1653-4. Adjusting the steering wheel and mirrors
3
Operation of each component
IS250_EE(OM53C51E)
When either “L” or “R” of the mirror select switch is selected, the outside rear
view mirrors will automatically angle downwards when the vehicle is reversing in
order to give a better view of the ground.
To disable this function, select neither “L” nor “R”.
■Adjusting the mirror angle when the vehicle is reversing
With the shift lever in R, adjust the mirror angle at a desired position.
The adjusted angle will be memorized and the mirror will automatically tilt to
the memorized angle whenever the shift lever is shifted to R from next time.
The memorized downward tilt position of the mirror is linked to the normal position
(angle adjusted with the shift lever in other than R). Therefore, if the normal posi-
tion is changed after adjustment, the tilt position will also change.
When the normal position is changed, readjust the angle in reversing.
■Mirror angle can be adjusted when
The engine switch is in ACCESSORY or IGNITION ON mode.
■When the mirrors are fogged up
The outside rear view mirrors can be cleared using the mirror defoggers. Turn on the
rear window defogger to turn on the outside rear view mirror defoggers. (→P. 3 8 2 )
■Automatic adjustment of the mirror angle (if equipped)
A desired mirror face angle can be entered to memory and recalled automatically by the
driving position memory. (→P. 1 5 1 )
■Auto anti-glare function (if equipped)
When the anti-glare inside rear view mirror is set to automatic mode, the outside rear
view mirrors will activate in conjunction with the anti-glare inside rear view mirror to
reduce reflected light. (→P. 1 6 2 )
■Using automatic mode in cold weather
When automatic mode is used in cold weather, the door mirror could freeze up and
automatic stowing and return may not be possible. In this case, remove any ice and snow
from the door mirror, then either operate the mirror using manual mode or move the mir-
ror by hand.
■Customization
The automatic mirror folding and extending operation can be changed. (Customizable
features: →P. 5 5 1 )

■When starting off on an uphill
The hill-start assist control will activate. (→P. 2 6 5 )
■Driving in the rain
●Drive carefully when it is raining, because visibility will be reduced, the windows may
become fogged-up, and the road will be slippery.
●Drive carefully when it starts to rain, because the road surface will be especially slip-
pery.
●Refrain from high speeds when driving on an expressway in the rain, because there may
be a layer of water between the tires and the road surface, preventing the steering and
brakes from operating properly.
■Engine speed while driving
In the following conditions, the engine speed may become high while driving. This is due
to automatic up-shifting control or down-shifting implementation to meet driving condi-
tions. It does not indicate sudden acceleration.
●The vehicle is judged to be driving uphill or downhill
●When the accelerator pedal is released
●When the brake pedal is depressed while sport mode is selected
■Breaking in your new Lexus
To extend the life of the vehicle, observing the following precautions is recommended:
●For the first 300 km (186 miles):
Avoid sudden stops.
●For the first 800 km (500 miles):
Do not tow a trailer.
●For the first 1000 km (621 miles):
• Do not drive at extremely high speeds.
• Avoid sudden acceleration.
• Do not drive continuously in low gears.
• Do not drive at a constant speed for extended periods.
■Drum-in-disc type parking brake system
Your vehicle has a drum-in-disc type parking brake system. This type of brake system
needs bedding-down of the brake shoes periodically or whenever the parking brake
shoes and/or drum are replaced. Have any authorized Lexus dealer or repairer, or
another duly qualified and equipped professional, perform the bedding down operation.
■Operating your vehicle in a foreign country
Comply with the relevant vehicle registration laws and confirm the availability of the cor-
rect fuel. (→P. 5 4 0 )

