Heeeellp!! Newby VZ’er

[05VZ2NV]

Hi All,
I’m new on the VZ block and was hoping to get some help or pointed in right direction PLEEEAASEE???!

So I brought my 2005 VZ Acclaim last week off a very shady appearing seller (lol!) car was cheap looked good condition n I needed a car
ASAP so ignored my gut when it was telling me to turn n run and paid the guy n drove.... hence knowing nothing bout my new ride lol....

Here’s help I’m in need of;
1. Locating a owners log book?
2. My car is dual fuel - something I kno f**k all about - how do I find if was factory or aftermarket footed n how to find make etc of lpg system?
3. Instructions on using dual- fuel system?
4. Can I stop that annoying beeping sound when I reverse?
5. This is a great site n I’ve learnt heaps already, that’s in the spare 2mins I get to look at my phone - example it’s taken me over an hour just to type this!!! So I ask; Is there any other VZ Acclaim advice you can offer this time poor single mumma?!

Any help/info will be greatly appreciated!

Thanks in advance
