(a) Brake System Warning Light
This light has the following two functions:
Parking brake reminder
If this light is on, make sure the parking brake is fully released. The\
light
should go off.
Low brake fluid level warning
If this light comes on and stays on while you are driving, slow down and p\
ull
off the road. Then stop the vehicle carefully. Remember that stopping
distance and pedal effort may be increased. There may be a problem
somewhere in the brake system. Check the fluid level of the see±through
reservoir.
To make sure the parking brake has not caused the warning light to come on\
,
check to see that the parking brake is fully released.
If the brake fluid level is low ...
At a safe place, test your brakes by starting and stopping.
 If you judge that the brakes still work adequately, drive cautiously to your
nearest dealer or shop for repairs.
 If the brakes are not working, have the vehicle towed in for repairs. (\
For
towing information, see page 173.)
CAUTION
It is dangerous to continue driving normally when the brake
fluid level is low.

STARTING AND DRIVING147
TRACTION CONTROL SYSTEM
The traction control system automatically helps control the spinning of
the front wheels which may occur when accelerating on slippery road
surfaces, thus assisting driver to control the driving power of the front
wheels.
31E013
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 light blinks.
31E014±1
You can turn off the traction control system by pushing the ºTRAC OFFº
switch. The ºTRAC OFFº indicator/warning light will then come on. Pushing
the ºTRAC OFFº switch a second time turns the system back on
and extinguishes the ºTRAC OFFº indicator/warning light.
When the traction control system is operating, you may feel vibration or nois\
e
of your vehicle, caused by operation of the brakes. This indicates the sy\
stem
is functioning properly.
When getting the vehicle out of mud or new snow, etc. the traction control
system will help operate to prevent the wheels from spinning.
Traction control failure warning
If the ºTRAC OFFº indicator/warning light flashes, contact your Lexus dealer
as soon as possible. There may be trouble in the traction control syste\
m.
CAUTION
Under certain slippery road conditions, full traction of the
vehicle and power to the front wheels cannot be maintained,
even though the traction control system is in operation. Do not
drive the vehicle under any speed or maneuvering conditions
which will cause the vehicle to lose traction. In situations
where the road surface is covered with ice or snow, your
vehicle should be fitted with snow tires or tire chains. Always
drive at an appropriate and cautious pace.

STARTING AND DRIVING
148
BRAKE SYSTEM
The tandem master cylinder brake system is a hydraulic system with two
separate sub±systems. If either sub±system should fail, the other will still
work. However, the pedal will be harder to press, and your stopping distance
will be longer. Also, the brake system warning light may come on.
CAUTION
Do not drive your vehicle with only a single brake system.
Have your brakes fixed immediately.
Brake booster
The brake booster uses engine vacuum to power±assist the brakes. If the
engine should quit while you are driving, you can bring the vehicle to a stop
with normal pedal pressure. There is enough reserve vacuum for one or t\
wo
stops but no more!
CAUTION
Do not pump the brake pedal if the engine stalls. Each push
on the pedal uses up your vacuum reserve.
 Even if the power assist is completely lost, the brakes will
still work. But you will have to push the pedal hard ± much
harder than normal. And your braking distance will be
longer.
Anti±lock brake system
The anti±lock brake system is designed to automatically help prevent
lock±up of the wheels during a sudden brake or braking on slippery road
surfaces. This assists in providing directional stability and steering
performance of the vehicle under these circumstances.
The anti±lock brake 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).
You may hear a sound in the engine compartment for a few seconds when the
engine is started or just after the vehicle is started. This means that the
anti±lock brake system is in the self±check mode, and does not indicate a
malfunction.
Effective way to press the ABS brake pedal: When the anti±lock brake
system function is in action, you may feel the brake pedal pulsating and hear
a noise. In this situation, to let the anti±lock brake system work f\
or you, just
hold the brake pedal down more firmly. Do not pump the brake. This will
result in reduced braking performance.
The brake pedal pulsation caused by the anti±lock brake system may indic\
ate
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 physic\
s
that act on your vehicle:
 Braking capability is dependent on tire friction with the road surface.

