Switching DSA off
The system comes on automatically each time you start the engine. Switch DSA off by pressing the
switch and holding it down for more than half a second. The control light will come on to show that
DSA is switched off.
We recommend that you switch the system off whenever you use the "Special Spare" tire that does not
match the diameter of your other tires.
Switching DSA on
If DSA is switched off, switch it on by pressing the DSA button. The system will also switch on
automatically whenever you restart the car.

When you switch the ignition on, the control light on the dashboard should come on briefly (until 2
seconds after starting the engine).
If the light stays on, this means there is a fault detected in the system.
