Starting and driving
Electric power steering system warning display
Type 1
Type 2
When there is a malfunction in the system, the warn-
4
ing display will appear on the information screen in
the multi-information display.
CAUTION
l If the warning display appears during
driving, it may become harder to turn the
steering wheel.
If the warning display appears while driving
1. Stop the vehicle in a safe place and turn off
the engine.
2. Wait approximately 30 seconds and then re-
start the engine to check whether the warning
display goes out; if it then remains off, there
is no problem.

appears again while driving, we recommend
you to have your vehicle inspected.

Active stability control (ASC)*

E00616700373
The Active Stability Control (ASC) takes overall
control of the anti-lock brake system (ABS), trac-
tion control function and stability control function
to help maintain the vehicle's control and traction.
Please read this section in conjunction with the
page on the ABS, traction control function and sta-
bility control function.

CAUTION
l Do not over-rely on the ASC. Even the
ASC 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 may lead
to accidents. It is the driver's responsibil-
ity to drive carefully. This means taking
into account the traffic, road and environ-
mental conditions.
l Be sure to use the same specified type and
size of tyre on all 4 wheels. Otherwise, the
ASC may not work properly.
l Do not install any aftermarket limited-
slip differential (LSD) on your vehicle.
The ASC may stop functioning properly.

NOTE
l
An operation noise may be emitted from the
engine compartment in the following situa-
tions. The sound is associated with checking
the operations of the ASC. At this time, you
may feel a shock from the brake pedal if you
depress it. These do not indicate a malfunc-
tion.
• When the ignition switch is set to the
"ON" position.
• When the vehicle is driven for a while af-
ter the engine is turned on.
l
When the ASC is activated, you may feel a
vibration in the vehicle body or hear a whin-
ing sound from the engine compartment.
This indicates that the system is operating nor-
mally. It does not indicate a malfunction.
l When the ABS warning lamp is illuminated,
the ASC is not active.
Traction control function
E00619000074
On slippery surfaces, the traction control function
prevents the drive wheels from excessive spinning,
thus helping the vehicle to start moving from a stop-
ped condition. It also provides sufficient driving
force and steering performance as the vehicle turns
while pressing the acceleration pedal.
CAUTION
l When driving a vehicle on a snowy or icy
road, be sure to install snow tyres and
drive the vehicle at moderate speeds.
