Higher speedsuse more energy and can significantlyreduce electric range.Use cruise control when appropriate.Do not shift to N to coast. The vehiclerecovers energy while coasting andbraking in D or L.Efficiency gauge in the instrumentclusterThe ball indicator should be keptgreen and in the centre of the gauge.Inefficient acceleration is indicatedwhen the ball turns yellow and travelsabove the centre of the gauge.Aggressive braking is indicated whenthe ball turns yellow and travels belowthe centre of the gauge.Drive mode and gear mode selectionUse normal mode when possible.Sport mode provides moreresponsive acceleration than normalmode but can reduce efficiency.Use mountain mode prior to climbinglong, steep grades in mountainousareas. Be sure to engage mountainmode before starting to climb.Mountain mode reduces electricrange and power but may be neededto maintain speeds above 60 mphwhen climbing grades of 5 % orgreater.Use L in heavy stop‐and‐go traffic orwhen travelling downhill. L requiresless brake pedal application andprovides a controlled, efficient way toslow the vehicle down.
