5-2. Steps to take in an emergency
CAUTION
■Replacing a flat tire
Observe the following precautions to reduce the risk of injury.
●Lower the spare tire completely to the ground before removing it from under the
vehicle.
●Do not try to remove the wheel ornament by hand. Take due care in handling the
ornament to avoid unexpected personal injury.
●Never use oil or grease on the wheel bolts or wheel nuts.
The oil or grease can cause the wheel nuts to loosen, causing a serious accident.
Remove any oil or grease on the wheel bolts or wheel nuts.
●Have the wheel nuts tightened with a torque wrench to 83 ft•lbf (112 N•m, 11.5
kgf•m) as soon as possible after changing wheels.
Failure to follow these precautions could cause the nuts to loosen and the wheels
may fall off, which could lead to an accident causing death or serious injury.
●Do not attach a heavily damaged wheel orna ment, as it may fly off the wheel while
the vehicle is moving.

Lubrication system
*: 5W-30 is an oil that provides optimal levels of fuel efficiency.
Oil viscosity:
● The 5W portion of the oil viscosity rating indicates the characteristic of
the oil which allows cold startability . Oils with a lower value before the W
allow for easier starting of the engine in cold weather.
● The 30 in 5W-30 indicates the oil viscosity when the oil is as its operating
temperature. An oil with a higher viscosity may be better suited if the
vehicle is operated at high speeds, or under extreme load conditions.
