LS Tractor MT235E Warning Light Symbols
| Symbol | Name | Color | What it means | What to do |
|---|---|---|---|---|
| Master Warning (Stop) | RED | Illuminates for critical faults like engine shutdown or brake failure on the MT235E; demands immediate attention. | Stop tractor safely, turn off engine, consult manual. | |
| Master Caution | AMBER | Lights for non-critical issues such as a clogged fuel filter or low hydraulic fluid on the MT235E. | Check the display for the specific caution message and address as needed. | |
| Check Engine (MIL) | AMBER | Indicates an engine management fault, like a sensor failure or emission issue, on the MT235E's diesel engine. | Contact your LS dealer for diagnostic scanning. | |
| Engine Oil Pressure | RED | Low oil pressure warning for the MT235E engine; may be caused by low oil level or pump failure. | Stop engine immediately and check oil level; if OK, call for service. | |
| Battery / Charging | RED | Indicates charging system fault, like a bad alternator or loose belt, on the MT235E. | Check battery connections and alternator belt; if persists, service required. | |
| Coolant Temperature | RED | Engine overheating on the MT235E; often due to radiator blockage or low coolant. | Stop tractor, let engine cool, check coolant level and radiator cleanliness. | |
| Transmission Temp | RED | High transmission temperature in the MT235E HST or gearbox; avoid heavy loads until cool. | Reduce load, idle engine to cool, check transmission fluid level. | |
| Brake System | RED | Indicates a brake system fault, such as low fluid or worn pads on the MT235E. | Check brake fluid reservoir and inspect brake components; do not operate until fixed. | |
| Parking Brake | AMBER | Reminds that the parking brake is applied on the MT235E; release before driving. | Release parking brake to extinguish light. | |
| Glow Plug / Preheat | AMBER | Active during cold start preheating on the MT235E; wait for it to turn off before cranking. | Turn key to preheat, wait for indicator to go out, then start engine. | |
| Water in Fuel | AMBER | Water detected in the fuel filter/separator of the MT235E; drain immediately to avoid injector damage. | Drain water from fuel filter bowl; if frequent, check fuel source. | |
| Low Fuel | AMBER | Fuel level is low on the MT235E; refuel soon to avoid air in system. | Add diesel fuel to the tank. | |
| High Beam | BLUE | High beam headlights are on for the MT235E. | Toggle high beam stalk to switch off. | |
| PTO Engaged | GREEN | Rear PTO is engaged on the MT235E; be cautious near rotating shafts. | Disengage PTO when not in use. | |
| Differential Lock | GREEN | Differential lock is engaged on the MT235E for increased traction. | Disengage diff lock when turning on hard surfaces. | |
| Seat Belt | RED | Seat belt is not fastened on the MT235E; safety interlock may prevent starting. | Fasten seat belt to allow operation. | |
| Air Filter | AMBER | Restricted air intake filter on the MT235E engine; clean or replace element. | Inspect and service air filter per manual. | |
| Fuel Filter / Water Separator | AMBER | Fuel filter needs service or water in separator on the MT235E. | Replace fuel filter and drain water separator. | |
| Service / Hour Meter | AMBER | Indicates scheduled maintenance is due based on engine hours on the MT235E. | Perform required service per the maintenance schedule. | |
| Work Lights | GREEN | Additional work lights are activated on the MT235E for nighttime tasks. | Toggle work light switch to turn off. | |
| Hydraulic System | RED | Hydraulic system fault detected on the MT235E, such as low fluid or overheating. | Check hydraulic fluid level and filter; if hot, let system cool. |

Most Important Warning Lights
Engine Overheat
Common causes
- Low coolant level
- Radiator debris blockage
- Failed cooling fan
What to do
Stop tractor immediately. Once cool, check coolant and clean radiator fins. If persists, inspect fan belt and thermostat at LS dealer.
Low Oil Pressure
Common causes
- Low engine oil level
- Oil pump failure
- Clogged oil filter
What to do
Shut off engine. Check oil dipstick; add oil if low. If level is fine, do not restart—call for service to avoid engine damage.
Transmission Overheat
Common causes
- Continuous heavy load
- Low transmission fluid
- Clogged cooler
What to do
Stop tractor and idle to cool transmission. Check fluid level and clean cooler fins. Reduce load in future operations.
Brake Failure
Common causes
- Brake fluid leak
- Worn brake pads/shoes
- Air in hydraulic brake line
What to do
Do not operate. Check brake fluid reservoir and lines for leaks. Top off fluid and bleed brakes. Replace worn components at dealer.
Charging System Fault
Common causes
- Loose alternator belt
- Bad alternator
- Battery terminal corrosion
What to do
Check belt tension and battery connections. Clean corrosion. If battery light stays on, alternator may need replacement.
Frequently Asked Questions
Why does the glow plug light stay on for a long time on my MT235E?
In cold weather, the MT235E's glow plugs may preheat longer. If the light stays on more than 10 seconds without starting, check the glow plug relay or plugs at an LS dealer.
Can I ignore the water in fuel warning temporarily?
No—water can damage the injection system. Drain the fuel filter bowl immediately as shown in the operator's manual. If it recurs, check your diesel source.
What does the master caution light mean if no other light is on?
The master caution indicates a non-critical warning stored in the system. Check the LCD screen for a message (e.g., fuel filter service or low DEF if equipped).
How do I reset the service hour meter after an oil change?
The MT235E service interval reset is not user-adjustable on some models. Consult your dealer or manual; typically, they reset it during scheduled maintenance.
Why does my PTO light flash when the PTO is off?
A flashing PTO light usually indicates a fault in the PTO switch or wiring. Have the tractor inspected by an LS technician to avoid accidental engagement.
Is it normal for the transmission temp light to come on during heavy mowing?
Not normal. The MT235E's transmission is designed to handle light to moderate loads. Stop and check fluid level and cooler cleanliness. If fine, reduce ground speed.
