Please note the information on Link.
- Never run the engine in confined spaces. The exhaust gases are toxic – risk of poisoning!
- Always take the key with you when you leave the vehicle. Otherwise the engine can be started or power-operated equipment such as the electric windows can be used. This could result in serious injury.
- Never leave children or disabled people alone in the car. The doors could be locked with the remote control key and the occupants could become trapped in the vehicle. The vehicle occupants could be exposed to extremely high or low temperatures, depending on the time of year.
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 your 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.
