Trailer towing (vehicles with towing package)
◆Weight limits
Check the allowable towing capacity, GVM (Gross Vehicle Mass), MPAC
(Maximum Permissible Axle Capacity), and permissible drawbar load before
towing. ( P. 546)
◆Towing hitch/bracket
Lexus recommends the use of the Lexus hitch/bracket for your vehicle. Other
products of a suitable nature and comparable quality may also be used.
Your vehicle is designed primaril y as a passenger carrying vehicle.
Towing a trailer will have an adverse effect on handling, performance, brak-
ing, durability, and fuel consumption. Your safety and satisfaction depend on
the proper use of correct equipment and cautious driving habits. For your
safety and the safety of others, do not overload the vehicle or trailer.
To tow a trailer safely, use extreme care and drive the vehicle in accordance
with the trailer’s characteristics and operating conditions.
Lexus warranties do not apply to damage or malfunction caused by towing a
trailer for commercial purposes.
Ask your local authorized Lexus retailer or Lexus authorized repairer, or any
reliable repairer for further 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 trailer itself plus the trailer load should be within the max-
imum towing capacity. Exceeding this weight is dangerous. ( P. 546)
When towing a trailer, use a friction
coupler or friction stabilizer (sway control device).
Permissible drawbar load
Allocate the trailer load so that the drawbar load is greater than 25 kg (55.1 lb.) or4% of the towing capacity. Do not let the drawbar load exceed the indicatedweight. ( P. 546)
■Information tag (manufacturer’s label)
Gross vehicle mass
The combined weight of the driver, passengers, towing hitch, luggage,
total curb mass and drawbar load should not exceed the gross vehiclemass by more than 100 kg (220.5
lb.). Exceeding this weight is danger- ous.
Maximum permissible rear axle capacity
The weight borne by the rear axle should not exceed the maximum permissibleaxle 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 limit or maximum permissible axle capacity is exceeded
Do not exceed the established speed limit fo r towing a trailer in built-up areas or 100 km/h (62 mph), whichever is lower.
Failing to observe this precaution may lead to an accident causing death or serious injury.

3304-5. Using the driving support systems
GS450h_300h_OM_OM30F92E_(EE)
WARNING
■When the VSC is activated
The slip indicator light flashes. Always drive carefully. Reckless driving may cause an accident. Exercise particular care when the indicator light flashes.
■When the TRC/VSC systems are turned off
Be especially careful and drive at a speed appropriate to the road conditions. As these are the systems to help ensure vehicle stability and driving force, do not turn the TRC/
VSC systems off unless necessary.
■Replacing tires
Make sure that all tires are of the specified size, brand, tread pattern and total load
capacity. In addition, make sure that the tires are inflated to the recommended tire infla- tion pressure level.
The ABS, TRC and VSC systems will not function correctly if different tires are installed
on the vehicle. Contact any authorized Lexus retailer or Lexus authorized repairer, or any reliable repairer for further information when replacing tires or wheels.
■Handling of tires and the suspension
Using tires with any kind of problem or modi fying the suspension will affect the driving assist systems, and may cause a system to malfunction.

Maintenance and care
GS450h_300h_OM_OM30F92E_(EE)
Wheels
When replacing wheels, care should be taken to ensure that they are equivalent
to those removed in load capacity, diameter, rim width and inset*.
Replacement wheels are available at any authorized Lexus retailer or Lexus
authorized repairer, or any reliable repairer.
*: Conventionally referred to as “offset”.
Lexus does not recommend using the following:
●Wheels of different sizes or types
●Used wheels
●Bent wheels that have been straightened
●Steel wheels (except for vehicles with steel spare wheel)
●Use only Lexus wheel nuts and wrenches designed for use with your alumi-
num wheels.
●When rotating, repairing or changing your tires, check that the wheel nuts are
still tight after driving 1600 km (1000 miles).
●Be careful not to damage the aluminum wheels when using tire chains.
●Use only Lexus genuine balance weights or equivalent and a plastic or rubber
hammer when balancing your wheels.
■When replacing wheels (vehicles with the tire pressure warning system)
The wheels of your vehicle are equipped with tire pressure warning valves and transmit- ters that allow the tire pressure warning sy stem to provide advance warning in the event of a loss in tire inflation pressure. Whenever wheels are replaced, tire pressure warning
valves and transmitters must be installed. (P. 418)
If a wheel is bent, cracked or heavily corroded, it should be replaced. Other-
wise, the tire may separate from the wheel or cause a loss of handling control.
