.
Why does the brake pedal pulsate slightly when
applying the brakes? This can occur when the ABS activates, and does not indicate a
problem. Apply firm, steady pressure on the brake pedal. Never
pump the brake pedal.
The rear door cannot be
opened from inside the
vehicle. Why? Check if the childproof lock is in the
LOCK position. If so, open the rear door with the outside door handle.
To cancel this function, push the lever
to the UNLOCK position.
