Important safety notes
GWARNING
If you do not have the prescribed service/
maintenance work or any required repairs
carried out, this can result in malfunctions
or system failures. There is a risk of an acci-
dent.
Always have the prescribed service/mainte-
nance work as well as any required repairs
carried out at a qualified specialist work-
shop.
GWARNING
Flammable material such as leaves, grass or
twigs may ignite if they come into contact
with hot parts of the exhaust system. There
is a risk of fire.
When driving on an unpaved road or off-
road, check the vehicle underside regularly.
In particular, remove trapped plant parts or
other flammable material. Contact a quali-
fied specialist workshop immediately if dam-
age is detected.
GWARNING
Modifications to electronic components,
their software as well as wiring can impair
their function and/or the function of other
networked components. In particular, sys-
tems relevant to safety could also be affec-
ted. As a result, these may no longer func-
tion as intended and/or jeopardize the oper-
ating safety of the vehicle. There is an
increased risk of an accident and injury.
Never tamper with the wiring as well as elec-
tronic components or their software. You
should have all work to electrical and elec-
tronic equipment carried out at a qualified
specialist workshop.
!There is a risk of damage to the vehicle if:
Rthe vehicle becomes stuck, e.g. on a highcurb or an unpaved road
Ryou drive too fast over an obstacle, e.g. acurb, a speed bump or a pothole in theroad
Ra heavy object strikes the underbody orparts of the chassis
In situations like this, the body, the under-body, chassis parts, wheels or tires could bedamaged without the damage being visible.Components damaged in this way can unex-pectedly fail or, in the case of an accident,no longer withstand the loads they aredesigned to.
If the underbody paneling is damaged, com-bustible materials such as leaves, grass ortwigs can gather between the underbodyand the underbody paneling. If these materi-als come in contact with hot parts of theexhaust system, they can catch fire.
In such situations, have the vehicle checkedand repaired immediately at a qualified spe-cialist workshop. If on continuing your jour-ney you notice that driving safety isimpaired, pull over and stop the vehicleimmediately, paying attention to road andtraffic conditions. In such cases, consult aqualified specialist workshop.

Driving safety systems
Overview of driving safety systems
In this section, you will find information aboutthe following driving safety systems:
RABS (Anti-lockBrakingSystem)(Ypage 60)
RBAS (BrakeAssistSystem) (Ypage 61)
RBrake Assist with cross-traffic function(Ypage 61)
RActive Brake Assist (Ypage 63)
RAdaptive brake lights (Ypage 65)
RESP®(ElectronicStabilityProgram)(Ypage 65)
REBD (ElectronicBrake forceDistribution)(Ypage 69)
RADAPTIVE BRAKE (Ypage 70)
RActive Brake Assist with cross-traffic func-tion (Ypage 70)
RSTEER CONTROL (Ypage 72)
Important safety notes
If you fail to adapt your driving style or if youare inattentive, the driving safety systems canneither reduce the risk of an accident noroverride the laws of physics. Driving safetysystems are merely aids designed to assistdriving.
You are responsible for maintaining the dis-tance to the vehicle in front, for vehicle speed,for braking in good time, and for staying inlane. Always adapt your driving style to suitthe prevailing road and weather conditions andmaintain a safe distance from the vehicle infront. Drive carefully.
The driving safety systems described onlywork as effectively as possible when there isadequate contact between the tires and theroad surface. Pay particular attention to theinformation regarding tires, recommendedminimum tire tread depths etc. in the "Wheelsand tires" section (Ypage 293).
In wintry driving conditions, always use wintertires (M+S tires) and if necessary, snow
chains. Only in this way will the driving safetysystems described in this section work aseffectively as possible.
ABS (Anti-lock Braking System)
General information
ABS regulates brake pressure in such a waythat the wheels do not lock when you brake.This allows you to continue steering the vehi-cle when braking.
The%ABS warning lamp in the instrumentcluster lights up when the ignition is switchedon. It goes out when the engine is running.
ABS works from a speed of about 5 mph(8 km/h), regardless of road-surface condi-tions. ABS works on slippery surfaces, evenwhen you only brake gently.
Important safety notes
iObserve the "Important safety notes" sec-tion (Ypage 60).
GWARNING
If ABS is malfunctioning, the wheels could
lock when braking. The steerability and
braking characteristics would be severely
affected. There is an increased danger of
skidding and accidents.
Drive on carefully. Have ABS checked imme-
diately at a qualified specialist workshop.
When ABS is malfunctioning, other systems,including driving safety systems, will alsobecome inoperative. Observe the informationon the ABS warning lamp (Ypage 236) anddisplay messages which may be shown in theinstrument cluster (Ypage 206).
Brakes
XIf ABS intervenes:continue to depress thebrake pedal vigorously until the braking sit-uation is over.
XTo make a full brake application:depressthe brake pedal with full force.
If ABS intervenes when braking, you will feel apulsing in the brake pedal.
60Driving safety systems
Safety

