Notes on breaking in a new vehicle
To preserve the engine during the Nrst 1000 miles
(1500 km):
= Drive at varying road speeds and engine
speeds.
= No faster than 85 mph (140 km/h).
= Drive the vehicle in drive mode A or  .
= Shis to the next higher gear at the very latest
when the needle reaches the last third before
the red area in the tachometer.
= Do not shis down manually in order to brake.
= Avoid overstraining the vehicle, e.g. driving at
full throttle.
= Increase the engine speed only gradually and
accelerate the vehicle to full speed aser
1000 miles (1500 km).
This also applies when the engine or parts of the drivetrain have been replaced.
150Driving and parking

Please also observe the following breaking-innotes:
= In certain handling and driving safety systems,
the sensors adjust automatically while a cer-
tain distance is being driven aser the vehicle
has been delivered or aser repairs. Full sys-
tem eMectiveness is reached only when this
teaching-in process has concluded.
= Brake pads, brake disks and tires that are
either new or have been replaced achieve opti-
mum braking eMect and grip only aser driving
several hundred kilometers. Compensate the
reduced braking eMect by applying greater
force to the brake pedal.
Notes on driving
&WARNING Risk of accident due to objects
in the driver\bs footwell
Objects in the driver\bs footwell may impede
pedal travel or block a depressed pedal.
This jeopardizes the operating and road safety
of the vehicle.
Stow all objects in the vehicle securely so that they cannot get into the driver\bs
footwell.Always install the Ooor mats securely
and as prescribed in order to ensure that
there is always suPcient room for the
pedals.Do not use loose Ooor mats and do not
place Ooor mats on top of one another.&WARNING Risk of accident due to incor-
rect footwear
Incorrect footwear includes, for example:
= Shoes with platform soles
= Shoes with high heels
= Slippers
There is a risk of an accident.
Always wear suitable footwear so that
you can operate the pedals safely.&WARNING Risk of accident if the vehicle is
switched oM while driving
If you switch oM the vehicle while driving,
safety functions are restricted or no longer
available.
This may aMect the power steering system and
the brake force boosting, for example.
You will need to use considerably more force
to steer and brake, for example.
Do not switch oM the vehicle while driv-
ing.&DANGER Risk of death caused by exhaust
gases
Combustion engines emit poisonous exhaust
gases such as carbon monoxide. Inhaling
these exhaust gases is hazardous to health
and leads to poisoning.
Never leave the engine or, if present, the
auxiliary heating running in an enclosed
space without suPcient ventilation.Driving and parking151

&WARNING Risk of skidding and of an acci-
dent due to shising down on slippery road
surfaces
If you shis down on slippery road surfaces to
increase the engine braking eMect, the drive
wheels may lose traction.
Do not shis down on slippery road surfa-
ces to increase the engine braking
eMect.&DANGER Risk of fatal injury due to poison-
ous exhaust gases
If the tailpipe is blocked or suPcient ventila-
tion is not possible, poisonous exhaust gases
such as carbon monoxide may enter the vehi- cle. This is the case, for example, if the vehicle
gets stuck in the snow.
Keep the tailpipe and the area around
the vehicle free from snow when the
engine or the stationary heater is run-
ning.Open a window on the side of the vehicle
facing away from the wind to ensure an
adequate supply of fresh air.&WARNING Risk of accident and injury due
to being under the inOuence of alcohol
and drugs while driving
Drinking and driving and/or taking drugs and
driving are very dangerous combinations. Even a small amount of alcohol or drugs can aMect
your reOexes, perceptions and judgment.
The possibility of a serious or even fatal acci-
dent are greatly increased when you drink or
take drugs and drive.
Do not drink or take drugs and drive or
allow anyone to drive who has been
drinking or taking drugs.&WARNING Risk of accident due to the
brake system overheating
If you leave your foot on the brake pedal when
driving, the brake system may overheat.
This increases the braking distance and the
brake system can even fail.Never use the brake pedal as a footrest.Do not depress the brake pedal and the
accelerator pedal at the same time while
driving.*NOTE Engine damage due to excessively
high engine speeds
The engine will be damaged if you drive with
the engine in the overrevving range.
Do not drive with the engine in the over- revving range.*NOTE Wearing out the brake linings by
continuously depressing the brake pedalDo not depress the brake pedal continu-
ously whilst driving.To use the braking eMect of the engine,
shis to a lower gear in good time.152Driving and parking

