For the first 200 miles (300 km):
Avoid sudden stops. ●
For the first 500 miles (800 km):
Do not tow a trailer. ●
For the first 1000 miles (1600 km):
• Do not drive at extremely high speeds.
• Avoid sudden acceleration.
• Do not drive continuously in low gears.
• Do not drive at a constant speed for extended periods.■
Operating your vehicle in a foreign country
Comply with the relevant vehicle registration laws and confirm the availability of the cor-
rect fuel. ( → P. 712)■
Eco-friendly driving
→ P. 121
WARNING
Observe the following precautions.
Failure to do so may result in death or serious injury. ■
When starting the vehicle
Always keep your foot on the brake pedal while stopped with the “READY” indicator is
illuminated. This prevents the vehicle from creeping.■
When driving the vehicle ●
Do not drive if you are unfamiliar with the location of the brake and accelerator ped-
als to avoid depressing the wrong pedal.
• Accidentally depressing the accelerator pedal instead of the brake pedal will
result in sudden acceleration that may lead to an accident.
• When backing up, you may twist your body around, leading to difficulty in operat-
ing the pedals. Make sure to operate the pedals properly.
• Make sure to keep a correct driving po sture even when moving the vehicle only
slightly. This allows you to depress th e brake and accelerator pedals properly.
• Depress the brake pedal using your right foot. Depressing the brake pedal using
your left foot may delay re sponse in an emergency, resulting in an accident.●
The driver should pay extra attention to pedestrians when the vehicle is powered only
by the electric motor (traction motor). As there is no engine noise, the pedestrians
may misjudge the vehicle’s movement. ●
Do not drive the vehicle over or stop the vehicle near flammable materials.
The exhaust system and exhaust gases can be extremely hot. These hot parts may
cause a fire if there is any flammable material nearby.

220 4-1. Before driving
RX450h_RX450hL _U_OM48F85UCargo 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. 223) Vehicles without towing package: 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
capacity and load.

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 luggage in the luggage compartment whenever possible.●
Do not stack cargo and luggage in the luggage compartment higher than the seat-
backs. ●
When you fold down the rear seats, long items should not be placed directly behind
the front seats. ●
Never allow anyone to ride in the luggage compartment. It is not designed for pas-
sengers. They should ride in their seats with their se at 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 luggage cover
• On the instrument panel
•On the dashboard ●
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.■
Roof luggage carrier precautions
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. 710) ●
Before driving, make sure the cargo is secu rely fastened on the roof luggage carrier.●
Loading cargo on the roof luggage carrier will make the center of gravity of the vehi-
cle higher. Avoid high speeds, sudden star ts, sharp turns, sudden braking or abrupt
maneuvers, otherwise it may re sult in loss of control or vehicle rollover due to failure
to operate this vehicle correctly and result in death or serious injury.●
If driving for a long distance, on rough road s, 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 165 lb. (75 kg) cargo weight on the roof luggage carrier.
