General notes
HEnvironmental note
Protection of the environment is of primary
importance. Treat nature with respect.
Observe all prohibiting signs.
Read this section carefully before driving your
vehicle off-road. Practice by driving over more
gentle off-road terrain first.
Familiarize yourself with the characteristics of
your vehicle and the gear shift operation before
driving through difficult terrain.
The following driving systems are specially
adapted to off-road driving:
R4ETS (Ypage 59)
ROff-road ABS (Ypage 59)
RTransfer case (Ypage 149)
RDifferential locks (Ypage 151)
Observe the following notes:
Rstop the vehicle before you drive off-road and,
if necessary, shift the transfer case to the
LOW RANGE off-road gear (
Ypage 149).
REngage the differential locks if necessary
(Ypage 151).
iABS, 4ETS, ESP®and BAS are deactivated
while the differential locks are engaged. This
allows the front wheels to lock briefly, so that
these can dig into a loose surface. However,
please note that locked wheels skid and can
no longer steer.
RCheck that items of luggage and loads are
stowed safely and are well secured
(
Ypage 214).
RTo avoid damaging the vehicle, make sure
there is always sufficient ground clearance.
RAlways keep the engine running and in gear
when driving on a downhill gradient.
RAlways keep the engine running and in gear
when driving down an incline.
RDrive slowly and evenly, if necessary at a
walking pace.
REnsure that the wheels are in contact with the
ground at all times.
RDrive with extreme care on unfamiliar off-road
routes where visibility is poor. For safety rea-
sons, get out of the vehicle first and survey
the off-road route.
RCheck the depth of water before fording rivers
and streams.
RWatch out for obstacles.
RAlways keep the doors, rear door, side win-
dows and the sliding sunroof closed while the
vehicle is in motion.
RSwitch off cruise control.
RDo not deviate from marked routes.
RAdapt your speed to the terrain. The rougher,
steeper or more ruts on the terrain, the slower
your speed should be.
RDo not jump with the vehicle. as this will inter-
rupt the vehicle's propulsion.
RAvoid high engine speeds. Drive at appropri-
ate engine speeds (maximum 3,000 rpm).
RDo not shift the automatic transmission to
position i.
RAlways check the vehicle for damage after off-
road driving.
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 surfaces.
You can obtain further information about mount-
ing special all-terrain tires from a qualified spe-
cialist workshop.
Checklist before driving off-road
!If the engine oil warning lamp lights up while
the vehicle is in motion, stop the vehicle in a
safe place as soon as possible. Check the
engine oil level. The engine oil warning lamp
warning must not be ignored. Continuing the
journey while the symbol is displayed could
lead to engine damage.
XEngine oil level: check the engine oil level
and add oil if necessary.
When driving on steep gradients, the engine
oil level must be sufficiently high to ensure a
correct oil supply in the vehicle.
XTire-changing tool kit: check that the jack is
working and make sure you have the lug
wrench, a robust tow cable and a folding
spade in the vehicle.
XWheels and tires: check the tire tread depth
and tire pressure.
XCheck for damage and remove any foreign
objects, e.g. small stones, from the wheels/
tires.
XReplace any missing valve caps.
130Driving tips
Driving and parking

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.
!Drive with particular care when driving over
an obstacle while driving up or down a steep
slope.
The vehicle could otherwise tilt and slide side-
ways or tip over.
Observe the following rules when driving over
tree stumps, large stones and other obstacles:
RObserve the safety notes (Ypage 129) and
the general notes (Ypage 130) on off-road
driving.
RShift the transfer case to the off-road driving
position LOW RANGE (Ypage 149).
RAvoid high engine speeds.
RShift the automatic transmission to a low
gear.
RMake sure that you have enough ground
clearance before driving across an obstacle.
RDrive very slowly.
RTry to drive straight over the center of obsta-
cles: front wheel first, then rear wheel.
Traveling uphill
Approach/departure angle
GWARNING
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.
Always observe the approach/departure angle
values (
Ypage 290).
RObserve the safety notes (Ypage 129) and
general notes (Ypage 130) on driving off-
road.
RDo not drive at an angle on slopes, inclines or gradients, but instead follow the direct line of
fall. Note that the climbing ability of your vehi- cle depends on the terrain conditions.
RBefore driving on extreme uphill and downhill
gradients, shift the transfer case to the LOW
RANGE off-road gear (
Ypage 149).
REngage the differential locks if necessary
(Ypage 151).
RDrive slowly.
RAccelerate gently and make sure that the
wheels are gripping.
RAvoid high engine speeds, except when driv-
ing on sandy and muddy routes with high driv-
ing resistance.
RAvoid high engine speeds – drive at an appro-
priate engine speed (maximum 3,000 rpm).
RWhen driving down an incline, make use of the
engine's bra king effect. Observe the engine
speed; do not overrev the engine.
Further information on the maximum engine
speed (
Ypage 160).
RShift the automatic transmission to a low gear appropriate for tackling an uphill gradient or a
long, steep downhill gradient.
Hill start assist will aid you when pulling away on
a hill. For further information about hill start
assist, see (
Ypage 107).
Maximum gradient-climbing capability
Always observe the maximum gradient climbing ability values (Ypage 290).
Hilltops
When driving up an uphill gradient, slightly
reduce pressure on the accelerator immediately
before reaching the brow of the hill (do not shift
the transmission into N). Make use of the vehi-
cle's own impetus to travel over the brow.
This style of driving prevents:
Rthe vehicle from lifting off the ground on the
brow of a hill
Rloss of traction
Rthe vehicle from traveling too quickly down
the other side
Driving downhill
RDrive slowly.
RDo 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.
132Driving tips
Driving an d parking

