3045-1. Before driving
WARNING
●In order to prevent accidents due to
the vehicle rolling away, always
keep depressing the brake pedal while stopped with the “READY”
indicator is illuminated, and apply
the parking brake as necessary.
●If the vehicle is stopped on an
incline, in order to prevent acci -
dents caused by t he vehicle rolling forward or backward, always
depress the brake pedal and
securely apply the parking brake as needed.
●Avoid revving or racing the engine.Running the engine at high speed
while the vehicle is stopped may
cause the exhaust system to over- heat, which could result in a fire if
combustible material is nearby.
■When the vehicle is parked
●Do not leave glasses, cigarette
lighters, spray can s, or soft drink cans in the vehicle when it is in the
sun.
Doing so may result in the follow - ing:
• Gas may leak from a cigarette
lighter or spray c an, and may lead to a fire.
• The temperature inside the vehicle
may cause the plastic lenses and plastic material of glasses to
deform or crack.
• Soft drink cans may fracture, caus - ing the contents to spray over the
interior of the vehicle, and may also
cause a short circuit in the vehicle’s electrical components.
●Do not leave cigarette lighters in the vehicle. If a cigarette lighter is in a
place such as the glove box or on
the floor, it may be lit accidentally when luggage is loaded or the seat
is adjusted, causing a fire.
●Do not attach adhesive discs to the windshield or windows. Do not
place containers such as air fresh -
eners on the instrument panel or dashboard. Adhesive discs or con -
tainers may act as lenses, causing
a fire in the vehicle.
●Do not leave a door or window
open if the curved glass is coated with a metallized fi lm such as a sil-
ver-colored one. Reflected sunlight
may cause the gl ass to act as a lens, causing a fire.
●Always apply the parking brake, shift the shift lev er to P, stop the
hybrid system and lock the vehicle.
Do not leave the vehicle unat - tended while the “READY” indicator
is illuminated.
If the vehicle is parked with the shift lever in P but the parking brake is
not set, the vehicl e may start to
move, possibly leading to an acci - dent.
●Do not touch the exhaust pipes while the “READY” indicator is illu -
minated or immediately after turn -
ing the hybrid system off. Doing so may cause burns.
■When taking a nap in the vehicle
Always turn the hybrid system off.
Otherwise, if you accidentally move
the shift lever or depress the acceler - ator pedal, this could cause an acci -
dent or fire due to hybrid system
overheating. Additionally, if the vehi - cle is parked in a poorly ventilated
area, exhaust gases may collect and
enter the vehi cle, leading to death or a serious health hazard.

5-1. Before driving
Driving
Check the allowable towing capac -
ity, GVM (Gross Vehicle Mass),
MPAC (Maximum Permissible Axle
Capacity), and permissible drawbar
load before towing. ( →P.618)
Toyota recommends the use of the
Toyota hitch/bracke t for your vehi-
cle. Other products of a suitable
nature and comparable quality may
also be used.
For vehicles where the towing
device blocks any of the lights or
license plate, the fo llowing shall be
observed:
 Do not use towing device that
cannot be easily removed or
repositioned.
 Towing devices must be
removed or repositioned when
not in use.
Please consult a ny authorized
Toyota retailer or Toyota authorized
repairer, or any reliable repairer
when installing tra iler lights, as
incorrect installa tion may cause
damage to the vehicle’s lights.
Please take care to comply with
your state’s laws when installing
trailer lights.

WARNING
●Do not use dynamic radar cruise
control with full- speed range (if
equipped) or cruise control (if equipped) when trailer towing.
■Vehicle speed in towing
Observe the legal maximum speeds
for trailer towing.
■Before descending hills or long declines
Reduce speed and downshift. How -
ever, never downshift suddenly while descending steep or long downhill
grades.
■Operation of the brake pedal

5-1. Before driving
Driving
■Sudden acceleration/steering
input/cornering
Executing sharp turns when towing
may result in the trailer colliding
with your vehicle. D ecelerate well in
advance when approaching turns
and take them slowly and carefully
to avoid sudden braking.
■Important points regarding
turning
The wheels of the tr ailer will travel
closer to the inside of the curve
than the wheels of the vehicle. To
make allowance for this, take the
turns wider than you would nor -
mally do.
■Important points regarding
stability
Vehicle movement resulting from
uneven road surfaces and strong
crosswinds will affect handling. The
vehicle may also be rocked by
passing buses or large trucks. Fre -
quently check behind when moving
alongside such vehicles. As soon
as such vehicle movement occurs,
immediately start to decelerate
smoothly by slowly applying the
brakes. Always steer the vehicle
straight ahead while braking.
■Passing other vehicles
Consider the total combined length
of your vehicle and trailer and
ensure that the vehicle-to-vehicle
distance is sufficient before execut -
ing lane changes.
■Transmission information
To maintain engine braking effi -
ciency, when using engine braking,
do not use the transmission in D.
( →P.321)
■If the hybrid system overheats
Towing a loaded trailer up a long,
steep incline in temperatures
exceeding 30°C (85°F) may result
in the hybrid system overheating. If
the high coolant temperature warn -
ing light indicates that the hybrid
system is overheating, turn the air
conditioning off immediately, leave
the road and stop the vehicle in a
safe place. ( →P.611)
■When parking the vehicle
Always place wheel chocks under
the wheels of both the vehicle and
trailer. Firmly set the parking brake
and shift the shift lever to P.
■Break-in schedule
Toyota recommends that vehicles fitted
with new power train components
should not be used for towing trailers for the first 800 km (500 miles).
■Maintenance
●Maintenance must be performed more frequently when using the vehicle for
towing due to the greater weight bur -
den placed on the vehicle compared to normal driving.
●Retighten all bolts securing the hitch - ing ball and bracket after towing for
approximately 1000 km (600 miles).
■If trailer sway occurs
One or more factor s (crosswinds, pass- ing vehicles, rough roads, etc.) can
adversely affect handling of your vehicle
and trailer, causing instability.
