CAUTION
Caution while towing
Use extreme caution when towing the vehicle.
Avoid sudden starts or erratic driving maneuvers which place excessive
stress on the emergency towing eyelet and the cable or chain. Always be
cautious of the surroundings and other vehicles while towing.
Except hybrid vehicle (vehicles without a smart entry & start system): Do
not turn the engine switch to the “LOCK” position.
Except hybrid vehicle (vehicles with a smart entry & start system): Do not
turn the “ENGINE START STOP” switch off.
Doing so will lock the steering wheel and prevent operation, possibly caus-
ing an accident and resulting in death or serious injury.
Hybrid vehicle (vehicles without an electronic key): Do not turn the engine
switch to the “LOCK” position.
Hybrid vehicle (vehicles with an electronic key): Do not turn the “POWER”
switch off.
This may lead to accidents because the steering wheel will be locked and
you will not be able to operate the steering wheel.
Except hybrid vehicle: If the engine is not running, the power assist for the
brakes and steering will not function, making steering and braking more
difficult.
Hybrid vehicle: If the hybrid system is off, the power assist for the brakes
and steering will not function, making steering and braking more difficult.
Installing towing eyelet to the vehicle
Make sure that towing eyelet is installed securely.
If not securely installed, towing eyelet may come loose during towing. This
may lead to accidents that cause serious injury or even death.

Passenger detection sensor and passenger seat belt reminder
If luggage is placed on a passenger seat, the passenger detection sensor
may cause the warning light to flash even if a passenger is not sitting in
the seat.
If a cushion is placed on the seat, the sensor may not detect a passen-
ger, and the warning light may not operate properly.
Electric power steering warning light (warning buzzer)
Except hybrid vehicle: When the battery charge becomes insufficient or the
voltage temporarily drops, the electric power steering system warning light
may come on and the warning buzzer may sound.
Hybrid vehicle: When the 12-volt battery charge becomes insufficient or the
voltage temporarily drops, the electric power steering system warning light
may come on and the warning buzzer may sound.
If the malfunction indicator lamp comes on while driving
For some models, the malfunction indicator lamp will come on if the fuel tank
becomes completely empty. If the fuel tank is empty, refuel the vehicle
immediately. The malfunction indicator lamp will go off after several trips.
If the malfunction indicator lamp does not go off, contact any authorized
Toyota dealer or repairer, or another duly qualified and equipped profes-
sional as soon as possible.
If the engine oil change reminder light flashes (diesel engine with a
DPF system)
Repeated short trips and/or low-speed driving may cause the oil to degrade
sooner than usual, regardless of the actual distance driven. If this happens,
the engine oil change reminder light will flash.
Engine oil change reminder light comes on (diesel engine only)
Vehicles without 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 40000 km (25000 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 40000 km (25000 miles) based on
a usage or driving condition.

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.

CAUTION
If the engine has to be turned off while driving (except hybrid vehicle)
Power assist for the brakes and steering wheel will be lost, making the
brake pedal harder to depress and the steering wheel heavier to turn.
Decelerate as much as possible before turning off the engine.
Vehicles without a smart entry & start system: Never attempt to remove
the key, as doing so will lock the steering wheel.
If the hybrid system has to be turned off while driving (hybrid vehicle)
Power assist for the brakes and steering wheel will be lost, making the
brake pedal harder to depress and the steering wheel heavier to turn.
Decelerate as much as possible before turning off the hybrid system.
Vehicles without an electronic key: Never attempt to remove the key, as
doing so will lock the steering wheel.
Except hybrid vehicle (vehi-
cles with a smart entry & start
system): To stop the engine,

START STOP” switch for 3
consecutive seconds or more,
or press it briefly 3 times or
more in succession.
