Drive sensibly – save fuel
Fuel consumption, to a great extent, de-
pends on driving habits and operating con-
ditions.
To save fuel you should:
Keep tires at the recommended infla-
tion pressures.
Remove unnecessary loads.
Remove roof rack when not in use.
Allow engine to warm up under low 
load use.
Avoid frequent acceleration and decel-
eration.
Have all maintenance work performed 
at the intervals specified in the Mainte-
nance Booklet and as required by the 
Maintenance System (U.S. vehicles) or 
FSS (Canada vehicles). Contact an au-
thorized Mercedes-Benz Center.
Fuel consumption is also increased by driv-
ing in cold weather, in stop-and-go traffic, 
on short trips, and in hilly area.
Drinking and driving
PedalsPower assistance
Warning!
G
Drinking and driving and/or taking drugs 
and driving are very dangerous combina-
tions. Even a small amount of alcohol or 
drugs can affect your reflexes, perceptions 
and judgement.
The possibility of a serious or even fatal ac-
cident are greatly increased when you drink 
or take drugs and drive.
Do not drink or take drugs and drive or allow 
anyone to drive who has been drinking or 
taking drugs.
Warning!
G
Keep driver’s foot area clear at all times. Ob-
jects stored in this area may impair pedal 
movement.Warning!
G
With the engine not running, there is no 
power assistance for the brake and steering 
systems. In this case, it is important to keep 
in mind that a considerably higher degree of 
effort is necessary to brake and steer the ve-
hicle.

281 Operation
Driving instructions
Telephones and two-way radios
Radio transmitters, such as a portable tele-
phone or a citizens band unit should only 
be used inside the vehicle if they are con-
nected to an antenna that is installed on 
the outside of the vehicle.
Refer to the radio transmitter operation in-
structions regarding use of an external an-
tenna.
Catalytic converter
Your Mercedes-Benz is equipped with 
monolithic-type catalytic converters, an 
important element in conjunction with the 
oxygen sensors to achieve substantial con-
trol of the pollutants in the exhaust emis-
sions. Keep your vehicle in proper 
operating condition by following our rec-
ommended maintenance instructions as 
outlined in your Maintenance Booklet.
Warning!
G
Never operate radio transmitters equipped 
with a built-in or attached antenna (i.e. with-
out being connected to an external antenna) 
from inside the vehicle while the engine is 
running. Doing so could lead to a malfunc-
tion of the vehicle’s electronic system, pos-
sibly resulting in an accident and/or 
personal injury.
!To prevent damage to the catalytic con-
verters, only use premium unleaded 
gasoline in this vehicle.
Any noticeable irregularities in engine 
operation should be repaired promptly. 
Otherwise, excessive unburned fuel 
may reach the catalytic converter, 
causing it to overheat and potentially 
start a fire.
Warning!
G
As with any vehicle, do not idle, park or op-
erate this vehicle in areas where combusti-
ble materials such as grass, hay or leaves 
can come into contact with the hot exhaust 
system, as these materials could be ignited 
and cause a vehicle fire.

282 OperationDriving instructionsEmission control
Certain systems of the engine serve to 
keep the toxic components of the exhaust 
gases within permissible limits required by 
law.
These systems, of course, will function 
properly only when maintained strictly ac-
cording to factory specifications. Any ad-
justments on the engine should, therefore, 
be carried out only by qualified 
Mercedes-Benz Center authorized techni-
cians. 
Engine adjustments should not be altered 
in any way. Moreover, the specified service 
jobs must be carried out regularly accord-
ing to Mercedes-Benz servicing require-
ments. For details refer to the 
Maintenance Booklet.
Coolant temperature
During severe operating conditions, 
e.g. stop-and-go traffic, the coolant tem-
perature may rise close to approximately 
248°F (120°C).The engine should not be operated with 
the coolant temperature over 248°F 
(120°C). Doing so may cause serious en-
gine damage which is not covered by the 
Mercedes-Benz Limited Warranty.Warning!
G
Inhalation of exhaust gas is hazardous to 
your health. All exhaust gas contains carbon 
monoxide, and inhaling it can cause uncon-
sciousness and lead to death.
Do not run the engine in confined areas 
(such as a garage) which are not properly 
ventilated. If you think that exhaust gas 
fumes are entering the vehicle while driving, 
have the cause determined and corrected 
immediately. If you must drive under these 
conditions, drive only with at least one win-
dow fully open at all times.
Warning!
G
Driving when your engine is badly over-
heated can cause some fluids, which 
may have leaked into the engine com-
partment, to catch fire. You could be se-
riously burned.
Steam from an overheated engine can 
cause serious burns and can occur just 
by opening the hood. Stay away from 
the engine if you see or hear steam com-
ing from it.
Turn off the engine, get out of the vehicle 
and do not stand near the vehicle until the 
engine has cooled down.

294 OperationEngine compartmentBattery
Your vehicle’s battery is located on the 
right side of the trunk floor (
page 403).
The battery should always be sufficiently 
charged in order to achieve its rated ser-
vice life. Refer to Maintenance Booklet for 
battery maintenance intervals.
If you use your vehicle mostly for short-dis-
tance trips, you will need to have the bat-
tery charge checked more frequently.
When replacing the battery, always use 
batteries approved by Mercedes-Benz.
If you do not intend to operate your vehicle 
for an extended period of time, consult an 
authorized Mercedes-Benz Center about 
steps you need to observe.Batteries contain materials that can harm 
the environment if disposed of improperly. 
Recycling of batteries is the preferred 
method of disposal. Many states require 
sellers of batteries to accept old batteries 
for recycling.
G
Observe all safety instructions 
and precautions when handling 
automotive batteries. 
A
Risk of explosion
D
Keep flames or sparks away 
from battery. Do not smoke.
B
Battery acid is caustic. Do not 
allow it to come into contact 
with skin, eyes or clothing. 
In case it does, immediately 
flush affected area with clear 
water and seek medical help if 
necessary.

Tires and wheels
Tire care and maintenance
Regularly check your tire inflation pressure 
at least once a month. For more informa-
tion on checking tire inflation pressure see 
“Recommended tire inflation pressure” 
(page 305).Tire inspection
Every time you check your tire inflation 
pressure, you should also inspect your 
tires for the following:
excessive tread wear (
page 298)
cord or fabric showing through the 
tire’s rubber
bumps, bulges, cuts, cracks or splits in 
the tread or side of the tire
Replace the tire if you find any of the above 
conditions.
Make sure you also inspect the spare tire 
periodically for condition and inflation. 
Spare tires will age and become worn over 
time even if never used, and thus should be 
inspected and replaced when necessary.Life of tire
The service life of a tire is dependent upon 
varying factors including but not limited to:
Driving style
Tire inflation pressure
Distance driven
Warning!
G
Regularly check the tires for damage. Dam-
aged tires can cause tire inflation pressure 
loss. As a result, you could lose control of 
your vehicle.
Worn, old tires can cause accidents. If the 
tire tread is badly worn, or if the tires have 
sustained damage, replace them.
Warning!
G
Tires and spare tire should be replaced after 
six years, regardless of the remaining tread.
