Things to remember when driving
Break-in procedures 
To ensure that your vehicle continues to 
furnish optimized economy of operation 
throughout an extended service life, we 
request that you devote careful attention 
to the following information.
Engine and differential 
Up to 1,200 miles/2,000 km: 
During this initial period you should attempt 
to avoid constant, steady-state operation 
and vary both vehicle and engine speeds 
as often as possible. Until the break-in 
period has been completed you should 
also refrain from exceeding the following: 
>4,500 rpm or 105 mph/170 km/h 
Always obey all official speed limits. 
Avoid full-throttle operation and use of the 
transmission's kick-down mode during 
these initial miles. 
Once  you have driven 1,200 miles/
2,000 km, the engine or vehicle speeds can 
be gradually increased. 
Tires 
Due to technical factors associated with 
their manufacture, tires do not achieve their 
full traction potential until after an initial 
break-in period. Therefore, drive reservedly 
during the first 200 miles/300 km.
Brake system 
Brakes require an initial break-in period of 
approx. 300 miles/500 km to achieve opti-
mized contact and wear patterns between 
brake pads and rotors.
Following component replacements
Observe the break-in instructions again if 
previously addressed components must be 
replaced again during driving later. 
General driving notes 
Hot exhaust system 
Extreme temperatures occur at the 
catalytic converter on this and every 
catalyst-equipped vehicle. Do not remove 
the heat shields installed adjacent to vari-
ous sections of the exhaust system, and 
never apply undercoating to them. When 
driving, standing at idle and while parking 
take care to avoid possible contact 
between the hot exhaust system and any 
highly flammable materials such as hay, 
leaves, grass, etc. Such contact could lead 
to a fire, accompanied by the risk of serious 
property damage as well as personal 
injury.< 
Air conditioning 
Condensation forms in the air conditioner 
system during operation, and then exits 
under the vehicle. Traces of condensed 
water under the vehicle are thus normal.
Before driving into a car wash 
1.Fold in the exterior mirrors, refer to 
page53, as otherwise they could be 
damaged due to the width of the vehicle 
2.Leave the remote control in the ignition 
lock, as otherwise the P position of the 
automatic transmission will automati-
cally be selected when the remote con-
trol is removed. Refer to page63 
and69.
With Comfort Access, be sure to 
observe the instructions on page63
3.Release the parking brake, especially 
when you have activated Automatic 
Hold. Refer to page64 and65.

Fuel specification 
The engine uses lead-free gasoline only.
Required fuel
Premium unleaded gasoline,
minimum octane rating: 91
Minimum octane rating corresponds to the 
Anti Knock Index AKI and is determined 
according to the so-called (R+M)/2 
method.
Do not use leaded gasoline, as other-
wise the lambda probe and catalytic 
converter will be permanently damaged.< 
Use high-quality brands
Field experience has indicated significant 
differences in fuel quality: volatility, compo-
sition, additives, etc., among gasolines 
offered for sale in the United States and 
Canada. Fuels containing up to and includ-
ing 10 % ethanol or other oxygenates with 
up to 2.8 % oxygen by weight, that is, 
15 % MTBE or 3 % methanol plus an equiv-
alent amount of co-solvent, will not void the 
applicable warranties with respect to 
defects in materials or workmanship.
The use of poor-quality fuels may 
result in drivability, starting and stall-
ing problems, especially under certain 
environmental conditions such as high 
ambient temperature and high altitude. 
Should you encounter drivability problems 
which you suspect could be related to the 
fuel you are using, we recommend that you 
respond by switching to a recognized high-
quality brand. 
Failure to comply with these recommenda-
tions may result in unscheduled mainte-
nance.<
