2702-4. Using other driving systems
When the VSC/TRAC systems are operating
If the vehicle is in danger of slip-
ping or if any of the drive wheels
spins, the slip indicator light flashes
to indicate that the VSC/TRAC
systems are operating. ■ Enhanced VSC (Enhanced vehicle stability control) (if equipped) Provides cooperative control of the ABS, TRAC, VSC and EPS.
Helps to maintain directional stability when swerving on slippery road sur-
faces by controlling steering performance.
■ VDIM (Vehicle Dynamics Integra ted Management) (if equipped)Provides integrated control of the ABS, brake assist, TRAC, VSC, hill-start
assist control, and EPS systems.
Helps to maintain vehicle stability when swerving on slippery road sur-
faces by controlling the brakes and engine output.

When the message is displayed on the multi-information display showing that
TRAC has been disabled even if the VSC off switch has not been pressed
TRAC and hill-start assist control cannot be operated. Contact your Lexus dealer.■
Sounds and vibrations caused by th e ABS, VSC, TRAC and brake assist ●
A sound may be heard from the engi ne compartment when the engine is
started or just after the vehicle begins to move. This sound does not indicate that
a malfunction has occurred in any of these systems. ●
Any of the following conditions may occur when the above systems are operat-
ing. None of these indicates that a malfunction has occurred.
• Vibrations may be felt through the vehicle body and steering.
• A motor sound may be heard after the vehicle comes to a stop.
• The brake pedal may pulsate slightly after the ABS is activated.
• The brake pedal may move down slightly after the ABS is activated.■
EPS operation sound
When the steering wheel is operated, a motor sound (whirring sound) may be
heard. This does not indicate a malfunction.■
Reactivation of the TRAC /VSC systems
Turning off the engine after turning off the TRAC/VSC systems will automatically
reactivate them.■
Reactivation of the TRAC sy stem linked to vehicle speed
When only the TRAC system is turned off, the TRAC system will turn on when vehi-
cle speed increases. However, when both TRAC and VSC systems are turned off,
the systems will not turn on even when vehicle speed increases.■
Reduced effectiveness of the EPS system
The effectiveness of the EPS system is reduced to prevent the system from over-
heating when there is frequent steering in put over an extended period of time. The
steering wheel may feel heavy as a result. Should this occur, refrain from excessive
steering input or stop the vehicle and turn the engine off. The EPS system should
return to normal within 10 minutes.

CAUTION■
Off-road driving precautions
Always observe the following precautions to minimize the risk of death or 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 wh en 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, water, etc., check that there is no
grass, bush, paper, rags, stone, sand, etc. adhering or trapped to 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 te rrain, 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.
NOTICE■
To prevent water damage
Take all necessary safety measures to ensure that water damage to the engine or
other components does not occur. ●
Water entering the engine air intake will cause severe engine damage. ●
Water entering the automatic transmission will cause deterioration in shift quality,
locking up of your transmission accompanied by vibration, and ultimately dam-
age.
●
Water can wash the grease from wheel bearings, causing rusting and premature
failure, and may also enter the differentials, transmission and transfer case, reduc-
ing the gear oil’s lubricating qualities.

Trailer towing tips
Your 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 va ry 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 reversing with th e trailer attached in an
area away from traffic until you be come 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 yo ur hand to the right to move the
trailer to the right. (This is gene rally opposite to reversing without a
trailer attached.) Avoid sharp or prolonged turning. Have someone
guide you when reversing to redu ce the risk of an accident.
● As stopping distance is increased when towing a trailer, vehicle-to-
vehicle distance should be increas ed. 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 a loss of vehicle control. Th is is especially true on wet or slip-
pery surfaces.
● Avoid jerky starts or sudden acceleration.

When driving ● Avoid jerky steering and sharp turns, and slow down before making a
turn.
● Note that when making a turn, the tr ailer wheels will be closer than the
vehicle wheels to the inside of th e turn. Compensate by making a
wider than normal turning radius.
● Slow down before making a turn, in cross winds, on wet or slippery sur-
faces, etc.
Increasing vehicle speed can destabilize the trailer.
● Take care when passing other vehi cles. Passing requires considerable
distance. After passing a vehicle, do not forget the length of your
trailer, and be sure you have plenty of room before changing lanes.
● To maintain engine braking efficiency and charging system perfor-
mance when using engine braking, do not put the transmission in D.
● Instability happens more frequently when descending steep or long
downhill grades. Before descending, slow down and downshift. Do not
make sudden downshifts while descending steep or long downhill
grades.
● Avoid holding the brake pedal down too long or applying the brakes
too frequently. This could cause th e brakes to overheat and result in
reduced braking efficiency.
● Due to the added load of the trailer, your vehicle’s engine may overheat
on hot days (at temperatures over 85°F [30°C]) when driving up a
long or steep grade. If the eng ine coolant temperature gauge indicates
overheating, immediately turn off th e air conditioning (if in use), pull
your vehicle off the road and stop in a safe spot. (  P. 799)

Break-in schedule
If your vehicle is new or equipped with any new power train components (such as
an engine, transmission, differential or wheel bearing), Lexus recommends that you
do not tow a trailer until the vehicle has been driven for over 500 miles (800 km).
After the vehicle has been driven for over 500 miles (800 km), you can start tow-
ing. However, for the next 500 miles (800 km), drive the vehicle at a speed of less
than 50 mph (80 km/h) when towing a trailer, and avoid full throttle acceleration.■
Maintenance ●
If you tow a trailer, your vehicle will require more frequent maintenance due to
the additional load. (See “Warranty and Services Guide”, “Owner's Manual
Supplement” or “Scheduled Maintenance”.)●
Retighten the fixing bolts of the towing ball and bracket after approximately
600 miles (1000 km) of trailer towing.■
If trailer sway occurs
One or more factors (crosswinds, passing vehicles, rough roads, etc.) can adversely
affect handling of your vehicle and trailer, causing instability. ●
If trailer swaying occurs:
• Firmly grip the steering wheel. Steer straight ahead.
Do not try to control trailer sway ing by turning the steering wheel.
• Begin releasing the accelerator peda l immediately but very gradually to
reduce speed.
Do not increase speed. Do not apply vehicle brakes.
If you make no extreme correction with the steering or brakes, your vehicle and
trailer should stabilize. ●
After the trailer swaying has stopped:
• Stop in a safe place. Get all occupants out of the vehicle.
• Check the tires of the vehicle and the trailer.
• Check the load in the trailer.
Make sure the load has not shifted.
Make sure the tongue weight is appropriate, if possible.
• Check the load in the vehicle.
Make sure the vehicle is not ov erloaded after occupants get in.
If you cannot find any problems, the speed at which trailer swaying occurred is
beyond the limit of your particular vehicle-trailer combination.
Drive at a lower speed to prevent instability. Remember that swaying of the towing
vehicle-trailer increases as speed increases.
