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,
•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.

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 244 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.

Note:
Do not operate electric air pump longer that 6 minutes 
without interruption. Air pump could overheat! After air 
pump has cooled off, operate air pump again.
16. To switch off air pump, turn key in steering lock to 
position 0.
17. Reinstall valve tire cap.
18. Drive vehicle to distribute the sealant evenly inside 
the tire.Notes:
If TIREFIT is liquid, clean water and a damp cloth will 
remove the material from the vehicle or tire and wheel 
components. Once TIREFIT sealing material had dried, 
it can easily be peeled off and properly discarded.
Replace TIREFIT every 4 years.
Wa r n i n g !
If a tire pressure of 26 psi (1.8 bar) is not attained, 
tire is too severely damaged for TIREFIT to provide 
a reliable tire repair.In this case TIREFIT can not properly seal the tire.Do not drive the vehicle.Contact the nearest Mercedes-Benz Center or call 
Roadside Assistance.
Wa r n i n g !
Do not exceed vehicle speed of 50 mph (80 km / h). 
A TIREFIT repair is not designed to operate at 
higher speeds.Vehicle handling characteristics may change.After driving vehicle for an initial 10 minutes, 
check tire pressure. If tire pressure has fallen 
below 20 psi (1.3 bar) do not continue to drive the 
vehicle.If tire pressure is at least 20 psi (1.3 bar), inflate 
tire to correct pressure (see label on fuel filler 
flap), and drive vehicle to nearest tire repair 
facility to have tire repaired or replaced.Recommended duration of use: 300 miles (500 km) 
at 50 mph (80 km / h) with the recommended tire 
pressure. 

219 Tires, wheels
Te ch n i c a l
data Instruments 
and controlsOperation DrivingInstrument 
cluster displayPractical hintsCar care Index Tire inflation pressure
A table (see fuel filler flap) 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 underinflated 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..
