in an emergenc ybraking situation is
increased. There is aris kof an accident.
54Driving safety systems
Safety

In an emergency braking situation, depress
the brake pedal with full force. ABS prevents
the wheels from locking.
Vehicles without steering wheel buttons: if the
BAS driving safety system is malfunctioning,
the : warning lamp lights up while the
engine is running (
Ypage 191).
BAS operates in emergency braking situations.
If you depress the brake quickly, BAS automat-
ically increases the brake pressure, thereby
reducing the stopping distance.
The brakes will function as usual once you
release the brake pedal. BAS is deactivated.
EBD (electronic brake force distribu-
tion)
GWARNING
If EBD is malfunctioning, the rear wheels can
lock, e.g. under full braking. This increases the
risk of skidding and an accident.
You should therefore adapt your driving style
to the different handling characteristics. Have
the brake system checked at a qualified spe-
cialist workshop.
EBD monitors and controls the brake pressure
to the rear wheels. This enables EBD to improve
handling during braking.
Observe the information on warning and indica-
tor lamps (
Ypage 191).
ESP®(Electronic Stability Program)
Important safety notes
GWARNING
If ESP
®is malfunctioning it will not provide
any vehicle stabilization. There is an increased
risk of skidding or of an accident.
Exercise caution when continuing to drive.
Have ESP
®checked at a qualified specialist
workshop.
!Do not run the vehicle on a roller dynamom-
eter (e.g. for performance tests). If you must
operate the vehicle on a roller dynamometer, please consult a qualified specialist workshop
in advance. You could otherwise damage the
drive train or the brake system.
If you activate or deactivate the all-wheel drive
in a vehicle with this option, ESP
®will be deac-
tivated for the duration of the activation/deac-
tivation process.
If ESP
®is malfunctioning, the hindicator
lamp lights up while the engine is running and
the engine power may be reduced
(
Ypage 190).
iOnly use wheels with the recommended tire
sizes. Only then will ESP®function properly.
4ETS (Electronic Traction System)
!A function or performance test should only
be carried out on a two-axle dynamometer.
Before you operate the vehicle on such a
dynamometer, please consult a qualified
workshop. You could otherwise damage the
drive train or the brake system.
4ETS is only active when all-wheel drive is acti-
vated (
Ypage 145).
4ETS ensures permanent drive for all four
wheels, and together with ESP
®it improves the
vehicle's traction.
If a driven wheel spins due to lack of traction:
RWhen pulling away, make use of the traction
control integrated in ESP®. Depress the
accelerator pedal as far as necessary.
RWhile driving, slowly take your foot off the
accelerator pedal.
In wintry driving conditions, always use winter
tires (M+S tires) and if necessary, snow chains
(
Ypage 246). This is the only way to get the full
benefit from the all-wheel drive system.
Crosswind Assist
Crosswind Assist does not work if ESP®is deac-
tivated or disabled because of a malfunction.
Crosswind Assist does not react:
Rin the event of severe jolts and vibrations, e.g.
as a result of uneven surfaces or potholes.
Rif the vehicle loses traction, e.g. on snow or
ice or when hydroplaning.
Rto large and sudden steering movements by
the driver.

