2014 Lexus IS250 Care

1483-3. Adjusting the seats
IS250_EE(OM53C51E)
■Power easy access system (if equipped)
The driver’s seat and steering wheel move in accordance with engine switch mode and
the driver’s seat belt condition. (→P. 151)
■When adjusting the seat
●Take care when adjusting the seat so that the head restraint does not touch the ceiling.
●Vehicles with folding type rear seats: When folding down a rear seatback, if it interferes
with a front seatback, adjust the front seat position so that the seats no longer interfere
with each other. However, if adjusting the front seat position causes the correct driving
posture to not be maintained, return the rear seatback to its original position. (→P. 1 4 9 )
CAUTION
■When adjusting the seat position
●Take care when adjusting the seat position to ensure that other passengers are not
injured by the moving seat.
●Do not put your hands under the seat or near the moving parts to avoid injury.
Fingers or hands may become jammed in the seat mechanism.
●Make sure to leave enough space around the feet so they do not get stuck.
■Seat adjustment
To reduce the risk of sliding under the lap belt during a collision, do not recline the seat
more than necessary.
If the seat is too reclined, the lap belt may slide past the hips and apply restraint forces
directly to the abdomen, or your neck may contact the shoulder belt, increasing the risk
of death or serious injury in the event of an accident.
Adjustments should not be made while driving as the seat may unexpectedly move and
cause the driver to lose control of the vehicle.

■Cancelation procedure
Carry only the key you want to cancel and then close the driver’s door. If 2 or
more keys are in the vehicle, the driving position cannot be canceled properly.
Turn the engine switch to IGNITION ON mode.
While pressing the “SET” button, press and hold the door lock switch
(either lock or unlock) until the buzzer sounds twice.
If the button could not be canceled, the buzzer sounds continuously for approxi-
mately 3 seconds.
■Recalling the driving position using the memory recall function
●Different driving positions can be registered for each electronic key. Therefore, the
driving position that is recalled may be different depending on the key being carried.
●If a door other than the driver’s door is unlocked with the smart entry & start system, the
driving position cannot be recalled. In this case, press the driving position button which
has been set.
■Customization
The unlock door settings of the memory recall function can be customized.
(Customizable features: →P. 551)
CAUTION
■Seat adjustment caution
Take care during seat adjustment so that the seat does not strike the rear passenger or
squeeze your body against the steering wheel.

■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 )

CAUTION
Observe the following precautions.
Failure to do so may result in death or serious injury.
■When driving on slippery road surfaces
●Sudden braking, acceleration and steering may cause tire slippage and reduce your
ability to control the vehicle.
●Sudden acceleration, engine braking due to shifting, or changes in engine speed
could cause the vehicle to skid.
●After driving through a puddle, lightly depress the brake pedal to make sure that the
brakes are functioning properly. Wet brake pads may prevent the brakes from func-
tioning properly. If the brakes on only one side are wet and not functioning properly,
steering control may be affected.
■When shifting the shift lever
●Do not let the vehicle roll backward while the shift lever is in a driving position, or roll
forward while the shift lever is in R.
Doing so may cause the engine to stall or lead to poor brake and steering perfor-
mance, resulting in an accident or damage to the vehicle.
●Do not shift the shift lever to P while the vehicle is moving.
Doing so can damage the transmission and may result in a loss of vehicle control.
●Do not shift the shift lever to R while the vehicle is moving forward.
Doing so can damage the transmission and may result in a loss of vehicle control.
●Do not shift the shift lever to D while the vehicle is moving backward.
Doing so can damage the transmission and may result in a loss of vehicle control.
●Moving the shift lever to N while the vehicle is moving will disengage the engine from
the transmission. Engine braking is not available when N is selected.
●Be careful not to shift the shift lever with the accelerator pedal depressed. Shifting the
shift lever to a gear other than P or N may lead to unexpected rapid acceleration of
the vehicle that may cause an accident and result in death or serious injury.
■If you hear a squealing or scraping noise (brake pad wear indicators)
Have the brake pads checked and replaced by any authorized Lexus dealer or
repairer, or another duly qualified and equipped professional as soon as possible.
Rotor damage may result if the pads are not replaced when needed.
Moderate levels of brake pad and disc wear allow enhanced braking power. As a
result, the discs may wear more quickly than conventional brake discs. Therefore, when
replacing the brake pads, Lexus recommends that you also have the thickness of the
discs measured.
It is dangerous to drive the vehicle when the wear limits of the brake pads and/or those
of the brake discs are exceeded.

◆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.

Driving
IS250_EE(OM53C51E)
Your vehicle will handle differently when towing a trailer. In order to avoid acci-
dent, 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 starting 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 counter-
clockwise to turn it right. Always rotate a little at a time to prevent steering
error. Have someone guide you when reversing to lessen the risk of an
accident.
■Increasing vehicle-to-vehicle distance
At a speed of 10 km/h (6 mph), the distance to the vehicle running ahead of
you should be equivalent to or greater than the combined length of your vehi-
cle and trailer. Avoid sudden braking 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 colliding with your
vehicle. Decelerate well in advance when approaching turns and take them
slowly and carefully to avoid sudden braking.
■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 do.

2024-2. Driving procedures
IS250_EE(OM53C51E)
■Downshifting restriction warning buzzer
To help ensure safety and driving performance, downshifting operation may sometimes
be restricted. In some circumstances, downshifting may not be possible even when the
shift lever or paddle shift switch is operated. (A buzzer will sound twice.)
■Snow mode automatic deactivation
Snow mode is automatically deactivated if the engine switch is turned off after driving in
snow mode.
■Gear position display on the multi-information display
When Gear positions is selected for a Drive Information screen on the multi-information
display and the shift lever is in the D or M position, the currently selected gear position
will be displayed on the multi-information display. (The display changes according to the
shift lever position and driving conditions.)
■When driving with cruise control or dynamic radar cruise control activated
Even when performing the following actions with the intent of enabling engine braking,
engine braking will not activate because cruise control or dynamic radar cruise control
will not be canceled.
●While driving in the D position, downshifting to 5 or 4. (→P. 225, 229)
●When switching the driving mode to sport mode while driving in D position. (→P. 2 6 3 )
■If the shift lever cannot be shifted from P
→P. 5 2 3
■AI-SHIFT
The AI-SHIFT automatically selects the suitable gear according to driver performance
and driving conditions.
The AI-SHIFT automatically operates when the shift lever is in D. (Shifting the shift lever
to the M position cancels the function.)
CAUTION
■When driving on slippery road surfaces
Be careful of downshifting and sudden acceleration, as this could result in the vehicle
skidding to the side or spinning.
■Gear Shift Indicator display (if equipped)
For safety, the driver should not look only at the display. Refer to the display when it is
safe to do so while considering actual traffic and road conditions.
Failure to do so may lead to an accident.
