This is usually informational. Address it at your convenience.
What the Overdrive (O/D Off) Light Means on a Nissan GT-R
The overdrive (O/D OFF) light on a Nissan GT-R shows that overdrive — the transmission's fuel-saving top gear — has been switched off, usually via a button on the shifter. It is a driver setting, not a fault.
How Urgent Is the Overdrive (O/D Off) Light?
How worried should you be? For the Overdrive (O/D Off) Light on a Nissan GT-R, the urgency is low.

Frequently Asked Questions
Why is the Overdrive (O/D Off) Light on in my Nissan GT-R?
On a Nissan GT-R, the Overdrive (O/D Off) Light comes on because a monitored value crossed a threshold the car considers abnormal. It could be a simple, inexpensive cause or a genuine fault — the only way to be sure is to scan the vehicle and interpret the codes rather than guess from the symbol alone.
Can I keep driving with the Overdrive (O/D Off) Light on?
Short answer: sometimes, but not indefinitely. Given this indicator's low priority, respect the warning colour and the car's behaviour. When in doubt with your Nissan GT-R, the safe choice is to stop and have it checked rather than risk further damage.
How much does it cost to fix the Overdrive (O/D Off) Light on a Nissan GT-R?
Cost varies widely because the Overdrive (O/D Off) Light can stem from several causes on a Nissan GT-R. Some fixes are almost free — tightening a cap or a connector — while others involve a sensor or component and its labour. Getting the specific trouble code first is what lets a shop quote accurately instead of estimating blind.
Will the Overdrive (O/D Off) Light reset itself on a Nissan GT-R?
Sometimes the Overdrive (O/D Off) Light on a Nissan GT-R clears on its own once the condition that triggered it no longer exists — for example after several good drive cycles. More often, though, the light stays on until the underlying fault is repaired and the code is cleared, so treat a self-clearing light as a reason to still investigate.