Rlicense plates, vehicle lighting, turn signals,
brake lamps and wiper blades for dirt and
damage
Rtires and wheels for firm seating, correct
tire pressure and general condition
Rtrailer tow hitch for play and security
The trailer coupling is one of the most
important vehicle parts with regard to road safety. The separate instructions issued by
the manufacturer pertaining to operation,
care and maintenance should be observed.
Rthat contour markings on attachments and
bodies are in good condition
XRectify any noticeable defects before com-
mencing the journey.
Checks in the vehicle
Emergency equipment and first-aid kit
XCheck the equipment to make sure that it is
accessible, complete and ready for use.
The first aid and breakdown assistance equip-
ment is in the front door stowage compartments
and behind the driver's seat.
Vehicle lighting
XTurn the key to position 2in the ignition lock.
XCheck the lighting system with the aid of a
second person.
XReplace defective bulbs (Ypage 87).
Before driving off
GWARNING
Objects in the driver's footwell may restrict
the clearance around the pedals or block a
depressed pedal. This jeopardizes the oper-
ating and road safety of the vehicle. There is a risk of an accident.
Stow all objects securely in the vehicle so that
they do not get into the driver's footwell.
When using floormats or carpets, make sure
that they are properly secured so that they do
not slip or obstruct the pedals. Do not place
several floormats or carpets on top of one
another.
GWARNING
Unsuitable footwear can hinder correct usage of the pedals, e.g.:
Rshoes with thick soles
Rshoes with high heels
Rslippers
There is a risk of an accident.
Wear suitable footwear to ensure correct
usage of the pedals.
XSecure the load as per the loading guidelines
(Ypage 208).
XStow luggage items securely. Secure the load
as per the loading guidelines (Ypage 208).
XMake sure that the floormats and carpets are
properly secured so that they cannot slip and
obstruct the pedals.
XClose all doors.
Starting the engine
GWARNING
Combustion engines emit poisonous exhaust
gases such as carbon monoxide. Inhaling
these exhaust gases leads to poisoning. There
is a risk of fatal injury. Therefore never leave
the engine running in enclosed spaces with-
out sufficient ventilation.
!Do not depress the accelerator pedal when
starting the engine.
XBefore starting the engine, make sure that:
Rall the doors are closed.
Rall the vehicle occupants are wearing their
seat belts correctly.
Rthe parking brake is applied.
iIf you depress the brake pedal before start-
ing the engine, the pedal travel is short and
pedal resistance is high.
If you depress the brake pedal again after
starting the engine, pedal travel and resist-
ance will be back to normal again.
118Driving
Driving and parking

Rswitch off the electrical system using the bat-
tery main switch (Ypage 116) and
Rdisconnect the vehicle's auxiliary battery
Otherwise, you need to check the battery's con- dition of charge every three weeks, since
standby power consumption can drain the bat-
tery. If the battery voltage is lower than 12.2 V,
the battery must be charged. Otherwise, the
battery may be damaged by exhaustive dis-
charging.
Be sure to observe the notes on disconnecting
and charging the batteries under "Battery"
(
Ypage 223). You can obtain information about
trickle chargers from a qualified specialist work- shop.
If you leave the vehicle parked for longer than
6 weeks, the vehicle may suffer damage as a
result of lack of use. In this event, consult a
qualified specialist workshop.
Driving tips
General notes
Important safety notes
GWARNING
The driver's attention to the road must always be his/her primary focus when driving. For
your safety and the safety of others, we rec-
ommend that you pull over to a safe location
and stop before placing or taking a telephone
call. If you choose to use the telephone while
driving, please use the hands-free device and
only use the telephone when road, weather
and traffic conditions permit.
Some jurisdictions prohibit the driver from
using a mobile phone while driving a vehicle.
Bear in mind that at a speed of just 30 mph
(approximately 50 km/h), your vehicle covers
a distance of 44 feet (approximately 14 m)
ever yse cond.
GWARNING
If you switch off the ignition while driving,
safety-relevant functions are only available
with limitations, or not at all. This could affect, for example, the power steering and the brake
boosting effect. You will require considerably
more effort to steer and brake. There is a risk
of an accident.
Do not switch off the ignition while driving.
!Always observe the ground clearance of the
vehicle and avoid obstacles. On vehicles with a step, ground clearance is further restricted.
Obstacles can damage the vehicle.
If you must drive over obstacles, drive espe-
cially slowly and carefully. If necessary, have
another person direct you.
Drive sensibly – save fuel
In order to save fuel, observe the following tips:
XThe tires should always be inflated to the rec-
ommended tire pressure.
XRemove unnecessary loads.
XRemove roof carriers when they are not nee-
ded.
XWarm up the engine at low engine speeds.
XAvoid frequent acceleration or braking.
XHave all maintenance work carried out as
indicated by the service intervals in the Main-
tenance Booklet or by the service interval dis-
play.
Fuel consumption also increases when driving in cold weather, in stop-start traffic and in moun-
tainous terrain.
Overrun cutoff
If you are in overrun mode and take your foot off
the accelerator pedal, the fuel supply is cut off
when the engine speed is out of the idle speed
control range.
Drinking and driving
GWARNING
Drinking and driving and/or taking drugs and driving are very dangerous combinations.
Even a small amount of alcohol or drugs can
affect your reflexes, perceptions and judg-
ment.
The possibility of a serious or even fatal acci-
dent are greatly increased when you drink or
take drugs and drive.
130Driving tips
Driving and parking

