■Drum-in-disc type parking brake system
Your vehicle has a drum-in-disc type parking brake system. This type of brake system
needs bedding-down of the brake shoes peri odically or whenever the parking brake
shoes and/or drum are replaced. Have your Lexus dealer perform the bedding down
operation.
■Operating your vehicle in a foreign country
Comply with the relevant vehicle registration laws and confirm the availability of the cor-
rect fuel. ( →P. 587)
■Idling time before engine stop (IS200t)
To prevent damage to the turbocharger, allow the engine to idle immediately after high-
load driving.
Driving conditionIdling time
Normal city driving or high-spe ed driving (at the highway speed
limit or recommended speed)
Not necessary
Steep hill driving, continuous driv ing (race track driving etc.), or
towing a trailer or another vehicle (vehicles with towing pack-
age)
Approximately 1 minute

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 trailer 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. 169)
Lexus does not recommend towing a trailer with your vehicle. Your vehicle is not
designed for trailer towing.
