Capacity), and permissible draw-
bar load before towing. ( P. 4 2 0 )
Toyota recommends the use of the
Toyota hitch/bracket 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 following shall be
observed:
 Do not use towing devices that
cannot be easily removed or
repositioned.
 Towing devices must be
removed or repositioned when
not in use.
■Total trailer weight and per-
missible drawbar load
Total trailer weight
Weight of the trailer itself plus the trailer
load should be within the maximum
towing capacity. Exceeding this weight
is dangerous. ( P.420)
When towing a trailer, use a friction
coupler or friction stabilizer (sway con-
trol device).
Permissible drawbar load
Allocate the trailer load so that the
drawbar load is greater than 25 kg
(55.1 lb.) or 4% of the towing capacity.
Do not let the drawbar load exceed the
indicated weight. ( P.420)
■Information tag (manufac-
turer’s label)
Gross vehicle mass
The combined weight of the driver, pas-
sengers, luggage, towing hitch, total
curb mass and drawbar load should not
exceed the gross vehicle mass by more
than 100 kg (220.5 lb.). Exceeding this
weight is dangerous.
Maximum permissible rear axle
capacity
The weight borne by the rear axle
should not exceed the maximum per-
missible rear axle capacity by 15% or
more. Exceeding this weight is danger-
ous. The values for towing capacity
were derived from testing conducted at
sea level. Take note that engine output
and towing capacity will be reduced at
high altitudes.

HV Owner's Manual_Europe_M52N30_en
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.
WARNING
F o l l o w a l l t h e i n s t r u c t i o n s d e s c r i b e d i n
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)

4-2. Driving procedures
Driving
Turns EV drive mode on/off
When EV drive mode is turned on, the
EV drive mode indicator will come on.
Pressing the switch when in EV drive
mode will return the vehicle to normal
driving (using the gasoline engine and
electric motor [traction motor]).
■Situations in which EV drive mode cannot be turned on
It may not be possible to turn EV drive
mode on in the following situations. If it cannot be turned on, a buzzer will sound and a message will be shown on the
multi-information display.
NOTICE
■To prevent 12-volt battery dis- charge
Do not stop the hybrid system when the shift lever is in a position other than P. If the hybrid system is stopped
in another shift lever position, the power switch will not be turned off and remained to ON. If the vehicle is left in
ON, battery discharge may occur.
EV drive mode
In EV drive mode, electric
power is supplied by the
hybrid battery (traction bat-
tery), and only the electric
motor (traction motor) is used
to drive the vehicle.
This mode allows you to drive
in residential areas early in the
morning and late at night, or in
indoor parking lots, etc., with-
out concern for noises and gas
emissions.

4-2. Driving procedures
●The temperature of the hybrid system
is high. The vehicle has been left in the sun, driven on a hill, driven at high speeds,
etc.
●The temperature of the hybrid system
is low. The vehicle has been left in tempera-tures lower than about 0°C (32°F) for
a long period of time, etc.
●The gasoline engine is warming up.
●The hybrid battery (traction battery) is low.
The remaining battery level indicated in the energy monitor display is low. ( P.120)
●Vehicle speed is high.
●The accelerator pedal is depressed firmly or the vehicle is on a hill, etc.
●The windshield defogger is in use.
■Switching to EV drive mode when the gasoline engine is cold
If the hybrid system is started while the
gasoline engine is cold, the gasoline engine will start automatically after a short period of time in order to warm up.
In this case, you will become unable to switch to EV drive mode.
After the hybrid system has started and
the “READY” indicator has illuminated, press the EV drive mode switch before the gasoline engine starts to switch to
EV drive mode.
■Automatic cancelation of EV drive mode
When driving in EV drive mode, the gas-
oline engine may start automatically and the vehicle may be driven by the gaso-line engine and electric motor (traction
motor) in the following situations. When EV drive mode is canceled, a buzzer will sound, the EV drive mode indicator will
flash, and a message will be displayed on the multi-information display.
●The hybrid battery (traction battery) becomes low.The remaining battery level indicated
in the energy monitor display is low.
( P.120)
●Vehicle speed is high.
●The accelerator pedal is depressed firmly or the vehicle is on a hill, etc.
■Possible driving distance when driving in EV drive mode
EV drive mode’s possible driving dis- tance ranges from a few hundred meters to approximately 1 km (0.6 mile).
However, depending on vehicle condi- tions, there are situations when EV drive mode cannot be used.
(The distance that is possible depends on the hybrid battery [traction battery] level and driving conditions.)
■Fuel economy
The hybrid system is designed to achieve the best possible fuel economy during normal driving (using the gaso-
line engine and electric motor [traction motor]). Driving in EV drive mode more than necessary may lower fuel econ-
omy.
■If “EV Mode Unavailable” is shown on the multi-information display
The EV drive mode is not available. The
reason the EV drive mode is not avail- able (the vehicle is idling, battery charge is low, vehicle speed is higher than the
EV drive mode operating speed range or accelerator pedal is depressed too much) may be displayed. Use the EV
drive mode when it becomes available.
■If “EV Mode Deactivated” is shown on the multi-information display
The EV drive mode has been automati-
cally canceled. The reason the EV drive mode is not available (the battery charge is low, vehicle speed is higher
than the EV drive mode operating speed range or accelerator pedal is depressed too much) may be displayed. Drive the
vehicle for a while before attempting to turn on the EV drive mode again.