Do not drink or take drugs and drive or allow
anyone to drive who has been drinking or tak-ing drugs.
Emission control
GWARNING
Combustion engines emit poisonous exhaust
gases such as carbon monoxide. Inhaling
these exhaust gases leads to poisoning. There
is a risk of fatal injury. Therefore never leave
the engine running in enclosed spaces with-
out sufficient ventilation.
Certain engine systems are designed to keep
the level of poisonous substances in exhaust
fumes within legal limits.
These systems only work optimally if they are
maintained exactly in accordance with the man-
ufacturer's specifications. Any work on the
engine should therefore be carried out by quali-
fied and authorized technicians at a Sprinter
dealer.
The engine settings must not be changed under any circumstances. In addition, all specific
maintenance work must be carried out at regu-
lar intervals and in accordance with the service
requirements of the dealer listed here on the
inside title page. Details can be found in the
Maintenance Booklet.
Short journey
!
If the vehicle is predominantly used for
short-distance driving or is stationary for long
periods, this could lead to a malfunction in the automatic cleaning function for the diesel par-
ticle filter. This can lead to blockage of the
diesel particle filter. This can also result in fuel
collecting in the engine oil and cause engine
failure.
Therefore, if you mainly drive short distances,
drive on a highway or an inter-urban road for
20 minute severy 300 miles (500 km). This facil-
itates the diesel particle filter's burn-off proc-
ess.
Speed limiter
GWARNING
Exceeding the stated tire load-bearing capa-
city and the approved maximum speed could
lead to tire damage or the tire bursting. There is a risk of accident.
Therefore, only use tire types and sizes
approved for your vehicle model. Observe the
tire load rating and speed rating required for
your vehicle.
As the driver, you must find out about the max-
imum speed of the vehicle permitted for the
tires (tire and tire pressure). In particular, also
observe the tire approval regulations for each
country.
You must not exceed the speed limit for the tires
listed in the tire pressure tables. You can find
information on tire pressures in the "Wheels and
tires" section (
Ypage 246).
You can permanently limit the speed of your
vehicle to 65 mph (105 km/h) or 75 mph
(120 km/h).
We recommend that you have the speed limit
programmed at an authorized Sprinter dealer.
Before overtaking, take into consideration that
the engine speed limiter prevents the speed
increasing beyond the programmed speed limit.
Driving abroad
Service
An extensive network of authorized Sprinter
Dealers is also at your disposal when you are
traveling abroad. Nevertheless, please bear in
mind that service facilities or replacement parts may not always be immediately available. You
can obtain a list of workshops at any authorized
Sprinter Dealer.
Fuel
In some countries, only fuels with a higher sulfur
content are available.
Unsuitable fuel can cause engine damage. Infor-
mation on fuel (
Ypage 273).

longed rolling of the wheels, e.g. when being
towed, will result in transmission damage.
If the vehicle threatens to skid or cannot be
stopped when moving at low speed:
XShift the transmission to neutral position N.
XTry to maintain control of the vehicle using
corrective steering.
Drive particularly carefully on slippery roads.
Avoid sudden acceleration, steering and braking
maneuvers. Do not use cruise control.

Driving off-road
Important safety notes
GWARNING
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.
GWARNING
When driving off-road, your body is subject to
forces from all directions, due to the uneven
surface. You could be thrown from your seat,
for instance. There is a risk of injury.
Always wear a seat belt, even when driving off-
road.
GWARNING
If you drive over obstacles or in ruts, the steer-
ing wheel may jerk out of your grip, causing
injury to your hands.
Always hold the steering wheel firmly with
both hands. When driving over obstacles, you
must expect steering forces to increase
briefly and suddenly.
GWARNING
Flammable material such as leaves, grass or
twigs may ignite if they come into contact with
hot parts of the exhaust system. There is a risk of fire.
When driving off road or on unpaved roads,
check the vehicle's underside regularly. In
particular, remove parts of plants or other
flammable materials which have become
trapped. In the case of damage, contact a
qualified specialist workshop.
!When driving off-road or on unpaved surfa-
ces, check the underside of the vehicle and
the wheels and tires at regular intervals. In
particular, remove any trapped foreign
objects, e.g. stones and branches.
Such foreign objects may:
Rdamage the chassis, the fuel tank or the
brake system
Rcause imbalances and thus vibrations
Rbe flung out when you continue driving
If there is any damage, inform a qualified spe-
cialist workshop.
When driving off-road and on construction sites,
sand, mud and water mixed with oil, for exam-
ple, may get into the brakes. This may lead to a
reduction in braking performance or total brake
failure, also as a result of increased wear. The
braking characteristics will vary depending on
the material that has got into the system. Clean
the brakes after driving off-road. If you then
notice reduced braking performance or hear
scraping noises, have the brake system checked
at a qualified specialist workshop. Adjust your
driving style to the changed braking character-
istics.
Driving off-road or on construction sites increa-
ses the possibility of vehicle damage which may
in turn lead to the failure of certain assemblies
and systems. Adapt your driving style to the off- road driving c
onditions. Drive carefully. Have
any vehicle damage rectified at a qualified spe-
cialist workshop as soon as possible.
When driving on rough terrain, do not shift the
transmission into the neutral position. You could
lose control when attempting to brake the vehi-
cle with the service brake. If your vehicle cannot
manage an uphill slope, drive back down the
slope in reverse gear.
Driving tips135
Driving and parking
Z

