Automatic transmission
Select a shift position appropriate for the driving conditions.

the vehicle is completely stopped.

2-1. Driving procedures
GX460_U.S.A. (OM60J00U)
■S mode
When the shift range is 5 or lower, holding the shift lever toward “+” sets the shift
range to 6.
■AI-SHIFT
AI-SHIFT automatically selects the optimal gear according to driver performance
and driving conditions.
AI-SHIFT automatically operates when the shift lever is in the D position. (Shifting
the shift lever to the S position cancels the function.)
The engine speed remain high after releasing the accelerator pedal. This does not
indicate a malfunction.
■When driving with the cruise control or dynamic radar cruise control
Engine braking will not occur in S mode, even when downshifting to 5 or 4.
( → P. 246, 250)
■If the shift lever cannot be shifted from P
→ P. 7 3 7
■If the “S” 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
vehicle inspected by Lexus dealer immediately.
(In this situation, the transmission will operate in the same manner as when the shift
lever is in D.)
■Downshift restriction warning buzzer (S mode)
To help ensure safety and driving performance, downshifting operation may some-
times be restricted. In some circumstances, downshifting may not be possible even
when the shift lever is operated. (A buzzer will sound twice.)

■If the automatic transmission system overheats
The system will cease operation, a buzzer will sound and a warning message will be
displayed to alert the driver. Stop the vehicle in a safe place until the warning mes-
sage turns off. (→P. 700)
■Sounds and vibrations caused by the Crawl Control system
●A sound may be heard from the engine compartment when the engine is
started or just after the vehicle begins to move. This sound does not indicate that
a malfunction has occurred in Crawl Control system.
●Either of the following conditions may occur when the Crawl Control system is
operating. None of these are indicators that a malfunction has occurred.
• Vibrations may be felt through the vehicle body and steering.
• A motor sound may be heard after the vehicle comes to a stop.
■If the slip indicator comes on...
It may indicate a malfunction in the system. Consult your Lexus dealer.
CAUTION
■When using Crawl Control
Do not rely solely on the Crawl Control. This function does not extend the vehicle’s
performance limitations. Always thoroughly check the road conditions, and drive
safely.
■These conditions may cause the system not to operate properly
When driving on the following surfaces, the system may not be able to maintain a
fixed low speed, which may result in an accident:
●Extremely steep inclines.
●Extremely uneven surfaces.
●Snow-covered roads, or other slippery surfaces.

NOTICE
■To prevent the water damage
Take all necessary safety measures to ensure that water damage to the engine or
other components does not occur.
●Water entering the engine air intake will cause severe engine damage.
●Water entering the automatic transmission will cause deterioration in shift quality,
locking up of your transmission accompanied by vibration, and ultimately dam-
age.
●Water can wash the grease from wheel bearings, causing rusting and premature
failure, and may also enter the differentials, transmission and transfer case, reduc-
ing the gear oil’s lubricating qualities.
■When you drive through water
If driving through water, such as when crossing shallow streams, first check the
depth of the water and the bottom of the riverbed for firmness. Drive slowly and
avoid deep water.
■Inspection after off-road driving
●Sand and mud that has accumulated in brake drums and around brake discs may
affect braking efficiency and may damage brake system components.
●Always perform a maintenance inspection after each day of off-road driving that
has taken you through rough terrain, sand, mud, or water. For scheduled mainte-
nance information, refer to the “Warranty and Services Guide”, “Owner’s Manual
Supplement” or “Scheduled Maintenance”.
