Avoid driving short distances Short distances result in an above-average high fuel consumption.– Avoid driving a distance of no more
than 4 km if the engine is cold.
The engine and catalytic converter mu
st first have reached their optimal
operating
temperature
in order to effectively reduce fuel consumption and pollutant emissions.
The cold engine vehicle consumes approx. 15 - 20 litres/100 km of fuel immediately after starting. Fuel consumption drops to 10
litres/100 km after just 1 kilometre. The
engine reaches its operating temperat
ure (outside temperature and engine
dependent) only after about
4 to 10
kilometres and the fuel
consumption then stabi-
lizes. You should therefore avoid driving short distances whenever possible. An important factor in this connection is also the
ambient temperature
⇒fig. 161
. It
shows the fuel consumption after driving a
certain distance, on the one hand at a
temperature of +20°C and on the other hand
at a temperature of -10°C. Your vehicle
has a higher fuel consumption in winter than in summer.Checking tyre inflation pressures Tyres which are correctly inflated save fuel.Always ensure that your tyres are inflated to the correct pressure at all times. The rolling resistance will be increased if the tyre filling pressure is too low. This will not only increase fuel consumption but also tyre we
ar and the driving behaviour will worsen.
Always check the inflation pr
essure of the tyres when
cold
.
Do not drive with
winter tyres
all year round for this costs about 10 % more fuel. They
are also louder and have poorer handling
characteristics and higher wear at tempera-
tures more than 10°C.No unnecessary ballast Transporting ballast costs fuel.The fact that every kilogram of extra
weight
increases your fuel consumption means
that it is worth taking a look in the luggage compartment to avoid transporting any unnecessary ballast. It is particularly in town traffic, when on
e is accelerating quite often, that the vehicle
weight will have a significant effect upon th
e fuel consumption. A rule of thumb here
is that an increase in weight of 100 kilogr
ams will cause an increase in fuel consump-
tion of about 1 litre/100 kilometres. You may frequently also leave a
roof rack fitted
on just out of convenience, although
you no longer need it. The in
creased aerodynamic drag of yo
ur vehicle causes it to use
about 10% more fuel than normal at a speed of 100 - 120 km/h, even when you are not carrying a load on the roof.Saving electricity Generating electricity costs fuel.– Switch off electrical components as
soon as you no longer need them.
When the engine is running,
the alternator generates and
supplies electrical power.
The greater the load on the alternator as a result of having a large number of electrical components switched on, the more fuel
will be consumed for operating the
alternator.Keeping a log of your fuel consumptionIf you really wish to keep a close check on your
fuel consumption
, it is best to enter
the figures in a logbook. This does not take much time but is a very worthwhile exer- cise. It enables you to detect any change (p
ositive and negative) at an early stage and
to take any appropriate action.

Safe off-road drivingAdopt a correct seated position and always fa
sten the seat belt correctly. Make sure
that your front passenger and your passengers
seated on the rear seats always fasten
their seat belts correctly. When driving off-road, it is perhaps more useful to adopt a slightly different seated position. Depending on the terrain, an incr
eased force may be required to turn the
steering wheel because the force is transferred from the front wheels to the steering wheel. You must be seated in such a way that you have good front visibility, especially when driving uphill or dow
nhill. You must never be seat
ed in such a way that the
distance between your chest and the midd
le of the airbag cover is less than
25 cm
⇒ page 148. Under no circumstances must you drive off-ro
ad with high heels,
slippery or open
shoes. You should wear shoes which fit your fe
et well and allow you to get a feel for the
pedals.
WARNING
Observe the important guidelines
⇒page 180.
Before driving off-road•
Make sure the tyres are suitable for the planned off-road journey. Before you drive
through difficult terrai
n, equip your vehicle with off-road tyres.
•
Fill up your tank. The fuel consumption of
the vehicle is much higher when driving
off-road than when driving on the road.•
Install the towing eye at the front or at the rear before driving off-road. It is not
always possible to install the towing eye if the vehicle got stuck.•
Always check the inflation pressure of a
ll the tyres and if necessary correct it.
•
Check the vehicle tool kit and suppl
ement it according to your needs.
•
Fill with engine oil up to the line , so that the engine is sufficiently supplied with
engine oil when the vehicle is in a tilted position
⇒page 205, “Check engine oil level”.
•
Top up wash fluid.
•
Stow your load as low as possible in the vehicle and attach all the items which are
loose.Off-road driving•
Never be alone when driving off-road and be prepared to encounter unexpected
situations. Travel together with at least two off-road vehicles. Equipment with which you can call for help in an em
ergency is partic
ularly useful.
•
Drive slowly through unclear terrain.
•
You must stop when encountering difficul
t passages and explore the continuation
of the route on foot. If you cannot go on or
if you doubt the safety of the route, turn
back and choose another way.•
Drive slowly over hilltops. Make sure that
the wheels of the vehicle do not lift off
the ground, as this could severely damage
the vehicle and it may become disabled.
•
Drive slowly on difficult stretches of the route. When driving on a slippery ground,
shift up into the next higher gear and make
sure that the vehicle always stays in motion.
Do not drive too fast so that you don't lose control over your vehicle.•
If your vehicle got stuck in
sand, snow or sludge, it may be more effective to reverse
the vehicle than trying to drive forwards.•
Place stones, footmats or pieces of wood
under the spinning wheels in order to
achieve traction on a sandy or slippery ground.•
Do no drive through water before reading what you must take into account
⇒ page 179.•
Keep sufficient distance from other vehicles even at low speeds. When the first
vehicle suddenly gets stuck, the following vehi
cle can still stop in time without getting
stuck itself.•
Do not plan day trips which are too far in distance.
•
Do not use the cruise control system when
driving off-road. It is only intended for
driving on the road.
WARNING
•
The intelligent engineering of your ve
hicle cannot overco
me the physical
limits of your vehicle.

