Before driving
Turn the upper knobs clockwise to
fix the cross rails to the appropri-
ate length.STEP3
CAUTION
■Cross rail adjustment
Make sure the cross rails are locked securely by pushing forward and rearward
them.
Failure to do so may cause an unexpected accident or severe injury in the event of
emergency braking or a collision.
■When loading cargo
Observe the following precautions.
●Place the cargo so that its weight is distributed evenly between the front and rear
axles.
●If loading long or wide cargo, never exceed the vehicle overall length or
width.(
P. 3 6 8 )
●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 the vehicle
gravity higher. Avoid high speeds, sudden starts, sharp turns, sudden braking or
abrupt maneuvers, otherwise it may result in loss of control or vehicle rollover
due to failure to operate this vehicle correctly.
●If driving for a long distance, on rough ro ads, or at high speeds, stop the vehicle
now and then during the trip to make sure the cargo remains in its place.
●Do not exceed 143 lb. (70 kg) cargo weight on the roof luggage carrier.

Wheels
■When replacing wheels
The wheels of your Lexus are equipped with tire pressure warning valves and trans-
mitters that allow the tire pressure warning system to provide advanced warning in
the event of a loss in tire inflation pressure. Whenever wheels are replaced, the tire
pressure warning valves and transmitters must be switched over from the old
wheels. ( P. 2 9 3 )
If a wheel is bent, cracked or heavily corroded, it should be replaced.
Otherwise, the tire may separate from the wheel or cause loss of handling
control.
■ Wheel selection
When replacing wheels, care should be taken to ensure that they
are equivalent to those removed in load capacity, diameter, rim
width, and offset.
Replacement wheels are available at your Lexus dealer.
Lexus does not recommend using:
• 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.
