Transmission Settings
The iDRIVE works equally well on both automatic and manual transmissions. There
is an internal setting that changes the voltage pattern to suit. There is a slightly
softer setting to compensate for the direct drive nature of the manual transmission.
The manual transmission setting can also be used for vehicles equipped with
automatic transmissions if the driver feels that the response is too sensitive.
Changing Settings
Through our own rigorous testing, we have determined that there can be absolutely
no damage done to a vehicle though changing settings while driving. Drivers can
change through the iDRIVE's modes at any time, however we don’t recommend
changing the settings while the accelerator is depressed, preferably while stopped
at a traffic light or in traffic.
Fuel Economy
In testing we have seen a wide range in fuel economy savings, it largely depends
on the make and model of the car, as well as the driving style of the user. However
a large percentage of drivers see a noticeable increase in fuel economy by using
both the Automatic and lower Ultimate modes, this is mostly due to more efficient
use of the throttle.
Towing
Eco mode can help to delay the throttle response so the driver can concentrate on
the slight corrections of the steering wheel when reversing the trailer and reduce
over correction. Also, the higher ultimate modes are great for getting the vehicle
moving with extra weight, particularly handy towing uphill’s of from a standing start.
Sand/Mud
When bogged in soft sand you need a far slower wheel speed to be able to drive
out, Eco Mode with its dampened throttle response can often unstick a vehicle
without the need for recovery gear. 4wding Higher Eco settings are perfect for
4wding, especially across bouncy terrain, the dampened throttle response prevents
jerky acceleration from the bouncing foot of the driver. Higher Ultimate performance
setting can help with quick bursts of acceleration to get out of muddy holes as well
as flick clogged mud from the tyres, improving grip
