◆Weight limits
Check the allowable towing capacity, GVM (Gross Vehicle Mass), MPAC
(Maximum Permissible Axle Capacity), and permissible draw bar load before
towing. ( P. 644)
◆Towing hitch/bracket
Lexus recommends the use of the Lexus hi tch/bracket for your vehicle. Other
products of a suitable nature and comparable quality may also be used.
◆To prevent an accident
The handling of the vehicle will feel diff erent when towing a trailer. Beware of
the 3 most common causes of towing-rel ated accidents: driver error, exces-
sive speed, and overloading.
Trailer towing (vehicles with a towing package)
The strain of towing a trailer will have a negative impact on the running perfor-
mance, handling, fuel consumption and endurance of your vehicle. Use the
vehicle features in the correct manner and operate the vehicle with care for
safer driving and optimal comfort. Dama ge and/or malfunctions that occur as
a result of towing performed for comme rcial purposes are not covered by the
Lexus warranty.
Ask your local authorized Lexus retailer or Lexus authorized repairer, or any
reliable repairer for furthe r details before towing, as there are additional legal
requirements in some countries.

■Total trailer weight and permissible drawbar load
Total trailer weight
Weight of the traile r itself plus the trailer load should be within the max-
imum towing capacity. Exceeding
this weight is dangerous. ( P. 644)
When the total trailer weight is
greater than the vehicle weight, we
recommend the use of a friction sta- bilizer (sway control device).
Permissible drawbar load
Allocate the trailer load so that the drawba r load is greater than 25 kg (55.1 lb.) or
4% of the towing capacity. Do not let the drawbar load exceed the indicated weight. ( P. 644)
■Information tag (manufacturer’s label)
Gross vehicle mass
The combined weight of the driver, passengers, luggage, towing hitch, total curb
mass and drawbar load should not exceed the gross vehicle mass by more than
100 kg (220.5 lb.). Exceedin g this weight is dangerous.
Maximum permissible rear axle capacity
The weight borne by the rear axle should not exceed the maximum permissible
rear axle capacity by 15% or more. Exceeding this weight is dangerous.
The values for towing capacity were derived from testing conducted at sea level. Take note that engine output and towing capacity will be reduced at high altitudes.

WARNING
■When the gross vehicle mass or maximum permissible axle capacity is exceeded
Failing to observe this precau tion may lead to an accident causing death or serious
injury.
●Add an additional 20.0 kPa (0.2 kgf/cm2 or bar, 3 psi) to the recommended tire infla- tion pressure value. ( P. 652)
●Do not exceed the established speed limit for towing a trailer in built-up areas or 100
km/h (62 mph), whic hever is the lower.

■Tire information
●Increase the tire inflation pressure to 20.0 kPa (0.2 kgf/cm2 or bar, 3 psi) greater than
the recommended value when towing. ( P. 652)
●Increase the air pressure of the trailer tires in accordance with the total trailer weight
and according to the values recommended by the manufacturer of your trailer.
■Break-in schedule
Lexus recommends that vehicles fitted with new power train components should not be
used for towing trailers for the first 800 km (500 miles).
■Safety checks before towing
●Check that the maximum load limit for the towing hitch/bracket hitch ball is not
exceeded. Bear in mind that the coupling weight of the trailer will add to the load
exerted on the vehicle. Also make sure that you will not be towing a load that exceeds the maximum permissible axle capacity.
●Ensure that the trailer load is secure.
●Supplementary outside rear view mirrors shou ld be added to the vehicle if the traffic behind cannot be clearly seen with standa rd mirrors. Adjust the extending arms of
these mirrors on both sides of the vehicle so that they always provide maximum visibility
of the road behind.
■Maintenance
●Maintenance must be performed more frequently when using the vehicle for towing
due to the greater weight burden placed on the vehicle compared to normal driving.
●Retighten all bolts securing the hitching ball and bracket after towing for approximately
1000 km (600 miles).
NOTICE
■When the rear bumper strengthening material is aluminum
Ensure the steel bracket part does not come directly in contact with that area.
When steel and aluminum come into contact, there is a reaction similar to corrosion,
which will weaken the section concerned and may result in damage. Apply a rust inhib- itor to parts that will come in contact when attaching a steel bracket.
