pended if the hybrid system is turned on and off repeatedly in a short period
of time. In this case, refrain from operating the hybrid system. After about 10
seconds, the steering lock motor will resume functioning.
Check that the shift lever is securely set
in P. The hybrid system may not start if
the shift lever is displaced out of P. The
smart entry & start system indicator light
(green) will flash quickly.

The Stop & Start system protection feature
Vehicles without a smart entry & start system:
When an excessively loud sound is being projected by the audio system, the
audio system may be automatically cut off in order to maintain power for the
Stop & Start system function.
If this occurs, turning the engine switch to the “LOCK” position then to the
“ACC” or “ON” position re-enables the audio system.
Vehicles with a smart entry & start system:
When an excessively loud sound is being projected by the audio system, the
audio system may be automatically cut off in order to maintain power for the
Stop & Start system function.
If this occurs, turning the “ENGINE START STOP” switch off then to ACCES-
SORY mode or IGNITION ON mode re-enables the audio system.
Steering wheel operation
When the engine is stopped by the Stop & Start system, the steering wheel
may become heavier than when driving.
Hood
If the hood is opened while the engine is stopped by the Stop & Start system,
the engine cannot be restarted by the Stop & Start system or by the auto-
matic engine start function. Restart the engine with the engine switch opera-
tion. (P. 224, 228)
Vehicles with a Multidrive: If the hood is opened while the engine is stopped
by the Stop & Start system and the shift lever is in N or P, the engine will
restart.
Hill-start assist control (vehicles with a Multidrive)
On a steep uphill grade, the vehicle may roll backward after hill-start
assist control is released. In this situation, apply the parking brake and
operate the brake pedal when putting the vehicle in motion.
This system operates on flat surfaces as well as steep grades.
When the engine is stopped due to Stop & Start system operation, the
force required to depress the brake pedal may change, but this is not a
malfunction.
When to use the Stop & Start system
Use the Stop & Start system when stopping the vehicle temporarily at red
lights, intersections, etc. When stopping the vehicle for a longer period of
time, turn off the engine completely.

Driving assist systems
To help enhance driving safety and performance, the following sys-
tems operate automatically in response to various driving situations.
Be aware, however, that these systems are supplementary and
should not be relied upon too heavily when operating the vehicle.
ABS (Anti-lock Brake System)
Helps to prevent wheel lock when the brakes are applied suddenly, or if
the brakes are applied while driving on a slippery road surface
Brake assist
Generates an increased level of braking force after the brake pedal is
depressed when the system detects a panic stop situation
VSC (Vehicle Stability Control) (if equipped)
Helps the driver to control skidding when swerving suddenly or turning
on slippery road surfaces
TRC (Traction Control) (if equipped)
Helps to maintain drive power and prevent the drive wheels from spin-
ning when starting the vehicle or accelerating on slippery roads
Hill-start assist control
Except hybrid vehicle (vehicles with a Stop & Start system and a
Multidrive)
Helps to prevent the vehicle from rolling backward when the brake
pedal is released to restart the engine
Hybrid vehicle
P. 332
EPS (Electric Power Steering)
Employs an electric motor to reduce the amount of effort needed to turn
the steering wheel

Hill-start assist control operation conditions (except hybrid vehicle)
The shift lever is in D or M.
The brake pedal is not depressed.
When the “TRC OFF” indicator light comes on even if the VSC OFF
switch has not been pressed (except hybrid vehicle)
TRC and hill-start assist control cannot be operated. Contact any authorized
Toyota dealer or repairer, or another duly qualified and equipped profes-
sional.
Sounds and vibrations caused by the ABS, brake assist, TRC and VSC
systems
A sound may be heard from the engine compartment when the brake
pedal is depressed repeatedly, when the engine is started or just after the
vehicle begins to move. This sound does not indicate that a malfunction
has occurred in any of these systems.
Any of the following conditions may occur when the above systems are
operating. None of these indicates that a malfunction has occurred.
• Vibrations may be felt through the vehicle body and steering.
• A motor sound may be heard after the vehicle comes to a stop.
• The brake pedal may pulsate slightly after the ABS is activated.
• The brake pedal may move down slightly after the ABS is activated.
EPS operation sound
When the steering wheel is operated, a motor sound (whirring sound) may
be heard. This does not indicate a malfunction.
Reactivation of the TRC/VSC systems after turning off the engine
(except hybrid vehicle)
Even after the TRC/VSC systems have been turned off, turning the engine
off and then on again will automatically reactivate the TRC/VSC systems.
Reactivation of the TRC system linked to vehicle speed (except hybrid
vehicle)
When only the TRC system is turned off, the TRC system will turn on when
vehicle speed increases. However, when both TRC and VSC systems are
turned off, the systems will not turn on even when vehicle speed increases.

