Drive
The automatic transmission
changes gear itself. All forward
gears are available.
You can influence the gearshifts
and shift gears yourself or limit the
shift range. Changing gear
The 5-speed automatic transmission adapts
to your individual driving style by contin-
uously adjusting its shift points. These shift
point adjustments take into account the cur-
rent operating and driving conditions. If the
operating or driving conditions change, the
automatic transmission reacts by adjusting
the gearshift program.
When the selector lever is in position D, the
automatic transmission selects the individual
gears automatically. This depends on:
R any restriction in the shift range
(Y page 146)
R the position of the accelerator pedal
R the road speed Touchshift
When the selector lever is in position D, you
can perform gearshifts yourself.
X To shift down: press the selector lever to
the left towards D–.
The automatic transmission shifts to the
next gear down, depending on the gear cur-
rently engaged. The shift range is also
restricted.
i The automatic transmission does not shift
down if you press the selector lever
towards D–while traveling at too high a
speed. This protects the engine from over-
revving.
X To shift up: briefly press the selector lever
to the right towards D+.
The automatic transmission shifts to the
next gear up, depending on the current

Important safety notes
G
WARNING
Flammable material such as leaves, grass or
twigs may ignite if they come into contact with
hot parts of the exhaust system or exhaust
gas flow. There is a risk of fire.
Park the vehicle so that no flammable mate-
rials come into contact with parts of the vehi-
cle which are hot. Take particular care not to
park on dry grassland or harvested grain
fields. G
WARNING
If you switch off the ignition while driving,
safety-relevant functions are only available
with limitations, or not at all. This could affect,
for example, the power steering and the brake
boosting effect. You will require considerably
more effort to steer and brake. There is a risk
of an accident.

General notes G
WARNING
If you shift down on a slippery road surface in
an attempt to increase the engine's braking
effect, the drive wheels could lose their grip.
There is an increased danger of skidding and
accidents.
Do not shift down for additional engine brak-
ing on a slippery road surface. G
DANGER
If the exhaust pipe is blocked or adequate
ventilation is not possible, poisonous gases
such as carbon monoxide (CO) may enter the
vehicle. This is the case, e.g. if the vehicle
becomes trapped in snow. There is a risk of
fatal injury.
If you leave the engine or the auxiliary heating
running, make sure the exhaust pipe and area
around the vehicle are clear of snow. To
ensure an adequate supply of fresh air, open
a window on the side of the vehicle that is not
facing into the wind.
Have your vehicle winterproofed at a qualified
specialist workshop in good time at the onset
of winter.
i Do not cover the radiator, e.g. with a win-
ter cover. The measurements of the on-
board diagnostic system may otherwise
return inaccurate values. Some of these values are legally prescribed and must
therefore always be exact.
Observe the notes in the "Winter operation"
section (Y page 288).
Driving with summer tires Observe the notes in the "Winter operation"
section (Y

Slippery road surfaces G
WARNING
If you shift down on a slippery road surface in
an attempt to increase the engine's braking
effect, the drive wheels could lose their grip.
There is an increased danger of skidding and
accidents.
Do not shift down for additional engine brak-
ing on a slippery road surface. G
WARNING
The outside temperature indicator is not
designed to serve as an ice-warning device
and is therefore unsuitable for that purpose.
Indicated temperatures just above the freez-
ing point do not guarantee that the road sur-
face is free of ice. The road may still be icy,
especially in wooded areas or on bridges.
! Vehicles with automatic transmission
may roll only briefly in the neutral position
N. Prolonged rolling of the wheels, e.g.
when being towed, will result in transmis-
sion damage.
If the vehicle threatens to skid or cannot be
stopped when moving at low speed:
X Shift the transmission to neutral position
N.
X Try to maintain control of the vehicle using
corrective steering.
Drive particularly carefully on slippery roads.
Avoid sudden acceleration, steering and
braking maneuvers. Do not use cruise
control. 158

tires and snow chains in the "Wheels and
tires" section (Y page 288). Driving off-road
Important safety notes G
WARNING
If you drive on a steep incline at an angle or
turn when driving on an incline, the vehicle
could slip sideways, tip and rollover. There is
a risk of an accident.
Always drive on a steep incline in the line of
fall (straight up or down) and do not turn the
vehicle. G
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.
! If there are steep gradients while driving
off-road, a sufficient filling level in the DEF
tank must be ensured. Make sure for this
reason that there is a minimum fill level of
ten liters before driving off-road.
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. Driving tips
