CAUTION
The engine compartment contains many mechanisms and fluids that may
move suddenly, become hot, or become electrically energized. To avoid death
or serious injury, observe the following precautions.
When working on the engine compartment
Keep hands, clothing, and tools away from the moving fan and engine
drive belt.
Be careful not to touch the engine, radiator, exhaust manifold, etc. right
after driving as they may be hot. Oil and other fluids may also be hot.
Do not leave anything that may burn easily, such as paper or rags, in the
engine compartment.
Do not smoke, cause sparks or expose an open flame to fuel or the bat-
tery. Fuel and battery fumes are flammable.
Be extremely cautious when working on the battery. It contains poisonous
and corrosive sulfuric acid.
Take care because brake fluid can harm your hands or eyes and damage
painted surfaces.
If fluid gets on your hands or in your eyes, flush the affected area with
clean water immediately.
If you still experience discomfort, see a doctor.
When working near the electric cooling fan or radiator grille
Vehicles without smart entry & start system:
Be sure the engine switch is in the LOCK position.
With the engine switch in the ON position, the electric cooling fan may
automatically start to run if the air conditioning system is on and/or the
coolant temperature is high. (P. 342)
Vehicles with smart entry & start system:
Be sure the “ENGINE START STOP” switch is in the OFF.
With the “ENGINE START STOP” switch in the IGNITION ON mode, the
electric cooling fan may automatically start to run if the air conditioning
system is on and/or the coolant temperature is high. (P. 342)
Safety glasses
Wear safety glasses to prevent flying or falling material, fluid spray, etc. from
getting in the eyes.

CAUTION
When raising your vehicle
Make sure to observe the following to reduce the possibility of death or seri-
ous injury.
When using a floor jack, follow the instructions of the manual provided with
the jack.
Do not use the jack that was supplied with your vehicle.
Do not put any part of your body or get underneath the vehicle supported
only by the floor jack.
Always use floor jack and/or automotive jack stands on a solid, flat, level
surface.
Do not start the engine while the vehicle is supported by the floor jack.
Stop the vehicle on level firm ground, firmly set the parking brake and put
the shift lever in P (Multidrive) or R (manual transmission).
Make sure to set the floor jack properly at the jack point.
Raising the vehicle with an improperly positioned floor jack will damage
the vehicle and may cause the vehicle to fall off the floor jack.
Do not raise the vehicle while someone is in the vehicle.
Lift up the vehicle using a floor jack
such as the one shown in the illustra-
tion.
Do not jack the vehicle at sections such
as the rear suspension. The vehicle
may be damaged.

Emergency towing
If a tow truck is not available, in an emergency your vehicle may be
temporarily towed using a cable or chain secured to the emergency
towing eyelet. This should only be attempted on hard, surfaced roads
for short distances at low speeds.
A driver must be in the vehicle to steer and operate the brakes. The
vehicle’s wheels, drive train, axles, steering and brakes must be in
good condition.
Towing eyelet
Emergency towing procedure
Start the engine.
Vehicles without smart entry & start system:
If the engine cannot be started, turn the engine switch to the ACC
or ON position.
Vehicles with smart entry & start system:
If the engine cannot be started, press the “ENGINE START STOP”
switch to change to the ACCESSORY or IGNITION ON mode.
Put the shift lever in N.
Release the parking brake.

iQ_WE_74014E
Installing towing eyelet
Remove the eyelet cover using a
flathead screwdriver.
To protect the bodywork, place a
rag between the screwdriver and
the vehicle body, as shown in the
illustration.
CAUTION
Caution while towing
Use extreme caution when towing the vehicle.
Avoid sudden starts or erratic driving maneuvers which place excessive
stress on the emergency towing eyelet and the cables or chains. Always
be cautious of the surroundings and other vehicles while towing.
If the engine is not running, the power assist for the brakes and steering
will not function, making steering and braking more difficult.
NOTICE
To prevent serious damage to the transmission
(vehicles with a Multidrive)
Never tow this vehicle from the rear with the front wheels on the ground.
This may cause serious damage to the transmission.
When towing a vehicle without using a towing dolly
(vehicles with a manual transmission)
Vehicles without smart entry & start system:
Do not tow the vehicle with the key removed or in the LOCK position.
Vehicles with smart entry & start system:
Do not tow the vehicle with the “ENGINE START STOP” switch OFF.

Towing with a wheel lift-type truck from the rear
Vehicles with a Multidrive: Use a
towing dolly under the front
wheels.
Vehicles with a manual transmis-
sion: We recommend the use of
a towing dolly under the front
wheels.
Vehicles without smart entry &
start system: When not using a
towing dolly, turn the engine
switch to the ACC position and
shift the shift lever to N.
Vehicles with smart entry & start
system: When not using a towing
dolly, turn the “ENGINE START
STOP” switch to the ACCES-
SORY or IGNITION ON mode
and shift the shift lever to N.
NOTICE
To prevent serious damage to the transmission

iQ_WE_74014E
Using a flat bed truck
If your Toyota is transported by a
flat bed truck, it should be tied
down at the locations shown in
the illustration.
If you use chains or cables to tie
down your vehicle, the angles
indicated by triangles must be
45.
Do not overly tighten the tie
downs or the vehicle may be
damaged.
Apply the parking brake firmly.
NOTICE
To prevent damage to the vehicle
(vehicles with a manual transmission)
Vehicles without smart entry & start system: Do not tow the vehicle from
the rear with the key removed or in the LOCK position. The steering lock
mechanism is not strong enough to hold the front wheel straight.
Vehicles with smart entry & start system: Do not tow the vehicle from the
rear with the “ENGINE START STOP” switch OFF. The steering lock
mechanism is not strong enough to hold the front wheel straight.
When raising the vehicle, ensure adequate ground clearance for towing at
the opposite end of the raised vehicle. Without adequate clearance, the
vehicle could be damaged while being towed.
