140 Starting and driving<br />
Lock-up<br />
The transmission’s torque converter has a<br />
so-called lock-up function. This means that<br />
in gear, the torque converter is locked in,<br />
which reduces engine speed and fuel consumption.<br />
Kick-down<br />
When the accelerator is pressed down fully,<br />
a down change is made to optimize<br />
acceleration, e.g. for overtaking.<br />
Following this, the next higher gear will be<br />
selected at the optimum engine speed or, if<br />
you ease off the accelerator, before<br />
reaching this.<br />
Driving with a heavy load on hilly<br />
roads<br />
The transmission fluid can overheat when<br />
the gearbox is strained, for example, when<br />
driving with a caravan on hilly roads. To<br />
avoid the transmission fluid overheating,<br />
always drive with the selector lever in the<br />
D position. The adaptive gear change patterns<br />
are then active.<br />
High air temperatures or a faulty oil cooler<br />
can also cause the transmission fluid to<br />
overheat. Overheating reduces the service<br />
life of the fluid.<br />
WARNING<br />
Remember to use the braking effect of the<br />
engine (1st, 2nd or 3rd gear) when you<br />
are descending long or steep hills to<br />
spare the brakes.<br />
Overheating can cause the brakes to<br />
fade!<br />
Towing<br />
Towing of cars with automatic transmission,<br />
see page 167.<br />
Descending hills<br />
If the speed of the car increases while<br />
descending a steep hill, despite the accelerator<br />
being released, the control module will<br />
change down. If you desire more powerful<br />
engine braking, manually select a lower<br />
gear, see page 143.<br />
Limp-home<br />
NOTICE<br />
Do not tow a caravan or trailer if limphome<br />
mode is engaged.<br />
If the transmission malfunctions, the control<br />
module will activate limp-home mode.<br />
Driveability will be affected to varying<br />
degrees.<br />
the following message then appears on<br />
the DIC:<br />
Gearbox malfunction.<br />
Limited performance.
