The data cannot be used to trace the vehicle'smovements.
When your vehicle is serviced, technical infor-mation can be read from the event data mem-ory and malfunction data memory.
Services include, for example:
Rrepair services
Rservice processes
Rwarranties
Rquality assurance
The vehicle is read out by employees of theservice network (including the manufacturer)using special diagnostic testers. More detailedinformation is obtained from it, if required.
After a malfunction has been rectified, theinformation is deleted from the malfunctionmemory or is continually overwritten.
When operating the vehicle, situations areconceivable in which this technical data, inconnection with other information (if neces-sary, under consultation with an authorizedexpert), could be traced to a person.
Examples include:
Raccident reports
Rdamage to the vehicle
Rwitness statements
Further additional functions that have beencontractually agreed upon with the customerallow certain vehicle data to be conveyed bythe vehicle as well. The additional functionsinclude, for example, vehicle location in caseof an emergency.
COMAND/Mercedes me connect
(Canada: TELEAID)
If the vehicle is equipped with COMAND orMercedes me connect, additional data aboutthe vehicle's operation, the use of the vehiclein certain situations, and the location of thevehicle is compiled through COMAND or theMercedes me connect system.
For additional information, please refer to theCOMAND User Manual or Digital Operator'sManual and/or the Mercedes me connectTerms and Conditions.
Event data recorders
USA only:
This vehicle is equipped with an event datarecorder (EDR). This vehicle is equipped withan event data recorder (EDR). The main pur-pose of an EDR is to record, in certain crash ornear crash-like situations, such as an air bagdeployment or hitting a road obstacle, datathat will assist in understanding how a vehi-cle's systems performed. The EDR is designedto record data relating to vehicle dynamicsand safety systems for a short period of time,typically 30 seconds or less.
The EDR in this vehicle is designed to recordsuch data as:
RHow various systems in your vehicle wereoperating
RWhether or not the driver and passengersafety belts were buckled/fastened
RHow far (if at all) the driver was depressingthe accelerator and/or brake pedal; and,
RHow fast the vehicle was traveling
These data can help provide a better under-standing of the circumstances in whichcrashes and injuries occur. NOTE: EDR dataare recorded by your vehicle only if a non-triv-ial crash situation occurs; no data are recor-ded by the EDR under normal driving condi-tions and no personal data (e.g. name, gender,age and crash location) are recorded. How-ever, other parties, such as law enforcementcould combine the EDR data with the type ofpersonally identifying data routinely acquiredduring a crash investigation.
Access to the vehicle and/or the EDR is nee-ded to read data that is recorded by an EDR,and special equipment is required. In additionto the vehicle manufacturer, other parties thathave the special equipment, such as lawenforcement, can read the information byaccessing the vehicle or the EDR.
EDR data may be used in civil and criminalmatters as a tool in accident reconstruction,accident claims and vehicle safety. Since theCrash Data Retrieval CDR tool that is used toextract data from the EDR is commercially

Side impact air bags
GWARNING
Unsuitable seat covers can obstruct or pre-
vent deployment of the air bags integrated
into the seats. Consequently, the air bags
cannot protect vehicle occupants as they
are designed to do. In addition, the opera-
tion of the occupant classification system
(OCS) could be adversely affected. This
poses an increased risk of injury or even
fatal injury.
You should only use seat covers that have
been approved for the respective seat by
Mercedes-Benz.
Front side impact air bagsCand rear sideimpact air bagsDdeploy next to the outerbolster of the seat backrest.
When deployed, the side impact air bag offersadditional thorax protection. It also offersadditional pelvis protection for occupants inthe front seats. However, it does not protectthe:
Rhead
Rneck
Rarms
If the restraint system control unit detects aside impact, the side impact air bag isdeployed on the side on which the impactoccurs.
The side impact air bag on the front passengerside deploys under the following conditions:
Rthe OCS system detects that the frontpassenger seat is occupied or
Rthe seat belt buckle tongue is engaged inthe belt buckle of the front passenger seat
If the belt tongue is engaged in the beltbuckle, the side impact air bag on the frontpassenger side deploys if an appropriate acci-dent situation occurs. In this case, deploymentis independent of whether the front passengerseat is occupied or not.

