You need to keep your foot on the foot brake to start ( Safety)
As said, a good length of Jump Leads.
When Stopping at Traffic light or whatever the car comes to a stop, just keep your foot on the foot brake otherwise the car will CREEP (Drive Forward)
Select ( D) that's all you need to use unless Reversing ( R), the other gears are hardly ever used unless your thinking of going up Snowdon.
Regards service / checking the Auto Oil, the oil now used in Auto Boxes in Lifetime so some of the box's does not need to be checked,
A lot of People get the hump when they are behind you at night with your foot on the Foot Brake, (Hard Luck) was my answer, sorry if that sounds selfish but you are away under 5mins.
The Auto gear are Lit up at night so you know what gear you are in ( D)
When you get the car Fruit, take it for a run & use every gear from (D1 D2 D3 D4 Then R, that's if the cars has all them forward gears, make sure the gears are Direct / clean / Clear with NO GRIDING when you try and select, you say a NEW, if it's a new second hand car, make sure you take someone that knows a bit with you, an Auto when giving trouble will cost you a lot of money so make sure it's checked right, have whoever check under the car, if it shows signs of RED OIL under the Sump Rear attached to the Auto Box, beware, there may be an Oil Seal problem, other than that, take your time until you get used to it, you will never get a manual again believe me.