■When driving with dynamic radar
cruise control with full-speed range activated
Even when switching the driving mode
to power mode with the intent of enabling engine braking, engine braking will not occur because dynamic radar
cruise control with full-speed range will not be canceled. ( P.275)
WARNING
■Caution while driving
When driving in EV drive mode, pay
special attention to the area around the vehicle. Because there is no engine noise, pedestrians, people rid-
ing bicycles or other people and vehi- cles in the area may not be aware of the vehicle starting off or approaching
them.
Take extra care while driving even if the acoustic vehicle alerting system is
active.

: While the power switch is in
ON and the brake pedal
depressed*, shift the shift lever
while pushing the shift release but-
ton on the shift knob.
: Shift the shift lever while push-
ing the shift release button on the
shift knob.
: Shift the shift lever normally.
When shifting the shift lever between P
and D, make sure that the vehicle is
completely stopped.
*: For the vehicle be able to be shifted
from P, the brake pedal must be
depressed before the shift release
button is pushed. If the shift release
button is pushed first, the shift lock
will not be released.
■Shift lock system
The shift lock system is a system to pre- vent accidental operation of the shift lever in starting.
The shift lever can be shifted from P only when the power switch is in ON and the brake pedal is being depressed.
■If the shift lever cannot be shifted
from P
First, check whether the brake pedal is being depressed.
If the shift lever cannot be shifted with your foot on the brake pedal, there may be a problem with the shift lock system.
Have the vehicle inspected by any authorized Toyota retailer or Toyota authorized repairer, or any reliable
repairer immediately. The following steps may be used as an emergency measure to ensure that the
shift lever can be shifted. Releasing the shift lock:
1 Set the parking brake.
2 Turn the power switch off.
WARNING
■When driving on slippery road surfaces
Do not accelerate or shift gears sud- denly. Sudden changes in engine braking
may cause the vehicle to spin or skid, resulting in an accident.
NOTICE
■Hybrid battery (traction battery) charge
If the shift lever is in N, the hybrid bat-
tery (traction battery) will not be charged even when the engine is run-ning. Therefore, if the vehicle is left
with the shift lever in N for a long period of time, the hybrid battery (traction battery) will discharge, and
this may result in the vehicle not being able to start.

screwdriver or equivalent tool. To prevent damaging the cover, wrap the tip of the flathead screw-
driver with a tape.
5 Press and hold the shift lock override
button and then push the button on the shift knob.
The shift lever can be shifted while the
both buttons are pressed.
■About engine braking
When shift position B is selected, releasing the accelerator pedal will apply engine braking.
●When the vehicle is driven at high speeds, compared to ordinary gaso-
line-fueled vehicles, the engine brak- ing deceleration is felt less than that of other vehicles.
●The vehicle can be accelerated even when shift position B is selected.
If the vehicle is driven continuously in the B position, fuel efficiency will become low. Usually, select the D posi-
tion.

WARNING
■To prevent an accident when releasing the shift lock
Before pressing the shift lock override button, make sure to set the parking brake and depress the brake pedal.
If the accelerator pedal is accidentally depressed instead of the brake pedal when the shift lock override button is
pressed and the shift lever is shifted out of P, the vehicle may suddenly start, possibly leading to an accident
resulting in death or serious injury.

static object detection and display
(warning buzzer sounds). Even at low speeds, there is a possibility that the object will come within 30 cm (1.0 ft.)
before the display is shown and the warning buzzer sounds.• It might be difficult to hear the buzzer
due to the volume of the audio system or air flow noise of the air conditioning system.
• It may be difficult to hear the sound of this system due to the buzzers of other systems.
■Objects which the system may not
be properly detected
The shape of the object may prevent the sensor from detecting it. Pay particular
attention to the following objects:
●Wires, fences, ropes, etc.
●Cotton, snow and other materials that absorb sound waves
●Sharply-angled objects
●Low objects
●Tall objects with upper sections pro-
jecting outwards in the direction of your vehicle
■Situations in which the system may not operate properly
Certain vehicle conditions and the sur- rounding environment may affect the ability of a sensor to correctly detect
objects. Particular instances where this may occur are listed below.
●There is dirt, snow, water drops or ice on a sensor. (Cleaning the sensors will resolve this problem.)
●A sensor is frozen. (Thawing the area will resolve this problem.)
In especially cold weather, if a sensor is frozen the sensor display may be displayed abnormally, or objects, such
as a wall, may not be detected.
●When a sensor or the area around a
sensor is extremely hot or cold.
●On an extremely bumpy road, on an
incline, on gravel, or on grass.
●When vehicle horns, vehicle detec-
tors, motorcycle engines, air brakes of large vehicles, the clearance sonar of other vehicles or other devices which
produce ultrasonic waves are near the vehicle
●A sensor is coated with a sheet of spray or heavy rain.
●If objects draw too close to the sensor.
●Pedestrians that are hard to reflect
ultrasonic waves (ex. skirts with gath- ers or frills).
●When objects that are not perpendicu-lar to the ground, not perpendicular to the vehicle traveling direction,
uneven, or waving are in the detection range.
●Strong wind is blowing
●When driving in inclement weather
such as fog, snow or a sandstorm
●When an object that cannot be
detected is between the vehicle and a detected object
●If an object such as a vehicle, motor-cycle, bicycle or pedestrian cuts in front of the vehicle or runs out from
the side of the vehicle
●If the orientation of a sensor has been
changed due to a collision or other impact
●When equipment that may obstruct a sensor is installed, such as a towing eyelet, bumper protector (an addi-
tional trim strip, etc.), bicycle carrier, or snow plow
●If the front of the vehicle is raised or lowered due to the carried load
