■Conditions which may affect the rear view monitor system
●If the back of the vehicle is hit, the camera’s position and mounting angle may
change. See your Lexus dealer.
●Rapid temperature changes, such as when hot water is poured on the vehicle in
cold weather, may cause the system to function abnormally.
●If the camera lens is dirty, it cannot transmit a clear image. Rinse with water and
wipe with a soft cloth. If extremely dirty, wash with a mild cleanser and rinse.

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. 
Observe the following precautions to prevent accidents.
• 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 this tire jack on other vehicl
es, and do not 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.
• 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.
• 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 may be injured.
■Replacing a flat tire
Observe the following precautions to reduce
the risk of death or serious 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.
R
emove any oil or grease on the wheel bolts or wheel nuts.
• Have the wheel nuts tightene d with a tor
que wrench to 76 f t•lbf (105 N•m, 10.5
kgf
•m) as soon as possible after changing wheels. 
Failure to follow these pre-cautions could cause, the wheel nuts to loosen and the
w
