CAUTION
Before using the LDA system
Do not rely solely on the LDA system. The LDA system does not drive the
vehicle automatically, nor does it reduce the amount of care you need to take.
As such, the driver must always assume full responsibility for understanding
his/her surroundings, for operating the steering wheel to correct the driving
line, and for driving safely.
Inappropriate or negligent driving could lead to an accident.
To avoid operating the LDA by mistake
Switch the LDA system off using the LDA switch when not in use.
Situations unsuitable for LDA system
Do not use the LDA system in any of the following situations.
Otherwise, the system may not function correctly and could result in an acci-
dent.
When driving with tire chains, a spare tire, or similar equipment
When there are objects or structures along the roadside that might be misin-
terpreted as lane markers (such as guardrails, a curb, reflector posts, etc.)
When driving on snowy roads
When pavement lane markers are difficult to see due to rain, snow, fog, sand
dust, etc.
When there are visible lines on the pavement from road repairs, or if the
remains of old lane markers are still visible on the road
When driving on a road with lane closures due to maintenance, or when driv-
ing in a temporary lane
4647-3. Do-it-yourself maintenance
IS300h_EE(OM53B95E)
Remove any dirt or foreign mat-
ter from the wheel contact sur-
face.
If foreign matter is on the wheel con-
tact surface, the wheel nuts may
loosen while the vehicle is in
motion, causing the tire to come off.
Install the spare tire and loosely tighten each wheel nut by hand by
approximately the same amount.
Turn the wheel nuts until the
washers come into contact with
the disc wheel.
Lower the vehicle.
Firmly tighten each wheel nut
two or three times in the order
shown in the illustration.
Tightening torque:
103 N•m (10.5 kgf•m, 76 ft•lbf)
