If you select the reverse gear, Active Blind SpotAssist is not operational.
The brightness of the warning lamps is auto-matically adapted to the brightness of the sur-roundings.
When Active Blind Spot Assist is activated, grayradar waves propagating backward appear nextto the vehicle in the assistance display in themultifunction display. Above a speed of 20 mph(30 km/h), the color of the radar waves in theassistance display changes to greenD. ActiveBlind Spot Assist is then ready for use.
Collision warning from visual warning and
warning tone
If you switch on the turn signal to change lanesand a vehicle is detected in the side monitoringrange, you receive a visual warning and a warn-ing tone as a collision warning. You will thenhear a double warning tone and red warninglampCflashes. If the turn signal remains on,detected vehicles are indicated by the flashingof red warning lampC. No further warning tonesounds.
Course-correcting brake application
If Active Blind Spot Assist detects a risk of a lat-eral collision in the monitoring range, a course-correcting brake application is carried out. Thisis meant to assist you in avoiding a collision.
GWARNING
A course-correcting brake application cannot
always prevent a collision. There is a risk of an
accident.
Always steer, brake or accelerate yourself,
especially if Active Blind Spot Assist warns
you or makes a course-correcting brake appli-
cation. Always maintain a safe distance at the
sides.
If a course-correcting brake application occurs,red warning lampCflashes in the exterior mir-ror and a double warning tone sounds. In addi-tion, a display underlining the danger of a sidecollision appears in the multifunction display.
In very rare cases, the system may make aninappropriate brake application. A course-cor-recting brake application may be interrupted atany time by countersteering slightly or acceler-ating.
The course-correcting brake application is avail-able in the speed range between 20 mph(30 km/h) and 120 mph (200 km/h).
Either no braking application, or a course-cor-recting brake application adapted to the drivingsituation occurs if:
Rthere are vehicles or obstacles, e.g. crashbarriers, located on both sides of your vehicle.
Ra vehicle approaches you too closely at theside.
Ryou have adopted a sporty driving style withhigh cornering speeds.
Ryou clearly brake or accelerate.
Ra driving safety system intervenes, e.g. ESP®
or PRE-SAFE®Brake.
RESP®is switched off
Ra loss of tire pressure or a defective tire isdetected.

Active Lane Keeping Assist
General notes
Active Lane Keeping Assist monitors the area infront of your vehicle by means of multifunctioncameraCat the top of the windshield. Variousdifferent areas to the front, rear and side of yourvehicle are also monitored with the aid of theradar sensor system. Active Lane KeepingAssist detects lane markings on the road andcan warn you before you leave your lane unin-tentionally. If you do not react to the warning, alane-correcting application of the brakes canbring the vehicle back into the original lane.
This function is available in the range between40 mph and 120 mph (60 km/h and 200 km/h).
Important safety notes
If you fail to adapt your driving style, Active LaneKeeping Assist can neither reduce the risk of anaccident nor override the laws of physics. ActiveLane Keeping Assist cannot take account ofroad and weather conditions. It may not recog-nize traffic situations. Active Lane KeepingAssist is only an aid. You are responsible for thedistance to the vehicle in front, for vehiclespeed, for braking in good time and for staying inyour lane.
Active Lane Keeping Assist cannot continuouslykeep your vehicle in its lane.
GWARNING
Active Lane Keeping Assist cannot always
clearly detect lane markings.
In such cases, Active Lane Keeping Assist
can:
Rgive an unnecessary warning and then
make a course-correcting brake application
Rneither give a warning nor intervene
There is a risk of an accident.
Always pay particular attention to the traffic
situation and keep within the lane, especially
if Active Lane Keeping Assist alerts you. Ter-
minate the intervention in a non-critical driv-
ing situation.
The system may be impaired or may not functionif:
Rthere is poor visibility, e.g. due to insufficientillumination of the road, or due to snow, rain,fog or heavy spray
Rthere is glare, e.g. from oncoming traffic, thesun or reflection from other vehicles (e.g. ifthe road surface is wet)
Rthe windshield is dirty, fogged up, damaged orcovered, for instance by a sticker, in the vicin-ity of the camera
Rthe radar sensors in the front or rear bumpersor the radiator trim are dirty, e.g. obscured bysnow
Rthere are no or several unclear lane markingsfor one lane, e.g. roadworks
Rthe lane markings are worn away, dark or cov-ered up, e.g. by dirt or snow
Rthe distance to the vehicle in front is too shortand thus the lane markings cannot be detec-ted
Rthe lane markings change quickly, e.g. lanesbranch off, cross one another or merge
Rthe road is narrow and winding
Rthere are highly variable shade conditions onthe roadway
If no vehicle is detected in the adjacent lane andbroken lane markings are detected, no lane-cor-recting brake application is made.
Warning vibration in the steering wheel
A warning may be given if a front wheel passesover a lane marking. It will warn you by means ofintermittent vibration in the steering wheel forup to 1.5 seconds.

Towing a trailer
Important safety notes
GWARNING
Installing an unsuitable ball coupling may
result in overloading of the trailer tow hitch
and the rear axle. This applies especially if the
ball coupling in question is longer or angled
differently. This could seriously impair the
driving characteristics and the trailer can
come loose. There is a risk of an accident.
You should only ever install a ball coupling
that has the permissible dimensions and that
is designed to meet your trailer-towing
requirements. Do not modify the ball coupling
or the trailer tow hitch.
You will find the values approved by the manu-facturer on the vehicle identification plates andthose for the towing vehicle under "Technicaldata" (Ypage 364).
GWARNING
When the vehicle/trailer combination begins
to lurch, you could lose control of it. The vehi-
cle/trailer combination could even rollover.
There is a risk of an accident.
On no account should you attempt to
straighten up the vehicle/trailer combination
by increasing the speed. Reduce vehicle
speed and do not countersteer. Apply the
brake as necessary.
!If you have a trailer tow hitch retrofitted,changes to the engine cooling system may benecessary, depending on the vehicle type.
If you have a trailer tow hitch retrofitted,observe the anchorage points on the chassisframe.
The installation of a trailer tow hitch is only per-missible if a towing weight is specified in yourvehicle documents. If this is not the case, thenthe vehicle is not approved for the towing of atrailer.

General notes
The multimedia system section in this Opera-tor's Manual describes the basic principles foroperation. More information can be found in theDigital Operator's Manual.
Important safety notes
GWARNING
If you operate information systems and com-
munication equipment integrated in the vehi-
cle when driving, you may be distracted from
the traffic situation. You could also lose con-
trol of the vehicle. There is a risk of an acci-
dent.
Only operate this equipment when the traffic
situation permits. If you are not sure that this
is possible, park the vehicle paying attention
to traffic conditions and operate the equip-
ment when the vehicle is stationary.
You must observe the legal requirements for thecountry in which you are currently driving whenoperating the multimedia system.
The multimedia system calculates the route tothe destination without taking the following intoaccount, for example:
Rtraffic lights
Rstop and yield signs
Rparking or stopping restrictions
Rroad narrowing
Rother road and traffic rules and regulations
The multimedia system may give incorrect nav-igation recommendations if the actual street/traffic situation does not correspond with thedigital map's data.
For example:
Ra diverted route
Rthe road layout or the direction of a one-waystreet has been changed
For this reason, you must always observe roadand traffic rules and regulations during yourjourney. Road and traffic rules and regulationsalways have priority over multimedia systemdriving recommendations.
Navigation announcements are intended todirect you while driving without diverting yourattention from the road and driving.
Please always use this feature instead of con-sulting the map display for directions. Lookingat the icons or map display can distract you fromtraffic conditions and driving, and increase therisk of an accident.
This equipment complies with FCC radiationexposure limits set forth for uncontrolled equip-ment and meets the FCC radio frequency (RF)Exposure Guidelines in Supplement C to OET65.
This equipment has very low levels of RF energythat is deemed to comply without maximumpermissive exposure evaluation (MPE). How-ever, it is recommended to install it at a distanceof at least 8 inches (approx. 20 cm) between theradiation source and a person's body (notincluding limbs such as hands, wrists, feet andlegs).
GWARNING
Modifications to electronic components, their
software as well as wiring can impair their
function and/or the function of other net-
worked components. In particular, systems
relevant to safety could also be affected. As a
result, these may no longer function as inten-
ded and/or jeopardize the operating 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.

Maximum tire pressures
CExample: maximum permissible tire pres-sure
Never exceed the maximum permissible tireinflation pressure. Always observe the recom-mended tire pressure for your vehicle whenadjusting the tire pressure (Ypage 333).
iThe actual values for tires are vehicle-spe-cific and may deviate from the values in theillustration.
Checking the tire pressures
Important safety notes
Observe the notes on tire pressure(Ypage 333).
Information on air pressure for the tires on yourvehicle can be found:
Ron the vehicle's Tire and Loading Informationplacard on the B-pillar
Rin the tire pressure table in the fuel filler flap(Ypage 333)
Rin the "Tire pressure" section
Checking tire pressures manually
To determine and set the correct tire pressure,proceed as follows:
XRemove the valve cap of the tire that is to bechecked.
XPress the tire pressure gauge securely ontothe valve.
XRead the tire pressure and compare it to therecommended value on the Tire and LoadingInformation placard or the tire pressure table(Ypage 333).
XIf the tire pressure is too low, increase the tirepressure to the recommended value.
XIf the tire pressure is too high, release air. Todo so, press down the metal pin in the valve,using the tip of a pen for example. Then checkthe tire pressure again using the tire pressurechecker.
XScrew the valve cap onto the valve.
XRepeat these steps for the other tires.
Tire pressure loss warning system
General notes
While the vehicle is in motion, the tire pressureloss warning system monitors the set tire pres-sure using the rotational speed of the wheels.This enables the system to detect significantpressure loss in a tire. If the speed of rotation ofa wheel changes as a result of a loss of pressure,a corresponding warning message will appear inthe multifunction display.
You can recognize the tire pressure loss warningby theRun Flat Indicator ActiveRun Flat Indicator ActivePressPress'OK' to Restart'OK' to Restartmessage which appears intheServiceServicemenu of the multifunction display.Information on the message display can befound in the "Restarting the tire pressure losswarning system" section (Ypage 337).
Important safety notes
The tire pressure warning system does not warnyou of an incorrectly set tire pressure. Observethe notes on the recommended tire pressure(Ypage 333).
The tire pressure loss warning does not replacethe need to regularly check the tire pressure. Aneven loss of pressure on several tires at thesame time cannot be detected by the tire pres-sure loss warning system.
The tire pressure monitor is not able to warn youof a sudden loss of pressure, e.g. if the tire ispenetrated by a foreign object. In the event of asudden loss of pressure, bring the vehicle to ahalt by braking carefully. Avoid abrupt steeringmovements.
The function of the tire pressure loss warningsystem is limited or delayed if:
Rsnow chains are mounted on your vehicle'stires.
Rroad conditions are wintry.

Wheels and tires

must be positioned vertically, directly under
the jacking point of the vehicle.
!Only position the jack at the appropriatejacking point of the vehicle. Otherwise, youcould damage the vehicle.
Observe the following when raising the vehi-cle:
RTo raise the vehicle, only use the vehicle-spe-cific jack that has been tested and approvedby Mercedes-Benz. If used incorrectly, thejack could tip over with the vehicle raised.
RThe jack is designed only to raise and hold thevehicle for a short time while a wheel is beingchanged. It must not be used for performingmaintenance work under the vehicle.
RAvoid changing the wheel on uphill and down-hill slopes.
RBefore raising the vehicle, secure it from roll-ing away by applying the parking brake andinserting wheel chocks. Do not disengage theparking brake while the vehicle is raised.
RThe jack must be placed on a firm, flat andnon-slip surface. On a loose surface, a large,flat, load-bearing underlay must be used. On aslippery surface, a non-slip underlay must beused, e.g. rubber mats.
RDo not use wooden blocks or similar objectsas a jack underlay. Otherwise, the jack will notbe able to achieve its load-bearing capacitydue to the restricted height.
RMake sure that the distance between theunderside of the tires and the ground does notexceed 1.2 in (3 cm).
RDo not place your hands or feet under theraised vehicle.
RDo not lie under the vehicle.
RDo not start the engine when the vehicle israised.
RNever open or close a door or the tailgatewhen the vehicle is raised.
RMake sure that no persons are present in thevehicle when the vehicle is raised.
XUsing lug wrenchC, loosen the bolts on thewheel you wish to change by about one fullturn. Do not unscrew the bolts completely.
The jacking points are located just behind thefront wheel housings and just in front of the rearwheel housings (arrows).
XTake the ratchet wrench out of the tire-chang-ing tool kit and place it on the hexagon nut ofthe jack so that the lettersAUFare visible.
XPosition jack