– Drive at walking speed over rocky passages. – If it is not possible to drive around a ston
e, gently drive onto
the stone with one of
the front wheels and then drive over it slowly.
WARNING
Observe the important guidelines
⇒page 180.
Caution
•
On no account drive over large objects (suc
h as pieces of rock
or tree stumps),
neither in the middle nor on one side. When driving over objects which are larger than the ground clearance, the chassis and its
components can get da
maged. Your vehicle
could break down far away from any assistance.•
Even objects that are smaller than the ex
isting ground clearance can come into
contact with the underbody of the vehicle an
d can lead to damage or failure of the
vehicle. This applies especially when there is
a hollow or soft ground in front or behind
the object or if you drive too fast over th
e object and thus the vehicle is deflected.
For the sake of the environment
Leaking engine oil and brake fluid pollute the environment and contaminate the bodies of water. The dispos
al e.g. of engine oil soaked soil can be costly.
Crossing bodies of waterParticular attention is required wh
en driving through bodies of water
⇒page 179.
Driving through snow-covered terrain– Before you drive through snow-covered te
rrain, mount snow chains on the front
wheels or on the rear wheels
⇒page 219, “Snow chains” in order to achieve the
best possible traction.
–Switch on the Off-road mode
⇒page 170.
Even harmless looking sections of terrain can be dangerous. This applies in particular for sections where no ruts or other tracks are visible.
WARNING
•
Driving through snow-covered terrain poses special dangers. Never choose
a dangerous route and never take a risk which could jeopardize your safety and that of your passengers. If you cannot go on or if you doubt the safety of the route, turn back and choose another way.•
Potholes, troughs, trenches, precipices,
sheets of ice or other obstructions
are often completely or partially obscured by snow.•
The hidden dangers of snow can cause an accident, serious injuries or your
vehicle to break down under
extreme weather conditions.
Driving over steep terrainDriving uphill and downhill– Stop the vehicle before driving uphill or
downhill, exit the vehicle and explore the
situation.
– Walk a stretch and check the firmness of the soil and look for obstructions or other
hidden dangers.
– Check how the route continues beyond the slope. – Switch on the Off-road mode
⇒page 170.
– Drive slowly and steadily straight uphill or downhill.– Do not stop the vehicle on a hillside or attempt to turn around. – You must prevent the engine from cutting out.Driving uphill– Check before driving over a hilltop, how it
continues on the other side. If you drive
up a steep hill, the vehicle faces the sky and you cannot see what is directly in front of the vehicle.
– Switch on the Off-road mode

– Do not shift gears or release the
clutch during th
e climbing phase.
– Depress the accelerator only as much as
is necessary in order
to handle the slope.
If you can go no further on a slope– Never attempt to make a turn with the vehicle on a hillside. – If the engine cuts out, press the foot brake and restart the engine. – Engage the reverse gear and carefully
drive backwards in your own tracks.
– Press the foot brake in order to maintain a constant speed.Driving downhill–Switch on the Off-road mode
⇒page 170.
– Shift into first gear or select the first driving stage, while in the Tiptronic mode, to
drive downhill on steep hillsides in order
to use the Downhill Drive Support to its
maximum.
– Press the foot brake gently, so you do not lose the control over your vehicle. – If it is feasible and safe, drive straight down (maximum gradient).– Do not release the clutch or shift into Neutral.
WARNING
•
Never attempt to drive uphill or downhill if it is too steep for your vehicle.
The vehicle could slip or roll
over - risk of accident!
•
Never attempt to make a turn on a hillside. The vehicle could tilt or roll over.
This can result in serious accidents.•
If the engine cuts out on a slope or
you can no longer go on for whatever
other reason, then stop!•
Never let the vehicle roll down the hill
side at idling speed. You can lose the
control over your vehicle.•
If the engine cuts out, press the foot brake and restart the engine. Engage the
reverse gear and carefully drive backward
s in your own tracks. Use the engine
braking power and press the foot brake in order to maintain a slow and constant speed.

