Not sure what you mean by rotors, but the engine light will not warn of brake wear. Engine light only comes on for service warning or beacuse af an engine fault. Hope this helps

Meaning of ABS light


On vehicles equipped with antilock brakes (ABS), a second warning light is provided to warn if a problem occurs within the ABS system. The ABS lamp comes on when the ignition is turned on for a bulb check, then goes out after the engine starts. If the ABS warning light remains on or comes on while driving, it indicates a fault has occurred in the ABS system.

What happens next depends on the nature of the fault. On most applications, the ABS system disables itself if the ABS warning light comes on and remains on.

Meaning of warning lights


Manufacturers spend billions of dollars a year refining their cars' on-board diagnostics systems. However, all of the sophisticated diagnostics in the world will do little good if you don't know what the warning lights mean.
Purpose
Modern automobiles have dozens of sensors to monitor engine, braking and chassis performance. Any deviation from the car's established limits will trigger a dashboard warning light.


Check Engine Light
Check engine lights can indicate failure of the emissions system, fuel injection system, faulty sensor feedback, overheating or lack of voltage, transmission failure, and engine knock ignition system failure.


Brake Lights
Almost all cars have two separate lights for the braking system: a red "ABS" (anti-lock braking system) light and "Brake Warning" light. The former indicates failure of the electronic anti-lock system, the latter a loss of fluid pressure in the brake system itself.


Dynamic Warnings
Many modern cars have traction or stability control systems that prevent and notify the driver of tire slippage. These lights can come in the form of amber "SLIP," "TC," or "TRACTION" lights (for spinning tires), or "ESC" (electronic stability control) lights for a sliding vehicle.


Safety Lights
Most cars have a diagrammatic warning that indicates a door that isn't all the way closed, a seat-belt warning light, and an "airbag disabled/enabled" light. Any or all of these will be red or amber.

Why does my traction off light come on?


You either have a problem with your engine control system, the traction control system, or you are not in the correct gear. See the explaination below. This is from the 2000 Chevrolet Cavalier Owner's Manual.

TRAC-OFF LIGHT

... If you turn the system off by moving the shift lever

to FIRST (1) or SECOND (2), the warning light will

come on and stay on. To turn the system back on,

move the shift lever back to a position other than

FIRST (1) or SECOND (2). The warning light

should go off. (See "Enhanced Traction System"

in the Index for more information.)

 The warning light will come on when you set your

parking brake with the engine running, and it will

stay on if your parking brake doesn't release fully.

If the transaxle shift lever is in any position other

than FIRST (1) or SECOND (2) and the warning

light stays on after your parking brake is fully

released, it means there's a problem with the system.

 If the traction control system is affected by an

engine-related problem, the system will turn off

and the warning light will come on.

If the Enhanced Traction System warning light comes

on and stays on for an extended period of time when the

transaxle shift lever is in any position other than FIRST
(1) or SECOND (2) your vehicle needs service.

Emmissions light has come on?


you need to get it scanned, i assume "emissions light" is your check engine light, or the "visit emissions workshop" message, which means, go to a shop and get it checked. The coolant disappearing means you probably have a leak. Another reason to check it,

99 nissan cefiro. An orange warning light comes on which looks like an engine. What does this mean?


This is the 'Check Engine' warning light. This normally comes on when there are sensors (usually the engine knock sensor) that are faulty or indicate some type of engine trouble.

Have this diagnosed by a qualified technician immediately.

Hope this helps.

Check engine warning light


have you taken it in to be diagnosed? usually car shops will hook it up to their diagnostic machine to tell you what the "code" means and why the engine light is on. they also can re-set it for you, to see if it comes back on or not. only takes a minute.

Jeep 95 warning lights ?


The gentleman above gave you the correct starting point. There are red and amber lights. Amber usually indicates a problem with the engine electronics or emissions system. Red lights are related to charging or alternator problems and engine overheating. If a light comes on you need to check the related system before you wind up disabled on the side of the highway.
