scription terms is available; charges vary
by subscription term selected and loca-
tion.
●Automatic Collision Notification, Emer-
gency Assistance and Stolen Vehicle

■When contacting the response center
You may be unable to contact the response
center if the network is busy.
When the engine switch is turned to
IGNITION ON mode, the red indica-
tor light comes on for 2 seconds then
turns off. Afterward, the green indica-

severe rear-end collision, the system is
designed to automatically call the
response center. The responding agent
receives the vehicle’s location and
attempts to speak with the vehicle
occupants to assess the level of emer-
gency. If the occupants are unable to
communicate, the agent automatically
treats the call as an emergency, con-
tacts the nearest emergency services
provider to describe the situation, and
requests that assistance be sent to the
Safety Connect LED light Indi-
cators

1143-2. 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 battery from being dis-
charged while the vehicl e is not in operation
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 engine
immobilizer system use weak radio waves.
In the following situations, the communica-
tion between the electronic key and the
vehicle may be affected, preventing the
smart access system with push-button start,
wireless remote control and engine immo-
bilizer system from operating properly.
(Ways of coping: P.421)

■Matching trailer ball height to trailer
coupler height
No matter which class of tow hitch applies,
Trailer towing (vehicles with-
out towing package)
Lexus does not recommend towing
a trailer with your vehicle. Lexus
also does not recommend the
installation of a tow hitch or the use
of a tow hitch carrier for a wheel-
chair, scooter, bicycle, etc. Your
vehicle is not desi gned for trailer
towing or for the use of tow hitch
mounted carriers.
Trailer towing (vehicles with
towing package)
Your vehicle is designed primarily
as a passenger-and-load-carrying
vehicle. Towing a tr ailer can have an
adverse impact on handling, per-
formance, braking, durability, and
fuel consumption. For your safety
and the safety of others, you must
not overload your vehicle or trailer.
You must also ensure that you are
using appropriate towing equip-
ment, that the towing equipment
has been installed correctly and
used properly, and that you employ
the requisite driving habits.
Vehicle-trailer stability and braking
performance are affe cted by trailer
stability, brake performance and
setting, trailer brakes, the hitch and
hitch systems (if equipped).
To tow a trailer safely, use extreme
care and drive the vehicle in accor-
dance with your tr ailer’s character-
istics and operating conditions.
Lexus warranties do not apply to
damage or malfunction caused by
towing a trailer for commercial pur-
poses.
Contact your Lexus dealer for fur-
ther information about additional
requirements such as a towing kit,
etc.

1684-1. Before driving
mance when using engine braking,
do not put the transmission in D. If in
the M mode, the transmission shift
range position must be in 6 or lower.
( P.174)
 Instability happens more frequently
when descending steep or long
downhill grades. Before descend-
ing, slow down and downshift. Do
not make sudden downshifts while
descending steep or long downhill
grades.
 Avoid holding the brake pedal down
too long or applying the brakes too
frequently. This could cause the
brakes to overheat and result in
reduced braking efficiency.
 Due to the added load of the trailer,
your vehicle’s engine may overheat
on hot days (at temperatures over
85°F [30°C]) when driving up a
long or steep grade. If the engine
coolant temperature gauge indi-
cates overheating, immediately turn
off the air conditioning (if in use),
pull your vehicle off the road and
stop in a safe spot. ( P.426)
 Always place wheel blocks under
both the vehicle’s and the trailer’s
wheels when parking. Put the trans-
mission in P and apply the parking
brake. Avoid parking on a slope, but
if unavoidable, do so only after per-
forming the following:
1 Apply the brakes and keep them
applied. 2
Have someone place wheel blocks
under both the vehicle’s and trailer’s
wheels.
3 When the wheel blocks are in
place, release the brakes slowly
until the blocks absorb the load.
4 Shift into P and apply the parking
brake.
5 Turn off the engine.
 When restarting after parking on a
slope:
1 With the transmission in P, start the
engine. Be sure to keep the brake
pedal depressed.
2 Shift into a forward gear. If revers-
ing, shift into R.
3 If the parking brake is in manual
mode, release the parking brake.
( P.179)
4 Release the brake pedal, and slowly
pull or back away from the wheel
blocks. Stop and apply the brakes.
5 Have someone retrieve the blocks.

■If a warning message is displayed on the multi-information display
A system may be temporarily unavailable or there may be a malfunction in the system.
●In the following situations, perform the actions specified in the table. When the normal
operating conditions are detected, the message will disappear and the system will
become operational.
If the message does not disappear, contact your Lexus dealer.
SituationActions
When the area around a camera is covered
with dirt, moisture (f ogged up, covered with
condensation, ice, etc. ), or other foreign
matterUsing the wiper and A/C function, remove
the dirt and other attached matter.
(  P.286)
When the temperature around the front
camera is outside of the operational range,
such as when the vehicle is in the sun or in an
extremely cold environment
If the front camera is hot, such as after the
vehicle had been parked in the sun, use the
air conditioning system to decrease the tem-
perature around the front camera.
If a sunshade was used when the vehicle
was parked, depending on its type, the sun-
light reflected from the surface of the sun-
shade may cause the temperature of the
front camera to become excessively high.
If the front camera is cold, such after the
vehicle is parked in an extremely cold envi-
ronment, use the air conditioning system to
increase the temperature around the front
camera.