*NOTE Damage to the drivetrain and
engine when pulling awayDo not warm up the engine while the
vehicle is stationary. Pull away immedi-
ately.Avoid high engine speeds and driving at
full throttle until the engine has reached
its operating temperature.*NOTE Damage to the catalytic converter
due to non-combusted fuel
The engine is not running smoothly and is mis-
Nring.
Non-combusted fuel may get into the catalytic
converter.
Only depress the accelerator pedal
slightly.Have the cause rectiNed immediately at
a qualiNed specialist workshop.*NOTE Reduced battery life due to frequent
short-distance trips
The 12 V battery may not be suPciently
charged when the vehicle is used only for
short-distance trips. This reduces the life of
the battery.
Drive longer distances regularly to
charge the battery.*NOTE Damage to the vehicle due to not
observing the maximum permitted head-
room clearance
If the vehicle height is greater than the maxi- mum permitted headroom clearance, the roof
and other parts of the vehicle may be dam-
aged.
Observe the signposted headroom clear- ance.If the vehicle height is greater than the permitted headroom clearance, do not
enter.Observe the changed vehicle height with add-on roof equipment.\bPlease bear in mind that all the speed values
stated in this Operator\bs Manual are approxi-
mate and are subject to a certain tolerance.
Notes on driving with a roof load, trailer or fully laden vehicle
When driving with a loaded roof luggage rack or trailer as well as with a fully laden or fully occu-
pied vehicle, the vehicle\bs driving and steering
characteristics change.
You should therefore bear the following in mind:
= Do not exceed the permissible roof load and
towing capacity. Also observe the information
in the Technical Data.
= Distribute the roof load and the load inside the
vehicle evenly, placing heavy objects at the
bottom. Also comply with the notes on loading the vehicle (  page 109).
= Drive attentively, and avoid abrupt starts, brak-
ing and steering as well as rapid cornering.
Driving and parking153

Advice on driving on salt-strewn roadsThe braking eMect is limited on salt-strewn road
surfaces.
Therefore, observe the following notes:
= Due to salt build-up on the brake disks and
brake pads, the braking distance can increase
considerably or result in one-sided braking.
= Maintain a much greater safety distance to the
vehicle traveling in front.
Remove salt build-up as follows: = Brake occasionally, paying attention to the
traPc conditions
= Carefully depress the brake pedal at the end
of the journey and when starting the next jour- ney
Notes on hydroplaning
Hydroplaning can take place if a certain depth of
water has built up on the road surface.
Observe the following notes during heavy precipi-
tation or in conditions in which hydroplaning may
occur:
= Reduce speed=Avoid tire ruts
= Avoid sudden steering movements
= Brake carefully\bAlso observe the notes on regularly checking
wheels and tires (  page 318).
Notes on driving through water on the road
Water ingress can damage the engine, electrics
and transmission.
Water can also enter the air intake of the engine and cause engine damage.
Observe the following if you have to drive through
water:
= The water, when calm, may reach no higher
than the lower edge of the vehicle body.
= Drive at a walking pace at most; water can
otherwise enter the vehicle interior or engine
compartment.
= Vehicles traveling in front, or oncoming vehi-
cles, can create waves which may exceed themaximum permissible depth of water.
The braking eMect of the brakes is reduced aser
fording. Brake carefully, paying attention to the
traPc conditions until braking power has been
fully restored.
Notes on oM-road driving
&WARNING Risk of accident if you do not
keep to line of fall on inclines
If you drive at an angle or turn on an incline,
the vehicle could slip sideways, tip and roll-
over.
Always drive on inclines in the line of fall
(straight up or down) and do not turn.&WARNING Risk of Nre caused by Oamma-
ble material on hot exhaust system com-
ponents
Flammable material such as leaves, grass or
twigs may ignite if they come into contact with
hot parts of the exhaust system.
When driving on an unpaved road or oM-
road, check the vehicle underside regu-
larly.154Driving and parking

