Driving
CAUTION
Observe the following precautions.
Failure to do so may result in death or serious injury.
■When driving on slippery road surfaces
●Sudden braking, acceleration and steeri ng may cause tire slippage and reduce
your ability to control the vehicle.
●Sudden acceleration, engine braking due to shift changing, or changes in engine
speed could cause the vehicle to skid.
●After driving through a puddle, lightly depress the brake pedal to make sure that
the brakes are functioning properly. Wet brake pads may prevent the brakes from
functioning properly. If the brakes on only one side are wet and not functioning
properly, steering control may be affected.
■When shifting the shift lever
●Do not let the vehicle roll backward 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 to stall or lead to poor brake and steering perfor-
mance, resulting in an acciden t or damage to the vehicle.
●Do not shift the shift lever to P while the vehicle is moving.
Doing so can damage the transmission and may result in a loss of vehicle control.
●Do not shift the shift lever to R wh ile the vehicle is moving forward.
Doing so can damage the transmission and may result in a loss of vehicle control.
●Do not shift the shift lever to D while the vehicle is moving backward.
Doing so can damage the transmission and may result in a loss of vehicle control.
●Moving the shift lever to N while the vehicle is moving will disengage the engine
from the transmission. Engine braking is not available when N is selected.
●Be careful not to shift the shift lever wi th the accelerator pedal depressed. Shift-
ing the shift lever to a gear other than P or N may lead to unexpected rapid accel-
eration of the vehicle that may cause an accident and result in death or serious
injury.

4-1. Before driving
NOTICE
■When encountering flooded roads
Do not drive on a road that has flooded after heavy rain etc. Doing so may cause
the following serious damage to the vehicle:
●Engine stalling
●Short in electrical components
●Engine damage caused by water immersion
In the event that you drive on a flooded road and the vehicle is flooded, be sure to
have your Lexus dealer check the following:
●Brake function
●Changes in quantity and quality of oil and fluid used for the engine, transmission,
transfer (AWD models), differential, etc.
●Lubricant condition for the propeller shaft, bearings and suspension joints (where
possible), and the function of all joints, bearings, etc.

Automatic transmission
While the engine switch is in IGNITION ON mode, move the shift

Driving
To enter M mode, shift the shift lever to M. Gears can then be selected by
operating the shift lever or paddle shif t switches, allowing you to drive in
the gear of your choosing.
Upshifting
Downshifting
The gear changes once every time the
shift lever or paddle shift switch is
operated.
The selected gear, from M1 to M6, will
be fixed and displayed in the meter.
When in the M position, the gear will not change unless the shift lever
or paddle shift switches are operated.
However, even when in the M position, the gears will be automatically
changed in the following situation:
●When vehicle speed drops (downshift only).
●When the automatic transmission fluid or engine coolant tempera-
ture is low.
●When automatic transmission fluid temperature is high.
●When the needle of the tachometer is in the red zone (the range
which exceeds the allowable revs of the engine).

4-2. Driving procedures
In the following situations, the gear will not shift even if the shift lever or
paddle shift switches are operated.
●“1st Gear not available due to slippe ry road surface” is displayed on
the multi information display.
●The vehicle speed is low (upshift only).
■When the “-” paddle shift switch is operated in the D position
A shift range will be automatically selected. The highest gear of the first 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 “+” paddle shift switch is op erated when the shift range is in 5
●If the accelerator pedal is depressed for more than a certain period of time
●When the shift lever is shifted to other than D
■To protect automatic transmission
“Transmission Fluid High Temperature” is displayed 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 ve hicle inspected by your Lexus dealer.
■Downshifting restrictions warning buzzer
To help ensure safety and driving perfor mance, downshifting operation may some-
times be restricted. In some circumstances, downshifting may not be possible even
when the shift lever or paddle shift switch is operated. (A buzzer will sound twice.)
■Snow mode automatic deactivation
Snow mode is automatically deactivated if the engine switch is turned off after driv-
ing in snow mode.
■If the shift lever cannot be shifted from P
