Observe the following rules when driving over
tree stumps, large stones and other obstacles: R
Select the Offroad drive program (vehicles
with Off-Road Engineering package)
( Y
page 237).R
Select the Offroad drive program (vehicles
without Off-Road Engineering package)
( Y
page 237).R
Select LOW RANGE offroad gear (vehicles
with Off-Road Engineering package)
( Y
page 239)R
Raise the vehicle level. R
Avoid high engine speeds. R
Shift to a lower gear using the left-hand steer-
ing wheel paddle shifter. R
Drive very slowly. R
Drive straight over the center of obstacles.
Traveling uphill
Approach/departure angle
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. R
Observe the rules on off-road driving. R
Do not drive at an angle on slopes, inclines or
gradients, but instead follow the direct line of
fall. R
When driving down an incline, make use of the
engine's braking effect. Observe the engine
speed; do not overrev the engine. R
Select the Offroad drive program (vehicles
with Off-Road Engineering package)
( Y
page 237).R
Select the Offroad drive program (vehicles
without Off-Road Engineering package)
( Y
page 237).R
Before driving on extreme uphill and downhill
gradients, select the LOW RANGE off-road
gear (vehicles with Off-Road Engineering
package) ( Y
page 239).R
Drive slowly. R
Avoid high engine speeds. Drive at appropri-
ate engine speeds (maximum 3,000 rpm). R
Use the left-hand steering wheel paddle
shifter to shift into a lower gear in good time
on long and steep downhill gradients. R
Check the brakes after prolonged off-road
driving.
Hill start assist will aid you when pulling away on
a hill. For further information about hill start
assist, see ( Y
page 149).
Do not switch to transmission position N when
driving off-road. If you try to brake the vehicle
using the service brake, you could lose control
of the vehicle. If the gradient is too steep for your
vehicle, drive back down in reverse gear.
Always observe the approach/departure angle
values ( Y
page 443).
Maximum gradient-climbing capability Always observe the maximum gradient climbing
ability values ( Y
page 444).
Hilltops When driving up an uphill gradient, slightly
reduce pressure on the accelerator immediately
before reaching the brow of the hill. Make use of
the vehicle's own impetus to travel over the
brow.
This style of driving prevents: R
the vehicle from lifting off the ground on the
brow of a hill R
the vehicle from traveling too quickly down
the other side
Driving downhill R
Drive slowly. R
Do not drive at an angle down steep inclines.
Steer into the line of fall and drive with the
front wheels aligned straight. Otherwise, the
vehicle could slip sideways, tip and rollover. R
Shift to a lower gear using the left-hand pad-
dle shifter before tackling steep downhill gra-
dients. R
Activate DSR. If this is not sufficient, brake
gently. When doing so, make sure that the
vehicle is facing in the direction of the line of
fall. R
Check that the brakes are working normally
after a long downhill stretch.190

ings (left and right), and only on the vehicle in
front if lane markings are missing.
Steering Assist and Stop&Go Pilot do not pro-
vide any support if these conditions do not exist.
DISTRONIC PLUS must be active in order for the
function to be available.
Important safety notes If you fail to adapt your driving style, DISTRONIC
PLUS with Steering Assist and Stop&Go Pilot
can neither reduce the risk of an accident nor
override the laws of physics. It cannot take
account of road, weather and traffic conditions.
DISTRONIC PLUS with Steering Assist and
Stop&Go Pilot is only an aid. You are responsible
for the distance to the vehicle in front, for vehi-
cle speed, for braking in good time and for stay-
ing in your lane.
DISTRONIC PLUS with Steering Assist and
Stop&Go Pilot does not detect road and traffic
conditions. If you are following a vehicle which is
driving towards the edge of the road, your vehi-
cle could come into contact with the curb or
other road boundaries. Be particularly aware of
other road users, e.g. cyclists, that are directly
next to your vehicle.
Obstacles such as traffic pylons on the lane or
projecting out into the lane are not detected.
An inappropriate steering intervention, e.g. after
intentionally driving over a lane marking, can be
corrected at any time if you steer slightly in the
opposite direction.
DISTRONIC PLUS with Steering Assist and
Stop&Go Pilot cannot continuously keep your
vehicle in lane. In some cases, the steering
intervention is not sufficient to bring the vehicle
back to the lane. In such cases, you must steer
the vehicle yourself to ensure that it does not
leave the lane.
The support provided by the system can be
impaired if: R
there is poor visibility, e.g. due to insufficient
illumination of the road, or due to snow, rain,
fog or spray R
there is glare, e.g. from oncoming traffic, the
sun or reflections (e.g. when the road surface
is wet) R
the windshield is dirty, fogged up, damaged or
covered, for instance by a sticker, in the vicin-
ity of the camera R
there are no, several or unclear lane markings
for a lane, e.g. in areas with road construction
work R
the lane markings are worn away, dark or cov-
ered up, e.g. by dirt or snow R
the distance to the vehicle in front is too small
and the lane markings thus cannot be detec-
ted R
the lane markings change quickly, e.g. lanes
branch off, cross one another or merge R
the road is narrow and winding R
there are strong shadows cast on the road
The system is switched to passive and no longer
assists you by performing steering interventions
if: R
you actively change lane R
you switch on the turn signal R
take your hands off the steering wheel or do
not steer for a prolonged period of time
i Steering Assist and Stop&Go Pilot are acti-
vated again automatically after a lane change
is completed.
Steering Assist and Stop&Go Pilot do not pro-
vide any support: R
on very sharp corners R
when a loss of tire pressure or a defective tire
has been detected and displayed
Pay attention also to the important safety notes
for DISTRONIC PLUS ( Y
page 193).
The steering interventions are carried out wit h a
limited steering moment. The system requires
the driver to keep his hands on the steering
wheel and to steer himself.
If you do not steer yourself or if you take your
hands off the steering wheel for a prolonged
period of time, the system will first alert you with
a visual warning. A steering wheel symbol
appears in the multifunction display. If you have
still not started to steer and have not taken hold
of the steering wheel after five seconds at the
latest, a warning tone also sounds to remind you
to take control of the vehicle. Steering Assist
and Stop&Go Pilot are switched to passive.
DISTRONIC PLUS remains active.
