Hybrid battery air vent
There is an air intake vent on the
side of the lower part of the rear
left seat for the purpose of cool-
ing the hybrid battery (traction
battery). If the vent becomes
blocked, the hybrid battery (trac-
tion battery) may overheat, lead-
ing to a reduction in hybrid
battery output.
Emergency shut off system
When a certain level of impact is detected by the impact sensor, the
emergency shut off system blocks off the high voltage current and
stops the fuel pump to minimize the risk of electrocution and fuel
leakage. If the emergency shut off system activates, your vehicle will
not restart. To restart the hybrid system, contact any authorized Toy-
ota dealer or repairer, or another duly qualified and equipped profes-
sional.
If a warning light comes on, or the 12-volt battery is 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 any authorized Toyota
dealer or repairer, or another duly qualified and equipped professional.
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. 570) 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 7.0 L [1.8 gal.,
1.5 lmp. gal.] when the vehicle is on a level surface. This value may vary
when the vehicle is on a slope.)

CAUTION
To prevent burns or damage to your vehicle
NOTICE
To prevent damage to your vehicle
Do not turn the heater on and off repeatedly in 5 minute intervals as this
can shorten the life of the heater components. If the engine must be turned
on and off repeatedly within short intervals (such as when the vehicle is
being used for delivery purposes), turn the heater off.
Do not modify or open the heater without consulting any authorized Toyota
dealer or repairer, or another duly qualified and equipped professional, as
this may cause a heater malfunction or a fire.
Be careful not to splash or spill liquid directly on the heater or on the
heater fuel pump, as this may cause the heater to malfunction.
Keep the intake and exhaust pipes of the heater free from water, snow,
ice, mud, etc. If the pipes become clogged, this can cause the heater to
malfunction.
If you notice anything unusual, such as a fluid leak, smoke and poor oper-
ation, turn off the heater and have your vehicle checked by any authorized
Toyota dealer or repairer, or another duly qualified and equipped profes-
sional.
Do not touch the heater or its exhaust
pipe as they are hot. You may burn
yourself.
Keep flammable items such as fuel
away from the heater and its exhaust
pipe, as this may cause a fire.

Fuel filter (diesel engine only)
You may drain the fuel filter yourself. However, as the operation is dif-
ficult, we recommend having it drained by any authorized Toyota
dealer or repairer, or another duly qualified and equipped profes-
sional. Even if you decide to drain it yourself, contact any authorized
Toyota dealer or repairer, or another duly qualified and equipped pro-
fessional.
The water in the fuel filter needs to be drained if the fuel filter warning
light comes on. (P. 568)
Vehicles without a smart entry & start system:
Turn the engine switch to the “LOCK” position.
Vehicles with a smart entry & start system:
Turn the “ENGINE START STOP” switch off.
Place a small tray under the drain plug to catch the water and
any fuel that comes out.
Turn the drain plug counterclock-
wise about 2 to 2 1/2 turns.
Operate the priming pump until
fuel begins to run out.
After draining, tighten the drain plug by hand.

Fuel pump shut off system (except hybrid vehicle [gasoline engine only])
Follow the procedure below to restart the engine after the system is
activated.
Vehicles without a smart entry & start system:
Turn the engine switch to the “ACC” or “LOCK” position.
Restart the engine.
Vehicles with a smart entry & start system:
Turn the “ENGINE START STOP” switch to ACCESSORY mode
or turn it off.
Restart the engine.
NOTICE
Before starting the engine
Inspect the ground under the vehicle.
If you find that fuel has leaked onto the ground, the fuel system has been
damaged and is in need of repair. Do not restart the engine.
To minimize the risk of fuel leakage when the engine stalls or when
an airbag inflates upon collision, the fuel pump shut off system
stops the supply of fuel to the engine.

Vehicles with a DPF system:
Replace the engine oil and oil filter when the engine oil change reminder
light does not come on even if you have driven over 15000 km (9300 miles)
after the engine oil was changed.
There is a possibility that the engine oil change reminder light has been illu-
minated when you have driven less than 15000 km (9300 miles) based on a
usage or driving condition.
CAUTION
When the electric power steering system warning light comes on
The steering wheel may become extremely heavy.
If the steering wheel becomes heavier than usual when operating, hold
firmly and operate using more force than usual.
When driving to clean the DPF catalytic converter
When driving, pay sufficient attention to weather, road conditions, terrain and
traffic conditions, and be sure to observe traffic laws and/or regulations. Fail-
ure to do so may cause an unexpected accident, resulting in death or seri-
ous injury.
NOTICE
If the fuel filter warning light comes on (diesel engine only)
Never drive the vehicle with the warning light on. Continued driving with
water accumulated in the fuel filter will damage the fuel injection pump.
When the DPF system warning light comes on (diesel engine with a
DPF system)
If the DPF system warning light is left on without performing cleaning, after
an additional 100 to 300 km (62 to 187 miles), the malfunction indicator lamp
may come on. If this happens, have the vehicle inspected by any authorized
Toyota dealer or repairer, or another duly qualified and equipped profes-
sional immediately.