Adaptive Brake Assist provides braking assis-tance in hazardous situations at speeds above4 mph (7 km/h). It uses radar sensor technol-ogy to assess the traffic situation.
Up to a speed of approximately 155 mph(250 km/h), Adaptive Brake Assist is capableof reacting to moving objects that havealready been detected as such at least onceover the period of observation.
Up to a speed of approximately 44 mph(70 km/h), Adaptive Brake Assist reacts tostationary obstacles.
If Adaptive Brake Assist demands particularlyhigh braking force, preventative passenger
protection measures (PRE-SAFE®) are activa-ted simultaneously (Ypage 55).
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 vehi-cle
Adaptive Brake Assist is then deactivated.
Important safety notes
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
situation and be ready to brake. Terminate
the intervention in a non-critical driving sit-
uation.
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
situation and be ready to brake.
Always adapt your speed to suit the prevail-
ing road and traffic conditions.
Due to the nature of the system, particularlycomplicated but non-critical driving conditionsmay also cause Adaptive Brake Assist to inter-vene.
If Adaptive Brake Assist is not available due toa malfunction in the radar sensor system, thebrake system remains available with full brakeboosting effect and BAS.
Adaptive brake lights
iObserve the "Important safety notes" sec-tion (Ypage 60).
If you brake sharply from a speed of more than50 km/h or if braking is assisted by BAS orBrake Assist with Cross-Traffic Assist, thebrake lamps flash rapidly. In this way, traffictraveling behind you is warned in an evenmore noticeable manner.
If you brake sharply from a speed of more than70 km/h to a standstill, the hazard warninglamps are activated automatically. If thebrakes are applied again, the brake lamps lightup continuously. The hazard warning lampsswitch off automatically if you travel fasterthan 10 km/h. You can also switch off thehazard warning lamps using the hazard warn-ing button (Ypage 111).
ESP®(Electronic Stability Program)
General notes
iObserve the "Important safety notes" sec-tion (Ypage 60).
ESP®monitors driving stability and traction,i.e. power transmission between the tires andthe road surface.
If ESP®detects that the vehicle is deviatingfrom the direction desired by the driver, one ormore wheels are braked to stabilize the vehi-cle. The engine output is also modified to keep

the vehicle on the desired course within physi-
cal limits. ESP®assists the driver when pulling
away on wet or slippery roads. ESP®can alsostabilize the vehicle during braking.
ETS (Electronic Traction System)
iObserve the "Important safety notes" sec-tion (Ypage 60).
ETS traction control is part of ESP®.
ETS brakes the drive wheels individually if theyspin. This enables you to pull away and accel-erate on slippery surfaces, for example if theroad surface is slippery on one side. In addi-tion, more drive torque is transferred to thewheel or wheels with traction.
ETS remains active when you deactivate ESP®.
iMercedes-AMG vehicles:your vehiclemay be equipped with 20-inch tires on therear axle. After changing to 19 inch wheels,ETS may intervene noticeably earlier duringthe first few kilometers. After approximately10 km ETS will function as usual again.Information on the dimensions and types ofwheels and tires for your vehicle can befound in the "Wheel/tire combinations" sec-tion (Ypage 318).
Important safety notes
GWARNING
If ESP®is malfunctioning it will not provide
any vehicle stabilization. There is an
increased risk of skidding or of an accident.
Exercise caution when continuing to drive.
Have ESP®checked at a qualified specialist
workshop.
When towing the vehicle with the rear axle
raised, observe the notes on ESP®
(Ypage 290).

