Special characteristics of alternating-
code radio systems
If the system cannot be operated after repeated
programming, check whether the system to be
operated uses an alternating-code system.
Read the operating instructions of the system or
press and hold the programmed button on the
interior rearview mirror. If the LED on the interior
rearview mirror flashes rapidly at first and then
lights up continuously for 2 seconds, the system
is equipped with an alternating-code system.
This flashing LED pattern repeats itself for ap‐
prox. 20 seconds.
In systems with an alternating-code system, the
Universal Garage Door Opener and the system
must be additionally synchronized.
Please obtain additional information on syn‐
chronization in the operating instructions of the
system being set up.
The systems will be easier to synchronize with
the aid of a second person.
Synchronization:1.Park the vehicle within range of the remote-
controlled system.2.Program the corresponding button on the
interior rearview mirror as described.3.Identify and press the synchronization but‐
ton on the system being set up. You have
approx. 30 seconds for the next step.4.Press and hold the button on the interior
rearview mirror for approx. 3 seconds and
then release it. Repeat this step up to three
times if necessary to complete the synchro‐
nization procedure. When synchronization
is completed, the programmed function is
executed.

Ensure that the floor mats are securely fastened
again when they are returned after being re‐
moved, such as for cleaning.◀
Driving in wet conditions
When roads are wet or there is heavy rain, briefly
exert gentle pressure on the brake pedal every
few miles.
Ensure that this action does not endanger other
road users.
The heat generated in this process helps dry the
brake discs and pads.
In this way braking efficiency will be available
when you need it.
Hills
Drive long or steep downhill gradients in the gear
in which the least braking is required. Otherwise,
the brake system may overheat, resulting in a
reduction in the brake system efficiency.
You can increase the engine's braking effect by
shifting down, going all the way to first gear, if
necessary.
Downshifting in manual mode of the 8-gear
Sport automatic transmission, refer to page 54.
Downshifting in manual mode of the 7-gear
Sport automatic transmission with dual clutch,
refer to page 57.
Avoid load on the brakes
Avoid placing excessive load on the brake
system. Light but consistent brake pressure can
lead to high temperatures, brake wear and pos‐
sibly even brake failure.◀
Do not drive in neutral
Never drive with the transmission in neu‐
tral, with the engine switched off or with the
clutch depressed; otherwise, you will have nei‐
ther the braking action of the engine or nor its
power assistance when braking or steering.◀Brake disc corrosion
Corrosion on the brake discs and contamination
on the brake pads are furthered by:▷Low mileage.▷Extended periods when the vehicle is not
used at all.▷Infrequent use of the brakes.
Corrosion occurs when the minimum pressure
that must be exerted by the pads during brake
applications to clean the discs is not reached.
Should corrosion form on the brake discs, the
brakes will tend to respond with a pulsating ef‐
fect that generally cannot be corrected.
Condensation under the parked vehicle
When using the automatic climate control, con‐
densation water develops that exits underneath
the vehicle.
Therefore, traces of condensed water under the
vehicle are normal.
Loading Overloading the vehicle
To avoid exceeding the approved carrying
capacity of the tires, never overload the vehicle.
Overloading can lead to overheating and in‐
creases the rate at which damage develops in‐
side the tires. This could result in a sudden loss
of tire inflation pressure.◀
Secure heavy objects
Never transport unsecured heavy or hard
objects in the passenger compartment, as they
could be thrown around and pose a safety haz‐
ard to the vehicle's occupants during abrupt
braking or evasive maneuvers.◀
No fluids in the cargo area
Make sure that fluids do not leak into the
cargo area; otherwise, the vehicle may be dam‐
aged.◀

Saving fuel
General information
Your vehicle contains advanced technology for
the reduction of fuel consumption and emis‐
sions.
Fuel consumption depends on a number of dif‐
ferent factors.
The implementation of certain measures, driv‐
ing style and regular maintenance, refer to
page 168, can have an influence on fuel con‐
sumption and on the environmental impact.
Remove unnecessary cargo
Additional weight increases fuel consumption.
Remove attached parts following use
Remove auxiliary mirrors or rear-mounted lug‐
gage racks after use.
Attached parts on the vehicle impair the aero‐
dynamics and increase the fuel consumption.
