warn you until at least 20 minutes after
your journey has begun. You then hear an
intermittent warning tone twice and the

Attention Assist: Take a Break!
message appears in the multifunction

If necessary, take a break.
X Press the aor% button to confirm

On long journeys, take regular breaks in good
time to allow yourself to rest properly. If you
do not take a break and ATTENTION ASSIST
still detects increasing lapses in
concentration, you will be warned again after
15 minutes at the earliest.
ATTENTION ASSIST is reset when you
continue your journey and starts assessing
your tiredness again if:
R you switch off the engine.
R you take off your seat belt and open the
driver's door, e.g. for a change of drivers or
to take a break. Night View Assist Plus
General notes In addition to the illumination provided by the
normal headlamps, Night View Assist Plus uses infrared light to illuminate the road.
Night View Assist Plus camera
:picks up
the infrared light and displays a monochrome
image in COMAND. The image displayed in
COMAND corresponds to a road lit up by high-
beam headlamps. This enables you to see the
road's course and any obstacles in good time.
If pedestrian recognition is activated,
pedestrians recognized by the system are
highlighted in the Night View Assist Plus
display.
Light from the headlamps of oncoming
vehicles does not affect the Night View Assist
Plus display in the multifunction display. This
is also the case if you cannot switch on the
high-beam headlamps due to oncoming
traffic.
i Infrared light is not visible to the human
eye and therefore does not glare. Night
View Assist Plus can therefore remain
switched on even if there is oncoming
traffic.
Important safety notes Night View Assist Plus is only an aid and is not
a substitute for attentive driving. Do not rely
on the Night View Assist Plus display. You are
responsible for the distance to the vehicle in
front, for vehicle speed and for braking in
good time. Drive carefully and always adapt
your driving style to suit the prevailing road
and traffic conditions.
The system may be impaired or may not
function if:
R
there is poor visibility, e.g. due to snow,
rain, fog or spray
R the windshield is dirty, fogged up or
covered, for instance by a sticker, in the
vicinity of the camera

Towing a trailer
When you attach a trailer, make sure you have
correctly established the electrical
connection. This can be accomplished by
checking the trailer lighting. On-road programs (vehicles with the
ON&OFFROAD package)
General notes The on-road programs assist you during on-
road driving and the off-road programs when
driving off-road (Y
page 258).
The following program messages remain in

displayed in status indicator =.
When DSR is activated, you can change the
set speed to a value between 1 mph and
11 mph (Canada: between 2 km/h and

Off-road programs (vehicles with the
ON&OFFROAD package) General notes
The off-road programs assist you in driving
off-road. The engine's performance
characteristics and the gearshifting
characteristics of the automatic transmission
are adapted for this purpose. ABS, ESP ®
and
4ETS programs especially adapted to off-road
driving are activated. An accelerator pedal
curve suitable for the terrain is selected, i.e.
the accelerator pedal must be depressed
further to accelerate.
Do not use the off-road programs on roads
that are snow-covered or icy or if you have
mounted snow chains on your vehicle.
For information on driving off-road, see
(Y page 197).

WARNING
If you operate information systems and
communication equipment integrated in the
vehicle while driving, you will be distracted
from traffic conditions. You could also lose
control of the vehicle. There is a risk of an
accident.
Only operate the equipment when the traffic
situation permits. If you are not sure that this
is possible, park the vehicle paying attention
to traffic conditions and operate the
equipment when the vehicle is stationary. G
WARNING
If the instrument cluster has failed or
malfunctioned, you may not recognize
function restrictions in systems relevant to
safety. The operating safety of your vehicle
may be impaired. There is a risk of an
accident.
Drive on carefully. Have the vehicle checked
at a qualified specialist workshop
immediately.
You must observe the legal requirements for
the country in which you are currently driving
when operating the on-board computer.
The on-board computer only shows messages
or warnings from certain systems in the multifunction display. You should therefore
make sure your vehicle is operating safely at
all times. Otherwise, a vehicle that is not
operating safely may cause an accident.
