Driving
■When starting off on a uphill (vehicles with hill-start assist control system)
The hill-start assist control is available. ( P. 3 4 6 )
■Driving in the rain
●Drive carefully when it is raining, because visibility will be reduced, the windows may
become fogged-up, and th e road will be slippery.
●Drive carefully when it starts to rain, becau se the road surface will be especially slip-
pery.
●Refrain from high speeds when driving on an expressway in the rain, because there may
be a layer of water between the tires and the road surface, preventing the steering and
brakes from operating properly.
■Engine speed while driving
In the following conditions, the engine speed may become high while driving. This is due
to automatic up-shifting control or down-shi fting implementation to meet driving condi-
tions. It does not indica te sudden acceleration.
●The vehicle is judged to be driving uphill or downhill
●When the accelerator pedal is released
■Breaking in your new Lexus
To extend the life of the ve hicle, observing the followin g precautions is recommended:
●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 600 miles (1000 km):
• Do not drive at extremely high speeds.
• Avoid sudden acceleration.
• Do not drive continuously in the low gears.
• Do not drive at a constant speed for extended periods.
■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 periodically or when-
ever 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 vehi cle registration laws and confirm the availability of the cor-
rect fuel. ( P. 5 6 4 )
■When turning off the engine
Emission system operating sounds may cont inue for a short time after the engine is
turned off. This is not a malfunction, and helps to ensure optimal performance of the
emission system.

Cargo and luggage
Cargo capacity depends on the to
tal weight of the occupants.
(Cargo capacity) = (Total load capacity)  (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 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 am ount 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. 1 6 5 )
Take notice of the following information about storage precautions, cargo
capacity and load:

Vehicle load limits
◆Total load capacity (vehicle capacity weight):
P. 5 6 2
Total load capacity means the combined weight of occupants, cargo and lug-
gage.
◆Seating capacity: 7 occupants (Front 2, Rear 5)
Seating capacity means the maximum number of occupants whose estimated
average weight is 150 lb. (68 kg) per person.
◆TWR (Trailer Weight Rating): P. 1 7 0 , 5 6 2
TWR means the maximum gross trailer weight (trailer weight plus its cargo
weight) that your vehicle is able to tow.
◆Cargo capacity
Cargo capacity may increase or decrea se depending on the weight and the
number of occupants.
■Total load capacity and seating capacity
These details are also described on the tire and loading information label. (P. 4 7 5 )
Vehicle load limits include total load capacity, seating capacity, TWR (Trailer
Weight Rating) and cargo capacity.
CAUTION
■Overloading the vehicle
Do not overload the vehicle.
It may not only cause damage to the tires, but also degrade steering and braking ability,
resulting in an accident.

Trailer towing (with towing hitch)
Contact your Lexus dealer for further in
formation about additional requirements
such as towing kits, etc.
Your vehicle is designed primarily as a passenger-and-load-carrying vehicle.
Towing a trailer can have an adverse impact on handling, performance, brak-
ing, durability, and fuel consumption. Fo r your safety and the safety of others,
you must not overload your vehicle or trailer. You must also ensure that you
are using appropriate towing equipment, that the towing equipment has been
installed correctly and used properly, and that you employ the requisite driv-
ing habits.
Vehicle-trailer stability and braking pe rformance are affected by trailer sta-
bility, brake performance and setting, tr ailer brakes, the hitch and hitch sys-
tems (if equipped).
To tow a trailer safely, use extreme ca re and drive the vehicle in accordance
with your trailer’s characteristics and operating conditions.
Lexus warranties do not apply to damage or malfunction caused by towing a
trailer for commer cial purposes.

■GCWR (Gross Combination Weight Rating)
The maximum allowable gross com-
bination weight. The gross combina-
tion weight is the sum of the total
vehicle weight (including the occu-
pants, cargo and any optional equip-
ment installed on the vehicle) and
the weight of the trailer being towed
(including the cargo in the trailer).
■GVWR (Gross Vehicle Weight Rating)
The maximum allowable gross vehi-
cle weight. The gross vehicle weight
is the total weight of the vehicle.
When towing a trailer, it is the sum of
the vehicle weight (including the
occupants, cargo and any optional
equipment installed on the vehicle)
and the tongue weight.

■GAWR (Gross Axle Weight Rating)
The maximum allowable gross axle
weight. The gross axle weight is the
load placed on each axle (front and
rear).
■TWR (Trailer Weight Rating)
The maximum allowable gross trailer
weight. The gross trailer weight is
the sum of the trailer weight and the
weight of the cargo in the trailer.
TWR is calculated assuming base
vehicle with one driver, one front
passenger, towing package (if avail-
able), hitch and hitch systems (if
required).
Additional optional equipment, passengers
and cargo in the vehicle will reduce the
trailer weight rating so as not to exceed GCWR, GVWR and GAWR.
If the gross trailer weight exceeds 3000 lb. (1360 kg), it is recommended to use a
trailer with 2 or more axles.

●A recommended tongue weight varies in accordance with the types of trailers
or towing as described below.
●To ensure the recommended values shown below, the trailer must be loaded
by referring to the following instructions. •Tongue Weight
The gross trailer weight should be dist ributed so that the tongue weight is
9 % to 11 %. (Tongue weight/Gross trailer weight  100 = 9 % to 11 %)

Tongue weight
If using a weight distributing hitch when towing, return the front axle to the
same weight as before the trailer connection.
If front axle weight cannot be measured directly, measure the front fender
height above the front axle before co nnection. Adjust weight distributing
hitch torque until front fender is return ed to the same height as before con-
nection.
The gross trailer weight, gross axle we ight and tongue weight can be mea-
sured with platform scales found at a highway weighing station, building
supply company, trucking company, junk yard, etc.
