• Pregnant women should also use a lap-
shoulder belt. The lap belt portion should be 
positioned as low as possible on the hips to 
avoid any possible pressure on the abdomen.• Never place your feet on the instrument panel 
or on the seat. Always keep both feet on the 
floor in front of the seat.Wa r n i n g !
USE CHILD RESTRAINTS PROPERLY.Children 12 years old and under must never ride in 
the front seat, except in a Mercedes-Benz 
authorized BabySmart
TM compatible child seat, 
which operates with the BabySmart
TM system 
installed in the vehicle to deactivate the passenger 
front airbag when it is properly installed.
Otherwise they will be struck by the airbag 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 seating positions. 
Infants and small children must ride in the back 
seats and be seated in an appropriate infant or 
child restraint system, which is properly secured 
with the vehicle’s seat belt, fully in accordance 
with the child seat manufacturer’s instructions.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.Children too big for child restraint systems must 
ride in back seats using regular seat belts. Position 
shoulder belt across chest and shoulder, not face or 
neck. A booster seat may be necessary to achieve 
proper belt positioning.

If an exterior mirror housing is forcibly pivoted from its 
normal position, it must be repositioned by applying 
firm pressure until it snaps into place.
Storing rear view mirror positions in memory
(only vehicles with memory function)
The exterior rear view mirror positions are stored in 
memory with the seat / steering wheel adjustment and 
can be recalled when necessary. See page 93 for notes 
on the memory function.
Wa r n i n g !
Exercise care when using the passenger side 
exterior mirror. The mirror surface is convex 
(outwardly curved surface for a wider field of 
view). Objects in mirror are closer than they 
appear. Check your inside rear view mirror or 
glance over your shoulder before changing lanes.

Drive sensibly – Save Fuel
Fuel consumption, to a great extent, depends on driving 
habits and operating conditions. 
To save fuel you should:
•keep tires at the recommended inflation pressures,
•remove unnecessary loads,
•remove roof rack when not in use,
•allow engine to warm up under low load use,
•avoid frequent acceleration and deceleration,
•have all maintenance work performed at regular 
intervals by an authorized Mercedes-Benz Center.
Fuel consumption is also increased by driving in cold 
weather, in stop-and-go traffic, on short trips and in hilly 
country.Drinking and driving
Ped al s
Wa r n i n g !
Drinking or taking drugs and driving can be a very 
dangerous combination. Even a small amount of 
alcohol or drugs can affect your reflexes, 
perceptions and judgement.The possibility of a serious or even fatal accident is 
sharply increased when you drink or take drugs 
and drive.Please don’t drink or take drugs and drive or allow 
anyone to drive after drinking or taking drugs.Wa r n i n g !
Keep driver’s foot area clear at all times. Objects 
stored in this area may impair pedal movement.

Power assistance
BrakesExcessive use of road salt and other snow melting 
chemicals spread on roads during the winter months 
may cause a build up of moisture or residue to form on 
the braking components. This build up or residue could 
cause light corrosion of the braking components if the 
vehicle is parked with the brakes cold. Apply steady and 
even braking pressure when stopping the vehicle to 
warm up and dry the brake components.
Important!
Please pay attention to the function of the brake assist 
system (BAS), see page 271.
The condition of the parking brake system is checked 
each time the vehicle is in the shop for the required 
maintenance service.
If the parking brake is released and the brake warning 
lamp in the instrument cluster stays on, the brake fluid 
level in the reservoir is too low.
Brake pad wear or a leak in the system may be the 
reason for low brake fluid in the reservoir.
Have the brake system inspected at an authorized 
Mercedes-Benz Center immediately.
Wa r n i n g !
When the engine is not running, the brake and 
steering systems are without power assistance. 
Under these circumstances, a much greater effort is 
necessary to stop or steer the vehicle.Wa r n i n g !
After driving in heavy rain for some time without 
applying the brakes or through water deep enough 
to wet brake components or salty road conditions, 
the first braking action may be somewhat reduced 
and increased pedal pressure may be necessary to 
obtain expected braking effect. Be sure to maintain 
a safe distance from vehicles in front.Resting your foot on the brake pedal will cause 
excessive and premature wear of the brake pads.It can also result in the brakes overheating thereby 
significantly reducing their effectiveness. It may 
not be possible to stop the vehicle in sufficient time 
to avoid an accident.

Specified tire pressures must be maintained. This 
applies particularly if the tires are subjected to high 
loads (e.g. high speeds, heavy loads, high ambient 
temperatures).
Aq uaplaning
Depending on the depth of the water layer on the road, 
aquaplaning may occur, even at low speeds and with 
new tires. Reduce vehicle speed, avoid track grooves in 
the road and apply brakes cautiously in the rain.Tire traction
The safe speed on a wet, snow covered or icy road is 
always lower than on a dry road.
You should pay particular attention to the condition of 
the road whenever the outside temperatures are close to 
the freezing point.
We recommend M+S rated radial-ply tires for the winter 
season for all four wheels to insure normal balanced 
handling characteristics. On packed snow, they can 
reduce your stopping distance as compared with 
summer tires. Stopping distance, however, is still 
considerably greater than when the road is not snow or 
ice covered.
Wa r n i n g !
Do not drive with a flat tire. A flat tire affects the 
ability to steer or brake the vehicle. You may lose 
control of the vehicle. Continued driving with a flat 
tire or driving at high speed with a flat tire will 
cause excessive heat build-up and possibly a fire.
Wa r n i n g !
If ice has formed on the road, tire traction will be 
substantially reduced. Under such weather 
conditions, drive, steer and brake with extreme 
caution. 

271 Driving systems
Te ch n i c a l
data Instruments 
and controlsOperationDrivingInstrument 
cluster displayPractical hints Car care Index Brake assist system (BAS)
The BAS is designed to maximize the vehicle’s braking 
capability during emergency braking maneuvers by 
having maximum power boost applied to the brakes 
more quickly in emergency braking conditions than 
might otherwise be afforded solely by the driver’s 
braking style. This can help reduce braking distances 
over what ordinary driving and braking style might do. 
The BAS complements the antilock brake system (ABS).Applying the brakes very quickly results in maximum 
BAS assistance.
To receive the benefit of the system you must apply 
continuous full braking power during the stopping 
sequence. Do not reduce brake pedal pressure.
Once the brake pedal is released, the BAS is deactivated.
If the BAS warning message is displayed, a malfunction 
has been detected in the system. The brake system 
functions in the usual manner, but without BAS.
With the ABS malfunctioning, the BAS is also switched 
off.
If a BAS warning message is displayed, have the BAS 
checked at your authorized Mercedes-Benz Center as 
soon as possible.
Wa r n i n g !
BAS cannot prevent the natural laws of physics 
from acting on the vehicle, nor can it increase 
braking efficiency beyond that afforded by the 
condition of the vehicle brakes and tires or the 
traction afforded. The BAS cannot prevent 
accidents, including those resulting from excessive 
speed in turns, following another vehicle too 
closely, or aquaplaning. Only a safe, attentive, and 
skillful driver can prevent accidents. The 
capabilities of a BAS equipped vehicle must never 
be exploited in a reckless or dangerous manner 
which could jeopardize the user’s safety or the 
safety of others.
