WARNING
●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 con- 
trol to hold the vehicle on an incline,  as doing so may lead to an acci-dent.
■When the TRC/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 TRC/VSC systems are turned off 
Be especially careful and drive at a  speed appropriate to the road condi-tions. As these are the systems to  
help ensure vehicle stability and driv- ing force, do not turn the TRC/VSC systems off unless necessary.
■Expert mode precautions
●Do not use on public roads.
●Use only when the road conditions and safely of the surrounding area  
can be ensured.
●Proper use of expert mode requires 
a professional level of driving skill.  When using expert mode, always check the road conditions and sur- 
rounding area and drive more care- fully than usual.
■Replacing tires 
Make sure that all tires are of the  specified size, brand, tread pattern  
and total load capacity. In addition,  make sure that the tires are inflated to the recommended tire inflation pres- 
sure level. The ABS, TRC and VSC systems will not function correctly if different tires  
are installed on the vehicle. Contact any authorized Toyota retailer or Toyota authorized repairer, or any  
reliable repairer for further information  when replacing tires or wheels.
■Handling of tires and the suspen-sion 
Using tires with any kind of problem  
or modifying the suspension will affect  the driving assist systems, and may cause a system to malfunction.
■Secondary Collision Brake (if equipped) 
Do not rely solely upon the Secondary  Collision Brake. This system is designed to help reduce the possibil- 
ity of further damage due to a second- ary collision, however, that effect changes according to various condi- 
tions. Overly relying on the system  may result in death or serious injury.
■Active Torque Split AWD system
●The Active Torque Split AWD sys-tem is designed to ensure driving  
stability on general roads and not  for off-road driving such as for rally-ing. Do not subject the system to  
extreme driving conditions.
●Drive carefully on slippery road sur-
faces.

the driving conditions: 
 Do not try to forcibly open a win- 
dow or move a wiper that is fro- 
zen. 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 accu- 
mulated on the air inlet vents in  
front of the windshield. 
 Check for and remove any  
excess ice or snow that may  
have accumulated on the exte- 
rior 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 shift the  
shift lever to 1 or R without set- 
ting the parking brake. The park- 
ing 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 danger- 
ous because it may cause the  
vehicle to move unexpectedly,  
possibly leading to an accident. 
Use the correct tire chain size when  
mounting the tire chains. 
Chain size is regulated for each tire  
size.
Side chain: 
3 mm (0.12 in.) in diameter 
10 mm (0.39 in.) in width 
30 mm (1.18 in.) in length
Cross chain: 
4 mm (0.16 in.) in diameter 
14 mm (0.55 in.) in width
25 mm (0.98 in.) in length 
Regulations regarding the use of  
tire chains vary depending on loca- 
tion and type of road. Always check  
local regulations before installing

6-2. Matte paint care guide (if equipped)
Maintenance and care
Take care in order to not damage  
the painted surfaces. 
When minor damage occurs to a  
vehicle with a normal clear coat, it  
can be repaired by polishing it or  
using touch up paint. In contrast, a  
matte clear coat cannot be repaired  
using these methods. 
If these methods are used the  
unevenness of the matte clear coat  
may be removed or filled in. In  
either case, the surface will  
become more flat, making it appear  
more glossy, possibly permanently  
losing its matte properties. 
In order to maintain the matte finish  
when repairing damage, it will be  
necessary to repaint the entire part. 
 Vehicle paint can be deteriorated  
by ultraviolet rays, rain, and  
other natural factors. In order to  
ensure the life of the paint, it is  
recommended that the vehicle  
be stored in a paved garage  
which blocks the paint from  
direct sunlight, rain, wind, and  
ground moisture. 
 If a vehicle cover is to be used,  
use one with an inner side which  
is fleece, non-woven, etc. as it is  
less likely to damage the paint.  
Even when using a vehicle  
cover, storing the vehicle in a  
paved garage is recommended.
■Using a vehicle cover
●Use an appropriately sized vehicle  
cover for your vehicle. For details,

6-4. Do-it-yourself maintenance 
molded into the sidewall of each tire. 
Replace the tires if the treadwear indi- 
cators are showing on a tire.
■When to replace your vehicle’s  tires 
Tires should be replaced if:
●The treadwear indicators are showing  on a tire.
●You have tire damage such as cuts, splits, cracks deep enough to expose  
the fabric, and bulges indicating inter- nal damage
●A tire goes flat repeatedly or cannot be properly repaired due to the size or location of a cut or other damage 
If you are not sure, consult with any  authorized Toyota retailer or Toyota authorized repairer, or any reliable  
repairer.
■Tire life 
Any tire over 6 years old must be  checked by a qualified technician even if  
it has seldom or never been used, or  damage is not obvious.
■Low profile tires 
Generally, low profile tires will wear  
more rapidly and tire grip performance  will be reduced on snowy and/or icy roads when compared to standard tires.  
Be sure to use snow tires on snowy  and/or icy roads and drive carefully at a speed appropriate for road and weather  
conditions.
■If the tread on snow tires wears  down below 4 mm (0.16 in.) 
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.
WARNING
■When inspecting or replacing tires 
Observe the following precautions to  prevent accidents.Failure to do so may cause damage  
to parts of the drive train as well as  dangerous handling characteristics, which may lead to an accident result- 
ing in death or serious injury.
●Do not mix tires of different makes, 
models or tread patterns. Also, do not mix tires of remarkably different treadwear.
●Do not use tire sizes other than those recommended by Toyota.
●Do not mix differently constructed 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 previously.
NOTICE
■Low profile 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 inflation pressure. If tires are under-inflated, they may be damaged more  
severely.
●Avoid potholes, uneven pavement, 
curbs and other road hazards. Fail- ure to do so may lead to severe tire and wheel damage.

pressure as part of your routine of daily  
vehicle checks.
■Tire inflation pressure
●It may take a few minutes to display 
the tire inflation pressure after the  engine switch is turned to ON. It may also take a few minutes to display the  
tire inflation pressure after inflation  pressure has been adjusted.
●Tire inflation pressure changes with temperature. The displayed values may also be different from the values  
measured using a tire pressure  gauge.
■Situations in which the tire pres-sure warning system may not oper- 
ate properly
●In the following cases, the tire pres-
sure warning system may not operate  properly.• If non-genuine Toyota wheels are  
used. • A tire has been replaced with a tire that is not an OE (Original Equipment)  
tire. • A tire has been replaced with a tire that is not of the specified size. 
• Tire chains, etc. are equipped. • An auxiliary-supported run-flat tire is equipped. 
• If a window tint that affects the radio  wave signals is installed.• If there is a lot of snow or ice on the  
vehicle, particularly around the wheels  or wheel housings.• If the tire inflation pressure is  
extremely higher than the specified  level.• If tires not equipped with tire pressure  
warning valves and transmitters are  used.• If the ID code on the tire pressure  
warning valves and transmitters is not  registered in the tire pressure warning computer.
●Performance may be affected in the following situations. 
• Near a TV tower, electric power plant,  gas station, radio station, large dis-play, airport or other facility that gen-
