Most Important Warning Lights
Engine Overheating
Common causes
- Low coolant level
- Clogged radiator fins (grass/debris)
- Faulty thermostat
What to do
On the eMax 22S, stop the engine, let it cool, clean the radiator screen with compressed air, and top off coolant with a 50/50 mix of antifreeze and water. If recurring, inspect the water pump and thermostat.
Low Oil Pressure
Common causes
- Low engine oil level
- Oil filter clogged
- Oil pump failure or worn engine
What to do
For the eMax 22S, shut down immediately, check the dipstick, and add 10W-30 diesel oil to the full mark. If light persists, do not restart; contact a Mahindra dealer.
Charging System Failure
Common causes
- Loose or broken alternator belt
- Faulty alternator
- Corroded battery terminals
What to do
On the eMax 22S, inspect the alternator belt tension and condition; tighten or replace if needed. Clean battery terminals with a wire brush and check for voltage output (should be ~14V when running).
Water in Fuel
Common causes
- Contaminated fuel
- Condensation in tank
- Faulty fuel cap seal
What to do
On the eMax 22S, locate the water separator bowl (under the left side of engine) and turn the drain valve until clear fuel flows. After draining, prime the fuel system by turning the key to 'on' without starting for 10 seconds.
Engine Check Light (Emissions)
Common causes
- Loose fuel cap
- Injector issue
- EGR valve carbon buildup
What to do
On the eMax 22S, first tighten the fuel cap; if light stays on after restart, the tractor may need a dealer diagnostic. Avoid prolonged idling to prevent EGR clogging.
Frequently Asked Questions
How do I reset the service light on my Mahindra eMax 22S?
The service light (hour meter) is automatically reset only by a dealer. You can clear the warning by holding the dashboard button while turning the key to 'on', but the underlying service interval reminder will reappear after engine operation.
Why does my glow plug light stay on longer than usual?
On the eMax 22S, the glow plug light stays on longer in cold weather (below 40°F). If it remains on for more than 15 seconds or flashes, the glow plugs or controller may need inspection.
What should I do if the PTO light flashes?
A flashing PTO light on the eMax 22S indicates a fault in the PTO engagement circuit. Disengage the PTO, turn the ignition off, and check the PTO switch and wiring for damage. If the issue persists, consult your dealer.
Can I drive with the master caution light on?
Yes, but with caution. The eMax 22S will continue to operate, but you should check the information display for the specific caution (e.g., low fuel, water in fuel) and address it promptly to avoid escalation.
How do I check the transmission oil level on the eMax 22S?
Park the tractor on level ground, engage the parking brake, and locate the transmission dipstick under the seat. Wipe it, reinsert, and check that the oil is between the marks. Use Mahindra hydraulic/transmission fluid (SAE 10W-30).
What does the blue high beam light mean?
It simply means your headlights are on high beam. On the eMax 22S, push the turn signal lever forward to toggle high beams; pull back to flash. Use low beam when working near others.
