2344-5. Using the driving support systems
■When the 12-volt battery is discon-
nected (vehicles with VGRS)
The steering wheel may move from its 
straight forward position, but this will be 
corrected automatically when driving.
■Sounds and vibrations caused by the 
ABS, brake assist, VS C, TRAC, hill-start 
assist control and VGRS systems
●A sound may be heard from the engine 
compartment when the brake pedal is 
depressed repeatedly, when the engine is 
started or just after the vehicle begins to 
move. This sound does not indicate that a 
malfunction has occurred in any of these 
systems.
●Any of the following conditions may 
occur when the above systems are oper-
ating. None of these indicates that a mal-
function has occurred.
• Vibrations may be felt through the vehicle  body and steering.
• A motor sound may be heard after the 
vehicle comes to a stop.
■ECB operating sound
ECB operating sound may be heard in the 
following cases, but it  does not indicate that 
a malfunction has occurred.
●Operating sound heard from the engine 
compartment when the brake pedal is 
operated.
●Motor sound of the brake system heard 
from the front part of the vehicle when 
the driver’s door is opened.
●Operating sound heard from the engine 
compartment when one or two minutes 
passed after the stop of the engine 
■EPS, VGRS and DRS operation sound
When the steering wheel is operated, a 
motor sound (whirring sound) may be 
heard. This does not indicate a malfunction.
■Automatic reactivation of TRAC and 
VSC systems
After turning the TRAC and VSC systems 
off, the systems will be automatically re-
enabled in the following situations:
●When the engine switch 
is turned off
●If only the TRAC system is turned off, the 
TRAC will turn on when vehicle speed 
increases
If both the TRAC and VSC systems are 
turned off, automatic re-enabling will not 
occur when vehicle speed increases.
■Secondary Collision Brake operating 
conditions
The vehicle speed is approximately 6 mph 
(10 km/h) or more and the airbag sensor 
detects a collision. (The Secondary Colli-
sion Brake will not operate when the vehicle 
speed is below approximately 6 mph [10 
km/h].)
■Secondary Collision Brake automatic 
cancellation
The Secondary Collision Brake is automati-
cally canceled in the following situations.
●The vehicle speed drops below approxi-
mately 6 mph (10 km/h)
●A certain amount of time elapses during 
operation
●The accelerator pedal is depressed a 
large amount
■If “Secondary Collision Brake system 
Malfunction” is displayed on the multi-
information display
The system may be ma lfunctioning. Have 
the vehicle inspected at your Lexus dealer.
■Reduced effectiveness of the EPS sys-
tem
The effectiveness of the EPS system is 
reduced to prevent the system from over-
heating when there is frequent steering 
input over an extended period of time. The 
steering wheel may feel heavy as a result. 
Should this occur, re frain from excessive 
steering input or stop the vehicle and turn 
the engine 
tem should return to normal within 10 min-
utes. 

2535-3. Using the air conditioning system
5
Interior features
■Windshield wiper de-icer (if equipped)
This feature is used to prevent ice from 
building up on the wi ndshield and wiper 
blades.
The windshield de-icer will automatically 
turn off after approximately 15 minutes.
■Eco air conditioning mode
When Eco drive mode is selected using the 
driving mode select switch, eco air condi-
tioning mode turns on.
When a drive mode other than Eco drive 
mode is selected, eco air conditioning 
mode may turn off.
■Micro dust and pollen filter
Outside air mode switches to   
(recirculated air) mode. Pollen is removed 
from the air and the air flows to the upper 
part of the body.
Usually the system will automatically turn 
off after approximately 1 to 3 minutes.
In order to prevent the windshield from fog-
ging up when the outside air is cold, the 
dehumidification function may operate or 
the outside/recirculat ed air mode may not 
switch to   (recirculated air) mode.
Pollen is filtered even if the micro dust and 
pollen filter is turned off.
1 Press the automatic mode switch or 
select “AUTO” on the sub function 
menu. ( P.251) 2
Press the outside/recirculated air 
mode switch to switch to automatic 
air intake mode.
The air conditioning system automatically 
switches between outside air and recircu-
lated air modes.
3Adjust the temperature setting.
4 To stop the operation, press the off 
switch or select “Off” on the sub 
function menu. ( P.251)
If the fan speed setting or air flow 
modes are operated, the automatic 
mode indicator goes off. However, 
automatic mode for functions other 
than that operated is maintained.
■Using automatic mode
Fan speed is adjusted automatically accord-
ing to the temperature setting and the 
ambient conditions.
Therefore, the fan may stop for a while until 
warm or cool air is ready to flow immedi-
ately after the automatic mode switch is 
pressed or “AUTO” is selected.
Cool air may blow around the upper body 
even when the heater is on due to sunlight.
■Windshield fog detection function
When automatic mode is set, the humidity 
sensor detects fog on  the windshield and 
controls the air condit ioning system to pre-
vent fog.
■Automatic mode for air intake control
In automatic mode, the system detects 
exhaust gas and other pollutants and auto-
matically switches between outside air and 
recirculated air modes.
When the dehumidification function is off, 
and the fan is operating, turning automatic 
mode on will activate the dehumidification 
function.
WARNING
■To prevent burns (vehicles with wind-
shield wiper de-icer)
Do not touch the glass at lower part of 
the windshield or to the side of the front 
pillars when the wind shield wiper de-icer 
is on.

a sensor which monitors the temperature 
of the windshield, the surround humidity, 
etc. is installed.
Follow these points to avoid damaging 
the sensor:
●Do not disassemb le the sensor
●Do not spray the glass cleaner on the 
sensor or subject it to strong impacts
●Do not stick anything on the sensor

the door may lock and unlock repeatedly. In 
that case, follow the following correction 
procedures to wash the vehicle:
●Place the key in a position 6 ft. (2 m) or 
more separate from the vehicle while the 
vehicle is being washed. (Take care to 
ensure that the key is not stolen.)
●Set the electronic key to battery-saving 
mode to disable the smart access system 
with push-button start. ( P.115)
■Aluminum wheels

• Do not allow dirt and dust to accumulate 
on the windows for a long period.
Clean the windows with a soft, damp 
cloth as soon as possible.
• Do not use wax or glass cleaners that  contain abrasives when cleaning the win- dows.
• Do not use any metallic objects to  remove condensation build up.
●When the water-repellent performance 
has become insufficient, the coating can 
be repaired. Contact  your Lexus dealer.
