Electronic Key battery-Saving Function
When battery-saving mode is set, battery depletion is minimized by stopping the elec-
tronic key from re ceiving radio waves.
■
Conditions affe cting operation
The smart access system with push-button start, wireless remote control and engine
immobilizer system use weak radio waves. In the following situations, the communication
between the electronic key and the vehicle ma y be affected, preventing the smart access
system with push-button star t, wireless remote control and engine immobilizer system
from operating properly. (Ways of coping:  P. 684)●
When the electronic key battery is depleted ●
Near a TV tower, electric power plant, gas st ation, radio station, la rge display, airport or
other facility that generates strong radio wave s or electrical noise●
When the electronic key is in contact wi th, or is covered by the following metallic
objects
• Cards to which aluminum foil is attached
• Cigarette boxes that have aluminum foil inside
• Metallic wallets or bags
•Coins
• Hand warmers made of metal
• Media such as CDs and DVDs ●
When other wireless keys (that emit radio waves) are being used nearby ●
When carrying the electronic key together with the following devices that emit radio
waves
• Portable radio, cellular phone, cordle ss phone or other wireless communication
devices
• Another vehicle’s electronic key, another electronic key of your vehicle, or a wireless
key that emits radio waves
• Personal computers or person al digital assistants (PDAs)
• Digital audio players
• Portable game systems ●
If window tint with a metallic content or me tallic objects are atta ched to the rear win-
dow ●
When the electronic key is placed near a battery charger or electronic devices ●
When the vehicle is parked in a pay parking spot where radio waves are emittedPress twice while pressing and holding .
Confirm that the electronic key indicator flashes
4 times.
While the battery-saving mode is set, the smart
access system with push -button start cannot be

When starting off on a uphill
The hill-start assist control will activate. (  P. 378)■
Driving in the rain ●
Drive carefully when it is ra ining, because visibility will be reduced, the windows may
become fogged-up, and the road will be slippery. ●
Drive carefully when it starts to rain, beca use the road surface will be especially slip-
pery. ●
Refrain from high speeds when driving on an expressway in the rain, because there may
be a layer of water between the tires and th e road surface, preventing the steering and
brakes from operating properly. ■
Engine speed while driving
In the following conditions, th e engine speed may become high while driving. This is due
to automatic up-shifting control or down-shi fting implementation to meet driving condi-
tions. It does not indica te sudden acceleration.●
The vehicle is judged to be driving uphill or downhill ●
When the accelerato r pedal is released●
When the brake pedal is depressed while sport mode is selected ■
Restraining the engine output (Brake Override System)●
When the accelerator and brake pedals are depressed at the same time, the engine
output may be restrained. ●
A warning message is displayed on the mult i-information display while the system is
operating. If a warning messa ge is shown on the multi-in formation display, read the
message and follow the instructions. ■
Restraining sudden start (Drive-Start Control)●
When the following unusual operation is performed, the engine output may be
restrained.
• When the shift lever is shifted from R to D, D to R, N to R, P to D, or P to R (D
includes M or S) with the accelerator pedal depressed, a warning message appears
on the multi-information display. If a wa rning message is shown on the multi-infor-
mation display, read the messa ge and follow the instructions.
• When the accelerator pedal is depressed t oo much while the vehicle is in reverse.●

208 4-1. Before driving
RX350/RX350L_U WARNING
Observe the following precautions.
Failure to do so may result in death or serious injury. ■
When taking a nap in the vehicle
Always turn the engine off. Otherwise, if you accidentally move the shift lever or
depress the accelerator pedal, this could cause an accident or fire due to engine over-
heating. Additionally, if the ve hicle is parked in a poorly ventilated area, exhaust gases
may collect and enter the vehicle, leading to death or a serious health hazard. ■
When braking ●
When the brakes are wet, drive more cautiously.
Braking distance increases when the brakes are wet, and this may cause one side of
the vehicle to brake differently than the other side. Also, the parking brake may not
securely hold the vehicle. ●
If the brake booster device does not operate, do not follow other vehicles closely and
avoid hills or sharp turns that require braking.
In this case, braking is still possible, bu t the brake pedal should be depressed more
firmly than usual. Also, the braking distan ce will increase. Have your brakes fixed
immediately. ●
Do not pump the brake pedal if the engine stalls.
Each push on the brake pedal uses up the reserve for the power-assisted brakes. ●
The brake system consists of 2 individual hy draulic systems; if one of the systems fails,
the other will still operate. In this case, the brake pedal should be depressed more
firmly than usual and the bra king distance will increase.
Have your brakes fixed immediately. ■
If the vehicle becomes stuck (AWD models)
Do not spin the wheels excessive ly when any of the tires is up in the air, or the vehicle is
stuck in sand, mud, etc. This may damage the driveline components or propel the vehi-
cle forward or backward, causing an accident.