BRAKE PAD WEAR LIMIT INDICATORS
31E016
The brake pad wear limit indicators on your disc brakes give a warning
noise when the brake pads are worn to the extent that replacement is
required.
If you hear a squealing or scraping noise while driving, have the brake \
pads
checked and replaced by your Lexus dealer as soon as possible. Expensive
rotor damage can result if the pads are not replaced when needed.
TYPES OF TIRES
Determine what kind of tires your vehicle is originally equipped with.
1. Summer tires
Summer tires are high±speed capability tires best suited to highway driving\
under dry conditions.
Since summer tires do not have the same traction performance as snow tires,
summer tires are inadequate for driving on snow±covered or icy roads. For
driving on snow±covered or icy roads, we recommend using snow tires. If
installing snow tires, be sure to replace all four tires.
2. All season tires
All season tires are designed to provide better traction in snow and to \
be
adequate for driving in most winter conditions, as well as for use all year
round.
All season tires, however, do not have adequate traction performance
compared with snow tires in heavy or loose snow. Also, all season tires fall
short in acceleration and handling performance compared with summer tires
in highway driving.
CAUTION
Do not mix summer and all season tires on your vehicle as
this can cause dangerous handling characteristics,
resulting in loss of control.
 Do not use tires other than the manufacturer's designated
tires, and never mix tires or wheels of the sizes different
from the originals.

DRIVING TIPS
152
BREAK±IN PERIOD
Drive gently and avoid high speeds.
You need not follow a break±in schedule with your new Lexus. But follow\
ing
a few simple tips for the first 1600 km (1000 miles) can add to the fu\
ture
economy and long life of your vehicle:
Do not drive over 88 km/h (55 mph).
 Avoid overrevving. Maintain engine speed between 2000 and 4000 rpm.
 Avoid full±throttle starts.
 Try to avoid hard stops during the first 300 km (200 miles).
 Do not drive for a long time at any single speed, either fast or slow.
 Do not tow a trailer during the first 800 km (500 miles).
OPERATION IN FOREIGN COUNTRIES
If you plan to drive your Lexus in another country ...
First, comply with the vehicle registration laws.
Second, confirm the availability of the correct fuel (unleaded and minimum
octane rating).
TIPS FOR DRIVING IN VARIOUS CONDITIONS
Always slow down in gusty crosswinds. This will allow you much better
control.
 Drive slowly onto curbs and, if possible, at a right angle. Avoid driving
onto high, sharp±edged objects and other road hazards. Failure to do so can
lead to severe tire damage resulting in tire bursts.
 When parking on a hill, turn the front wheels until they touch the curb so
that the vehicle will not roll. Apply the parking brake, and place the
transmission in ºPº. If necessary, block the wheels.
 Washing your vehicle or driving through deep water may get the brakes
wet. To see whether they are wet, check that there is no traffic near you and
then press the pedal lightly. If you do not feel a normal braking force, the
brakes are probably wet. To dry them, drive the vehicle cautiously while
lightly pressing the brake pedal with the parking brake applied. If they still
do not work safely, pull to the side of the road and call a Lexus dealer for
assistance.

DRIVING TIPS153
CAUTION
Before driving off, make sure the parking brake is fully
released and that the parking brake reminder light is off.
 Do not rest your foot on the brake pedal while driving. It
can cause dangerous overheating, needless wear, and poor
fuel economy.
 To drive down a long or steep hill, reduce your speed and
downshift. Remember, if you ride the brakes excessively,
they may overheat and not work properly. See page 140.
 Be careful when accelerating, upshifting, downshifting or
braking on a slippery surface. The abrupt change in engine
speed, such as sudden acceleration or engine braking, could
cause the vehicle to spin or skid.
 Do not drive in excess of the speed limit. Even if the legal
speed limit permits it, do not drive over 140 km/h (85 mph)
unless your vehicle has high±speed capability tires.
Driving over 140 km/h (85 mph) may result in tire failure,
loss of control and possible injury. Be sure to consult a tire
dealer to determine whether the tires on your vehicle are
high±speed capability tires or not before driving at such
speeds.
 Do not continue normal driving when the brakes are wet. If they are
wet, your vehicle will r equire a longer stopping distance, and it may
pull to one side when the brakes are applied. Also, the parking brake
will not hold the vehicle securely.
WINTER DRIVING TIPS
Make sure you have ethylene±glycol antifreeze in the radiator.
NOTICE
Do not use alcohol type antifreeze.
Check the condition of the battery and cables.
Cold temperatures reduce the capacity of any battery, so it must be in top shape
to provide enough power for winter starting. Page 219 tells you how to
visually inspect the battery. Your Lexus dealer and most service stations will
be pleased to check the battery charge level.
Make sure the engine oil viscosity is suitable for the cold weather.
See page 200 for recommended viscosity. Leaving a heavy summer oil in your
vehicle during winter months may cause harder starting. If you are not sure
about which oil to use, call your Lexus dealer ± they will be pleased to h\
elp.
Check the electronic ignition system for loose connections or obvious
damage.
Keep the door locks from freezing.
Squirt lock de±icer or glycerine into the locks to keep them from fre\
ezing.

