WARNING
■Stopping the engine in an emergency
If you want to stop the engine in an emer-
gency while driving the vehicle, press
and hold the engine switch for more than
2 seconds, or press it briefly 3 times or
more in succession. ( P.328)
However, do not touch the engine switch
while driving except in an emergency.
Turning the engine of f while driving will
not cause loss of steering or braking con-
trol, but the power assist to these systems
will be lost. This will make it more difficult
to steer and brake, so you should pull
over and stop the vehicle as soon as it is
safe to do so.
■When parking
Exhaust gases include harmful carbon
monoxide (CO), which is colorless and
odorless. Observe the following precau-
tions.
Failure to do so may cause exhaust gases
to enter the vehicle and may lead to an
accident caused by light-headedness, or
may lead to death or a serious health
hazard.
●If the vehicle is in a poorly ventilated
area or a closed area, such as a
garage, stop the engine.
●Do not leave the vehicle with the
engine running for a long time. If such
a situation cannot be avoided, park the
vehicle in an open space and ensure
that exhaust fumes do not enter the
vehicle interior.
●Do not leave the engine running in an
area with snow build-up, or where it is
snowing. If snowbanks build up around
the vehicle while the engine is running,
exhaust gases may collect and enter
the vehicle.

However, this function cannot entirely pre-
vent battery discharge. Do not leave the
vehicle with the engine switch in ACCES-
SORY or IGNITION ON mode for long
periods of time when the engine is not run-
ning.
If the engine is stopped with the shift
lever in a position other than P, the
engine switch will not be turned off but
instead be turned to ACCESSORY
mode. Perform the following proce-
dure to turn the switch off:

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.
●8-speed models: While driving in the D
position, downshifting to 7, 6, 5 or 4.
(  P.192)
●6-speed models: While driving in the D
position, downshifting to 5 or 4.

To drive using temporary shift range
selection, operate the “-” or “+” paddle
shift switch.
When the “-” paddle shift switch is
operated, the shift range will be down-
shifted to a range that enables engine
braking force that is suitable to driving
conditions.
When the “+” paddle shift switch is
operated, the shift range will be one
gear higher than the gear in use during normal D position driving.
Changing the shift range allows
restriction of the highest gear, prevent-
ing unnecessary upshifting and
enabling the level of engine braking
force to be selected.
