reacting to moving objects that have alreadybeen detected as such at least once over theperiod of observation.
Up to a speed of approximately 44 mph(70 km/h), Adaptive Brake Assist reacts to sta-tionary obstacles.
If adaptive Brake Assist demands particularlyhigh braking force, preventative passenger pro-
tection measures (PRE-SAFE®) are activatedsimultaneously (Ypage 57).
XKeep the brake pedal depressed until theemergency braking situation is over.ABS prevents the wheels from locking.
The brakes will work normally again if:
Ryou release the brake pedal
Rthere is no longer any danger of a collision
Rno obstacle is detected in front of your vehicle
Adaptive Brake Assist is then deactivated.
Important safety notes
iObserve the "Important safety notes" sec-tion for driving safety systems (Ypage 65).
GWARNING
Adaptive Brake Assist cannot always clearly
identify objects and complex traffic situa-
tions.
In such cases, Adaptive Brake Assist can:
Rintervene unnecessarily
Rnot intervene
There is a risk of an accident.
Always pay careful attention to the traffic sit-
uation and be ready to brake. Terminate the
intervention in a non-critical driving situation.
GWARNING
Adaptive Brake Assist does not react:
Rto people or animals
Rto oncoming vehicles
Rto crossing traffic
Rwhen cornering
As a result, the Adaptive Brake Assist may not
intervene in all critical conditions. There is a
risk of an accident.
Always pay careful attention to the traffic sit-
uation and be ready to brake.
Always adapt your speed to suit the prevailing
road and traffic conditions.
Due to the nature of the system, particularlycomplicated but non-critical driving conditionsmay also cause Brake Assist to intervene.
If adaptive Brake Assist is not available due to amalfunction in the radar sensor system, thebrake system remains available with full brakeboosting effect and BAS.
ESP®(Electronic Stability Program)
General notes
iObserve the "Important safety notes" sec-tion (Ypage 65).
ESP®monitors driving stability and traction, i.e.power transmission between the tires and theroad surface.
If ESP®detects that the vehicle is deviating fromthe direction desired by the driver, one or morewheels are braked to stabilize the vehicle. Theengine output is also modified to keep the vehi-cle on the desired course within physical limits.
ESP®assists the driver when pulling away on
wet or slippery roads. ESP®can also stabilizethe vehicle during braking.
4ETS (Electronic Traction System)
iObserve the "Important safety notes" sec-tion (Ypage 65).
ETS traction control is part of ESP®. On vehicles
with 4MATIC, 4ETS is part of ESP®.
Traction control brakes the drive wheels indi-vidually if they spin. This enables you to pullaway and accelerate on slippery surfaces, forexample if the road surface is slippery on oneside. In addition, more drive torque is transfer-red to the wheel or wheels with traction.
Traction control remains active, even if you
deactivate ESP®.

braking maneuvers. Do not use cruise control orActive Distance Assist DISTRONIC.
If the vehicle threatens to skid or cannot bestopped when moving at low speed:
XShift the transmission to position\\.
The outside temperature indicator is notdesigned to serve as an ice-warning device andis therefore unsuitable for that purpose.Changes in the outside temperature are dis-played after a short delay.
Indicated temperatures just above the freezingpoint do not guarantee that the road surface isfree of ice. The road may still be icy, especially inwooded areas or on bridges. The vehicle couldskid if you fail to adapt your driving style. Alwaysadapt your driving style and drive at a speed tosuit the prevailing weather conditions.
You should pay special attention to road condi-tions when temperatures are around freezingpoint.
For more information on driving with snowchains, see (Ypage 332).
For more information on driving with summertires, see (Ypage 332).
Observe the notes in the "Winter operation" sec-tion (Ypage 332).
Driving systems
Mercedes-Benz Intelligent Drive
Mercedes-Benz Intelligent Drive stands for inno-vative driver assistance and safety systemswhich enhance comfort and support the driver incritical situations. With these intelligent coordi-nated systems Mercedes-Benz has set a mile-stone on the path towards autonomous driving.
Mercedes-Benz Intelligent Drive embraces allelements of active and passive safety in one wellthought out system – for the safety of the vehi-cle occupants and that of other road users.
Further information on driving safety systems(Ypage 65).
Cruise control
General notes
Cruise control maintains a constant road speedfor you. It brakes automatically in order to avoidexceeding the set speed. Change into a lower
gear in good time on long and steep downhillgradients. This is especially important if thevehicle 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 overheatingand wearing too quickly.
Use cruise control only if road and traffic con-ditions make it appropriate to maintain a steadyspeed for a prolonged period. You can store anyroad speed above 20 mph (30 km/h).
Important safety notes
Cruise control can neither reduce the risk of anaccident if you fail to adapt your driving style noroverride the laws of physics. Cruise control can-not take into account the road, traffic andweather conditions. Cruise control is only anaid. You are responsible for maintaining a safedistance to the vehicle in front, for vehiclespeed, for braking in good time and for staying inlane.
Do not use cruise control:
Rin road and traffic conditions which do notallow you to maintain a constant speed, e.g. inheavy traffic or on winding roads
Ron slippery road surfaces. Braking or accel-erating could cause the drive wheels to losetraction 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 newdriver of the speed stored.
iThe speed indicated in the speedometermay differ slightly from the speed stored.

