2012 TOYOTA CAMRY HV battery

34 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. 423)

■
If a warning light comes on, a warn ing message is displayed, or the 12-
volt battery has been disconnected
The hybrid system may not start. In that case, try to start the system again. If
the “READY” indicator does not come on, contact your Toyota dealer.
■ Running out of fuel
When the vehicle has run out of fuel and the hybrid system cannot be
started, refuel the vehicle with at least enough gasoline to make the low fuel
level warning light ( P. 416) go off. If there is only a small amount of fuel,
the hybrid system may not be able to start. (The minimum amount of fuel to
add to make the low fuel level warning light go out is about 3.0 gal. [11.3 L,
2.5 Imp. gal] when the vehicle is on a level surface. This value may vary
when the vehicle is on a slope.)
■ Electromagnetic waves
●High voltage parts and cables on the hybrid vehicles incorporate electro-
magnetic shielding, and therefore emit approximately the same amount
of electromagnetic waves as conventional gasoline powered vehicles or
home electronic appliances.
● Your vehicle may cause sound interference in some third party-produced
radio parts.
■ Hybrid battery (traction battery)
The hybrid battery (traction battery) has a limited service life. The lifespan of
the hybrid battery (traction battery) can change in accordance with driving
style and driving conditions.

CAUTION
■
Road accident cautions
Observe the following precautions to reduce the risk of death or serious
injury:
●Pull your vehicle off the road, shift the shift lever to P, apply the parking
brake, and turn the hybrid system off.
● Do not touch the high voltage parts, cables or connectors.
● If electric wires are exposed inside or outside your vehicle, an electric
shock may occur. Never touch exposed electric wires.
● If a fluid leak occurs, do not touch the fluid as it may be strong alkaline
electrolyte from the hybrid battery (traction battery). If it comes into contact
with your skin or eyes, wash it off immediately with a large amount of water
or, if possible, boric acid solution. Seek immediate medical attention.
● If a fire occurs in the hybrid vehicle, leave the vehicle as soon as possible.
Never use a fire extinguisher that is not meant for electric fires. Using even
a small amount of water may be dangerous.
● If your vehicle needs to be towed, do so with the front wheels raised. If the
wheels connected to the electric motor (traction motor) are on the ground
when towing, the motor may continue to generate electricity. This may
cause a fire. (
P. 409)
● Carefully inspect the ground under the vehicle. If you find that liquid has
leaked onto the ground, the fuel system may have been damaged. Leave
the vehicle as soon as possible.
■ Nickel-metal hydride battery
Your vehicle contains a sealed nickel-metal hydride battery. If disposed of
improperly, it is hazardous to the environment and there is a risk of severe
burns and electrical shock that may result in death or serious injury.
■ Emergency shut off system
●Carefully check to see if there are exposed high voltage parts or cables.
Never touch the parts or cables. (P. 33)
● Carefully inspect the ground under the vehicle. If you find that liquid has
leaked onto the ground, the fuel system may have been damaged. Leave
the vehicle as soon as possible.

NOTICE
■Hybrid battery air vent
●Do not place foreign objects over or in front of the air vent. The hybrid bat-
tery (traction battery) may overheat and be damaged.
● Clean the air vent regularly to prevent the hybrid battery (traction battery)
from overheating.
● Do not wet the air vent as this may cause a short circuit and damage the
hybrid battery (traction battery).
● 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.

Keys
Using the mechanical keyTo take out the mechanical key,
push the release button and take
the key out.
The mechanical key can only be
inserted in one direction, as the
key only has grooves on one
side. If the key cannot be inserted
in a lock cylinder, turn it over and
re-attempt to insert it.
After using the mechanical key,
store it in the electronic key. Carry
the mechanical key together with
the electronic key. If the electronic
key battery is depleted or the
entry function does not operate
properly, you will need the
mechanical key. (P. 458)
The following keys are provid ed with the vehicle.
Electronic keys
• Operating the smart key
system ( P. 53)
• Operating the wireless remote control function

Battery-saving function
The battery-saving function will be activated in order to prevent the elec-
tronic key battery and the 12-volt battery from being discharged while the
vehicle is not in operation for a long time.
●In the following situations, the smart key system may take some time to
unlock the doors.
• The electronic key has been left in an area of approximately 6 ft. (2 m)
of the outside of the vehicle for 10 minutes or longer.
• The smart key system has not been used for 5 days or longer.
● If the smart key system has not been used for 14 days or longer, the
doors cannot be unlocked at any doors except the driver’s door. In this
case, take hold of the driver’s door handle, or use the wireless remote
control or the mechanical key, to unlock the doors.
■ Electronic Key Batter y-Saving Function
When battery-saving mode is set, battery depletion is minimized by stopping
the electronic key from emitting radio waves.
Press twice while pressing and
holding . Confirm that the electronic
key indicator flashes 4 times.
While the battery-saving mode is set, the
smart key system cannot be used. To
cancel the function, press any of the elec-
tronic key buttons.
