When you enter the vehicle carrying a sm art key and push
the ignition switch, the electronic code in the key is
automatically checked as to whether it corresponds to the
registered ID code for the vehicle. The key indicator light
comes on, the steering column lock is released, and the
engine immobilizer system is cancelled.
At this time, the security indicator light goes off and you can
start the engine when you turn the ignition switch and the key
indicator light does not come on. When you turn the ignition
switch, turn it slowly and surely. If you turn it quickly, it may
become stuck. To free it, see the following “If the ignition switch
seems to be stuck”.
If you push the ignition switch when the smart key is not within
the effective range of the smart key system, a warning tone
sounds and “Key is not Detected” appears on the display. If the ignition switch seems to be stuck:
To free the ignition switch, perform the following:

2. Be sure to push the ignition switch while turning the
steering wheel slightly in either direction, and then turn
the switch.

STARTING AND DRIVING
300“START” Starter motor on. The ignition switch will
return to the “ON” position when released.
For starting tips, see page 304.
“ON” Engine on and all accessories on.
This is the normal driving position.
NOTICE
Do not leave the ignition switch in the “ON” position if
the engine is not running. The battery will discharge
and the electronic ignition system could be damaged.
“ACC” Accessories such as the radio operate, but the
engine is off.
31L347
“LOCK” Engine is off and the steering wheel is locked.
When
you leave your vehicle, be sure to turn the ignition switch
to the “LOCK” position and carry the smart key.
 If you open the driver’s door without returning the ignition
switch to the “LOCK” position, beeps keep sounding while
the door is opened.
 If you close a door to leave your vehicle while carrying a key
on which the ignition switch has not been returned to the
“LOCK” position, “Key is not Detected” appears on the
multi−information display, a warning tone sounds inside and
beeps sound outside.
 If the selector lever is in a position other than “P”, you cannot
turn the ignition switch to the “LOCK” position. At this time,
when you open the driver’s door and are going to get out of
the vehicle, “Shift to P Range” appears on the
multi−information display and a warning tone sounds inside.

STARTING AND DRIVING

The shift position or shift range position is displayed
on the instrument cluster.
P: Parking, engine starting and key removal position
R: Reverse position
N: Neutral position
D: Normal driving position (Shifting into overdrive
possible)
S: “S” mode driving
+: Upshifting
–: Downshifting Correct
use of the automatic transmission is explained in
the following parts.
(a) Normal driving
(b) Driving in “S” mode
(c) Using engine braking
(d) Backing up
(e) Parking
(f) Good driving practice

3“S” mode position
4Shift range position indicator
You can change the shift range position in the “S” mode.
The shift range position can be switched between “6”
(sixth range) and “1” (first range) by moving the selector
lever up to the “+” side or down to the “–” side. The first
shift range position is “5” (fifth range) when the selector
lever is shifted to the “S” position.
However, if you move the lever to the “S” position in AI
shifting control, “5” (fifth range), “4” (fourth range) or “3”\
(third range) will be the first shift range. This is because
the suitable shift range is selected depending on the
driving condition.
31L328
 Shift range position indicator
The shift range position is displayed on the instrument cluster.
 Shift range positions
“6” (sixth range): The most suitable gear is automatically
selected between first and overdrive (sixth) gears according
to vehicle speed and driving conditions. Always use the “6”
(sixth range) position to improve fuel economy and for quiet
driving.
“5” (fifth range): The most suitable gear is automatically
selected between first and fifth gears according to vehicle
speed and driving conditions. This range is suitable for
acceleration such as when you want to pass a vehicle
running ahead of you during high speed driving.

STARTING AND DRIVING
316In the power mode, the “ECT PWR” light in the instrument
cluster is on and the transmission is shifted up at higher vehicle
speeds and shifted down more responsively
than in the normal
mode.
To return to the normal mode, push the driving pattern selector
switch lightly on the “SNOW” side.
Snow mode: For slippery road surfaces such as in snow. In
this mode, the spinning of the rear wheels is controlled
appropriately.
When you push the driving pattern selector switch on the
“SNOW” side, the snow mode is turned on and the “ECT
SNOW” light in the instrument cluster comes on.
To return to the normal mode, push the driving pattern selector
switch on the “SNOW” side again.
When you turn the ignition switch off in the snow mode, the
mode automatically changes to the normal mode.
LEXUS PARK ASSIST SYSTEM
31L354b
 Sensors
The Lexus park assist system will help you to easily park
by detecting any obstacle around your vehicle with
ultrasonic sensors and informing you of the approximate
distance from the vehicle to the obstacle with the
indicators on the display and with beeping sounds.*
This system will operate at a vehicle speed of less than about
10 km/h (6 mph) with the selector lever in a position other than
“P”.
NOTE:
* The volume of the beeps can be changed.
Ask your Lexus dealer for details.

31L340
You can use this system in either of the following ways.
Push the main switch of the Lexus park assist system with
the ignition on. A beep sounds for one second. After the
system self− check is performed, the Lexus park assist
system screen appears for 2 seconds.
 Push the main switch of the Lexus park assist system and
turn the ignition on. The Lexus park assist system screen
appears for 2 seconds and a system self −check is
performed. At this time, a beep does not sound.
If an error is detected in the Lexus park assist system while
self−checking, beeps sound and the message appears in the
multi− information display. For details, see “Lexus park assist
system failure warning” on page 319. Up to 4 indicator bars are shown on the front and rear sides of
the vehicle mark and up to 3 indicator arcs are shown on each
corner of the vehicle mark. The number of indicators shows
the approximate range up to the obstacle. The indicator marks
disappear one
−by−one as your vehicle comes closer to the
obstacle. Also, as you get closer to the obstacle, the beeping
interval becomes shorter.
To turn off the system, push the main switch again.
NOTICE
 If an accident should occur, the sensors will be
affected, resulting in a system failure.
 If the indicators remain on the display but you do not
hear a beeping sound, the system may be
malfunctioning. Contact your Lexus dealer.

Lexus park assist system failure warning
31L351
The system self check is automatically performed when
the Lexus park assist system is turned on. At this time if
an error is detected, the master warning light comes on
accompanied by 5 beeps, the faulty sensor blinks and
either of the following messages appear in the
multiinformation display.
 “Check Park Sonar”
 “Clean Park Sonar”
The sensors operate individually. When one sensor is
malfunctioning, you will notice sounding beeps and blinking
indicators to show that it is malfunctioning. If another sensor
detects an obstacle during this time, the approximate distance
to the obstacle will be shown by that sensor.
