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

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

Engine oil consumption
A certain amount of engine oil will be consumed while driving. In the follow-
ing situations, oil consumption may increase, and engine oil may need to be
refilled in between oil maintenance intervals.
When the engine is new, for example directly after purchasing the vehicle
or after replacing the engine
If low quality oil or oil of an inappropriate viscosity is used
When driving at high engine speeds or with a heavy load, or when driving
while accelerating or decelerating frequently
When leaving the engine idling for a long time, or when driving frequently
through heavy traffic
CAUTION
Used engine oil
Used engine oil contains potentially harmful contaminants which may
cause skin disorders such as inflammation or skin cancer, so care should
be taken to avoid prolonged and repeated contact. To remove used engine
oil from your skin, wash thoroughly with soap and water.
Dispose of used oil and filters only in a safe and acceptable manner. Do
not dispose of used oil and filters in household trash, in sewers or onto the
ground. Call any authorized Toyota dealer or repairer, or another duly
