180Driving tips
Driving and parking

RActivate 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.
RCheck that the brakes are working normally
after a long downhill stretch.
Off-road ABS is activated when the off-road
program is selected.
At speeds below 18 mph (30 km/h), the front
wheels lock cyclically during braking. The dig-
ging-in effect achieved in the process reduces the stopping distance on off-road terrain. The
steerability of the vehicle is considerably
reduced if the wheels lock.
Driving systems
Cruise Control
General notes
Cruise control maintains a constant road
speed for you. It brakes automatically in order to avoid exceeding the set speed. On long and
steep downhill gradients, especially if the
vehicle is laden, you must select a low gear in
good time. You need to have previously selec-
ted manual gearshifting M(
Ypage 166). By
doing so, you will make use of the braking
effect of the engine. This relieves the load on
the brake system and prevents the brakes
from overheating and wearing too quickly.
Use cruise control only if road and traffic con-
ditions make it appropriate to maintain a
steady speed for a prolonged period. You can
store any road speed above 20 mph
(30 km/h).
The speed indicated in the speedometer may
differ slightly from the speed stored.
Important safety notes
If you fail to adapt your driving style, cruise
control can neither reduce the risk of an acci-
dent nor override the laws of physics. Cruise
control cannot take into account the road,
traffic and weather conditions. Cruise control is only an aid. You are responsible for the dis-
tance to the vehicle in front, for vehicle speed,
for braking in good time and for staying in
your lane.
Do not use cruise control:
Rin road and traffic conditions which do not
allow you to maintain a constant speed e.g.
in heavy traffic or on winding roads
Ron slippery road surfaces. Braking or accel-
erating could cause the drive wheels to lose
traction and the vehicle could then skid
Rwhen there is poor visibility, e.g. due to fog,
heavy rain or snow
If there is a change of drivers, advise the new
driver of the speed stored.

Storing, maintaining and calling up a
speed
Storing and maintaining the current
speed
You can store the current speed if you are
driving faster than 20 mph (30 km/h).
XAccelerate the vehicle to the desired
speed.
XBriefly press the cruise control lever up:
or down ?.
XRemove your foot from the accelerator
pedal.
Cruise control is activated. The vehicle
automatically maintains the stored speed.
iCruise control may be unable to maintain
the stored speed on uphill gradients. The
stored speed is resumed when the gradient
evens out. Cruise control maintains the
stored speed on downhill gradients by
automatically applying the brakes.
Storing the current speed or calling up the
last stored speed
GWARNING
If you call up the stored speed and it differs
from the current speed, the vehicle acceler-
ates or decelerates. If you do not know the
stored speed, the vehicle could accelerate or brake unexpectedly. There is a risk of an acci-
dent.
Pay attention to the road and traffic condi-
tions before calling up the stored speed. If you
do not know the stored speed, store the
desired speed again.
XBriefly pull the cruise control lever towards
you =.
XRemove your foot from the accelerator
pedal.
The first time cruise control is activated, it
stores the current speed or regulates the
speed of the vehicle to the previously
stored speed.
Setting a speed
Keep in mind that it may take a brief moment
until the vehicle has accelerated or braked to
the speed set.
XPress the cruise control lever up :for a
higher speed or down ?for a lower speed.
XTo adjust the set speed in 1 mph incre-
ments (1 km/h increments): briefly
press the cruise control lever up :or
down ?to the pressure point.
The last stored speed increases or decrea-
ses in 1 mph (1 km/h) increments.
XTo adjust the set speed in 5 mph incre-
ments (10 km/h increments): briefly
press the cruise control lever up :or
down ?to the pressure point.
The last stored speed increases or decrea-
ses in 5 mph (10 km/h) increments.
iCruise control is not deactivated if you
depress the accelerator pedal. For exam-
ple, if you accelerate briefly to overtake,
cruise control adjusts the vehicle's speed
to the last speed stored after you have fin- ished overtaking.
Deactivating cruise control
There are several ways to deactivate cruise
control:
XBriefly press the cruise control lever for-
wards =.
or
XBrake.
Cruise control is automatically deactivated if:
Rthe vehicle is secured with the electric
parking brake
Ryou are driving at less than 20 mph
(30 km/h)
RESP®intervenes or you deactivate ESP®
Ryou shift the transmission to position N
while driving
If cruise control is deactivated, you will hear a
warning tone. You will see the Cruise con‐

