Fault in the automatic gearbox
A fault in the automatic gearbox can, for example, be noticeable by the follow-
ing.
› Only certain gears are selected.
› The reverse gear
R cannot be used.
› Shifting gears in Tiptronic mode is not possible.
CAUTION
If an error occurs on the automatic transmission the help of a specialist firm
should be sought immediately - there is a risk of damaging the vehicle.
Selector lever lock
Read and observe
and on page 138 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 .
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.
Releasing selector lever from mode P or N (selector lever lock)
›
Press the brake pedal and the lock button at the same time in the direction
of

» Fig. 130 on page 138 .
Just depress the brake pedal, if you would like to change from the mode N to
D .
Defective selector lever lock If the selector lever lock is defective or its power supply is interrupted (e.g. dis-
charged vehicle battery, faulty fuse), the selector lever can no longer be moved
out of position P in the normal manner and the vehicle can no longer be driven.
The selector lever must be unlocked specially » page 212.
Note
If you want to move the selector lever from mode P to mode D or vice versa,
move the selector lever quickly. This prevents that you accidentally select
mode R or N.
Manual shifting of gears (Tiptronic)

139Starting-off and Driving
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 » page 135, Information on braking .■
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.

Stopping (while the car is moving)
›
Depress the brake pedal and bring the vehicle to a stop.
›
Keep holding the brake pedal until driving is resumed.
The selector lever position N does not have to be selected when stopping for a
short time, such as at a cross roads.
Kickdown
The kickdown function allows you to achieve the maximum acceleration of
your vehicle while driving.
When the accelerator pedal is fully depressed, the kickdown function is activa-
ted in any forward driving mode.
The gearbox shifts down one or more gears depending on the vehicle speed
and engine speed, and the vehicle accelerates.
The gearbox does not shift up into the highest gear until the engine has
reached its maximum revolutions for this gear range.
WARNINGRapid acceleration, particularly on slippery roads, can lead to loss of control
of the vehicle – risk of accident!Running in and economical driving
Introduction
This chapter contains information on the following subjects:
Driving in
140
Tips for economical driving
140
The fuel consumption, degree of pollution and vehicle wear depend on driving
style, road condition, weather conditions and the like.
Driving in
Driving in the engine
The engine has to be run in during the first 1 500 kilometres. During this peri-
od, the driving style decides on the quality of the driving-in process.
During the first 1 000 km we recommend not driving faster than 3/4 of the
maximum permissible engine speed, not to drive at full throttle and to dis-
pense with the trailer.
In the area of 1,000 to 1,500 kilometres the engine load can be increased up
to the maximum permitted engine speed.
New tyres
New tyres must firstly be “run in”, as they do not offer optimal grip at first.
Therefore, drive especially carefully for the first 500 km or so.
New brake pads
New brake pads have to first “grind in” because these do not initially have the
best possible braking effect.
Therefore, drive especially carefully for the first 200 km or so.
Tips for economical driving
To achieve the lowest possible fuel consumption, the following instructions
must be observed.
Looking ahead when driving
Avoid unnecessary acceleration and braking.
Switch in an energy saving and timely manner Observe the recommended gear » page 43.
140Driving
Avoid full throttle and high speeds
Fuel consumption will be halved if only three-quarters of the possible top
speed of your vehicle is used.
Reducing idling
When the engine is switched off, such as when waiting in a traffic jam, the fuel economy is already greater after 30 - 40 s than the fuel quantity which is re-
quired for engine re-start.
Avoid short distances
When driving a short distance of less than about 4 km, the engine cannot
reach its operating temperature. As long as the engine has not reached oper-
ating temperature, the fuel consumption is significantly higher than with the
engine hot.
Pay attention to the correct tyre inflation pressure being maintained
Further information » page 191.
Avoid unnecessary ballast
Per 100 kg of weight, consumption increases by about 1 l/100 km. At a speed of
100 - 120 km/h, a vehicle fitted with a roof rack cross member without a load
will use about 10 % more fuel than normal due to the increased aerodynamic
drag.
Saving electricity
Electrical consumers (e.g. seat heating, air conditioning and the like) only turn
on for as long as necessary.
Driving through water and driving off of made-up roads
Introduction
This chapter contains information on the following subjects:
Driving through water
141
Driving off paved roads
142WARNINGImmediately after driving through water, mud, slush and the like, braking
effectiveness will be temporarily impaired » page 135, Information on brak-
ing . For this reason, sudden and violent braking manoeuvres are to be
avoided - there is a risk of accident!Driving through waterFig. 132
Maximum permissible water lev-
el when driving through water
Read and observe on page 141 first.
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 reach above the web of the lower beam » Fig. 132.
›
Do not drive any faster than at a walking speed.
At a higher speed, a water wave can form in front of the vehicle which can
cause water to penetrate into the air induction system of the engine or into
other parts of the vehicle.
›
Never stop in the water, do not reverse and do not switch the engine off.
CAUTION
■ Should water penetrate into the intake system of the engine, there is a
threat of serious damage being incurred by the engine parts!■
When driving through water, some vehicle parts such as chassis, electrics or
transmission can be severely damaged.
■
Oncoming vehicles can generate water waves which can exceed the permis-
sible water level for your vehicle.
■
Potholes, mud or rocks can be hidden under the water, making it difficult or
impossible to drive through the body of water.
■
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.
141Starting-off and Driving
Driving off paved roadsRead and observe
on page 141 first.
Only drive on such roads and in such terrain, which match the vehicle parame-ters » page 222 , Technical data as well as your driving skills.
The driver is always responsible for deciding whether the vehicle can handle
travelling in the given terrain.
When travelling off paved roads, we recommend activating the OFF ROAD
mode » page 144 .
WARNINGDrive particularly aware and pro-actively outside paved roads.■Always adjust your driving to the current terrain and weather conditions.
Excessive speed or incorrect driving manoeuvres can cause damage to the
vehicle and lead to serious injuries.■
Objects trapped under the floor of the vehicle can damage the fuel lines,
the brake system, the seals and other parts of the chassis. Check the un-
derside of the vehicle and remove the trapped objects.
■
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 chassis and its compo-
nents can get damaged.■
Drive slowly in unknown terrain and watch out for unexpected obstacles,
such as potholes, rocks, stumps, etc.
■
Check up on confusing sections of unpaved roads before travelling on them
and consider whether such travelling is possible without risk.

