4Maintenance and care5When trouble arises

168 2-1. Driving procedures
iQ_WE_74014E
CAUTION
When starting the vehicle (vehicles with a Multidrive)
Always keep your foot on the brake pedal while stopped with the engine run-
ning. This prevents the vehicle from creeping.
When driving the vehicle
Do not drive if you are unfamiliar with the location of the clutch, brake and
accelerator pedals to avoid depressing the wrong pedal.
• Accidentally depressing the accelerator pedal instead of the brake
pedal will result in sudden acceleration that may lead to an accident
that could result in death or serious injury.
• When backing up, you may twist your body around, leading to a diffi-
culty in operating the pedals. Make sure to operate the pedals properly.
• Make sure to keep a correct driving posture even when moving the
vehicle only slightly, allowing you to depress the brake and accelerator
pedals properly.
• Depress the brake pedal using your right foot. Depressing the brake
pedal using your left foot may delay response in an emergency, result-
ing in an accident.
Do not drive the vehicle over or stop the vehicle near flammable materials.
The exhaust system and exhaust gases can be extremely hot. This may
cause a fire if there is any flammable material nearby.
Do not let the vehicle roll backward while the shift lever is in a driving posi-
tion, or roll forward while the shift lever is in R.
Doing so may cause the engine to stall or lead to poor brake and steering
performance, resulting in an accident or damage to the vehicle.
If the smell of exhaust is noticed inside the vehicle, open the windows and
check that the back door is closed. Large amounts of exhaust in the
vehicle can cause driver drowsiness and an accident, resulting in death or
a serious health hazard. Have the vehicle inspected by any authorized
Toyota dealer or repairer, or another duly qualified and equipped
professional immediately.
On vehicles with a Multidrive, do not shift the shift lever to P while the vehi-
cle is moving.
Doing so can damage the transmission and may result in a loss of vehicle
control.

170 2-1. Driving procedures
iQ_WE_74014E
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 changes in engine speed, such as engine braking caused by up-
shifting or down-shifting, may 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 Multidrive: Be careful not to shift the shift lever with the accel-
erator pedal depressed.
This 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 P (Multidrive only) or N, the vehicle
may accelerate suddenly and unexpectedly, and may cause 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.
Vehicles with a Multidrive: 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.

When driving
iQ_WE_74014E
CAUTION
When the vehicle is parked
Do not leave glasses, cigarette lighters, spray cans, or soft drink cans in
the vehicle when it is in the sun.
Doing so may result in the following.
• Gas may leak from a cigarette lighter or spray can, and may lead to a
fire.
• The temperature inside the vehicle may cause the plastic lenses and
plastic material of eye glasses to deform or crack.
• Soft drink cans may fracture, causing the contents to spray over the
interior of the vehicle, and may also cause a short circuit in the vehi-
cle’s electrical components.
Always apply the parking brake, shift the shift lever to P (Multidrive only),
stop the engine and lock the vehicle.
Do not leave the vehicle unattended while the engine is running.
Do not touch the exhaust pipe while the engine is running or immediately
after turning the engine off.
Doing so may cause burns.
Do not leave the engine running in an area with snow build-up, or where it
is snowing. If snowbanks build up around the vehicle while the engine is
running, exhaust gases may collect and enter the vehicle. This may lead
to death or a serious health hazard.
Exhaust gases
Exhaust gases include harmful carbon monoxide (CO) that is colorless and
odorless. Inhaling exhaust gases may lead to death or a serious health haz-
ard.
If the vehicle is in a poorly ventilated area, stop the engine. In a closed
area, such as garage, exhaust gases may collect and enter the vehicle.
This may lead to death or a serious health hazard.
The exhaust 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.

If the wiper switch is turned to AUTO position while the engine switch is in
the ON position, the wiper will operate once to show that AUTO mode is
activated.
Vehicles with smart entry & start system:
If the wiper switch is turned to AUTO position while the “ENGINE START
STOP” switch is in IGNITION ON mode, the wiper will operate once to
show that AUTO mode is activated.
If the temperature of the raindrop sensor is 90°C (194°F) or higher, or
-10°C (14°F) or lower, automatic operation may not occur. In this case,
operate the wipers in any mode other than “AUTO”.
If no windshield washer fluid sprays
Check that the washer nozzles are not blocked and that there is washer fluid
in the windshield washer fluid reservoir.
CAUTION
Caution regarding the use of windshield wipers in AUTO mode
(vehicles with rain-sensing windshield wipers)
The windshield wipers may operate unexpectedly if the sensor is touched or
the windshield is subject to vibration in AUTO mode. Take care that your fin-
gers or anything else does not become caught in the windshield wipers.
NOTICE
When the windshield is dry
Do not use the wipers, as they may damage the windshield.
When there is no washer fluid spray from the nozzle
Damage to the washer fluid pump may be caused if the lever is pulled
toward you and held continually.
When a nozzle becomes blocked
Do not try to clear it with a pin or other object. The nozzle will be damaged.
