2013 TOYOTA CAMRY HYBRID cooling

34 1-1. Hybrid system
■Sounds and vibrations specific to a hybrid vehicle
There may be no engine sounds or vibration even though the vehicle is able
to move. Always shift the shift lever to P when parked.
The following sounds or vibrations may occur when the hybrid system is
operating and are not a malfunction:
●Motor sounds may be heard from the engine compartment.
● Sounds may be heard from the hybrid battery (traction battery) behind
the rear seats when the hybrid system starts or stops.
● Sounds from the hybrid system may be heard when the trunk lid is open.
● Sounds may be heard from the transmission when the hybrid system
starts or stops.
● Engine sounds may be heard when accelerating sharply.
● Sounds may be heard due to regenerative braking when the brake pedal
is depressed.
● Operational sounds and motor sounds may be heard when the brake
pedal is operated.
● Vibration may be felt when the gasoline engine starts or stops.
● Cooling fan sounds may be heard from the air intake vent beside the rear
left seat.
■ Vehicle Proximity Notification System
In the following cases, the Vehicle Proximity Notification System sound may
be difficult for pedestrians, people riding bicycles or other people and vehi-
cles in the surrounding area to hear:
●When there is a lot of noise in the vicinity
● When it is raining or during strong winds
● When in the area surrounding the rear of the vehicle, rather than in front
of the vehicle
■ Maintenance, repair, recycling, and disposal
Contact your Toyota dealer regarding maintenance, repair, recycling and dis-
posal. Do not dispose of the vehicle yourself.

36 1-1. Hybrid system
Hybrid battery air vent There is an air intake vent beside
the rear left seat for the purpose
of cooling the hybrid battery
(traction battery). If the vent
becomes blocked, the hybrid
battery may overheat, leading to
a reduction in hybrid battery out-
put.
Emergency shut off system When a certain level of impact is detected by the impact sensor, the
emergency shut off syst em blocks off the high voltage current and
stops the fuel pump to minimize t he risk of electrocution and fuel
leakage. If the emergency shut off system activates, your vehicle will
not restart. To restart the hybrid system, contact your Toyota dealer.
Hybrid warning message
A message is automatically displayed when a malfunction occurs in
the hybrid system or an impr oper operation is attempted.
If a warning message is shown
on the multi-information display,
read the message and follow the
instructions. ( P. 433)

2-1. Driving procedures

When driving
■
Operation of the air conditio ning system in Eco drive mode
Eco drive mode controls the heating/cooling operations and fan speed of the
air conditioning system to enhance fuel efficiency. ( P. 240) To improve air
conditioning performance, adjust the fan speed or turn off Eco drive mode.
■ When in heavy traffic
If the shift lever is in N, the hybrid battery (traction battery) will not be
charged. To help prevent the battery from discharging, avoid putting the shift
lever in N for an extended period of time.
■ If the shift lever cannot be shifted from P
P. 466
CAUTION
■When driving on slippery road surfaces
Do not accelerate or shift gears suddenly.
Sudden changes in engine braking may cause the vehicle to spin or skid,
resulting in an accident.
■ Selecting Eco drive mode
When the vehicle is driven in Eco drive mode, vehicle driving
force and operation of the air co nditioning system (heating/cool-
ing) is controlled to improve fuel efficiency.
Eco drive mode
When eco drive mode is turned
on, the “ECO MODE” indicator
will come on.
Pressing the “ECO MODE”
switch again turns eco drive
mode off.

Interior features
■Operation of the air conditio ning system in Eco drive mode
In Eco drive mode, the air conditioning sy stem is controlled as follows to pri-
oritize fuel efficiency:
● Engine speed and compressor operation controlled to restrict heating/
cooling capacity
● Fan speed restricted when automatic mode is selected
To improve air conditioning performance, perform the following operations:
● Adjust the fan speed
● Turn off Eco drive mode
■ Customization
The air conditioning control of Eco drive mode can be changed to the same
setting as that used in normal drive mode.
(Customizable features P. 510)
■ Using automatic mode
Fan speed is adjusted automatically according to the temperature setting
and the ambient conditions.
Therefore, the fan may stop for a while until warm or cool air is ready to flow
immediately after is pressed.
■ Fogging up of the windows
●The windows will easily fog up when the humidity in the vehicle is high.
Turning on will dehumidify the air from the outlets and defog the
windshield effectively.
● If you turn off, the windows may fog up more easily.
● The windows may fog up if the recirculated air mode is used.
■ Windshield fog detection function
When automatic mode is set, the humidity sensor ( P. 248) detects fog on
the windshield and controls the air conditioning system to prevent fog.

246 3-1. Using the air conditioning system and defogger
■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 or the inside temperature.
■ 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 fuel 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 pressing
.
■ When the outside temperat ure falls to nearly 32F (0 C)
The dehumidification function may not operate even when is
pressed.

Maintenance and care
CAUTION
The engine 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 engine compartment
●Make sure that the “READY” indicator is off.
● Keep hands, clothing and tools away from the moving fans and engine
drive belt.
● Be careful not to touch the engine, power control unit, radiator, exhaust
manifold, etc. right after driving as they may be hot. Oil and other fluids
may also be hot.
● Do not leave anything that may burn easily, such as paper and rags, in the
engine compartment.
● Do not smoke, cause sparks or expose an open flame to fuel. Fuel fumes
are flammable.
■ 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. 370)
■ Safety glasses
Wear safety glasses to prevent flying or falling material, fluid spray, etc. from
getting in your eyes.
NOTICE
■If you remove the air cleaner filter
Driving with the air cleaner filter removed may cause excessive engine wear
due to dirt in the air.