Cargo and luggage
Take notice of the following information about storage precautions, cargo
capacity and load:
CAUTION
■Things that must not be carried in the trunk
The following things may cause a fire if loaded in the trunk:
●Receptacles containing gasoline
●Aerosol cans
■Storage precautions
Observe the following precautions.
Failure to do so may prevent the pedals from being depressed properly, may block the
driver’s vision, or may result in items hitting the driver or passengers, possibly causing
an accident.
●Stow cargo and luggage in the trunk whenever possible.
●To prevent cargo and luggage from sliding forward during braking, do not stack any-
thing in the enlarged trunk. Keep cargo and luggage low, as close to the floor as pos-
sible.
●When you fold down the rear seats, long items should not be placed directly behind
the front seats.
●Never allow anyone to ride in the enlarged trunk. It is not designed for passengers.
They should ride in their seats with their seat belts properly fastened.
●Do not place cargo or luggage in or on the following locations.
• At the feet of the driver
• On the front passenger or rear seats (when stacking items)
• On the package tray
• On the instrument panel
• On the dashboard
• In front of the navigation system screen (if equipped) or Lexus Display Audio
screen (if equipped)
●Secure all items in the occupant compartment.
■Load and distribution
●Do not overload your vehicle.
●Do not apply loads unevenly.
Improper loading may cause deterioration of steering or braking control which may
cause death or serious injury.

◆We i g h t l i m i t s
Check the allowable towing capacity, GVM (Gross Vehicle Mass), MPAC
(Maximum Permissible Axle Capacity), and permissible draw bar load before
towing. (→P. 5 3 8 )
◆To w i n g h i t c h / b r a c k e t
Lexus recommends the use of the Lexus hitch/bracket for your vehicle. Other
products of a suitable nature and comparable quality may also be used.
◆To prevent an accident
The handling of the vehicle will feel different when towing a trailer. Beware of
the 3 most common causes of towing-related accidents: driver error, exces-
sive speed, and overloading.
Trailer towing (vehicles with a towing package)
The strain of towing a trailer will have a negative impact on the running perfor-
mance, handling, fuel consumption and endurance of your vehicle. Use the
vehicle features in the correct manner and operate the vehicle with care for
safer driving and optimal comfort. Damage and/or malfunctions that occur as
a result of towing performed for commercial purposes are not covered by the
Lexus warranty.
Ask your local authorized Lexus dealer or repairer, or another duly qualified
and equipped professional for further details before towing, as there are addi-
tional legal requirements in some countries.

■Total trailer weight and permissible drawbar load
Total trailer weight
Weight of the trailer itself plus the
trailer load should be within the max-
imum towing capacity. Exceeding
this weight is dangerous. (→P. 5 3 8 )
When the total trailer weight is
greater than the vehicle weight, we
recommend the use of a friction sta-
bilizer (sway control device).
Permissible drawbar load
Allocate the trailer load so that the drawbar load is greater than 25 kg (55.1 lb.) or
4% of the towing capacity. Do not let the drawbar load exceed the indicated
weight. (→P. 5 3 8 )
■Information tag (manufacturer’s label)
Gross vehicle mass
The combined weight of the driver, passengers, towing hitch, total curb mass and
drawbar load should not exceed the gross vehicle mass by more than 100 kg
(220.5 lb.). Exceeding this weight is dangerous.
Maximum permissible rear axle capacity
The weight borne by the rear axle should not exceed the maximum permissible
axle capacity by 15% or more. Exceeding this weight is dangerous.
The values for towing capacity were derived from testing conducted at sea level.
Take note that engine output and towing capacity will be reduced at high altitudes.

■Tire information
●Increase the tire inflation pressure to 20.0 kPa (0.2 kgf/cm2 or bar, 3 psi) greater than
the recommended value when towing. (→P. 5 4 6 )
●Increase the air pressure of the trailer tires in accordance with the total trailer weight
and according to the values recommended by the manufacturer of your trailer.
■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).
■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 capacity.
●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.
■Maintenance
●Maintenance must be performed more frequently when using the vehicle for towing
due to the greater weight burden placed on the vehicle compared to normal driving.
●Retighten all bolts securing the hitching ball and bracket after towing for approximately
1000 km (600 miles).
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 and may result in damage. Apply a rust inhib-
itor to parts that will come in contact when attaching a steel bracket.
