Requirements for the system to function correctly
The following conditions must be met for the system to function correctly.
The driver's door is closed.
The driver has fastened the seat belt.
The driving speed was higher than 4 km.h after the last stop.
No trailer or other accessory is connected to the trailer socket.
System status
The system status is indicated in the instrument cluster display when stopped.
The engine is automatically switched off; when the vehicle moves off the igni-
tion process will be automatically initiated.
» Fig. 123START-STOP ACTIVE
The engine is not automatically switched off.
» Fig. 123
START-STOP NOT POSSIBLE
The engine does not shut down when the vehicle stops, if e.g. the following
applies.
▶ The engine temperature for the proper function of the system has not yet
been reached.
▶ The charge state of the vehicle battery is too low.
▶ The current consumption is too high.
▶ High air conditioning or heating output (high fan speed, big difference be-
tween the desired and actual interior temperature).
If the engine has shut down automatically but the system detects that the en- gine is required to run (e.g. if the brake pedal is pressed repeatedly) then the
system automatically starts up the engine.
If there is a system fault , the following message will appear in the display of
the instrument cluster. Seek help from a specialist garage.
Note■ If the driver's seat belt is removed for more than 30 seconds or the driver's
door is opened after the engine has switched off automatically, the engine will
have to be restarted manually.■
No automatic engine shut-down takes place when a vehicle with automatic
transmission is moving at low speed (e.g. during a traffic jam) and remains sta-
tionary after pressing the brake pedal lightly. Automatic engine shutdown
takes place if you press the brake pedal down with more force.
■
For vehicles with automatic transmission there is no automatic engine shut-
down when the system detects a manoeuvring action due to a large steering
angle.

Shift lock button
Read and observe and on page 106 first.
The selector lever is locked in mode P and N to prevent that the forward driv-
ing is selected accidentally, thereby setting the vehicle in motion.
The selector lever is locked only when the vehicle is stationary and at speeds
up to 5 km/h.
The selector lever lock is indicated by the illumination of the warning light .

» Fig. 128 .
To move the selector lever from mode N to D only the brake pedal must be
pressed.
The selector lever is not locked when quickly moving across the position N
(e.g. from R to D). This, for example, helps to rock out a vehicle that is stuck,
e.g. in a bank of snow. The selector lever lock will engage if the lever is in posi-
tion N for more than approx. 2 seconds without the brake pedal being de-
pressed.
If it is not possible to release the gear selector from mode P in the usual man-
ner, then this can be emergency unlocked » page 166.
DSNoteTo switch the selector lever from mode P to mode D/S or vice versa, move the
selector lever quickly. This prevents that you accidentally select mode R or N.
Manual shifting (Tiptronic)

The currently selected gear is indicated in the display » Fig. 127 on page 106 .
The gearshift indicator should be observed when changing gear » page 39.
When accelerating, the gearbox automatically shifts up into the higher gear
just before the maximum permissible engine speed is reached. If a lower gear
is selected, the gearbox does not shift down until there is no risk of the engine
overrevving.
Note
It may be beneficial, for example, when travelling downhill, to use manual
shifting of gears. Shifting to a lower gear reduces the load on the brakes and
hence the wear of the brakes.107Starting-off and Driving

Running in the engine
During the first 1 500 km, the driving style is decisive for successful the run-
ning in process is.
During the first 1 000 km , the engine should not be charged with more than
3/4 of the maximum permitted engine revs and without the trailer.
From about 1 000 to 1 500 km , the engine can be pushed up to the maximum
permitted engine speed.
Tips on economical driving
Fuel consumption depends on the driving style, road and weather conditions,
and similar such factors.
For an economical driving style, the following instructions must be observed. ▶ Avoid unnecessary acceleration and braking.
▶ Engage the recommended gear » page 39.
▶ Avoid full throttle and high speeds.
▶ Reduce idling.
▶ Avoid short distances.
▶ Ensure the correct tyre inflation pressure is maintained » page 151.
▶ Avoid unnecessary ballast.
▶ Remove the roof rack before driving if it is not needed.
▶ Only turn on electrical consumers (e.g. seat heating) for as long as necessary.
▶ Briefly ventilate before turning on the cooling system, do not use the cooling
system with the windows open.
▶ Do not leave windows open at high speeds.

109
Driving Tips
Only drive on roads and terrain that are appropriate to the vehicle parameters
» page 175 , Technical data .
The driver is always responsible for deciding whether the vehicle can cope
with the conditions and the terrain.
When travelling off paved roads, we recommend activating the OFF ROAD
mode » page 112 .
WARNING■
Adjust the speed and driving style to the current visibility, weather, road
and traffic conditions. Too high a speed or an erroneous manoeuvre may
cause serious injury and damage to the vehicle.■
Combustible objects such as dry leaves or twigs caught under the base of
the vehicle could ignite on hot vehicle parts - risk of fire!
CAUTION
■ Pay attention to the ground clearance of the vehicle! When driving over ob-
jects which are larger than the ground clearance, the vehicle can get damaged.■
Any objects that get trapped under the vehicle floor must be removed as
soon as possible. These items can cause damage to the vehicle (e.g. to parts of
the fuel or brake system).
Driving through waterFig. 130
Maximum permissible water lev-
el when driving through water
The following must be observed to avoid damage to the vehicle when driving
through bodies of water (e.g. flooded roads).
›
Therefore determine the depth of the water before driving through bodies of
water. The water level must not go above the web of the lower beam
» Fig. 130 .
›
Drive at no more than walking pace, otherwise a wave may form in front of
the vehicle, which could cause the water to enter into the vehicle’s systems
(e.g. the air intake system for the engine).
›
Never stop in the water, do not reverse and do not switch the engine off.
CAUTION
■ If water gets into the vehicle’s systems (e.g. the air intake system for the en-
gine) it can cause serious damage to the vehicle!■
Oncoming vehicles can generate water waves which can exceed the permis-
sible water level for your vehicle.
■
Do not drive through salt water, as the salt can cause corrosion. An vehicle
coming into contact with salt water is to be thoroughly rinsed with fresh wa-
ter.

Operation
121
Operation description
122The Cruise Control System (CCS) maintains a set speed without you having to
actuate the accelerator pedal. The state where the CCS maintains the speed is
referred to hereinafter as the control.WARNINGThe general information relating to the use of assistance systems must be
observed » page 110, in section General information .
Operation
Read and observe
on page 121 first.
Basic requirements for start of control The CCS is activated.
On vehicles with a manual transmission , the second gear or higher is en-
gaged.
On vehicles with an automatic transmission , the selector lever is in the
D/S position or in the Tiptronic position.
The current speed is higher than 20 km/h.
This, however, is only possible to the extent permitted by the engine output
and braking power of the vehicle.
WARNINGIf the engine output or engine braking effect is insufficient to maintain the
set speed, the driver must assume control of the accelerator and brake
pedals!121Assist systems
