
differential locks must not be engaged when
driving on a firm road surface. Keep in mind
that when driving on firm road surfaces, the
unimpeded function of the differential is
necessary and must never be locked on firm
road surfaces. Vehicle steerability may
otherwise be lost and you may no longer be
able to steer the vehicle. For this reason, the
differential locks must be engaged
exclusively during off-road driving, and only
when activating the other driving systems
(4ETS, ESP
®
and off-road gear LOW) is no
longer sufficient.

General notes
G
Warning!
Never drive on firm road surfaces with
differential locks engaged. Never drive on
narrow bends with front-axle differential locks
engaged. With differential locks engaged, the
vehicle's ability to steer is severely restricted
and the danger of accidents is therefore
higher.
Do not engage or disengage differential locks
while driving on a bend. The vehicle may
otherwise make a jerking movement. You
could thus lose control of the vehicle and
cause an accident.
If you select a differential lock, ABS, 4ETS,
ESP
®
and BAS will be deactivated.
