1263-2. Opening, closing and locking the doors
■If “Key Left inside Vehicle” is shown on
the multi-information display
An attempt was made to lock the doors
using the smart access system with
push-button start while the electronic key
was still inside the vehicle. Retrieve the elec-
tronic key from the vehicle and lock the
doors again.
■Battery-saving function
The battery-saving fu nction 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
access system with pu sh-button start may
take some time to unlock the doors.
• The electronic key has been left in an
area of approximately 6 ft. (2 m) of the
outside of the vehicle for 10 minutes or
longer.
• The smart access system with push-but- ton start has not been used for 5 days or
longer.
●If the smart access system with push-but-
ton start has not been used for 14 days or
longer, the doors cannot be unlocked at
any doors except the driver’s door. In this
case, take hold of the driver’s door han-
dle, or use the wirele ss remote control or
the mechanical key, to unlock the doors.
■Turning an electronic key to bat-
tery-saving mode
When battery-saving mode is set, battery
depletion is minimized by stopping the elec-
tronic key from re ceiving radio waves. Press twice while pressing and holding
. Confirm that the electronic key indica-
tor flashes 4 times.
While the battery-saving mode is set, the
smart access system with push-button start
cannot be used. To cancel the function,
press any of the electronic key buttons.
■Conditions affecting operation
The smart access system with push-button
start, wireless remote control and immobi-
lizer system use weak radio waves. In the
following situations, the communication
between the electronic key and the vehicle
may be affected, preventing the smart
access system with push-button start, wire-
less remote control and immobilizer system
from operating properly. (Ways of coping:
P.439)
●When the electronic key battery is
depleted
●Near a TV tower, electric power plant,
gas station, radio station, large display,
airport or other fac ility that generates
strong radio waves or electrical noise

To set the mirror angle used when the vehi-
cle is reversing, adjust the mirror angle at a
desired position with the shift lever in R.
The adjusted angle will be memorized and
the mirror will automatically tilt to the mem-
orized angle whenever the shift lever is
shifted to R from next time.
The memorized downward tilt position of
the mirror is linked to the normal position
(angle adjusted with th e shift lever in other
than R). Therefore, if the normal position is
changed after adjustment, the tilt position
will also change.
When the normal position is changed, read-
just the angle in reversing.
Push the mirror back in the direction of

hybrid system output may be restrained.
●A warning message is displayed on the
multi-information display and head-up
display (if equipped) while the system is
operating.
■Restraining sudden start (Drive-Start
Control)
●When the following unusual operation is
performed, the hybrid system output may
be restrained.
• When the shift lever is shifted from R to D,
D to R, N to R, P to D, or P to R (D
includes S) with the accelerator pedal
depressed, a warning message appears
on the multi-information display and
head-up display (if equipped). If a warn-
ing message is shown on the multi-infor-
mation display and head-up display (if
equipped), read the message and follow
the instructions.
• When the accelerator pedal is depressed
too much while the vehicle is in reverse.
●While Drive-Start Control is being acti-
vated, your vehicle may have trouble
escaping from the mud or fresh snow. In
such case, deactivate TRAC ( P.280)
to cancel Drive-Start Control so that the
vehicle may become able to escape from
the mud or fresh snow.
■Breaking in your new Lexus
To extend the life of the vehicle, observing
the following precautions is recommended:
●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.
■Operating your vehicle in a foreign
country
Comply with the relevant vehicle registra-
tion laws and confirm the availability of the
correct fuel. ( P.454)
■Eco-friendly driving
P.85
WARNING
Observe the following precautions.
Failure to do so may result in death or
serious injury.
■When starting the vehicle
Always keep your foot on the brake
pedal while stopped with the “READY”
indicator is illuminated. This prevents the
vehicle from creeping.
■When driving the vehicle
●Do not drive if you are unfamiliar with
the location of the brake and accelera-
tor pedals to avoid depressing the
wrong pedal.
• Accidentally depressing the accelera- tor pedal instead of the brake pedal
will result in sudden acceleration that
may lead to an accident.
• When backing up, you may twist your body around, leading to a difficulty in
operating the pedals. Make sure to
operate the pedals properly.
• Make sure to keep a correct driving posture even when moving the vehicle
only slightly. This allows you to depress
the brake and accelerator pedals
properly.
• Depress the brake pedal using your right foot. Depressing the brake pedal
using your left foot may delay
response in an emer gency, resulting in
an accident.
●The driver should pay extra attention
to pedestrians when the vehicle is
powered only by the electric motor
(traction motor). As there is no engine
noise, the pedestrians may misjudge
the vehicle’s movement. Even though
the vehicle is equipped with the
Acoustic Vehicle Alerting System,
drive with care as pedestrians in the
vicinity may still not notice the vehicle if
the surrounding area is noisy.

1684-1. Before driving
gage load capacity calculated in Step
4.
(6) 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 lug-
gage load capacity of your vehicle.
( P.170)
Vehicles without towing package: Lexus
does not recommend towing a trailer with
your vehicle. Your vehicle is not designed
for trailer towing.
Cargo capacity
Total load capacity (vehicle capac-
ity weight) ( P.452)
When 2 people with the combined
weight of A lb. (kg) are riding in your
vehicle, which has a total load capacity
(vehicle capacity weight) of B lb. (kg),
the available amount of cargo and lug-
gage load capacity will be C lb. (kg) as
follows:
B
*2 lb. (kg) - A*1 lb. (kg) = C*3 lb. (kg)
*1: A =Weight of people
*2: B =Total load capacity
*3:C =Available carg o and luggage load
In this condition, if 3 more passengers with
the combined weight of D lb. (kg) get on,
the available cargo and luggage load will
be reduced E lb. (kg) as follows:
C lb. (kg) - D*4 lb. (kg) = E*5 lb. (kg)
*4: D =Additional weight of people
*5: E =Available cargo and luggage load
As shown in the example above, if the
number of occupant s increases, the
cargo and luggage load will be
reduced by an amount that equals the
increased weight due to the additional
occupants. In other words, if an
increase in the number of occupants
causes an excess of the total load
capacity (combined weight of occu-
pants plus cargo and luggage load),
you must reduce the cargo and lug-
gage on your vehicle.

WARNING
■Things that must not be carried in the
luggage compartment
The following things may cause a fire if
loaded in the luggage compartment:
●Receptacles containing gasoline
●Aerosol cans
■Storage precautions
Observe the following precautions.
Failure to do so may prevent the pedals
from being depressed properly, may
block the driver’s visi on, or may result in
items hitting the driver or passengers,
possibly causing an accident.
●Stow cargo and luggage in the lug-
gage compartment whenever possi-
ble.
