iQ_WE_74014E
System maintenance
The vehicle has a maintenance-free type alarm system.
Items to check before locking the vehicle
To prevent unexpected triggering of the alarm and vehicle theft, make sure
of the following.
Nobody is in the vehicle.
The windows are closed before the alarm is set.
No valuables or other personal items are left in the vehicle.
Triggering of the alarm
The alarm may be triggered in the following situations.
(Stopping the alarm deactivates the alarm system.)
Deactivating or stopping the alarm
Do one of the following to deactivate or stop the alarm.
Unlock the doors or back door using the entry function (vehi-
cles with smart entry & start system) or wireless remote con-
trol.
Start the engine. (The alarm will be deactivated or stopped
after a few seconds.)
The doors are unlocked using the key
(vehicles without smart entry & start
system) or mechanical key (vehicles
with smart entry & start system).

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.

When driving
iQ_WE_74014E
CAUTION
When driving the vehicle
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 D (Multidrive) or 1 (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. 440)
Use engine braking 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. 185, 189)
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 position 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
that may result in death or serious injury.
Always check that all passengers’ arms, heads or other parts of their bod-
ies are not outside the vehicle, as this may result in death or serious injury.

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.
