KNOWING THE INSTRUMENT PANEL

Warning lamps What it means
SRS warning lamp
There is a supplemental restraint system (“SRS”) warning lamp on the instrument panel. The system
checks itself every time the ignition switch is turned to the “ON” position or the operation mode is put in
ON. The SRS warning lamp will come on for several seconds and then go out. This is normal and
means the system is working properly.
If there is a problem involving one or more of the SRS components, the warning lamp will come on and
stay on.
The SRS warning lamp is shared by the SRS airbag and the seat belt pre-tensioner system.
On vehicles equipped with the ERA-GLONASS, if the ERA-GLONASS system operates, the SRS
warning lamp illuminates.
58) 59)
ABS warning lamp (where provided)
If there is a malfunction in the system, the ABS warning lamp will come on. Under normal conditions, the
ABS warning lamp comes on when the ignition switch is turned to the “ON” position or the operation
mode is put in ON and goes off a few seconds later.
NOTE: On vehicles with the rear differential lock and the Electronic Stability Control (ESC), the ESC and
ABS functions are suspended while the rear differential lock is activated. ESC indicator lamp, ESC OFF
indicator lamp and ABS warning lamp are illuminated while these functions are suspended. It does not
indicate a problem. When the rear differential lock is disengaged, these lamps go out and function again.
Refer to “ESC indicator lamp, ESC OFF indicator lamp”.
If only the ABS warning lamp illuminates:
Avoid hard braking and high-speed driving. Stop the vehicle in a safe place.
Restart the engine and check to see whether the lamp goes out after a few minutes driving; if it then
remains off during driving, there is no problem.
However, if the warning lamp do not disappear, or if they come on again when the vehicle is driven, we
recommend you to have the vehicle checked as soon as possible.
If the ABS warning lamp and brake warning lamp illuminate at the same time:
The ABS and brake force distribution function may not work, so hard braking could make the vehicle
unstable.
Avoid hard braking and high-speed driving.
Stop the vehicle in a safe place and we recommend you to have the vehicle checked.

KNOWING THE INSTRUMENT PANEL

When the ignition switch is set to the
“ON” position or the operation mode is
put in ON.
When the vehicle is driven for a while
after the engine is turned on.
NOTE When the ESC is activated, you
may feel a vibration in the vehicle body
or hear a whining sound from the
engine compartment. This indicates
that the system is operating normally. It
does not indicate a malfunction.
NOTE When the anti-lock brake
system warning lamp is illuminated, the
ESC is not active.
NOTE On vehicles with the rear
differential lock, the ESC and ABS
functions are suspended while the rear
differential lock is activated. ESC
indicator lamp, ESC OFF indicator lamp
and ABS warning lamp are illuminated
while these functions are suspended. It
does not indicate a problem. When the
rear differential lock is disengaged,
these lamps go out and function again.
Refer to “ABS warning lamp” and “ESC
indicator lamp, ESC OFF indicator
lamp”.
Electronic Stability Control function
The electronic stability control function
is designed to help the driver maintain
control of the vehicle on slippery roads
or during rapid steering maneuvers. It
works by controlling the engine output
and the brake on each wheel.NOTE The electronic stability control
function does not operate when the
drive mode-selector is in the “4L”
position (Easy select 4WD), “4LLc”
position (Super select 4WD II). When
the electronic stability control function is
operating with the drive mode-selector
in the “2H” or “4H” position (Easy select
4WD), “2H”, “4H” or “4HLc” position
(Super select 4WD II), setting the drive
mode-selector to the “4L” (Easy select
4WD), “4LLc” position (Super select
4WD II) position makes the electronic
stability control function deactivate
automatically.
NOTE The electronic stability control
function operates at speeds of about
15 km/h or higher.
NOTE On vehicles with the rear
differential lock, the electronic stability
control function does not operate when
the rear differential lock is activated.
“ESC OFF” switch
The electronic stability control function
is automatically activated when the
ignition switch is turned to the “ON”
position or the operation mode is put in
ON. You can deactivate the system by
pressing down the “ESC OFF” switch
for 3 seconds or longer.
When the electronic stability control
function is deactivated, the
indicator
will turn on. To reactivate the ESC,
momentarily press the “ESC OFF”
switch; the indicator
is turned off.
215) 216)
Driving hints
When extricating the vehicle from mud,
sand or fresh snow with the drive
mode-selector in the “2H”or
“4H”position (Easy select 4WD) or “2H”,
“4H” or “4HLc” position (Super select
4WD II), you may find that operation of
the ESC prevents the engine speed
from increasing in response to
depression of the accelerator pedal. If
this happens and the vehicle remains
stuck as a result, place the drive
mode-selector in the “4L” position
(Easy select 4WD), “4LLc” position
(Super select 4WD II), or turn the
electronic stability control switch OFF.
The vehicle will then be easier to
extricate. (Brake control of the active
traction control function is still working
to prevent wheel spins when the ESC
OFF switch is “OFF”, “4L” position
(Easy select 4WD) or “4LLc” position
243AHA106085
139
(Super select 4WD II) selected.)

