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
When the VSC is activated
The slip indicator light flashes. Always drive carefully. Reckless driving may
cause an accident. Exercise particular care when the indicator light flashes.
When the TRC/VSC systems are turned off (except hybrid vehicle)
Be especially careful and drive at a speed appropriate to the road condi-
tions. Do not turn the TRC/VSC systems off unless necessary, as these are
the systems to ensure vehicle stability and driving force by automatically
controlling braking and engine outputs.
Replacing tires
Make sure that all tires are of the specified size, brand, tread pattern and
total load capacity. In addition, make sure that the tires are inflated to the
recommended tire inflation pressure level.
The ABS, TRC and VSC systems will not function correctly if different tires
are installed on the vehicle.
Contact any authorized Toyota dealer or repairer, or another duly qualified
and equipped professional for further information when replacing tires or
wheels.
Handling of tires and the suspension
Using tires with any kind of problem or modifying the suspension will affect
the driving assist systems, and may cause a system to malfunction.

Check for and remove any excess ice or snow that may have
accumulated on the exterior lights, vehicle’s roof, chassis,
around the tires or on the brakes.
Remove any snow or mud from the bottom of your shoes
before getting in the vehicle.
When driving the vehicle
Accelerate the vehicle slowly, keep a safe distance between you
and the vehicle ahead, and drive at a reduced speed suitable to
road conditions.
When parking the vehicle (in the winter time or in the cold
latitudes)
Park the vehicle and move the shift lever to P (vehicles with a
hybrid transmission or a Multidrive), E, M or R (vehicles with a
multi-mode manual transmission), and 1 or R (vehicles with a
manual transmission) without setting the parking brake. The
parking brake may freeze up, preventing it from being released.
If necessary, block the wheels to prevent inadvertent sliding or
creeping.

(0.12 in.) in diameter
175/65R14 tires: 4 mm (0.16
in.) in diameter
Cross chain
Except 175/65R14 tires: 4 mm
(0.16 in.) in diameter
175/65R14 tires: 5 mm (0.20
in.) in diameter
Regulations on the use of tire chains
Regulations regarding the use of tire chains vary depending on loca-
tion and type of road. Always check local regulations before installing
chains.
Tire chain installation
Observe the following precautions when installing and removing chains:
Install and remove tire chains in a safe location.
Install tire chains on the front tires only. Do not install tire chains on the
rear tires.
Install tire chains on front tires as tightly as possible. Retighten chains
after driving 0.5  1.0 km (1/4  1/2 mile).
Install tire chains following the instructions provided with the tire chains.
If wheel ornaments are used, they will be scratched by the chain band,
so remove the ornaments before putting on the chains. (P. 585)

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.

Trailer towing (hybrid vehicle)
Toyota does not recommend towing a trailer with your vehicle. Toy-
ota also does not recommend the installation of a tow hitch or the
use of a tow hitch carrier for a wheelchair, scooter, bicycle, etc. Your
vehicle is not designed for trailer towing or for the use of tow hitch
mounted carriers.

350 2-5. Driving information
YARIS_F (including HV)_WE_52C79E
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.

352 2-5. Driving information
YARIS_F (including HV)_WE_52C79E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. 255, 260)
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. 265)
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. 635)
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.
