Disc brakes wear indicator
Your vehicle has disc brakes.
When your brake pads are worn and new
pads are required, you will hear a high-
pitched warning sound from your front or
rear brakes (if equipped). You may hear
this sound come and go or it may occur
whenever you depress the brake pedal.
Please remember that some driving con-
ditions or climates may cause a brake
squeal when you first apply (or lightly
apply) the brakes. This is normal and
does not indicate a problem with your
brakes. Parking brake E070201AFD-EA
Applying the parking brake
To engage the parking brake, first apply
the foot brake and then without pressing
the release button, pull the parking brake
lever up as far as possible. In addition it
is recommended that when parking the
vehicle on a gradient, the shift lever
should be positioned in the appropriate
low gear on manual transaxle vehicles or
in the P (Park) position on automatic
transaxle vehicles.
