Driving
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.

Dirt
Due to the slight unevenness, matte
clear coat surfaces are more likely to
trap dirt and other foreign matter com-
pared to normal clear coat surfaces.
If dirt or foreign matter is left on the
vehicle, it may settle into the textured
surface of the matte clear coat, making
it more difficult to remove. Additionally,
as the surface of the matte clear coat
will become more flat when dirty, the
vehicle body will start to look glossy,
ruining the textured finish.
Therefore, make sure to clean the vehi-
cle regularly and not allow dirt to remain
on the vehicle for extended periods of
time.
If dirt or foreign matter is allowed to set-
tle and cannot be cleaned off with nor-
mal washing, it will be necessary to
remove the dirt with the upper layer of
the textured finish and then to repaint
the entire part.
Ask your any authorized Toyota retailer
or Toyota authorized repairer, or any
reliable repairer for details.
■Materials that may become difficult to remove
The following are likely to settle into the
vehicle body and should be cleaned off immediately.
●Rain water, sea water, and other liq-uids that may cause water stains
●Sand, pollen, volcanic ash, and other particulate matter
●Dead insects, bird droppings, etc.
●Sap, leaves, flowers, etc.
●Mud, snow, anti-freezing agents, and other road debris
●Gasoline, engine oil, asphalt, and other oily materials
■Do not wax or apply a coating to
the vehicle
Do not wax the vehicle or apply a coat-
ing to the vehicle body, as they will form a film over the painted surfaces, filling the matte clear coat surface, making it
more flat. As a result, it will become more glossy, possibly permanently los-ing its matte properties.

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,

■If the vehicle body is dirty (P.253)
Question: What should I do if any of the following have attache d to the vehi-
cle?
ItemAnswer
Leaves, flowers, branches,
etc.
Remove immediately.
They may scratch the matte clear coat and if they are
allowed to remain on the vehicle, dirt may settle into
the matte clear coat, making it more flat. As a result, it
will become more glossy, possibly permanently losing
its matte properties.
Dead insects, bird drop-
pings, etc.
Remove immediately.
They may scratch the matte clear coat and if they are
allowed to remain on the vehicle, dirt may settle into
the matte clear coat, making it more flat. As a result, it
will become more glossy, possibly permanently losing
its matte properties.
Sand, pollen, and other
particulate matter
Wash off with water immediately.
If the contaminants cannot be removed with water
alone, use a neutral detergent solution. If the contami-
nants are allowed to remain on the vehicle, they may
settle into the matte clear coat, making it more flat. As
a result, it will become more glossy, possibly perma-
nently losing its matte properties.
Oil stains
Asphalt (tar)
Wa t e r s t ai n sUse dilute citric acid (citric acid powder dissolved in
distilled water) to remove the water stains.
Water repellent glass coat-
ing
Remove immediately.
Even if removed, depending on the contaminant, the
matte clear coat may be damaged, possibly perma-
nently losing its matte properties.

6-3. Maintenance
request that a record of maintenance
be kept.
■Does your vehicle need repairs?
Be on the alert for changes in perfor- mance and sounds, and visual tip-offs
that indicate service is needed. Some important clues are:
●Engine misses (misfire), stumbling or pinging
●Appreciable loss of power
●Strange engine noises
●A fluid leak under the vehicle (How-ever, water dripping from the air con-
ditioning system after use is normal.)
●Change in exhaust sound (This may
indicate a dangerous carbon monox- ide leak. Drive with the windows open and have the exhaust system checked
immediately.)
●Flat-looking tires, excessive tire
squeal when cornering, uneven tire wear
●Vehicle pulls to one side when driven straight on a level road
●Strange noises related to suspension movement
●Loss of brake effectiveness, spongy feeling brake pedal or clutch pedal (vehicles with a manual transmission),
pedal almost touches the floor, vehicle pulls to one side when braking
●Engine coolant temperature continu-ally higher than normal ( P.81, 84)
If you notice any of these clues, take
your vehicle to any authorized Toyota
retailer or Toyota authorized repairer, or
any reliable repairer as soon as possi-
ble. Your vehicle may need adjustment
or repair.

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.
