Break-in schedule
Lexus recommends that vehicles fitted with new power train components
should not be used for towing trailers for the first 800 km (500 miles).
Maintenance
Maintenance must be performed more frequently when using the vehicle
for towing due to the greater weight burden placed on the vehicle com-
pared to normal driving.
Retighten all bolts securing the hitching ball and bracket after towing for
approximately 1000 km (600 miles).
Safety checks before towing
Check that the maximum load limit for the towing hitch/bracket hitch
ball is not exceeded. Bear in mind that the coupling weight of the trailer
will add to the load exerted on the vehicle. Also make sure that you will
not be towing a load that exceeds the maximum permissible axle capac-
ity.
Ensure that the trailer load is secure.
Supplementary outside rear view mirrors should be added to the vehicle
if the traffic behind cannot be clearly seen with standard mirrors. Adjust
the extending arms of these mirrors on both sides of the vehicle so that
they always provide maximum visibility of the road behind.
NOTICE
When the rear bumper strengthening material is aluminum
Ensure the steel bracket part does not come directly in contact with that
area.
When steel and aluminum come into contact, there is a reaction similar to
corrosion, which will weaken the section concerned which may result in
damage. Apply a rust inhibitor to parts that will come in contact when
attaching a steel bracket.
When installing a towing harness to the vehicle
To prevent inoperative stop lights and damage to the vehicle stop light wir-
ing, take care when connecting a trailer harness to the vehicle. A relay with
a separate power source must be added to limit the current draw on the vehi-
cle stop light wiring.

Guidance
Your vehicle will handle differently when towing a trailer. In order
to avoid accident, death or serious injury, keep the following in
mind when towing:
Checking connections between trailer and lights
Stop the vehicle and check the operation of the connection
between the trailer and lights after driving for a brief period as
well as before setting off.
Practicing driving with a coupled trailer
Get the feel for turning, stopping and reversing with the trailer
coupled by practicing in an area with no or light traffic.
When reversing with a coupled trailer, hold the section of the
steering wheel nearest to you and rotate clockwise to turn the
trailer left or counterclockwise to turn right. Always rotate
gradually to prevent steering error. Have someone guide you
when reversing to lessen the risk of accident.
Increasing vehicle-to-vehicle distance
At a speed of 10 km/h (6 mph), the distance to the vehicle run-
ning ahead of you should be equivalent to or greater than the
combined length of your vehicle and trailer. Avoid sudden brak-
ing that may cause skidding. Otherwise, the vehicle may spin
out of control. This is especially true when driving on wet or
slippery road surfaces.
Sudden acceleration/steering input/cornering
Executing sharp turns when towing may result in the trailer col-
liding with your vehicle. Decelerate well in advance when
approaching turns and take them slowly and carefully to avoid
sudden braking.

When driving
IS250/220d/200d_EEImportant points regarding turning
The wheels of the trailer will travel closer to the inside of the
curve than the wheels of the vehicle. To make allowance for this,
take the turns wider than you would normally.
Important points regarding stability
Vehicle movement resulting from uneven road surfaces and
strong crosswinds will affect handling. The vehicle may also be
rocked by passing buses or large trucks. Frequently check
behind when moving alongside such vehicles. As soon as such
vehicle movement occurs, immediately start to decelerate
smoothly by slowly applying the brakes. Always steer the vehi-
cle straight ahead while braking.
Passing other vehicles
Consider the total combined length of your vehicle and trailer
and ensure that the vehicle-to-vehicle distance is sufficient
before executing lane changes.
Transmission information
Refrain from driving in 6 (manual transmission) or 4 range in S
mode (automatic transmission) to maintain the effectiveness of
the engine brake and the charge performance of electrical com-
ponents.
If the engine overheats...
Towing a loaded trailer up a long steep incline in temperatures
exceeding 30C (85F) may result in the engine overheating. If
the engine coolant temperature gauge indicates that the engine is
overheating, turn the air conditioning off immediately, leave the
road and stop the vehicle in a safe place. (P. 525)
When parking the vehicle
Always place wheel chocks under the wheels of both the vehicle
and trailer. Firmly set the parking brake and shift the shift lever
to P for automatic transmissions, and 1 or R for manual trans-
missions.

CAUTION
Vehicle speed in towing
Observe the legal maximum speeds for trailer towing.
Before descending hills or long declines
Reduce speed and downshift. However, never downshift suddenly while
descending steep or long downhill grades.
Operation of the brake
Do not hold the brake pedal depressed often or for long periods.
Doing so may result in the brake overheating or reduce braking effects.
To avoid accident or injury
Do not use cruise control when you are towing.
Do not tow the vehicle with the compact spare tire installed.

3-4. Using the hands-free phone system (for mobile phones)
IS250/220d/200d_EE
Conditions under which the system will not operate
If using a mobile phone that does not support Bluetooth®
If the mobile phone is switched off
If you are outside service range
If the mobile phone is not connected
If the mobile phone's battery is low
If the mobile phone is behind the seat or in the glove box or console box
If metal is covering or touching the phone
When using the hands-free system
The audio system and voice guidance are muted when making a call.
If both parties speak at the same time, it may be difficult to hear.
If the incoming call volume is overly loud, an echo may be heard.
Try to face toward the microphone as much as possible when speaking.
In the following circumstances, it may be difficult to hear the other
party:
• When driving on unpaved roads
• When driving at high speeds
• When a window is open
• When the air conditioning is blowing directly on the microphone
• When the air conditioning is set to high

If your vehicle needs to be towed
Before towing
The following may indicate a problem with your transmission.
Contact any authorized Lexus dealer or repairer, or another duly
qualified and equipped professional, before towing.
The engine is running, but the vehicle will not move.
The vehicle makes an abnormal sound.
Emergency towing
If a tow truck is not available, in an emergency your vehicle may
be temporarily towed using a cable or chain secured to the emer-
gency towing eyelet(s). This should only be attempted on hard,
surfaced roads for short distances at low speeds.
A driver must be in the vehicle to steer and operate the brakes. The
vehicle’s wheels, drive train, axles, steering and brakes must be in
good condition.
If towing is necessary, we recommend having your vehicle towed by
any authorized Lexus dealer or repairer, or another duly qualified and
equipped professional, such as a commercial towing service, using a
lift-type truck or a flat bed truck.
Use a safety chain system for all towing, and abide by all state/provin-
cial and local laws.
If towing from the rear, the vehicle's front wheels and axles must be in
good condition. (P. 463)
If they are damaged, use a towing dolly or flat bed truck.
