*: If equipped
Safe Exit Assist*
The safe exit assist is a sys-
tem that uses rear side 
radar sensors installed on 
the inner side of the rear 
bumper to help occupants 
judge if an approaching 
vehicle or bicycle may col-
lide with a door when open-
ing it or cancel opening of 
the door, to reduce the pos-
sibility of a collision.
WARNING
■Cautions regarding the use of 
the system
●The driver is solely responsible 
for safe driving. Always drive 
safely, taking care to observe 
your surroundings.
●The safe exit assist is a supple-
mentary system that, when the 
vehicle is stopped, informs 
occupants of the existence of 
approaching vehicles and bicy-
cles. As this system alone can-
not be used to judge safety, 
over-reliance on this system 
may lead to an accident result-
ing in death or serious injury.
In certain situations, this system 
may not function to its fullest 
extent. Therefore it is necessary 
for the occupants to visually 
check for safety directly and using 
the mirrors. 

2284-5. Using the driving support systems
●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 sys-
tems are turned off, automatic 
re-enabling will not occur when 
vehicle speed increases.
■Operating conditions of Active 
Cornering Assist
The system operates when the fol-
lowing occurs.
●TRAC/VSC can operate
●The driver is at tempting to accel-
erate while turning
●The system detects that the vehi-
cle is drifting to the outer side
●The brake pedal is released
■Reduced effectiveness of the 
EPS system
The effectiveness of the EPS sys-
tem is reduced to prevent the sys-
tem from overheating when there is 
frequent steering input over an 
extended period of time. The steer-
ing 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 syst em should return 
to normal within 10 minutes.
■Secondary Collision Brake 
operating conditions
The system operates when the SRS 
airbag sensor detects a collision 
while the vehicle is in motion.
However, the system does not oper-
ate when the components are dam-
aged.
■Secondary Collision Brake 
automatic cancellation
The system is automatically can-
celed in any of th e following situa-
tions.
●The vehicle speed drops below 
approximately 0 mph (0 km/h)
●A certain amount of time elapses 
during operation
●The accelerator pedal is 
depressed a large amount
WARNING
■The ABS does not operate 
effectively when
●The limits of tire gripping perfor-
mance have been exceeded 
(such as excessively 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 dis-
tance. Always maintain a safe dis-
tance from the veh icle in front of 
you, especially in  the following sit-
uations:
●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/VSC may not operate 
effectively when
Directional control and power may 
not be achievable while driving on 
slippery road surfaces, even if the 
TRAC/VSC system is operating. 
Drive the vehicle  carefully in con-
ditions where stability and power 
may be lost.

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.

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.
