Selecting the switch-on time for the
auxiliary heating* This function is only available if the vehicle
has an auxiliary heating system.
The
Auxiliary heating function allows you
to select three switch-on times. You can set
the exact switch-on time using the other func-
tions in the Heatersubmenu.
You can switch off the auxiliary heating by
using the remote control or the auxiliary heat-
ing button on the centre console.
The auxiliary heating is switched off automat-
ically after 50 minutes. This time can be
changed. To do this, visit a qualified specialist
workshop, e.g. a Mercedes-Benz Service
Centre. G
Risk of poisoning
Exhaust fumes are produced when the aux-
iliary heating is in operation. Inhaling these
exhaust fumes can be poisonous. You
should therefore switch off the auxiliary heating in confined spaces without an
extraction system, e.g. a garage.
G
Risk of fire
When operating the auxiliary heating, parts
of the vehicle may become very hot, and
highly inflammable material such as fuels
could be ignited. Operating the auxiliary
heating is thus prohibited at filling stations
or when your vehicle is being refuelled. You
must therefore switch off the auxiliary heat-
ing at filling stations.
You can call up the Auxiliary heating.

occupants becoming trapped. Before acti-
vating the easy-entry/exit feature, make
sure that nobody can become trapped.

Risk of accident
Observe the legal requirements of the
country in which you are currently driving
regarding the use of mobile phones in the
vehicle.
If it is permitted to use mobile phones while
the vehicle is in motion, you should only use
them when the road and traffic conditions
allow. You may otherwise be distracted

Overview of off-road driving systems
The systems which are relevant for off-road
driving are explained on the following pages:
R 4MATIC (permanent four-wheel drive), for
optimum traction
R DSR (Downhill Speed Regulation), which
assists you when driving downhill
R Off-road drive program, which assists you
when driving off-road
R LOW RANGE* off-road gear for better trac-
tion off-road
R Differential locks for increased traction off-
road
You will find further information about driving
off-road in the "Operation" section
(Y page 235). 4MATIC (permanent four-wheel drive)
4MATIC ensures that all four wheels are per-
manently driven. Together with ESP ®
and
4ETS, it improves the traction of your vehicle
whenever a drive wheel spins due to insuffi-
cient grip. G
Risk of accident
4MATIC cannot reduce the risk of an acci-
dent if you drive too fast.
If a drive wheel spins due to insufficient
grip:
R Only depress the accelerator pedal as far
as necessary when pulling away.
R Accelerate less when driving.
R Adapt your driving style to suit road and
traffic conditions.
i In wintry driving conditions, the maximum
effect of 4MATIC can only be achieved if
you use winter tyres (M+S tyres), with snow
chains if necessary.
! When testing the parking brake, operate
the vehicle only briefly (for a maximum of
ten seconds) on a brake dynamometer.
When doing this, turn the key to position
0 or 1in the ignition. Failure to do this can Controls
