®, tiptronic (6-speed
gearbox)
Applies to vehicles: with multitronic® or tiptronicIntroductionApplies to vehicles with multitronic
® gearbox
The 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 166 .
If desired, you can also select the gears manually (tiptronic mode)
⇒ page 166 .
Please note that on ve hicles 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.

The vehicle is equipped with an electronically controlled 6-speed
automatic gearbox. The gearbox changes up and down automati-
cally .

Self-help
296Do not pull too hard with the towi ng 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 bo th vehicles must normally be
switched on. However, observe an y 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 ou t of the vehicle's tool kit
⇒ page 283 .
– To detach the cover cap from the bumper, firmly press the lower part of the cap inwards to release it ⇒fig. 280.
– Screw the towline anchorage firmly all the way into the screw connection ⇒fig. 281.After use, unscrew the towline anchorage and put it back in the
toolbox. Replace the cap in th e bumper. The towline anchorage
should always be kept in the vehicle.
WARNING
If the towline anchorage is not scre wed in as far as the stop, there
is a risk of the screw connection shearing off during towing (acci-
dent risk).
