3. After adjusting, be sure to tighten the cross rails by
turning knobs clockwise.
CAUTION
Make sure the cross rails are fixed securely by pushing
forward and rearward them. Failure to do so may cause
an unexpected accident or severe injury in the event of
emergency braking or a collision.
Follow the manufacturer's instructions and precautions when
installing the attachments or their equivalent.
CAUTION
When you load cargo on the roof luggage carrier,
observe the following:
 Place the cargo so that its weight is distributed
evenly between the front and rear axles.
 If loading long or wide cargo, never exceed the
vehicle overall length or width. (See Specificationsº
on page 608 for information on your vehicle overall
length and width.
 Before driving, make sure the cargo is securely
fastened on the roof luggage carrier.
 Loading cargo on the roof luggage carrier will make
the center of the vehicle gravity higher. Avoid high
speeds, sudden starts, sharp turns, sudden braking
or abrupt maneuvers, otherwise it may result in loss
of control or vehicle rollover due to failure to operate
this vehicle correctly.
 If driving for a long distance, on rough roads, or at
high speeds, stop the vehicle now and then during
the trip to make sure the cargo remains in its place.
 Do not exceed 58 kg (130 lb.) cargo weight on the roof
luggage carrier.
NOTICE
When loading the luggages, be careful not to scratch
the surface of the moon roof.

Fastening front, second and third seat belts
Adjust the seat as needed and sit up straight and well back
in the seat. To fasten your belt, pull it out of the retractor
and insert the tab into the buckle.
You will hear a click when the tab locks into the buckle.
The seat belt length automatically adjusts to your size and the
seat position.
The retractor will lock the belt during a sudden stop or on
impact. It also may lock if you lean forward too quickly. A slow,
easy motion will allow the belt to extend, and you can move
around freely. When a passenger's shoulder belt is completely extended and
is then retracted even slightly, the belt is locked in that position
and cannot be extended. This feature is used to hold the child
restraint system securely.
(For details, see Child restraintº on
page 184.) To free the belt again, fully retract the belt and then
pull the belt out once more.
If the seat belt cannot be pulled out of the retractor, firmly pull
the belt and release it. You will then be able to smoothly pull
the belt out of the retractor.
CAUTION
 After inserting the tab, make sure the tab and buckle
are locked and that the belt is not twisted.
 Do not insert coins, clips, etc. in the buckle as this
may prevent you from properly latching the tab and
buckle.
 If the seat belt does not function normally,
immediately contact your Lexus dealer. Do not use
the seat until the seat belt is fixed, because it cannot
protect an adult occupant or your child from injury.

Seat belt extender
If your seat belts cannot be fastened securely because they are
not long enough, a personalized seat belt extender is available
from your Lexus dealer free of charge.
Please contact your local Lexus dealer to order the proper
required length for the extender. Bring the heaviest coat you
expect to wear for proper measurement and selection of
length. Additional ordering information is available at your
Lexus dealer.
CAUTION
When using the seat belt extender, observe the
following precautions. Failure to follow these
instructions could reduce the effectiveness of the seat
belt restraint system in case of an accident, increasing
the chance of personal injury.
Remember that the extender provided for you may
not be safe when used on a different vehicle, for
another person, or at a different seating position than
the one originally intended. If the seat belt extender has been connected to the
driver's seat belt buckle without wearing the seat belt
when using the extender in the driver's seat, the SRS
driver's airbag system will judge that the driver wears
the seat belt even if not wearing it. In this case, the
driver's airbag may not activate correctly, causing
death or serious injury in the event of collision. Be
sure to wear the seat belt with the seat belt extender.

NOTICE
Do not use axle-mounted hitches as they can causedamage to the axle housing, wheel bearings, wheels ortires. 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.

higher and repeat steps 2 through 5.
7. Move the vehicle forward in the LOº (low) mode where the
hitch does not touch anything in the Nº (normal) mode.
8. Put the rear height control air suspension in the Nº (normal)
mode.
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 regulations. If they do not, install
required rear view mirrors appropriate for towing purposes.
Trailer towing tips
When towing a trailer, your vehicle will handle differently
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.

DRIVING TIPS
453

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 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. Transmission
must be 4º position. 
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 grade 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 If your vehicle overheatsº on page 468.
 Always place wheel blocks under both the vehicle and trailer
wheels when parking. Apply the parking brake firmly. Put
the transmission in Pº. 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 Pº and turn off the engine.

DRIVING TIPS
454When restarting out after parking on a slope:
1. With the transmission in Pº position, start the engine. Be
sure to keep the brake pedal depressed.
2. Shift into the 3º, 2º, Lº or Rº 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
frequently. This could cause the brakes to overheat
and result in reduced braking efficiency.
HOW TO SAVE FUEL AND MAKE
YOUR VEHICLE LAST LONGER
Improving fuel economy is easy Ð just take it easy. It will help
make your vehicle last longer, too. Here are some specific tips
on how to save money on both fuel and repairs:
 Keep your tires inflated at the correct pressure. Check
the pressure every two weeks, or at least once a month.
Underinflation causes tire wear and wastes fuel.
 Do not carry unneeded weight in your vehicle. Excess
weight puts a heavier load on the engine, causing greater
fuel consumption.
 Avoid lengthy warm-up idling. Once the engine is
running smoothly, begin driving Ð but gently. Remember,
however, that on cold winter days this may take a little
longer.
 Always keep the automatic transmission selector lever
in the Dº position when engine braking is not required.
Driving with the overdrive off will reduce the fuel economy.
(For details, see Automatic transmissionº on page 378.)
 Accelerate slowly and smoothly. Avoid jackrabbit starts.
 Avoid long engine idling. If you have a long wait and you
are not in traffic, it is better to turn off the engine and start
again later.
 Avoid engine over-revving. Use a gear position suitable
for the road on which you are traveling.
