WARNING
Observe the following precautions. Failure to do so may result in death or serious injury.
■When the vehicle is stopped
●Do not depress the accelerator pedal unnecessarily.If the shift lever is in any position other than P or N, the vehicle may accelerate sud-denly and unexpectedly, causing an accident.
●In order to prevent accidents due to the vehicle rolling away, always keep depressingthe brake pedal while stopped with the “READY” indicator is illuminated, and applythe parking brake as necessary.
●If the vehicle is stopped on an incline, in order to prevent accidents caused by thevehicle rolling forward or backward, alwa ys depress the brake pedal and securely apply the parking brake as needed.
●Avoid revving or racing the engine. Running the engine at high speed while the vehicle is stopped may cause the exhaustsystem to overheat, which could result in a fire if combustible material is nearby.
■When the vehicle is parked
●Do not leave glasses, cigarette lighters, spray cans, or soft drink cans in the vehicle when it is in the sun.
Doing so may result in the following:
• Gas may leak from a cigarette lighter or spray can, and may lead to a fire. • The temperature inside the vehicle may cau se the plastic lenses and plastic mate-
rial of glasses to deform or crack. • Soft drink cans may fracture, causing the contents to spray over the interior of thevehicle, and may also cause a short circuit in the vehicle’s electrical components.
●Do not leave cigarette lighters in the vehicle. If a cigarette lighter is in a place such as the glove box or on the floor, it may be lit accidentally when luggage is loaded or the
seat is adjusted, causing a fire.
●Do not attach adhesive discs to the windshield or windows. Do not place containers such as air fresheners on the instrument panel or dashboard. Adhesive discs or con-
tainers may act as lenses, causing a fire in the vehicle.
●Do not leave a door or window open if the curved glass is coated with a metallized film such as a silver-colored one. Reflected sunlight may cause the glass to act as a
lens, causing a fire.
●Always apply the parking brake, shift the shift lever to P, stop the hybrid system and lock the vehicle.
Do not leave the vehicle unattended while the “READY” indicator is illuminated. If the vehicle is parked with the shift lever in P but the parking brake is not set, thevehicle may start to move, possibly leading to an accident.
●Do not touch the exhaust pipes while the “READY” indicator is illuminated or imme-diately after turning the hybrid system off.Doing so may cause burns.

■Automatic deactivation of shift range selection in the D position
Shift range selection in the D position will be deactivated in the following situations:
●When the vehicle comes to a stop
●If the accelerator pedal is depressed for more than a certain period of time
●When the shift lever is shifted to a position other than D
■Downshifting restriction warning buzzer
To help ensure safety and driving performa nce, downshifting operation may sometimes
be restricted. In some circumstances, down shifting may not be possible even when the shift lever or paddle shift switch is operated. (A buzzer will sound twice.)
■Snow mode automatic deactivation
Snow mode is automatically deactivated if the power switch is turned off after driving in snow mode.
■When driving with cruise control or dynamic radar cruise control activated
Even when performing the following actions with the intent of enabling engine braking, engine braking will not activate because crui se control or dynamic radar cruise control will not be canceled.
●While driving in the D or S position, downshifting to 5 or 4. ( P. 253, 257)
●When switching the driving mode to sport mode while driving in D position. (P. 301)
■Shift lock system
The shift lock system is a system to prevent accidental operation of the shift lever in start- ing.

WARNING
■When driving on slippery road surfaces
Be careful of downshifting and sudden acceler ation, as this could result in the vehicle skidding to the side or spinning.
■To prevent an accident wh en releasing the shift lock
Before pressing the shift lock override butt on, make sure to set the parking brake and depress the brake pedal.
If the accelerator pedal is accidentally depressed instead of the brake pedal when the shift lock override button is pressed and the shift lever is shifted out of P, the vehicle may suddenly start, possibly leading to an accident resulting in death or serious injury.