Note
If the engine stalls while driving and is started again within 30 seconds, then
OFF ROAD mode will be automatically activated.
Hill Descent Assistant
Read and observe
and on page 145 first.
The hill descent assistant (hereinafter referred to as assistant), with its auto-
matic braking action on all wheels, ensures a constant speed on a steep slope
when driving forwards and reversing.
The assistant is automatically engaged under the following conditions. The vehicle engine is running. 1st, 2nd or 3rd gear, reverse gear or no gear
is engaged and the selector lever is in position R, N, D, S or Tiptronic.
The downhill gradient is at least 10 % (when driving over sleepers, the lim-
it can briefly drop to 8 %).
Neither the accelerator nor the brake pedal is operated.
During an intervention of the Assistants, the warning light flashes in the in-
strument cluster.
The assistant holds the vehicle speed at which the vehicle was travelling when
it entered the slope.
By pressing the accelerator or brake pedal, the speed can be increased or re-
duced. This is true even if the shift lever is in the neutral position and the se-
lector lever in the N position. The engagement of the assistant is resumed af-
ter the pedal is released.
145Assist systems
For vehicles with manual transmission, the speed is maintained as follows.
› 1 gear - approx. 8 1)
- 30 km/h
› 2 gear - approx. 13 1 )
- 30 km/h
› 3 gear - approx. 22 1 )
- 30 km/h
› Reverse gear - approx. 9 1 )
- 30 km/h
› Neutral for driving forwards - as well as driving backwards - approx. 2 - 30
km/h
On vehicles with automatic transmission, the speed is maintained as follows.
› Position D, S, R or Tiptronic (for 1st, 2nd or 3rd gear) - approx. 2 - 30 km / h;
› Neutral for driving forwards - as well as reversing - approx. 2 - 30 km/hWARNINGFor the correct operation of the assistant the road surface must be suffi-
ciently adherent. The assistant cannot properly fulfil its function on slushy
soil due to physical reasons (e.g. ice or mud). - there is a risk of an accident!
Note
During an active intervention of the assistant, the brake lights do not light up.
TCSOFF ROAD
Read and observe
and on page 145 first.
The ASR OFF ROAD makes starting and driving on an unpaved surface easier
as it partially allows wheel-spin.
Note
When disabled, the TCS » Fig. 133 on page 143 OFF ROAD mode works without
the support of the TCS OFF ROAD.
EDS OFF ROAD
Read and observe
and on page 145 first.
The EDS supports OFF ROAD vehicle traction when driving on a surface withdifferent grip under the drive wheels or when driving over bumps.
A spinning wheel or wheels are braked earlier and with more force than with
the intervention of the standard EDS system.
ABS OFF ROAD
Read and observe
and on page 145 first.
The ABS OFF ROAD supports the driver when braking on an unpaved surface
such as gravel, snow, etc.
The system generated by a controlled locking of the wheels braked wheel be-
fore a “wedge” of piled material, which shortens the braking distance.
The system is only available, if the front wheels are in the straight-ahead posi-
tion.
The system operates at speeds of up to 50 km/h.
Start-Off Assistant 2)
Read and observe
and on page 145 first.
The Start-Off assistant assists the driver when setting off, such as on a steep
slope or on a slippery surface. When the driver presses the accelerator, the
maximum engine speed is electronically limited so that a gentle approach is
possible.

