CAUTION
■Using the tire jack
Improper use of the tire jack may cause the vehicle to suddenly fall off the jack,
leading to death or serious injury.
●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 put any part of your body under th e vehicle while it is supported by the
jack.
●Do not start or run the hybrid system while your vehicle is supported by the jack.
●Do not raise the vehicle while someone is inside.
●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.
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:
●Do not touch the disc wheels or the area around the brakes immediately after the
vehicle has been driven.
After the vehicle has been driven the disc wheels and the area around the brakes
will be extremely hot. Touching these areas with hands, feet or other body parts
while changing a tire, etc. may result in burns.
●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 a serious accident. Remove any oil or
grease from the wheel bolts or wheel nuts.

If the vehicle becomes stuck
■When changing the shift position
Depress the brake pedal and ensure that t
he vehicle has stopped completely
before changing the shift position. Failure to do so could cause the rejection func -
tion to be activated, canceling the shift position change, or causing the shift position
to change to N automatically.
CAUTION
■When attempting to free a stuck vehicle
If you choose to rock the vehicle back and forth to free it, make sure the surround-
ing area is clear to avoid striking other vehicles, objects or people. The vehicle may
also lunge forward or lunge back sudden ly as it becomes free. Use extreme cau-
tion.
■When shifting the shift lever
Be careful not to shift the shift lever with the accelerator pedal depressed. 
This may lead to unexpected rapid acceleration of the vehicle that may cause an
accident resulting in death or serious injury.
Carry out the following procedures if the tires spin or the vehicle becomes
stuck in mud, dirt or snow:
Apply the parking brak e, change the shift position to P and
stop the hybrid system.
Remove the mud, snow or sand from around the stuck tire.
Place wood, stones or some othe r material under the tir
es to
help provide traction.
Restart the hybrid system.
Make sure to change the shift position to D or R, r
elease the
parking brake, and then care fully depr
ess the accelerator
pedal.
Turn off the TRAC and VSC systems if these functions are hamper -
ing your attempts to free the vehicle. (  P. 2 2 6 )
