Driving
RC350_RC300 AWD_RC3 00_RC F_U(OM24748U)Cargo capacity depends on the total weight of the occupants.
(Cargo capacity) = (Total load capac ity) — (Total weight of occupants)
Steps for Determining Correct Load Limit —
(1) Locate the statement “The combined weight of occupants and cargo should
never exceed XXX kg or XXX lbs. ” on your vehicle’s placard.
(2) Determine the combined weight of th e driver and passengers that will be rid-
ing in your vehicle.
(3) Subtract the combined weight of th e driver and passengers from XXX kg or
XXX lbs.
(4) The resulting figure equals the ava ilable amount of cargo and luggage load
capacity.
For example, if the “XXX” amount equals 1400 lbs. and there will be five 150
lb passengers in your vehicle, the amou nt of available cargo and luggage load
capacity is 650 lbs. (1400  750 (5  150) = 650 lbs.)
(5) Determine the combined weight of luggage and cargo being loaded on the
vehicle. That weight may not safely exceed the available cargo and luggage
load capacity calculated in Step 4.
(6) If your vehicle will be towing a trailer, load from your tra iler will be transferred
to your vehicle. Consult this manual to determine how this reduces the avail-
able cargo and luggage load capacity of your vehicle.
(  P. 204)Lexus does not recommend towing a trailer with your vehicle. Your vehicle is not
designed for trailer towing.Cargo and luggage Take notice of the following informat ion about storage precautions, cargo

Total load capacity (vehicle capacity
weight) (  P. 536)
When 2 people with the combined weight of A lb. (kg) are riding in your vehicle,
which has a total load capacity (vehicle capacity weight) of B lb. (kg), the avail-
able amount of cargo and luggage load capacity will be C lb. (kg) as follows:
B
* 2
lb. (kg) - A
* 1
lb. (kg) = C
* 3
lb. (kg)
* 1
: A =Weight of people
* 2
: B =Total load capacity
* 3
: C =Available cargo and luggage load In this condition, if 2 more passengers with the combined weight of D lb. (kg) get on,
the available cargo and luggage load w ill be reduced E lb. (kg) as follows:
C lb. (kg) - D
* 4
lb. (kg) = E
* 5
lb. (kg)
* 4
: D =Additional weight of people
* 5
: E =Available cargo and luggage load
As shown in the example above, if the nu mber of occupants increases, the cargo
and luggage load will be reduced by an amount that equals the increased weight
due to the additional occupants. In other words, if an increa se in the number of
occupants causes an excess of the total load capacity (combined weight of occu-
pants plus cargo and luggage load), yo u must reduce the cargo and luggage on
your vehicle. Calculation formula for your vehicle 1

RC350_RC300 AWD_RC3 00_RC F_U(OM24748U)WARNING ■
Things that must not be carried in the trunk
The following things may cause a fire if loaded in the trunk: ●
Receptacles containing gasoline ●
Aerosol cans ■
Storage precautions
Observe the following precautions.
Failure to do so may prevent the pedals from being depressed properly, may block the
driver’s vision, or may result in items hittin g the driver or passeng ers, possibly causing
an accident. ●
Stow cargo and lugg age in the trunk whenever possible.●
RC350/RC300: To prevent cargo and luggage from sliding forward during braking,
do not stack anything in the enlarged trun k. Keep cargo and luggage low, as close to
the floor as possible. ●
RC350/RC300: When you fold down the rear seats, long items should not be
placed directly behind the front seats. ●
RC350/RC300: Never allow anyone to ride in the enlarged trunk. It is not designed
for passengers. They should ride in their se ats with their seat belts properly fastened.●
Do not place cargo or luggage in or on the following locations.
• At the feet of the driver
• On the front passenger or re ar seats (when stacking items)
• On the package tray
• On the instrument panel
•On the dashboard
• In front of the Center Display ●
Secure all items in the occupant compartment. ■
Capacity and distribution ●
Do not exceed the maximum axle weight rating 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 deterioration
of steering or braking control whic h may cause death or serious injury.

When the TRAC/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 stab ility and driving force, do not turn the
TRAC/VSC systems off unless necessary. ■
Expert mode precautions ●
Do not use on public roads. ●
Use only when the road co nditions and safety of the surrounding area can be
ensured. ●
Proper use of expert mode requires a professional level of driving skill. When using
expert mode, always check the road condit ions and surrounding area and drive more
carefully than usual. ■
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 tire s are inflated to the recommended tire infla-
tion pressure level.
The ABS, TRAC and VSC systems will not function correctly if different tires are
installed on the vehicle.
Contact your Lexus dealer for further in formation when replacing tires or wheels.■
Handling of tires and the suspension
Using tires with any kind of problem or modi fying the suspension w ill affect the driving

Tire types ●
Summer tires
Summer tires are high-speed performance ti res best suited to highway driving under
dry conditions. Since summer tires do not have the same traction performance as
snow tires, summer tires are inadequate for driving on snow-covered or icy roads. For
driving on snow-covered roads or icy road s, the use of snow tires is recommended.
When installing snow tires, be sure to replace all four tires.●
All season tires
All season tires are designed to provide better traction in snow and to be adequate for
driving in most winter conditions as well as for use year-round. All season tires, how-
ever, do not have adequate traction perfor mance compared with snow tires in heavy
or loose snow. Also, all season tires fall short in acceleration and handling perfor-
mance compared with summer tires in highway driving.●
Snow tires
For driving on snow-covered roads or icy roads, we recommend using snow tires. If
you need snow tires, select ti res of the same size, construction and load capacity as the
originally installed tires. Since your vehicle has radial tires as or iginal equipment, make
sure your snow tires also have radial cons truction. Do not install studded tires without
first checking local regulations for possible restrictions. Snow tires should be installed
on all wheels. (  P. 320)■
If the tread on snow tires wears down below 0.16 in. (4 mm)
The effectiveness of the tire s as snow tires is lost.For the GAWR, see the Ce rtification Label. For
the maximum load of the tire, see the load limit
at maximum cold tire inflation pressure men-
tioned on the sidewall of the tire. (  P. 557)

Maintenance and care When replacing wheels, care should be ta ken to ensure that they are equivalent
to those removed in load capacity, diameter, rim width and inset
* .
Replacement wheels are available at your Lexus dealer.
* : 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 ●
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 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. ■
When replacing wheels
The wheels of your vehicle are equipped with tire pressure warning valves and transmit-
ters that allow the tire pressure warning system 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. 413)Wheels 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.
