CAUTION
SRS airbag precautions
Observe the following precautions regarding the SRS airbags.
Failure to do so may cause death or serious injury.
The driver and all passengers in the vehicle must wear their seat belts prop-
erly.
The SRS airbags are supplemental devices to be used with the seat belts.
The SRS driver airbag deploys with considerable force, and can cause death
or serious injury especially if the driver is very close to the airbag.
Since the risk zone for the driver’s airbag is the first 50 - 75 mm (2 - 3 in.) of
inflation, placing yourself 250 mm (10 in.) from your driver airbag provides
you with a clear margin of safety. This distance is measured from the center
of the steering wheel to your breastbone. If you sit less than 250 mm (10 in.)
away now, you can change your driving position in several ways:
• Move your seat to the rear as far as you can while still reaching the pedals
comfortably.
• Slightly recline the back of the seat.
Although vehicle designs vary, many drivers can achieve the 250 mm (10
in.) distance, even with the driver seat all the way forward, simply by
reclining the back of the seat somewhat. If reclining the back of your seat
makes it hard to see the road, raise yourself by using a firm, non-slippery
cushion, or raise the seat if your vehicle has that feature.
• If your steering wheel is adjustable, tilt it downward. This points the airbag
toward your chest instead of your head and neck.
The seat should be adjusted as recommended above, while still maintaining
control of the foot pedals, steering wheel, and your view of the instrument
panel controls.
1723-3. Adjusting the seats
IS300h_EE(OM53B95E)
When driving position memory is linked with door unlock operation
If the driver’s door is opened, the driver’s seat will move toward the memorized
position but stop slightly beforehand to allow easy access to the vehicle.
Turning the power switch to ACCESSORY or ON mode, or fastening the
driver’s seat belt moves the seat fully into the memorized position.
Operating the driving position memory after turning the power switch off
Memorized seat positions can be activated up to 180 seconds after the driver’s
door is opened and another 60 seconds after it is closed again. Memorized steer-
ing wheel position can be activated by pressing the power switch.
Correct seat position
When the seat is in the most forward or most backward position, and the seat is
being moved in those directions, the system may not correctly recognize the cur-
rent position and the memorized position will not be correctly recalled.
The auto away function for exiting
If the seat is already close to the rearmost position, the auto away function may
not operate when the driver exits the vehicle.
When the driving position is recalled by a memory linked door unlock operation
Since each memorized driving position is registered to a specific electronic key,
the driving position recalled may be different depending on the carried key.
When only doors other than the driver’s door are unlocked by the smart entry &
start system, the driving position will not be recalled. In this case, press a driv-
ing position memory button to recall the desired driving position.
Customization
The distance that the driver’s seat moves backward during the auto away func-
tion can be changed. (Customizable features: P. 575)
CAUTION
Seat adjustment caution
Take care during seat adjustment so that the seat does not strike the rear passen-
ger or squeeze your body against the steering wheel.
1823-4. Adjusting the steering wheel and mirrors
IS300h_EE(OM53B95E)
Mirror angle can be adjusted when
The power switch is in ACCESSORY or ON mode.
Linked mirror function when reversing (if equipped)
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 nei-
ther “L” nor “R”.
If the mirror angle adjustment switch is operated while the linked mirror func-
tion is in operation, the angle and position of the mirrors can be remembered,
and the mirrors will operate at the angle adjusted to the last time the linked mir-
ror function was operated.
However, because the mirrors move based on the angle they are in when the
linked mirror function is not operating, the mirror angle when the linked mirror
function is operating will also be changed if the mirrors are adjusted while the
function is not operating.
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.
404)
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. 168)
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. 179)
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 mirror by hand.
Customization
The automatic mirror folding and extending operation can be changed.

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 vehicle 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 execut-
ing lane changes.
Transmission information
To maintain engine braking efficiency, when using engine braking
when driving on a long steep downward grade, do not use the transmis-
sion in D. The vehicle must be driven in gear shift position “4” in S
mode. (P. 219)
If the engine overheats
Towing a loaded trailer up a long, steep incline in temperatures exceed-
ing 30C (85F) 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 vehi-
cle in a safe place.
(P. 555)
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.
