■Driving in the rain
●Drive carefully when it is raining, because visibility will be reduced, the windows
may become fogged-up, and the road will be slippery.
●Drive carefully when it starts to rain, because 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 the tires and the road surface, preventing
the steering and brakes from operating properly.
■Breaking in your new Lexus
To extend the life of the vehicle, the following precautions are recommended to
observe:
●For the first 186 miles (300 km):
Avoid sudden stops.
●For the first 621 miles (1000 km):
• Do not drive at extremely high speeds.
• Avoid sudden acceleration.
• Do not drive continuously in the low range in the “S” position.
• Do not drive at a constant speed for extended periods.
■Operating your vehicle in a foreign country
Comply with the relevant vehicle registration laws and confirm the availability of the
correct fuel. (→P. 566)

■When starting on an incline
The hill-start assist control may operate. (→P. 2 1 4 )
■For efficient use
●Put the shift lever into “D” when driving
In the “N” position, the gasoline engine operates but electricity cannot be gen-
erated. The hybrid battery (traction battery) will be discharged requiring unnec-
essary 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 traction motor without 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.
●Put the shift lever into “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 the time may
discharge the hybrid battery. The vehicle cannot run if the hybrid battery is dis-
charged.
■Normal characteristics after turning off the hybrid system
Approximately five hours after the hybrid system is turned off, you may hear sound
coming from under the vehicle for several minutes. This is because the fuel evapo-
ration leakage check is performed. It does not indicate a malfunction.

pedal and move the shift lever.
■ Shift position uses
*1: To improve fuel consumption and reduce noises, set the shift lever in the
“D” position for normal driving.
*
2: By selecting shift ranges using “S” mode, you can control engine braking forces.

Trip information■ Driving range
■ Average fuel consumption after refueling
■ Current fuel consumption
■ Average vehicle speed
Displays the estimated maximum distance that can
be driven with the quantity of fuel remaining.
• 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 added to the tank, the display may not be updated.
Displays the average fuel consumption since the
vehicle was last refueled.
Displays the current rate of fuel consumption.
Displays the average vehicle speed since the hybrid
system was last started. Display items can be switched

2-5. Driving information
Cargo and luggage
Capacity and distributionCargo capacity depends on the total weight of the occupants.
(Cargo capacity) = (Total load capacity) — (Total weight of occupants)
Steps for Determining Correct Load Limit—
(1) Locate the statement “The combined weight of occupants and cargo should never exceed XXX kg or XXX lbs.” on your vehicle’s
placard.
(2) Determine the combined weight of the driver and passengers that will be riding in your vehicle.
(3) Subtract the combined weight of the driver and passengers from XXX kg or XXX lbs.
Take notice of the following information about storage precautions, cargo
capacity and load.
●Stow cargo and luggage in the trunk whenever possible. Be sure all
items are secured in place.
● Be careful to keep the vehicle level. Placing the weight as far for-
ward as possible helps maintain vehicle balance.
● For better fuel economy, do not carry unnecessary weight.

4-1. Maintenance and care
Cleaning and protecting the vehicle exterior
■Automatic car washes
●Fold the mirrors back before washing the vehicle.
●Brushes used in automatic car washes may scratch the vehicle surface and
harm your vehicle’s paint.
●Before entering an automatic car wash, check that the fuel filler door is closed.
■High pressure washers
Do not allow the nozzles of the washers to come within close proximity of the win-
dows and fuel filler door.
Perform the following to protect the vehicle and maintain it in prime condi-
tion.
●Working from top to bottom, liberally apply water to the vehicle
body, wheel wells and underside of the vehicle to remove any dirt
and dust.
Wash the vehicle body using a sponge or soft cloth, such as a chamois.
●For hard-to-remove marks, use car wash soap and rinse thor-
oughly with water.
● Wipe away any water.
● Wax the vehicle when the waterproof coating deteriorates.
If water does not bead on a clean surface, apply wax when the vehicle
body is cool.
