●Acceleration Suppression at Low Speed
The Acceleration Suppression at Low Speed function will not ope rate when 
the turn signal lig hts are flashing.
While the Acceleration Suppression at Low Speed function is ope rating, if 
any of the following are performed, the low speed sudden acceleration sup-
pression function oper ation will be cancelled:
• The accelerator pedal is released.
• The steering wheel is ope rated heavily or suddenly
■Detection of detectable objects
Objects are detected based on their 
size, shape, and movement.
Depending on the ambient bright-
ness, movement, pos ture and direc-
tion of a detectable object, it may 
not be detected and the system may 
not operate properly.
The system detects shapes, such as 
the following, as de tectable objects.
■Situations in which the system 
may operate even though the 
possibility of a collision is not 
high
●In certain situations, such as the 
following, the sys tem may deter-
mine that the possibility of a colli-
sion is high and operate:
• When passing a detectable object
• When changing lanes while over-
taking a detectable object • When suddenly approaching a 
detectable object
• When approaching a detectable 
object or other ob ject on the road-
side, such as guardrails, utility 
poles, trees, walls, etc.
• When there is a d etectable object 
or other object by  the roadside at 
the entrance  of a curve
• When there are patterns or a  painting ahead of the vehicle that 
may be mistaken for a detectable 
object
• When passing a detectable object 
that is changing lanes or turning 
left/right

WARNING
■Active Cornering Assist does 
not operate effectively when
●Do not overly rely on Active 
Cornering Assist. Active Corner-
ing Assist may not operate 
effectively when accelerating 
down slopes or driving on slip-
pery road surfaces.
●When Active Cornering Assist 
frequently operates, Active Cor-
nering Assist may temporarily 
stop operating to ensure proper 
operation of the brakes, TRAC 
and VSC.
■Hill-start assist control does 
not operate effectively when
●Do not overly rely on hill-start 
assist control. Hill-start assist 
control may not operate effec-
tively on steep inclines and 
roads covered with ice.
●Unlike the parking brake, 
hill-start assist control is not 
intended to hold the vehicle sta-
tionary for an extended period 
of time. Do not attempt to use 
hill-start assist control to hold 
the vehicle on an incline, as 
doing so may lead to an acci-
dent.
■When the TRAC/VSC is acti-
vated
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 sys-
tems to help ensure vehicle stabil-
ity and driving force, do not turn 
the TRAC/VSC systems off 
unless necessary.
■Secondary Collision Brake
Do not rely solely upon the Sec-
ondary Collision Brake. This sys-
tem is designed to help reduce 
the possibility of  further damage 
due to a secondary collision, how-
ever, that effect changes accord-
ing to various conditions. Overly 
relying on the system may result 
in death or serious injury.
■Replacing tires
Make sure that all tires are of the 
specified size, brand, tread pat-
tern and total load capacity. In 
addition, make sure that the tires 
are inflated to the recommended 
tire inflation p ressure level.
The ABS, TRAC and VSC sys-
tems will not functi on correctly if 
different tires are installed on the 
vehicle.
Contact your Toyota dealer for fur-
ther information when replacing 
tires or wheels.
■Handling of tires and the sus-
pension
Using tires with any kind of prob-
lem or modifying the suspension 
will affect the driving assist sys-
tems, and may cause a system to 
malfunction. 

