SmartKey
Important safety notes
GWARNING
If children are left unsupervised in the vehicle,
they could:
R open the doors, thus endangering other 
people or road users.
R get out and disrupt traffic.
R operate the vehicle's equipment.
Additionally, children could set the vehicle in
motion if, for example, they:
R release the parking brake.
R shifting the automatic transmission out of
park position P
R Start the engine.
There is a risk of an accident and injury. 
When leaving the vehicle, always take the 
SmartKey with you and lock the vehicle. Never
leave children or animals unattended in the
vehicle. Always keep the SmartKey out of
reach of children.
GWARNING
If you attach heavy or large objects to the 
SmartKey, the SmartKey could be uninten-
tionally turned in the ignition lock. This could
cause the engine to be switched off. There is a risk of an accident.
Do not attach any heavy or large objects to the SmartKey. Remove any bulky key rings before
inserting the SmartKey into the ignition lock.
!Keep the SmartKey away from strong
magnetic fields. Otherwise, the remote 
control function could be affected. 
Strong magnetic fields can occur in the 
vicinity of powerful electrical installations.
Do not keep the SmartKey: R with electronic devices, e.g. a mobile
phone or another SmartKey.
R with metallic objects, e.g. coins or metalfoil.
R inside metallic objects, e.g. a metal case.
Vehicles with KEYLESS-GO start function: do not keep the SmartKey in the cargo com-
partment. Otherwise, the SmartKey may not
be detected, e.g. when starting the engine
using the Start/Stop button.

Refueling
Important safety notes
GWARNING
Fuel is highly flammable. If you handle fuel 
incorrectly, there is a risk of fire and explo-sion. 
You must avoid fire, open flames, creating 
sparks and smoking. Switch off the engine
and, if applicable, the auxiliary heating before
refueling.
GWARNING
Fuel is poisonous and hazardous to health. 
There is a risk of injury. 
You must make sure that fuel does not comeinto contact with your skin, eyes or clothing 
and that it is not swallowed. Do not inhale fuel
vapors. Keep fuel away from children. 
If you or others come into contact with fuel, 
observe the following:
R Wash away fuel from skin immediately
using soap and water.
R If fuel comes into contact with your eyes,
immediately rinse them thoroughly with
clean water. Seek medical assistance with-
out delay.
R If fuel is swallowed, seek medical assis- 
tance without delay. Do not induce vomit-ing.
R Immediately change out of clothing which
has come into contact with fuel.
GWARNING
Electrostatic buildup can create sparks and 
ignite fuel vapors. There is a risk of fire andexplosion. 
Always touch the vehicle body before opening
the fuel filler flap or touching the fuel pump 
nozzle. Any existing electrostatic buildup is
thereby discharged.
!Do not use diesel to refuel vehicles with a
gasoline engine. Do not switch on the igni- tion if you accidentally refuel with the
wrong fuel. Otherwise, the fuel will enter
the fuel system. Even small amounts of the
wrong fuel could result in damage to the
fuel system and the engine. Notify a quali-
fied specialist workshop and have the fuel
tank and fuel lines drained completely.

Changing a wheel
Flat tire
The "Breakdown assistance" section ( Y page 284) contains information and notes
on how to deal with a flat tire. Information on driving with MOExtended tires in the event of
a flat tire can be found under "MOExtended
tires (tires with run-flat characteristics"( Y page 285).
Rotating the wheels
GWARNING
Interchanging the front and rear wheels may 
severely impair the driving characteristics if
the wheels or tires have different dimensions.
The wheel brakes or suspension components
may also be damaged. There is a risk of acci-
dent. 
Rotate front and rear wheels only if the wheels and tires are of the same dimensions.
Observe the instructions and safety notes in 
the "Changing a wheel" section ( Ypage 322).
The wear patterns on the front and rear tires
differ, depending on the operating conditions. Rotate the wheels before a clear wear patternhas formed on the tires. Front tires typically
wear more on the shoulders and the rear tires
in the center. 
If your vehicle's tire configuration allows, you can rotate the wheels according to the inter- 
vals in the tire manufacturer's warranty book
in your vehicle documents. If no warranty
book is available, the tires should be rotated every 3,000 to 6,000 miles (5,000 to
10,000 km), or earlier if tire wear requires.
Ensure the direction of rotation is maintained.
Clean the contact surfaces of the wheel and
the brake disc thoroughly every time a wheel
is rotated. Check the tire pressure and, if nec-
essary, restart the tire pressure loss warning system.
Direction of rotation
Tires with a specified direction of rotation 
have additional benefits, e.g. if there is a risk of hydroplaning. These advantages can only
be gained if the tires are installed correspond-
ing to the direction of rotation. 
An arrow on the sidewall of the tire indicates its correct direction of rotation.
Storing wheels
Store wheels that are not being used in a cool,dry and preferably dark place. Protect the 
tires from oil, grease, gasoline and diesel.
Mounting a wheel
Preparing the vehicle
X Stop the vehicle on solid, non-slippery and 
level ground.
X Apply the electric parking brake manually.
X Bring the front wheels into the straight-
ahead position.
X Shift the transmission to position P.
X Switch off the engine.
X Vehicles without KEYLESS-GO: remove
the SmartKey from the ignition lock.
X Vehicles with KEYLESS-GO start-func- 
tion or KEYLESS-GO: open the driver's
door. 
The on-board electronics now have status0 . This is the same as the SmartKey having
been removed.
