resents the engine speed range which exceeds the maximum safe engine speed.
●In the following situations, the engine
may be overheating. In this case, immediately stop the vehicle in a safe place, and check the engine after it has
cooled completely. ( P.400, 403)
• The engine coolant temperature gauge is in the red zone (H).

Displays the average vehicle speed since
the function was reset and the engine
<hybrid system> was started, respectively
 Elapsed time (after reset*2/after
start)*1
Displays the elapsed time since the func-

tem> was started, respectively
 Distance (range/after start)*1
Displays the estimated maximum distance
that can be driven with the quantity of fuel
remaining and the distance driven after the

respectively.
• This distance is computed based on your
average fuel consumption. As a result,
the actual distance that can be driven
may differ from that displayed.
• When only a small amount of fuel is

■Battery-saving function
The battery-saving function will be acti-
vated in order to prevent the electronic key battery and the 12-volt battery from being discharged while the vehicle is not in opera-
tion for a long time.
●In the following situations, the smart entry
& start system may take some time to unlock the doors.• The electronic key has been left within
approximately 2 m (6 ft.) of the outside of the vehicle for 10 minutes or longer.• The smart entry & start system has not
been used for 5 days or longer.
●If the smart entry & start system has not
been used for 14 days or longer, the doors cannot be unlocked at the passen-ger door. In this case, push the depres-
sion on the front edge of the driver’s door handle, or use the wireless remote con-trol or mechanical key, to unlock the
doors.
■Turning an electronic key to battery- saving mode
When battery-saving mode is set, battery depletion is minimized by stopping the elec-
tronic key from receiving radio waves.
Press twice while pressing and
holding . Confirm that the elec-
tronic key indicator flashes 4 times.
While the battery-saving mode is set, the smart entry & start system cannot be used. To cancel the function, press any of the elec-
tronic key buttons.
■Conditions affecting operation
The smart entry & star t system uses weak radio waves. In the following situations, the
communication between the electronic key and the vehicle may be affected, preventing
the smart entry & start system, wireless remote control and engine immobilizer sys-tem <immobilizer syst em> from operating
properly. (Ways of coping: P.389)
●When the electronic key battery is
depleted
●Near a TV tower, electric power plant,
gas station, radio station, large display, airport or other facility that generates strong radio waves or electrical noise
●When carrying a portable radio, cellular phone, cordless phone or other wireless
communication device
●When the electronic key is in contact
with, or is covered by the following metal- lic 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• Another vehicle’s electronic key or a
wireless key that emits radio waves • Personal computers or personal digital assistants (PDAs)
• Digital audio players • Portable game systems
●If window tint with a metallic content or metallic objects are attached to the rear window
●When the electronic key is placed near a battery charger or electronic devices
■Note for the entry function
●Even when the electronic key is within the effective range (detection areas), the sys-
tem may not operate properly in the fol- lowing cases:• The electronic key is too close to the win-
dow or outside door handle, near the ground, or in a high place when the doors are locked or unlocked.

In the event that you drive on a flooded road and the vehicle is flooded, be sure
to have any authorized Lexus retailer or Lexus authorized repairer, or any reliable repairer check the following:
●Brake function
●Changes in quantity and quality of oil
and fluid used for the engine, transmis- sion, differentials, etc.
●Lubricant condition for the propeller shaft, bearings and suspension joints
(where possible), and the function of all joints, bearings, etc.
If the shift control system is damaged by flooding, it may not be possible to shift
the shift position to P, or from P to other positions. In this case, contact any autho-rized Lexus retailer or Lexus authorized
repairer, or any reliable repairer immedi- ately.
■When parking the vehicle
Always set the parking brake, and shift the shift position to P. Failure to do so may cause the vehicle to move or the

•Washer fluid
 Have a service technician inspect
the condition of the 12-volt battery.
 Have the vehicle fitted with four
snow tires.
Ensure that all tires are the specified size
and the same brand.
 Tire chains can only be installed on
the rear tires. However, tire chains
cannot be installed on 275/35RF21
