hey guys,

I got noob questions, my vehicle Mater warning light & a Tire pressure warning light on. Is that normal? for Master warning light on for low tire pressure? or it is something else worst??

Vehicle: 2008 IS250 RWD
Tire size: 18', 225/40/18 front, 255/40/18 rear
Indication: Master warning (red triangle !), tire warning (!).

I just want to check before taking it in to the dealer.

- Thank you in advance for any inputs

 

How about you start with the simple thing - check the air pressure in the tires... typically that is all that warning means... if it's been getting cold in your part of the country, remember that for every 10 degree change (colder) in temperature, you can assume approximately a 1 psi drop in air pressure on average...

 

Gotta agree with Mitsuguy... check your tire pressure. It is mostly low. Either that, or a bad sensor. But likely just low pressure...