In particular, remove trapped plant parts
or other Oammable material.If there is damage, consult a qualiNed
specialist workshop immediately.
When driving oM-road, sand, mud and water or
water mixed with oil, etc., may get into the brakes. This may lead to a reduction in braking eMect or
even a total brake failure as a result of increased
wear. The braking characteristics will vary
depending on the material that has entered the
system. Clean the brakes aser driving oM-road. If
you then notice reduced braking eMect or hear
scraping noises, have the brake system checked
at a qualiNed specialist workshop. Adapt your driv-
ing style to the changed braking characteristics.
*NOTE Damage caused by driving over
obstacles
The vehicle can be damaged by:
= Driving onto high curbs or unpaved roads.
= Quickly driving over obstacles such as
curbs, speed bumps or potholes.
= Heavy objects hitting the underbody or
chassis components.Do not drive over obstacles that could damage the vehicle.Check the vehicle regularly for damage
during oM-road driving.Adjust the vehicle speed to suit the road
surface conditions.If there is damage, consult a qualiNed
specialist workshop immediately.+ENVIRONMENTAL NOTE Environmental
damage due to non-observance of prohibi- tion signs
Environmental protection has priority. Treat
nature with respect.
Be sure to observe prohibition signs.\bThe vehicle is designed for easily negotiable
and moderate oM-road terrain. When driving
oM-road, make sure there is suPcient ground
clearance.Checklist before driving oM-road
Check the following points before driving oM-road:
= Fuel level
= Engine oil level: Nll engine oil to the maximum
level to ensure full gradeability (  page 285)
= Tire-change tool kit and spare wheel
= Tires and wheels\bFurther information about special all-terrain
tires for retroNtting can be obtained from a
qualiNed specialist workshop.
OM-road driving
Read this section before driving your vehicle oM-
road. Practice by driving over gentler oM-road ter-
rain Nrst.
= Observe the notes on the cross-country ABS
(  page 179).
= Select the ) ( page 160) drive program
before driving oM-road.
= Always keep the engine running and in gear
when driving on downhill gradients and slopes. Observe the notes on driving in mountainous
terrain.
Driving and parking155

=Do not drive on unknown terrain that is not
easily visible and stay on marked paths.
= Always keep the doors and windows closed
while the vehicle is in motion.
= Deactivate Active Distance Assist DISTRONIC
and cruise control.
= Adapt your driving style to the terrain.
= Do not use the HOLD function on steep down-
hill or uphill gradients with slippery or loose
surfaces.
Driving on sand
When driving on sand, also observe the following instructions:
= Select the ) drive program.
= Shis to a lower gear.
= Drive quickly to overcome the rolling resist-
ance; the vehicle may otherwise dig itself in.
= Drive in the tracks of other vehicles if possi-
ble. Make sure that the following prerequisites
are met:
- the tire ruts are not too deep.
- the sand is Nrm enough.-
there is suPcient ground clearance.
Fording
Also observe the following information when ford-
ing:
= Drive no faster than 6 mph (10 km/h).
= The water, when calm, may reach no higher
than the lower edge of the vehicle body.
= Switch oM automatic climate control
(  page 144).
= Ensure that a bow wave does not form as you
drive.
= Do not stop in the water and do not switch oM
the engine. Ensure the ECO start/stop func- tion is switched oM ( page 158).
Driving in mountainous terrain
Also observe the following information when driv-
ing in mountainous terrain:
= Avoid high engine speeds.
= Use the braking power of the engine when
driving downhill.= Shis to a lower gear on uphill gradients and on
long, steep downhill gradients.
= Activate DSR before driving downhill, if neces-
sary (  page 194).
Check-list aser driving oM-road
Driving oM-road places greater demands on your
vehicle than driving on normal roads. Check the entire vehicle for damage and foreign bodies
every time aser driving oM-road. Foreign bodies in
the wheels or drivetrain can lead to imbalances
and therefore vibrations.
= If the ) driving mode is selected: select
another driving mode.
= Deactivate DSR.
= Apply the brakes to dry them aser fording.
= Check that the service brake is working nor-
mally aser a long downhill stretch.
= Clean the following components every time
aser driving oM-road:
- license plate number
- headlamps and tail lamps
- tires, wheels and wheel arches156Driving and parking

-underbody
= Aser driving through sand, mud, water or
gravel, have the following components
checked and cleaned:
- brake disks and brake pads
- tires and wheels
- axle joints
