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.

MAINTENANCE
532
Tire inflation pressure
Check the pressure with a gauge every two weeks,
or at least once a month and adjust as shown on the
tire and loading information label. See page 570 for
additional information.
Tire surface
Check the tires carefully for cuts, damage or
excessive wear. See page 585 for additional
information.
Tire rotation
Rotate the tires according to the maintenance
schedule. (For scheduled maintenance information,
please refer to the “Owner’s Manual Supplement /
Scheduled Maintenance”.) See “Rotating tires” on
page 584.DOES YOUR VEHICLE NEEDREPAIRING?
Be on the alert for changes in performance and sounds, and
visual tip −offs that indicate service is needed. Some important
clues are:
 Engine missing, stumbling, or pinging
 Appreciable loss of power
 Strange engine noises
 A fluid leak under the vehicle (However, water dripping from
the air conditioning after use is normal.)
 Change in exhaust sound (This may indicate a dangerous
carbon monoxide leak. Drive with the windows open and
have the exhaust system checked immediately.)
 Flat−looking tires, excessive tire squeal when cornering,
uneven tire wear
 Vehicle pulls to one side when driving straight on a level
road
 Strange noises related to suspension movement
 Loss of brake effectiveness, spongy feeling brake pedal,
pedal almost touches floors, vehicle pulls to one side when
braking
 Engine coolant temperature continually higher than normal
If you notice any of these clues, take your vehicle to your Lexus
dealer as soon as possible. It probably needs adjustment or
repair.

CHECKING TIRE INFLATIONPRESSURE

CHASSIS
571
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.

CHASSIS
572
4. In case the tire inflation pressure is not within the
prescribed range, insert the compressed air from the
valve. In case of applying too much air, press the
center of the valve and release the air to adjust.
5. After completing the tire inflation pressure
measurement and adjustment, apply soapy water to
the valve and check for leakage.
6. Install the tire valve cap.
If a gauge and air pump are not available, have your
vehicle checked by your Lexus dealer.
CAUTION
Be sure to reinstall the tire valve caps. Without
the valve caps, dirt or moisture could get into
the valve core and cause air leakage. If the caps
have been lost, have new ones put on as soon
as possible.
Incorrect tire inflation pressure may waste fuel, reduce
the comfort of driving, reduce tire life and make your
vehicle less safe to drive.
If a tire frequently needs refilling, have it checked by
your Lexus dealer.
CAUTION
Keep your tires properly inflated. Otherwise, the
following conditions may occur and cause an
accident resulting in death or serious injuries.
Low tire pressure (underinflation) —
Excessive wear
 Uneven wear
 Poor handling
 Possibility of blowouts from an overheated
tire
 Poor sealing of the tire bead
 Wheel deformation and/or tire separation
 A greater possibility of tire damage from road
hazards
High tire pressure (overinflation) —
 Poor handling
 Excessive wear
 Uneven wear
 A greater possibility of tire damage from road
hazards