Window curtain air bags
Window curtain air bagsCare integrated intothe side of the roof frame and deployed in thearea from the A-pillar to the C-pillar.
When deployed, the window curtain air bagenhances the level of protection for the head.However, it does not protect the chest orarms.
If the restraint system control unit detects aside impact, the window curtain air bag isdeployed on the side on which the impactoccurs.
If the system determines that they can offeradditional protection to that provided by theseat belt, a window curtain air bag may bedeployed in other accident situations(Ypage 51).
Occupant Classification System
(OCS)
Introduction
The Occupant Classification System (OCS) cat-egorizes the person in the front-passengerseat. Depending on that result, the front-passenger front air bag and front-passengerknee bag are either enabled or deactivated.
The system does not deactivate:
Rthe side impact air bag
Rthe window curtain air bag
Rthe Emergency Tensioning Devices
Requirements
To be classified correctly, the front passengermust sit:
Rwith the seat belt fastened correctly
Rin an almost upright position with their backagainst the seat backrest
Rwith their feet resting on the floor, if possi-ble
If the front passenger does not observe theseconditions, OCS may produce a false classifi-cation, e.g. because the front passenger:
Rtransfers their weight by supporting them-selves on a vehicle armrest
Rsits in such a way that their weight is raisedfrom the seat cushion
If it is absolutely necessary to install a childrestraint system on the front-passenger seat,be sure to observe the correct positioning ofthe child restraint system. Never place objectsunder or behind the child restraint system, e.g.a cushion. The entire base of the childrestraint system must always rest on the seatcushion of the front-passenger seat. The back-rest of the forward-facing child restraint sys-tem must lie as flat as possible against thebackrest of the front-passenger seat.
The child restraint system must not touch theroof or be subjected to a load by the headrestraint. Adjust the angle of the seat backrestand the head restraint position accordingly.
Only then can OCS be guaranteed to functioncorrectly. Always observe the child restraintsystem manufacturer's installation and operat-ing instructions.

Problems with the Occupant Classification System (OCS)
Be sure to observe the notes on "System self-test" (Ypage 50).
ProblemPossible causes/consequences andPPSolutions
The PASSENGER AIRBAG OFF indicator lamplights up and remainslit, even though thefront-passenger seat isoccupied by an adult ora person of a staturecorresponding to that ofan adult.
The classification of the person on the front-passenger seat is incor-rect.
XMake sure the conditions for a correct classification of the per-son on the front-passenger seat are met (Ypage 47).
XIf the PASSENGER AIR BAG OFF indicator lamp remains lit, thefront-passenger seat may not be used.
XHave OCS checked as soon as possible at an authorizedMercedes-Benz Center.
The PASSENGER AIRBAG OFF indicator lampdoes not light upand/or does not stayon.
The front-passengerseat is:
Runoccupied
Roccupied by theweight of a child upto twelve months oldin a child restraintsystem
OCS is malfunctioning.
XMake sure there is nothing between the seat cushion and thechild seat.
XMake sure that the entire base of the child restraint system restson the seat cushion of the front-passenger seat. The backrest ofthe forward-facing child restraint system must lie as flat as possi-ble against the backrest of the front passenger seat. If necessary,adjust the position of the front-passenger seat.
XMake sure that the seat cushion length is fully retracted.
XWhen installing the child restraint system, make sure that theseat belt is tight. Do not pull the seat belt tight using the front-passenger seat adjustment. This could result in the seat belt andthe child restraint system being pulled too tightly.
XCheck for correct installation of the child restraint system.
Make sure that the head restraint does not apply a load to thechild restraint system. If necessary, adjust the head restraintaccordingly.
XMake sure that no objects are applying additional weight onto theseat.
XIf the PASSENGER AIR BAG OFF indicator lamp remains offand/or the PASSENGER AIR BAG ON indicator lamp lights up, donot install a child restraint system on the front-passenger seat. Itis recommended that you install the child restraint system on asuitable rear seat.
XHave OCS checked as soon as possible at an authorizedMercedes-Benz Center.

