Before driving

CAUTION
Road accident cautions
If your vehicle is involved in an accident, observe the following precautions
to reduce the risk of death or serious injury:
Stop the vehicle in a safe place to prevent subsequent accidents, shift the
shift lever to P, apply the parking brake, and turn the hybrid system off.
(P. 237, 242)
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 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 an electricity leakage leading to a fire. (P. 549)
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 and contact any authorized Toyota dealer
or repairer, or another duly qualified and equipped professional.
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.

NOTICE
When encountering flooded roads
Do not drive on a road that has flooded after heavy rain etc. Doing so may
cause the following serious damage to the vehicle:
Engine stalling
Short in electrical components
Engine damage caused by water immersion
In the event that you drive on a flooded road and the vehicle is flooded, be
sure to have any authorized Toyota dealer or repairer, or another duly quali-
fied and equipped professional check the following:
Brake function
Except hybrid vehicle: Changes in quantity and quality of engine oil, trans-
mission fluid, etc.
Hybrid vehicle: Changes in quantity and quality of oil and fluid used for the
engine, hybrid transmission, etc.
Lubricant condition for the bearings and suspension joints (where possi-
ble), and the function of all joints, bearings, etc.
318 2-4. Using other driving systems
YARIS_F (including HV)_WE_52D27EIf 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.

Does your vehicle need repairs?
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.

Maintenance and care
YARIS_F (including HV)_WE_52D27E
CAUTION
The engine compartment contains many mechanisms and fluids that may
move suddenly, become hot, or become electrically energized. To avoid death
or serious injury, observe the following precautions:
When working on the engine compartment:
On hybrid vehicles, make sure that the engine switch is in the “LOCK”
position (vehicles without an electronic key) or the “POWER” switch off
(vehicles with an electronic key) and the “READY” indicator are both off.
Keep hands, clothing and tools away from the moving fan and engine
drive belt.
Be careful not to touch the engine, power control unit (hybrid vehicle), radi-
ator, exhaust manifold, etc. right after driving as they may be hot. Oil and
other fluids may also be hot.
Do not leave anything that may burn easily, such as paper and rags, in the
engine compartment.
Do not smoke, cause sparks or expose an open flame to fuel or the bat-
tery. Fuel and battery fumes are flammable.
Be extremely cautious when working on the battery. It contains poisonous
and corrosive sulfuric acid.
Take care because brake fluid can harm your hands or eyes and damage
painted surfaces. If fluid gets on your hands or in your eyes, flush the
affected area with clean water immediately.
If you still experience discomfort, consult a doctor.

NOTICE
If you remove the air cleaner filter
Driving with the air cleaner filter removed may cause excessive engine wear
due to dirt in the air.
If the fluid level is low or high
It is normal for the brake fluid level to go down slightly as the brake pads
wear or when the fluid level in the accumulator is high.
If the reservoir needs frequent refilling, it may indicate a serious problem.
