# Starting an Internal Combustion Engine (ICE)

## Starting the Engine

Once you’ve completed your checks and are seated comfortably:

1. Make sure the **parking brake** is on.
2. Check that the **gear lever** is in **neutral** (or ‘P’/‘N’ for automatics).
3. Press and hold the **clutch pedal** (if required).
4. - For key ignition: Turn the key to switch on the ignition — the **ignition** and **oil pressure** lights should appear. Wait for the **glow-plug light** (diesel engines) to go out, then turn the key further to start.
     - For button start: Press the **starter switch** as directed by the manufacturer.
5. Release the key or button as soon as the engine starts to avoid damaging the starter.

If the engine doesn’t start:

- Release the key or button, wait a moment, then try again.

When running, the engine should **idle smoothly**, and the **warning lights** should go out.

If the **oil pressure** or **ignition** light stays on, switch off immediately and have the issue checked — driving could damage the engine.

Move off as soon as possible; idling wastes fuel and increases emissions.

## Electric & Hybrid Vehicles

Electric and hybrid vehicles operate differently. Electric motors are silent and don’t idle — only the dashboard display confirms that the vehicle is “ready.”

In hybrids, the engine may start and stop automatically depending on driving conditions.
