STARTING AND DRIVING

Brake assist system
If you slam the brakes on such as in an emergency or
apply the brakes more firmly than usual such as when
descending the hill with the designated number of
occupants in the vehicle, the brake assist system
provides more powerful braking.
If you slam the brakes on or apply the brakes more firmly, more
powerful braking will be applied. At this time, you may hear a
sound in the engine compartment and feel the vibrations of the
brake pedal. This does not indicate a malfunction.
The brake assist system becomes operative after the vehicle
has accelerated to a speed in excess of approximately 10 km/h
(6 mph). It stops operating when the vehicle decelerates to a
speed below approximately 5 km/h (3 mph).
For an explanation of this system’s warning light, see “ABS
warning light” on page 81 or 460.
TIRE PRESSURE WARNING SYSTEM
The tire pressure warning system is designed to provide
warning when tire inflation pressure is critically low while
the vehicle is moving. The low tire pressure warning light
comes on to inform you that such low tire pressure may
hamper driving.
This system is not designed to operate when the vehicle is
stopped. Therefore, check the tire inflation pressure regularly.
The recommended cold tire inflation pressure, tire size and the
vehicle capacity weight are on the tire and loading information
label. (For instructions, see “Checking tire inflation pressure”
on page 570.)
Installed tires should be of the specified size. They should be
of the same size and construction. If tires other than the
specified size are used, or if tires of different sizes or
constructions are mixed, the tire pressure warning system will
not function properly.

DRIVING TIPS

Weight limits
Before towing, make sure the total trailer weight, gross
vehicle weight, gross axle weight and trailer tongue load
are all within the limits.
The total trailer weight and tongue load can be measured with
platform scales found at a highway weighing station, building
supply company, trucking company, junk yard, etc.
Certification label
CAUTION
The total trailer weight (trailer weight plus its cargo
load) must not exceed the following. Exceeding this
weight is dangerous. Without towing package 907 kg (2000 lb.)
With towing package 1588 kg (3500 lb.)
 If towing a trailer and cargo weighing over 907 kg
(2000 lb.), Lexus recommends to use a sway control
device with sufficient capacity. The gross
combination weight (sum of your vehicle weight plus
its load and the total trailer weight) must not exceed
the following. Without towing package 3286 kg (7245 lb.)
With towing package 3966 kg (8745 lb.)
 Trailer hitch assemblies have different weight
capacities established by the hitch manufacturer.
Even though the vehicle may be physically capable of
towing a higher weight, the operator must determine
the maximum weight rating of the particular hitch
assembly and never exceed the maximum weight
rating specified for the trailer hitch. Exceeding the
maximum weight rating set by the trailer hitch
manufacturer can cause an accident resulting in
serious personal injuries.

VEHICLE LOAD LIMITS
Vehicle load limits include total load capacity, seating
capacity, towing capacity and cargo capacity. Follow
the load limits shown below. Total load capacity and
seating capacity are also described on the tire and
loading information label. For location of the tire and
loading information label, see “Checking tire inflation
pressure” on page 570.
Total load capacity: 420 kg (925 lb.)
Total load capacity means combined weight of
occupants, cargo and luggage. Tongue load is
included when trailer towing.
Seating capacity: Total 5 (Front 2, Rear 3)
Seating capacity means the maximum number of
occupants whose estimated average weight is 68 kg
(150 lb.) per person. Depending on the weight of
each person, the seating capacity given may exceed
the total load capacity.
NOTICE
Even if the number of occupants are within the
seating capacity, do not exceed the total load
capacity.
Towing capacity:
Without towing package 907 kg (2000 lb.)
With towing package 1588 kg (3500 lb.)
Towing capacity 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 decrease depending
on the size (weight) and the number of occupants.
For details, see “Capacity and distribution” that
follows.
CAUTION
Do not apply the load more than each load limit.
That may cause not only damage to the tires,
but also deterioration to the steering ability and
braking ability, which may cause an accident.

DRIVING TIPS
491
Capacity and distribution
Cargo capacity depends on the total 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
pounds” 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 kilograms or XXX pounds.
4. The resulting figure equals the available 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 amount of
available cargo and luggage load capacity is 650 lbs.
1400 – 750 (5 x 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 available
cargo and luggage load capacity of your vehicle.
For details about trailer towing, see page 476.

Example on your vehicle
1Cargo capacity
2Total load capacity
In case that 2 people with the combined weight of
166 kg (366 lb.) are riding in your vehicle with the
total load capacity of 420 kg (925 lb.), the available
amount of cargo and luggage load capacity will be
as follows:
420 kg – 166 kg = 254 kg.
(925 lb. – 366 lb. = 559 lb.)
From this condition, if 3 more passengers with the
combined weight of 176 kg (388 lb.) get on, the
available cargo and luggage load will be reduced as
follows:
254 kg – 176 kg = 78 kg.
(559 lb. – 388 lb. = 171 lb.) As shown in the above example, if the number of
occupants increases, the cargo and luggage load
equaling the combined weight of occupants who got
on later must be reduced. In other words, if the
increase in the number of occupants causes the
excess of the total load capacity (combined weight
of occupants plus cargo and luggage load), you have
to reduce the cargo and luggage on your vehicle.
For details about total load capacity, see “Vehicle load
limits” on page 489.
CAUTION
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. That
may cause not only damage to the tire but also
deterioration to the steering ability due to
unbalance of the vehicle, causing an accident.

CHASSIS

The recommended cold tire inflation pressures,
tire sizes and the combined weight of occupants
and cargo (vehicle capacity weight) are described
on pages 566 and 616. They are also described
on the tire and loading information label as
shown.
You should check the tire inflation pressure every two
weeks, or at least once a month. And do not forget
the spare!
The following instructions for checking tire
inflation pressure should be observed:
The pressure should be checked only when the
tires are cold. If your vehicle has been parked
for at least 3 hours and has not been driven for
more than 1.5 km or 1 mile since, you will get an
accurate cold tire inflation pressure reading.
 Always use a tire pressure gauge. The
appearance of a tire can be misleading. Besides,
tire inflation pressures that are even just a few
pounds off can degrade handling and ride.
 Do not bleed or reduce tire inflation pressure
after driving. It is normal for the tire inflation
pressure to be higher after driving. 
Never exceed the vehicle capacity weight.
Passengers and luggage weight should be located
so that the vehicle is balanced.
Inspection and adjustment procedure
1Tire valve
2Tire pressure gauge
1. Remove the tire valve cap.
2. Press the tip of the tire pressure gauge to the tire
valve.
3. Read the pressure using the graduations of the
gauge.
