When driving
Automatic transmission
Select a shift position appropriate for the driving conditions.
nShifting the shift lever
While the “ENGINE START STOP” switch is in IGNITION
ON mode, depress the brake pedal and move the shift lever.
nShift position purpose
*1:Shifting to the D position allows the system to select a gear suitable for the
driving conditions. Setting the shift lever to the D position is recommended
for normal driving.
*2: Selecting shift ranges using S mode restricts the upper limit of the possible
gear ranges, controls engine braking forces, and prevents unnecessary
upshifting.

2-1. Driving procedures
nSnow mode automatic deactivation
Snow mode is automatically deactivated if the “ENGINE START STOP” switch is
turned off after driving in snow mode.
nS mode
lWhen the shift range is “5” or lower, holding the shift lever toward “+” sets the
shift range to “6”.
lTo prevent the engine from over-revving, upshifting may automatically occur.
lTo protect the automatic transmission, a function is adopted that automatically
selects a higher shift range when the fluid temperature is high.
nAI-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.)
nWhen 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. 204, 208)
nIf the shift lever cannot be shifted from P
→P. 5 7 9
nIf S 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 your Lexus dealer immediately.
(In this situation, the transmission will operate in the same as manner as when the
shift lever is in D.)
nDownshift 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. (The buzzer will sound twice.)

When driving
CAUTION
nOff-road driving precautions
Always observe the following precautions to minimize the risk of death or serious
injury or damage to your vehicle:
lDrive carefully when off the road. Do not take unnecessary risks by driving in
dangerous places.
lDo not grip the steering wheel spokes when driving off-road. A bad bump could
jerk the wheel and injure your hands. Keep both hands and especially your
thumbs on the outside of the rim.
lAlways check your brakes for effectiveness immediately after driving in sand,
mud, water or snow.
lAfter driving through tall grass, mud, rock, sand, water, etc., check that there is no
grass, bush, paper, rags, stone, sand, etc. adhering or trapped to the underbody.
Clear off any such matter from the underbody. If the vehicle is used with these
materials trapped or adhering to the underbody, a breakdown or fire could occur.
lWhen driving off-road or in rugged terrain, do not drive at excessive speeds,
jump, make sharp turns, strike objects, etc. This may cause loss of control or vehi-
cle rollover causing death or serious injury. You are also risking expensive dam-
age to your vehicle’s suspension and chassis.
NOTICE
nTo prevent water damage
Take all necessary safety measures to ensure that water damage to the engine or
other components does not occur.
lWater entering the engine air intake will cause severe engine damage.
lWater entering the automatic transmission will cause deterioration in shift quality,
locking up of your transmission accompanied by vibration, and ultimately dam-
age.
lWater 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.
