(Flashing)
The transmission is out of
“P” when attempting to
start the hybrid system.Shift the shift lever to “P”
before pressing the power
switch.
■After changing the engine oil (U.S.A. only)
Make sure to reset the oil maintenance data. (P. 3 74 )
■Approach warning message
In the following instances, there is the poss ibility that the approach warning will not
activate even when the vehicle-to-vehicle distance decreases.
●When your vehicle and the vehicle ahead are traveling at the same speed or the

5-2. Steps to take in an emergency
CAUTION
■Using the tire jack
Improper use of the tire jack may lead to death or injuries due to the vehicle sud-
denly falling off the jack.
●Do not use the tire jack for any purpose other than replacing tires or installing and
removing tire chains.
●Only use the tire jack that comes with this vehicle for replacing a flat tire. 
Do not use it on other vehicles, and do no t use other tire jacks for replacing tires
on this vehicle.
●Always check that the tire jack is securely set to the jack point.
●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 greate r than that required to replace the tire.
●Use a jack stand if it is necessary to get under the vehicle.
●Do not put any part of your body under the vehicle supported by a jack.
●Do not start or run the hybrid system while your vehicle is supported by the jack.
Take particular care when lowering the vehicle to ensure that no one working on or
near the vehicle may be injured.
■Replacing a flat tire
Observe the following precautions to reduce the risk of 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 76 ft•lbf (103 N•m, 10.5
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.

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 condition.