The air bag parts are hot after an air bag has
been deployed. There is a risk of injury.
Do not touch the air bag parts. Have a
deployed air bag replaced at a qualified spe-
cialist workshop as soon as possible.

The rate of vehicle deceleration or accelera-tion and the direction of the force are essen-tially determined by:
Rthe distribution of forces during the collision
Rthe collision angle
Rthe deformation characteristics of the vehi-cle
Rthe characteristics of the object with whichthe vehicle has collided
Factors which can only be seen and measuredafter a collision has occurred do not play adecisive role in the deployment of an air bag.Nor do they provide an indication of air bagdeployment.
The vehicle can be deformed considerably,without an air bag being deployed. This is thecase if only parts which are relatively easilydeformed are affected and the rate of deceler-ation is not high. Conversely, air bags may bedeployed even though the vehicle suffers onlyminor deformation. This is the case if, forexample, very rigid vehicle parts such as longi-tudinal body members are hit, and sufficientdeceleration occurs as a result.
If the restraint system control unit detects aside impact or if the vehicle rolls over, theapplicable components of the restraint systemare deployed independently of each otherdepending on the apparent type of accident.

iNot all air bags are deployed in an acci-dent. The different air bag systems workindependently of each other.
How the air bag system works is determinedby the severity of the accident detected,especially the vehicle deceleration or accel-eration and the apparent type of accident:
RHead-on collision
RSide impact
RRollover
Automatic measures after an acci-
dent
Immediately after an accident, the followingmeasures are implemented, depending on thetype and severity of the impact:
Rthe hazard warning lamps are switched on
Rthe emergency lighting is activated
Rthe vehicle doors are unlocked
Rthe front side windows are lowered
Rthe engine is switched off and the fuel sup-ply is cut off

Children in the vehicle
Important safety notes
Accident statistics show that children securedin the rear seats are safer than childrensecured in the front-passenger seat. For thisreason, Mercedes-Benz strongly advises thatyou install a child restraint system on a rearseat. Children are generally better protectedthere.
If a child younger than twelve years old andunder 5 ft (1.50 m) in height is traveling in thevehicle:
Ralways secure the child in a child restraintsystem suitable for Mercedes-Benz vehicles.The child restraint system must be appropri-ate to the age, weight and size of the child.
Rbe sure to observe the instructions andsafety notes in this section in addition to the

Overview of climate control systems
General notes
Observe the settings recommended on the fol-lowing pages. The windows could otherwisefog up.
To prevent the windows from fogging up:
Rswitch off climate control only briefly
Rswitch on air-recirculation mode only briefly
Rswitch on the cooling with air dehumidifica-tion function
Rswitch on the defrost windshield functionbriefly, if required
The air-conditioning system or dual-zone auto-matic climate control regulates the tempera-ture and the humidity of the vehicle interiorand filters undesirable substances from theair.
The air-conditioning system or dual-zone auto-matic climate control can only be operatedwhen the engine is running. Optimum opera-tion is only achieved with the side windowsand panorama roof with power tilt/slidingpanel closed.
If you start the engine using your smartphone,the last selected climate control setting isreactivated (Ypage 84).
The residual heat function can only be activa-ted or deactivated with the ignition switchedoff (Ypage 122).
Always keep the ventilation flaps behind theside trim panel in the cargo compartmentclear (Ypage 108). Otherwise the vehicle willnot be ventilated correctly.
iVentilate the vehicle for a brief period dur-ing warm weather, e.g. using the conveni-ence opening feature (Ypage 84). This willspeed up the cooling process and thedesired interior temperature will be reachedmore quickly.
iThe integrated filter filters out most parti-cles of dust and soot and completely filtersout pollen. It also reduces gaseous pollu-tants and odors. A clogged filter reduces theamount of air supplied to the vehicle inte-rior. For this reason, you should alwaysobserve the interval for replacing the filter,which is specified in the Maintenance Book-let. As it depends on environmental condi-tions, e.g. heavy air pollution, the intervalmay be shorter than stated in the Mainte-nance Booklet.
iIt is possible that under certain circum-stances the residual heat function may beactivated automatically an hour after theSmartKey has been removed in order to drythe automatic climate control. The vehicle isthen ventilated for 30 minutes.
