When driving
YARIS_F (including HV)_WE_52C79E
CAUTION
When starting the engine
Always start the engine while sitting in the driver’s seat. Do not depress the
accelerator pedal while starting the engine under any circumstances.
Doing so may cause an accident resulting in death or serious injury.
Caution when driving
Do not turn the engine switch to the “LOCK” position while driving. If, in an
emergency, you must turn the engine off while the vehicle is moving, turn the
engine switch only to the “ACC” position to stop the engine. An accident may
result if the engine is stopped while driving. (P. 650)
NOTICE
To prevent battery discharge
Do not leave the engine switch in the “ACC” or “ON” position for long periods
of time without the engine running.
When starting the engine
Do not crank the engine for more than 30 seconds at a time. This may
overheat the starter and wiring system.
Do not race a cold engine.
If the engine becomes difficult to start or stalls frequently, have your vehi-
cle checked by any authorized Toyota dealer or repairer, or another duly
qualified and equipped professional immediately.

Tire information
Ensure that your vehicle's tires are properly inflated. Adjust the tire pres-
sure to the recommended pressure. (P. 672)
Increase the air pressure of the trailer tires in accordance with the total
trailer weight and according to the values recommended by the manufac-
turer of your trailer.
Trailer lights
Check that the turn signal lights and stoplights are operating correctly every
time you hitch up the trailer. Directly wiring up to your vehicle may damage
the electrical system and stop the lights from functioning correctly.
Break-in schedule
Toyota recommends that vehicles fitted with new power train components
should not be used for towing trailers for the first 800 km (500 miles).
Safety checks before towing
Check that the maximum load limit for the towing hitch/bracket and hitch
ball is not exceeded. Bear in mind that the coupling weight of the trailer
will add to the load exerted on the vehicle. Also make sure that the total
load exerted on the vehicle is within the range of the weight limits.
(P. 344)
Ensure that the trailer load is secure.
Supplementary outside rear view mirrors should be added to the vehicle
if the traffic behind cannot be clearly seen with standard mirrors. Adjust
the extending arms of these mirrors on both sides of the vehicle so that
they always provide maximum visibility of the road behind.
Maintenance
Maintenance must be performed more frequently when using the vehicle
for towing due to the greater weight burden placed on the vehicle com-
pared to normal driving.
Retighten all bolts securing the hitching ball and bracket after towing for
approximately 1000 km (600 miles).

452 4-1. Maintenance and care
YARIS_F (including HV)_WE_52C79E
Caring for leather areas
Toyota recommends cleaning the interior of the vehicle at least twice a year
to maintain the quality of the vehicle’s interior.
Shampooing the carpets
There are several commercial foaming-type cleaners available. Use a
sponge or brush to apply the foam. Rub in overlapping circles. Do not use
water. Wipe dirty surfaces and let them dry. Excellent results are obtained by
keeping the carpet as dry as possible.
Seat belts
Clean with mild soap and lukewarm water using a cloth or sponge. Also
check the belts periodically for excessive wear, fraying or cuts.
CAUTION
Water in the vehicle
Except hybrid vehicle: Do not splash or spill liquid in the vehicle.
Doing so may cause electrical components etc. to malfunction or catch
fire.
Hybrid vehicle: Do not splash or spill liquid in the vehicle, such as on the
floor, in the hybrid battery (traction battery) air vents, and in the rear seat.
Doing so may cause the hybrid battery, electrical components, etc. to mal-
function or catch fire.
Do not get any of the SRS components or wiring in the vehicle interior wet.
(P. 167)
An electrical malfunction may cause the airbags to deploy or not function
properly, resulting in death or serious injury.
Cleaning the interior (especially instrument panel)
Do not use polish wax or polish cleaner. The instrument panel may reflect off
the windshield, obstructing the driver’s view and leading to an accident,
resulting in death or serious injury.

Maintenance and care
YARIS_F (including HV)_WE_52C79E
After a fuse is replaced
If the lights do not turn on even after the fuse has been replaced, a bulb
may need replacement. (P. 535)
If the replaced fuse blows again, have the vehicle inspected by any
authorized Toyota dealer or repairer, or another duly qualified and
equipped professional.
If there is an overload in a circuit
The fuses are designed to blow, protecting the wiring harness from damage.
When replacing light bulbs
Toyota recommends that you use genuine Toyota products designed for this
vehicle. Because certain bulbs are connected to circuits designed to prevent
overload, non-genuine parts or parts not designed for this vehicle may be
unusable.
When reinstalling the cover (type C fuse box cover only)
Left hand drive vehicles
Right hand drive vehicles
Reinstall the cover, and then hook the
rubber strip’s groove onto the cover.

534 4-3. Do-it-yourself maintenance
YARIS_F (including HV)_WE_52C79E
CAUTION
To prevent system breakdowns and vehicle fire
Observe the following precautions.
Failure to do so may cause damage, and possibly a fire or injury.
Never use a fuse of a higher amperage rating than that indicated, or use
any other object in place of a fuse.
Always use a genuine Toyota fuse or equivalent.
Never replace a fuse with a wire, even as a temporary fix.
This can cause extensive damage or even fire.
Do not modify the fuses or fuse boxes.
Fuse box near the power control unit (hybrid vehicle)
Never check or replace the fuses as there are high voltage parts and wiring
near the fuse box.
Doing so may cause electric shock, resulting in death or serious injury.
NOTICE
Before replacing fuses
Have the cause of electrical overload determined and repaired by any autho-
rized Toyota dealer or repairer, or another duly qualified and equipped pro-
fessional as soon as possible.

646 5-2. Steps to take in an emergency
YARIS_F (including HV)_WE_52C79E
NOTICE
When restarting the engine
Do not crank the engine before refueling and operating the priming pump.
This may damage the engine and fuel system.
Vehicles without a smart entry & start system: Do not crank the engine for
more than 30 seconds at a time. This may overheat the starter and wiring
system.
Start the engine. (P. 224, 228)
If the engine does not start after the above steps have been per-
formed, wait for 10 seconds and then try steps 3 and 5 again. If
the engine still does not start, contact any authorized Toyota
dealer or repairer, or another duly qualified and equipped profes-
sional.
After starting the engine, depress the accelerator pedal lightly until
the engine runs smoothly.
