The parking brake locks the vehicle's rear wheels. When parked, the vehicle monitors and automatically tightens the grip if necessary.
By pressing the parking brake button, marked P, next to the gear selector when you're at a standstill, you engage the parking brake. Your vehicle can automatically engage the parking brake in several situations.
The instrument panel indicates when the vehicle is in park and the parking brake is engaged.
Warning
Avoid parking on a slope in wintry conditions. The tires might lose traction, even if the parking brake is engaged. You are always responsible for safe parking. Check the parking brake warning symbol for the parking brake status.

Note
At high speeds, pressing and holding the parking brake button slows the vehicle down at a steady rate. This provides a backup alternative to braking normally. Only use the parking brake like this if you are unable to brake using the brake pedal.
