Driving your vehicle
Your vehicle may be equipped with
the ISG system, which reduces fuel
consumption by stopping and restarting
the engine automatically.
The engine starts automatically as soon
as the starting conditions are met.
NOTICE
When the engine automatically starts
by the ISG system, some warning lights
(ABS, ESC, ESC OFF, EPS or Parking
brake warning light) may turn on for a
few seconds. This happens because of
low battery voltage. It does not mean
the system is malfunctioning.
Activating the ISG
Prerequisite for activation
The ISG system operates in the following
situations.

[The driver’s seatbelt is fastened

[The driver’s door and bonnet are
closed

[The brake vacuum pressure is
adequate

[The battery sensor is activated and the
battery is sufficiently charged

[Outside temperature is not too low or
too high

[The vehicle is driven over a constant
speed and stops

[ The climate control system satisfies
the conditions

[The vehicle is sufficiently warmed up

[The incline is gradual

[The steering wheel is turned less than
180 degrees and then the vehicle
stops
Deactivating the ISG
OBC3N061014AU

ISG Indication
The ISG System is indicated by lamp on
the instrument cluster. If your vehicle is
equipped with a supervision cluster, the
notice will illuminate on the LCD display.
OBC3060009
The system may require the engine to
manually restart when the light on the
ISG OFF button will illuminate and if your
vehicle is equipped with a supervision
cluster, a warning message comes on
continuously.
OBC3N061014AU
OBC3070110TU/OBC3070111TU
The engine will not start if the shift lever
is moved from the N (neutral) stage to
the D (driving) stage, manual mode, or R
(reverse) stage without stepping on the
brake pedal whilst the engine is stopped
automatically. At this time, if you press
the brake it will be restarted.

Driving your vehicle
Conventional MT vehicle (not MHEV or
not equipped with LATE Restart) is able
to restart engine, only in Neutral gear.
If you select a gear, without depressing
clutch pedal fully, then warning will be
displayed with beep. You should restart
the engine in Neutral gear position.
Unintentionally, when the engine is
turned off or the vehicle is moving, if the
gear is engaged and the clutch pedal
is not pressed, the system displays the
warning message as shown below. At
this time, if the driver presses the clutch
pedal all the way, the engine restarts
automatically. (Only with Late Restart
equipped ISG system, except MHEV)

battery sensor needs to be calibrated
for approximately 4 hours with the
ignition off and then, turn the engine
on and off 2 or 3 times.
WARNING

anything in the engine room area,
stop the engine by turning the ignition
switch to the LOCK (OFF) position or
removing the ignition key.

Driving your vehicle
Hazardous driving conditions
When hazardous driving elements are
encountered such as water, snow,
ice, mud and sand, take the following
precautions:

[Drive cautiously and maintain a longer
braking distance.

[Avoid abrupt braking or steering.

[When your vehicle is stuck in snow,
mud, or sand, use the second
gear. Accelerate slowly to avoid
unnecessary wheel spin.

[Put sand, rock salt, tyre chains or
other non-slip materials under the
wheels to provide additional traction
whilst the vehicle becomes stuck in
ice, snow, or mud.
WARNING
Downshifting with an Automatic
transmission, whilst driving on slippery
surfaces can cause an accident. The
sudden change in tyre speed could
cause the tyres to skid. Be careful when
downshifting on slippery surfaces.
Rocking the vehicle
If it is necessary to rock the vehicle to
free it from snow, sand, or mud, first
turn the steering wheel right and left to
clear the area around your front wheels.
Then, shift back and forth between the
1st gear and R (Reverse, for manual
transmission vehicle) or R (Reverse)
and a forward gear (for Automatic
transmission vehicle/Dual clutch
transmission vehicle).
Try to avoid spinning the wheels, and do
not race the engine.
To prevent transmission wear, wait until
the wheels stop spinning before shifting
gears. Release the accelerator pedal
whilst shifting, and press lightly on the
accelerator pedal whilst the transmission
is in gear. Slowly spinning the wheels in
forward and reverse directions causes
a rocking motion that may free the
vehicle.
WARNING
If the vehicle is stuck and excessive
wheel spin occurs, the temperature
in the tyres can increase very quickly.
If the tyres become damaged, a tyre
blow out or tyre explosion can occur.
This condition is dangerous - you and
others may be injured. Do not attempt
this procedure if people or objects are
anywhere near the vehicle.
If you attempt to free the vehicle, the
vehicle can overheat quickly, possibly
causing an engine compartment fire or
other damages. Try to avoid spinning
the wheels as much as possible to
prevent overheating of either the tyres
or the engine. DO NOT allow the vehicle
to spin the wheels above 35 mph (56
km/h).

NOTICE
If you are still stuck after rocking the
vehicle a few times, have the vehicle
pulled out by a tow vehicle to avoid
engine overheating, possible damage
to the transmission, and tyre damage.
See “Towing” in chapter 8.
Smooth cornering
Avoid braking or gear changing in
corners, especially when roads are wet.
Ideally, corners should always be taken
under gentle acceleration.
Driving at night
Night driving presents more hazards
than driving in the daylight. Here are
some important tips to remember:

may be more difficult to see at night,
especially in areas where there may

headlamps of oncoming vehicles. You
could be temporarily blinded, and it
will take several seconds for your eyes
to readjust to the darkness.
Driving in the rain
Rain and wet roads can make driving
dangerous. Here are a few things to
consider when driving in the rain or on
slick pavement:
