parking brake is being tested on a brake dyna-
mometer (maximum 10 seconds).
Braking triggered automatically by ESP ®
may
seriously damage the brake system.
All checks and maintenance work on the brake
system must be carried out at a qualified spe-
cialist workshop.
Have brake pads installed and brake fluid
replaced at a qualified specialist workshop.
If the brake system has only been subject to
moderate loads, you should test the functional-
ity of your brakes at regular intervals. To do so,
depress the brake pedal firmly when driving at a high speed. This improves the grip of the brake
pads.
You can find a description of Brake Assist (BAS)
on (Y page 67) or of BAS PLUS on (Y page 72).
Mercedes-Benz recommends that you only have
brake pads/linings installed on your vehicle
which have been approved for Mercedes-Benz
vehicles or which correspond to an equivalent
quality standard. Brake pads/linings which have not been approved for Mercedes-Benz vehicles
or which are not of an equivalent quality could
affect your vehicle's operating safety.
Mercedes-Benz recommends that you only use
brake fluid that has been specially approved for your vehicle by Mercedes-Benz, or which corre-
sponds to an equivalent quality standard. Brake fluid which has not been approved for
Mercedes-Benz vehicles or which is not of an
equivalent quality could affect your vehicle's
operating safety.
High-performance brake system
(Mercedes-AMG vehicles) The high-performance brake system is designed
for heavy loads. This may lead to noise when
braking. This will depend on:
R Speed
R Braking force
R Environmental conditions, such as tempera-
ture and humidity
The wear of individual components of the brake system, such as the brake pads/linings or brake discs, depends on the individual driving style
and operating conditions.
For this reason, it is impossible to state a mile-
age that will be valid under all circumstances. An
aggressive driving style will lead to high wear. You can obtain further information about this
from your authorized Mercedes-Benz Center.
New and replaced brake pads and discs only
reach their optimum braking effect after several
hundred kilometers of driving. Compensate for
this by applying greater force to the brake pedal. Keep this in mind, and adapt your driving and
braking accordingly during this break-in period.
Excessive heavy braking results in correspond-
ingly high brake wear. Observe the 0026brake
wear warning lamp in the instrument cluster and
note any brake status messages in the multi-
function display. Especially for high perform-
ance driving, it is important to maintain and have
the brake system checked regularly. Driving on wet roads
Hydroplaning If water has accumulated to a certain depth on
the road surface, there is a danger of hydro-
planing occurring, even if:
R you drive at low speeds
R the tires have adequate tread depth
For this reason, in the event of heavy rain or in
conditions in which hydroplaning may occur,
you must drive in the following manner:
R lower your speed
R avoid ruts
R avoid sudden steering movements
R brake carefully
Driving on flooded roads !
Do not drive through flooded areas. Check
the depth of any water before driving through
it. Drive slowly through standing water. Oth-
erwise, water could enter the vehicle interior
or engine compartment. It can then damage
the engine's or automatic transmission's
electronic components. It can also be sucked
in by the engine's air intake connection and
cause engine damage.
i Vehicles with the AIRMATIC Package:
select the raised vehicle level before driving
through a body of water. Driving tips
163Driving and parking Z

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:
R The Off-road drive program (vehicles without
Off-Road Engineering package)
(Y page 215)
R Off-road andOff-road Plus drive programs
(vehicles with Off-Road Engineering package) (Y page 216)
R LOW RANGE off-road gear (vehicles with the
Off-Road Engineering package)
(Y page 217)
R Differential lock (vehicles with the Off-Road
Engineering package) (Y page 217)
R Off-road ABS (Y page 67)

