WARNING
Never stop the engine before the vehicle has come to a complete stop. You can lose control of the vehicle, crash, and be seriously injured.
x The airbags and safety belt pretensioners will not work when the ignition is switched off.
x The brake booster does not work when the engine is not running. More brake pedal pressure will be needed to stop the vehicle.
x The power steering system does not work when the engine is not running, and you will need more force to steer the vehicle.
x When the key is removed from the ignition switch, the steering will lock and you will not be able to steer the vehicle.
NOTICE
If the vehicle has been driven hard for a long time, the engine could overheat when it is stopped. To reduce the risk of engine damage, let the engine idle in Neutral for about 2 minutes before you switch off the ignition.
If the ignition is switched on or the engine is running and the driver door is opened, a chime sounds. The chime is also a reminder to switch off the engine and turn off the ignition before leaving and locking the vehicle from the outside.
The vehicle key can only be removed from the ignition when the transmission is in Park (P).
After the engine has been switched off, the radiator fan in the engine compartment may keep running for several minutes, or may start running after the vehicle has been parked for a while, even if the ignition is switched off and the vehicle key has been removed. The radiator fan shuts off automatically when the engine has cooled down enough.
WARNING
High voltage systems in the engine compartment can cause electrical shocks or even electrocution, severe burns, other serious injuries, and even death!
x Never short-circuit the electrical system. Be especially careful when using jumper cables. The vehicle's battery could explode!
x To reduce the risk of electrical shock and personal injury while the engine is running or being started:
– Never touch ignition cables. Never touch other components of the high voltage electronic ignition system.
– Never touch the wiring of the HID – High Intensity Discharge (Xenon) headlights.
x Read and heed the important information and warnings on cleaning the engine
compartment ⇒ Cleaning the engine compartment.
WARNING
Moving parts in the engine compartment can cause serious personal injury on contact.
x Never reach into the area around or touch the radiator fan. Contact with the blades can cause serious personal injury. Always remember that the radiator fan is temperature-controlled and can come on suddenly even when the engine has been switched off for a while and the key has been removed from the ignition.
x If you have to perform a check or repair when the engine is running, there are more risks from the rotating parts, such as the drive belts, alternator, radiator fan, etc., and from the high-voltage ignition system. Always use extreme care.
– Always make sure that jewelry, loose clothing and long hair do not get caught in rotating engine parts. Before starting any work remove your jewelry, take off your necktie, tie back and cover your hair, and do not wear clothing that can hang down and get caught in moving engine parts.
– Always use extreme caution if the accelerator pedal has to be depressed to perform a check. The vehicle will start to move even if the parking brake is on.
x Never leave any objects in the engine compartment, for example cleaning rags and tools. Objects left behind can cause malfunctions, engine damage, and even fires.
WARNING
Operating fluids and some materials in the engine compartment can catch fire easily, causing burns and other serious personal injuries!
x Never smoke near the engine compartment.
x Never work next to open flames or sparks.
x Never pour or spill operating fluids or other flammable liquids on the engine. These fluids can ignite on hot engine parts and cause injuries.
x If work on the fuel system or the electrical system is necessary:
– Always disconnect the 12 Volt vehicle battery. Make sure the vehicle is unlocked when you disconnect the battery, or the alarm will go off. Never touch the electrical wiring of the ignition system.
– Never work near heaters, water heaters, or other open flames.
x Always have a functional, approved fire extinguisher nearby.