RBefore tackling steep downhill gradients, shift
the automatic transmission to a low gear.
By doing so, you will use the braking effect of
the engine to reduce the speed. 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.
RObserve the notes on driving in mountainous
terrain (Ypage 132).
RCheck that the service brake is working nor-
mally after a long downhill stretch.
When driving at speeds below 37 mph
(60 km/h), off-road ABS is activated and the
front wheels lock cyclically during braking. The
digging-in effect achieved in the process
reduces the stopping distance on off-road ter-
rain. This limits steering capability.
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. Change into a lower
gear in good time on long and steep downhill
gradients.
This is especially important if the vehicle is
laden. 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).
Do not activate cruise control on off-road jour-
neys.
Important safety notes
Cruise control can neither reduce the risk of an
accident if you fail to adapt your driving style nor override the laws of physics. Cruise control can-
not take into account the road, traffic and
weather conditions. Cruise control is only an
aid. You are responsible for maintaining a safe
distance to the vehicle in front, for vehicle
speed, for braking in good time and for staying in
lane. Do not use cruise control:
Rin road and traffic conditions that do not allow
you to maintain a constant speed, e.g. in
heavy traffic, on winding roads or on rough
terrain
Ron slippery road surfaces. Braking or accel-
erating could cause the drive wheels to lose
traction and the vehicle could then skid
Rin 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.
iThe speed indicated in the speedometer
may differ slightly from the speed stored.

XRemove your foot from the accelerator pedal.
Cruise control is activated. The vehicle auto-
matically maintains the stored speed.
iCruise control may be unable to maintain
the stored speed on uphill and downhill gra-
dients. The stored speed is resumed when the
gradient levels out. Cruise control maintains
the stored speed on downhill gradients by
automatically applying the brakes.
Calling up the stored speed
GWARNING
If you call up the stored speed and it is lower
than the current speed, the vehicle deceler-
ates. If you do not know the stored speed, the vehicle could decelerate unexpectedly. There
is a risk of an accident.
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.
Cruise control is activated and adjusts the
vehicle's speed to the last speed stored.
If no speed is stored, cruise control stores the
current speed and maintains it.

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

increased or reduced.
iCruise control is not deactivated if you
depress the accelerator pedal. If you acceler-
ate to overtake, cruise control adjusts the
vehicle's speed to the last speed stored after
you have finished overtaking.
Deactivating cruise control
There are several ways to deactivate cruise con-
trol:
XBriefly press the cruise control lever forwards
=.
or
XBrake.
Cruise control is automatically deactivated if:
Ryou apply the parking brake
Ryou are driving at less than 20 mph (30 km/h)

Ryou shift the automatic transmission to posi-
tion iwhile driving
Ryou engage a differential lock
If cruise control is deactivated, a warning tone
sounds. You will see the Cruise Control Off
message in the multifunction display for approx-
imately five seconds. The message on the mul-
tifunction display disappears and the segments
on the speedometer go out.
iWhen you switch off the engine, the last
speed stored is cleared.
DISTRONIC PLUS
General notes
DISTRONIC PLUS regulates the speed and auto-
matically helps you maintain the distance from
the vehicle detected in front. Vehicles are detec-
ted with the aid of the radar sensor system.
DISTRONIC PLUS brakes automatically so that
the set speed is not exceeded.
Change into a lower gear in good time on long
and steep downhill gradients.
This is especially important if the vehicle is
laden. By doing so, you will make use of the
braking effect of the engine. This relieves the
134Driving systems
Driving an d parking

Do not use DISTRONIC PLUS:
Rin road and traffic conditions that 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 can 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 vehi-
cles driving in front, e.g. motorcycles, or vehi-
cles 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 exam-
ple, in parking garages
If DISTRONIC PLUS no longer detects a vehicle
in front, DISTRONIC PLUS may unexpectedly
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 in the right lane that you pass vehi-cles driving on the left (left-hand drive coun-
tries)
Rbe so high in the left lane that you pass vehi-
cles driving on the right (right-hand drive
countries)
If there is a change of drivers, advise the new
driver of the speed stored.

