Driving instructions
Drive sensibly – Save Fuel
Fue l consumption, to a g rea t ex tent, depends on driv ing
habits and operating conditions.
To save fuel you should:
•keep tires at the recommended inflation pressures,
•remove unnecessary loads,
•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
Pedals
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.

What you should know at the gas station
Fuel supply
Open flap by pushing near front (arrow). Turn fuel cap
to the left and hold on to it until possible pressure in
tank has been released, then remove cap. Failure to
remove slowly could result in personal injury.See page 232 for notes on fuel filler flap, manual
release.
Fuel
To prevent fuel vapors from escaping into open air, fully
insert filler nozzle unit.
Only fill fuel tank until the filler nozzle unit cuts out —
do not top up or overfill.
Leaving the engine running and the fuel cap open can
cause the “CHECK ENGINE” lamp to illuminate.
Fuel tank capacity approximately 15.8 US gal (60.0 l).
This includes approximately 2.1 US gal (8.0 l) reserve.
Use premium unleaded gasoline: Posted Octane
Index 91 (Average of 96 RON / 86 MON).
Wa r n i n g !
Gasoline is highly flammable and poisonous. It
burns violently and can cause serious injury.
Whenever you are around gasoline, avoid inhaling
fumes and skin contact, extinguish all smoking
materials. Never allow sparks, flame or smoking
materials near gasoline!
P88.60-2028-21
Wa r n i n g !
Overfilling of fuel tank may result in creating
pressure in the system which could cause a gas
discharge such as the gas spraying back out upon
removing the filler nozzle which could cause
personal injury.

Xenon bulb for low beam: D2R (35W)
Wa r n i n g !
Because of high voltage in Xenon lamps, it is
dangerous to replace the bulb or repair the lamp
and its components. We recommend that you have
such work done by a qualified technician.

cluster displayPractical hintsCar care Index Tire inflation pressure
A table (see fuel filler f lap) lists the tire inflation
pressures specified for Mercedes-Benz recommended
tires as well as for the varying operating conditions.
Important!
Tire pressure changes by approximately 1.5 psi (0.1 bar)
per 18°F (10°C) of air temperature change. Keep this in
mind when checking tire pressure inside a garage -
especially in the winter.
Example:
If garage temperature = approximately +68°F (+20°C)
and ambient temperature = approximately +32°F (0°C)
then the adjusted air pressure = specified air pressure
+3psi (+0.2 bar).Tire pressures listed for light loads are minimum values
offering high driving comfort. Increased inflation
pressures for heavy loads produce favorable handling
characteristics with lighter loads and are perfectly
permissible. The ride of the vehicle, however, will
become somewhat harder.
Tire temperature and pressure increase with the vehicle
speed. Tire pressure should therefore only be checked
and corrected on cold tires. Correct tire pressure in
warm tires only if pressure has dropped below the
pressure listed in the table and the respective operating
conditions are taken into consideration.
An underinf lated tire due to a slow leak (e.g. due to a
nail in the tire) may cause damage such as tread
separation, bulging etc.. Regular tire pressure checks at
intervals of no more than 14 days are therefore
essential.

Caution!
To maintain the engine’s durability and performance,
premium unleaded gasoline must be used. If premium
unleaded is not available and low octane fuel is used,
follow these precautions:
•have the fuel tank filled only partially with unleaded
regular and fill up with premium unleaded as soon
as possible,
•avoid full throttle driving and abrupt acceleration,
•do not exceed
2/3 of maximum accelerator pedal
position, if the vehicle is fully loaded or operating in
mountainous terrain.Fuel requirements
Use only Premium unleaded meeting ASTM
standard D 439:
The octane number (posted at the pump) must be
91 min. It is an average of both the Research (R) octane
number and the Motor (M) octane number: [(R+M) / 2].
This is also known as ANTI-KNOCK INDEX.
Unleaded gasoline containing oxygenates such as
Ethanol, IPA, IBA and TBA can be used provided the
ratio of any one of these oxygenates to gasoline does not
exceed 10%, MTBE not to exceed 15%.
The ratio of Methanol to gasoline must not exceed 3%
plus additional cosolvents.
Using mixtures of Ethanol and Methanol is not allowed.
Gasohol, which contains 10% Ethanol and 90% unleaded
gasoline, can be used.
These blends must also meet all other fuel requirements
such as resistance to spark knock, boiling range, vapor
pressure etc..
