ProblemPossible causes/consequences andPPSolutions
The engine is not run-ning smoothly and ismisfiring.
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 con-verter and damage it.
XHave the cause rectified immediately at a qualified specialistworkshop.
The coolant tempera-ture display shows avalue above 248 ‡(120 †). The coolantwarning lamp may alsobe on and a warningtone may sound.
The coolant level is too low. The coolant is too hot and the engine isno longer being cooled sufficiently.
XStop as soon as possible and allow the engine and the coolant tocool down.
XCheck the coolant level (Ypage 267). Observe the warning notesas you do so and add coolant if necessary.
If the coolant level is correct, the engine radiator fan may be faulty.The coolant is too hot and the engine is no longer being cooled suf-ficiently.
XAt coolant temperatures below 248 ‡ (120 †), drive to the near-est qualified specialist workshop.
XAvoid heavy loads on the engine as you do so, e.g. driving inmountainous terrain and stop-and-go traffic.
Notes on towing vehicles
The vehicle is not suitable for attaching towbar systems, such as those used for flat tow-ing or dinghy towing.
Attaching or using tow bar systems may resultin damage 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 vehi-cle.
The vehicle/vehicle combination may swerve.
Observe the permissible towing methods(Ypage 289) and the notes on towing withboth axles on the ground (Ypage 289).

Do not shift the transmission toDwhile driving. The automatictransmission could otherwise bedamaged.
No power is transmitted from theengine to the drive wheels.
Releasing the brake pedal will allowyou to move the vehicle freely, e.g.to push it or tow it.
If ESP®is deactivated or faulty: shiftthe transmission to positionDifthe vehicle is in danger of skidding,e.g. on icy roads.
!Coasting in neutral\\maycause damage to the drive train.
:Drive
The automatic transmissionchanges gear automatically. Allforward gears are available.
Driving tips
Changing gear
The automatic transmission shifts through theindividual gears automatically when it is intransmission position[. This automatic gearshifting behavior is determined by:
Rthe selected drive program
Rthe position of the accelerator pedal
Rthe road speed
Accelerator pedal position
Your style of driving influences how the auto-matic transmission shifts gear:
Rlittle throttle: early upshifts
Rmore throttle: late upshifts
Kickdown
Use kickdown for maximum acceleration.
XDepress the accelerator pedal beyond thepressure point.The automatic transmission shifts to a lowergear depending on the engine speed.
XEase off the accelerator pedal once thedesired speed is reached.The automatic transmission shifts back up.

Manual gear shifting
General notes
You can change gear yourself using the steer-ing wheel paddle shifters. The transmissionmust be in position[to do this.
Depending on which steering wheel paddleshifter is pulled, the automatic transmissionimmediately shifts into the next gear down orup, if permitted.
To use manual shifting, you have two options:
Rtemporary setting
Rpermanent setting
If you activate manual gearshifting, the multi-function display will show the current gearinstead of transmission position[.
If manual gearshifting is deactivated, the gearswill be selected automatically.

Adaptive damping system
General notes
A suspension with the adaptive damping sys-tem provides improved driving comfort andcontinuously controls the calibration of thedampers. The damping characteristics adaptto the current operating and driving situation.
The damping is tuned individually to eachwheel and depends on:
Ryour driving style, e.g. sporty
Rthe road surface conditions
Rthe selected drive program (Ypage 132).
Selecting the Comfort or Economy
drive programs
In theComfortandEconomydrive programs,the driving characteristics of your vehicle aremore comfortable. Select one of these driveprograms if you favor a more comfortable driv-ing style. Also select these drive programswhen driving fast on straight roads, e.g. onstraight stretches of highway.
In urban traffic and stop-start traffic, drive pro-gramCis recommended.
XPress DYNAMIC SELECT buttonCrepeat-edly until theComfortorEconomydriveprogram is selected.

Setting the vehicle level
General notes
The vehicle level can be set using theDYNAMIC SELECT button (Ypage 132) or thelevel button. The setting always correspondsto the last selected function.
In order to reduce fuel consumption andimprove the driving dynamics, the vehicle islowered as its speed increases. In theSportandSport Plusdrive programs, it is loweredby up to 0.5 in (13 mm) compared to the nor-mal vehicle level. In theComfortandCURVEdrive programs, it is lowered by up to 0.2 in(5 mm) compared to the normal vehicle level.As the speed is reduced, the vehicle is raisedup to the set vehicle height.
Select the normal level for normal road surfa-ces and the raised level for driving with snowchains or on particularly poor road surfaces.
Important safety notes
GWARNING
The vehicle is lowered slightly in the follow-
ing situations:
Rthe SPORT suspension setting is selected
at the normal vehicle level
Rthe engine is switched off
Persons in the vicinity of the wheel arch or
the underbody may thus become trapped.
There is a risk of injury.
Make sure that nobody is in the vicinity of
the wheel arch or the underbody when you
switch off the engine.
