*1: To improve fuel efficiency and reduce
noise, shift the shift lever to D for normal
driving.
You can choose gear range suitable for
your driving situation by operating the
paddle shift switches.
*2: Any gear range can be fixed when driv-ing in M mode.
■To protect the automatic transmission
“Transmission Fluid Temp High See
Owner’s Manual” is di splayed on the multi-
information display and a function is
adopted that automatically selects a higher
shift range when the fluid temperature is
high. Have the vehicle inspected by your
Lexus dealer.
■When driving with dynamic radar cruise
control with full-speed range activated
Even when performing the following
actions with the intent of enabling engine
braking, engine braking will not activate
because dynamic radar cruise control with
full-speed range will not be canceled.

D to R, N to R, P to D, or P to R (D
includes M) with the accelerator pedal
depressed, a warning message appears
on the multi-information display. If a
warning message is shown on the multi-
information display, read the message
and follow the instructions.
●When the accelerator pedal is depressed
too much while the vehicle is in reverse.

function for power train control, chassis
control or air conditioning operations.
2Eco mode
In contrast to Normal mode when stepping
on the accelerator pedal, torque genera-
tion becomes slower, air conditioning
operations (heating/cooling) are
restrained, and driving is suited for
improved fuel consumption.
When not in Eco mode and the driving
mode select switch is turned to the left,
“Eco” indicator will be shown on the multi-
information display.

restrict travel.
 Stay on established roads. When
conditions are we t, driving tech-
niques should be changed or travel
delayed to prevent damage to
roads.
■Additional informatio n for off-road driv-
ing
For owners in U.S. mainland, Hawaii and
Puerto Rico:
To obtain additional information pertaining
to driving your vehicle off-road, consult the
following organizations.
●State and Local Parks and Recreation
Departments
●State Motor Vehicle Bureau
●Recreational Vehicle Clubs
●U.S. Forest Service and Bureau of Land
Management
WARNING
■Off-road driving precautions
Always observe the following precau-
tions to minimize the risk of death or seri-
ous injury or damage to your vehicle:
●Drive carefully when off the road. Do
not take unnecessary risks by driving in
dangerous places.
●Do 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.
●Always check your brakes for effec-
tiveness immediately after driving in
sand, mud, water or snow.
●After driving through tall grass, mud,
rock, sand, water, et c., check that there
is no grass, bush, paper, rags, stone,
sand, etc. adhering or trapped to the
underbody. Clear of f any such matter
from the underbody. If the vehicle is
used with these materials trapped or
adhering to the underbody, a break-
down or fire could occur.
●When 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 vehicle rollover causing
death or serious injury. You are also
risking expensive damage to your
vehicle’s suspension and chassis.
NOTICE
■To prevent 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 trans-
mission will cause deterioration in shift
quality, locking up of your transmission
accompanied by vibration, and ulti-
mately damage.
●Water can wash the grease from wheel
bearings, causing rusting and prema-
ture failure, and may also enter the dif-
ferentials, transmission 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.
