■ Sounds and vibrations caused by the ABS, brake assist, VSC, TRC, and
hill-start assist control 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 also 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.
■ Automatic reactivation of TRC and VSC systems
After turning the TRC and VSC systems off, the systems will be automatically
re-enabled in the following situations:
● When the engine switch is turned off
● If only the TRC system is turned off, the TRC will turn on when vehicle
speed increases
If both the TRC and VSC systems are turned off, automatic re-enabling will
not occur 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 off. The EPS system should return to normal within 10
minutes.

WARNING
■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.
■ Stopping distance when the ABS is operating may exceed that of nor-
mal conditions
The ABS is not designed to shorten t he vehicle’s stopping distance. Always
maintain a safe distance from the vehicle in front of you, especially in the
following situations:
● When driving on dirt, gravel or snow-covered roads
● When driving over bumps in the road
● When driving over roads with potholes or uneven surfaces
■ TRC/VSC may not operate effectively when
Directional control and power may not be achievable while driving on slip-
pery road surfaces, even if the TRC/VSC system is operating.
Drive the vehicle carefully in conditions where stability and power may be
lost.
■ Hill-start assist control does not operate effectively when
● Do not overly rely on hill-start assist control. Hill-start assist control may
not operate effectively on steep inclines and roads covered with ice.
● Unlike the parking brake, hill-start assist control is not intended to hold the
vehicle stationary for an extended period of time. Do not attempt to use
hill-start assist control to hold the vehicle on an incline, as doing so may
lead to an accident.

2426-1. Maintenance and care
YARIS_GRMN_OM_Europe_OM52J40E
Cleaning and protecting the vehicle exterior
●Working from top to bottom, liberally apply water to the vehicle
body, wheel wells and underside of the vehicle to remove any dirt
and dust.
● Wash the vehicle body using a sponge or soft cloth, such as a
chamois.
● For hard-to-remove marks, use car wash soap and rinse thoroughly
with water.
● Wipe away any water.
● Wax the vehicle when the waterproof coating deteriorates.
If water does not bead on a clean surface, apply wax when the vehicle
body is cool.
■ Automatic car washes
● Fold the mirrors and remove the antenna (pole type) before washing the
vehicle. Start washing from the front of the vehicle. Make sure to extend the
mirrors and re-install the antenna before driving.
● Brushes used in automatic car washes may scratch the vehicle surface and
harm your vehicle’s paint.
● Rear spoiler may not be washable in some automatic car washes. There
may also be an increased risk of damage to vehicle.
■ High pressure car washes
● Do not allow the nozzles of the car wash to come within close proximity of
the windows and door borders, and high mounted stoplight.
● Before using the car wash, check that the fuel filler door on your vehicle is
closed properly.
■ When using a car wash
If the door handle becomes wet while the electronic key is within the effective
range, the door may lock and unlock repeatedly. Place the key in a position
2 m (6 ft.) or more separate from the vehicle while the vehicle is being
washed. (Take care to ensure that the key is not stolen.)
Perform the following to protect the vehicle and maintain it in
prime condition:

Fuel pump shut off system
Follow the procedure below to restart the engine after the system is
activated.
Turn the engine switch to ACCESSORY mode or turn it off.
Restart the engine.
To minimize the risk of fuel leakage when the engine stalls or
when an airbag inflates upon collision, the fuel pump shut off
system stops the supply of fuel to the engine.
NOTICE
■ Before starting the engine
Inspect the ground under the vehicle.
If you find that fuel has leaked onto the ground, the fuel system has been
damaged and is in need of repair. Do not restart the engine.

Start the engine of the second vehicle. Increase the engine speed
slightly and maintain it at that level for approximately 5 minutes to
recharge the battery of your vehicle.
Open and close any of the doors of your vehicle with the engine
switch off.
Maintain the engine speed of the second vehicle and turn the
engine switch to IGNITION ON mode, then start the vehicle’s
engine.
Once the vehicle’s engine has started, remove the jumper cables in
the exact reverse order from which they were connected.
Once the engine starts, have the vehicle inspected at any authorized
Toyota retailer or Toyota authorized repairer, or any reliable repairer
as soon as possible.
■ To prevent battery discharge
● Turn off the headlights and the audio system while the engine is stopped.
● Turn off any unnecessary electrical components when the vehicle is running
at a low speed for an extended period, such as in heavy traffic.
■ Charging the battery
The electricity stored in the battery will discharge gradually even when the
vehicle is not in use, due to natural discharge and the draining effects of cer-
tain electrical appliances. If the vehicle is left for a long time, the battery may
discharge, and the engine may be unable to start. (The battery recharges
automatically during driving.)
■ Precautions when the battery is discharged
● In some cases, it may not be possible to unlock the doors using the smart
entry & start system when the battery is discharged. Use the wireless
remote control or the mechanical key to lock or unlock the doors.
● The engine may not start on the first attempt after the battery has recharged
but will start normally after the second attempt. This is not a malfunction.
● The engine switch mode is memorized by the vehicle. When the battery is
reconnected, the system will return to the mode it was in before the battery
was discharged. Before disconnecting the battery, turn the engine switch off.
If you are unsure what mode the engine switch was in before the battery dis-
charged, be especially careful when reconnecting the battery.

When trouble arises
Add coolant if necessary.
Water can be used in an emer-
gency if coolant is unavailable.
Do not open as coolant may over-
flow when “A” is opened.
Start the engine and turn the air conditioning system on to check
that the radiator cooling fan operates and to check for coolant leaks
from the radiator or hoses.
The fan operates when the air conditioning system is turned on immedi-
ately after a cold start. Confirm that the fan is operating by checking the fan
sound and air flow. If it is difficult to check these, turn the air conditioning
system on and off repeatedly.
(The fan may not operate in freezing temperatures.)
If the fan is not operating:
Stop the engine immediately and contact any authorized Toyota
retailer or Toyota authorized repairer, or any reliable repairer.
If the fan is operating:
Have the vehicle inspected at the nearest authorized Toyota retailer
or Toyota authorized repairer, or any reliable repairer.
