Start/stop system
Please note the information on Link.
- Never run the engine in confined spaces. The exhaust gases are toxic – risk of poisoning!
- Never switch off the engine until the vehicle is stationary.
- The brake servo and the power steering system work only when the engine is running. You need more strength to steer and brake the vehicle when the engine is switched off. This would mean a greater risk of accidents and serious injury, because you cannot steer and brake in the normal manner.
Caution!
Avoid high engine speeds, full throttle and extreme load conditions until the engine has reached its normal operating temperature; otherwise this can damage the engine.
Note
- When starting from cold the engine may be a little noisy for the first few seconds until oil pressure has built up in the hydraulic tappets. This is quite normal and no cause for concern.
- If you leave the vehicle with the ignition switched on, it will be switched off automatically after a while. Please note that electrical equipment such as the exterior lighting will also be switched off.
