2014 TOYOTA RAV4 EV cooling

30 1-1. EV system
■Charging
Be sure you maintain the traction battery charge level for your driving needs.
If the traction battery fully discharges, the vehicle cannot be driven a\
t all.
Even when driving, keep early charging in mind. ( P. 53) If the amount of
charge remaining in the traction battery becomes low, search for a charging
station using the navigation system*.
* For details, refer to the “Navigation System Owner's Manual”.
■ Driving Range
Based on the amount of charge remaining in the traction battery, the air-con-
ditioning system mode and so forth, the calculated driving range is displayed
on the meter.
Depending on driving speed, road surface conditions, method of air-condi-
tioning use, and so forth, the actual driving distance may increase or
decrease. Keep early charging in mind.
■ Noise and vibrations specific to an electric vehicle
Because an electric vehicle does not have the engine noise or vibrations
that a conventional vehicle has, the driver may not notice that the ready indi-
cator is illuminated and the vehicle is in a drivable condition. For safety rea-
sons, always shift the shift position to P and apply the parking brake when
parking the vehicle.
After starting the EV system, the following noises and vibrations may occur.
These noises and/or vibrations are not signs of a malfunction. For example:
● Motor sounds coming from the motor compartment.
● Electrical relay sounds may be heard from the traction battery when the
EV system starts or stops.
● Sounds may be heard from the transmission and its surrounding area
when the EV system starts or stops.
● Sounds may be heard due to regenerative braking when you depress the
brake pedal or release the accelerator pedal.
● Motor sounds may be heard when accelerating suddenly.
● Operational and motor sounds may be heard when the brake pedal is
depressed.
● The electric cooling fans in the front of the vehicle may be heard.
● Air conditioning operation sounds may be heard.

54 1-3. Charging
*: By using a smart phone, pre-climate operations and so forth can
be performed from a distant location. ( P. 58)
■ Important things to check be fore charging and pre-climate
operations (Remote Climate Control)
Before charging and pre-climate operations, always check that:
● The parking brake is securely set ( P. 216)
● The shift position is in P ( P. 206)
● All windows and doors are closed
● The motor compartment hood is securely closed
If the hood is open the electric cooling fans will not operate, raising
the temperature of the charger and traction battery. This may
increase charging time or cause charging to be aborted.
●All lights are turned off (For example, the headlights, emer-
gency flashers, interior lights, etc.)
If any lights are turned on, then these features will consume electric-
ity, and charging time will increase.
SystemDetails
Pre-climate
(Remote Climate
Control)*
The time when pre-climate operations are to be
completed by can be set for each day of the
week. Cabin temperature is adjusted before depar-
ture by performing climate control operations,
thereby reducing traction battery consumption
after departure. If these operations are per-
formed while the vehicle is plugged in, the
traction battery's power consumption is
reduced, increasing driving range. ( P. 66)
If the amount of charge remaining in the trac-
tion battery is 50% or less at the time pre-cli-
mate operations begin, pre-climate operations
will not be performed in order to preserve driv-
ing range.

■Pre-climate (Remote Climate Control)
By setting the sched ule, the air conditioning system can be
turned on before getting in the vehicle. ( P. 5 3 )
Even if the schedule has not been set, for users who own a
smart phone, the air conditioning system can be turned on and
off when away from the vehicle. ( P. 5 8 )

The operating section of the air conditioning panel uses capaci-
tive touch sensors. ( P. 290)

The air conditioning system
begins to operate in AUTO ECO
LO mode. Air outlets and fan
speed are automatically adjusted
according to the temperature

In AUTO ECO mode, depending
on the outside temperature and
the set temperature, the seat
heater operates, and the seat
heater’s temperature is automati-
cally adjusted. (P. 310)
When in AUTO mode, air condi-

Interior features
■Outside/recirculated air mode
●When driving on dusty roads such as tunnels or in heavy traffic, set the
outside/recirculated air mode button to the recirculated air mode. This is
effective in preventing outside air from entering the vehicle interior. Dur-
ing cooling operation, setting the recirculated air mode will also cool the
vehicle interior effectively.
● Outside/recirculated air mode may automatically switch depending on
the temperature setting, the inside temperature, the outside temperature
and humidity.
Also, outside air mode may be automatically switched to when the out-
side temperature is low.
■ When the outside temperature exceeds 75 F (24C) and the air condi-
tioning system is on
● In order to reduce the air conditioning power consumption, the air condi-
tioning system may switch to recirculated air mode automatically. This
may also reduce traction battery power consumption.
● Recirculated air mode is selected as a default mode when the “POWER”
switch is turned to ON mode.
● It is possible to switch to outside air mode at any time by touching .
■ Air conditioning odors
●During use, various odors from inside and outside the vehicle may enter
into and accumulate in the air conditioning system. This may then cause
odor to be emitted from the vents.
● To reduce potential odors from occurring:
• It is recommended that the air conditioning system be set to outside air
mode prior to turning the vehicle off.
• The start timing of the blower may be delayed for a short period of time after the air conditioning system is started in AUTO mode.
■ Air conditioning filter

288 3-1. Using the air conditioning system and defogger
■Operation of the air conditio ning system in AUTO ECO mode
In the AUTO ECO mode, the air conditioning system is controlled as follows
to prioritize driving range:
● Compressor operation controlled to restrict heating/cooling capacity
● Fan speed restricted when automatic mode is selected
■ The seat heater when using ECO LO or ECO HI mode
Depending on the outside temperature and the set temperature, the seat
heater is automatically operated and its temperature adjusted. The seat
heater can be adjusted to a desired temperature using the seat heater con-
trol. ( P. 310)
When it is desirable to set the cabin tem-
perature to a more comfortable one,
move the operating mode closer to
“NORMAL” by pressing ECO. When it is
desirable to increase driving range, move
the selected mode closer to “OFF” by
pressing ECO.

CAUTION
The motor compartment contains many mechanisms and fluids that may move
suddenly, become hot, or become electrically energized. To avoid death or
serious injury, observe the following precautions:
■When working on the motor compartment
●Make sure that the indicator on the “POWER” switch and the “READY”
indicator are both off.
● Keep hands, clothing and tools away from the moving fans.
● Be careful not to touch the motor, power control unit, radiator, heater, etc.
right after driving as they may be hot. Coolant and other fluids may also be
hot.
● Do not leave anything that may burn easily, such as paper and rags, in the
motor compartment.
● Do not smoke, cause sparks or expose an open flame to the 12-volt bat-
tery. 12-volt battery fumes are flammable.
● Be extremely cautious when working on the 12-volt battery. It contains poi-
sonous and corrosive sulfuric acid.
● Take care because brake fluid can harm your hands or eyes and damage
painted surfaces.
If fluid gets on your hands or in your eyes, flush the affected area with
clean water immediately.
If you still experience discomfort, see a doctor.
● Never touch, disassemble, remove or replace the high voltage parts,
cables and their connectors. It can cause severe burns or electric shock
that may result in death or serious injury.
■ When working near the electric c ooling fans or radiator grille
Be sure the “POWER” switch is off.
With the “POWER” switch in ON mode, the electric cooling fans may auto-
matically start to run if the air conditioning is on and/or the coolant tempera-
ture is high. ( P. 360)
■ Safety glasses
Wear safety glasses to prevent flying or falling material, fluid spray, etc. from
getting in the eyes.
