Where ruts are too deep, drive with the
wheels of one side on the center grassy area,
if possible.
Driving over obstacles
! Obstacles could damage the floor of the
vehicle or components of the chassis. Ask
passengers for guidance when driving over
large obstacles. The passenger should always
keep a safe distance from the vehicle when
doing so in order to avoid injury as a result of
unexpected vehicle movements. After driving
off-road or over obstacles, check the vehicle
for possible damage, especially to the under-
body and the components of the chassis.164

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

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 136).
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 383).
Maximum gradient-climbing capability Always observe the maximum gradient climbing
ability values ( Y
page 383).
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 tips 165

Driving systems
Driving and parking
In such cases, Distance Pilot DISTRONIC may: R
give an unnecessary warning and then
brake the vehicle R
neither give a warning nor intervene R
accelerate or brake unexpectedly
There is a risk of an accident.
Continue to drive carefully and be ready to
brake, especially if Distance Pilot DISTRONIC
warns you.
G WARNING
Distance Pilot DISTRONIC brakes your vehicle
with up to 50% of the maximum possible
deceleration. If this deceleration is not suffi-
cient, Distance Pilot DISTRONIC alerts you
with a visual and acoustic warning. There is a
risk of an accident.
Apply the brakes yourself in these situations
and try to take evasive action.
! When Distance Pilot DISTRONIC or the
HOLD function is activated, the vehicle
brakes automatically in certain situations.
To avoid damage to the vehicle, deactivate
DISTRONIC PLUS and the HOLD function in
the following or similar situations: R
when towing the vehicle R
in the car wash
If you fail to adapt your driving style, Distance
Pilot DISTRONIC can neither reduce the risk of
an accident nor override the laws of physics.
Distance Pilot DISTRONIC cannot take into
account road, weather or traffic conditions. Dis-
tance Pilot DISTRONIC is only an aid. You are
responsible for the distance to the vehicle in
front, for vehicle speed, for braking in good time
and for staying in your lane.
Do not use Distance Pilot DISTRONIC: R
in road and traffic conditions which do not
allow you to maintain a constant speed, e.g. in
heavy traffic or on winding roads R
on slippery road surfaces. Braking or accel-
erating could cause the drive wheels to lose
traction and the vehicle could then skid R
when there is poor visibility, e.g. due to fog,
heavy rain or snow Distance Pilot DISTRONIC may not detect nar-
row vehicles driving in front, e.g. motorcycles, or
vehicles driving on a different line.
In particular, the detection of obstacles can be
impaired if: R
there is dirt on the sensors or anything else
covering the sensors R
there is snow or heavy rain R
there is interference by other radar sources R
there are strong radar reflections, for exam-
ple, in parking garages
If Distance Pilot DISTRONIC no longer detects a
vehicle in front, it may unexpectedly accelerate
to the speed stored.
This speed may: R
be too high if you are driving in a filter lane or
an exit lane R
be so high when driving in the right-hand lane
that you overtake vehicles in the left-hand
lane R
be so high when driving in the left-hand lane
that you overtake vehicles in the right-hand
lane
If there is a change of drivers, advise the new
driver of the speed stored.

Selecting the drive program Distance Pilot DISTRONIC supports a sporty
driving style if you have selected the Sport or
Sport Plus drive program ( Y
page 143). Accel-
eration behind the vehicle in front or to the set
speed is then noticeably more dynamic. If you
have selected the Comfort drive program, the
vehicle accelerates more gently. This setting is
recommended in stop-and-start traffic.
Changing lanes If you change to the overtaking lane, Distance
Pilot DISTRONIC supports you if: R
you are driving faster than 45 mph (70 km/h) R
you switch on the appropriate turn signal R
Distance Pilot DISTRONIC does not currently
detect a danger of collision
If these conditions are fulfilled, your vehicle is
accelerated. Acceleration will be interrupted if
changing lanes takes too long or if the distance
between your vehicle and the vehicle in front
becomes too small.
i When you change lanes, Distance Pilot
DISTRONIC monitors the right lane (in left-
side traffic) or the left lane (in right-side traf-
fic).
Stopping
G WARNING
When leaving the vehicle, even if it is braked
only by DISTRONIC PLUS, it could roll away if: R
there is a malfunction in the system or in
the voltage supply. R
DISTRONIC PLUS has been deactivated
with the cruise control lever, e.g. by a vehi-
cle occupant or from outside the vehicle. R
the electrical system in the engine com-
partment, the battery or the fuses have
been tampered with. R
the battery is disconnected. R
the accelerator pedal has been depressed,
e.g. by a vehicle occupant.
There is a risk of an accident.
If you wish to exit the vehicle, always turn off
DISTRONIC PLUS and secure the vehicle
against rolling away. If Distance Pilot DISTRONIC detects that the
vehicle in front is stopping, it brakes your vehicle
to a stop.
Once your vehicle is stationary, it remains sta-
tionary and you do not need to depress the
brake.
After a time, the electric parking brake secures
the vehicle and relieves the service brake.
Depending on the specified minimum distance,
your vehicle will come to a standstill at a suffi-
cient distance behind the vehicle in front. The
specified minimum distance is set using the
control on the cruise control lever.
The transmission is shifted automatically to
position P if, with Distance Pilot DISTRONIC
activated and the vehicle stationary: R
the driver's door is open and the driver's seat
belt is unfastened. R
the engine is switched off, unless it is auto-
matically switched off by the ECO start/stop
function.
The electric parking brake secures the vehicle
automatically if, with Distance Pilot DISTRONIC
activated and the vehicle stationary: R
a system malfunction occurs. R
the power supply is not sufficient.
On steep uphill or downhill inclines or if there is
a malfunction, the transmission may also be
automatically shifted into position P .
Setting a speed Keep in mind that it may take a brief moment
until the vehicle has accelerated or braked to
the speed set. X
Press the cruise control lever up C for a
higher speed or down
HOLD function
General notes The HOLD function can assist the driver in the
following situations: R
when pulling away, especially on steep slopes R
when maneuvering on steep slopes R
when waiting in traffic
The vehicle is kept stationary without the driver
having to depress the brake pedal.
The braking effect is canceled and the HOLD
function deactivated when you depress the
accelerator pedal to pull away.
i Do not use the HOLD function when driving
off-road, on steep uphill or downhill gradients
or on slippery or loose surfaces. The HOLD
function cannot hold the vehicle on such sur-
faces.

a parking space has been detected, an arrow
towards the right or the left also appears. Park-
ing Pilot displays only parking spaces on the
front-passenger side as standard. Parking
spaces on the driver's side are displayed as
soon as the turn signal on the driver's side is
activated. When parking on the driver's side,
this must remain activated until you confirm the
use of Parking Pilot by pressing the v button
on the multifunction steering wheel. The system
automatically determines whether the parking
space is parallel or at right angles to the direc-
tion of travel.
