The tyre pressures should always be checked
when the tyres are cold.
Do not use winter tyres all through the year; they
will increase fuel consumption by up to 10 %.
Avoid carrying unnecessary loads
Every kilo of extra weight will increase the fuel
consumption, so it is worth checking the luggage
compartment occasionally to make sure that no
unnecessary loads are being transported.
Save electrical energy
The engine drives the alternator to generate elec
tricity. This means that fuel consumption rises
when more power is required for electrical equip
ment. Switch off electrical equipment when it is
not needed. Electrical equipment which uses a
lot of electricity includes the blower (at a high
setting), the rear window heating and the seat
heating*.

CD CAUTION
If the engine has been working hard for a long
time, there is a risk of heat building up in the
engine compartment after the engine has
been switched off; this could cause engine
damage. For this reason, you should leave the
engine idling for about 2 minutes before
switching it off.
{(D Note
After the engine is stopped, the radiator fan
may remain on or turn itself back on for up to
10 minutes, even if the ignition is switched
off. This may occur for the following reasons:
- Residual heat has raised the coolant tem-
perature.
- Direct sunlight has additionally heated up
the engine compartment while the engine is
warm.
-Applies to vehicles with diesel particulate
filter: The emission control system is hot
because of the regeneration process, even

WARNING
- Never press the accelerator pedal or release
the clutch inadvertently if a gear is engaged
or if the selector lever is not in position P or
N (on automatic vehicles) while the vehicle
is stationary with the engine running. The
vehicle will otherwise start moving immedi
ately and could cause an accident.
- You should only use the emergency braking
function in a real emergency, for example if
the brake system were to fail or if the brake
pedal were to be obstructed. If you use the
emergency braking function by activating
the parking brake switch, this has the same
effect as heavy braking. Please remember
that the ESC (and the integrated ABS, EDL
and traction control functions) is still sub
ject to certain physical limits. In a corner or
in bad road or weather conditions an emer
gency stop can cause the vehicle to skid or
lose steering control.
- It is not possible to apply the parking brake
if the electrical power supply fails. In this
case, park the vehicle on a level surface and
select 1st gear (manual gearbox) or move
the selector lever to position P (automatic
gearbox) to prevent it from rolling. Obtain
professional assistance.
- Always take the key with you when leaving
your vehicle -even if you only intend to be
gone for a short time. This is especially im
portant if children are left in the car. They
might otherwise be able to start the engine,
release the parking brake or use power-op
erated equipment such as the electric win
dows -this could lead to injuries.
- Do not leave anyone (especially children) in
the vehicle when it is locked. Locked doors
could delay assistance in an emergency, po
tentially putting lives at risk.
Applies to: vehicles with automatic gearbox
You can apply the parking brake manually or
switch on the hold assist* when stopping at
traffic lights, etc. You do not then have to
hold the car with the brake pedal, as the Driving
brakes will stop it creeping forward while a
gear is engaged in the automatic transmis
sion. When you drive off in the normal way,
the parking brake will be released automati
cally and your vehicle will start moving
¢page 75.
(CD) Note
- Any slight noise which may be heard when
the parking brake is applied or released is
quite normal and no cause for concern.
- The parking brake runs an automatic test
cycle at regular intervals when the vehicle is
parked. This may cause a slight noise, which
is normal.
- If the electrical power supply fails, it is not
possible to release the parking brake (if it
was applied) or to apply the parking brake
(if it was released) ¢ &,. Obtain professional
assistance.
Moving off
Various features and safety functions are availa
ble for driving off, depending on the equipment
in your vehicle.
Hill starting with the parking brake applied
Important: The driver's door must be closed.
� To drive off more easily on a slope, apply the
parking brake and drive off just as you usually
would. The parking brake will be released auto
matically, but not until there is enough power
at the wheels to make the vehicle move in the
desired direction.
Hill starting with the hill hold assist
The hill hold assist function makes it easier to
drive away on a slope.
Important: The driver's door must be closed and
the engine must be running.
� To activate the hill hold assist, press and hold
the brake pedal for several seconds. The vehicle
must be on a slope and facing uphill.
When you release the brake pedal the braking
force will be maintained for a moment ¢.&. in

