NOTICE
To prevent damage to the engine and its components
Vehicles with a tachometer: Do not let the indicator needle of the tachome-
ter enter the red zone, which indicates the maximum engine speed.
The engine may be overheating if the high engine coolant temperature
warning light flashes or turns on. In this case, immediately stop the vehicle
in a safe place, and check the engine after it has cooled completely.

*2: Hybrid vehicle: These lights turn on when the engine switch is
turned to the “ON” position (vehicles without an electronic key) or
the “POWER” switch is turned to ON mode (vehicles with an elec-
tronic key) to indicate that a system check is being performed. They
will turn off after the hybrid system on, or after a few seconds. There
may be a malfunction in a system if a light does not come on, or if
the lights do not turn off. Have the vehicle inspected by any autho-
rized Toyota dealer or repairer, or another duly qualified and
equipped professional.
*3: The light turns on when the engine coolant temperature is low.
*4: The light flashes to indicate that the system is operating.
Warning lights
Warning lights inform the driver of malfunctions in any of the
vehicle’s systems. (P. 561)

YARIS_F(including HV)_WE_52E26EIf the Stop & Start cancel switch is pressed while the vehicle is
stopped
When the engine is stopped by the Stop & Start system, press-
ing the Stop & Start cancel switch will restart the engine.
From the next time the vehicle is stopped (after Stop & Start sys-
tem has been turned off), the engine will not be stopped.
With the Stop & Start system disabled, pressing the Stop & Start
cancel switch will re-enable the system but not stop the engine.
From the next time the vehicle is stopped (after Stop & Start sys-
tem has been turned on), the engine will be stopped.
Operating conditions
The Stop & Start system is operational when all of the following condi-
tions are met:
• The engine is adequately warmed up.
• The battery is sufficiently charged.
• The driver’s door is closed.
• Vehicles with a Multidrive: The driver’s seat belt is fastened.
• The hood is closed.
• The accelerator pedal is not being depressed.
• The shift lever is not in R.
In the following circumstances the engine may not be stopped by the
Stop & Start system. This is not a malfunction of the Stop & Start system.
• Engine coolant temperature or transmission fluid temperature is too
low or too high.
• The air conditioning system is being used when the vehicle interior
temperature is extremely high such as after the vehicle was parked
under the hot sun.
• Vehicles with an automatic air conditioning system only: The wind-
shield defogger is being used.
• The battery is not sufficiently charged, or is undergoing a periodic
recharge.
• Due to traffic or other circumstances the vehicle is stopped repeatedly,
resulting in the amount of time the engine is stopped by the Stop &
Start system to become excessively high.
• The brake pedal is not depressed firmly.

• The vehicle is stopped on a steep hill.
• The brake booster vacuum is low.
• A large amount of electricity is being used.
• At high altitude.
When the above conditions improve, the Stop & Start system will stop and
restart the engine from the next time the vehicle is stopped.
In the following situations, the engine may start even without the brake
pedal being released (vehicles with a Multidrive) or clutch pedal being
depressed (vehicles with a manual transmission).
• The brake pedal is pumped or strongly depressed.
• The air conditioning system is being used or turned on.
• Vehicles with an automatic air conditioning system only: The wind-
shield defogger is turned on.
• The battery is not sufficiently charged.
• The vehicle starts to roll on an incline.
• Vehicles with a Multidrive: The hood is opened when the shift lever is in
N or P.
• The accelerator pedal is depressed.
• A large amount of electricity is being used.
• Vehicles with a Multidrive: The driver’s door is opened.
• Vehicles with a Multidrive: The driver’s seat belt is unfastened.
In the following situations, it may take longer than normal for the Stop &
Start system to activate.
• The battery is discharged.
• After the battery terminals have been disconnected and reconnected
after a battery replacement, etc.
• The engine coolant temperature is low.
Automatic reactivation of the Stop & Start system
Vehicles without a smart entry & start system:
Even if the Stop & Start system is disabled by the Stop & Start cancel switch,
it will be automatically re-enabled once the engine switch is turned to the
“LOCK” position then to the “START” position.
Vehicles with a smart entry & start system:
Even if the Stop & Start system is disabled by the Stop & Start cancel switch,
it will be automatically re-enabled once the “ENGINE START STOP” switch
is turned off then the engine is started.

