1. Adjust the driver's seat, tilt and telescopic steering and
outside rear view mirrors to the desired position.
2. While pushing the ºSETº button, push button º1º or
º2º until the signal beeps.
The beep sound means that the positions are recorded in the
computer 's memory.
By repeating these two steps and pressing the remaining
button, the driving position for another driver can be
recorded.
To set a new memorized position, select the desired position
and perform step 2. The previous memory will be erased and
the new position will be set.
To make only slight changes to an already memorized
position, the easiest way is to first activate the memorized
position, then make the desired changes and perform step 2
above.Activating a memorized position

TRACTION CONTROL SYSTEM
The traction control system automatically helps control
the spinning of the rear wheels which may occur when
accelerating on slippery road surfaces, thus assisting
driver to control the driving power of the rear wheels.
When you turn the ignition switch on, this system always
turns on. Leave the system on during ordinary driving so
that it can operate when needed. When traction control
is applied, the slip indicator blinks.

STARTING AND DRIVING
251
The brake pedal pulsation caused by the anti±lock brake
system may indicate hazardous road surface conditions.
Although the anti±lock brake system assists in providing
vehicle control, it is still important to drive with all due care,
because
the anti±lock brake system cannot overcome the laws
of physics that act on your vehicle:
 Braking capability is dependent on tire friction with the
road surface. 
Even though the anti±lock brake system is operating, a
driver cannot maintain full control on certain slippery road
surfaces, when cornering at high speeds, or in violent
maneuvers.
 Avoid high speeds on wet roads. The anti±lock brake
system cannot eliminate the risk of hydroplaning and loss
of tire friction.
Always maintain a safe distance from the vehicle in front of
you. Compared with vehicles not fitted with 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 on roads where the road surface is pitted or has
other differences in surface height.

DRIVING TIPS
263

The total trailer weight (trailer weight plus its cargo load)
must not exceed 726 kg (1600 lb.). Exceeding this weight is
dangerous.

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.

The gross vehicle weight must not exceed the Gross V ehicle
Weight Rating (GVWR) indicated on the Certification
Label. The gross vehicle weight is the sum weight of the
unloaded vehicle, driver, passengers, luggage, hitch and
trailer tongue load. It also includes the weight of any
special equipment installed on your vehicle.

The load on either the front or rear axle resulting from
distribution of the gross vehicle weight on both axles must
not exceed the Gross Axle Weight Rating (GAWR) listed on
the Certification Label.

DRIVING TIPS

Trailer towing tips
When towing a trailer, your vehicle will handle differ ently
than when not towing. The three main causes of
vehicle±trailer accidents are driver error, excessive speed
and improper trailer loading. Keep these in mind when
towing:

Before starting out, check the operation of the lights and
all vehicle±trailer connections. After driving a short
distance, stop and recheck the lights and connections.
Practice turning, stopping and backing with a trailer in an
area away from traffic until you learn the feel.

Backing with a trailer is difficult and requires practice.
Grip the bottom of the steering wheel and move your hand
to the left to move the trailer to the left. Move your hand
to the right to move the trailer to the right. (This procedure
is generally opposite to that when backing without a
trailer.) Also, just turn the steering wheel a little at a time,
avoiding sharp or prolonged turning. Have someone guide
you when backing to reduce the risk of an accident.

Because stopping distance may be increased,
vehicle±to±vehicle distance should be increased when
towing a trailer. For each 16 km/h (10 mph) of speed,
allow at least one vehicle and trailer length between you
and the vehicle ahead. Avoid sudden braking as you may
skid, resulting in jackknifing and loss of control. This is
especially true on wet or slippery surfaces.

Avoid jerky starts or sudden acceleration.

Avoid jerky steering and sharp turns. The trailer could hit
your vehicle in a tight turn. Slow down before making a
turn to avoid the need of sudden braking.

Remember that when making a turn, the trailer wheels will
be closer than the vehicle wheels to the inside of the turn.
Therefore, compensate for this by making a larger than
normal turning radius with your vehicle.

Crosswinds and rough roads will adversely aff ect handling
of your vehicle and trailer, causing sway. Pay attention to
the rear from time to time to prepare yourself for being
passed by large trucks or buses, which may cause your
vehicle and trailer to sway. If swaying happens, firmly
grip the steering wheel and reduce speed immediately but
gradually. Never increase speed. If it is necessary to
reduce speed, brake slowly. Steer straight ahead. If you
make no extreme correction with the steering or brakes,
your vehicle and trailer will stabilize.

Be careful when passing other vehicles. Passing requires
considerable distance. After passing a vehicle, do not
forget the length of your trailer and be sure you have plenty
of room before changing lanes.

In order to maintain efficient engine braking and electrical
charging performance, do not use overdrive.
Transmission must be in the º4º position (SC400) or in the
º3º position (SC300).

IN CASE OF AN EMERGENCY

IF YOUR VEHICLE NEEDS TOBE TOWED
If towing is necessary, we recommend you to have it done
by your Lexus dealer or a commercial tow truck service.
In consultation with them, have your vehicle towed using
either (a) or (b).
(a) Towing with a wheel lift type truck
(b) Using a flat bed truck
(c) Never tow with a sling type truck
Only when you cannot receive a towing service from a
Lexus dealer or commercial tow truck service, tow your
vehicle car efully in accordance with the instructions given
in º(d) Emergency towingº on page 303.
Proper equipment will help ensure that your vehicle is not
damaged while being towed. Commercial operators are
generally aware of the state/provincial and local laws
pertaining to towing.
Your vehicle can be damaged if it is towed incorrectly.
Although most operators know the correct procedure, it is
possible to make a mistake. To avoid damage to your vehicle,
make sure the following few precautions are observed. If
necessary, show this page to the tow truck driver.
TOWING PRECAUTIONS:
Use a safety chain system for all towing, and abide by the
state/provincial and local laws. The wheels and axle on the ground must be in good condition. If they are damaged, use
a towing dolly.

IN CASE OF AN EMERGENCY
304If towing is necessary, we recommend you to have it done
by your Lexus dealer or a commercial tow truck service.
If towing service is not available in an emergency, your
vehicle may be temporarily towed by a cable or chain
secured to the emergency towing eyelet. Use extreme
caution when towing the vehicle.
A driver must be in the vehicle to steer it and operate the
brakes.
Towing in this manner may be done only on hard±surfaced
roads
for a short distance and at low speeds. Also, the wheels,
axles, drive train, steering and brakes must all be in good
condition.
