Sometimes while driving long distance an alert sign comes up. Looks similar to
( ! ).

I dont believe its the tire pressure because i already checked that. Does anyone know the problem?

 

if its an ! enclosed in a circle and parentheses than it is a brake warning light. If its an ! with parentheses and a line at the bottom than its the tire pressure warning. There is something wrong with whichever sensor it is

 

It's your TPMS telling you there is low pressure in at least one tire.

Ifr you did a manual check and all is well, it may be a malfunction.

Quit looking at the gauges, & pay aTTention to the road.

 

If its the brake warning light, then he should be paying attention to it, I is a very important warning light. It signals the driver that there may be something wrong with the brake system.

But, I agree people should pay more attention to the road.

 

If it's a light that comes on after 30-45 minutes of driving, then it's the TPMS warning telling you that one or more of the sensors is not being detected. Do you have aftermarket wheels on your Z? Do they have the original TPMS sensors installed?

If you're sure you have the sensors installed, then one or more of them is not working and the system is not detecting it.

 

I believe it is the brake warning light. Your fluid might be a little low or the pads might be wearing out.

 

So I have low tire pressure but haven't had time to put air in my rear right tire. Will an audible warning tone go off when the sensor registers low pressure?

 

^What he said....exactly.

The computer is not picking up one or more of your tpms monitors...this is the only reason light should come on after 30-45 mins.

It is NOT braking system, and it is NOT low pressure warning.

To test if pressure is low after warning light appears, stop car, turn off, then turn back on....light and audible signal should appear instantaneously. If it does not, and only comes on after driving long period, problem is what is stated above.

 

If the pressure drops below about 28psi, then yes, you should get a warning. Once you put air in and drive it again, the warning should go off.

 

Most likely just an undetected TPMS Sensor. It goes off after about ~30 miles of driving

 

i have that problem the light goes on after 30 minutes, if i turn the car off and turn it on again, the light goes off, but after 30 minutes it goes on again...

if it's ur TPMS, and your tires are maintaining pressure. then check ur tires for a nail/screw or some sort of these things.

i've been in the same situation couple of times..

 

They r mantaining pressure, i already checked it, and i still have the problem, i check for any nail, or something like that and nothing...

i only have the problem after 30 minutes, if i turn off the car, the like turns off, and if drive for 30 minutes it goes on again...