Observe the following notes:
R Stop the vehicle before starting to drive along
an off-road route. If necessary, select the off- road program (Y page 216) or shift to the
LOW RANGE off-road gear (Y page 217).
R Select a vehicle level that is suitable for the
terrain. To avoid damaging the vehicle, make
sure there is always sufficient ground clear-
ance.
R Check that items of luggage and loads are
stowed safely and are well secured
(Y page 299).
R Always keep the engine running and in gear
when driving on a downhill gradient. Activate
DSR (Y page 214).
R Always keep the engine running and in gear
when driving down an incline.
R Adapt your speed to the terrain. The rougher,
steeper or more ruts on the terrain, the slower your speed should be.
R Do not jump with the vehicle as this will inter-
rupt the vehicle's propulsion.
R Drive 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. R
Look out for obstacles, such as rocks, holes,
tree stumps and furrows.
R Take care when turning on an uphill or down-
hill slope or when driving across a slope. The
vehicle could otherwise tip over.
R Always keep the doors, the tailgate, the side
windows and the sliding sunroof closed while
the vehicle is in motion.
R Do not shift the automatic transmission to
position 005C.
R Observe the notes on off-road fording
(Y page 164).
i Information about retrofitting special all-ter-
rain tires is available from any qualified spe-
cialist workshop.
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.
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.
X Engine 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.
X DEF tank (BlueTEC vehicles): check the
level and add if necessary (Y page 153).
X Tire-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.
X Wheels and tires: check the tread depth and
pressure of the tires.
X Check for damage and remove any foreign
objects, e.g. small stones, from the wheels/
tires.
X Replace any missing valve caps.
X Replace dented or damaged wheels.
X Rims: dented or bent rims can result in a loss
of tire pressure and damage the tire bead. 166

General notes Active Distance Assist DISTRONIC regulates the
speed and automatically helps you maintain the
distance from the vehicle detected in front.
Vehicles are detected with the aid of the radar
sensor system. Active Distance Assist
DISTRONIC brakes automatically so that the set
speed is not exceeded.
You must select a lower gear in good time on
long and steep downhill gradients, especially if
the vehicle is laden or towing a trailer. By doing so, you will make use of the braking effect of theengine. This relieves the load on the brake sys-
tem and prevents the brakes from overheating
and wearing too quickly.
If Active Distance Assist DISTRONIC detects
that there is a risk of a collision with the vehicle
in front, you will be warned visually and audibly.
Active Distance Assist DISTRONIC cannot pre-
vent a collision without your intervention. An
intermittent warning tone will then sound and
the distance warning lamp will light up in the
instrument cluster. Brake immediately in order to increase the distance to the vehicle in front or
take evasive action provided it is safe to do so.
For Active Distance Assist DISTRONIC to assist you when driving, the radar sensor system must
be operational.
Active Distance Assist DISTRONIC operates in
the speed range between 0 mph (0 km/h) and
120 mph (200 km/h).
Do not use Active Distance Assist DISTRONIC
while driving on roads with steep gradients.
As Active Distance Assist DISTRONIC transmits
radar waves, it can resemble the radar detectors of the responsible authorities. You can refer to
the relevant chapter in the Operator's Manual ifquestions are asked about this.

Tips for driving with Active Distance
Assist DISTRONIC General notes
Pay particular attention in the following traffic
situations:
R Cornering, entering and exiting a bend: the
ability of Active Distance Assist DISTRONIC to detect vehicles on bends is limited. Your vehi-cle may brake unexpectedly or late.
R Vehicles driving in a staggered formation:
Active Distance Assist DISTRONIC may not
detect vehicles that are not driving in the mid- dle of their lanes. The distance to the vehiclein front will be too short.
R Other vehicles changing lane: Active Distance
Assist DISTRONIC has not detected the vehi-
cle cutting in yet. The distance to this vehicle
will be too short.
R Narrow vehicles: Active Distance Assist
DISTRONIC has not yet detected the vehicle
in front on the edge of the road because of its
narrow width. The distance to the vehicle in
front will be too short.
R Obstacles and stationary vehicles: Active Dis-
tance Assist DISTRONIC does not brake for obstacles or stationary vehicles. If, for exam-
ple, the detected vehicle turns a corner and
an obstacle or stationary vehicle is revealed,
Active Distance Assist DISTRONIC will not
brake for them.
R Crossing vehicles: Active Distance Assist
DISTRONIC may mistakenly detect vehicles
that are crossing your lane. Activating Active
Distance Assist DISTRONIC at, for example, a
traffic light with crossing traffic could cause
your vehicle to pull away at the wrong time.
In such situations, brake if necessary. Active
Distance Assist DISTRONIC will then be deacti-
vated.
Active Distance Assist DISTRONIC with
Active Steering Assist General notes
Active Distance Assist DISTRONIC with Active
Steering Assist aids you in keeping the vehicle in
the center of the driving lane by means of mod-
erate steering interventions in a speed range
from 0 - 125 mph (0 - 200 km/h).
It monitors the area in front of your vehicle by
means of camera system 0043at the top of the
windshield.
In a speed range from 0 - 37 mph (0 - 60 km/h),
the advanced automatic pulling away function
focuses on the vehicle in front, taking into
account lane markings, e.g. when following vehi-
cles in a traffic jam.
At speeds of more than 37 mph (60 km/h),
Active Steering Assist focuses on clear lane
markings (left and right), focusing on the vehicle
in front only if clear lane markings are not pres-
ent.
If these conditions are not present, Active Steer-
ing Assist cannot provide assistance. Driving systems
177Driving and parking Z

