1-30 In Brief
Maintenance
Always keep the tires properly
inflated and the vehicle properly
aligned.
The weight of excess cargo in the
vehicle affects efficiency and range.
Avoid carrying more than is needed.
If fuel is not regularly used, consider
keeping the fuel tank only one‐third
full. Excess fuel weight impacts
efficiency and range.
Use premium fuel.
Avoid unnecessary use of electrical
accessories. Power used for
functions other than propelling the
vehicle will reduce EV range.
Using a rooftop carrier will reduce
efficiency due to additional weight
and drag.Roadside Assistance
