Electronic Key battery-Saving Function
When battery-saving mode is set, battery depletion is minimized by stopping the elec-
tronic key from receiving radio waves.
■
Conditions affe cting operation
The smart access system with push-button star t, wireless remote control and immobilizer
system use weak radio waves. In the followi ng situations, the communication between the
electronic key and the vehicle may be affected, preventing the smart access system with
push-button start, wireless remote control and immobilizer system from operating prop-
erly. (Ways of coping:  P. 5 6 4 )●
When the electronic key battery is depleted ●
Near a TV tower, electric powe r plant, gas station, radio stat ion, large display, airport or
other facility that generates strong radio waves 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, cordless phone or other wireless communication
devices
• Another vehicle’s electronic key, another el ectronic 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 attached to the rear win-
dow ●
When the electronic key is placed near a battery charger or electronic devicesPress 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
used. To cancel the function, press any of the
electronic key buttons.

To avoid malfunction of the camera sensor
Observe the following precautions.
Otherwise, the camera sensor may not operat e properly, possibly leading to an acci-
dent resulting in death or serious injury. ●
Keep the windshield clean at all times.
• If the windshield is dirty or covered with an oily film, water droplets, snow, etc.,
clear the windshield.
• If a glass coating agent is applied to the windshield, it will still be necessary to use
the windshield wipers to remove water drop lets from the area of the windshield in
front of the camera sensor.
• If the inner side of the windshield where th e camera sensor is installed is dirty, con-
tact your Lexus dealer.
●
If the part of the windshield in front of th e camera sensor is fogged up or covered with
condensation or ice, use the windshield defogger to remove the fog, condensation or
ice. (  P. 4 0 9 )●
If water droplets cannot be properly remove d from the area of the windshield in front
of the camera sensor by the windshield wipers, replace the wiper insert or wiper
blade.

390 4-6. Driving tips
RX450h_U_OM0E013U ●
Use fluids that are appropriate to the prevailing outside temperatures.
•Engine oil
• Engine/power control unit coolant
• Washer fluid ●
Have a service technician inspect the condition of the 12-volt battery. ●
Have the vehicle fitted with four snow tires or purchase a set of tire chains for
the front tires. Ensure that all tires are of the specified size and the same brand, and that chains
match the size of the tires.
Perform the following according to the driving conditions: ●
Do not try to forcibly open a window or move a wiper that is frozen. Pour
warm water over the frozen area to melt the ice. Wipe away the water imme-
diately to prevent it from freezing. ●
To ensure proper operation of the climate control system fan, remove any
snow that has accumulated on the air inlet vents in front of the windshield. ●
Check for and remove any excess ice or snow that may have accumulated on
the exterior lights, vehicle’s roof, chassis, around the tires or on the brakes. ●
Remove any snow or mud from the bottom of your shoes before getting in the
vehicle.Winter driving tips Carry out the necessary preparations and inspections before driving the vehi-
cle in winter. Always drive the vehicle in a manner appropriate to the prevail-
ing weather conditions.

Off-road driving precautions
Always observe the following precautions to minimize the risk of death, serious injury
or damage to your vehicle: ●
Drive carefully when off the road. Do not ta ke unnecessary risks by driving in danger-
ous places. ●
Do not grip the steering wheel spokes when driving off-road. A bad bump could jerk
the wheel and injure your hands. Keep both hands and especially your thumbs on the
outside of the rim. ●
Always check your brakes for effectivenes s immediately after driving in sand, mud,
water or snow. ●
After driving through tall grass, mud, rock, sand, rivers, etc., check that there is no
grass, bush, paper, rags, stone, sand, etc. adhering or trapped on the underbody.
Clear off any such matter from the underbody. If the vehicle is used with these materi-
als trapped or adhering to the underb ody, a breakdown or fire could occur.●
When driving off-road or in rugged terrai n, do not drive at excessive speeds, jump,
make sharp turns, strike objects, etc. This may cause loss of control or vehicle rollover
causing death or serious injury. You are also risking expensive damage to your vehi-
cle’s suspension and chassis.
NOTICE ■
To prevent water damage
Take all necessary safety measures to ensure that water damage to the hybrid battery
(traction battery), hybrid system or other components does not occur. ●
Water entering the engine compartment may cause severe damage to the hybrid
system. Water entering the interior may cause the hybrid battery (traction battery)
stowed under the rear seats to short circuit. ●
Water entering the hybrid transmission and rear electric motor (traction motor)
(AWD models only) will cause deterioration in transmission qua lity. The malfunction
indicator may come on, and the vehicle may not be drivable. ●
Water can wash the grease from wheel be arings, causing rusting and premature fail-
ure, and may also enter the hybrid transmission case, reducing the gear oil’s lubricat-
ing qualities. ■
When you drive through water
If driving through water, such as when crossing shallow streams, first check the depth of
the water and the bottom of the riverbed for firmness. Drive slowly and avoid deep
water. ■
Inspection after off-road driving ●
Sand and mud that has accumulated around brake discs may affect braking efficiency
and may damage brake system components. ●
Always perform a maintenance inspection after each day of off-road driving that has
taken you through rough terr ain, sand, mud, or water. For scheduled maintenance
information, refer to the “Warranty and Services Guide/Owner’s Manual Supple-
ment/Scheduled Maintenance”.
