Using KEYLESS-GO to start the engine

As long as the SmartKey is in your vehicle, the vehicle can be started. Therefore, never leave children unattended in the vehicle, as they could otherwise accidentally start the engine.

When leaving the vehicle, always take the SmartKey with you and lock the vehicle. Do not leave children unattended in the vehicle, or with access to an unlocked vehicle. A child's unsupervised access to a vehicle could result in an accident and/or serious personal injury.

The Start/Stop button can be used to start the vehicle manually without inserting the SmartKey into the ignition lock. The Start/Stop button must be inserted into the ignition lock and the SmartKey must be in the vehicle. This mode for starting the engine operates independently of the ECO start/stop automatic engine start function.

Depress the brake pedal and keep it depressed.

•► To start a gasoline engine: press the Start/Stop button  once.

The engine starts.

•► To start a diesel engine: press the Start/ Stop button  once.

Preglow is activated and the engine starts.

If the engine is warm, the preglow time is shortened.
