2-3. Operating the headlight and windshield wipers
2
When driving
Daytime running light system
The headlights turn on automatically (at a reduced intensity) whenever the
engine is started and the parking brake is released to make your vehicle
more visible to other drivers. Dayt ime running lights are not designed for
use at night.
■Headlight control sensor
■Automatic light off system
The headlights turn off automatically if the engine is stopped and the driver’s door is
opened wh

ile the headlights are turned on.
To turn the headlights on again, turn the key to ON, or turn the light switch off once
and then
back to or position.
■Automatic headlight leveling system
The level of the headlights is
automatically adjusted according to the number of
passengers and the loading condition of the vehicle to ensure that the headlights do
not interfere other road users.
■Customization
The time it takes for the headlights to automatically turn on or off can be changed.
(  P.384 )
The sensor may not function properly if an
object is placed on the sensor, or anything
that blocks the sensor is affixed to the wind-
shield. 
Doing so interferes with the sensor detect-
ing the level of ambient light and may cause
the automatic headlight system malfunc-
tion.

2-3. Operating the headlight and windshield wipers
Adaptive front lighting system (AFS)
To improve road illumination when turning, the right side headlight moves right
on right turns, and the left side headlight moves left on left turns.
Adaptive front lighting system

■Operating conditions
The system starts to operate when the v
ehicle’s speed increases above 6 mph (10
km/h), and stops when the vehicles speed drops below 6 mph (10 km/h).
■When the “AFS OFF” indicator light flashes,
This indicates a system failure. Have your vehicle checked at your Lexus dealer.

2-4. Using other driving systems
Driver assist systems
When VSC or TRAC is operating
If the vehicle is in danger of slip-
ping or the rear wheels spin, the
slip indicator ligh t flash to indicate
that the s

ystems have been
engaged.
A buzzer (intermittent) sounds
when VSC is operating.
To help enhance improve vehicle safety, the following systems operate auto-
matically in certain driving conditions.
■ ABS (Anti-lock Braking System)
Help ensure steering performance in th e event of sudden braking or driving
on slippery road surfaces.
■ BA (Brake Assist)
Generates an increased level of braking force after the brake pedal is
pushed, when the system detects a panic stop situation.
■VSC (Vehicle Stability Control)
Helps the driver to control skidding wh en swerving suddenly or turning on
slippery road surfaces.
■ TRAC (Traction Control)
Helps maintain drive power and prevents spinning the rear wheels when
starting the vehicle or accelerating on slippery roads.
■Pre-collision system (if equipped)
( P. 1 4 3 )

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 ABS, VSC and TRAC sys -
tems are operating. None of these indicates that a malfunction has occurred.
• A sound may be heard.
• 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 while the ABS is activated.
• The brake pedal may move forward slightly after the ABS is activated.

2-5. Driving information
Trailer towing tips
Your vehicle will handle differently when towing a trailer. The three main
causes of vehicle-trailer accidents are driver error, excessive speed and
improper trailer loading. Keep these in mind when towing.
• Before starting out, check the tra iler
’s lights and the vehicle-trailer
connections. Recheck after driving a short distance.
• Practice turning, stopping and reversi ng with the tr
ailer attached in an
area away from traffic until you be come accustomed to the feel of the
vehicle.
• Reversing with a trailer attached is dif
ficult 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.
NOTICE
■When installing a trailer hitch
●Use only the position recommended by your Lexus dealer. Do not install the
trailer hitch on the bumper; this may cause body damage.
●Do not use axle-mounted hitches as they can cause damage to the axle housing,
wheel bearings, wheels or tires.
■Brakes
Lexus recommends trailers with brakes that conform to any applicable federal and
sta

te/provincial requlations.
■Do not directly splice trailer lights
Direct splicing may damage your vehicle’s electrical system and cause a malfunc -
tion.

When driving
• 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 sk id, r
esulting in jackknifing and loss
of control. This is especially true on wet or slippery surfaces.
• Avoid jerky starts or sudden acceleration.
• Avoid jerky steering and sharp turn s, and slo
w down before making a
turn.
• Note that when making a turn, the tr ailer wheels will be closer than the
v
ehicle wheels to the inside of th e turn. Compensate by making a
larger than normal turning radius.
• Crosswinds and rough roads will ad v
ersely affect handling of your
vehicle and trailer, causing sway. Peri odically check the rear to prepare
for being passed by large trucks or buses, which may cause your vehi-
cle and trailer to sway. If s
waying occurs, firmly grip the steering wheel,
reduce speed immediately but gradually, and steer straight ahead.
Never increase speed. If you make no extreme correction with the
steering or brakes, your vehi cle and trailer will stabilize.
• Take care when passing other vehicl es. P
assing 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.
• In order to maintain efficient engine br
aking and electrical charging
performance, do not use overdrive. Transmission shift range position
must be in “4”, in the “S” mode.
• Due to the added load of the traile r
, 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 engine coolant temperature gauge indicates
overheating, immediately turn off the air conditioning (if in use), pull
your vehicle off the road and stop in a safe spot. See “If your vehicle
overheats” ( P.359 ).
