Adjusting
SeatsWarning!
G
All seat, head restraint, steering wheel, and 
rear view mirror adjustments, as well as fas-
tening of seat belts, must be done before 
the vehicle is put into motion.Warning!
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 seat 
back in an excessively reclined position as 
this can be dangerous. You could slide un-
der the seat belt in a collision. If you slide 
under it, the belt would apply force at the ab-
domen or neck. That could cause serious or 
fatal injuries. The seat backrest and seat 
belts provide the best restraint when the 
wearer is in a nearly upright position and 
belts are properly positioned on the body.
Your seat must be adjusted so that you can 
correctly fasten your seat belt (
page 43).
Never place hands under the seat or near 
any moving parts while a seat is being ad-
justed.
Warning!
G
When leaving the vehicle, always remove the 
SmartKey or SmartKey with KEYLESS-GO* 
from the starter switch, take it with you, and 
lock the vehicle.
Even with the SmartKey or SmartKey with 
KEYLESS-GO* removed from the starter 
switch or the SmartKey with KEYLESS-GO* 
removed from the vehicle, the power seats 
can be operated when the respective door is 
open. Therefore, do not leave children unat-
tended in the vehicle, or with access to an 
unlocked vehicle. Unsupervised use of vehi-
cle equipment may cause an accident 
and/or serious personal injury. 
Warning!
G
Children 12 years old and under must never 
ride in the front seat, except in a 
Mercedes-Benz authorized BabySmart
TM1
 
compatible child seat, which operates with 
the BabySmart
TM system installed in the ve-
hicle to deactivate the passenger front 
air bag when it is properly installed. Other-
wise they will be struck by the air bag when 
it inflates in a crash. If this happens, serious 
or fatal injury will result.
According to accident statistics, children 
are safer when properly restrained in the 
rear seating positions than in the front seat-
ing positions. Infants and small children 
must ride in back seats and be seated in an 
appropriate infant or child restraint system, 
which is properly secured with the vehicle's 
seat belt and top tether strap, or secured via 
lower anchors and top tether strap, fully in 
accordance with the child seat manufactur-
er’s instructions.

tive Corp.

A child’s risk of serious or fatal injuries is 
significantly increased if the child restraints 
are not properly secured in the vehicle and 
the child is not properly secured in the child 
restraint.
iWhen moving the seat, make sure 
there are no items in the footwell or be-
hind the seats. Otherwise you could 
damage the seats.

tion together with the settings for the 
steering wheel and the exterior rear 
view mirrors.

49 Getting started
Driving
Release the brake pedal.
Carefully depress the accelerator 
pedal.Once the vehicle is in motion, the automat-
ic central locking system engages and the 
locking knobs drop down.
After a cold start, the automatic transmis-
sion shifts at a higher engine revolution. 
This allows the catalytic converter to reach 
its operating temperature earlier.
For more information, see “Driving instruc-
tions” (
page 273).
Warning!
G
On slippery road surfaces, never downshift 
in order to obtain braking action. This could 
result in drive wheel slip and reduced vehi-
cle control. Your vehicle’s ABS will not pre-
vent this type of loss of control.!In order to avoid damaging the trans-
mission,
wait for the gear selection process 
to complete before setting the vehi-
cle in motion.
place the gear selector lever in 
positionR only when the vehicle is 
stopped.
!If you hear a warning signal and a mes-
sage appears in the multifunction dis-
play when driving off, you have 
forgotten to release the parking brake.
Release the parking brake.!Do not run cold engine at high engine 
speeds. Running a cold engine at high 
engine speeds may shorten the service 
life of the engine.
!Simultaneously depressing the acceler-
ator pedal and applying the brake re-
duces engine performance and causes 
premature brake and drivetrain wear.iYou can open a locked door from the 
inside. Open doors only when condi-
tions are safe to do so.
You can deactivate the automatic lock-
ing using the control system 
(page 168).
