CDifficulty 3/5

In a combustion-engine vehicle with electronic injection that does not require accelerator input to start, which practice avoids unnecessary fuel use when starting the engine?

Correct answer

Start without pressing the accelerator, following instructions.

Start without pressing the accelerator, following manufacturer instructions. Injection supplies the fuel needed to start; unnecessary revving does not save fuel. Before moving, meet vehicle checks and safety conditions, such as pneumatic brake pressure where fitted. Do not indiscriminately idle until the entire engine reaches normal operating temperature.
