WARNING
When driving off-road, your body is subject to forces from all directions, due to the uneven
surface. You could be thrown from your seat,
for instance. There is a risk of injury.
Always wear a seat belt, even when driving off-
road. G
WARNING
If you drive over obstacles or in ruts, the steer- ing wheel may jerk out of your grip, causing
injury to your hands.
Always hold the steering wheel firmly with
both hands. When driving over obstacles, you must expect steering forces to increase
briefly and suddenly. G
WARNING
Flammable material such as leaves, grass or
twigs may ignite if they come into contact with hot parts of the exhaust system. There is a risk of fire.
When driving off road or on unpaved roads,
check the vehicle's underside regularly. In
particular, remove parts of plants or other
flammable materials which have become
trapped. In the case of damage, contact a
qualified specialist workshop.
! When driving off-road or on unpaved sur-
faces, check the underside of the vehicle
and the wheels and tires at regular inter-
vals. In particular, remove any trapped for- eign objects, e.g. stones and branches.
Such foreign objects may:
R damage the chassis, the fuel tank or the
brake system
R cause imbalances and thus vibrations
R be flung out when you continue driving
If there is any damage, inform a qualified
specialist workshop.
When driving off-road and on construction
sites, sand, mud and water mixed with oil, for
example, may get into the brakes. This may
lead to a reduction in braking performance or total brake failure, also as a result of
increased wear. The braking characteristics
will vary depending on the material that has
got into the system. Clean the brakes after
driving off-road. If you then notice reduced
braking performance or hear scraping noises,
have the brake system checked at a qualified specialist workshop. Adjust your driving style
to the changed braking characteristics.
Driving off-road or on construction sites
increases the possibility of vehicle damage
which may in turn lead to the failure of certain assemblies and systems. Adapt your driving
style to the off-road driving conditions. Drive
carefully. Have any vehicle damage rectified
at a qualified specialist workshop as soon as
possible.
When driving on rough terrain, do not shift the transmission into the neutral position. You
could lose control when attempting to brake
the vehicle with the service brake. If your
vehicle cannot manage an uphill slope, drive
back down the slope in reverse gear.
When loading your vehicle for driving off-road or on a construction site, keep the vehicle's
center of gravity as low as possible.
Checklist before driving off-road X
Check the fuel and DEF levels (Y page 181)
and top up (Y page 148).
X Engine: check the oil level (Y page 250)
and add oil (Y page 252).
Before driving up or down steep gradients,
fill the oil to the maximum level.
i If you drive up or down steep gradients,
the 00B2 symbol may appear in the display.
The engine operating safety is not put at
risk if you have filled the engine oil to the
maximum level before the journey.
X Vehicle tool kit: check that the jack is
working (Y page 274).
X Make sure that a lug wrench (Y page 274),
wooden underlay for the jack, a robust tow Driving tips

Useful information
This Operator's Manual describes all models
as well as standard and optional equipment of your vehicle that were available at the time of going to print. Country-specific variations are
possible. Note that your vehicle may not be
equipped with all of the described functions.
This also applies to systems and functions
relevant to safety.
Read the information on qualified specialist
workshops (Y page 25). Important safety notes
G
WARNING
If you are driving and reach through the steer- ing wheel to operate the adjustment knob,
you could lose control of the vehicle. There is
a risk of an accident and injury.
Only operate the adjustment knobs when the vehicle is stationary. Do not reach through the
steering wheel when driving. G
WARNING
If you operate information systems and com-
munication equipment integrated in the vehi- cle 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 equip-
ment when the vehicle is stationary. G
WARNING
If the instrument cluster has failed or mal-
functioned, 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 immedi-
ately. 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 display only shows
messages and warnings from certain sys-
tems. You should therefore make sure your
vehicle is operating safely at all times. If the
operating safety of your vehicle is impaired,
stop the vehicle as soon as possible, paying
attention to road and traffic conditions. Then consult a qualified specialist workshop. Instrument cluster
