1964-5. Using the driving support systems
■When the message is displayed on the 
multi-information display showing that 
TRAC has been disabled even if the  switch has not been pressed
TRAC cannot be operated. Contact your 
Lexus dealer.
■Operating conditions of hill-start assist 
control
When the following four conditions are met, 
the hill-start assist control will operate:
●The shift lever is in a  position other than P 
or N (when starting off forward/back-
ward on an upward incline).
●The vehicle is stopped.
●The accelerator pedal is not depressed.
●The parking brake is not engaged.
■Automatic system cancelation of 
hill-start assist control
The hill-start assist control will turn off in any 
of the following situations:
●The shift lever is moved to P or N.
●The accelerator pedal is depressed.
●The parking brake is engaged.
●Approximately 2 seconds elapse after 
the brake pedal is released.
■VGRS is disabled when
VGRS may stop operating in the following 
situations.
In this event, the steering wheel may move 
from its straight forward position, but it will 
return when the system restarts.
●When the steering wheel is operated for 
an extended period  of time while the 
vehicle is stopped or is moving very 
slowly 
(on vehicles with LDH, DRS is disabled 
together with VGRS)
●When the steering wheel has been held 
fully to the left or right
The center position of the steering wheel 
may change when VGRS is disabled. How-
ever, the position will return to normal after 
VGRS is reactivated.
■When the battery is disconnected (vehi-
cles 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, VSC, 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.
• The brake pedal may pulsate slightly after  the ABS is activated.
• The brake pedal may move down slightly  after the ABS is activated.
■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.
■Reactivation of the TRAC/VSC systems
Even after the TRAC /VSC systems have 
been turned off, turning the engine off and 
then on again will automatically reactivate 
the TRAC/VSC systems.
■Reactivation of the TRAC system linked 
to vehicle speed
When only the TRAC system is turned off, 
the TRAC system will turn on when vehicle 
speed increases. Ho wever, when both 
TRAC/VSC systems are turned off, the sys-
tems will not turn on even when vehicle 
speed increases.
■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, refrain from excessive 
steering input or stop the vehicle and turn 
the engine off. The EPS system should 
return to normal within 10 minutes.
WARNING
■The ABS does not operate effectively 
when
●The limits of tire gripping performance 
have been exceeded (such as exces-
sively worn tires on a snow covered 
road).
●The vehicle hydroplanes while driving 
at high speed on wet or slick roads.
■Stopping distance when the ABS is 
operating may exceed that of normal 
conditions
The ABS is not designed to shorten the 
vehicle’s stopping di stance. Always main-
tain a safe distance from the vehicle in 
front of you, especially in the following 
situations:
●When driving on dirt, gravel or 
snow-covered roads
●When driving with tire chains
●When driving over bumps in the road
●When driving over roads with potholes 
or uneven surfaces
■TRAC may not operate effectively 
when
Directional control and power may not 
be achievable while driving on slippery 
road surfaces, even if the TRAC system is 
operating. Drive the vehicle carefully in 
conditions where stability and power 
may be lost.
■Hill-start assist control does not oper-
ate effectively when
●Do not overly rely on hill-start assist 
control. Hill-start assist control may 
not operate effectively on steep 
inclines and roads covered with ice.
●Unlike the parking brake, hill-start 
assist control is not intended to hold 
the vehicle stationary for an extended 
period of time. Do not attempt to use 
hill-start assist control to hold the vehi-
cle on an incline, as doing so may lead 
to an accident.
■When the VSC is activated
The slip indicator light flashes. Always 
drive carefully. Reckless driving may 
cause an accident. Exercise particular 
care when the indicator light flashes.
■When the TRAC/VSC systems are 
turned off
Be especially careful and drive at a speed 
appropriate to the road conditions. As 
these are the systems to help ensure 
vehicle stability and driving force, do not 
turn the TRAC/VSC systems off unless 
necessary.
■Replacing tires
Make sure that all ti res are of the speci-
fied size, brand, tread pattern and total 
load capacity. In addition, make sure that 
the tires are inflated to the recom-
mended tire inflation pressure level.
The ABS, TRAC and VSC systems will 
not function correctly if different tires are 
installed on the vehicle.
Contact your Lexus dealer for further 
information when replacing tires or 
wheels.
