Quick Reference GuideWhat to Do IfThe ignition switch does  not turn from 
(0 to (q . 
Why? ●
The steering wheel  may be locked.
● Try to turn the steering wheel left and right  
while turning the ignition key.
The ignition switch does  not turn from 
(q  to (0  and 
I cannot remove the key.

.
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.
