Driving Your Vehicle
Hydroplaning
If the road is wet enough and you are 
going fast enough, your vehicle may 
have little or no contact with the road 
surface and actually ride on the water. 
The best advice is SLOW DOWN when 
the road is wet.
The risk of hydroplaning increases as 
the depth of tire tread decreases, refer 
to “Tire Tread” section in chapter 9.
Driving in Flooded Areas
Avoid driving through flooded areas 
unless you are sure the water is no 
higher than the bottom of the wheel hub. 
Drive through any water slowly. Allow 
adequate stopping distance because 
brake performance may be reduced.
After driving through water, dry the 
brakes by gently applying them several 
times while the vehicle is moving slowly.
Highway Driving
Tires
Adjust the tire inflation, as specified. 
Under-inflation may overheat or damage 
the tires.
Do not install worn-out or damaged tires, 
which may reduce traction or fail the 
braking operation.
 Information
Never over-inflate your tires above the 
maximum inflation pressure, as specified 
on your tires.
Coolant and high voltage battery
Driving at higher speeds on the highway 
consumes more electric energy and is 
less efficient than driving at a slower, 
more moderate speed. Maintain a 
moderate speed in order to conserve 
electric energy when driving on the 
highway.
Be sure to check both the coolant level 
and the electric energy level before 
driving.
