Whilst driving in stop start traffic on a hot day last week i heard 3 or 4 dings then the temperature warning light came on.i pulled over to let it cool down for 10 mins,checked the coolant. that was ok,, then carried on with my journey.the light never came back on.is this normal?

Fans are controlled by a temperature sensor on the engine block. I would start there - verify the wiring for a fuse problem and if OK, replace the sensor.

Sound like a brake on warning so you don't put in gear and drive with the break on however a brake light should come on but it maybe Burt out

one of the door ajar switches are sticking. needs to be put on the computer to find out which one. only other way is to go around and unplug the switches until your light shuts off.

I have a 2001 Suzuki Ignis and I have a similar problem. When I start the engine 5 beeps are heard and the hazard lights turn off and on with each beep. Also after I have been driving for about 45 mins 3 beeps are heard and the hazard lights turn off and on again. However my engine does not stop running. I have asked people about it and they think that it has something to do with a lose wire in the security system? Any help would be greatly appreciated!

sounds like a blown head gasket letting coolant get injected into the engine and getting burned with the fuel. a head gasket replacement should help

do you have a electric fan or a fan clutch?

Check the output sensor on the transmission,
With out a speedometer the transmission does not know how fast you are going or when it should shift

Throughout my experience with Toyota's I have found that several times the hubcaps have made some weird noises. Try removing your hubcaps and driving your vehicle. If the noise still persists please let me know and I can ask u some questions and try to help you with your problem.

change you pcv vavle and distrubter rotor

Seems like you might have a couple of problems. First the gas gauge, check your fuses to see if they are still good. Then check the wiring as you may have a short or a bad ground. Lastly if everything checks out then you may have faulty sensor in the gas pump housing in the gas tank, and or faulty temperature sending unit located on the motor. As for your your overheating issue you may have a head gasket leak which these little motors are prone to having, or just a general coolant leak. I deduced this because you're constantly having to refill with water. You have a leak somewher, but to narrow it down to your head gasket check your oil to see if it's got coolant in it. It will look like chocolate milk and may even smell like coolant. Also check your tailpipe with the car running in park and up to operating temp, if you see white smoke coming out the tailpipe that white smoke isn't smoke but water vapor, caused by water entering the combustion chamber from the leaking head gasket and exiting the exhaust. Also you may have a faulty fan switch on your radiator. This would cause your engine to heat up drastically in bumper to bumper traffic because when you're driving cool air is rushing through your radiator, and when you slow down and stop so does the air flow, and if your fan doesn't kick in your radiator isn't able to do it's job and cool the coolant. Hope this helps.