Active Distance Assist DISTRONIC must be
active in order for the function to be available.
Important safety notes
Active Distance Assist DISTRONIC with Active
Steering Assist can neither reduce the risk of an accident if you fail to adapt your driving style,
nor override the laws of physics. It cannot take
into account road, weather or traffic conditions.Active Distance Assist DISTRONIC with Active
Steering Assist is only an aid. You are responsi-
ble for the distance to the vehicle in front, for
vehicle speed, for braking in good time and for
staying in your lane.
Active Distance Assist DISTRONIC with Active
Steering Assist does not detect road and traffic conditions and does not detect all road users. If
you are following a vehicle which is driving
towards the edge of the road, your vehicle 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.
Active Distance Assist DISTRONIC with Active
Steering Assist cannot continuously keep your
vehicle in lane. In some cases, the steering
intervention is not sufficient to bring the vehicleback 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 heavy spray
R there is glare, e.g. from oncoming traffic, the
sun or reflection from other vehicles (e.g. if
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 or several unclear lane markings
for one lane, e.g. roadworks
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 short
and thus the lane markings 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 highly variable shade conditions on
the roadway
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 you take your hands off the steering wheel or
do not steer for a prolonged period of time
i Once you have finished changing lanes,
Active Steering Assist automatically reacti-
vates.
Active Steering Assist cannot provide assis-
tance: R on very sharp corners
R when towing a trailer
R when a loss of tire pressure or a defective tire
has been detected and displayed
Observe the important safety notes on Active
Distance Assist DISTRONIC (Y page 172).
The steering interventions are carried out with 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. Active Steering
Assist is then switched to passive. Active Dis-
tance Assist DISTRONIC remains active.

Road Engineering package)
Important safety notes Level control adapts the vehicle level automati-
cally to the current operating and driving situa-
tion. This results in reduced fuel consumption
and improved handling.
Make changes to the vehicle level while the
vehicle is in motion. This enables the vehicle to adjust to the new level as quickly as possible.
The vehicle level may change visibly if you park
the vehicle and the outside temperature
changes. If the temperature drops, the vehicle
level is lower; with an increase in temperature,
the vehicle level rises.
If you unlock the vehicle or open a door, the
vehicle begins to compensate for load discrep-
ancies while still parked. However, for signifi-
cant level changes, such as after the vehicle has
been stationary for a long period, the engine
must be on. For safety reasons, the vehicle is
only lowered when the doors are closed. Low- ering is interrupted if a door is opened, and it
continues once the door has been closed.
Further information about "Driving off-road"
(Y
page 165). G
WARNING
When the vehicle is being lowered, people
could become trapped if their limbs are
between the vehicle body and the wheels or
underneath the vehicle. There is a risk of
injury.
Make sure no one is underneath the vehicle or in the immediate vicinity of the wheel arches
when the vehicle is being lowered. G
WARNING
When you drive with the vehicle raised, the
driving characteristics could be impaired by
the vehicle's raised center of gravity. The vehi- cle could rollover more easily, for example on
a bend. There is a risk of an accident.
Always select as low a vehicle level as possi-
ble and adjust your driving style. G
WARNING
When you drive with the chassis lowered or
raised, the vehicle's braking and driving char-
