Advised Gear Change on Aygo

[kieranam1904]

So only had my second Aygo Just over a month now, Used to have a 62 Plate Aygo and loved it including the modifications I made (eg: satnav & touchscreen display in the dash) and just recently when doing 70mph on the motorway in fifth gear (5) the car begins to advise me to change down a gear into (4) fourth gear?? 

finding it a little strange is it something to do with a filter that needs blowing out or something? Don't want to phone Toyota if its just me being daft!

Can someone inform me?

Is it because you're going up an incline?

The quoted maximum speed in 4th is 88mph.

it doesnt seem to matter of the incline or decline etc. it just happens strangely at sporadic times. no rhyme or reason to this happening that I Can work out.

 

thank you for your quick reply to this thread though