possible deceleration. If this deceleration is
not sufficient, Active Distance Assist
DISTRONIC alerts you with a visual and acous-
tic warning. There is a risk of an accident.
Adjust your speed in these cases and main-
tain sufficient distance. Apply the brakes
yourself and try to take evasive action.
!When Active Distance Assist DISTRONIC orthe HOLD function is activated, the vehiclebrakes automatically in certain situations.
To avoid damage to the vehicle, deactivateActive Distance Assist DISTRONIC and theHOLD function in the following or similar sit-uations:
Rwhen towing the vehicle
Rin the car wash
Active Distance Assist DISTRONIC can neitherreduce the risk of an accident if you fail to adaptyour driving style, nor override the laws of phys-ics. Active Distance Assist DISTRONIC cannottake into account road, weather or traffic con-ditions. Active Distance Assist DISTRONIC isonly an aid. You are responsible for maintaininga safe distance to the vehicle in front, for vehiclespeed, for braking in good time and for staying inlane.
Do not use Active Distance Assist DISTRONIC:
RIn road and traffic conditions which do notallow you to maintain a constant speed, e.g. inheavy traffic or on winding roads
ROn slippery road surfaces. Braking or accel-erating could cause the drive wheels to losetraction and the vehicle could then skid
RIn poor visibility, e.g. due to fog, heavy rain orsnow
Active Distance Assist DISTRONIC may notdetect narrow vehicles driving in front, e.g.motorcycles, or vehicles driving in a staggeredformation.
In particular, the detection of obstacles can beimpaired if:
RThere is dirt on the sensors or anything elsecovering 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 Active Distance Assist DISTRONIC no longerdetects a vehicle in front, Distance Pilot
DISTRONIC may unexpectedly accelerate to thespeed stored.
This speed may:
RBe too high if you are driving in a turning laneor an exit lane
Rbe so high in the right lane that you pass vehi-cles driving on the left (in countries wherethey drive on the right)
Rbe so high in the left lane that you pass vehi-cles driving on the right (in countries wherethey drive on the left)

MOExtended tires (tires with run-flat
properties)
With MOExtended tires (tires with run flat char-acteristics), you can continue to drive your vehi-cle even if there is a total loss of pressure in oneor more tires.
MOExtended tires may only be used in conjunc-tion with an active tire pressure loss warningsystem or with an active tire pressure monitorand on wheels specifically tested by Mercedes-Benz.
Notes on driving with MOExtended tires with aflat tire (Ypage 315).
Vehicles equipped with MOExtended tires arenot equipped with a TIREFIT kit at the factory. Itis therefore recommended that you additionallyequip your vehicle with a TIREFIT kit if you mounttires that do not feature run-flat properties, e.g.winter tires. A TIREFIT kit can be obtained froma qualified specialist workshop.
Winter operation
General notes
Have your vehicle winter-proofed at a qualifiedspecialist workshop at the onset of winter.
Observe the notes in the "Changing a wheel"section (Ypage 350).
Driving with summer tires
At temperatures below 45 ‡ (+7 †), summertires lose elasticity and therefore traction andbraking power. Change the tires on your vehicleto M+S tires. Using summer tires at very coldtemperatures could cause cracks to form,thereby damaging the tires permanently.Mercedes-Benz cannot accept responsibility forthis type of damage.
GWARNING
Damaged tires can cause tire inflation pres-
sure loss. As a result, you could lose control of
your vehicle. There is a risk of accident.
Check the tires regularly for signs of damage
and replace any damaged tires immediately.
M+S tires
GWARNING

