Trailer towing
Your vehicle is designed primarily as a passenger-and-load carrying vehi-
cle. Towing a trailer will have an adverse effect on handling, performance,
braking, durability, and fuel consumption. For your safety and the safety of
others, do not overload the vehicle or trailer.
Lexus warranties do not apply to damage or malfunction caused by towing
a trailer for commercial purposes.
■ Weight limits
Confirm that the total trailer weight, gross vehicle weight, gross axle
weight and trailer tongue load are all within the limits.
■ Gross vehicle weight
The gross vehicle weight must not exceed the Gross Vehicle Weight
Rating (GVWR) indicated on the Certification Label. The gross
vehicle weight is the sum weight of the unloaded vehicle, driver, pas-
sengers, luggage, hitch and trailer tongue load. Also included is the
weight of any special equipment installed on your vehicle.
■ Gross axle weight
The load on either the front or rear axle resulting from distribution of
the gross vehicle weight on both axles must not exceed the Gross
Axle Weight Rating (GAWR) listed on the Certification Label.

Towing a trailerContact your Lexus dealer for further information about additional
requirements such as a towing kits, etc.
Hitch and tow hitch receiver■ Hitch
Trailer hitch assemblies have different weight capacities established by
the hitch manufacturer. Even though the vehicle may be rated for tow-
ing a higher weight, the operator must never exceed the maximum
weight rating specified for the trailer hitch.
■Trailer tongue load
The trailer cargo load should be distributed so that the tongue load
is 9 to 11% for weight carrying hitch or 15% for weight distributing
hitch of the total trailer weight, not exceeding the following.
Weight carrying hitch: 650 lb. (294 kg)
Weight distributing hitch: 975 lb. (442 kg)
(Tongue load/Total trailer weight x 100 = 9 to 11% or 15%)
The total trailer weight and tongue load can be measured with plat-
form scales found at a highway weighing stations, building supply
companies, trucking companies, junk yards, etc.

When driving
CAUTION
■To avoid accident or injury
●The total trailer weight (trailer weight plus the weight of cargo) must not exceed
6500 lb. (2948 kg).
●If a trailer and cargo weight over 2000 lb. (907 kg), use a sway control device
with sufficient capacity.
●The gross combined weight (sum of your vehicle weight plus its load and the total
trailer weight) must not exceed 12000 lb. (5443 kg).
●Do not exceed the trailer hitch assembly weight, gross vehicle weight, gross axle
weight and trailer tongue load capacities.
●Never load more weight in the back than in the front of the trailer. About 60% of
the load should be in the front half of the trailer, and the remaining 40% in the
rear.
●Set the vehicle height to the “LO” mode and turn off the rear height control air
suspension to prevent the vehicle height from automatically changing.
●The tow hitch receiver installed on your vehicle must never be used on another
vehicle
■Hitches
●If you wish to install a trailer hitch, contact your Lexus dealer.
●Use only a hitch that conforms to the total trailer weight requirement.
●Follow the directions supplied by the hitch manufacturer.
●Lubricate the hitch ball with a light coat of grease.
●Remove 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.
■When towing a trailer
●If the total trailer weight exceeds 1000 lb. (453 kg), trailer brakes are required.
●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 wandering into another lane.

• Persons with sensitive skin
• Persons who are fatigued
• Persons who have taken alcohol or drugs that induce sleep (sleeping drugs,cold remedies, etc.)

Maintenance and care
■Replacing tires and wheels
If the ID code is not registered, the system will not work properly. After about 20
minutes, the tire pressure warning light comes on after blinking for 1 minute to indi-
cate a system malfunction.
■Tire life
Any tire over 6 years old must be checked by a qualified technician even if they
have seldom or never been used or damage is not obvious.
■If the treadwears down below 0.16 in. (4 mm) on snow tires
The effectiveness of snow tires is lost.
■Maximum load of tire
Check that the maximum load of the replaced tire is greater than 1 /2 of the Gross
Axle Weight Ratings (GAWR) of either the front axle or the rear axle, whichever is
greater.
As for the maximum load of the tire, see the load limit at maximum cold tire inflation
pressure mentioned on the sidewall of the tire, and as for the Gross Axle Weight
Ratings (GAWR), see the Certification Label. (