Operating Description
154
The Cruise Control System (CCS) maintains a set speed without you having to
actuate the accelerator pedal.
The state where the GRA maintains the speed is referred to hereinafter as the
control .
WARNING■
The GRA only serves to support and does not relieve the driver of the re-
sponsibility for the vehicle operation.■
Always adjust the speed and driving style to the current visibility, weath-
er, road and traffic conditions.
Functioning
Read and observe
on page 154 first.
Basic requirements for start of control The GRA is activated.
On vehicles with a manual transmission , the second gear or higher must
be engaged.
On vehicles with an automatic gearbox, the selector lever must be in the
D or S position, or in the Tiptronic position.
The current speed must be higher than 20 km/hr.
This is only possible within the range which is permitted by the power output and braking power of the engine.
WARNINGIf the engine power and engine braking effect is insufficient to maintain
the set speed, vehicle operation must be taken over!

The START-STOP system (hereinafter referred to as the system) saves fuel and
reduces polluting emissions and CO 2 emissions by turning the engine off, e.g.
when stopping at traffic lights, and starting the engine again when moving off.
WARNING■ Never let the vehicle roll with the engine switched off.■The brake servo unit and power steering only operate if the engine is run-
ning.
Operating conditions of the system
Fig. 144
Maxi DOT display: Engine is auto-
matically switched off / automat-
ic engine cut off is not possible
Read and observe on page 155 first.
For system-dependent automatic engine shutdown
to work, the following conditions must be met.
The driver's door is closed.
The driver has fastened the seat belt.
The bonnet is closed.
The driving speed was higher than 4 km.h after the last stop.
No trailer is coupled.
Some additional conditions for the system to function correctly cannot be in-
fluenced or recognised by the driver. Therefore, the system can react differ-
ently in situations which are identical from the driver's perspective.
If after stopping the car, the message START-STOP NOT POSSIBLE appears in
the segment display or the
» Fig. 144 check mark appears in the MAXI DOT
display, then the conditions for automatic engine shutdown are not met.
Running the engine is essential for the following reasons, for example.
› 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 capacity (high fan speed, big difference be-
tween the desired and actual interior temperature).
