Ok, so I grew up with an old school family that has always warmed up their cars before taking off. But I've noticed that the CX-5 is the first car that actually has a temp indicator and also the one vehicle that mentions in the manual that the car should not be driven until the temp (thermometer) light/indicator goes off and the engine is at operating temperature. Is it necessary to sit there and wait for the car to warm up before taking off?(uhm)there are many times when you just need to go!!
