Safety guidelines for the seat belt, emergency 
tensioning retractor and airbag
If you believe that, even with the use of these 
guidelines, it would be safer for your front 
passenger seat occupant to have the passenger side 
door mounted side airbag deactivated, then 
deactivation can be accomplished upon your 
written election to do so at your authorized 
Mercedes-Benz Center at an additional cost. Please 
contact your local authorized Mercedes-Benz 
Center or call our Client Assistance Center at 
1-800-FOR-MERCedes (1-800-367-6372) for details.Wa r n i n g !
• Damaged seat belts or belts that were highly 
stressed in an accident must be replaced and 
their anchoring points must also be checked. 
Use only belts installed or supplied by an 
authorized Mercedes-Benz Center.
• Airbags and ETR’s are designed to function on 
a one-time-only basis. An airbag or emergency 
tensioning retractor (ETR) that was activated 
must be replaced.• Do not pass belts over sharp edges.• Do not make any modification that could 
change the effectiveness of the belts.• No modifications of any kind may be made to 
any components or wiring of the “SRS”. This 
includes changing or removing any component 
or part of the “SRS”, the installation of 
additional trim material, badges etc. over the 
steering wheel hub, passenger airbag cover, or 
door trim panels, and installation of additional 
electrical / electronic equipment on or near 
“SRS” components and wiring. Keep area 
between airbags and occupants free of objects 
(e.g. packages, purses, umbrellas, etc.).

notice to the subsequent owner that it is equipped with 
an “SRS” by a lerting  him to th e applicabl e section in t he 
Operator’s Manual.
• An airbag system component within the 
steering wheel gets hot after the airbag has 
inflated. Do not touch.• Improper work on the system, including 
incorrect installation and removal, can lead to 
possible injury through an unintended 
activation of the “SRS”.• In addition, through improper work there is 
the risk of rendering the “SRS” inoperative or 
causing unintended airbag deployment. Work 
on the “SRS” must therefore only be performed 
by an authorized Mercedes-Benz Center.
• For your protection and the protection of 
others, when scrapping the airbag unit or 
emergency tensioning retractor, our safety 
instructions must be followed. These 
instructions are available at your authorized 
Mercedes-Benz Center.• Given the considerable deployment speed and 
the textile structure of the airbags, there is the 
possibility of abrasions or other injuries 
resulting from airbag deployment.

Adjusting telescoping steering column
Unlocking:
Pull handle (1) out to its stop. The indicator lamp, 
located in the instrument cluster, comes on.
Adjusting:
To lengthen or shorten the steering column, pull out or 
push in steering wheel.
Locking:
Push handle (1) in until it engages. The indicator lamp, 
located in the instrument cluster, goes out.Important!
With the key in steering lock position 2, the indicator 
lamp in the instrument cluster comes on. It should go 
out when the engine is running.
If the indicator lamp does not go out after starting the 
engine, the adjustable steering column is not locked 
properly.
Do not drive the vehicle until you have properly locked 
the steering column.

Do not adjust the steering wheel while driving. The 
telescoping adjustment must be locked while 
driving. Adjusting the steering wheel while 
driving, or driving without the telescoping 
adjustment locked could cause the driver to lose 
control of the vehicle.

reached as quickly as possible.
The system will not h eat or cool a ny quicker by setting  a

The climate control removes considerable moisture from 
the air during operation in the cooling mode. It is 
normal for water to drip on the ground through ducts in 
the underbody.

See illustration for gearshift lever positions 
corresponding to the individual gears.
Stop the vehicle completely before shifting into reverse; 
to shift into reverse, pull the gearshift lever up.
Do not exceed the maximum engine speed in the 
individual gears. Refer to tachometer (see page 74) for 
engine speeds.Important!
When vehicle is parked, always be sure to engage first 
or reverse gear and firmly set parking brake. 
When parked on an incline, also turn front wheel 
towards the road curb.
Downshifting gears leading to overrevving the engine 
can result in transmission damage that is not covered 
by the Mercedes-Benz Limited Warranty.
Do not exceed engine speed limits, see page 74.

On slippery road surfaces as well as high engine 
speeds, never downshift in order to obtain braking 
action. This could result in drive wheel slip and 
reduced vehicle control. Your vehicle’s ESP will not 
prevent this type of loss of control.Wa r n i n g !

Stopping
For brief stops, e.g. at traffic lights, leave the 
transmission in gear and hold vehicle with the service 
brake.
For longer stops with the engine idling, shift into “N” 
or “P” and hold the vehicle with the service brake.
When stopping the vehicle on an uphill gradient, do not 
hold it with the accelerator, use the brake. This avoids 
unnecessary transmission heat build up.
Maneuvering
To maneuver in tight areas, e.g. when pulling into a 
parking space, control the vehicle speed by gradually 
releasing the brakes. Accelerate gently and never 
abruptly step on the accelerator.
To rock a vehicle out of soft ground (mud or snow), 
alternately shift from forward to reverse, while applying 
only slight partial throttle.
Rocking a vehicle free in this manner may cause the 
ABS or traction system malfunction indicator lamp to 
come on. Turn off and restart the engine to clear the 
malfunction indication.
Wa r n i n g !
Getting out of your vehicle with the selector lever 
not fully engaged in position “P” is dangerous. 
Also, when parked on an incline, posi tion “P” alone 
may not prevent your vehicle from moving, 
possibly hitting people or objects.Always set t he parki ng brake in addi tion to sh ifting 
to position “P”, see page 153 for parking brake. When parked on an incline, also turn front wheel 
towards the road curb.Wa r n i n g !
When leaving the vehicle always remove the key 
from the steering lock, and lock the vehicle. Do not 
leave children unattended in the vehicle, or with 
access to an u nlocked veh ic le. Ch ildren cou ld m ove
