STARTING AND DRIVING
406
Only use tires of specified size. The size,
manufacturer, brand and tread pattern for all 4 tires
should be the same. If you use the tires other than
specified, or different type or size, the vehicle
stability control system may not function correctly.
When replacing the tires or wheels, contact your
Lexus dealer.
In situations where the road surface is covered with
ice or snow, your vehicle should be fitted with snow
tires or tire chains.

Slip indicator light
If the vehicle is going to skid during driving, the slip indicator
light blinks and an alarm sounds intermittently. Special care
should be taken while driving.The slip indicator light comes on for a few seconds when the
ignition key is turned to ONº. If the indicator light does not
come on when the ignition is turned on, contact your Lexus
dealer.
Pushing the center differential lock switch automatically
turns the vehicle stability control system off. At this time,
the VSC OFFº indicator comes on with the center
differential lock indicator light.
VSC OFFº indicator light comes on for a few seconds when
the ignition key is turned to ONº. It will come on again when
you push the center differential lock switch to turn off the
system.
In the following cases, contact your Lexus dealer:
The indicator light does not come on when the ignition key
is turned ONº.
The indicator light remains on after the ignition is turned on.

STARTING AND DRIVING
415
CAUTION
Do not overestimate the anti-lock brake system:
Although the anti-lock brake system assists in
providing vehicle control, it is still important to drive
with all due care and maintain a moderate speed and
safe distance from the vehicle in front of you, because
there are limits to the vehicle stability and effectiveness
of steering wheel operation even with the anti-lock
brake system on.
If tire grip performance exceeds its capability, or if
hydroplaning occurs during high speed driving in the
rain, the anti-lock brake system does not provide
vehicle control.
Anti-lock brake system is not designed to shorten the
stopping distance: Always drive at a moderate speed
and maintain a safe distance from the vehicle in front of
you. Compared with vehicles without an anti-lock
brake system, your vehicle may require a longer
stopping distance in the following cases:
Driving on rough, gravel or snow-covered roads.
Driving with tire chains installed.
Driving over the steps such as the joints on the road.
Driving on roads where the road surface is pitted or
has other differences in surface height.
Install all 4 tires of specified size at appropriate
pressure: The anti-lock brake system detects vehicle
speeds using the speed sensors for respective wheels'
turning speeds. The use of tires other than specified
may fail to detect the accurate turning speed resulting
in a longer stopping distance.

STARTING AND DRIVING
427
LIMITED-SLIP DIFFERENTIAL
Your Lexus is equipped with a limited-slip center differential
(transfer).
If one wheel Ð either front or rear Ð begins to spin, the transfer
(limited-slip center differential) is designed to aid traction by
automatically transmitting driving force to the wheels on the
other drive axle. It transmits driving force to the front wheels
if a rear wheel spins, and to the rear wheels if a front wheel
spins.
CAUTION
Do not start or run the engine while your vehicle is
supported by a jack. The vehicle could be driven off the
jack and could pose a danger or result in serious injury.
NOTICE
Use only a spare tire of the same size, construction and
load capacity as the original tires on your Lexus
because damage to the limited-slip differential could
possibly occur with another tire type.

DRIVING TIPS
446
NOTICE
Do not use axle-mounted hitches as they can cause
damage to the axle housing, wheel bearings, wheels or
tires. Also, never install a hitch which may interfere with
the normal function of an Energy Absorbing Bumper.
Trailer ball
Follow these easy steps to properly determine the correct
trailer ball for your application:
1. Determine the correct trailer ball size for the trailer coupler.
Most couplers are stamped with the required trailer ball size.
The sizes you'll most likely find stamped on the coupler are:
Trailer Class
Typical Trailer Ball Size
III 2 in.
II 2 in.
I 1 7/8 in.
2. Select the appropriate trailer ball to match or exceed the
gross trailer weight rating of the trailer. The trailer ball load
rating should be printed on the top of the ball.

Towing capacity:
For weight carrying hitch 2268 kg (5000 lb.)
Also for weight distributing hitch
2948 kg (6500 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 distributionº 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.
CARGO AND LUGGAGE
Stowage precautions
When stowing cargo and luggage in the vehicle,
observe the following:
Put cargo and luggage in the luggage compartment
when at all possible. Be sure all items are secured
in place.
Be careful to keep the vehicle level. Placing the
weight as far forward as possible helps maintain
vehicle balance.
For better fuel economy, do not carry unnecessary
weight.
CAUTION
To prevent cargo and luggage from sliding
forward during braking, do not stack anything
in the luggage compartment higher than the
seatbacks. Keep luggage or packages low,
as close to the floor as possible.

CHECKING TIRE INFLATION
PRESSURE
63PY020
The recommended cold tire inflation pressures,
tire sizes and the combined weight of occupants
and cargo (vehicle capacity weight) are described
on page 553 and 606. 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.
If you cannot adjust the tire pressure when the
tires are cold, add 20 to 30 kPa more to the front
tires and rear tires than the cold tire pressure, but
never exceed the maximum cold tire pressure
molded on the tire sidewall.
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.