NOTE If you continue to press the
“ESC OFF” switch after the electronic
stability control function is turned off,
the “mistaken operation protection
function” will activate and the electronic
stability control function will turn back
on.
NOTE Even if the electronic stability
control function is turned off, it may
activate depending on the vehicle’s
movement.
Active Traction Control function
On slippery surfaces, the active traction
control function prevents the drive
wheels from spinning excessive, thus
helping the vehicle to start moving from
a stopped condition. It also provides
sufficient driving force and steering
performance as the vehicle turns while
pressing the acceleration pedal.
217)
WARNING
201)The brake assist system is not a
device designed to exercise braking force
greater than its capacity. Make sure to
always keep a sufficient distance between
vehicles in front of you without relying too
much on the brake assist system.
202)The ABS cannot prevent accidents. It
is your responsibility to take safety
precautions and to drive carefully.203)To prevent failure of the ABS, be sure
all 4 wheels and tyres are the same size
and the same type.
204)Do not install any aftermarket limited
slip differential (LSD) on your vehicle. The
ABS may stop functioning properly.
205)The ABS exploits the grip available to
the full, but it cannot improve it. Therefore,
you should take great care when driving on
slippery surfaces, without taking
unnecessary risks.
206)When the ABS intervenes and you
notice the brake pedal pulsating, keep the
pedal pushed down and don’t be alarmed.
This will help you to stop in the shortest
distance possible, depending on the road
conditions.
207)If the ABS intervenes, it means you
have almost reached the grip limit between
the tyres and the road surface: slow down
to make sure that you drive in accordance
with the available grip.
208)The ABS cannot overrule the natural
laws of physics, and can’t increase the grip
available according to the condition of the
road.
209)The ABS cannot prevent accidents,
including those due to excessive speed on
corners, driving on low-grip surfaces or
aquaplaning.
210)The capability of the ABS must never
be tested irresponsibly and dangerously, in
such a way as to compromise personal
safety and the safety of others.211)Do not over-rely on the ESC. Even the
ESC cannot prevent the natural laws of
physics from acting on the vehicle. This
system, like any other system, has limits
and cannot help you to maintain traction
and control of the vehicle in all
circumstances. Reckless driving can lead
to accidents. It is the driver’s responsibility
to drive carefully. This means into account
the traffic, road and environmental
conditions.
212)The ESC system cannot prevent
accidents, including those due to excessive
speed on corners, driving on low-grip
surfaces or aquaplaning.
213)Be sure to use the same specified
type and size of tyre on all 4 wheels.
Otherwise, the ESC may not work
correctly.
214)Do not install any aftermarket limited
slip differential (LSD) on your vehicle. The
electronic stability control function may
stop functioning properly.
215)For safety reasons, the “ESC OFF”
switch should only be operated when the
vehicle is stopped.
216)Be sure to keep the electronic stability
control function on while driving in normal
circumstances.
217)When driving a vehicle on a snowy or
icy road, be sure to install snow tyres and
drive the vehicle at moderate speeds.

mode-selector until the 2WD/4WD
operation indicator lamp illuminates
again.
When parking, apply the parking brake
before stopping the engine and make
sure that the 2WD/4WD operation
indicator and the low range lamp are
not blinking during shifting process
between “4H” <–> “4L”. Otherwise, the
vehicle could unexpectedly move even
if the automatic transmission is in the
“P” (PARK) position.
If, after a “4H” <–> “4L” selection has
been made, the 2WD/4WD operation
indicator continues blinking and the
desired range is not actually selected,
return the drive mode selector to its
previous position. Place the steering
wheel in the straight ahead position,
drive the vehicle forward, and release
the accelerator pedal. Next, hold down
the clutch pedal (with manual
transmission) or place the selector lever
in the “N” (NEUTRAL) position (with
automatic transmission) and make the
range selection again.
If the low range lamp blinks when you
attempt to make a “4H” <–> “4L”
selection, a “4H” <–> “4L” selection
cannot be made. Stop the vehicle andrelease the accelerator pedal. Next,
hold down the clutch pedal (with

132)
IMPORTANT
129)The “4L” range gives maximum torque
for low-speed driving on steep slopes, as
well as sandy, muddy, and other difficult
surfaces. On vehicles with automatic
transmission, do not exceed speeds of
approximately 70 km/h in “4L” range.
130)Do not drive your vehicle in the “4H”
or “4L” on dry paved roads and highways.
Doing so may result in excessive tyre wear,
increased fuel consumption, and possible
noise generation. It may also increase the
differential oil temperature, which may
damage the drive system. Further, the drive
train will be subjected to excessive loading,
resulting in oil leakage, component seizure,
or other serious problems. On dry paved
roads and highways, drive the vehicle in
“2H” only.

difficult surfaces. On vehicles with
automatic transmission, do not exceed
speeds of approximately 70 km/h in “4LLc”
range.
134)Do not drive your vehicle in the
“4HLc” or “4LLc” position on dry paved
roads and highways. Doing so may result in
excessive tyre wear, increased fuel
consumption, and possible noise
generation. It may also increase the
differential oil temperature, which may
damage the drive system. Further, the drive
train will be subjected to excessive loading,
resulting in oil leakage, component seizure,
or other serious problems. On dry paved
roads and highways, drive the vehicle in
“2H” or “4H” only.
135)Do not operate the drive
mode-selector while the rear wheels of the
vehicle are slipping on snow or ice.
