FRONT
Securely install the vehicle recovery hook stored with jacking tools.
Make sure that the hook is properly secured in the stored place after
use.
WARNING:

Stand clear of a stuck vehicle.

Do not spin your tires at high speed. This could cause them
to explode and result in serious injury. Parts of your vehicle
could also overheat and be damaged.
CAUTION:

Tow chains or cables must be attached only to the vehicle
recovery hooks or main structural members of the vehicle.
Otherwise, the vehicle body will be damaged.

Do not use the vehicle tie downs to free a vehicle stuck in sand, snow, mud, etc. Never tow the
vehicle using the vehicle tie downs or recovery hooks.

Always pull the cable straight out from the front of the vehicle. Never pull on the hook at an angle.

AUTOMATIC TRANSMISSION
To tow a vehicle equipped with an automatic transmission, an appropriate vehicle dolly MUST be placed
under the towed vehicle's drive wheels. Always follow the dolly manufacture's recommendations when using
their product.
If the vehicle is stuck in sand, snow, mud, etc., use the following procedure:
1. Turn off the Vehicle Dynamic Control System.
2. Make sure the area in front and behind the vehicle is clear of obstructions.
3. Turn the steering wheel right and left to clear an area around the front tires.
4. Slowly rock the vehicle forward and backward.
Shift back and forth between R (reverse) and D (drive).
Apply the accelerator as little as possible to maintain the rocking motion.
Release the accelerator pedal before shifting between R and D.
Do not spin the tires above 35 mph (55 km/h).
5. If the vehicle can not be freed after a few tries, contact a professional towing service to remove the vehi-
cle.

Height sensor signal from height sensor connected to AFS control unit

Swivel position sensor signal from swivel position sensor built into both right and left swivel actuators con-
nected to AFS control unit
In response to the state of control, AFS control unit switches commands of AFS off indicator signal sent to uni-
fied meter and A/C amp. via CAN communication; and then turns on/off or blinks AFS off indicator lamp built in
the combination meter.
AFS (ADAPTIVE FRONT-LIGHTING SYSTEM)
AFS increases viewability of cornering direction by changing light axis automatically to the direction of travel
with low beam headlamps during vehicle's cornering.
AFS switch allows AFS function to be stopped.
AFS control unit determines the current vehicle conditions by each received signals, and sends commands to
the low beam headlamp to swivel. With the headlamps (HIGH/LOW) illuminated, the AFS switch on, engine
running and the A/T select lever in any position but range P or range R, the low beam headlamps are opera-
tive by AFS control unit commands.
As the steering wheel is turned to the left (right), the left (right) low beam headlamp will automatically swivel
angle in accordance with the steering angle and vehicle speed, and stop the operation when the steering
wheel is returned to the straight-ahead position.
Swivel operation allows drive signal to be sent to the swivel actuator on the side that AFS control unit is actu-
ated. Step motor built in swivel actuator adjusts low beam projector of headlamp to swivel angle that matches
drive signal. Swivel position sensor built in swivel actuator detects swivel angle and transmits a swivel position
sensor signal to the AFS control unit. AFS control unit monitors if swivel operation is performed normally via
swivel position sensor signal.

Swivel operation
*1: Included high beam illuminated.
*2: The swivel operates when running at approx. 25 km/h (15.5 MPH). When swivel operation is started, it works on until vehicle
stops.
*3: The low beam headlamps perform small movements when AFS control unit detects start of the engine. This is normal with ini-
tialization of swivel actuator by AFS control unit.Low beam

HEADLAMP AUTO AIMING
Headlamp auto aiming control automatically corrects vertical deviation of light axis that is brought by the
change of vehicle height with changing number of passenger and laden weight, and relieves dazzle to oncom-
ing vehicles.
AFS control unit determines the current vehicle conditions by each received signals, and sends commands to
the low beam headlamps to auto aiming. With the headlamps (HIGH/LOW) illuminated and engine running,
the low beam headlamps are operative by AFS control unit commands.
The height sensor is located on the left side of the rear suspension member and detects rear vehicle height
change by sensing the displacement of the rear suspension arm. And transmits a height sensor signal to the
AFS control unit.
With reference to the rear vehicle height under the empty condition, light axis of low beam with low rear vehi-
cle height is relatively higher than that with the empty condition. AFS control unit switches drive signal corrects
height of low beam axis to maintain height of light axis with empty condition.
Light axis of low beam with high rear vehicle height is relatively lower than that with empty condition. Light axis
of low beam with empty condition is set as upper limit of headlamp auto aiming control operation. Control to
correct deviation is not performed when light axis of low beam gets relatively higher than that with empty con-
dition. Timing of control is switched in accordance with driving conditions.