Driving tips
General notes
Important safety notes
GWARNING
If you switch off the ignition while driving,
safety-relevant functions are only available
with limitations, or not at all. This could
affect, for example, the power steering and
the brake boosting effect. You will require
considerably more effort to steer and brake.
There is a risk of an accident.
Do not switch off the ignition while driving.
GWARNING
If you operate mobile communication equip-
ment when driving, you may be distracted
from the traffic situation. You could also
lose control of the vehicle. There is a risk of
an accident.
Only operate this equipment when the vehi-
cle is stationary.
Observe the legal requirements for the countryin which you are driving. Some jurisdictionsprohibit the driver from using a mobile phonewhile driving a vehicle.
If you make a call while driving, always usehands-free mode. Only operate the telephonewhen the traffic situation permits. If you areunsure, pull over to a safe location and stopbefore operating the telephone.
Bear in mind that at a speed of only 30 mph(approximately 50 km/h), the vehicle covers adistance of 44 ft (approximately 14 m) persecond.
Drive sensibly – save fuel
Observe the following tips to save fuel:
RThe tires should always be inflated to therecommended tire pressure.
RRemove unnecessary loads.
RWarm up the engine at low engine speeds.
RAvoid frequent acceleration or braking.
RObserve the service intervals in the Mainte-nance Booklet or in the service interval dis-play. Have all the maintenance work carriedin accordance with Daimler AG regulations.
Fuel consumption also increases when drivingin cold weather, in stop-start traffic and in hillyterrain.
Drinking and driving
GWARNING
Drinking and driving and/or taking drugs
and driving are very dangerous combina-
tions. Even a small amount of alcohol or
drugs can affect your reflexes, perceptions
and judgment.
The possibility of a serious or even fatal
accident is greatly increased when you drink
or take drugs and drive.
Do not drink or take drugs and drive or allow
anyone to drive who has been drinking or
taking drugs.

New and replaced brake pads and discs onlyreach their optimum braking effect after sev-eral hundred kilometers of driving. Compen-sate for this by applying greater force to thebrake pedal. Keep this in mind, and adapt yourdriving and braking accordingly during thisbreak-in period.
Excessive heavy braking results in correspond-ingly high brake wear. Observe the brake sys-tem warning lamp in the instrument clusterand note any brake status messages in themultifunction display. Especially for high per-formance driving, it is important to maintainand have the brake system checked regularly.
Driving on wet roads
Hydroplaning
If water has accumulated to a certain depth onthe road surface, there is a danger of hydro-planing occurring.
For this reason, in the event of heavy rain or inconditions in which hydroplaning may occur,you must drive in the following manner:
Rlower your speed
Ravoid ruts
Ravoid sudden steering movements
Rbrake carefully
Driving on flooded roads
!Do not drive through flooded areas. Checkthe depth of any water before drivingthrough it. Drive slowly through standingwater. Otherwise, water could enter thevehicle interior or engine compartment. Itcan then damage the engine's or automatictransmission's electronic components. Itcan also be sucked in by the engine's airintake connection and cause engine dam-age.
Winter driving
GWARNING
If you shift down on a slippery road surface
in an attempt to increase the engine's brak-
ing effect, the drive wheels could lose their
grip. There is an increased danger of skid-
ding and accidents.
Do not shift down for additional engine brak-
ing on a slippery road surface.
GDANGER
If the exhaust pipe is blocked or adequate
ventilation is not possible, poisonous gases
such as carbon monoxide (CO) may enter
the vehicle. This is the case, e.g. if the vehi-
cle becomes trapped in snow. There is a risk
of fatal injury.
If you leave the engine or the auxiliary heat-
ing running, make sure the exhaust pipe and
area around the vehicle are clear of snow.
To ensure an adequate supply of fresh air,
open a window on the side of the vehicle
that is not facing into the wind.
Have your vehicle winter-proofed at a qualifiedspecialist workshop at the onset of winter.
Drive particularly carefully on slippery roadsurfaces. Avoid sudden acceleration, steeringand braking maneuvers. Do not use cruisecontrol.
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 deviceand is 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, especiallyin wooded areas or on bridges. The vehiclecould skid if you fail to adapt your drivingstyle. Always adapt your driving style and driveat a speed to suit the prevailing weather condi-tions.
You should pay special attention to road con-ditions when temperatures are around freezingpoint.