DRIVING TIPS
156
Brakes and safety chains
Lexus recommends trailers with brakes that conform to any
applicable federal and state/provincial regulations.
 A safety chain must always be used between the towing vehicle and the
trailer. Leave sufficient slack in the chain for turns. The chain should
cross under the trailer tongue to prevent the tongue from dropping to
the ground in case it becomes damaged or separated. For correct
safety chain procedures, follow the hitch or trailer manufacturer's
recommendations.
CAUTION
 If the total trailer weight exceeds 450 kg (1000 lb.), trailer
brakes are required.
 Never tap into your vehicle's hydraulic system as it will
lower its braking effectiveness.
 Never tow a trailer without using a safety chain securely
attached to both the trailer and the vehicle. If damage
occurs to the coupling unit or hitch ball, there is possible
danger of the trailer wandering over into another lane.
Tires
Ensure that your vehicle's tires are properly inflated. Adjust the tire
pressure to the recommended cold tire pressure indicated below:
Tire pressure, kPa (kgf/cm
2 or bar, psi)
Front 220 (2.2, 32)
Rear 220 (2.2, 32)
 The trailer tires should be inflated to the pressure recommended by the
trailer manufacturer in respect to the total trailer weight.
Trailer lights
Trailer lights must comply with federal, state/provincial and local
regulations. See your local recreational vehicle dealer or rental agency for
the correct type of wiring and relays for your trailer. Check for correct
operation of the turn signals and stop lights e ach time you hitch up. Direct
splicing may damage your vehicle's electrical system and cause a
malfunction of your lights.
Break±in schedule
 Lexus recommends that you do not tow a trailer with a new vehicle or a
vehicle with any new power train component (engine, transmission,
differential, wheel bearing, etc.) for the first 800 km (500 miles) of driving.
Maintenance
If you tow a trailer, your vehicle will require more frequent maintenance
due to the additional load. For this information, please refer to the
scheduled maintenance information in the ºOwner's Manual Supplement/
Maintenance Scheduleº.
 Retighten all fixing bolts of the towing ball and bracket after
approximately 1000 km (600 miles) of trailer driving.
Pre±towing safety check
Check that your vehicle remains level when a loaded or unloaded trailer is
hitched. Do not drive if the vehicle has an abnormal nose±up or
nose±down condition, and check for improper tongue load, overload, worn
suspension or other possible causes.
 Make sure the trailer cargo is securely loaded so that it cannot shift.
 Check that your rear view mirrors conform to any federal, state/provincial
or local regulation. If they do not, install required rear view mirrors\
appropriate for towing purposes.

DRIVING TIPS
158

Crosswinds and rough roads will adversely affect 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.
 Because of the added load of the trailer, your vehicle's engine may overheat
on hot days (at temperatures over 30C [85 F]) when going up a long or
steep gr ade with a trailer. If the engine coolant temperature gauge indicates
overheating, immediately turn off the air conditioning (if in use), pull your
vehicle off the road and stop in a safe spot. See ºIf your vehicle overheatsº\
on page 166 of this manual.
 Always place wheel blocks under both the vehicle and trailer wheels when
parking. Apply the parking brake firmly. Put the transmission in ºPº.
Avoid parking on a slope with a trailer, but if it cannot be avoided, do so
only after performing the following: 1. Apply the brakes and keep them applied.
2. Have someone place wheel blocks under both the vehicle and trailer
wheels.
3. When the wheel blocks are in place, release your brakes slowly until the
blocks absorb the load.
4. Apply the parking brake firmly.
5. Shift into ºPº and turn off the engine.
When restarting out after parking on a slope:
1. With the transmission in ºPº position, start the engine. Be sure to k\
eep the
brake pedal depressed.
2. Shift into the º2º, ºLº or ºRº position.
3. Release the parking brake and brake pedal and slowly pull or back away
from the wheel blocks. Stop and apply your brakes.
4. Have someone retrieve the blocks.
CAUTION

Do not exceed 72 km/h (45 mph) or the posted towing speed
limit, whichever is lower. Because instability (swaying) of
a towing vehicle±trailer combination usually increases as
the speed increases, exceeding 72 km/h (45 mph) may cause
loss of control.
Slow down and downshift before descending steep or long downhill
grades. Do not make sudden downshifts.
 Avoid holding the brake pedal down too long or too fr equently. This
could cause the brakes to overheat and result in reduced braking
efficiency.