350 2-5. Driving information
YARIS_F(including HV)_WE_52E26ETransmission information
Vehicles with a Multidrive and multi-mode manual transmission:
To maintain engine braking efficiency, when using engine braking,
do not use the transmission in D. Transmission shift gear position
must be in 4 in the M mode. (P. 253, 258)
Vehicles with a manual transmission:
To maintain engine braking efficiency, when using engine braking,
do not use the transmission in 5 and 6 (vehicles with a 6-speed
manual transmission) gear. (P. 263)
If the engine overheats
Towing a loaded trailer up a long, steep incline in temperatures
exceeding 30C (85F) may result in the engine overheating. If the
high engine coolant temperature warning light flashes or comes
on, turn the air conditioning off immediately, leave the road and
stop the vehicle in a safe place. (P. 642)
When parking the vehicle
Always place wheel chocks under the wheels of both the vehicle
and trailer. Firmly set the parking brake and shift the shift lever to P
for Multidrives, E, M or R for multi-mode manual transmissions,
and 1 or R for manual transmissions.

Be on the alert for changes in performance and sounds, and visual tip-offs
that indicate service is needed. Some important clues are:
Engine misses, stumbling, or pinging
Appreciable loss of power
Strange engine noises
A fluid leak under the vehicle (However, water dripping from the air condi-
tioning system after use is normal.)
Change in exhaust sound (This may indicate a dangerous carbon mon-
oxide leak. Drive with the windows open and have the exhaust system
checked immediately.)
Flat-looking tires, excessive tire squeal when cornering, uneven tire wear
Vehicle pulls to one side when driving straight on a level road
Strange noises related to suspension movement
Loss of brake effectiveness, spongy feeling brake pedal or clutch pedal
(vehicles with a manual transmission), pedal almost touches the floor,
vehicle pulls to one side when braking
Engine coolant temperature continually higher than normal
If you notice any of these clues, take your vehicle to any authorized Toyota
dealer or repairer, or another duly qualified and equipped professional as
soon as possible. Your vehicle may need adjustment or repair.

Coolant selection
Only use “Toyota Super Long Life Coolant” or a similar high quality ethylene
glycol based non-silicate, non-amine, non-nitrite, and non-borate coolant
with long-life hybrid organic acid technology.
“Toyota Super Long Life Coolant” is a mixture of 50% coolant and 50%
deionized water. (Minimum temperature: -35C [-31F])
For more details about engine coolant, contact any authorized Toyota dealer
or repairer, or another duly qualified and equipped professional.
If the coolant level drops within a short time of replenishing
Except hybrid vehicle: Visually check the radiator, hoses, engine coolant res-
ervoir cap, drain cock and water pump.
Hybrid vehicle: Visually check the radiator, hoses, engine/power control unit
coolant reservoir caps, drain cock and water pump.
If you cannot find a leak, have any authorized Toyota dealer or repairer, or
another duly qualified and equipped professional, test the cap and check for
leaks in the cooling system.
CAUTION
When the engine is hot (except hybrid vehicle)
Do not remove the radiator cap (gasoline engine), or the engine coolant res-
ervoir cap (diesel engine).
The cooling system may be under pressure and may spray hot coolant if the
cap is removed, causing serious injuries, such as burns.
When the hybrid system is hot (hybrid vehicle)
Do not remove the engine/power control unit coolant reservoir caps.
The cooling system may be under pressure and may spray hot coolant if the
cap is removed, causing serious injuries, such as burns.
