Driving assist systems
When the Enhanced VSC is operatingIf the vehicle is in danger of slip-
ping or the front wheels spin, the
indicator flashes to indicate that
the Enhanced VSC have been
engaged.
A buzzer (intermittent) sounds to
indicate that Enhanced VSC is
operating.
The slip indicator light flashes as
well when ABS is operating.
To help enhance driving safety and performance, the following sys-
tems operate automatically in res ponse to various driving situations.
Be aware, however, that these systems are supplementary and
should not be relied upon too h eavily when operating the vehicle.
■ABS (Anti-lock Brake System)
Helps to prevent wheel lock when the brakes are applied suddenly, or if
the brakes are applied while driving on a slippery road surface.
■Brake Assist
Generates an increased level of braking force after the brake pedal is
depressed, when the system detects a panic stop situation.
■Enhanced VSC (Vehicle Stab ility Control) (If equipped)
Helps the driver to control skidding when swerving suddenly or turning
on slippery road surfaces.
■EPS (Electric Power Steering)
Employs an electric motor to reduce the amount of effort needed to turn
the steering wheel.

■Sounds and vibrations caused by the ABS, brake assist and Enhanced
VSC
● A sound may be heard from the hybrid system compartment when the
hybrid system is started or just after the vehicle begins to move. This
sound does not indicate that a malfunction has occurred in any of these
systems.
● Any of the following conditions may occur when the above systems are
operating. None of these indicates that a malfunction has occurred.
• Vibrations may be felt through the vehicle body and steering.
• A motor sound may be heard after the vehicle comes to a stop.
• The brake pedal may pulsate slightly after the ABS is activated.
• The brake pedal may move down slightly after the ABS is activated.
■ Reduced effectiveness of EPS
The effectiveness of EPS is reduced to prevent the system from overheating
when there is frequent steering input over an extended period of time. The
steering wheel may feel heavy as a result. Should this occur, refrain from
excessive steering input or stop the vehicle and turn the hybrid system OFF.
The system should return to normal within 10 minutes.

CAUTION
■Storage precautions
●Do not stack anything in the luggage compartment higher than the
seatbacks.
Such items may be thrown about and possibly injure people in the
vehicle during sudden braking or in an accident.
●Do not place anything on the luggage cover.
Such items may be thrown about and possibly injure people in the
vehicle during sudden braking or in an accident.
●Do not drive with objects on top of the instrument panel.
They may interfere with the driver’s field of view or move during sharp
acceleration or turning, thus impairing the driver’s control of the vehi-
cle. In an accident they may injure the vehicle occupants.
●Secure all items in the occupant compartment, as they may shift and
injure someone during an accident or sudden braking.
●Never allow anyone to ride in the luggage compartment. It is not
designed for passengers. They should ride in their seats with their seat
belts properly fastened. Otherwise,
they are much more likely to suffer
death or serious injury, in the event of sudden braking or a collision.
■Weight of the load
●Improper loading may cause deterioration of steering or braking con-
trol resulting in an accident which may cause death or serious injury.
●Do not exceed the maximum axle weight rating or the total vehicle
weight rating.
●Even if the total load of occupant’s weight and the cargo load is less
than the total load capacity, do no t apply the load unevenly. Improper
loading may cause deterioration of st eering or braking control which
may cause death or serious injury.

Vehicle load limits
■Total load capacity and seating capacity
These details are also described on the tire and loading information
label. (P. 384)
CAUTION
■Overloading the vehicle
Do not overload the vehicle.
It may not only cause damage to the ti res, but also degrade steering and
braking ability, resulting in an accident.
Vehicle load limits include total load capacity, seating capacity,
towing capacity and cargo capacity.
■ Total load capacity: 810 lb. (365 kg)
Total load capacity means the combined weight of occupants,
cargo and luggage.
■ Seating capacity: 5 occupants (Front 2, Rear 3)
Seating capacity means the ma ximum number of occupants
whose estimated average weight is 150 lb. (68 kg) per person.
Even if the number of occupants are within the seating capacity,
do not exceed the total load capacity.
■ Towing capacity
Toyota does not recommend towing a trailer with your vehicle.
■ Cargo capacity
Cargo capacity may increase or decrease depending on the
weight and the number of occupants.
