When driving
Connecting trailer lights
Without towing package: Please consult your dealer when installing
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.
With towing package: Use the 4 pin connector located under the rear
bumper.
nAuto current cut-off function (vehicles with towing package)
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:
lTail lights: maximum 7.8 A
lStop/turn signal light (right): maximum 4.5 A
lStop/turn signal light (left): maximum 4.5 A
nWhen 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.
lIf a tail light does not come on, turn off the headlight switch.
lIf 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.
lIf 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.
After the light system is reset, operate the light switches again to see if the lights
operate normally.
If the lights do not operate normally, have the vehicle inspected by your Lexus
dealer.

Trailer towing tips
Your vehicle will handle differently when towing a trailer. In order to avoid
accident, death or serious injury, keep the following in mind when towing:
lBefore starting out, check the trailer lights and the vehicle-trailer con-
nections. Recheck after driving a short distance.
lPractice turning, stopping and reversing with the trailer attached in an
area away from traffic until you become accustomed to the feel of the
vehicle.
lReversing 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 your hand to the right to move the
trailer to right. (This is generally opposite to reversing without a trailer
attached.) Avoid sharp or prolonged turning. Have someone guide
you when reversing to reduce the risk of an accident.
lAs stopping distance is increased when towing a trailer, vehicle-to-
vehicle distance should be increased. For each 10 mph (16 km/h) of
speed, allow at least one vehicle and trailer length.
lAvoid sudden braking as you may skid, resulting in jackknifing and loss
of control. This is especially true on wet or slippery surfaces.
lAvoid jerky starts or sudden acceleration.
lAvoid jerky steering and sharp turns, and slow down before making
turns.
lNote that when making a turn, the trailer wheels will be closer than the
vehicle wheels to the inside of the turn. Compensate by making a
larger than normal turning radius.

2-5. Driving information
lWhen restarting after parking on a slope:
With the transmission in the P position, start the engine. Be sure
to keep the brake pedal depressed.
Shift into 3, 2, 1, or the R position (if reversing).
Release the parking brake and brake pedal, and slowly pull or
back away from the wheel blocks. Stop and apply the brakes.
Have someone retrieve the blocks.
nBefore towing
Check that the following conditions are met:
lThe vehicle's tires are properly inflated. (→P. 4 8 7 )
lTrailer tires are inflated according to the trailer manufacturer's recommendation.
lAll trailer lights work.
lAll lights work each time you connect them.
lThe trailer ball is set up at the proper height for the coupler on the trailer.
lThe vehicle remains level when a loaded or unloaded trailer is hitched. Do not
drive if the vehicle is not level, and check for improper tongue load, overloading,
worn suspension, or other possible causes.
lThe trailer cargo is securely loaded.
lThe 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.
nBreak-in schedule
If your vehicle is new or equipped with any new power train components (such as
an engine, transmission, differential and wheel bearing), Lexus recommends that
you do not tow a trailer until it has been driven for over 500 miles (800 km).
However, avoid full throttle acceleration.
nMaintenance
lIf you tow a trailer, your vehicle will require more frequent maintenance due to
the additional load. (See “Warranty and Services Guide”, “Owner's Manual Sup-
plement” or “Scheduled Maintenance”.)
lRetighten the fixing bolts of the towing ball and bracket after approximately 600
miles (1000 km) of trailer towing.

CAUTION
nHitches
lIf you wish to install a trailer hitch, contact your Lexus dealer.
lUse only a hitch that conforms to the gross trailer weight requirement.
lFollow the directions supplied by the hitch manufacturer.
lLubricate the hitch ball with a light coat of grease.
lRemove the trailer hitch whenever you are not towing a trailer. After removing
the hitch, seal any mounting hole in the vehicle body to prevent entry of any sub-
stances into the vehicle.
nWhen towing a trailer
lIf the gross trailer weight exceeds 1000 lb. (450 kg), trailer brakes are required.
Lexus recommends trailers with brakes that conform to all applicable federal and
state/provincial regulations.
lNever tap into your vehicle's hydraulic system, as this will lower the vehicle's
braking effectiveness.
lNever 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 wandering into another lane.

When driving
NOTICE
nWhen installing a trailer hitch
lUse only the position recommended by your Lexus dealer. Do not install the
trailer hitch on the bumper; this may cause body damage.
lDo not use axle-mounted hitches, as they can cause damage to the axle housing,
wheel bearings, wheels or tires.
nSafety chain
A safety chain must always be used between the towing vehicle and the trailer.
Leave sufficient slack in the chain for turns. The chain should cross under the trailer
tongue to prevent the tongue from dropping to the ground in the case that it
becomes damaged or separated. For the correct safety chain installation proce-
dure, ask your Lexus dealer.
nDo not directly splice trailer lights
Directly splicing trailer lights may damage your vehicle's electrical system and
cause a malfunction.
