Subaru Crosstrek Owners Manual: General precautions when starting/stopping engine

WARNING

• Never start the engine from outside the vehicle (except when using the remote engine start system). It may result in an accident.
• Do not leave the engine running in locations with poor ventilation, such as a garage and indoors.

  The exhaust gas may enter the vehicle or indoors, and it may result in carbon monoxide poisoning.

• Do not start the engine near dry foliage, paper, or other flammable substances. The exhaust pipe and exhaust emissions can create a fire hazard at high temperatures.

CAUTION

• If the engine is stopped during driving, the catalyst may overheat and burn.
• When starting the engine, be sure to sit in the driver's seat (except when using the remote engine start system).

NOTE

• Avoid rapid racing and rapid acceleration immediately after the engine has started
• For a short time after the engine has started, the engine speed is kept high.

  When the warm-up is completed, the engine speed lowers automatically.

• On rare occasions, it may be difficult to start the engine depending on the fuel and the usage condition (repeated driving of a distance in which the engine has not warmed up sufficiently).

  In such a case, it is recommended that you change to a different brand of fuel.

• On rare occasions, transient knocking may be heard from the engine when the accelerator is operated rapidly such as a rapid start-up and a rapid acceleration. This is not a malfunction.
• The engine starts more easily when the headlights, air conditioner and rear window defogger are turned off.
