CAUTION
■When raising your vehicle
Make sure to observe the following precautions to reduce the possibility of
death or serious injury:
●When using a floor jack, follow the instructions of the manual provided with
the jack.
● Do not use the jack that was supplied with your vehicle.
● Do not put any part of your body underneath the vehicle when it is sup-
ported only by the floor jack.
● Always use floor jack and/or automotive jack stands on a solid, flat, level
surface.
● Do not start the hybrid system while the vehicle is supported by the floor
jack.
● Stop the vehicle on level, firm ground, set the parking brake and shift the
shift lever to P.
● Make sure to set the floor jack properly at the jack point.
Raising the vehicle with an improperly positioned floor jack will damage
the vehicle and may cause the vehicle to fall off the floor jack.
● Do not raise the vehicle while someone is in the vehicle.
● When raising the vehicle, do not place any objects on top of or underneath
the floor jack.
●Lift up the vehicle using a floor jack
such as the one shown in the illustra-

■
Stopping the hybrid system
Shift the shift lever to P and press the “POWER” switch as you normally do
when stopping the hybrid system.
■ Replacing the key battery
As the above procedure is a temporary measure, it is recommended that the
electronic key battery be replaced immediately when the battery is depleted.
(P. 458)
■ Changing “POWER” switch modes
Release the brake pedal and press the “POWER” switch in above.
The hybrid system does not start and modes will be changed each time the
switch is pressed. ( P. 159)
■ If the doors cannot be locked or unlocked by the smart key system
Lock and unlock the doors by the mechanical key or wireless remote contr\
ol.
■ When the electronic key does not work properly
●Make sure that the smart key system has not been deactivated in the
customization setting. If it is off, turn the function on.
(Customizable features P. 576)
● Check if battery-saving mode is set. If it is set, cancel the function.

546 5-2. Steps to take in an emergency
CAUTION
■To prevent an accident or injury when inspecting under the hood of
your vehicle
● If steam is seen coming from under the hood, do not open the hood until
the steam has subsided. The engine compartment may be very hot, caus-
ing serious injuries such as burns.
● After the hybrid system has been turned off, check that on the
multi-information display and the “READY” indicator are off. When the
hybrid system is operating, the gasoline engine may automatically start, or
the cooling fans may suddenly operate even if the gasoline engine stops.
Do not touch or approach rotating parts such as the fans, which may lead
to fingers or clothing (especially a tie, a scarf or a muffler) getting caught,
resulting in serious injury.
● Do not loosen the coolant reservoir cap while the hybrid system and radia-
tor are hot.
Serious injuries, such as burns, may result from hot coolant and steam
released under pressure.
NOTICE
■When adding engine/power control unit coolant
Wait until the hybrid system has cooled down before adding engine/power
control unit coolant.
When adding coolant, do so slowly. Adding cool coolant to a hot hybrid sys-
tem too quickly can cause damage to the hybrid system.
■ To prevent damage to the cooling system
Observe the following precautions:
●Avoid contaminating the coolant with foreign matter (such as sand or dust
etc.)
● Do not use any coolant additive.

If the vehicle becomes stuck
CAUTION
■When attempting to free a stuck vehicle
If you choose to push the vehicle back and forth to free it, make sure the sur-
rounding area is clear to avoid striki ng other vehicles, objects or people. The
vehicle may also lunge forward or lunge back suddenly as it becomes free.
Use extreme caution.
■ 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.
NOTICE
■To avoid damage to the transmission and other components
●Avoid spinning the wheels and depressing the accelerator pedal more
than necessary.
● If the vehicle remains stuck even after these procedures are performed,
the vehicle may require towing to be freed.
Carry out the following procedures if the tires spin or the vehicle
becomes stuck in mud, dirt or snow:
Stop the hybrid system. Set the parking brake and shift the
shift lever to P.
Remove the mud, snow or sand from around the stuck tire.
Place wood, stones or some other material under the tires
to help provide traction.
Restart the hybrid system.
Shift the shift lever to the D or R position and carefully apply
the accelerator to free the vehicle.
Turn off TRAC if this function is hampering your attempts to free
the vehicle. ( P. 208)
