Tips & tricks

Few months ago I replaced battery in my Mazdaspeed3. I bought VARTA Blue Dynamic D47 which fits perfectly. Some technical data below.
Article no.: 560 410 054 313 2
Parameters: 12 V / 60 Ah / 540 A
Dimensions: 232x175x225 mm
Battery replacement is not a rocket science, so I did not need guide, but my friend found this, I think you like it ;)

Mazdaspeed3 / Mazda 3 MPS is equipped with on-board computer. Simply press INFO button for a while and you can read actual fuel consumption, average fuel consumption, average speed and the approximate range on owned fuel. But I found information that on-board domputer is not enabled in some versions of Mazda 3. Normally in versions below Grand Touring you have to pay for that, but for some reason it is trivially easy to unlock it. Probably this works on 2006 and later models, but why not to try this trick? After all, it will not explode ;)

In mazdaspeed you have speedometer in miles per hour (mph) and odometer in miles. Also fuel consumption is measured in miles per galon (mpg). This is ok in United States, but one can change units displayed on dashboard to metric, when needed. To do this you need to:

As I wrote in last article I put a table with codes and their values and meanings, which I created based on my observations:

You will not find this in the manual, so probably not everyone knows that without any additional devices and without visiting Dealership you can test most of the indicators from the dashboard and change some settings in on-board computer. For example, I use this to change units of the fuel consumption from mpg to litres/100 km. It can be done "in-house", and the key in this case is code "60 d15". I will write about this in another article, first we need to enter to the service mode.

Mazdaspeed3 with automatic air conditioning has external temperature sensor. To change the inside/outside indication on the display, you need to press the AMB button placed on the panel next to the rear window heating switch. As far as I know, this button is only available with automatic air conditioning, so in the manual you won't be able to find it. My car was imported from the U.S. and by default displays the temperature in Fahrenheit degrees. However, this can be changed and it is even described in the manual. Just do the following:
