When driving
■Rain drop sensor (vehicles equipped with the rain-sensing windshield wipers)
■If no windshield washer fluid sprays
Check that the washer nozzles are not blocked if there is washer fluid in the wind-
shield washer fluid reservoir.
■Customization
Settings (e.g. drip prevention function) can be changed. ( P. 3 9 5 )
CAUTION
■Caution regarding the use of windshield wipers in AUTO mode
The windshield wipers may operate unexpectedly if the sensor is touched or the
windshield is subject to vibration in AUTO mode. Take care that your fingers or any-
thing else do not become caugh t in the windshield wipers.
NOTICE
■When the windshield is dry
Do not use the wipers, as they may damage the windshield.

●The shift lever is in the D or 4,5, or 6 range of S. (vehicles with an automatic
transmission)
●Vehicle speed is between approximately 25 mph (40 km/h) and 125 mph
(200 km/h).
■Accelerating
The vehicle can be accelerated normally.
■Automatic cruise control cancellation
The set speed is automatically cancelled in any of the following situations.
●Actual vehicle speed falls more than 10 mph (16 km/h) below the preset vehicle
speed
At this time, the memorized set speed is not retained.
●Actual vehicle speed is below 25 mph (40km/h)
●VSC is activated
■Canceling and resuming regular acceleration
Cancel

■Sensor detection information
●Certain vehicle conditions and the surrounding environment may affect the
ability of the sensor to correctly detect obstacles. Particular instances where this
may occur are listed below.
• There is dirt, snow or ice on the sensor.
• The sensor is frozen.
• The sensor is covered in any way.
• The vehicle is leaning considerably to one side.
• On an extremely bumpy road, on an incline, on gravel, or on grass.
• The vicinity of the vehicle is noisy due to vehicle horns, motorcycle engines,
air brakes of large vehicles, or other loud noises producing ultrasonic waves.
• There is another vehicle equipped with parking assist sensors in the vicinity.
• The sensor is coated with a sheet of spray or heavy rain
• The vehicle is equipped with a fender pole or wireless antenna.
• Towing eyelets are installed.
• The bumper or sensor receives a strong impact.
• The vehicle is approaching a tall or curved curb.
• In addition to the examples above, th ere are instances in which, because of
their shapes, signs and other objects may be judged by the sensor to be
closer than they are.
●The shape of the obstacle may prevent th e sensor from detecting it. Pay particu-
lar attention to the following obstacles.
• Wires, fences, ropes etc.
• Cotton, snow and other materials that absorb radio waves
• Sharply-angled objects
•Low obstacles
• Tall obstacles with upper sections projec ting outwards in the direction of your
vehicle

2-5. Driving information
Cargo and luggage
Capacity and distributionCargo capacity depends on the to tal weight of the occupants.
(Cargo capacity) = (Total load capa city) — (Total weight of occupants)
■ Steps for determining correct load limit
Locate the statement “The combin ed weight of occupants and
cargo should never exceed xxx lb.” on your vehicle’s placard.
Determine the combined weight of the driver and passengers
that will be riding in your vehicle.
Subtract the combined weight of the driver and passengers from
xxx kilograms or xxx lb.
The resulting figure equals the available amount of cargo and lug-
gage load capacity.
For example, if the xxx amount equals 1400 lb. and there will be five
150 lb. passengers in your vehicle, the amount of available cargo and
luggage load capacity is 650 lb.
1400
 750 (150 5) = 650 lb.
Determine the combined weight of luggage and cargo being
loaded on the vehicle.
The weight may not safely exceed the available cargo and luggage load
capacity calculated in Step 4.
Take notice of the following information about storage precautions, cargo
capacity and load.
●Stow cargo and luggage in the tru nk 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.

2-5. Driving information
If your vehicle will be towing a trailer, load from your trailer will be
transferred to your vehicle. Consult this manual to determine how
this reduces the available cargo and luggage load capacity of
your vehicle.
Lexus does not recommend towing a trailer with your vehicle. Your
vehicle is not designed for trailer towing.
Example on your vehicle
Cargo capacity
Total load capacity
When 2 people with the combined weight of 366 lb. (166 kg) are riding
in your vehicle, which has a total load capacity of 825 lb. (374 kg), the
available amount of cargo and luggag e load capacity will be as follows:
825 lb. — 366 lb. = 459 lb. (374 kg —166 kg = 208 kg)
In this condition, if 3 more passengers with the combined weight of 388 lb.
(176 kg) get on, the available cargo and luggage load will be reduced as fol-
lows:
459 lb. — 388 lb. = 71 lb. (208 kg — 176 kg = 32 kg)
As shown in the above example, if the number of occupants increases,
the cargo and luggage load equaling the combined weight of the occu-
pants who got on later, by an amount. In other words, if an increase in the
number of occupants causes an excess of the total load capacity (com-
bined weight of occupants plus cargo and luggage load), you must
reduce the cargo and luggage on your vehicle.

Vehicle load limits
■Total load capacity and seating capacity
These details are also described on the tire and loading information label.
(  P. 285)
CAUTION
■Overloading the vehicle
Do not overload the vehicle.
It may not only cause damage to the tire s, but also degrade steering and braking
ability, resulting in an accident.
Vehicle load limits include total lo ad capacity, seating capacity, towing
capacity and cargo capacity.
■ Total load capacity: 825 lb. (374 kg)
Total load capacity means the combined weight of occupants, cargo and
luggage.
■ Seating capacity: 5 occupants (Front 2, Rear 3)
Seating capacity means the maximum number of occupants whose esti-
mated average weight is 150 lb. (68 kg) per person.
■Towing capacity
Lexus does not recommend towing a trailer with your vehicle.
■Cargo capacity
Cargo capacity may increase or decrease depending on the weight and
the number of occupants.
