■TRAC (Traction Control) for H4 mode
Helps to maintain drive power and prevent the drive wheels from spinning
when starting the vehicle or accelerating on slippery roads
■Active TRAC (Traction Control) for L4 mode*
Helps to maintain drive power and prevent the 4 wheels from spinning
when starting the vehicle or accelerating on slippery roads, or in off-road
conditions
■Hill-start assist control
Helps to prevent the vehicle from rolling backward when starting on an
incline or slippery slope
■KDSS (Kinetic Dynamic Suspension System)
KDSS helps to enhance ride comfort and handling response by using a
hydraulic control system to control the suspension stabilizer bars in
response to road surface and driving conditions during cornering or off-
road driving

CAUTION
■TRAC/Active TRAC may not operate effectively when
Directional control and power may not be achievable while driving on slippery road
surfaces, even if the TRAC/Active TRAC is operating.
Do not drive the vehicle in conditions where stability and power may be lost.
■Hill- start assist control does not operate effectively when
Do not overly rely on the hill-start assist control. The hill-start assist control may not
operate effectively on steep inclines and roads covered with ice.
■When the VSC is activated
The slip indicator light flashes and a warning buzzer sounds. Always drive carefully.
Reckless driving may cause an accident. Exercise particular care when the indica-
tor light flashes and a buzzer sounds.
■When the TRAC or Active TRAC/VSC systems are turned off
Be especially careful and drive at a speed appropriate to the road conditions. As
these are the systems to ensure vehicle stability and driving force, do not turn the
TRAC or Active TRAC/VSC systems off unless necessary.
■Replacing tires
Make sure that all tires are of the same size, brand, tread pattern and total load
capacity. In addition, make sure that the tires are inflated to the recommended tire
inflation pressure level.
The ABS/Multi Terrain ABS and VSC systems will not function correctly if different
tires are installed on the vehicle.
Contact your Lexus dealer for further information when replacing tires or wheels.

Off-road drivingWhen driving your vehicle off-road, please observe the following precau-
tions to ensure your driving enjoyment and to help prevent the closure of
areas to off-road vehicles:
● Drive your vehicle only in areas where off-road vehicles are permitted
to travel.
● Respect private property. Get owner’s permission before entering pri-
vate property.
● Do not enter areas that are closed. Honor gates, barriers and signs
that restrict travel.
● Stay on established roads. When conditions are wet, driving tech-
niques should be changed or travel delayed to prevent damage to
roads.
■Additional information for off-road driving
For owners in U.S. mainland, Hawaii and Puerto Rico:
To obtain additional information pertaining to driving your vehicle off-road, consult
the following organizations:
●State and Local Parks and Recreation Departments
●State Motor Vehicle Bureau
●Recreational Vehicle Clubs
●U.S. Forest Service and Bureau of Land Management

CAUTION
■Off-road driving precautions
Always observe the following precautions to minimize the risk of death, serious
injury or damage to your vehicle:
●Drive carefully when off the road. Do not take unnecessary risks by driving in
dangerous places.
●Do not grip the steering wheel spokes when driving off-road. A bad bump could
jerk the wheel and injure your hands. Keep both hands and especially your
thumbs on the outside of the rim.
●Always check your brakes for effectiveness immediately after driving in sand,
mud, water or snow.
●After driving through tall grass, mud, rock, sand, rivers, etc., check that there is no
grass, bush, paper, rags, stone, sand, etc. adhering or trapped on the underbody.
Clear off any such matter from the underbody. If the vehicle is used with these
materials trapped or adhering to the underbody, a breakdown or fire could occur.
●When driving off-road or in rugged terrain, do not drive at excessive speeds,
jump, make sharp turns, strike objects, etc. This may cause loss of control or vehi-
cle rollover causing death or serious injury. You are also risking expensive dam-
age to your vehicle’s suspension and chassis.

Trailer towing tipsYour vehicle will handle differently when towing a trailer. Help to avoid an
accident, death or serious injury, keep the following in mind when towing:
● Speed limits for towing a trailer vary by state or province. Do not
exceed the posted towing speed limit.
● Lexus recommends that the vehicle-trailer speed limit is 65 mph (104
km/h) on a flat, straight, dry road. Do not exceed this limit, the posted
towing speed limit or the speed limit for your trailer as set forth in your
trailer owner’s manual, whichever is lowest. Instability of the towing
vehicle-trailer combination (trailer sway) increases as speed increases.
Exceeding speed limits may cause loss of control.
● Before starting out, check the trailer lights, tires and the vehicle-trailer
connections. Recheck after driving a short distance.
● Practice turning, stopping and rever sing with the trailer attached in an
area away from traffic until you become accustomed to the feel of the
vehicle-trailer combination.
● Reversing with a trailer attached is difficult and requires practice. Grip
the bottom of the steering wheel and move your hand to the left to
move the trailer to the left. Move your hand to the right to move the
trailer to the right. (This is generally opposite to reversing without a
trailer attached.) Avoid sharp or prolonged turning. Have someone
guide you when reversing to reduce the risk of an accident.
● As stopping distance is increased when towing a trailer, vehicle-to-
vehicle distance should be increased. For each 10 mph (16 km/h) of
speed, allow at least one vehicle and trailer length.
● Avoid sudden braking as you may skid, resulting in the trailer jackknif-
ing and loss of vehicle control. This is especially true on wet or slippery
surfaces.

CAUTION
■To avoid accident or injury
●Do not exceed the TWR, unbraked TWR, GCWR, GVWR or GAWR.
●If the gross trailer weight is over 2000 lb. (907 kg), a sway control device with
sufficient capacity is required.
●If the gross trailer weight is over 5000 lb. (2268 kg), a weight distributing hitch
with sufficient capacity is required.
●Adjust the tongue weight within the appropriate range. Place heavier loads as
close to the trailer axle as possible.
●Do not exceed 65 mph (104 km/h), the posted towing speed limit or the speed
limit for your trailer as set forth in your trailer owner’s manual, whichever is lowest.
Slow down sufficiently before making a turn, in crosswinds, on wet or slippery
surface, etc. to help avoid an accident. If you experience a vehicle-trailer instabil-
ity from reducing a certain speed, slow down and make sure you keep your vehi-
cle speed under the speed of which you experience the instability.
●Do not make jerky, abrupt or sharp turns.
●Do not apply the brakes suddenly as you may skid, resulting in jackknifing and
loss of vehicle control. This is especially true on wet or slippery surfaces.
●Do not exceed the trailer hitch assembly weight, gross vehicle weight, gross axle
weight and trailer tongue weight capacities.
●Do not use cruise control when towing.
●Slow down and downshift before descending steep or long downhill grades. Do
not make sudden downshifts while descending steep or long downhill grades.
●Vehicle-trailer instability is more likely on steep long down hills. Before descend-
ing steep or long downhill grades, slow down and downshift. Do not make sudden
downshifts when descending steep or long downhill grades. Avoid holding the
brake pedal down too long or applying the brakes too frequently. This could
cause the brakes to overheat and result in reduced braking efficiency.

■Reception sensitivity
●Cargo loaded on the roof luggage carrier, especially metal objects, may
adversely affect the reception of XM® Satellite Radio.
●It is difficult to maintain perfect radio reception at all times due to the continually

objects, such as trains and transmitters.
●The radio antenna is mounted inside the rear spoiler and the rear window. To
maintain clear radio reception, do not attach metallic window tinting or other
metallic objects to the antenna wire mounted inside the rear window.
