Automatic gearbox 130Automatic gearboxmultitronic
®
Applies to vehicles: with multitronic®IntroductionThe vehicle is equipped with an electronically controlled continu-
ously variable transmission (multitronic
®). Unlike conventional
automatics, the gear ratios are not shifted in fixed steps but contin-
uously variable. This gives smoother transmission and makes for
better fuel economy.
The gearbox selects the gear ratio and shifts up or down automati-
cally according to the gear change programmes stored in the
control unit ⇒page 133, “Dynamic gear control program (DCP)”.
The gearbox also has the tiptronic manual shift feature. This system
allows the driver to select gears manually if required ⇒page 134.
Please note that on vehicles with a multitronic gearbox, torque is
transmitted via a multi-plate clutch, and not via a torque converter
as on conventional automatics. This means that the car will not
“creep” as much as conventional automatics when the engine is
idling if you stop temporarily with the selector lever in position D, S
or R.
Applies to vehicles: with multitronic®General notes on using multitronic
®
The transmission ratio is varied continuously.Driving away from a standstill
– Press and hold the brake pedal.
– Press and hold the interlock button (the button in the
selector lever handle), move the selector lever to the
desired position, for instance D, and release the interlock
button.
– Wait for the gearbox to engage the gear (a slight move-
ment can be felt).
– Release the brake and press the accelerator ⇒.
Stopping briefly
– Apply the foot brake to hold the vehicle when stationary
(for instance at traffic lights).

Self-help 268Do not pull too hard with the towing vehicle and take care to avoid
jerking the towrope. When towing on a loose surface there is always
a risk of overloading and damaging the anchorage points.
Caution
If there is no oil in the gearbox or no lubricant in the automatic
transmission the car may only be towed with the driven wheels
lifted clear of the road, or transported on a special car transporter
or trailer.
Note
•
Note the regulations concerning towing.
•
The hazard warning lights of both vehicles must normally be
switched on. However, observe any regulations to the contrary.
•
Make sure that the towrope is not twisted, as otherwise the front
towline anchorage on your vehicle could work itself loose.
Front towline anchorage
The front towline anchorage is only mounted if the vehicle
has to be towed.
The screw connection for the towline anchorage is located
behind a cover cap on the right side of the front bumper.
– Take the towline anchorage out of the vehicle's tool kit
⇒page 255.
– To detach the cover cap from the bumper, firmly press
the lower part of the cap inwards to release it ⇒fig. 250.
– Screw the towline anchorage firmly all the way into the
screw connection ⇒fig. 251.After use, unscrew the towline anchorage and put it back in the
toolbox. Replace the cap in the bumper. The towline anchorage
should always be kept in the vehicle.
WARNING
If the towline anchorage is not screwed in as far as the stop, there
is a risk of the screw connection shearing off during towing (acci-
dent risk).