2304-6. Driving tips
4-6.Driving tips
Use fluids that are appropriate 
to the prevailing outside tem-
peratures.
• Engine oil
• Engine coolant
• Washer fluid
Have a service technician 
inspect the condition of the 
battery.
 Have the vehicle fitted with 
four snow tires or purchase a 
set of tire chains for the front 
tires.
Ensure that all tires are the same 
size and brand, and that chains 
match the size of the tires.
Winter driving tips
Carry out the necessary 
preparations and inspec-
tions before driving the 
vehicle in winter. Always 
drive the vehicle in a man-
ner appropriate to the pre-
vailing weather conditions.
Pre-winter preparations
WARNING
■Driving with snow tires
Observe the following precautions 
to reduce the risk of accidents.
Failure to do so m ay result in a 
loss of vehicle control and cause 
death or serious injury.
●Use tires of the size specified.
●Maintain the recommended 
level of air pressure.
●Do not drive in excess of 75 
mph (120 km/h), regardless of 
the type of snow tires being 
used.
●Use snow tires on all, not just 
some wheels.
■Driving with tire chains
Observe the following precautions 
to reduce the risk of accidents.
Failure to do so may result in the 
vehicle being unable to be driven 
safely, and may cause death or 
serious injury.
●Do not drive in excess of the 
speed limit specifi ed for the tire 
chains being used, or 30 mph 
(50 km/h), whichever is lower.
●Avoid driving on bumpy road 
surfaces or over potholes.
●Avoid sudden acceleration, 
abrupt steering, sudden brak-
ing and shifting operations that 
cause sudden engine braking.
●Slow down sufficiently before 
entering a curve to ensure that 
vehicle control is maintained.
●Do not use LTA (Lane Tracing 
Assist) system.
●Do not use LDA  (Lane Depar-
ture Alert) system.
NOTICE
■Repairing or replacing snow 
tires
Request repairs or replacement of 
snow tires from Toyota dealers or 
legitimate tire retailers.
This is because the removal and 
attachment of snow tires affects 
the operation of the tire pressure 
warning valves and transmitters. 

2314-6. Driving tips

Driving
Perform the following according 
to the driving conditions:
Do not try to forcibly open a 
window or move a wiper that 
is frozen. Pour 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 wind-
shield.
 Check for and remove any 
excess ice or snow that may 
have accumulated 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 suit-
able to road conditions.
 Turn automatic mode of the 
parking brake off. Otherwise,  the parking brake may freeze 
and not be able to be 
released automatically.
Also, avoid using the following as 
the parking brake may operate 
automatically, even if automatic 
mode is off.
• Brake hold system
Park the vehicle and shift the 
shift lever to P without setting 
the parking brake. The park-
ing brake may freeze up, pre-
venting 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 dan-
gerous because it may cause 
the vehicle to move unexpect-
edly, possibly leading to an 
accident.
 When the parking brake is in 
automatic mode, release the 
parking brake after shifting 
the shift lever to P. ( P.142)
 If the vehicle is parked without 
setting the parking brake, 
confirm that the shift lever 
cannot be moved out of P.
 If the vehicle is left parked 
with the brakes damp in cold 
temperatures, there is a pos-
sibility of the brakes freezing.
Use the correct tire chain size 
when mounting the tire chains.

tires also have radial construction. 
Do not install stud ded tires without 
first checking local regulations for 
possible restrictions. Snow tires 
should be installed on all wheels. 
(  P.230)
■If the tread on snow tires wears 
down below 0.16 in. (4 mm)
The effectiveness of the tires as 
snow tires is lost.
■Checking the tire valves
When replacing the tires, check the 
tire valves for deformation, cracks, 
and other damage.
Rotate the tires in the order 
shown.
WARNING
■When inspecting or replacing 
tires
Observe the following precautions 
to prevent accidents.
Failure to do so may cause dam-
age to parts of t he drive train as 
well as dangerous handling char-
acteristics, which may lead to an 
accident resulting in death or seri-
ous injury.
●Do not mix tires of different 
makes, models or tread pat-
terns.
Also, do not mix tires of remark-
ably different treadwear.
●Do not use tire sizes other than 
those recommended by Toyota.
●Do not mix differently con-
structed tires (radial, bias-belted 
or bias-ply tires).
●Do not mix summer, all season 
and snow tires.
●Do not use tires that have been 
used on another vehicle.
Do not use tires if you do not 
know how they were used previ-
ously.
NOTICE
■Low profile tires (18-inch 
tires)
Low profile tires may cause 
greater damage than usual to the 
tire wheel when sustaining impact 
from the road surface. Therefore, 
pay attention to the following:
●Be sure to use proper tire infla-
tion pressure. If tires are 
under-inflated, they may be 
damaged more severely.
●Avoid potholes, uneven pave-
ment, curbs and other road haz-
ards. Failure to do so may lead 
to severe tire a nd wheel dam-
age.
■If tire inflation pressure of 
each tire becomes low while 
driving
Do not continue driving, or your 
tires and/or wheels may be 
ruined.
■Driving on rough roads
Take particular care when driving 
on roads with loose surfaces or 
potholes.
These conditions may cause 
losses in tire inflation pressure, 
reducing the cushioning ability of 
the tires. In addition, driving on 
rough roads may cause damage 
to the tires themselves, as well as 
the vehicle’s wheels and body.