Headlamp auto aiming operation
*1: Included high beam illuminated
*2: Control timing of drive signal is switched by vehicle speed and accelerating/decelerating vehicle.
*3: Control is performed without regard to the condition of AFS switch. Headlamp auto aiming control function cannot be cancelled.

AFS OPERATION
When The Steering Wheel Is Turned To The Left
Swivel motor driving signal (1-phase) is transmitted when the steer-
ing wheel is turned to left approximately more than 10* degrees
(predetermined), with vehicle speed at approximately 25 km/h (15.5
MPH) or more, headlamps (HIGH/LOW) illuminated, AFS switch ON
and the engine running and the A/T select lever in any position
except range P or R.
* : Slightly different from the case when it is turned to the right.
Swivel motor driving signal (1-phase) is sent

to front combination lamp LH terminal 17

through AFS control unit terminal 15,

to AFS control unit terminal 38

through front combination lamp LH terminal 21.
And swivel motor driving signal (2-phase) is sent:

to front combination lamp LH terminal 16

through AFS control unit terminal 17,

to AFS control unit terminal 36

through front combination lamp LH terminal 20.
Swivel position sensor detects swivel angle during ignition switch ON, and transmits swivel position sensor
signals to the AFS control unit:
When ignition switch is turn to ON position, power is supplied

to front combination lamp LH terminal 15

through AFS control unit terminal 24.
When ignition switch is turn to ON position, swivel position sensor signal input is supplied

to AFS control unit terminal 29

through front combination lamp LH terminal 14.
Ground is supplied

to front combination lamp LH terminal 19

through AFS control unit terminal 27.
The low beam headlamp LH starts to swivel to the left.
The swivel motor driving signals are blocked and the swivel motion stops when the steering angle reaches
approximately more than 80 degrees (predetermined). The low beam headlamp will not swivel any further no
matter how further left. As the steering wheel is turned back to the right, the swivel motor driving signals (both
1-phase and 2-phase) will be reversed, causing low beam headlamp LH to start swiveling to the right. When
steering angle becomes smaller than predetermined value, the low beam headlamp is set in the straight-
ahead position, swivel motor driving signals are blocked and low beam headlamps stop swiveling.
When The Steering Wheel Is Turned To The Right
Swivel motor driving signal (1-phase) is transmitted when the steer-
ing wheel is turned to right approximately more than 10* degrees
(predetermined), with headlamps (HIGH/LOW) illuminated, AFS
switch ON, the engine running and the A/T select lever in any posi-
tion except range P or R.

ahead position, swivel motor driving signals are blocked and low beam headlamps stop swiveling.
AFS OFF INDICATOR OPERATION
In response to the state of control, AFS control unit switches com-
mands of AFS off indicator signal sent to unified meter and A/C amp.
via CAN communication; and then turns on/off or blinks AFS off indi-
cator lamp built in the combination meter depending on the following
condition.

Bulb check operation
AFS off indicator lamp is turned off after illuminating for one sec-
ond as a bulb check for AFS off indicator lamp when turn ignition
switch ON is detected.
NOTE:
AFS off indicator lamp is turned off without a lapse of one sec-
ond when start of the engine is detected.

AFS switch operation
AFS off indicator lamp is illuminated while AFS switch is OFF.
AFS off indicator lamp is turned off while AFS switch is ON.

System warning operation
AFS off indicator lamp illuminates at intervals of approximately one second when AFS control unit detects
any specific DTC (diagnosis trouble code), or when unified meter and A/C amp. cannot receive AFS off
indicator signals.
NOTE:
Unified meter and A/C amp. transmits a command to combination meter to blink AFS off indicator lamp
when they cannot receive AFS off indicator signal.
SWIVEL ACTUATOR INITIALIZATION
AFS control unit performs swivel operation to initialize swivel actuator when start of the engine is detected.
Straight-ahead position of low beam headlamps is adjusted by turning low beam headlamps to outside vehicle
with specified swivel angle after turning it to the center of vehicle and making sure that it reaches the stopper.
Swivel actuator initialization shall be performed every time when start of the engine is detected.
