Maintenance and care
iQ_WE_74014ERaise the vehicle until the tire is
slightly raised off the ground.
Remove all the wheel nuts and
the tire.
When resting the tire on the
ground, place the tire so that the
wheel design faces up to avoid
scratching the wheel surface.
Installing the tire
Remove any dirt or foreign mat-
ter from the wheel contact sur-
face.
If foreign matter is on the wheel
contact surface, the wheel nuts
may loosen while the vehicle is in
motion, and the tire may come off
the vehicle.

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.

Maintenance and care
iQ_WE_74014E
CAUTION
When installing the wheel nuts
Never use oil or grease on the wheel bolts or wheel nuts.
Oil and grease may cause the wheel nuts to be excessively tightened,
leading to bolt or disc wheel damage. In addition, the oil or grease can
cause the wheel nuts to loosen and the wheel may fall off, causing an acci-
dent and resulting in death or serious injury. Remove any oil or grease
from the wheel bolts or wheel nuts.
Be sure to install the wheel nuts with
the tapered end facing inward. Install-
ing the nuts with the tapered end facing
outward can cause wheel to break and
eventually cause a wheel to come off
while driving, which could lead to an
accident resulting in death or serious
injury.Tapered
