When driving ■
Auto current cut-off function
In case of over current, the auto cut-off function stops the power flowing to the
trailer lights to prevent damage to the vehicle’s electrical system.
This function is activated when the rated current of any of the following trailer light
circuit components is exceeded: ●
Tail lights: maximum 7.8 A ●
Stop/turn signal light (right): maximum 4.5 A●
Stop/turn signal light (left): maximum 4.5 A■
When the auto current cut function is activated
If a trailer light does not come on due to the activation of the auto current cut func-
tion, the light system will need to be reset.
Follow the reset procedure shown below. ●
If a tail light does not come on, turn off the headlight switch.●
If the right-side stop/turn signal light does not come on, put the turn signal in the
off position or remove foot from the brake pedal.●
If the left-side stop/turn signal light does not come on, put the turn signal in the
off position or remove foot from the brake pedal.
If the emergency flashers do not operate, press the emergency flasher switch to
turn them off.

Trailer towing tips
Your vehicle will handle differently when towing a trailer. Help to avoid an
accident, death or serious injury, keep the following in mind when towing:
● Speed limits for towing a trailer va ry 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 manual, 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
connections. Recheck after driving a short distance.
● Practice turning, stopping and reversing with th e trailer attached in an
area away from traffic until you be come accustomed to the feel of the
vehicle-trailer combination.
● Reversing with a trailer attached is difficult and requires practice. Grip
the bottom of the steering wheel and move your hand to the left to
move the trailer to the left. Move yo ur hand to the right to move the
trailer to the right. (This is gene rally opposite to reversing without a
trailer attached.) Avoid sharp or prolonged turning. Have someone
guide you when reversing to redu ce the risk of an accident.
● As stopping distance is increased when towing a trailer, vehicle-to-
vehicle distance should be increas ed. For each 10 mph (16 km/h) of
speed, allow at least one vehicle and trailer length.
● Avoid sudden braking as you may skid, resulting in the trailer jackknif-
ing and a loss of vehicle control. Th is is especially true on wet or slip-
pery surfaces.
● Avoid jerky starts or sudden acceleration.

When driving ■
Matching trailer ball height to trailer coupler height
■
Before towing
Check that the following conditions are met: ●
Ensure that your vehicle’s ti res are properly inflated. (  P. 8 1 5 )●
Trailer tires are inflated according to the trailer manufacturer’s recommenda-
tion.●
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 tongue weight,
overloading, 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
regulations. If they do not, install rear view mirrors appropriate for towing pur-
poses. 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 cou-
pler on the trailer.

CAUTION■
Hitch
Trailer hitch assemblies have different weight capacities established by the hitch
manufacturer. Even though the vehicle may be physically capable of towing a
higher weight, the operator must determin e the maximum weight rating of the par-
ticular hitch assembly and never exceed the maximum weight rating specified for
the trailer-hitch. Exceeding the maximum weight rating se t by the trailer-hitch man-
ufacturer can cause an accident resulting in death or serious personal injuries.■
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/provincial regulations.●
Never tap into your vehicle’s hydraulic system, as this will lower the vehicle’s brak-
ing effectiveness.●
Never tow a trailer without using a safety chain 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 wand ering 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. Direct ly splicing trailer li ghts may damage your
vehicle’s electrical system and cause a malfunction.