Reduced effectiveness of the EPS system
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 engine
(except hybrid vehicle) or hybrid system (hybrid vehicle) off. The EPS sys-
tem should return to normal within 10 minutes.
If the slip indicator comes on
It may indicate a malfunction in the driving assist systems. Contact any
authorized Toyota dealer or repairer, or another duly qualified and equipped
professional.
CAUTION
The ABS does not operate effectively when
Tires with inadequate gripping ability are used (such as excessively worn
tires on a snow covered road).
The vehicle hydroplanes while driving at high speed on wet or slick roads.
Stopping distance when the ABS is operating may exceed that of nor-
mal conditions
The ABS is not designed to shorten the vehicle’s stopping distance. Always
maintain a safe distance from the vehicle in front of you in the following situ-
ations:
When driving on dirt, gravel or snow-covered roads
When driving with tire chains
When driving over bumps in the road
When driving over roads with potholes or roads with uneven surfaces
TRC may not operate effectively when
Directional control and power may not be achievable while driving on slip-
pery road surfaces, even if the TRC system is operating.
Do not drive the vehicle in conditions where stability and power may be lost.
Hill-start assist control does not operate effectively when
Do not overly rely on the hill-start assist control. The hill-start assist control
may not operate effectively on steep inclines and roads covered with ice.

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.
Do not use tires of noticeably different wear level.
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 to engine braking.
Slow down sufficiently before entering a curve to ensure that vehicle con-
trol is maintained.

Guidance
Your vehicle will handle differently when towing a trailer. In order to
avoid accident, death or serious injury, keep the following in mind
when towing:
Checking connections between trailer and lights
Stop the vehicle and check the operation of the connection
between the trailer and lights after driving for a brief period as well
as before starting off.
Practicing driving with a coupled trailer
Get the feel for turning, stopping and reversing with the trailer
coupled by practicing in an area with no or light traffic.
When reversing with a coupled trailer, hold the section of the
steering wheel nearest to you and rotate clockwise to turn the
trailer left or counterclockwise to turn it right. Always rotate a lit-
tle at a time to prevent steering error. Have someone guide you
when reversing to lessen the risk of an accident.
NOTICE
When the rear bumper strengthening material is aluminum
Ensure the steel bracket part does not come directly in contact with that
area.
When steel and aluminum come into contact, there is a reaction similar to
corrosion, which will weaken the section concerned and may result in dam-
age. Apply a rust inhibitor to parts that will come in contact when attaching a
steel bracket.

When driving
YARIS_F (including HV)_WE_52C79EIncreasing vehicle-to-vehicle distance
At a speed of 10 km/h (6 mph), the distance to the vehicle running
ahead of you should be equivalent to or greater than the combined
length of your vehicle and trailer. Avoid sudden braking that may
cause skidding. Otherwise, the vehicle may spin out of control.
This is especially true when driving on wet or slippery road sur-
faces.
Sudden acceleration/steering input/cornering
Executing sharp turns when towing may result in the trailer collid-
ing with your vehicle. Decelerate well in advance when approach-
ing turns and take them slowly and carefully to avoid sudden
braking.
Important points regarding turning
The wheels of the trailer will travel closer to the inside of the curve
than the wheels of the vehicle. To make allowance for this, take the
turns wider than you would normally do.
Important points regarding stability
Vehicle movement resulting from uneven road surfaces and strong
crosswinds will affect handling. The vehicle may also be rocked by
passing buses or large trucks. Frequently check behind when mov-
ing alongside such vehicles. As soon as such vehicle movement
occurs, immediately start to decelerate smoothly by slowly apply-
ing the brakes. Always steer the vehicle straight ahead while brak-
ing.
Passing other vehicles
Consider the total combined length of your vehicle and trailer and
ensure that the vehicle-to-vehicle distance is sufficient before exe-
cuting lane changes.