■Handling of tires and the suspension
Using tires with any kind of problem or 
modifying the suspensi on will affect the 
driving assist systems, and may cause a 
system to malfunction.

Driving
warm water over the frozen area to 
melt the ice. Wipe away the water 
immediately to prevent it from 
freezing.
 To ensure proper operation of the 
climate control system fan, remove 
any snow that has accumulated on 
the air inlet vents in front of the 
windshield.
 Check for and remove any excess 
ice or snow that may have accumu-
lated on the exterior lights, vehicle’s 
roof, chassis, around the tires or on 
the brakes.
 Remove any snow or mud from the 
bottom of your shoes before getting 
in the vehicle.
Accelerate the vehicle slowly, keep a 
safe distance between you and the 
vehicle ahead, and drive at a reduced 
speed suitable to road conditions.
 Park the vehicle and move the shift 
lever to P without setting the park-
ing brake. The parking brake may 
freeze up, preventing it from being 
released. If the vehicle is parked 
without setting the parking brake, 
make sure to block the wheels.
Failure to do so may be dangerous 
because it may cause the vehicle to 
move unexpectedly, possibly lead-
ing to an accident.
 If the vehicle is parked without set- ting the parking brake, confirm that 
the shift lever cannot be moved out 
of P
*.
*: The shift lever will be locked if it is 
attempted to be shifted from P to any 
other position with out depressing the 
brake pedal. If the shift lever can be 
shifted from P, there may be a problem 
with the shift lock system. Have the vehi-
cle inspected by your Lexus dealer 
immediately.
Vehicles with front and rear tires of 
the same size except for vehicles 
with LDH and 19-inch tires
Use the correct tire chain size when 
mounting the tire chains. 
Chain size is regulated for each tire 
size.
Side chain (0.12 in. [3 mm] in diam-
eter)
Cross chain (0.16 in. [4 mm] in 
diameter)
Vehicles with front and rear tires of 
differing sizes and vehicles with 
LDH and 19-inch tires
Tire chains cannot be mounted.
Snow tires should be used instead.

Maintenance and care
■Brake fluid can absorb moisture from 
the air
Excess moisture in the brake fluid can cause 
a dangerous loss of braking efficiency. Use 
only newly opened brake fluid.
Check the battery as follows.
■Battery exterior
Make sure that the battery terminals 
are not corroded and that there are no 
loose connections, cracks, or loose 
clamps. Terminals
Hold-down clamp
■Before recharging
When recharging, the battery produces 
hydrogen gas which is flammable and 
explosive. Therefore, observe the following 
before recharging:
●If recharging with the battery installed on 
the vehicle, be sure to disconnect the 
ground cable.
●Make sure the power switch on the char-
ger is off when connecting and discon-
necting the charger cables to the battery.
■After recharging/reconnecting the bat-
tery
The engine may not start. Follow the proce-
dure below to initialize the system.
1
Shift the shift lever to P.
2
Open and close either door.
3
Restart the engine.
●Unlocking the doors using the smart 
access system with pu sh-button start may 
not be possible immediately after recon-
necting the battery. If this happens, use 
the wireless remote control or the 
mechanical key to lock/unlock the doors.
●Start the engine with the engine switch in 
ACCESSORY mode. The engine may 
not start with the engine switch turned off. 
However, the engine will operate nor-
mally from the second attempt.
●The engine switch mode is recorded by 
the vehicle. If the battery is disconnected 
and reconnected, the vehicle will return 
the engine switch mode to the status it 
was in before the battery was discon-
nected. Make sure to turn off the engine 
before disconnecting the battery. Take 
extra care when connecting the battery if 
the engine switch mode prior to the bat-
tery being disconnected is unknown.
If the system will not start even after multi-
ple attempts, contact your Lexus dealer.
WARNING
■When filling the reservoir
Take care as brake fluid can harm your 
hands and eyes and damage painted sur-
faces.If fluid gets on your hands or in your 
eyes, flush the affected area with clean 
water immediately.
If you still experience discomfort, see a 
doctor.
NOTICE
■If the fluid level is low or high
It is normal for the brake fluid level to go 
down slightly as the brake pads wear out 
or when the fluid level in the accumulator 
is high.
