2-1. Driving procedures
NOTICE
nTo prevent battery discharge
lDo not leave the “ENGINE START STOP” switch in ACCESSORY or IGNI-
TION ON mode for long periods of time without the engine running.
lIf the indicator on the “ENGINE START STOP” switch is illuminated, the
“ENGINE START STOP” switch is not off. When exiting the vehicle, always
check that the “ENGINE START STOP” switch is off.
lDo not stop the engine when the shift lever is in a position other than P. If the
engine is stopped in another shift lever position, the “ENGINE START STOP”
switch will not be turned off but instead be turned to ACCESSORY mode. If the
vehicle is left in ACCESSORY mode, battery discharge may occur.
nWhen starting the engine
lDo not race a cold engine.
lIf the engine becomes difficult to start or stalls frequently, have the engine
checked immediately.
nSymptoms indicating a malfunction with the “ENGINE START STOP” switch
If the “ENGINE START STOP” seems to be operating somewhat differently than
usual, such as the switch sticking slightly, there may be a malfunction. Contact your
Lexus dealer immediately.

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.)

CAUTION
nIf a safety system warning light does not come on
Should a safety system light such as the ABS and SRS airbag warning light not
come on when you start the engine, this could mean that these systems are not
available to help protect you in an accident, which could result in death or serious
injury. Have the vehicle inspected by your Lexus dealer immediately if this occurs.

cle’s systems. (→P. 535)

or if the lights do not turn off. Have the vehicle inspected by your Lexus
dealer, for details.