For safety reasons, Mercedes-Benz recom-mends that you only use snow chains that havebeen specially approved for your vehicle byMercedes-Benz, or are of a correspondingstandard of quality. For more information,please contact a qualified specialist workshop.
If you intend to mount snow chains, please bearthe following points in mind:
RSnow chains may not be mounted on allwheel/tire combinations. Observe the infor-mation regarding permitted wheel/tire com-binations (Ypage 354).
ROnly use snow chains when driving on roadscompletely covered by snow. Remove thesnow chains as soon as possible when youcome to a road that is not snow-covered.
RLocal regulations may restrict the use of snowchains. Observe the appropriate regulations ifyou wish to mount snow chains.
RDo not exceed the maximum permissiblespeed of 31 mph (50 km/h).
ROn vehicles with AIR BODY CONTROL, youmust only drive at raised vehicle level if snowchains have been installed (Ypage 172).
RWhen snow chains are installed, never useActive Parking Assist (Ypage 175).
You may wish to deactivate ESP®when pullingaway with snow chains installed:
RAll vehicles (except Mercedes‑AMG vehicles)(Ypage 69)
RMercedes‑AMG vehicles (Ypage 70)
You can thereby allow the wheels to spin in acontrolled manner, achieving an increased driv-ing force (cutting action).
Tire pressure
Tire pressure specifications
Important safety notes
GWARNING
Underinflated or overinflated tires pose the
following risks:
Rthe tires may burst, especially as the load
and vehicle speed increase.
Rthe tires may wear excessively and/or
unevenly, which may greatly impair tire
traction.
Rthe driving characteristics, as well as steer-
ing and braking, may be greatly impaired.
There is a risk of an accident.
Follow recommended tire inflation pressures
and check the pressure of all the tires includ-
ing the spare wheel:
Rmonthly, at least
Rif the load changes
Rbefore beginning a long journey
Runder different operating conditions, e.g.
off-road driving
If necessary, correct the tire pressure.
The data on the Tire and Loading Informationplacard and tire pressure table shown here areexamples. Tire pressure specifications are vehi-cle-specific and may deviate from the datashown here. The tire pressure specificationsthat are valid for your vehicle can be found onthe Tire and Loading Information placard andtire pressure table on the vehicle.
General notes
The recommended tire pressures for the tiresmounted at the factory can be found on thelabels described here.

iThe actual values for tires are vehicle-spe-cific and may deviate from the values in theillustration.
Treadwear
The treadwear grade is a comparative ratingbased on the wear rate of the tire when testedunder controlled conditions on a specified U.S.government course. For example, a tire graded150 would wear one and one-half times as wellon the government course as a tire graded 100.
The relative performance of tires depends uponthe actual conditions of their use, however, andmay depart significantly from the norm due tovariations in driving habits, service practicesand differences in road characteristics and cli-mate.
Traction
GWARNING
The traction grade assigned to this tire is
based on straight-ahead braking traction
tests, and does not include acceleration, cor-
nering, hydroplaning, or peak traction char-
acteristics.
!Avoid wheelspin. This can lead to damage tothe drive train.
The traction grades – from highest to lowest –are AA, A, B and C. Those grades represent thetire's ability to stop on wet pavement as meas-ured under controlled conditions on specifiedgovernment test surfaces of asphalt and con-crete. A tire marked C may have poor tractionperformance.
The safe speed on a wet, snow covered or icyroad is always lower than on dry road surfaces.
You should pay special attention to road condi-tions when temperatures are around freezingpoint.
Mercedes-Benz recommends a minimum treaddepth of
