Automatic gearbox -- Powershift*
An automatic gearbox with Powershift differs from an automatic gearbox with Geartronic (p.273), in that it has double mechanical clutchdiscs.
D : Automatic gear positions. +S–: Manual gear
positions. S: Sport mode*.
The Powershift automatic gearbox transmits the motive force from the engine to the drivewheels with double mechanical clutch discs,as opposed to Geartronic which instead usesa hydraulic torque converter. Powershift transmission operates in the same way and has similar controls and functions asthe Geartronic automatic transmission. Oneexception is Geartronic's Winter mode, seethe section "Geartronic - Winter mode" (p. 273). Powershift enables driving away on aslippery road surface if 2nd gear is engagedmanually instead of 3rd gear (Geartronic).
Powershift or GeartronicThe model with Powershift transmissionshould not be towed as it is dependent on theengine running in order to receive sufficientlubrication. If towing still has to take place,the route must be as short as possible andthen with very low speed. In the event of uncertainty as to whether or not the car is equipped with Powershift trans-mission, this can be verified by checking thedesignation on the gearbox label under thebonnet - see Type designations (p. 386). Thedesignation ”MPS6” means that it isPowershift transmission - otherwise it isGeartronic automatic transmission.
To bear in mindThe transmission's double clutch has over-load protection that is activated if it becomestoo hot, e.g. if the car is held stationary withthe accelerator pedal on an uphill gradient fora long time. Overheated transmission causes the car to shake and vibrate, and the warning symbolilluminates and the combined instrumentpanel shows a message. The transmissioncan also overheat during slow driving inqueues (10 km/h or slower) on an uphill gradi-ent, or with a trailer hitched. The transmissioncools down when the car is stationary, withfoot brake depressed and the engine runningat idling speed. Overheating during slow driving in queues can be avoided by driving in stages:
• Stop the car and wait with your foot on the brake pedal until there is a moderatedistance to the traffic ahead, drive for-ward a short distance, and then waitanother moment with your foot on thebrake pedal.
IMPORTANT
Use the foot brake to hold the car station- ary on an uphill gradient - do not hold thecar with the accelerator pedal. The gear-box could then overheat.
For important information regarding Power- shift transmission and towing, see Towing (p.313).
Text message and actionIn some situations the combined instrumentpanel may show a text message at the sametime as a symbol is illuminated.

Start/Stop* - the engine does not stop
Some engine and gearbox combinations are equipped with a Start/Stop function whichengages in the event of e.g. stationary trafficor waiting at traffic lights. Although theStart/Stop function is activated, the enginedoes not always stop automatically. The engine does not auto-stop if:

Start/Stop* - the engine auto-starts
Some engine and gearbox combinations are equipped with a Start/Stop function whichengages in the event of e.g. stationary trafficor waiting at traffic lights. An auto-stoppedengine may restart in certain cases withoutthe driver having decided that the journeyshould continue. In the following cases the engine also starts automatically if the driver has not depressedthe clutch pedal (manual gearbox) or takeshis/her foot off the brake pedal (automaticgearbox):

WARNING
Do not open the bonnet when the engine has stopped automatically - the enginemay suddenly start automatically. Firstswitch off the engine as normal using theSTART/STOP ENGINE button before
opening the bonnet.

WARNING
•Check that the steering lock is unlocked before towing.
• The remote control key must be in keyposition
II - in position I all airbags are
deactivated.
• Never remove the remote control keyfrom the ignition switch when the caris being towed.
WARNING
The brake servo and power steering do not work when the engine is switched off - thebrake pedal needs to be depressedabout 5 times more heavily and the steer-ing is considerably heavier than normal.
Manual gearboxPrior to towing:
–Move gear lever into neutral and release the parking brake.
Automatic gearbox GeartronicPrior to towing:
–Move the gear selector to position
N and
release the parking brake.
Automatic gearbox PowershiftThe model with Powershift transmission should not be towed as it is dependent on theengine running in order to receive sufficient lubrication. If towing still has to take place,the route must be as short as possible andthen with very low speed. In the event of uncertainty as to whether or not the car is equipped with Powershift trans-mission, this can be verified by checking thedesignation on the gearbox label under thebonnet, see Type designations (p. 386). Thedesignation ”MPS6” means that it isPowershift transmission - otherwise it isGeartronic automatic transmission.
IMPORTANT
Avoid towing.
• However, the car can be towed for a short distance at low speed to move itfrom a dangerous position - not furtherthan 10 km and not faster than10 km/h. Note that the car mustalways be towed with the wheels roll-ing forward.
• In the event of moving a longer dis-tance than 10 km, the car must betransported with the drive wheelsraised from the road - professionalrecovery is recommended.
Prior to towing:
–Move the gear selector to position
N and
release the parking brake.
Jump startingDo not tow the car to bump start the engine. Use a donor battery if the battery is dis-charged and the engine does not start, seeJump starting with battery (p. 270).
IMPORTANT
The catalytic converter may be damaged during attempts to tow-start the engine.

Bonnet - opening and closing
The bonnet can be opened when the handle in the passenger compartment has beenturned clockwise and the lock by the grille hasbeen moved to the left.
The handle for bonnet opening is always on the left-hand side.
Turn the handle about 20-25 degrees clockwise. You will hear when the catchreleases.
Move the catch to the left and open the bonnet. (The catch hook is locatedbetween the headlamp and grille, seeillustration.)
WARNING
Check that the bonnet locks properly when closed.

Some oils and fluids should be checked at regular intervals.
Regular checkingCheck the following oils and fluids at regularintervals, e.g. when refuelling:
• Coolant
• Engine oil
• Power steering fluid (not cars with 4-cyl. 2.0 litre engine 4
)
• Washer fluid
WARNING
Remember that the radiator fan (located at the front of the engine compartment,behind the radiator) may start automati-cally some after the engine has beenswitched off. Always have the engine cleaned by a workshop. There is a risk of fire if theengine is hot.

IMPORTANT
If the wiper arms in service position have been folded up from the windscreen, theymust be folded back down onto the wind-screen before the wipers are allowed toreturn to their starting position. This is toavoid scraping the paint on the bonnet.
Replacing the wiper blades
Fold up the wiper arm when it is in serv- ice position. Press the button located onthe wiper blade mounting and pullstraight out parallel with the wiper arm.
Slide in the new wiper blade until a "click" is heard.
Check that the blade is firmly installed.
4. Fold the wiper arm back towards the windscreen.
The wipers return from service position to their starting position when you briefly pressthe START/STOP ENGINE button to set the
car’s electrical system to key position I (or
when the car is started).
NOTE
The wiper blades are different lengths. The blade on the driver's side is longer than onthe passenger side.
