Frequently Asked Questions
What do I do if the DPF regeneration light comes on while I'm working?
For the New Holland T5.100, the solid amber light indicates passive regeneration is happening; you can continue working. If it flashes, you need to perform a stationary regeneration: park the tractor, engage the parking brake, and follow the prompts on the display to start the process.
Why is my check engine light on, and can I still drive the tractor?
On the T5.100, a solid check engine light means a fault is detected but you may continue operation with reduced power. However, if it's flashing, stop immediately. Use the instrument panel to retrieve fault codes or contact your dealer.
How do I reset the service hour meter on my T5.100?
The service indicator on your T5.100 can be reset via the electronic controller after performing the required maintenance. Navigate to the service menu and select 'Reset' or follow the instructions in your operator's manual.
What does the amber water in fuel light mean, and how do I fix it?
On the T5.100, this light indicates water has accumulated in the fuel water separator. To fix it, locate the drain valve on the fuel filter housing, place a container under it, and open the valve until clean fuel flows. Replace the filter if needed.
Can I operate the tractor with the transmission temperature light on?
No, a red transmission temperature light on your T5.100 indicates overheating that can cause damage. Stop the tractor immediately, reduce load, and let the transmission cool. Check oil level and cooler cleanliness before resuming work.
How do I activate the differential lock on my T5.100?
On the T5.100, the differential lock is engaged by pressing a button or pedal (depending on configuration). The green indicator will illuminate when locked. Use it only when traction is needed, and disengage before turning to avoid driveline damage.