Driving at an angle on a hillsideFig. 166 Steer and maintain your trajectory
/ in direction to exit - facing uphill
Driving at an angle on a hillside is one of the most dangerous situations while driving off-road. It may look harmle
ss, but you must never underestimate the difficulties and
the dangers when driving at an angle on a
hillside. Basically you should avoid moving
your vehicle into a sideways
position on a hillside. Unde
r certain circumstances, the
vehicle can slide away uncontrollably or roll over. Check before driving in a tilted position, whether there is a different and safer route. If you have to drive in a tilted position, then
the ground should be as firm and even as
possible. Note that the vehicle may slide sideways or sink in and roll over when driving on slippery or soft ground. Make sure that
the inclination is not too steep when driving
over surface irregularities. Otherwise, the vehicle can roll over and then roll down the hillside. If the vehicle is at a very steep angle, the wheels on the low side must not sink deeply into the ground or into troughs and you mu
st not drive over stones, tree stumps or
other obstructions with the alternate raised wheels. If there is a risk your ve
hicle may tilt, steer immedi
ately in direction of dip

– Check the tyres and the axles for damage and remove coarse dirt, stones and
foreign bodies from the tyre tread.
– Clean the turn signal lights, the headlights, the number plate and the windows. – Check the underbody of the vehicle and re
move trapped objects, such as scrub or
wood pieces.
– Contact your specialist gara
ge if you detect any damage.
– In case of thick layers of
dirt, clean the radiator grille, the engine compartment and
the underbody of the vehicle.
WARNING
•
Combustible materials which are trapped under the vehicle floor can be
dangerous. They can impair the driving
safety and the safety of all the occu-
pants of the vehicle. After driving off-
road, always check the underside of the
vehicle and remove trapped objects.•
Never continue the journey if objects
are trapped under the vehicle. This
can damage the fuel lines, the brake sy
stem, the seals and other parts of the
chassis.•
Combustible objects such as dry leaves or twigs could ignite on hot vehicle
parts. A vehicle fire can also lead to serious injuries.•

Note
•
We recommend that you also have your
vehicle inspected between service inter-
vals if you tow a trailer frequently.•
The handbrake on the towing vehicle must be put on when coupling and decou-
pling the trailer.Driving Tips Particular caution is required when towing a trailer.– Do not, as far as possible, drive with
your vehicle unladen and the trailer laden.
– Do not make full use of the legal maximum speeds. This applies in particular to
downhill sections.
– Apply the brakes in good time. – Keep a check on the coolant temperature gauge if the outside temperature is high. Distribution of weight The distribution of the weight
is very poor if your vehicle
is unladen and the trailer is
laden. Maintain a particularly low speed if you cannot avoid driving with this combina-tion. Driving speed Do not drive faster than 80 km/hour for safety reasons. This also applies for countries in which higher speeds are allowed.
The fact that the driving stability of the vehicle + trailer combination reduces with increasing speed means that the legally allowed speed should not be used when there are unfavourable road, weather or wind cond
itions, particularly near accident black
spots. You must always reduce your speed immediat
ely as soon as you detect even just the
slightest swaying
of the trailer. On no account attempt to stop the trailer from
“swaying” by accelerating. Apply the brakes in good time! If
the trailer is fitted with a
trailer brake
, apply the
brakes gently at first and then brake firmly. This will avoid brake jolts resulting from the trailer wheels locking. Shift down gears in good time before negotiating a downhill section to allow the engine to also act as a brake. Engine overheating Please keep a check on the coolant temperature gauge if you have to negotiate a lengthy slope in a low gear at a high engi
ne speed when the outside temperature is
very high
⇒page 17, “Coolant temperature gauge”.
If the needle of the coolant temperature gauge moves into the right-hand area or even the red area of the scale, reduce your speed immediately. Stop and switch off the engine if the warning light
in the instrument cluster begins flashing. Wait a few
minutes and check the level of coolant in the coolant expansion bottle
⇒page 207,
“Inspecting the coolant level”. Please refer to the following guidelines
⇒page 34, “Coolant temperature/ Coolant
quantity
”.
The coolant temperature can be reduced by switching on the heating.Any increase in the cooling effect of the coolant fan through shifting down a gear and increasing the engine speed is not possible
since the fan speed is independent of the
engine speed. One should also not drop a gear
for this reason when towing a trailer as
long as the engine can manage th
e slope without any drop in speed.
