Extended Range

These two symbols are associated with electric vehicles (EVs) as power saving mode indicators. Both will most likely appear in gray scale in the vehicle’s instrument panel information center. They are effectively Extended Range EV Mode Indicators.

• But first, is one of these truly your symbol?? If yes, then continue on below.
• Otherwise return to our main Picture Symbols page and scan again!

The first symbol is a Hold Mode Indicator.  Its appearance is that of a locked household battery. It is intended for use when a trip is expected to use all of the high-voltage battery’s charge. Using Hold Mode at higher, highway speeds maximizes both EV miles and fuel efficiency.

The second is the Mountain Mode indicator. It also appears as a household battery, but overlain by mountains.  It is used when steep grades or mountainous terrain are expected. The mode maintains a reserve electrical charge of the high voltage battery to provide better grade climbing performance, but the vehicle will have less responsive acceleration. Select Mountain Mode at least 20 minutes before driving on steep grades to allow time to build a sufficient battery charge reserve.

Maximum Power

Finally, this is a Wide Open Watts indicator symbol. This mode is used for short durations to provide maximum propulsion torque for maximum acceleration. It will not function when
the vehicle battery is low and will greatly reduce the vehicle’s range.

If the appearance of any indicator is unexpected, it is likely that the Mode selector has been pressed inadvertently.

Remember that only proper service and repair procedures will ensure the safe and reliable operation of your car. In addition, proper safety procedures and precautions, such as the  use of safety goggles, the right tools and the equipment should be followed at all times to eliminate the possibility of personal injury or improper service which could damage the vehicle or compromise its safety.

Technology is always changing and what is current and accurate today may be literally out-of-date and inaccurate tomorrow. And when it comes to the current state of flux in the auto industry, nothing is more true.
