Parking brake
If you drive on wet roads or dirt-covered surfaces, road salt and/or dirt could get into the parking brake.
In order to prevent corrosion and a reduction in the braking power of the parking brake, observe the following:
- Gently depress the parking brake from time to time before beginning the journey.
- Drive a distance of approximately 110 yds (100 m) with a maximum speed of 12 mph (20 km/h).
WARNING
While performing this procedure please assure that the vehicle is stopped before applying the parking brake. Otherwise the rear wheels could lock up. You could lose control of the vehicle and cause an accident. In addition, the vehicle's brake lights do not light up when the parking brake is engaged. Make sure not to endanger any other road users when you engage the parking brake.
