LX570_OM_OM60N01U_(U)4-2. Driving procedures
■Paddle shift switches (if equipped)
●When the “-” paddle shift switch is operated
in the D position, a shift range will be auto-
matically selected. The highest gear of the fi rst shift range will be one gear lower than
the gear in use during normal D position driving.
●Automatic deactivation of shift range selection in the D position
Shift range selection in the D position will be deactivated in the following situations:
• When the vehicle comes to a stop
• If the accelerator pedal is depressed for long er than a certain period of time in one
shift range
■Driving on a downhill
On declines, there may be case where the ve hicle shifts down automatically to obtain
engine braking. As a result of the down shifting, the engine speed may increase.
■Second start mode automatic deactivation
Second start mode is automatically deactivated if the engine is turned off after driving in
second start mode.
■S mode
When the shift range is 7 or lower, holding the shift lever toward “+” sets the shift range to
8.
■AI-SHIFT
AI-SHIFT automatically selects the suitable 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.)
■When driving with cruise control or dynamic radar cruise control activated
Even when performing the following actions with the intent of enabling engine braking,
engine braking will not activate because cruise control or radar cruise control will not be
canceled.
●While driving in D position (vehicles with paddle shift switches) or S mode, downshift-
ing to 7, 6, 5 or 4. ( P. 2 7 1 , 2 8 3 )
●When switching the driving mode to spor t mode while driving in D position. (P. 2 8 6 )
■If the shift lever cannot be shifted from P
P. 5 4 9
■If the “S” indicator does not come on ev en after shifting the shift lever to S
This may indicate a malfunction in the automatic transmission system. Have the vehicle
inspected by your Lexus dealer immediately.
(In this situation, the transmission will operat e in the same manner as when the shift lever
is in D.)
■Downshift restriction warning buzzer
To help ensure safety and driving performa nce, downshifting operation may sometimes
be restricted. In some circumstances, downshifting may not be possible even when the
shift lever is operated. (A buzzer will sound twice.)

■The center differential lock indicator light
The indicator light blinks while locking/unlocking the center differential.
■The center differential lock/unlock switch can be operated when
●The engine switch is in IGNITION ON mode.
●The vehicle speed is less than 62 mph (100 km/h).
■Locking/unlocking the center differential
●When the four-wheel drive control switch is in L4 with the center differential locked,
VSC is automatically turned off. (The center differential lock and VSC OFF indicator
lights come on.)
●If the operation is not completed, the center di fferential lock indicator blinks. If the indi-
cator light does not turn off when unlocking the center differential, drive straight ahead
while accelerating or decelerating, or drive in reverse.
●If the center differential lock/unlock is not completed within 5 seconds while the cruise
control system is on, cancel the cruise control system.
■If the low speed four-wheel drive indicator light or the center differential lock indicator
light blinks
●If the low speed four-wheel drive indicator lig ht continues to blink when using the four-
wheel drive control switch, stop the vehicle completely, move the shift lever to N and
operate the switch again.
●If the shift lever is moved before the low sp eed four-wheel drive indicator turns on/off,
the transfer mode may not be shifted comp letely. The transfer mode disengages both
the front and rear driveshafts from the powertrain and allows the vehicle to move
regardless of the shift position. (At this time , the indicator blinks and the buzzer sounds.)
Therefore, the vehicle is free to roll even if the automatic transmission is in P. You or
someone else could be seriously injured. You must complete the shifting of the transfer
mode.
To complete the shifting, stop the vehicle completely, return the shift lever to N, and
confirm that the shift was completed (the indicator turns on/off).
●If the engine coolant temperature is too low, the four-wheel drive control system may
not be able to shift. When the engine is warmer operate the switch again.
If the low speed four-wheel drive indicator light or the center differential lock indicator
light continues to blink even after attempti ng the above, there may be a malfunction in
the engine, the brake system or the four-wheel drive system. In this case, you may not be
able to shift between H4 and L4, and the center differential lock may not be operable.
Have the vehicle inspected by your Lexus dealer immediately.

■While driving
Never move the four-wheel drive control switch
if the wheels have lost traction. Doing
so may cause an accident resulting in death or serious injury.
■When the vehicle is parked
If the shift lever is moved before the low sp eed four-wheel drive indicator turns on/off,
the transfer mode may not be shifted completely. The transfer mode disengages both
the front and rear driveshafts from the powertrain and allows the vehicle to move
regardless of the shift position. (At this time, the indicator blinks and the buzzer
sounds.)
Therefore, the vehicle is free to roll even if the automatic transmission is in P. You or
someone else could be seriously injured. You must complete the shifting of the transfer
mode.
NOTICE
■To prevent damage to the center differential

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 accompan ied by vibration, and ultimately damage.
●Water can wash the grease from wheel be arings, causing rusting and premature fail-
ure, and may also enter the differentials, tr ansmission and transfer case, reducing 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 terr ain, sand, mud, or water. For scheduled maintenance
information, refer to the “Warranty and Services Guide”, “Owner’s Manual Supple-
ment” or “Scheduled Maintenance”.
