A vehicle is an Electro-Electronic-Mechanical machine, with electric, electronic(some time wireless), magnetic, devices and parts. These devices and parts emit magnetic and electric fields in different frequencies.
It is possible that the manufactures or the car, its' importers or the dealers of the car might tell you that the EMF radiation levels of the car your interested in were tested and were found to be complied with the current safety standards. There are clearly right. But if you are familiar with EMF safety standards and guide lines you should already know that the so called safety standards are outdated, based on life threaten effect, are not based on any biological risk and are generally very high. In same cases the devices are not even tested for safety since their output power is considered to be very low (and most of time require no testing). However this does not mean that the emission from these devices is safe or durable, specially in the case of EHS people.
The protection of the inside space of a car from radiation emission from inside the car parts and devices can be very expensive and complicated. In the case of ELF protection it is very expensive and can't always be applied correctly in the car. In the cases of RF sources inside the car, the right approach should be to remove them, if possible. In the case of RF radiation from outside the car, RF protection film can be installed (according to your country's law) on some of the windows. In some cases protection will be impossible.For EHS people, the use of RF Protection Hats and Clothes for EHS people might also help to some extent. There for we recommend on test EMF levels (both ELF magnetic, electric and RF radiation) before buying the car, to make sure the EMF levels in the car is suitable for you.
If Radiation exposure issues are important to you and you want to reduce exposure also when driving your car, or in the case you are suffering from EHS and you need the exposure inside the car to be minimum as possible, we advice to check and test EMF levels in every car you are interested in , while using a home use EMF meter. According to what the meter shows you, you will have more info to make a knowledgeable decision if to buy the car or not.
The EMF tests should be done both in ELF magnetic field, ELF Electric field and RF radiation. The tests should be done over the sits, where your head, legs and body are going to be as a driver or a passenger, bellow the steering wheel and next to the paddles. It is also recommended to scan the car for devices which emit RF radiation.
All tests should be done in an environment with low EMF, so the reading will be of the radiation emitted from within the car and not from outside.
ELF magnetic field measurements next to the car paddles (acceptable levels)
Next we will try to note the different EMF sources inside a car and explain a bit about them. The following review is only general and not complete.
ELE EMF(mainly magnetic fields but also electric fields) will usually be emitted from the following systems in most vehicles. The exposure level of the driver and passengers will be dependable on the level of ELF EMF emitted from the devices and the distance of the driver/passenger from it:

Hybrid and Electric cars generally have more electric and electronic systems than diesel or gasoline cars. Tests done in 2009 for the Israeli Environmental Protection Ministry mapped the levels of EMF magnetic fields emitted from the electromagnetic systems in several models of Hybrid cars that were available in Israel at that time.
At first look there seems to be only some little issues, and the Average Levels on each sit are 5.5mG at the most(not low). But If you look deeper into the report you will see that the max levels measured on some of the sits, in some of the scenarios, reached much higher picks and average measurements.

From test I did using a home use meter in one model of hybrid car, and tests done in Israel by others, it seems that indeed there are ELF magnetic fields emitted from the hybrid car systems. This is only logical since hybrid and electric cars have much more electromagnetic parts and systems. Some of them are in the following list:
The following products and devices are usually add-ons to a car, sometime as part of a service or accessories kit. These devices emit RF radiation.
Most cars have a metal body and doors. This metal body can block RF radiation from outside the car. This can creates less cellular reception inside the car, which means that your cellphone (if you have one and use it in the car) might transmit higher levels of RF radiation(compared to the level it may produce outside the car). In addition some of whatever RF Radiation that will be produced by the cell phone, or other wireless device inside the car, will be reflected from the metal body back to the inside of the car.
If you need to use a mobile phone to make calls during driving the car, we recommend the use of a build-in car phone with an external RF antenna. This is the best safest way to communicate while driving, both from the driving safety point of view and the RF exposure perspectives.
In case that you don't have a build-in car phone, the next best option is to attach the mobile phone next to the front window (if the window is not coated with aluminium-metal based transparent film) which will allow better reception and usually less emission, and use the speaker phone option.
The worse thing is to use the phone while driving, holding it in the hand(a major driving safety issue) or putting it in a low position inside the cabin(might emit more RF Radiation).
The use of a Bluetooth wireless hand-free kit will free your hands to drive but will create more RF inside the car.
Please note that in general we don't recommend the use of wireless devices or smart phones inside the car.
In general we don't recommend the use of cellphone to talk while driving (driving safety issue).
