4-5. Using the driving support systems
Driving
●When there are spinning objects near
your vehicle such as the fan of an air conditioning unit
●When water is splashed or sprayed toward the rear bumper, such as from a sprinkler
●Moving objects (flags, exhaust fumes, large rain droplets or snowflakes, rain
water on the road surface, etc.)
●When the distance between your vehi-
cle and a guardrail, wall, etc., that enters the detection area is short
●Gratings and gutters
●When a sensor or the area around a
sensor is extremely hot or cold
●If the suspension has been modified
or tires of a size other than specified are installed
●If the front of the vehicle is raised or lowered due to the carried load
1 Normal mode
Provides an optimal balance of
dynamic performance. Suitable for city
driving.
Press the switch to change the driving
mode to normal mode when not in nor-
mal mode.
2 Sport mode
Controls the driving force to distribute
more to the rear wheels, allowing the
vehicle to behave more crispy by steer-
ing wheel operation.
3 Track mode
Equally distributes the driving force
among the 4 wheels, maximizing the
Active Torque Split AWD system. Suit-
able for driving on racing circuits.
■Automatic deactivation of sport mode and track mode
If the engine switch is turned off after
AWD mode select switch
The following modes can be
selected to suit the driving and
road conditions by controlling
the drive force to the front and
rear wheels.

4-5. Using the driving support systems
■TRC (Traction Control)
Helps to maintain drive power and
prevent the drive wheels from spin-
ning when starting the vehicle or
accelerating on slippery roads
■Hill-start assist control
Helps to reduce the backward
movement of the vehicle when
starting on an uphill
■EPS (Electric Power Steering)
Employs an electric motor to
reduce the amount of effort needed
to turn the steering wheel.
■Active Torque Split AWD sys-
tem
Automatically switches from front-
wheel drive to all-wheel drive
(AWD) according to the driving con-
ditions, helping to ensure reliable
handling and stability. Examples of
conditions where the system will
switch to AWD are when cornering,
going uphill, starting off or acceler-
ating, and when the road surface is
slippery due to snow, rain, etc.
■Emergency brake signal
When the brakes are applied sud-
denly, the emergency flashers auto-
matically flash to alert the vehicle
behind.
■The secondary Collision Brake
(if equipped)
When the SRS airbag sensor
detects a collision and the system
operates, the brakes and brake
lights are automatically controlled
to reduce the vehicle speed and
help reduce the possibility of further
damage due to a secondary colli-
sion.
■When the TRC/VSC systems are operating
The slip indicator light will flash while the
TRC/VSC systems are operating.
■Disabling the TRC system
If the vehicle gets stuck in mud, dirt or
snow, the TRC system may reduce
power from the engine to the wheels.
Pressing to turn the system off may
make it easier for you to rock the vehicle
in order to free it.
To turn the TRC system off, quickly
press and release .
The “TRC OFF” indicator light will come
on.
Press again to turn the system
back on.
■Turning off both TRC and VSC sys-
tems
To turn the TRC and VSC systems off,

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.

Maintenance and care
faces up to avoid scratching the wheel
surface.
1 Remove any dirt or foreign mat-
ter from the wheel contact sur-
face.
If foreign matter is on the wheel contact
surface, the wheel nuts may loosen while the vehicle is in motion, causing the tire to come off.
2 Install the tire and loosely
tighten each wheel nut by hand
by approximately the same
amount.
Turn the wheel nuts until the washers come into contact with the disc wheel.

WARNING
■Replacing a tire
●Observe the following precautions.
Failure to do so may result in serious
injury:
Do not touch the disc wheels or the
area around the brakes immediately
after the vehicle has been driven.
After the vehicle has been driven the
disc wheels and the area around the
brakes will be extremely hot. Touch-
ing these areas with hands, feet or
other body parts while changing a tire,
etc., may result in burns.
●Failure to follow these precautions
could cause the wheel nuts to loosen and the tire to fall off, result-ing in death or serious injury.
• Have the wheel nuts tightened with a torque wrench to 103 N•m (10.5
kgf•m, 76 ft•lbf) as soon as possible after changing wheels.
• When installing a tire, only use wheel nuts that have been specifi-cally designed for that wheel.
• If there are any cracks or deforma- tions in the bolt screws, nut threads
or bolt holes of the wheel, have the vehicle inspected by any authorized Toyota retailer or Toyota authorized
repairer, or any reliable repairer.

4 Firmly tighten each wheel nut
two or three times in the order
shown in the illustration.
Tightening torque: 103 N•m (10.5 kgf•m, 76 ft•lbf)
5 Stow the tire jack and all tools.
■After completing the tire change
The tire pressure warning system must be reset. ( P.280)
Tire inflation pressure is specified
on the label on the driver’s side
door frame as shown.
Left-hand drive vehicles
Right-hand drive vehicles
WARNING
■After using the tools and jack
Before driving, make sure all the tools and jack are securely in place in their
storage location to reduce the possi- bility of personal injury during a colli-sion or sudden braking.
Tire inflation pressure
Make sure to maintain proper
tire inflation pressure. Tire
inflation pressure should be
checked at least once per
month. However, Toyota rec-
ommends that tire inflation
pressure be checked once
every two weeks. ( P. 3 5 5 )
