Driving
Precautions While Driving
Avoid driving in deep water and on flooded roads. This can damage the power
system or driveline, or caus e electrical component failure.
The vehicle is equipped with ultra high pe rformance summer tires that, due to their
decreased tread depth, are at greater risk of hydroplaning on wet roads compared
to regular tires. Exercise caut ion when driving on wet surfaces.
The vehicle is equipped with ultra high performance summer tires. These tires are
designed for optimum performance and handling in warm climates, and are not
suitable for below freezing, snowy or ic y weather conditions. If you drive under
these circumstances, use of winter tire s is recommended and may be mandatory,
depending on your region, province or territory.
2 Winter Tires P. 419
2 Cold Weather Driving P. 420
Due to limitations of the Lithium-ion Hi gh Voltage battery, the minimum starting
temperature for the vehicle is -4°F (-20°C).
Inability to start the vehicle and/or decrease d performance is expected if the vehicle
is operated at temperatures below -4°F (-20°C).
■In Rain
■In Snow and Ice
1 Precautions While Driving
NOTICE
Do not select a shift button while pressing the
accelerator pedal.
NOTICE
The following can damage the under spoiler, under
covers, front bumper, rear diffuser, brake cooling
components, and side sill:
•Parking the vehicle by a parking block•Parallel pa rking along the road shoulder•Driving toward the bottom of a hill•Driving up or down to a different surface level
(such as a road shoulder)
•Driving on a rutted or bumpy road•Driving on a road with potholes•Driving over speed bump
NOTICE
If you repeatedly turn the steering wheel at an
extremely low speed, or hold the steering wheel in
the full left or right position for a while, the electric
power steering (EPS) system heats up. The system
goes into a protective mode, and limits its
performance. The steering wheel becomes harder
and harder to operate. Once the system cools down,
the EPS system is restored.
Repeated operation under these conditions can
eventually damage the system.
If the power mode is set to ACCESSORY while
driving, the power system will shut down and all
steering and brake power a ssist functions will stop,
making it difficult to control the vehicle.
Driving in snow or icy c onditions may accumulate ice
on the brake disk surface, reducing br aking power.
