CAUTION
■When starting the vehicle
Always keep your foot on the brake pedal while stopped with the engine running.
This prevents the vehicle from creeping.
■When driving the vehicle
●Do not drive if you are unfamiliar with the location of the brake and accelerator
pedals to avoid depressing the wrong pedal.
• Accidentally depressing the accelerator pedal instead of the brake pedal will
result in sudden acceleration that may le ad to an accident that could result in
death or serious injury.
• When backing up, you may twist your body around, leading to a difficulty in operating the pedals. Make sure to operate the pedals properly.
• Make sure to keep a correct driving posture even when moving the vehicle only slightly, allowing you to depress the brake and accelerator pedals prop-
erly.
• Depress the brake pedal using your right foot. Depressing the brake pedal using your left foot may delay response in an emergency, resulting in an acci-
dent.
●Do not drive the vehicle over or stop the vehicle near flammable materials.
The exhaust system and exhaust gases ca n be extremely hot. This may cause a
fire if there is any flammable material nearby.
●Do not let the vehicle roll backwards while the shift lever is in a driving position, or
roll forward while the shift lever is in “R”.
Doing so may cause the engine not to oper ate or lead to poor brake and steering
performance, resulting in an accident or damage to the vehicle.
●If the smell of exhaust is noticed inside the vehicle, open the windows and check
that the trunk is closed.
Large amounts of exhaust in the vehicle can cause driver drowsiness and an acci-
dent, resulting in death or a serious health hazard. Have the vehicle inspected by
your Lexus deal er immediately.
●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 automatic transmission and may
result in a loss of vehicle control.

■If the indicator does not come on even after shifting the shift lever to “S”
This may indicate a malfunction in the automatic 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”.)
■AI-SHIFT
The AI-SHIFT automatically shifts the gear to the optimal position according to the
driver’s input and driving conditions.
GS460: The AI-SHIFT automatically operates when the shift lever is in the “D” or
“S” position.
GS350: The AI-SHIFT automatically operat es when the shift lever is in the “D”
position. (Shifting the shift lever to the “S” position cancels the function.)
