STARTING AND DRIVING
381
Using the electric motor in city
driving
A number of factors affect the electric motor's
driving range.
The driver can affect some of these factors while
others depend on outside conditions such as
temperature, road surface, etc.
Factors that determine the electric
motor's driving range
Factors outside of the driver's control
The following are examples of factors that the
driver cannot control:
•
The current traffic situation
•
Driving short distances
•
Topography
•
Ambient temperature and headwinds
•
Road conditions/road surface
The following table shows the
approximate
rela-
tionship between ambient temperature and driv-
ing range using the electric motor (with reduced
climate system functionality). Warmer tempera-
tures increase driving range.

Factors in the driver's control
The driver should be aware of the following fac-
tors in order to utilize the vehicle's electric motor
most efficiently:
•
Charge the hybrid battery regularly
•
Preconditioning
•
The
Pure
drive mode
•
Climate system settings
•
Speed and acceleration
•
The
Save
drive mode
•
Tires and inflation pressure
The following table shows the
approximate
rela-
tionship between constant speed and driving
range where driving at a lower constant speed
helps increase the electric motor's driving range.
62 mph (100 km/h) 70%
55 mph (90 km/h) 80%
50 mph(80 km/h) 90%
43 mph (70 km/h) 100%
37 mph (60 km/h) 110%
30 mph(50 km/h) 120%
NOTE
•
The figures in the preceding tables per-
tain to a new vehicle.
•
None of the figures are absolute and are
affected by e.g., driving style, weather,
traffic conditions, etc.
Driving with the electric motor
Use the
Pure
drive mode for the most energy-
efficient driving to help maximize driving range
using the electric motor only.
Use the
Save
drive mode for higher speeds
when driving farther than is possible using the
electric motor only.
