Notes: 
If doors are unlocked with the central locking switch  
after activating the automatic central locking, and  
neither door is opened, then the doors remain unlocked  
even at vehicle speeds of approximately 9 mph 
(15 km / h) or more. 
If a door is opened from the inside at speeds of  
approximately 9mph (15km/h) or less with the 
automatic central locking activated, the door will again  
be automatically locked at speeds of approximately  
9 mph (15 km / h) or more. 
Important! 
When towing the vehicle, or with the vehicle on a  
dynamometer test stand, please, note the following: 
With the engine running, the vehicle doors will lock if  
the left front wheel spins at vehicle speeds of 
approximately 9 mph (15 km / h) or more. 
To prevent vehicle door locks from locking, deactivate  
the automatic central locking.  Emergency unlocking in case of accident 
The doors unlock automatically a short time after an  
accident in which an airbag or emergency tensioning 
retractor deploys (this is intended to aid rescue and  
exit). However, the key must still be in the steering lock  
position 1 or 2. 
Additionally the hazard warning flashers turn on  
automatically and the interior lights switch on for 
approximately 30 minutes.

Antitheft alarm system 
The indicator lamp is located in the center console. 
The antitheft alarm is automatically armed or disarmed  
with the remote control by locking or unlocking the  
vehicle. 
The antitheft alarm is armed within approximately  
15 seconds after locking the vehicle with the remote 
control. 
A blinking lamp in the center console indicates that the  
alarm is armed. 
Notes: 
Use of the key in the front door locks does not arm or  
disarm the antitheft alarm system. 
The alarm sounds when unlocking the driver’s door  
with the mechanical key. Cancel alarm by turning key in 
steering lock to position 1, or with the remote control by  
pressing button  Œ. 
If the vehicle battery voltage falls below 10 volts, the  
alarm is automatically canceled and the antitheft alarm 
system is disarmed. When the voltage is above this 
value again, the antitheft alarm system is armed again.  Operation: 
Once the alarm system has been armed, the turn signal  
lamps will flash rapidly (approximately 3 minutes) and 
the horn will sound intermittently (approximately  
30 seconds) when someone: 
•  opens a door, 
•  opens the liftgate, 
•  opens the hood, 
•  breaks a window, 
•  attempts to raise the vehicle. 
The alarm will stay on even if the activating element (a  
door, for example) is immediately closed. 
If the alarm stays on for more than 20 seconds, an  
emergency call is initiated automatically. See Tele Aid 
on page 148. 
Note: 
The alarm system will cycle three times when triggered. 
The interior lights are automatically switched on when  
the alarm comes on and go out when canceling the 
alarm.

Tow-away alarm and glass breakage sensor 
The switch is located in the overhead console. 
The tow-away alarm and glass breakage sensor are part  
of the antitheft alarm system. 
Once the alarm system has been armed, the turn signal  
lamps will flash rapidly and the horn will sound when 
someone attempts to raise the vehicle, or breaks a 
window and reaches into the passenger compartment.  The alarm will last approximately 3 minutes in the form  
of rapidly flashing turn signal lamps. At the same time 
the horn will sound for approximately 30 seconds. The 
alarm will stay on even if the vehicle is immediately 
lowered. 
If the alarm stays on for more than 20 seconds, an  
emergency call is initiated automatically. See Tele Aid 
on page 148. 
To prevent triggering the tow-away alarm feature, switch  
off the tow-away alarm and glass breakage sensor before  
towing the vehicle, or when parking on a surface subject 
to movement, such as a ferry or auto train. 
To do so, turn key in steering lock to position 1, then  
return it to position 0 and remove key from steering  
lock. 
Within 30 seconds, push left or right button. (On  
vehicles equipped with optional trip computer, push 
RESET or MODE button, display shows OFF.) 
Exit vehicle, and lock vehicle with remote control. 
The tow-away alarm and glass breakage sensor remain  
switched off until the key is inserted in steering lock 
and turned to position 1.

Seats, front 
Caution! 
Do not remove head restraints except when mounting  
seat covers. For removal see page 43. Whenever head 
restraints have been removed be sure to reinstall them 
before driving.
Wa r n i n g ! 
Do not adjust the driver’s seat while driving.  
Adjusting the seat while driving could cause the  
driver to lose control of the vehicle.Never ride in a moving vehicle with the backrest  
reclined. Sitting in an excessively reclined position  
can be dangerous. You could slide under the seat  
belt in a collision. If you slide under it, the belt 
would apply force at the abdomen or neck. That  
could cause serious or even fatal injuries. The  
backrest and seat belt provide the best restraint 
when the wearer is in an upright position and the  
belt is properly positioned on the body.Never place hands under seat or near any moving  
parts while a seat is being adjusted.
Wa r n i n g ! 
When leaving the vehicle always remove the key  
from the steering lock, and lock your vehicle.Do not leave children unattended in the vehicle or 
with access to an unlocked vehicle. Unsupervised 
use of vehicle equipment may cause serious  
personal injury.
