When driving CAUTION●
Never allow anyone to ride in the luggage compartment. It is not designed for
passengers. They should ride in their seat s with their seat belt s properly fastened.
Otherwise, they are much more likely to suffer death or serious bodily injury, in
the event of sudden braking, sudden swerving or an accident.■
Capacity and distribution ●
Do not exceed the maximum axle weight ra ting or the total vehicle weight rating. ●
Even if the total load of occupant's weight and the cargo load is less than the total
load capacity, do not apply the load unevenly. Improper loading may cause dete-
rioration of steering or braking control which may cause death or serious injury.■
Roof luggage carrier precautions (if equipped)
To use the roof rails as a roof luggage carrier, you must fit the roof rails with two or
more genuine Lexus cross rails or their equivalent.
When you load cargo on the roof luggage carrier, observe the following:
●
Before driving, make sure the cargo is securely fastened on the roof luggage car-
rier.●
Loading cargo on the roof luggage carrier will make the center of gravity of the
vehicle higher. Avoid high speeds, sudden starts, sharp turns, sudden braking or
abrupt maneuvers, otherwise the result may be a loss of control or vehicle roll-
over due to failure to operate this vehicl e correctly and result in death or serious
injury.
●
If driving for long distances, on rough ro ads, or at high spee ds, stop the vehicle
now and then during the trip to make sure the cargo remains in its place.
●
Do not exceed 165 lb. (75 kg) cargo weight on the roof luggage carrier.
●
To reduce wind noise when there is no luggage loaded on the roof luggage car-
rier, move the front cross rail to the front-most position and the rear cross rail to
the rearmost position. ●
Place the cargo so that its weight is distrib-
uted evenly between the front and rear
axles. ●
If loading long or wide cargo, never exceed
the vehicle’s overall length or width.

When driving
Selecting tire chains
Use the correct tire chain size when mounting the tire chains. Chain size
is regulated for each tire size.
Side chain:
0.12 in. (3 mm) in diameter
0.98 in. (25 mm) in length
0.43 in. (10.8 mm) in width
Cross chain:
0.15 in. (3.9 mm) in diameter
1.00 in. (25.3 mm) in length
0.54 in. (13.8 mm) in width
Regulations on the use of tire chains
Regulations regarding the use of tire chains vary depending on location
and type of road. Always check local regulations before installing chains. ■ When driving the vehicle
Accelerate the vehicle slowly, keep a safe distance between you and
the vehicle ahead, and drive at a reduced speed suitable to road
conditions.
■ When parking the vehicle
Park the vehicle and move the shif t lever to P without setting the
parking brake. The parking brake may freeze up, preventing it from
being released. If necessary, bl ock the wheels to prevent inadvert-
ent sliding or creeping.

Maintenance and care Wheels
■
When replacing wheels
The wheels of your vehicle are equipped with tire pressure warning valves and
transmitters that allow the tire pressure warning system to provide advanced warn-
ing in the event of a loss in tire inflation pressure. Whenever wheels are replaced,
tire pressure warning valves and transmitters must be installed. (  P. 6 8 5 )If a wheel is bent, cracked or heavily corroded, it should be replaced.
Otherwise, the tire may separate from the wheel or cause a loss of han-
dling control.
■ Wheel selection
When replacing wheels, care should be taken to ensure that they
are equivalent to those removed in load capaci ty, diameter, rim
width, and inset*.
Replacement wheels are available at your Lexus dealer. *: Conventionally referred to as “offset”.
Lexus does not recommen d using the following:
● Wheels of different sizes or types
● Used wheels
● Bent wheels that have been straightened
■ Aluminum wheel precautions
● Use only Lexus wheel nuts and wrenches designed for use with
your aluminum wheels.
● When rotating, repairing or changi ng your tires, check that the
wheel nuts are still tight after driving 1000 miles (1600 km).
● 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.
