When driving
CAUTION
■When driving the vehicle
●Do not under any circumstances shift the shift lever to “P”, “R” or “N” while the
vehicle is moving.
Doing so can cause significant damage to the transmission and may result in a
loss of vehicle control.
●Do not shift the shift lever to “N” while the vehicle is moving. 
Doing so may cause the engine brake not to operate properly and lead to an
accident.
●Do not turn the hybrid system off while driving. 
The brake actuator will not operate properly if the hybrid system is off.
●Use engine braking (downshift) to maintain a safe speed when driving down a
steep hill. 
Using the brakes continuously may cause the brakes to overheat and lose effec-
tiveness. ( P. 1 0 8 )
●When stopped on an inclined surface, use the brake pedal and parking brake to
prevent the vehicle from rolling backward or forward and causing an accident.
●Be careful when driving on slippery surfaces, as the vehicle may spin or skid when
downshifting, rapidly accelerating, braking or turning.
●Do not adjust the position of the steering wheel, the seat, or the inside or outside
rear view mirrors while driving. 
Doing so may result in a loss of vehicle control that can cause accidents that may
result in death or serious injury.
●Always check that all passengers' arms, heads or other parts of their bodies are
not outside the vehicle, as this may result in death or serious injury.

When driving
■When in heavy traffic
To avoid running the hybrid battery (traction battery) down, leave the shift lever in
“D” or “S”.
■When driving with the cruise control system (or dynamic radar cruise control sys-
tem)
The engine brake will not operate in the “S” mode, even when downshifting to “5” or
“4”. ( P. 129, 132)
■Snow mode automatic deactivation
Snow mode is automatically deactivated if the power switch is turned to “ACC” or
“IG-ON” mode after driving in snow mode.
■If the shift lever cannot be shifted from “P”
 P. 4 7 2
■If the indicator does not come on even after shifting the shift lever to “S”
This may indicate a malfunction in the transmission. Have the vehicle inspected by
your Lexus dealer immediately. 
(In this situation, the vehicle will operate as if the shift lever is in “D”.)
