please consult a qualified specialist workshop
in advance. You could otherwise damage the
drive train or the brake system.
If you activate or deactivate the all-wheel drive
in a vehicle with this option, ESP
®will be deac-
tivated for the duration of the activation/deac-
tivation process.
If ESP
®is malfunctioning, the hindicator
lamp lights up while the engine is running and
the engine power may be reduced
(
Ypage 194).
iOnly use wheels with the recommended tire
sizes. Only then will ESP®function properly.
4ETS (Electronic Traction System)
!A function or performance test should only
be carried out on a two-axle dynamometer.
Before you operate the vehicle on such a
dynamometer, please consult a qualified
workshop. You could otherwise damage the
drive train or the brake system.
4ETS is only active when all-wheel drive is acti-
vated (
Ypage 148).
4ETS ensures permanent drive for all four
wheels, and together with ESP
®it improves the
vehicle's traction.
If a driven wheel spins due to lack of traction:
RWhen pulling away, make use of the traction
control integrated in ESP®. Depress the
accelerator pedal as far as necessary.
RWhile driving, slowly take your foot off the
accelerator pedal.
In wintry driving conditions, always use winter
tires (M+S tires) and if necessary, snow chains
(
Ypage 249). This is the only way to get the full
benefit from the all-wheel drive system.
Crosswind Assist
Crosswind Assist does not work if ESP®is deac-
tivated or disabled because of a malfunction.
Crosswind Assist does not react:
Rin the event of severe jolts and vibrations, e.g.
as a result of uneven surfaces or potholes
Rif the vehicle loses traction, e.g. on snow or
ice or when aquaplaning
Rto large and sudden steering movements by
the driver Crosswind Assist is operational again as soon as
the driving conditions return to normal.
Crosswind Assist detects strong crosswind
gusts that can impair the road holding of your
vehicle when driving straight ahead. Crosswind
Assist intervenes depending on the direction
and strength of the crosswind.
A stabilizing brake application helps you to keep
the vehicle on track.
Information appears in the instrument cluster In the event that Crosswind Assist intervenes
noticeably.
On vehicles without steering wheel buttons:
the d indicator lamp in the instrument clus-
ter flashes.
On vehicles with steering wheel buttons: the
d indicator lamp in the instrument cluster
flashes and the message Crosswind Assist
Activeappears in the multifunction display.
Crosswind Assist is active above a vehicle speed
of 50 mph (80 km/h) when the vehicle is driving
straight ahead or cornering gently.

LOW RANGE transmission ratio
General notes
The LOW RANGE transmission ratio assists you
when driving on difficult terrain. If you engage
LOW RANGE, the engine's performance charac-
teristics and the automatic transmission's shift-
ing characteristics are adjusted accordingly.
The transmission ratio from the engine to the
wheels is around 40% lower than in the on-road position. This increases the drive torque.

ence values for monitoring. In most cases, the tire pressure monitor detects
the new reference values automatically, e.g.
after you have:
Rchanged the tire pressure
Rchanged wheels or tires
Rinstalled new wheels or tires
However, you can also define reference values
manually as described here.
Before restarting the tire pressure monitor:
XSet the tire pressure to the value recommen- ded on the Tire and Loading Information plac-
ard or the tire pressure table on the B-pillar on
the driver's side (
Ypage 250).

In addition to the load-bearing index, load rat-
ing:may be imprinted after the letters that
identify speed rating on the sidewall of the tire
(
Ypage 261).
RIf no specification is given: no text (as in the
example above), represents a standard load
(SL) tire
RXL or Extra Load: represents a reinforced tire
RLight Load: represents a light load tire
RC, D, E: represents a load range that depends
on the maximum load that the tire can carry at
a certain pressure
iTire data is vehicle-specific and may deviate
from the data in the example.
Maximum tire load
Maximum tire load :is the maximum permis-
sible weight for which the tire is approved.
Do not overload the tires by exceeding the
specified load limit. The maximum permissible
load can be found on the vehicle's Tire and Loading Information placard on the B-pillar on
the driver's side (
Ypage 258).
iThe actual values for tires are specific to
each vehicle and may deviate from the values
in the illustration.
DOT, Tire Identification Number (TIN)
U.S. tire regulations stipulate that every tire
manufacturer or retreader must imprint a TIN in
or on the sidewall of each tire produced.
The TIN is a unique identification number. The
TIN enables the tire manufacturers or retreaders
to inform purchasers of recalls and other safety-
relevant matters. It makes it possible for the
purchaser to easily identify the affected tires.
The TIN is made up of manufacturer identifica-
tion code ;, tire size =, tire type code ?and
manufacturing date A.
DOT (Department of Transportation): tire
symbol :indicates that the tire complies with
the requirements of the U.S. Department of
Transportation.
Manufacturer identification code: manufac-
turer identification code ;provides details on
the tire manufacturer. New tires have a code
with two symbols. Retreaded tires have a code
with four symbols.
Further information about retreaded tires
(
Ypage 247).
Tire size: identifier=describes the tire size.
Tire type code: tire type code?can be used by
the manufacturer as a code to describe specific
characteristics of the tire.
Date of manufacture: date of manufactureA
provides information about the age of a tire. The first and second positions represent the week of
manufacture, starting with "01" for the first cal-
endar week. Positions three and four represent
the year of manufacture. For example, a tire that