To prevent damage to the vehicle, deacti-
vate DISTRONIC PLUS and the HOLD func-tion in the following or other similar situa-
tions:
Rwhen towing the vehicle
Rin the car wash
If you fail to adapt your driving style,
DISTRONIC PLUS can neither reduce the risk
of accident nor override the laws of physics.
DISTRONIC PLUS cannot take into account
the road, traffic and weather conditions.
DISTRONIC PLUS 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 DISTRONIC PLUS:
Rin road and traffic conditions which do not
allow you to maintain a constant speed, e.g.
in heavy traffic or on winding roads
Ron slippery road surfaces. Braking or accel-
erating could cause the drive wheels to lose
traction and the vehicle could then skid
Rwhen there is poor visibility, e.g. due to fog,
heavy rain or snow
DISTRONIC PLUS may not detect narrow
vehicles driving in front, e.g. motorcycles, or
vehicles driving on a different line.
In particular, the detection of obstacles can
be impaired if:
Rthere is dirt on the sensors or anything else covering the sensors
Rthere is snow or heavy rain
Rthere is interference by other radar sources
Rthere are strong radar reflections, for
example, in parking garages
If DISTRONIC PLUS no longer detects a vehi- cle in front, DISTRONIC PLUS may unexpect-
edly accelerate the vehicle to the stored
speed. This speed may:
Rbe too high if you are driving in a filter lane
or an exit lane
Rbe so high when driving in the right-hand
lane that you overtake vehicles in the left-
hand lane
Rbe so high when driving in the left-hand lane
that you overtake vehicles in the right-hand
lane

Activating
XBriefly pull the cruise control lever towards
you ?, up :or down A.
DISTRONIC PLUS is selected.
XKeep the cruise control lever pressed up :
or down Auntil the desired speed is set.
XRemove your foot from the accelerator
pedal.
Your vehicle adapts its speed to that of the
vehicle in front, but only up to the desired
stored speed.
iIf you do not fully release the accelerator
pedal, the DISTRONIC
PLUSPassivemes-
sage appears in the multifunction display.
The set distance to a slower-moving vehicle
in front will then not be maintained. You will
be driving at the speed you determine by
the position of the accelerator pedal.
You can also activate DISTRONIC PLUS when
stationary. The lowest speed that can be set is
20 mph (30 km/h).
Driving with DISTRONIC PLUS
Pulling away and driving
The vehicle can also pull away when it is
facing an unidentified obstacle or is driving on a different line from another vehicle. The vehi-
cle then brakes automatically. Be ready to
brake at all times.
If you depress the brake, DISTRONIC PLUS is
deactivated unless your vehicle is stationary.
XIf you want to pull away with
DISTRONIC PLUS: remove your foot from
the brake pedal.
XBriefly pull the cruise control lever towards
you ?.
or
XAccelerate briefly.
Your vehicle pulls away and adapts its
speed to that of the vehicle in front.
If no vehicle is detected in front, your vehi-
cle accelerates to the set speed.
If there is no vehicle in front, DISTRONIC
PLUS operates in the same way as cruise
control.
If DISTRONIC PLUS detects that the vehicle in
front has slowed down, it brakes your vehicle.
In this way, the distance you have selected is
maintained.
If DISTRONIC PLUS detects a faster-moving
vehicle in front, it increases the driving speed.
The vehicle is only accelerated up to the
speed you have stored.
Selecting the drive program
DISTRONIC Plus supports a sporty driving
style whe
n you select the S+(Mercedes-AMG
vehicles only) or S(
Ypage 164 )drive program
or the manual gearshift (
Ypage 166). Accel-
eration behind the vehicle in front or to the set
speed is then noticeably more dynamic. If you
have selected the E(Mercedes-AMG vehicles:
C ) drive program, the vehicle accelerates
more gently. This setting is recommended in
stop-and-start traffic.
Changing lanes
If you change to the passing lane, DISTRONIC
PLUS supports you when:
Ryou are driving faster than 43 mph
(70 km/h)
RDISTRONIC PLUS is maintaining the dis-
tance to a vehicle in front
Ryou switch on the appropriate turn signal
RDISTRONIC PLUS does not detect a danger
of collision
