Driving the vehicle
Starting off on a steep uphill
Make sure that the pa rking brake is set and shift the shift lever to
D.
Gently depress the accelerator pedal.
Release the parking brake. The following procedures should be observed to ensure safe driving.
■ Starting the hybrid system
 P. 177
■ Driving
With the brake pedal depressed, shift the shift lever to D.
(  P. 1 8 6 )
Release the parking brake. (  P. 195)
Gradually release the brake pedal and gently depress the
accelerator pedal to accelerate the vehicle.
■ Stopping
With the shift lever in D, depress the brake pedal.
If necessary, set the parking brake. If the vehicle is to be stopped for an extended period of time, shift the
shift lever to P. (
 P. 1 8 6 )
■

When driving ■
When starting off on an uphill
The hill-start assist control is available. (  P. 2 76 )■
Driving in the rain ●
Drive carefully when it is raining, becaus e visibility will be reduced, the windows
may become fogged-up, and the road will be slippery.●
Drive carefully when it starts to rain, be cause the road surface will be especially
slippery.●
Refrain from high speeds when driving on an expressway in the rain, because
there may be a layer of water between th e tires and the road surface, preventing
the steering and brakes from operating properly.■
Engine speed while driving
In the following conditions, the engine speed may become high while driving. This is
due to automatic up-shifting control or down-shifting implementation to meet driv-
ing conditions. It does not indicate sudden acceleration.●
The vehicle is judged to be driving uphill or downhill●
When the accelerator pedal is released●
When the brake pedal is depresse d while sport mode is selected■
Breaking in your new Lexus
To extend the life of the vehicle, observing the following precautions is recom-
mended: ●
For the first 200 miles (300 km):
Avoid sudden stops.●
For the first 500 miles (800 km):
Do not tow a trailer.●
For the first 1000 miles (1600 km):
• Do not drive at extremely high speeds.
• Avoid sudden acceleration.
• Do not drive continuously in low gears.
• Do not drive at a constant speed for extended periods.

1682-1. Driving procedures
■
Drum-in-disc type parking brake system
Your vehicle has a drum-in-disc type parking brake system. This type of brake sys-
tem needs bedding-down of the brake shoe s periodically or whenever the parking
brake shoes and/or drum are replaced. Have your Lexus dealer perform the bed-
ding down operation.■
Operating your vehicle in a foreign country
Comply with the relevant vehicle registration laws and confirm the availability of the
correct fuel. (  P. 800)■
For efficient use ●
Shift the shift lever to D when driving.
In the N position, the gasoline engine op erates but electricity cannot be gener-
ated. The hybrid battery (traction battery) will discharge, requiring unnecessary
engine power to recharge.●
Drive your vehicle smoothly.
Avoid abrupt acceleration and deceleration. Gradual acceleration and decel-
eration will make more effective use of the electric motor (t raction motor) with-
out having to use gasoline engine power.●
Avoid repeated acceleration.
Repeated acceleration consumes hybrid battery (traction battery) power,
resulting in poor acceleration. Battery power can be restored by driving with
the accelerator pedal slightly released.●
Shift the shift lever to P when parking.
In the N position, the hybrid battery (traction battery) does not recharge.
Leaving the shift lever in the N position for an extended period of time may dis-
charge the hybrid battery. The vehicle cannot run if the hybrid battery is dis-
charged.■
Eco-friendly driving
 P. 1 9 9
CAUTION
■
When starting the vehicle
Always keep your foot on the brake pe dal while stopped with the hybrid system
operating. This prevents the vehicle from creeping.

When driving Power (ignition) switch Performing the following operations when carrying the electronic key on
your person starts the hybrid system or changes “POWER” switch modes.
■ Starting the hybrid system
Check that the parking brake is set.
Check that the shift lever is set in P.
Firmly depress the brake pedal. The “POWER” switch indicator will turn green. If the indicator does
not turn green, the hybrid system cannot be started.
Press the “POWER” switch. After a while, the “READY” indi-
cator comes on with a beep
sound.
The vehicle can move when the
“READY” indicator is on even if
the engine is stopped.
Continue depressing the brake
pedal until the hybrid system is
completely started.
The hybrid system can be
started from any “POWER”
switch mode.
Check that the “READY” indicator is on.
The vehicle will not move when the “READY” indicator is off.STEP 1

When driving When stopping the hybrid system with the shift lever in a position other than P
If the hybrid system is stopped with the shift lever in a position other than
P, the “POWER” switch will not be turned off but instead be turned to
ACCESSORY mode. Perform the following procedure to turn the switch
off:
Check that the parking brake is set.
Shift the shift lever to P.
Check that the indicator on the “POWER” switch is illuminated in
amber and then press the “POWER” switch once.
Check that the indicator on the “POWER” switch is off.■
Auto power off function
When the shift lever is in P, if the vehicle is left in ACCESSORY or ON mode with
the hybrid system not operating for more than 20 minutes (ACCESSORY mode)
or one hour (ON mode), the “POWER” switch will automatically turn off. However,
this function cannot entirely prevent 12-v olt battery discharge. Do not leave the
vehicle with the “POWER” switch in ACCESSORY or ON mode for long periods
of time when the hybrid system is not operating.■
Operation of the “POWER” switch
When operating the “POWER” switch, one short, firm press is enough. If the switch
is pressed improperly, the hybrid system may not start or the “POWER” switch
mode may not change. It is not necessary to press and hold the switch.■

When driving CAUTION■
When starting the hybrid system
Always start the hybrid system while sitting in the driver’s seat. Do not depress the
accelerator pedal while starting the hybrid system under any circumstances.
Doing so may cause an accident resu lting in death or serious injury.■
Caution while driving
If a hybrid system failure occurs while the vehicle is moving, do not lock or open the
doors until the vehicle reaches a safe and complete stop. Activation of the steering
lock in this circumstance may lead to an accident, resulting in death or serious
injury.■
Stopping the hybrid system in an emergency
If you want to stop the hybrid system in an emergency while driving the vehicle,
press and hold the “POWER” switch for more than 2 seconds, or press it briefly 3
times or more in succession. (  P. 795)
However, do not touch the “POWER” switch while driving except in an emergency.
Turning the hybrid system off while driving wi ll not cause loss of steering or braking
control, however, power assist to the steering will be lost. This will make it more diffi-
cult to steer smoothly, so you should pull over and stop the vehicle as soon as it is
safe to do so.

1822-1. Driving procedures
NOTICE■
To prevent 12-volt battery discharge ●
Do not leave the “POWER” switch in ACCESSORY or ON mode for long peri-
ods of time without the hybrid system on.●
If the indicator on the “POWER” switch is illuminated, the “POWER” switch is not
off. When exiting the vehicle, always check that the “POWER” switch is off.●
Do not stop the hybrid system when the shif t lever is in a position other than P. If
the hybrid system is stopped in anothe r shift lever position, the “POWER” switch
will not be turned off but instead be tu rned to ACCESSORY mode. If the vehicle
is left in ACCESSORY mode, 12-volt battery discharge may occur.■
When starting the hybrid system ●
Do not depress the accelerator pedal unnecessarily.●
If the hybrid system becomes difficult to start, have your vehicle checked by your
Lexus dealer immediately.■
Symptoms indicating a malfunction with the “POWER” switch
If the “POWER” switch seems to be operating somewhat differently than usual,
such as the switch sticking slightly, there may be a malfunction. Contact your Lexus
dealer immediately.

1862-1. Driving procedures
