Please consult your dealer when installin g trailer lights, as incorrect installation
may cause damage to the vehicle’s lights. Please take care to comply with your
state’s laws when installing trailer lights.
Your vehicle will handle differently when towing a trailer. Help to avoid an acci-
dent, death or serious injury, keep the following in mind when towing:
●Speed limits for towing a trailer vary by state or province. Do not exceed the
posted towing speed limit.
●Lexus recommends that the vehicle-trailer speed limit is 65 mph (104 km/h)
on a flat, straight, dry road. Do not exceed this limit, the posted towing speed
limit or the speed limit for your trailer as set forth in your trailer owner’s man-
ual, whichever is lowest. Instability of the towing vehicle-trailer combination
(trailer sway) increases as speed increases. Exceeding speed limits may cause
loss of control.
●Before starting out, check the trailer lights, tires and the vehicle-trailer con-
nections. Recheck after driving a short distance.
●Practice turning, stopping and reversing with the trailer attached in an area
away from traffic until you become accustomed to the feel of the vehicle-
trailer combination.

■Matching trailer ball height to trailer coupler height
■Before towing
Check that the following conditions are met:
●Ensure that your vehicle’s tires are properly inflated. ( P. 6 1 3 )
●Trailer tires are inflated according to the trailer manufacturer’s recommendation.
●All trailer lights work as required by law.
●All lights work each time you connect them.
●The trailer ball is set at the proper height for the coupler on the trailer.
●The trailer is level when it is hitched.
Do not drive if the trailer is not level, and check for improper to ngue weight, overload-
ing, worn suspension, or other possible causes.
●The trailer cargo is securely loaded.
●The rear view mirrors conform to all applicable federal, state/provincial or local regula-
tions. If they do not, install rear view mirrors appropriate for towing purposes.
No matter which class of tow hitch
applies, for a more safe trailer hookup,
the trailer ball setup must be the proper
height for the coupler on the trailer.

■When towing a trailer
Lexus recommends trailers with brakes that conform to any applicable federal and
state/provincial regulations.
●If the gross trailer weight exceeds unbraked TWR, trailer brakes are required. Lexus
recommends trailers with brakes that conform to all applicable federal and state/pro-
vincial regulations.
●Never tap into your vehicle’s hydraulic system, as this will lower the vehicle’s braking
effectiveness.
●Never tow a trailer without using a safety ch ain securely attached to both the trailer
and the vehicle. If damage occurs to the coupling unit or hitch ball, there is danger of
the trailer wandering into another lane.
NOTICE
■When installing a trailer hitch
Use only the position recommended by your Lexus dealer. Do not install the trailer
hitch on the bumper; this may cause body damage.
■Do not directly splice trailer lights
Do not directly splice trailer lights. Dire ctly splicing trailer lights may damage your
vehicle’s electrical system and cause a malfunction.

■Daytime running light system
●To make your vehicle more visible to other drivers during daytime driving, the daytime
running lights turn on automatically (at an in creased intensity) whenever the hybrid sys-
tem is started and the parking brake is releas ed with the headlight switch off or in the
“AUTO” position. (Illuminate brighter than the front parking lights.) Daytime running
lights are not designed for use at night.
Type A only: Daytime running lights can be turned off by operating the switch.
●If a turn signal light is in use, the daytime running light, on the same side, is turned off.
For emergency flashers, both are turned off.
●Compared to turning on the headlights, the daytime running light system offers greater
durability and consumes less electricity, so it can help improve fuel economy.
■Headlight control sensor
■Automatic light off system
●When the headlights come on: The headlights and tail lights turn off 30 seconds after a
door is opened and closed if the power switch is turned to ACCESSORY mode or
turned off. (The lights turn off immediately if on the key is pressed after all the doors
are locked.)
●When only the tail lights come on: The tail lights turn off automatically if the power
switch is turned to ACCESSORY mode or turned off and the driver’s door is opened.
To turn the lights on again, turn the power switch to ON mode, or turn the light switch off
once and then back to or .
■Automatic headlight leveling system (if equipped)
The level of the headlights is automatically ad justed according to the number of passen-
gers and the loading condition of the vehicle to ensure that the headlights do not inter-
fere with other road users.
■Light reminder buzzer
A buzzer sounds when the power switch is turned off or turned to ACCESSORY mode
and the driver’s door is opened while the lights are turned on.
■12-volt battery-saving function
In order to prevent the 12-volt battery of the vehicle from discharging, if the headlights
and/or tail lights are on when the power switch is turned off the 12-volt battery saving
function will operate and automatically turn off all the lights after approximately 20 min-
utes. When the power switch is turned to ON mode, the 12-volt battery-saving function
will be disabled.
When any of the following are performed, the 12-volt battery-saving function is canceled
once and then reactivated. All the lights w ill turn off automatically 20 minutes after the
12-volt battery-saving function has been reactivated:
●When the headlight switch is operated
●When a door is opened or closed
The sensor may not function properly if an
object is placed on the sensor, or anything that
blocks the sensor is affixed to the windshield.
Doing so interferes with the sensor detecting
the level of ambient light and may cause the
automatic headlight system to malfunction.
