WARNING
When driving on slippery road surfaces
■
Do not accelerate or shift gears suddenly.
Sudden changes in engine braking may cause the vehicle to spin or skid, resulting in an
accident.
NOTICE
Hybrid battery (traction battery) charge
■
If the shift lever is in N, the hybrid battery (traction battery) will not be charged even
when the engine is running. Therefore, if the vehicle is left with the shift lever in N for a
long period of time, the hybrid battery (traction battery) will discharge, and this may
result in the vehicle not being able to start.
