This is quite normal, and no cause for concern.

Glow plug system for the diesel engine
To avoid unnecessary load on the battery, do not use any other major electrical equipment while the glow plugs are pre-heating.

Start the engine as soon as the glow plug warning lamp goes out.

Starting the engine after the fuel tank has been completely run dry
If the fuel tank has been completely run dry, it may take longer than normal (up to one minute) to start the engine after refuelling with diesel fuel. This is because the system must eliminate air first.

WARNING

• Never start or run the engine in unventilated or closed rooms. The exhaust fumes contain carbon monoxide, an odourless and colourless poisonous gas. Risk of fatal accidents. Carbon monoxide can cause loss of consciousness. It can also cause death.
• Never leave the vehicle unattended if the engine is running.
• Never use “cold start sprays”, they could explode or cause the engine to run at high revs. Risk of injury.

Caution
• When the engine is cold, you should avoid high engine speeds, driving at full throttle and over-loading the engine. Risk of engine damage.
• The vehicle should not be pushed or towed for more than approximately 50 metres to start the engine. Fuel could enter the catalytic converter and damage it.
• Before attempting to push-start or tow a vehicle to start it, you should first try to start it using the battery of another vehicle. Note and follow the instructions  “Jump-starting”.

For the sake of the environment
Do not warm up the engine by running the engine with the vehicle stationary.

You should drive off as soon as you start the engine. This helps the engine reach operating temperature faster and reduces emissions.
