■Operation of the engine switch
●If the switch is not pressed shortly and firmly, the engine switch mode may not change or the engine may not start.
●If attempting to restart the engine immediately after turning the engine switch off, the
engine may not start in some cases. After turning the engine switch off, please wait a few seconds before restarting the engine.

WARNING
■When starting the engine
Always start the engine while sitting in the driver’s seat. Do not depress the accelerator pedal while starting the engine under any circumstances.
Doing so may cause an accident resu lting in death or serious injury.
■Caution while driving
If engine failure occurs while the vehicle is moving, do not lock or open the doors until
the vehicle reaches a safe and complete stop. Activation of the steering lock in this cir- cumstance may lead to an accident, resulting in death or serious injury.
■Stopping the engine in an emergency
If you want to stop the engine in an emer gency while driving the vehicle, press and hold the engine switch for more than 2 seconds, or press it briefly 3 times or more in succes- sion. ( P. 657)
However, do not touch the engine switch while driving except in an emergency. Turning the engine off while driving will not cause loss of steering or braking control, but the power assist to these systems will be lost. Th is will make it more difficult to steer and
brake, so you should pull over and stop the vehicle as soon as it is safe to do so.

Vehicles without Adaptive Variable Suspension System
Normal mode
Provides an optimal balance of fuel ec onomy, quietness, and dynamic perfor-
mance. Suitable for city driving.
Press the switch to change the driving mode to normal mode when Eco drive mode or sport mode is selected.
Eco drive mode
Helps the driver accelerate in an eco-friendly manner and improve fuel econ-
omy through moderate throttle characteristics and by controlling the opera-
tion of the air conditioning system (heating/cooling).
When not in Eco drive mode, if the driving mode select switch is turned to the left, the
Eco drive mode indicator will come on.
Sport mode
Controls the transmission and engine to provide quick, powerful acceleration.
This mode also changes the steering feel, making it suitable for when agile
driving response is desired, such as when driving on roads with many curves.
When not in sport mode, if the driving mode se lect switch is turned to the right, the “SPORT” indicator will comes on.
Driving mode select switch
The driving modes can be selected to suit driving conditions.

◆ABS (Anti-lock Brake System)
Helps to prevent wheel lock when the brakes are applied suddenly, or if the
brakes are applied while driving on a slippery road surface
◆Brake assist
Generates an increased level of braking force after the brake pedal is
depressed when the system detects a panic stop situation
◆VSC (Vehicle Stability Control)
Helps the driver to control skidding when swerving suddenly or turning on
slippery road surfaces.
◆VSC + (Vehicle Stability Control +)
Provides cooperative control of the ABS, TRC, VSC and EPS.
Helps to maintain directional stability when swerving on slippery road sur-
faces by controlling steering performance.
◆Trailer Sway Control
Helps the driver to control trailer sway by selectively applying brake pressure
for individual wheels and reducing driving torque when trailer sway is
detected.
◆TRC (Traction Control)
Helps to maintain drive power and prevent the drive wheels from spinning
when starting the vehicle or accelerating on slippery roads
◆Hill-start assist control
Helps to reduce the backward movement of the vehicle when starting on an
uphill
Driving assist systems
To help enhance driving safety and performance, the following systems oper-
ate automatically in response to various driving situations. Be aware, however,
that these systems are suppl ementary and should not be relied upon too heav-
ily when operating the vehicle.

◆EPS (Electric Power Steering)
Employs an electric motor to reduce the amount of effort needed to turn the
steering wheel
◆Dynamic Torque Control AWD system (AWD models)
Automatically switches from front-wheel drive to all-wheel drive (AWD)
according to the driving conditions, helping to ensure reliable handling and
stability. Examples of conditions where the system will switch to AWD are
when cornering, going uphill, starting off or accelerating, and when the road
surface is slippery due to snow, rain, etc.
◆Adaptive Variable Suspension System (if equipped)
Controls the damping force of the shock absorber of each wheel according to
the road and driving conditions, helping achieve a comfortable ride, excellent
driveability and a high level of stability.
If SPORT S+ mode is selected using the driving mode select switch, the
damping force will become more suitable for sporty driving. ( P. 418)
◆VDIM (Vehicle Dynamics Integrated Management) (if equipped)
Provides integrated control of the ABS, brake assist, TRC, VSC, hill-start
assist control and EPS systems
Helps to maintain vehicle stability when swerving on slippery road surfaces by
controlling the brakes and engine output
◆Emergency brake signal
When the brakes are applie d suddenly, the stop lights automatically flash to
alert the vehicle behind.
