Before driving CAUTION■
When installing a child restraint system
Follow the directions given in the child re straint system installa tion manual and fix
the child restraint system securely in place.
If the child restraint system is not correctl y fixed in place, the child or other passen-
gers may be injured or even killed in the event of sudden braking, sudden swerving
or an accident.
●
When installing a child restraint system in the rear center seat, adjust both seat
cushions to the same position and align both seatbacks at the same angle. The
seatbacks must be adjusted to the same angle. Otherwise, the child restraint sys-
tem cannot be securely restrained and this may cause death or serious injuries in
the event of sudden braking, sudden swerving or an accident.
●
When using the LATCH system, move the seat as far back as possible and adjust
the seatback as upright as possible.
●
When a booster seat is installed, always ensure that the shoulder belt is posi-
tioned across the center of the child's shoulder. The belt should be kept away
from the child's neck, but not so that it could fall off the child's shoulder. Failing to
do so may result in death or serious inju ry in the event of sudden braking, sudden
swerving or an accident. ●
If the driver’s seat interferes with the child
restraint system and prevents it from being
attached correctly, attach the child restraint
system to the right-hand rear seat. ●
Adjust the front passen ger seat so that it
does not interfere with the child restraint
system. ●
Only put a forward-facing child restraint
system on the front seat when unavoidable.
When installing a forward-facing child
restraint system on the front passenger
seat, move the seat as far back as possible
even if the “AIR BAG OFF” indicator light is
illuminated. Failure to do so may result in
death or serious injury if the airbags deploy
(inflate).

1641-8. Safety information
CAUTION■
When installing a child restraint system ●
Ensure that the belt and tab are securely locked and the seat belt is not twisted.●
Shake the child restraint system left and right, and forward and backward to
ensure that it has be en securely installed.●
After securing a child restraint system, never adjust the seat.●
Follow all installation instructions provid ed by the child restraint system manufac-
turer.■
Do not use a seat belt extender
If a seat belt extender is used when inst alling a child restraint system, the seat belt
will not securely hold the child restraint system, which could cause death or serious
injury to the child or other passengers in the event of sudden braking, sudden
swerving or an accident.■
To correctly attach a child restraint system to the anchors
When using the LATCH anchors, be sure that there are no foreign objects around
the anchors and that the seat belt is no t caught behind the child restraint system.
Make sure the child restraint system is se curely attached, or it may cause death or
serious injury to the child or other passen gers in the event of a sudden stop, sudden
swerve or accident.

1722-1. Driving procedures
CAUTION■
When the vehicle is stopped ●
Do not depress the accelerator pedal unnecessarily.
If the vehicle is in any gear other than P or N, the vehicle may accelerate suddenly
and unexpectedly, causing an accident.●
Do not leave the vehicle with the hybrid system on for a long time.
If such a situation cannot be avoided, park the vehicle in an open space and
check that exhaust fumes do no t enter the vehicle interior.●
In order to prevent accidents due to the vehicle rolling away, always keep
depressing the brake pedal while the “READY” indicator is on. Apply the parking
brake as necessary.●
If the vehicle is stopped on an incline, in order to prevent accidents caused by the
vehicle rolling forward or backward, always depress the brake pedal and securely
apply the parking brake as needed.●
Avoid revving or racing the engine.
Running the engine at high speed while the vehicle is stopped may cause the
exhaust system to overheat, which could result in a fire if combustible material is
nearby.

1742-1. Driving procedures
CAUTION■
Exhaust gases
Exhaust gases include harmfu l carbon monoxide (CO) th at is colorless and odor-
less. Inhaling exhaust gases may lead to death or a serious health hazard. ●
If the vehicle is in a poorly ventilated area, stop the hybrid system. In a closed
area, such as a garage, exhaust gases may collect and enter the vehicle. This may
lead to death or a serious health hazard.●
The exhaust system should be checked occasionally. If there is a hole or crack
caused by corrosion, damage to a joint or abnormal exhaust noise, be sure to
have the vehicle inspected and repaired by your Lexus dealer . Failure to do so
may allow exhaust gases to enter the vehicl e, resulting in death or a serious health
hazard.■
When taking a nap in the vehicle
Always turn the hybrid system off. Otherwise, if you accidentally move the shift
lever or depress the accelerator pedal, this could cause an accident or fire due to
hybrid system overheating. Additionally, if the vehicle is parked in a poorly venti-
lated area, exhaust gases may collect and enter the vehicle, leading to death or a
serious health hazard.■
When braking the vehicle ●
When the brakes are wet, drive more cautiously.
Braking distance increases when the brakes are wet, and this may cause one side
of the vehicle to brake differently than the other side. Also, the parking brake may
not securely hold the vehicle.●
If the electronically controlled brake syst em does not operate, do not follow other
vehicles closely and avoid hills or sharp turns that require braking.
In this case, braking is still possible, but the brake pedal should be depressed
more firmly than usual. Also, the braking distance will increase. Have your brakes
fixed immediately.
●
The brake system consists of 2 or more individual hydraulic systems; if one of the
systems fails, the other(s) wi ll still operate. In this case, the brake pedal should be
depressed more firmly than usual and the braking distance will increase. Have
your brakes fixed immediately.

2962-5. Driving information
Cargo and luggage
Capacity and distribution
Cargo 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 
(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 th e 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.
(4)The resulting figure equals the av ailable amount of cargo and luggage
load capacity.
For example, if the “XXX” amount equals 1400 lbs. and there will be
five 150 lb passengers in your ve hicle, the amount of available cargo
and luggage load capacity is 650 lbs. (1400  750 (5  150) = 650
lbs.)
(5)Determine the combined weight of luggage and cargo being loaded
on the vehicle. That weight may no t 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 luggage compartment 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.
