Driving on flooded roads
!
Do not drive through flooded areas. Check
the depth of any water before driving
through it. Drive slowly through standing
water. Otherwise, water could enter the
vehicle interior or engine compartment. It
can then damage the engine's or automatic
transmission's electronic components. It
can also be sucked in by the engine's air
intake connection and cause engine dam-
age.
If you have to drive on stretches of road on
which water has collected, please bear in mind
that: R the water level of standing water should not
be above the lower edge of the front
bumper
R you must not drive faster than walking
speed Driving in winter
G
WARNING
If you shift down on a slippery road surface
in an attempt to increase the engine's brak-
ing effect, the drive wheels could lose their
grip. There is an increased danger of skid-
ding and accidents.
Do not shift down for additional engine brak-
ing on a slippery road surface.
! An accumulation of snow and ice, particu-
larly when frozen, caught in the area around
the air intake slots, moving parts, the axles
and the wheel arches may:
R restrict air intake
R damage vehicle parts
R cause malfunctions by restricting the
mobility intended by the design (e.g.
reduced possible steering input).
Regularly check the vehicle and remove
snow or ice when traveling in wintry condi-
tions.
If there is any damage, inform a qualified
specialist workshop.
! Vehicles with automatic transmission may
only briefly coast in neutral position N.
Extended coasting of the wheels, e.g. when
towing, results in transmission damage. Have your vehicle winterized at a qualified spe-
cialist workshop at the onset of winter.
Drive particularly carefully on slippery roads.
Avoid sudden acceleration, steering and brak-
ing maneuvers. Do not use cruise control.
If the vehicle threatens to skid or cannot be
stopped when moving at low speed:
X Shift the transmission to position i.
X Try to maintain control of the vehicle using
corrective steering.
The outside temperature indicator is not
designed to serve as an ice-warning device
and is therefore unsuitable for that purpose.
Changes in the outside temperature are dis-
played after a short delay.
Indicated temperatures just above the freezing
point do not guarantee that the road surface is
free of ice. The road may still be icy, especially
in wooded areas or on bridges. If you do not
adjust your driving style, the vehicle may start
to skid. Always adapt your driving style and
drive at a speed to suit the prevailing weather
conditions.
You should pay special attention to road con-
ditions when temperatures are around freezing
point.
You can find further information under:
R "M+S tires" ( Y page
280)
R "Snow chains" (Y page 281)
R "Driving with summer tires" (Y page 280)
Also observe the notes under "Winter opera-
tion" (Y page 280). Driving off-road
Important safety notes G
WARNING
If you drive on a steep incline at an angle or
turn when driving on an incline, the vehicle
could slip sideways, tip and rollover. There is
a risk of an accident.
Always drive on a steep incline in the line of
fall (straight up or down) and do not turn the
vehicle. 144
Driving tips
Driving and parking

R
Drive with extreme care over unknown ter-
rain where you can only see for a short dis-
tance. As a precaution, get out of the vehi-
cle to take a look at the route to be taken in
advance.
R Check the water depth before fording.
R Watch out for obstacles (e.g. rocks, holes,
tree stumps and ruts).
R Avoid edges where the surface could crum-
ble or break away.
Checklist after driving off-road !
If you detect damage to the vehicle after
driving off-road, have the vehicle checked
immediately at a qualified specialist work-
shop.
Off-road driving places a higher demand on
your vehicle than normal road operation.
Check your vehicle after driving on rough ter-
rain. By doing so you will notice any damage in
good time and reduce the risk of an accident
for yourself and other road users. Clean your
vehicle thoroughly before driving on public
roads.
Observe the following points after driving off-
road, on construction sites and before driving
on public roads:
X Activate ESP ®
(Y page 69).
X Clean the headlamps and tail lamps and
check them for damage.
X Clean the front and rear license plates.
X Clean the windshield, windows and exterior
mirrors.
X Clean the steps, door sills and grab handles.
This increases safety of footing.
X Clean the wheels/tires, wheel housings and
the underbody of the vehicle with a water
jet.
This increases road grip, especially on wet
road surfaces.
X Check the wheels/tires and wheel housings
for trapped foreign objects and remove
them.
Trapped foreign objects can damage the
wheels/tires and may be flung out from the
vehicle when you continue driving.
X Check the underbody for trapped branches
or other parts of plants and remove them.
Trapped branches or other parts of plants
increase the risk of fire and can cause dam- age to fuel lines, brake hoses and the rubber
bellows of axle joints and drive shafts.
X Clean the brake disks, brake pads and axle
joints, particularly after operation in sand,
mud, grit/gravel, water or similarly dirty
conditions.
X Check the entire floor assembly, the tires,
wheels, bodywork structure, brakes, steer-
ing, chassis and exhaust system for any
damage.
X Check the service brake for operating
safety, e.g. carry out a brake test.
X If you notice strong vibrations after driving
off-road, check the wheels and drive train
for foreign objects again. Remove any for-
eign objects which can lead to imbalances
and thus cause vibrations. Driving in mountainous areas
When driving in mountainous areas, note that
the power output of the engine, and with it its
gradient climbing capability, decrease with
increasing altitude. Please take note of this
particularly when driving with a trailer in moun-
tainous areas.
The maximum permissible trailer loads are
valid for journeys at altitudes up to

1100 yds
(1000 m) above sea level with gradients up to
12%.
Information on maximum permissible trailer
loads can be found in your vehicle registration
papers and on the vehicle identification plate
(Y page 304) or under "Trailer loads" ( Y page 315).
When driving at altitudes of 2700 yds
(2500 m) above sea level, the ECO start/stop
function is no longer available.
Notes on braking on downhill gradients can be
found in the "Braking" section (Y page 142). Driving systems
Cruise control
General notes Cruise control maintains the speed of the vehi-
cle for you. It brakes automatically in order to
avoid exceeding the set speed.146

assistance function of Active Parking Assist is
stopped. The vehicle is parked and kept sta-
tionary without the driver having to depress the brake pedal. The braking effect is canceled
when you depress the accelerator pedal.
Active Parking Assist no longer supports you
with steering interventions and brake applica-
tions. Once active parking assistance has been
stopped, you must steer and brake again your-
self. PARKTRONIC is still available.
Parking tips:
R The way your vehicle is positioned in the
parking space after parking is dependent on
various factors. These include the position
and shape of the vehicles parked in front
and behind it and the conditions of the loca-
tion. It may be the case that Active Parking
Assist guides you too far into a parking
space, or not far enough into it. In some
cases, it may also lead you across or onto
the curb. In this case, cancel the active
parking assistance.
R You can also engage transmission position
h prematurely. The vehicle redirects and
does not drive as far into the parking space.
If you change direction too early, parking
assistance is canceled and Active Parking
Assist is stopped. It is then not possible to
achieve a sensible parking position from the
current position.
Exiting a parking space In order that Active Parking Assist can assist
you when exiting the parking space, the follow-
ing conditions must be fulfilled:
R the border of the parking space must be
high enough at the front and the rear, a
curb, for instance, is not sufficient.
R the border of the parking space must not be
too wide. Your vehicle can be maneuvered
into a position at a maximum of 45° to the
starting position in the parking space.
R a maneuvering distance of at least

3.3 ft
(1.0 m) must be available.
Active Parking Assist can only assist you with
exiting a parking space if you have parked the
vehicle parallel to the direction of travel using
Active Parking Assist.
If PARKTRONIC detects obstacles, Active Park-
ing Assist brakes automatically when exiting
from the parking space. You are responsible
for braking in good time. 162