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.
DISTRONIC PLUS is activated. The first time it
is activated, the current speed is stored. Oth-
erwise, it sets the vehicle speed to the previ-
ously stored value.
Driving with DISTRONIC PLUS
Pulling away and driving
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.
The vehicle pulls away and adapts its speed to that of the vehicle in front. If no vehicle is
detected in front, your vehicle accelerates to
the stored speed.
The vehicle can also pull away when it is facing
an unidentified obstacle or is driving on a differ- ent line from another vehicle. The vehicle then
brakes automatically.
If DISTRONIC PLUS does not detect a vehicle in
front, the system operates like a cruise control.
If DISTRONIC PLUS detects that the vehicle in
front is driving slower, your vehicle brakes. In this way, the specified minimum distance you
have selected is maintained.
If DISTRONIC PLUS detects a faster-moving
vehicle in front, it increases the driving speed to
the set speed.
If you depress the brake, DISTRONIC PLUS is
deactivated unless your vehicle is stationary.
Selecting the drive program
DISTRONIC PLUS supports a sporty driving style
when you have selected the
Sdriving program
(
Ypage 116). Acceleration behind the vehicle in
front or to the set speed is then noticeably more dynamic. If you have selected drive program Eor
C (Mercedes-AMG vehicles), the vehicle accel-
erates more gently. This setting is recommen-
ded in stop-start traffic.
Changing lanes
If you change to the passing lane, DISTRONIC
PLUS supports you when:
Ryou are driving faster than 40 mph (60 km/h)
RDISTRONIC PLUS is maintaining the distance
to a vehicle in front
Ryou switch on the appropriate turn signal
RDISTRONIC PLUS does not 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.
When changing lanes, DISTRONIC PLUS moni-
tors the left lane on left-hand drive vehicles and
the right lane on right-hand drive vehicles.
Stopping
GWARNING
When leaving the vehicle, even if it is braked
only by DISTRONIC PLUS, it could roll away if:
Rthere is a malfunction in the system or in
the voltage supply.
RDISTRONIC PLUS has been deactivated
with the cruise control lever, e.g. by a vehi-
cle occupant or from outside the vehicle.
Rthe electrical system in the engine com-
partment, the battery or the fuses have
been tampered with.
Driving systems137

Rthe battery is disconnected.
Rthe 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.
For further information on deactivating
DISTRONIC PLUS (
Ypage 139).
If DISTRONIC PLUS detects that the vehicle in
front is stopping, it brakes your vehicle until it is
stationary.
Once your vehicle is stationary, it remains sta-
tionary and you do not need to depress the
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 automatic transmission shifts automatically
to transmission position jif DISTRONIC PLUS
is activated and:
Rthe driver's seat belt is not fastened and the
driver's door is open.
Rthe engine is switched off, unless it is auto-
matically switched off by the ECO start/stop
function.
On steep uphill or downhill inclines, or if there is
a malfunction, the automatic transmission may
also automatically be shifted to pos
ition

Every time the cruise control lever is pressed
up : or down ;, the last speed stored is
increased or reduced. If you accelerate to overtake, DISTRONIC PLUS
adjusts the vehicle's speed back to the last
speed stored after you have finished overtaking.
Setting a specified minimum distance
You can set the specified minimum distance for
DISTRONIC PLUS by varying the time span
between one and two seconds. With this func-
tion, you can set the minimum distance that
DISTRONIC PLUS keeps to the vehicle in front,
dependent on vehicle speed. You can see this
distance in the multifunction display
(
Ypage 167).
Make sure that you maintain the minimum dis-
tance to the vehicle in front as required by law.
Adjust the distance to the vehicle in front if nec-
essary.
XTo increase: turn control;in direction =.
DISTRONIC PLUS then maintains a greater
distance between your vehicle and the vehicle
in front.
XTo decrease: turn control;in direction :.

HOLD function
General notes
The HOLD function can assist the driver in the
following situations:
Rwhen pulling away, especially on steep 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.
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 surfaces.
Important safety notes
GWARNING
If the vehicle is only braked using the HOLD
function, the vehicle may roll away in the fol-
lowing situations when you leave the vehicle:
Rif there is a malfunction in the system or in the voltage supply
Rif the HOLD function is deactivated by
depressing the accelerator pedal or brake
pedal, e.g. by a vehicle occupant
Rif the electrical system in the engine com-
partment, the battery or the fuses are tam-
pered with or the battery is disconnected
There is a risk of an accident.
Always deactivate the HOLD function and
secure the vehicle against rolling away before
you leave it.
!When DISTRONIC PLUS or the HOLD func-
tion is activated, the vehicle brakes automat-
ically in certain situations.
To avoid damage to the vehicle, deactivate
DISTRONIC PLUS and the HOLD function in
the following or similar situations:
