ProblemPossible causes/consequences andPPSolutions
The engine does notstart. You cannot hearthe starter motor.
The on-board voltage is too low because the battery is too weak ordischarged.
XJump-start the vehicle (Ypage 282).
If the engine does not start despite attempts to jump-start it:
XConsult a qualified specialist workshop.
The starter motor was exposed to a thermal load that was too high.
XAllow the starter motor to cool down for approximately two minutes.
XTry to start the engine again.
If the engine still does not start:
XConsult a qualified specialist workshop.
The engine is not runningsmoothly and is misfir-ing.
There is a malfunction in the engine electronics or in a mechanicalcomponent of the engine management system.
XOnly depress the accelerator pedal slightly.Otherwise, non-combusted fuel may get into the catalytic converterand damage it.
XHave the cause rectified immediately at a qualified specialist work-shop.
The coolant temperaturegauge shows a valueabove 248 ‡ (120 †).The coolant warninglamp may also be on anda warning tone maysound.
The coolant level is too low. The coolant is too hot and the engine is nolonger being cooled sufficiently.
XStop as soon as possible and allow the engine and the coolant tocool down.
XCheck the coolant level (Ypage 263). Observe the warning notesas you do so and add coolant if necessary.
Notes on towing vehicles
The vehicle is not suitable for attaching tow barsystems, such as those used for flat towing ordinghy towing.
Attaching or using tow bar systems may result indamage to the vehicle.
When towing a vehicle with tow bar systems,safe driving characteristics cannot be guaran-teed for the towing vehicle or the towed vehicle.
The vehicle/trailer combination may swerve.
Observe the permissible towing methods(Ypage 287) and the notes on towing with bothaxles on the ground (Ypage 286).

Driving and parking
Z

cle with all wheels in full contact with theground.
4MATIC, together with ESP®, improves the trac-tion of your vehicle whenever a drive wheelspins due to insufficient grip.
If you fail to adapt your driving style, 4MATIC canneither reduce the risk of accident nor overridethe laws of physics. 4MATIC cannot takeaccount of road, weather and traffic conditions.4MATIC is only an aid. You are responsible forthe distance to the vehicle in front, for vehiclespeed, for braking in good time and for staying inyour lane.
If a drive wheel spins due to insufficient grip:
ROnly depress the accelerator pedal as far asnecessary when pulling away.
RAccelerate less when driving.
iIn wintry driving conditions, the maximumeffect of 4MATIC can only be achieved if youuse winter tires (M+S tires), with snow chainsif necessary.
DYNAMIC BODY CONTROL
General notes
DYNAMIC BODY CONTROL offers improveddriving comfort and continuously controls thecalibration of the dampers. The damping char-acteristics adapt to the current operating anddriving situation.
The damping is tuned individually to each wheeland depends on:
Ryour driving style, e.g. sporty
Rthe road surface conditions
Rthe drive program selected
The drive program can be set using theDYNAMIC SELECT button (Ypage 129).
Selecting Comfort mode
In theComfortdrive program, the driving char-acteristics of your vehicle are more comforta-ble. Therefore, select this drive program if youprefer a more comfortable driving style. Alsoselect theComfortdrive program when drivingfast on straight roads, e.g. on straight stretchesof highway.
XPress DYNAMIC SELECT button (Ypage 129)as many times as necessary until theCom-fortdrive program is selected.
Selecting Sport mode
The firmer setting of the suspension tuning intheSportdrive program ensures even bettercontact with the road. Select this drive programwhen employing a sporty driving style, e.g. onwinding country roads.
XPress DYNAMIC SELECT button (Ypage 129)as many times as necessary until theSportdrive program is selected.
Parking Assist PARKTRONIC
Important safety notes
Parking Assist PARKTRONIC is an electronicparking aid with ultrasound. It monitors the areaaround your vehicle using six sensors in thefront bumper and six sensors in the rearbumper. Parking Assist PARKTRONIC visuallyand audibly indicates the distance between yourvehicle and an object.
Parking Assist PARKTRONIC is only an aid. It isnot a replacement for your attention to yourimmediate surroundings. You are alwaysresponsible for safe maneuvering, parking andexiting a parking space. Make sure that thereare no persons, animals or objects in the maneu-vering area when you are maneuvering or park-ing.
!When parking, pay particular attention toobjects above or below the sensors, such asflower pots or trailer drawbars. Parking AssistPARKTRONIC does not detect such objectswhen they are in the immediate vicinity of thevehicle. You could damage the vehicle or theobjects.
The sensors may not detect snow and otherobjects that absorb ultrasonic waves.
Ultrasonic sources such as an automatic carwash, the compressed-air brakes of a truck ora pneumatic drill could cause Parking AssistPARKTRONIC to malfunction.
Parking Assist PARKTRONIC may not functioncorrectly on uneven terrain.

