You’ve just stepped into an electric vehicle for the first time. It’s quiet, almost eerily so. You press the start button and instead of a roar, you get a dashboard lit up with symbols you’ve never seen before. Sound familiar?
Unlike petrol or diesel cars, electric vehicles carry a set of warning lights that are entirely unique to EVs. These indicators monitor systems that simply do not exist in conventional vehicles, high-voltage battery packs, electric motors, charging ports, and intelligent power management systems.
This guide covers only the EV-exclusive warning lights sourced directly from EV manufacturer manuals and verified against global EV safety references. No petrol or diesel lights here. Just what you need to know as a first-time EV driver in Singapore.
Quick colour rule: 🟢 Green = all good | 🟡 Yellow = caution, act soon | 🔴 Red = stop driving now.
EV-Exclusive Warning Lights: Complete Reference Guide
All 12 indicators below are found only in electric vehicles. They do not appear in petrol or diesel cars. Learn these and you’ll never be caught off guard on the road.
Power Battery Cut-Off Indicator (Yellow)
The high-voltage battery has been automatically disconnected as a safety measure. Do NOT attempt to restart the vehicle. Contact your service provider immediately.
Driving State Indicator (Green)
Your EV is on and ready to drive. Because EVs are silent at startup, this green READY light is the only confirmation the vehicle is live. If it does not appear, the vehicle has not started.
Charging Status Indicator (Yellow)
The vehicle is connected to a charger or a charging session is active. Yellow = charging in progress or a charging anomaly detected. Always unplug before driving.
Charging Cable Connection Indicator (Red)
The charging cable is still physically plugged into the vehicle. RED = do NOT drive. You will damage the cable, charging port, and risk injuring bystanders. Disconnect the cable first.
Power Limit Indicator (Yellow)
The vehicle is restricting motor output to protect the battery usually when the battery is too hot, too cold, or critically low. Performance is reduced. Drive gently and find a charging point or shaded parking.
Motor Fault Warning Light (Red)
A fault has been detected in the electric motor or motor controller. Pull over safely, switch off, and call for assistance. Do not continue driving.
System Fault Warning Light (Red)
A fault in the core electrical drive system – inverter, controller, or high-voltage circuit. Stop immediately. This can indicate risk of electrical failure. Seek professional help at once.
Battery Fault Warning Light (Red)
A fault in the 12V auxiliary battery that powers the vehicle’s electronics. Red = potential total system shutdown. Park safely and call for service immediately.
Power Battery Fault Warning Light (Red)
Critical fault in the main high-voltage traction battery pack. Stop driving immediately. Risk of battery damage, thermal event, or complete power loss. This is the most serious EV warning light.
Low Battery Indicator (Yellow)
The EV equivalent of a low fuel light. Battery charge is critically low – find the nearest charging station now. Unlike petrol cars, you cannot coast to a pump. Charge before hitting 15-20%.
ECO Status Indicator (Green)
ECO driving mode is active. The car is limiting power output to maximise range. This is a positive indicator – it means the vehicle is conserving energy. No action needed.
CCS ON Indicator (Cruise Control System) (White/Green)
Cruise control is active. In EVs, disengaging cruise control resumes regenerative braking – be aware of the change in braking feel when switching off.
⚠️ Any RED light means stop the vehicle safely and do not continue driving. Call your rental provider or roadside assistance immediately.
4 Things Every First-Time EV Driver Must Know
- READY is your ignition light. No engine sound is normal. If READY glows green, you are live and driveable.
- Never drive with the charging cable still plugged in. The red Charging Cable Connection light is an EV-exclusive risk, one that petrol drivers never face.
- Charge before you hit 20% battery. There is no coasting to a pump. Singapore’s EV charging network is growing, plan your route and charge ahead of time.
- Never tow an EV the same way you would a petrol car. EVs cannot be flat-towed. Doing so forces the electric motor to spin without power, causing serious and costly damage to the drivetrain. Always use a flatbed truck. Find out why towing an EV is completely different here
