CAUTION
Storage precautions
Never allow anyone to ride in the luggage compartment. It is not designed
for passengers. They should ride in their seats with their seat belts prop-
erly fastened. Otherwise, they are much more likely to suffer death or seri-
ous bodily injury, in the event of sudden braking, sudden swerving or an
accident.
Secure all items in the occupant compartment, as they may shift and injure
someone during sudden braking, sudden swerving or an accident.

CAUTION
Observe the following precautions.
Failure to do so may cause the driver’s floor mat to slip, possibly interfering
with the pedals while driving. An unexpectedly high speed may result or it may
become difficult to stop the vehicle, leading to a serious accident.
When installing the driver’s floor mat
Do not use floor mats designed for other models or different model year
vehicles, even if they are Toyota Genuine floor mats.
Only use floor mats designed for the driver’s seat.
Always install the floor mat securely using the retaining hooks (clips) pro-
vided.
Do not use two or more floor mats on top of each other.
Do not place the floor mat bottom-side up or upside-down.
Before driving
Check that the floor mat is securely
fixed in the correct place with all the
provided retaining hooks (clips). Be
especially careful to perform this check
after cleaning the floor.
With the engine stopped and the shift
lever in P (Multidrive) or N (manual
transmission), fully depress each pedal
to the floor to make sure it does not
interfere with the floor mat.

iQ_WE_74014E
CAUTION
Using the jack
Improper use of the jack may lead to death or serious injuries due to the
vehicle suddenly falling off the jack.
Do not use the jack for any purpose other than replacing tires or installing
and removing tire chains.
Only use the jack that comes with this vehicle for replacing a tire.
Do not use it on other vehicles, and do not use other jacks for replacing
tires on this vehicle.
Always check that the jack is securely set to the jack point.
Do not put any part of your body under the vehicle supported by a jack.
Do not start or run the engine while your vehicle is supported by the jack.
Do not raise the vehicle while someone is in it.
When raising the vehicle, do not put an object on or under the jack.
Do not raise the vehicle to a height greater than that required to replace
the tire.
Use a jack stand if it is necessary to get under the vehicle.
Take particular care when lowering the vehicle to ensure that no one working
on or near the vehicle will be injured.
Replacing a tire
Observe the following precautions to reduce the risk of death or serious
injury.
Have the wheel nuts tightened with a torque wrench to 103 N·m (10.5
kgf·m, 76 ft·lbf) as soon as possible after changing wheels.
Failure to follow these precautions could cause the nuts to loosen and the
wheel may fall off, which could lead to an accident causing death or seri-
ous injury.
Do not attach a heavily damaged wheel ornament, as it may fly off the
wheel while the vehicle is moving.
