Tips for driving with DISTRONIC PLUS
General notes
Pay particular attention in the following traffic
situations:
RCornering, going into and coming out of a
bend
RVehicles traveling onadifferent line
ROther vehicles changinglanes
RNarrow vehicles
RObstructions and stationary vehicles
RCrossing vehicles
In such situations, brake if necessary.
DISTRONIC PLUS is then deactivated.
Cornering, going into and coming out of a
bend
The ability of DISTRONIC PLUS to detect
vehicles when cornering is limited. Your
vehicle may brake unexpectedly or late.
Vehicles traveling onadifferent line
DISTRONIC PLUS may not detectvehicles
traveling onadifferent line. The distance to
the vehicle in frontwill be too short.

Z

Other vehicles changing lanes
DISTRONIC PLUS has not detected the
vehicle cutting in yet. The distancetothis
vehicle will be too short.
Narrow vehicles
DISTRONIC PLUS has not yet detected the
vehicle in frontonthe edge of the road,
because of its narrow width. The distance to
the vehicle in front will be too short.
Obstructions and stationary vehicles
DISTRONIC PLUS does not brake for
obstacles or stationary vehicles. If, for
example, the detected vehicle turnsacorner
and reveals an obstacle or stationary vehicle,
DISTRONIC PLUS will not brake for these.
Crossing vehicles
DISTRONIC PLUS may mistakenly detect
vehicles that are crossing your lane.
Activating DISTRONIC PLUS at traffic lights
with crossing traffic, for example, could cause
your vehicle to pull away unintentionally.
HOLD function
General notes
The HOLD function can assist the driver in the
following situations:
Rwhen pulling away,especiallyonsteep
slopes
Rwhen maneuvering on steep slopes
Rwhen 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.

Load compensation
The vehicle can compensatedifferences in
thevehicle level by raisingorlowering the
rear axle. This is the case, for example, if
people get out or if luggage is being loaded.
Load compensation takes place if:
Radoor or the trunk lid/tailgate is opened
Rthe parked vehicle is unlocked
For larger level changes, the engine must be
running.
4MATIC (permanent four-wheel drive)
If you fail to adapt your driving style, 4MATIC
can neither reduce the risk of accident nor
override the laws of physics. 4MATIC cannot
take account of road, weather and traffic
conditions. 4MATIC 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.
Ifadrive wheel spins due to insufficientgrip:
ROnly depress the accelerator pedalasfar
as necessary when pulling away.
RAccelerate less when driving.
!Never tow the vehiclewith one axle
raised. This may damage the transfer case.
Damageofthis sort is not covered by the
Mercedes-Benz Limited Warranty. All
wheels must remaineitheronthe ground
or be fully raised. Observe the instructions
for towing the vehicle with all wheels in full
contact with the ground.
iIn wintry driving conditions, the maximum
effect of 4MATIC can only be achieved if
you use winter tires(M+S tires), with snow
chains if necessary.
4MATIC ensures that allfour wheels are
permanently driven. Together with ESP®,it
improves the traction of yourvehicle
wheneveradrive wheel spins due to
insufficient grip.