order to hold the vehicle and make it easier for
you to drive away.
Driving off with the hold assist
Applies to: vehicles with hold assist
The hold assist helps the driver if the vehicle is
stationary for a long period or very often, for in
stance at traffic lights, on steep gradients or in
stop-and-go traffic.
Important: The driver's door must be closed and
the engine must be running.
.,. To switch the hold assist on/off, press the but
ton(@) @¢page 74, Fig. 78, ¢A .The LED in
the button will light up or go out.
.,. Once it detects that the vehicle has stopped,
the hold assist keeps the vehicle stationary.
You can now take your foot off the brake pedal.
.,. Drive
off in the normal way: the brake will be
released automatically and the vehicle will
start moving.
In certain situations, the hold assist transfers the
job of holding the vehicle to the parking brake.
As soon as the parking brake is holding the vehi
cle still, the warning lamp. appears in the in
strument cluster. In addition, the LED in the C®)
button will light up.
Driver messages in the instrument cluster
display
[iJ Hold assist: unavailable
If this message appears, the system require
ments have not been met.
A WARNING
Applies to: vehicles with hill hold assist
If you do not drive away immediately after re
leasing the brake pedal, or if the engine
stalls, the vehicle may start to roll back. You
should therefore immediately press the brake
pedal or apply the parking brake.
A WARNING
The intelligent technology in the hold assist*
and hill hold assist functions cannot defy the
laws of physics. Do not let the extra conven
ience afforded by the hold assist* and hill
76 hold
assist functions tempt you into taking
any risks when driving -this can cause acci
dents.
- The hold assist* and hill hold assist func
tions cannot keep the vehicle stationary in
all conditions on a gradient (e.g. if the road
is slippery or icy).
- Always ensure that the vehicle is stopped
properly and safely -risk of accident!
CD CAUTION
Switch off the hold assist* function before
driving the vehicle into a car wash.
� Note
Applies to: vehicles with automatic gearbox
When the hold assist* function is switched
on, it stops the vehicle from creeping for
wards when you take your foot off the brake
pedal.
Automatic gearbox
Introduction
Applies to: vehicles with automatic gearbox
The vehicle is equipped with an electronically
controlled dual-clutch gearbox (S tronic). Torque
between the engine and the gearbox is transmit
ted via two independent clutches. They enable
smooth, uninterrupted acceleration of the vehi
cle.
The gearbox shifts up or down automatically and
continuously adapts the timing of the gear
changes to your driving style.
When you drive at moderate speeds the gearbox
will select the most economical shift pro
gramme. It will then change up early and delay
the downshifts to give better fuel economy.
If you drive at higher speeds with heavy accelera
tion, if you open the throttle quickly, or if you use
the kick-down or the car's maximum speed, the
gearbox will automatically select the more "spor
ty" shift programmes.
If desired, you can also select the gears manually
(tiptronic mode).
Downloaded from www.Manualslib.com manuals search engine Driving
fully interrupted even when the engine is
idling.
- The accelerator pedal must on no account
be pressed inadvertently when the vehicle is
stationary. The vehicle could otherwise start
moving immediately (in some cases even if
the parking brake is engaged) and possibly
cause an accident.
- Do not press the accelerator while selecting
a gear with the vehicle stationary and the
engine running, as this could cause an acci
dent.
- Never move the selector lever to R or P
when driving at normal speeds, as this could
cause an accident.
- Before you drive down a steep gradient, re
duce the speed and use "tiptronic" to select
a low gear.
- Never allow the brake to drag when driving
downhill and do not use the brake pedal too
often or for long periods. Constant braking
will cause the brakes to overheat and will
considerably reduce the effectiveness of the
brakes. It will increase the braking distance
and could cause the brake system to fail.
- To avoid rolling back on gradients always
hold the vehicle with the footbrake or park
ing brake if you have to stop.
- Never attempt to hold the vehicle with the
clutch when stopping on a gradient. The
clutch is disengaged automatically if it is
overloaded and becomes too hot -accident
risk! If the clutch is overloaded, the indica
tor lamp 51 will light up and a message will
appear ¢page 83.
CD CAUTION
- When you have stopped on a gradient, do
not try to stop the vehicle rolling back by ac
celerating when a gear is engaged. This
could cause the automatic gearbox to over
heat and become damaged. Apply the park
ing brake or press the brake pedal in order
to prevent the vehicle from rolling back.
- If you allow the car to roll with the selector
lever in position N with the engine switched
off, the automatic gearbox will be damaged
as it will not be lubricated.
80 -
In certain driving and traffic conditions, for
instance in stop-and-go traffic, if you have
to pull away frequently or if the vehicle
creeps forwards over a long distance, the
gearbox can overheat and become dam
aged. If the indicator lamp 51 or the warn
ing lamp . lights up, stop the vehicle at
the first opportunity and let the gearbox
cool down ¢page 83.
- If you allow the car to roll with the engine
switched off, the S tronic gearbox will be
damaged as it will not be lubricated
¢ page 2 78, Tow-starting I towing away.
ijJ) Note
For safety reasons the parking brake will only
release automatically if the driver's seat belt
is engaged in its buckle.
Downhill speed control
Applies to: vehicles with automatic gearbox
The downhill speed control function helps the
driver when driving down steep gradients.
Downhill speed control is activated on a downhill
gradient when the selector lever is in D/S and the
driver presses the brake pedal. The gearbox auto
matically selects a suitable gear for the gradient.
The downhill speed control function attempts to
maintain the speed at which the vehicle was trav
elling when the foot brake was applied (subject
to the laws of physics and technical limitations of
the power train). It may be necessary to adjust
the speed again using the foot brake. The down
hill speed control can change down to 3rd gear
but no further, so it may be necessary to change
to tiptronic mode on very steep gradients. In this
case, change down manually to 2nd or 1st gear in
tiptronic mode to use the engine braking effect
and reduce the load on the brakes.
Downhill speed control is deactivated as soon as
the road levels out again or you press the acceler
ator pedal.
On vehicles with cruise control system*
¢ page 86, downhill speed control is activated
when you set a cruising speed.
