SPORT+ mode optimizes dynamic response
from all powertrain an d chassis systems -
perfect for your favorite winding road.
• EV operation is elimin ated while operating
in SPORT+ .
TRACK mode gives maximum, consistent
performance from dyna mic systems during
track day lapping sessions. Hybrid battery
charge is maintained for consistent
performance.
• VSA ® OFF indicator is illuminated in TRACK
mode indicating reduced stability control.
This allows more body side slip and wheel
spin before VSA ® begins to operate.
• Integrated Dynamics switch must be turned
and held to the right for several seconds to
engage TRACK mode.

Before choosing the TRACK mode, carefully read the
information about high performance driving.

During TRACK mode, the climate control system may
weaken its function to pr ioritize cooling the High
Voltage battery.

uuChecking and Maintaining Tires uDOT Tire Quality Grading (U.S. Vehicles)
Maintenance
DOT Tire Quality Grading (U.S. Vehicles)
The tires on your vehicle meet all U.S. Federal Safety
Requirements. All tires are also graded for treadwear, traction,
and temperature performance a ccording to Department of
Transportation (DOT) standards. The following explains these
gradings.
Quality grades can be found where applicable on the tire sidewall
between tread shoulder an d maximum section width.
The treadwear grade is a comparative rating based on the wear
rate of the tire when tested un der controlled conditions on a
specified government test course. For example, a tire graded 150
would wear one and one-half (1 1/2) times as well on the
government course as a tire grad ed 100. The relative performance
of tires depends upon the actual co nditions of their use, however,
and may depart significantly from the norm due to variations in
driving habits, service practices and differences in road
characteristics and climate.
■Uniform Tire Quality Grading
■Treadwear
1 Uniform Tire Quality Grading
For example:
Treadwear 200
Traction AA
Temperature A
All passenger car tires must conform
to Federal Safety Requirements in
addition to these grades.

Climate Control System Maintenance
Air Conditioning
To ensure proper and safe operation, the Society of Automotive Engineers (SAE
J2845) recommends that the refrigerant system only be serviced by trained and
certified technicians.
Never repair or replace the air conditio ning evaporator (cooling coil) with one
removed from a used or salvaged vehicle.
New replacement mobile air conditioning evaporators must be certified (and
labeled) as meeting SAE Standard J2842.
Dust and Pollen Filters
The climate control system is equipped wi th dust and pollen filters that collect
pollen, dust, and other debris in the air. The Maintenance MinderTM messages will let
you know when to replace the filters.
We recommend that you replace the dust an d pollen filters sooner when using your
vehicle in areas with high concentrations of dust.
1 Air Conditioning
NOTICE
Vented refrigerant is harmful to the environmentM
To avoid refrigerant from venting, never replace the
evaporator with one re moved from a used or
salvaged vehicleM