Driving an d parking

Parking tips:
ROn narrow roads, drive as close to the parkingspace as possible
RParking spaces that are littered or overgrownmight be identified or measured incorrectly
RParking spaces that are partially occupied bytrailer drawbars might not be identified assuch or be measured incorrectly
RSnowfall or heavy rain may lead to a parkingspace being measured inaccurately
RPay attention to the warning messages ofParking Assist PARKTRONIC during the park-ing procedure (Ypage 164).
RYou can intervene in the steering procedureto correct it at any time. Active Parking Assistwill then be canceled
RWhen transporting a load which protrudesfrom your vehicle, you should not use ActiveParking Assist
RNever use Active Parking Assist when snowchains are installed
RMake sure that the tire pressures are alwayscorrect. This has a direct influence on theparking characteristics of the vehicle.
Use Active Parking Assist for parking spaces:
Rthat are parallel or at right-angles to the direc-tion of travel
Ron straight roads, not bends
Ron the same level as the road, e.g. not on thepavement
Detecting parking spaces
Objects located above the detection range ofActive Parking Assist will not be detected whenthe parking space is measured. These are nottaken into account when the parking procedureis calculated, e.g. overhanging loads, truck over-hangs or loading ramps. Active Parking Assistmay therefore guide you into the parking spacetoo early.
Active Parking Assist does not support you park-ing in spaces at right angles to the direction oftravel if:
Rtwo parking spaces are located directly nextto one another
Rthe parking space is directly next to a lowobstacle such as a low curb
Ryou park forwards
Active Parking Assist does not support you park-ing in spaces that are parallel or at right anglesto the direction of travel if:
Rthe parking space is on a curb
Rthe system reads the parking space as beingblocked, for example by foliage or grass pav-ing blocks
Rthe area is too small for the vehicle to maneu-ver into
Rthe parking space is bordered by an obstacle,e.g. a tree, a post or a trailer
Further information about the detection range(Ypage 163).
GWARNING
If there are objects above the detection range:
Rthe Parking Package with rear view camera
may steer too early
Rthe vehicle may not stop in front of these
objects
This could cause a collision. There is a risk of
an accident.
If objects are located above the detection
range, stop and deactivate the Parking Pack-
age with rear view camera.

Permitted towing methods
Mercedes-Benz recommends transporting yourvehicle in the case of a breakdown, rather thantowing it away.
When towing away, use a towing rope or a tow-ing bar with both axles on the ground. Do not useany tow bar systems.
Transporting the vehicle
Vehicles with automatic transmission
!When the vehicle is loaded for transport, thefront and rear axles must be stationary and onthe same transportation vehicle. Positioningover the connection point of the transportvehicle is not permitted. The drive train mayotherwise be damaged.
All vehicles
!You may only secure the vehicle by thewheels, not by parts of the vehicle such asaxle or steering components. Otherwise, thevehicle could be damaged.
XTurn the SmartKey to positionHin the igni-tion lock (Ypage 123).
XShift the transmission to position\\.
As soon as the vehicle has been loaded:
XPrevent the vehicle from rolling away byapplying the electric parking brake.
XShift the transmission to position].
XTurn the SmartKey to positionZin the igni-tion lock and remove it.
XSecure the vehicle.
The towing eye can be used to pull the vehicleonto a trailer or transporter for transporting pur-poses.
Notes on 4MATIC vehicles
!Vehicles with 4MATIC must not be towedwith either the front or the rear axle raised, asdoing so will damage the transmission.
Vehicles with 4MATIC may only either be towedaway with both axles on the ground or be loadedup and transported.
If the vehicle's transmission, front, or rear axle isdamaged, have the vehicle transported on atruck or trailer.
In the event of damage to the electrical sys-tem:
If the battery is defective, the automatic trans-mission will be locked in position]. To shift theautomatic transmission to position\\, youmust provide power to the vehicle's on-boardelectrical system in the same way as when jump-starting (Ypage 282).
Have the vehicle transported on a transporter ortrailer.
Tow-starting (emergency engine
starting)
!Vehicles with automatic transmission mustnot be tow-started. You could otherwise dam-age the automatic transmission.
iYou can find information on "Jump-starting"under (Ypage 282).
Fuses
Important safety notes
GWARNING
If you manipulate or bridge a faulty fuse or if
you replace it with a fuse with a higher amper-
age, the electric cables could be overloaded.
This could result in a fire. There is a risk of an
accident and injury.
Always replace faulty fuses with the specified
new fuses having the correct amperage.
