119 2-1. Driving procedures

When driving
AYGO_WE_99G80E
CAUTION
Do not shift the shift lever to R while the vehicle is moving forward.
Doing so can damage the transmission and may result in a loss of vehicle
control.
Do not shift the shift lever to E or M (vehicles with a multi-mode manual
transmission), or 1 (vehicles with a manual transmission) while the vehicle
is moving backward.
Doing so can damage the transmission and may result in a loss of vehicle
control.
Moving the shift lever to N while the vehicle is moving will disengage the
engine from the transmission. Engine braking is not available when N is
selected.
During normal driving, do not turn off the engine. Turning the engine off
while driving will not cause loss of steering or braking control, but the
power assist to these systems will be lost. This will make it more difficult to
steer and brake, so you should pull over and stop the vehicle as soon as it
is safe to do so.
However, in the event of an emergency, such as if it becomes impossible
to stop the vehicle in the normal way: P. 342
Use engine braking (downshift) to maintain a safe speed when driving
down a steep hill.
Using the brakes continuously may cause the brakes to overheat and lose
effectiveness. (P. 129, 134)
When stopped on an inclined surface, use the brake pedal and parking
brake to prevent the vehicle from rolling backward or forward and causing
an accident.
Do not adjust the positions of the steering wheel, the seat, or the inside or
outside rear view mirrors while driving.
Doing so may result in a loss of vehicle control that can cause accidents,
resulting in death or serious injury.
Always check that all passengers’ arms, heads or other parts of their body
are not outside the vehicle, as this may result in death or serious injury.

120 2-1. Driving procedures
AYGO_WE_99G80E
CAUTION
When driving on slippery road surfaces
Sudden braking, acceleration and steering may cause tire slippage and
reduce your ability to control the vehicle, resulting in an accident.
Sudden acceleration, engine braking due to shift changing, or changes in
engine speed could cause the vehicle to skid, resulting in an accident.
After driving through a puddle, lightly depress the brake pedal to make
sure that the brakes are functioning properly. Wet brake pads may prevent
the brakes from functioning properly. If the brakes on only one side are wet
and not functioning properly, steering control may be affected, resulting in
an accident.
When shifting the shift lever (vehicles with a multi-mode manual trans-
mission)
Be careful not to shift the shift lever with the accelerator pedal depressed.
Shifting the shift lever to a gear other than N may lead to unexpected rapid
acceleration of the vehicle that may cause an accident and result in death or
serious injury.
When the vehicle is stopped
Do not race the engine.
If the vehicle is in any gear other than N, the vehicle may accelerate sud-
denly and unexpectedly, causing an accident.
Do not leave the vehicle with the engine running for a long time.
If such a situation cannot be avoided, park the vehicle in an open space
and check that exhaust fumes do not enter the vehicle interior.
On vehicles with a multi-mode manual transmission, in order to prevent
accidents due to the vehicle rolling away, always keep depressing the
brake pedal while the engine is running, and apply the parking brake as
necessary.
If the vehicle is stopped on an incline, in order to prevent accidents caused
by the vehicle rolling forward or backward, always depress the brake pedal
and securely apply the parking brake as needed.
Avoid revving or racing the engine.
Running the engine at high speed while the vehicle is stopped may cause
the exhaust system to overheat, which could result in a fire if combustible
material is nearby.

122 2-1. Driving procedures
AYGO_WE_99G80E
CAUTION
On vehicles with a multi-mode manual transmission, do not turn off the
engine until 1st or reverse is engaged properly and completely. Confirm
that the gear is engaged by viewing the gear position indicator.
Parking the vehicle without a gear engaged may cause the vehicle to
move result in an accident.
Exhaust gases
Exhaust gases include harmful carbon monoxide (CO), which is colorless
and odorless. Inhaling exhaust gases may lead to death or a serious health
hazard.
If the vehicle is in a poorly ventilated area, stop the engine. In a closed
area, such as a garage, exhaust gases may collect and enter the vehicle.
This may lead to death or a serious health hazard.
The exhaust system should be checked occasionally. If there is a hole or
crack caused by corrosion, damage to a joint or abnormal exhaust noise,
be sure to have the vehicle inspected and repaired by any authorized
Toyota dealer or repairer, or another duly qualified and equipped
professional. Failure to do so may allow exhaust gases to enter the
vehicle, resulting in death or a serious health hazard.
When taking a nap in the vehicle
Always turn the engine off. Otherwise, if you accidentally move the shift lever
or depress the accelerator pedal, this could cause an accident or fire due to
engine overheating. Additionally, if the vehicle is parked in a poorly venti-
lated area, exhaust gases may collect and enter the vehicle, leading to
death or a serious health hazard.

128 2-1. Driving procedures
AYGO_WE_99G80E
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.

140 2-2. Instrument cluster
AYGO_WE_99G80E
Changing the display
Switches between odometer and
trip meter displays. When the trip
meter is displayed, pressing and
holding the button will reset the
trip meter.
The meters and display operate when
The engine switch is in the “ON” position.
NOTICE
To prevent damage to the engine and its components
Vehicles with a tachometer: Do not let the indicator needle of the tachome-
ter enter the red zone, which indicates the maximum engine speed.
The engine may be overheating if the high engine coolant temperature
warning light flashes or turns on. In this case, immediately stop the vehicle
in a safe place, and check the engine after it has cooled completely.
(
P. 336)

155 2-4. Using other driving systems
2
When driving
AYGO_WE_99G80E
Sounds and vibrations caused by the ABS, brake assist, VSC and TRC
systems
A sound may be heard from the engine compartment when the engine is
started or just after the vehicle begins to move. This sound does not indi-
cate 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 while the ABS is operating.
• The brake pedal may move down slightly after the ABS is activated.
EPS operation sound
When the steering wheels is operated, a motor sound (whirring sound) may
be heard. This does not indicate a malfunction.
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.
CAUTION
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.
