2014 TOYOTA AURIS HYBRID engine

3784-5. Using the driving support systems
UK_AURIS/AURIS_HV_EE (OM12G88E)Reduced effectiveness of the EPS system
Except hybrid model: The effectiveness of the EPS system is reduced to pre-
vent the system from overheating when there is frequent steering input over
an extended period of time. The steering wheel may feel heavy as a result.
Should this occur, refrain from excessive steering input or stop the vehicle
and turn the engine off. The EPS system should return to normal within 10
minutes.
Hybrid model: The effectiveness of the EPS system is reduced to prevent the
system from overheating when there is frequent steering input over an
extended period of time. The steering wheel may feel heavy as a result.
Should this occur, refrain from excessive steering input or stop the vehicle
and turn the hybrid system off. The EPS system should return to normal
within 10 minutes.
Operating conditions of emergency brake signal
When the following three conditions are met, the emergency brake signal will
operate:
The emergency flashers are off.
Actual vehicle speed is over 55 km/h (35 mph).
The brake pedal is depressed in a manner that cause the system to judge
from the vehicle deceleration that this is a sudden braking operation.
Automatic system cancelation of emergency brake signal
The emergency brake signal will turn off in any of the following situations:
The emergency flashers are turned on.
The brake pedal is released.
The system judges from the vehicle deceleration that is not a sudden brak-
ing operation.
CAUTION
The ABS does not operate effectively when
The limits of tire gripping performance have been exceeded (such as
excessively worn tires on a snow covered road).
The vehicle hydroplanes while driving at high speed on wet or slick roads.

Cleaning the DPF catalytic converter
Cleaning the DPF catalytic converter is performed as necessary in
accordance with driving conditions.
Equipment characteristics
The DPF system has the following characteristics:
Idle speed increases during cleaning
The smell of the exhaust gas changes
When starting the engine, white-colored steam (water vapor)
may be expelled during cleaning
Acceleration performance may degrade during cleaning
Replacing the engine oil
P. 513
Diesel particulate filter system (diesel
engine only)
When the deposit collected by the filter reaches a predetermined
amount, it is automatically cleaned.
CAUTION
Exhaust pipe
Do not touch the exhaust pipe during cleaning, as the exhaust pipe and
exhaust gases will become particularly hot. Also, make sure that there are
no people or flammable materials near the exhaust pipe while the vehicle is
stopped.
Failure to do so may cause injury by burning or a fire.

NOTICE
To prevent the DPF system from failing
Do not use fuel other than the specified type
Do not use engine oil other than the recommended type
Do not modify the exhaust pipe

Driving
Air conditioning
Use the air conditioning only when necessary. Doing so can help
control excessive gasoline consumption.
In summer: In high temperatures, use the recirculated air mode.
Doing so will help to reduce the burden on the air conditioner and
reduce fuel consumption as well.
In winter: Because the gasoline engine will not automatically cut out
until the gasoline engine and the interior of the vehicle are warm, it
will consume fuel. Also, fuel consumption can be improved by
avoiding overuse of the heater.
Checking tire inflation pressure
Make sure to check the tire inflation pressure frequently. Improper
tire inflation pressure can cause poor fuel consumption.
Also, as snow tires can cause large amounts of friction, their use on
dry roads can lead to poor fuel consumption. Use a tire that is
appropriate for the season.
Luggage
Carrying heavy luggage can lead to poor fuel consumption. Avoid
carrying unnecessary luggage. Installing a large roof rack can also
cause poor fuel consumption.
Warming up before driving
Since the gasoline engine starts up and cuts out automatically
when cold, warming up the engine is unnecessary. Moreover, fre-
quently driving short distances will cause the engine to repeatedly
warm up, which can lead to poor fuel consumption.

3864-6. Driving tips
UK_AURIS/AURIS_HV_EE (OM12G88E)
Use fluids that are appropriate to the prevailing outside tempera-
tures.
• Engine oil
• Engine coolant
• Power control unit coolant (hybrid model)
• Washer fluid
Have a service technician inspect the condition of the 12-volt bat-
tery.
Have the vehicle fitted with four snow tires or purchase a set of tire
chains for the front tires.
Ensure that all tires are the specified size and brand, and that chains
match the size of the tires.
Winter driving tips
Carry out the necessary preparations and inspections before
driving the vehicle in winter. Always drive the vehicle in a man-
ner appropriate to the prevailing weather conditions.

Driving
CAUTION
Driving with snow tires
Observe the following precautions to reduce the risk of accidents.
Failure to do so may result in a loss of vehicle control and cause death or
serious injury.
Use tires of the specified size.
Maintain the recommended level of air pressure.
Do not drive at speeds in excess of the speed limit or the speed limit spec-
ified for the snow tires being used.
Use snow tires on all, not just some wheels.
Driving with tire chains
Observe the following precautions to reduce the risk of accidents.
Failure to do so may result in the vehicle being unable to be driven safely,
and may cause death or serious injury.
Do not drive in excess of the speed limit specified for the tire chains being
used, or 50 km/h (30 mph), whichever is lower.
Avoid driving on bumpy road surfaces or over potholes.
Avoid sudden acceleration, abrupt steering, sudden braking and shifting
operations that cause sudden engine braking.
Slow down sufficiently before entering a curve to ensure that vehicle con-
trol is maintained.
NOTICE
Repairing or replacing snow tires (vehicles with a tire pressure warn-
ing system)
Request repairs or replacement of snow tires from Toyota dealers or legiti-
mate tire retailers.
This is because the removal and attachment of snow tires affects the opera-
tion of the tire pressure warning valves and transmitters.
Fitting tire chains (vehicles with a tire pressure warning system)
The tire pressure warning valves and transmitters may not function correctly
when tire chains are fitted.

Fogging up of the windows
The windows may fog up if the recirculated air mode is used.
Outside/recirculated air mode
When driving on dusty roads such as tunnels or in heavy traffic, set the out-
side/recirculated air mode button to the recirculated air mode. This is effective
in preventing outside air from entering the vehicle interior.

Interior features
Operation of the air conditioning system in Eco drive mode (hybrid
model)
In Eco drive mode, the air conditioning system is controlled as follows to pri-
oritize fuel efficiency:
Engine speed and compressor operation controlled to restrict heating/cool-
ing 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
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 wind-
shield effectively.
If you turn off, the windows may fog up more easily.
The windows may fog up if the recirculated air mode is used.
Outside/recirculated air mode
When driving on dusty roads such as tunnels or in heavy traffic, set the out-
side/recirculated air mode button to the recirculated air mode. This is effec-
tive in preventing outside air from entering the vehicle interior. During
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 is low
The dehumidification function may not operate even when is pressed.
