1-4. Hybrid system
There is an air intake vent under
the left side of the rear seat for the
purpose of cooling the hybrid bat-
tery (traction battery). If the vent
becomes blocked, the hybrid bat-
tery (traction battery) input and out-
put may be reduced.
When a certain level of impact is
detected by the impact sensor, the
emergency shut off system blocks
the high voltage current and stops
the fuel pump to minimize the risk
of electrocution and fuel leakage. If
the emergency shut off system acti-
WARNING
When reselling or handing over your vehicle, the possibility of an accident
is extremely high because the person receiving the vehicle may not be aware of these dangers.
●If your vehicle is disposed of with-out the hybrid battery having been
removed, there is a danger of seri- ous electric shock if high voltage parts, cables and their connectors
are touched. In the event that your vehicle must be disposed of, the hybrid battery must be disposed of
by any authorized Toyota retailer or Toyota authorized repairer, or any reliable repairer. If the hybrid bat-
tery is not disposed of properly, it may cause electric shock that can result in death or serious injury.
NOTICE
■Hybrid battery (traction battery) air intake vent
Do not carry large amounts of water such as water cooler bottles in the vehicle. If water spills onto the hybrid
battery (traction battery), the battery may be damaged. Have the vehicle inspected by any authorized Toyota
retailer or Toyota authorized repairer, or any reliable repairer.

WARNING
●Do not leave a door or window open if the curved glass is coated
with a metallized film such as a sil- ver-colored one. Reflected sunlight may cause the glass to act as a
lens, causing a fire.
●Always apply the parking brake,
shift the shift lever to P, stop the hybrid system and lock the vehicle.Do not leave the vehicle unat-
tended while the hybrid system is operating.If the vehicle is parked with the shift
lever in P but the parking brake is not set, the vehicle 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 vehicle, leading to death or
a serious health hazard.
■When braking
●When the brakes are wet, drive more cautiously.Braking distance increases when
the brakes are wet, and this may cause one side of the vehicle to brake differently than the other
side. Also, the parking brake may not securely hold the vehicle.
●If the electronically controlled brake system does not operate, do not fol-low other vehicles closely and avoid
hills or sharp turns that require braking.In this case, braking is still possible,
but the brake pedal should be depressed more firmly than usual. Also, the braking distance will
increase. Have your brakes fixed immediately.
●The brake system consists of 2 or more individual hydraulic systems; if one of the systems fails, the
other(s) will still operate. In this case, the brake pedal should be depressed more firmly than usual
and the braking distance will increase. Have your brakes fixed immediately.
■If the vehicle becomes stuck
Do not spin the wheels excessively
when a driven wheel is up in the air, or the vehicle is stuck in sand, mud, etc. This may damage the driveline
components or propel the vehicle for- ward or backward, causing an acci-dent.
NOTICE
■When driving the vehicle
●Do not depress the accelerator and brake pedals at the same time
during driving, as this may restrain the hybrid system output.
●Do not use the accelerator pedal or depress the accelerator and brake pedals at the same time to hold the
vehicle on a hill.
■When parking the vehicle
Always set the parking brake and shift the shift lever to P. Failure to do so may cause the vehicle to move or the
vehicle may accelerate suddenly if the accelerator pedal is accidentally depressed.

4-1. Before driving
Driving
Avoid sudden braking that may
cause skidding. Otherwise, the
vehicle may spin out of control. This
is especially true when driving on
wet or slippery road surfaces.
■Sudden acceleration/steering
input/cornering
Executing sharp turns when towing
may result in the trailer colliding
with your vehicle. Decelerate well in
advance when approaching turns
and take them slowly and carefully
to avoid sudden braking.
■Important points regarding
turning
The wheels of the trailer 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 and charging system perfor-
mance when using engine braking,
do not use the transmission in D.
( P.181)
■If the engine overheats
Towing a loaded trailer up a long,
steep incline in temperatures
exceeding 30°C (85°F) may result
in the engine overheating. If the
engine coolant temperature gauge
indicates that the engine is over-
heating, turn the air conditioning off
immediately, leave the road and
stop the vehicle in a safe place.
( P.414)
■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.

this section. Failure to do so could cause an accident resulting in death or serious injury.
■Trailer towing precautions
When towing, make sure that none of
the weight limits are exceeded. ( P.168)

WARNING
■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
Do not hold the brake pedal depressed often or for long periods of
time. Doing so may result in the brake overheating or reduce braking effects.
■To avoid accident or injury
●Vehicles with a compact spare tire: Do not tow a trailer when the com-
pact spare tire is installed on your vehicle.
●Vehicles with the emergency tire puncture repair kit: Do not tow a trailer when the tire installed is
repaired with the emergency tire puncture repair kit.
●Vehicles with a Dynamic radar cruise control: Do not use dynamic radar cruise control when you are
towing.
NOTICE
■Do not directly splice trailer
lights
Directly splicing trailer lights may damage your vehicle’s electrical sys-
tem and cause a malfunction.

until the “READY” indicator is steady
on, as steady means the vehicle is able to move.
●When the hybrid battery (traction bat-tery) is extremely cold (below approxi-mately -30°C [-22°F]) under the
influence of the outside temperature, it may not be possible to start the hybrid system. In this case, try to start the
hybrid system again after the tem- perature of the hybrid battery increases due to the outside tempera-
ture increase, etc.
