2-1. Driving procedures

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 engine off while driving. 
The power steering and brake actuator (GS430) or brake booster (GS350) will
not operate properly if the engine is not running.
●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 2 )
●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.

2-1. Driving procedures

When driving
■Downshifting restrictions in “S” mode
The shift lever cannot be downshifted if the following speeds are exceeded. (The
w
arning buzzer will sound twice in this situation.)
The maximum speeds can get lower when the engine is not warm such as in cold
climates or before warm-up.
■When driving with the cruise control syst em (or dynamic radar cruise control sys-
tem)
The engine brake will not operate in the “S” mode, e
ven when downshifting to “5” or
“4”. ( P. 1 2 4 , 127 )
■Snow mode automatic deactivation
Snow mode is automatically deactivated if the e
ngine 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 8 4
■If the indicator does not come on even after shifting the shift lever to “S”
This may indicate a malfunction in the automatic transmission system. Have the
v
ehicle inspected by your Lexus dealer immediately. 
(In this situation, the vehicle will operate as if the shift lever is in “D”.)
■AI-SHIFT
The AI-SHIFT automatically shifts the gear to
the optimal position according to the
driver's input and driving conditions. 
The AI-SHIFT automatically operates when th e
shift lever is in the D position. (Shift-
ing the shift lever to the S position cancels the function.)
