CAUTION
■The hill-start assist control may not operate effectively when
●On steep inclines.
●On icy surfaces.
■When the VSC is activated
The slip indicator light flashes and a warning buzzer sounds. Always drive carefully.
Reckless driving may cause an accident. Exercise particular care when the indica-
tor light flashes and a buzzer sounds.
■Replacing tires
Make sure that all tires are of the same size, brand, tread pattern and total load
capacity. In addition, make sure that the ti res are inflated to the specified tire pres-
sure level.
The ABS and VSC will not function correctly if different tires are fitted on the vehi-
cle. 
Contact your Lexus dealer for further info rmation when replacing tires or wheels.
■Handling of tires and suspension
Using tires with any kind of problem or modifying the suspension will affect the
VDIM, and may cause the system to malfunction.

2-5. Driving information
Cargo and luggage
Capacity and distributionCargo capacity depends on the to tal weight of the occupants.
(Cargo capacity) = (Total load capa city) — (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 the driver and passengers that
will be riding in your vehicle.
(3) Subtract the combined weight of the driver and passengers from
XXX kg or XXX lbs.
(4) The resulting figure equals the av ailable amount of cargo and lug-
gage load capacity.
For example, if the “XXX” amount equals 1400 lbs. and there will be
five 150 lb passengers in your vehicl e, the amount 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.
Take notice of the following informat ion about storage precautions, cargo
capacity and load.
● Stow cargo and luggage in the trunk whenever possible. Be sure
all items are secured in place.
● Be careful to keep the vehicle level. Placing the weight as far for-
ward as possible helps maintain vehicle balance.
● For better fuel economy, do not carry unnecessary weight.

When driving
(6) If your vehicle will be towing a trailer, load from your trailer will be transferred to your vehicle. Co nsult this manual to determine how
this reduces the available cargo and luggage load capacity of your
vehicle. ( P. 175)
Example on your vehicle
Cargo capacity
Total load capacity
When 2 people with the combined wei ght of 366 lb. (166 kg) are riding
in your vehicle, which has a total load capacity of 815 lb. (370 kg), the
available amount of cargo and luggag e load capacity will be as follows:
815 lb. — 366 lb. = 449 lb. (370 kg —166 kg = 204 kg)
In this condition, if 3 mo re passengers with the combined weight of 388 lb.
(176 kg) get on, the available cargo and luggage load will be reduced as fol-
lows:
449 lb. — 388 lb. = 61 lb. (204 kg — 176 kg = 28 kg)
As shown in the above example, if the number of occupants increases,
the cargo and luggage load equaling the combined weight of the occu-
pants who got on later, by an amount. In other words, if an increase in the
number of occupants causes an excess of the total load capacity (com-
bined weight of occupants plus car go and luggage load), you must
reduce the cargo and luggage on your vehicle.

CAUTION
■Storage precautions
●Do not place anything on the package tray behind the rear seatback. 
Such items may be thrown about and possib ly injure people in the vehicle during
sudden braking or in an accident.
●Do not drive with objects on top of the instrument panel. 
They may interfere with the driver’s field of view or move during sharp accelera-
tion or turning, thus impairing the driver ’s control of the vehicle. In an accident
they may injure the vehicle occupants.
●Secure all items in the occupant compartment, as they may shift and injure some-
one during an accident or sudden braking.
■Weight of the load
●Improper loading may cause deterioration of steering or braking control result-
ing in an accident which may cause death or serious injury.
●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.

Vehicle load limits
■Total load capacity and seating capacity
These details are also described on the tire and loading information label. 
(  P. 393)
CAUTION
■Overloading the vehicle
Do not overload the vehicle. 
It may not only cause damage to the tire s, but also degrade steering and braking
ability, resulting in an accident.
Vehicle load limits include total load capacity, seating capacity, towing
capacity and cargo capacity.
■ Total load capacity: 815 lb. (370 kg)
Total load capacity means the comb ined weight of occupants, cargo
and luggage.
■ Seating capacity: 5 occupants (Front 2, Rear 3)
Seating capacity means the maximu m number of occupants whose
estimated average weight is 150 lb. (68 kg) per person.
Even if the number of occupants ar e within the seating capacity, do
not exceed the total load capacity.
■ Towing capacity
Lexus does not recommend towing a trailer with your vehicle.
■ Cargo capacity
Cargo capacity ma y increase or decrease depending on the weight
and the number of occupants.

Maintenance and care
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. 3 8 4 )
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
• Lexus wheels with after market chrome plating
■ Aluminum wheel precautions
●Use only Lexus wheel nuts and wr enches 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.

Lubrication system
*: 5W-30 is an oil that provides optimal levels of fuel efficiency.
Oil viscosity:
● The 5W portion of the oil viscosity rating indicates the characteristic of
the oil which allows cold startability . Oils with a lower value before the W
allow for easier starting of the engine in cold weather.
● The 30 in 5W-30 indicates the oil viscosity when the oil is as its operating
temperature. An oil with a higher viscosity may be better suited if the
vehicle is operated at high speeds, or under extreme load condition.
