2-4. Using other driving systems
Electronically modulated air suspension
The vehicle adjusts the action of the shock absorbers and maintains vehicle
height automatically in response to driving conditions to help provide
enhanced driving comfort and vehicle control.
■ Vehicle height adjustment
Vehicle’s height is maintained at the se lected le
vel regardless of the num-
ber of occupants and luggage weight.

When driving
Pre-collision system (if equipped)
■The pre-collision system may not operate effectively in the following situations:
●When traveling through a curve with objects on the edge of the road.
●When traveling through a curve with another vehicle passing in the opposite
direction.
●Narrow iron bridges.
●Metallic objects on the road.
●A steel plate on the road (e.g., at a construction site).
●When waiting to turn to the left in an in tersection with another vehicle passing in
the opposite direction.
●If your vehicle approaches another vehicle ahead very quickly.
The vehicle reacts to a frontal collision the instant before it happens using fol-
lowing components.
■ Pre-collision sensor
Uses the radar to detect possible obst acles ahead. Sensors then determine in
advance whether a crash is unavoidable.
■ Pre-collision seat belts (Front seat belts only)
Helps enhance their restraint performance by quickly retracting if an acci -
dent is calculated to be inevitable.
■ Pre-collision brake assist system
Once an accident is calculated to be inevitable, increased braking force will
be applied once the brake pedal is pressed.
■ Electronically modulated air suspension control
Once an accident is calculated to be inevitable, the vehicle adjusts the damp -
ing action of the shock absorbers to help keep the vehicle level.

2-5. Driving information
■Before towing
●Ensure that your vehicle’s tires are properly inflated. (P.283 )
●Trailer tires should be inflated according to the trailer manufacturer’s recom -
mendation.
●All trailer lights must work to be legal.
●Confirm all lights work each time you connect them.
●Check that your vehicle remains level when a loaded or unloaded trailer is
hitched. Do not drive if the vehicle is not level, and check for improper tongue
load, overloading, worn suspension, or other possible causes.
●Make sure the trailer cargo is securely loaded.
●Check that your rear view mirrors conform to any federal, state/provincial or
local regulations. If they do not, instal l rear view mirrors appropriate for towing
purposes.
■Break-in schedule
Lexus recommends that you do not use a new vehicle or a vehicle with any new
p

ower train components (engine, transmissi on, differential, wheel bearing, etc.) to
tow a trailer for the first 500 miles (800 km) of driving.
■Maintenance
●If you tow a trailer, your vehicle will require more frequent maintenance due to
the additional load. (see “Owner’s Manual Supplement/ Scheduled Mainte -
nance”)
●Retighten the fixing bolts of the towing ball and bracket after approximately
600 miles (1000 km) of trailer towing.

Fuse layout and amperage rating
■Engine compartment fuse box (with electronically modulated air
suspension)
Determining if it fuse has blown.
Blown fuse
Replace it with one of an appropri -
ate amperage rating. The amper -
age rating can be found on the fuse
bo
x lid.
Normal fuse
If the lights do not turn on even
after the fuse has been replaced, a
bulb may need replacement.
(
P.313)
If the replaced fuse blows again, have the vehicle inspected by your Lexus
dealer
