If the key in the steering lock is in position 1 or 2, the 
vehicle cannot be locked or unlocked with the remote 
control.
If the vehicle cannot be locked or unlocked:
•Check the batteries of the remote control, see 
page 270.
•Synchronize the remote control, see page 271.Central locking system

centrally locked and unlocked via remote control.
With vehicle centrally locked, the liftgate can also be 
unlocked by using the remote control.

Wa r n i n g !
A driver’s attention to the road must always be his /
her primary focus when driving. For your safety 
and the safety of others, we recommend that you 
pull over to a safe location and stop before placing 
or taking a telephone call. If you choose to use the 
telephone while driving, please use the hands-free 
device and only use the telephone when road and 
traffic conditions permit.Some jurisdictions prohibit the driver from using a 
cellular telephone while driving a vehicle.Bear in mind that at a speed of just 30 mph 
(approximately 50 km / h), your vehicle is covering 
a distance of approximately 50 feet (approximately 
14 m )  e v e r y  s e c o n d .  
Never operate radio transmitters equipped with a 
built-in or attached antenna (i.e. without being 
connected to an external antenna) from inside the 
vehicle while the engine is running. Doing so could 
lead to a malfunction of the vehicle’s electronic 
system, possibly resulting in an accident and 
personal injury.Wa r n i n g !
Some jurisdictions prohibit the driver from using a 
cellular telephone while driving a vehicle. Whether 
or not prohibited by law, for safety reasons, the 
driver should not use the cellular telephone while

the MCS, radio or telephone
1 if road and traffic 
conditions permit.
Bear in mind that at a speed of just 30 mph 
(approximately 50 km / h), your vehicle is covering 
a distance of approximately 50 feet (approximately 
14 m )  e v e r y  s e c o n d .
Wa r n i n g !
Never operate radio transmitters equipped with a 
built-in or attached antenna (i.e. without being
