4-2. Driving procedures
Driving
*1
: Shifting to the D position allows the sys-
tem to select a gear suitable for the
driving conditions. Setting the shift lever
to the D position is recommended for
normal driving.
*2
: Selecting gear steps using the M posi-
tion achieves suitable engine braking
forces by operating the shift lever or
paddle shift switches.
Q Driving on a downhill
On declines, there may be case where the
vehicle shifts down automatically to obtain
engine braking. As a result of the down-
shifting, the engine speed may increase.
Q To protect the automatic transmission
O If the tires spin continually when the vehi-
cle becomes stuck in mud, dirt or snow,
or if the accelerator pedal is depressed
and released repeatedly while driving,
the automatic transmission temperature
may become too high and the automatic
transmission may be damaged.
To avoid damaging the automatic trans-
mission, the system may temporarily lock
the gear.
If the automatic transmission tempera-
ture falls, the gear locking is canceled
and the automatic transmission is
returned to the normal operation.
O If the automatic transmission fluid tem-
perature is high, “Transmission Oil Temp.
High Stop in a safe place and See
owner’s manual” will be displayed on the
multi-information display. Immediately
stop the vehicle in a safe place, shift the
shift lever to P and wait until the warning
message goes off. If the warning message
goes off, you may start the vehicle again.
If the warning message do not go off,
contact your Lexus dealer.
Q When driving with dynamic radar cruise
control with full-speed range, dynamic
radar cruise control or cruise control
activated
Even when switching the driving mode to
SPORT S mode or SPORT S+ mode while
driving in D position (oP.407) with the
intent of enabling engine braking, engine
braking will not activate because dynamic
radar cruise control with full-speed range,
dynamic radar cruise control or cruise con-
trol will not be canceled.
Q Restraining sudden start (Drive-Start
Control)
oP.219
Q AI-SHIFT
The AI-SHIFT automatically selects the suit-
able gear according to driver performance
and driving conditions.
The AI-SHIFT automatically operates when
the shift lever is in D position. (Shifting the
shift lever to the M position cancels the
function.)
Select the shift position depending
on your purpose and situation.