When loading your vehicle for driving off-road or
on a construction site, keep the vehicle's centerof gravity as low as possible.
Checklist before driving off-road
XCheck the fuel and DEF levels (Ypage 159)
and top up (Ypage 126).
XEngine: check the oil level (Ypage 216) and
add oil (Ypage 218).
Before driving up or down steep gradients, fill
the oil to the maximum level.
iIf you drive up or down steep gradients, the
4 symbol may appear in the display. The
engine operating safety is not put at risk if you
have filled the engine oil to the maximum level
before the journey.
XVehicle tool kit: check that the jack is work-
ing (Ypage 236).
XMake sure that a lug wrench (Ypage 236),
wooden underlay for the jack, a robust tow
cable and a folding spade are carried in the
vehicle.
XWheels and tires: check the tire tread depth
(Ypage 244) and tire pressure
(Ypage 246).
Rules for driving off-road
!Always bear the vehicle's ground clearance
in mind and avoid obstacles, e.g. deep ruts.
Obstacles may damage the following parts of
the vehicle:
Rthe chassis
Rthe drive train
Rthe fuel and supply tanks
For this reason, you should always drive
slowly when driving off-road. If you have to
drive over obstacles, have the front
passenger direct you.
iWe recommend that you additionally carry a
shovel and a recovery rope with shackle in the
vehicle.
REnsure that loads and items of luggage are
securely stowed or lashed down
(
Ypage 208).
RBefore driving off-road, stop the vehicle and
shift to a low gear.
RIf the surface demands it, temporarily deacti-
vate ASR when pulling away (Ypage 54).
ROnly drive off-road with the engine running
and a gear engaged.
RDrive slowly and smoothly. Walking pace is
necessary in many situations.
RAvoid spinning the drive wheels.
RMake sure that the wheels always remain in
contact with the ground.
RDrive with extreme care over unknown terrain
where you can only see for a short distance.
As a precaution, get out of the vehicle to take
a look at the route to be taken in advance.
RCheck the water depth before fording.
RWatch out for obstacles (e.g. rocks, holes,
tree stumps and ruts).
RAvoid edges where the surface could crumble
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 terrain. 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:
XVehicles with all-wheel drive: deactivate
all-wheel drive (Ypage 145).
XActivate ASR (Ypage 54).
XClean the headlamps and tail lamps and
check them for damage.
XClean the front and rear license plates.
XClean the windshield, windows and exterior
mirrors.
XClean the steps, door sills and grab handles.
This increases safety of footing.
XClean the wheels and tires, wheel arches and
the underbody of the vehicle with a water jet.
This increases road grip, especially on wet
road surfaces.
136Driving tips
Driving and parking

XCheck the wheels and tires and wheel archesfor trapped foreign objects and remove them.
Trapped foreign objects can damage the
wheels and tires or may beflung out from the
veh icle when you continue driving.
XCheck the underbo dyfor trapped branches or
other parts of plants and remove them.
XClean the brake disks, brake padsand axle
jo ints, particular lyafter operation insand,
mud, grit and gravel, water or similarly dirt y
conditions.
XCheck the entire floor assembly, the tires,
wheels, bodywork structure, brakes, steering,
chassis and exhaust system for any damage.
XCheck the service brake for operating safety,
e.g. carry out a brake test.
XIf you notice strong vibrations after driving off-
road, check the wheels and drive train for for-
eign objects again. Remove any foreign
objects which can lead to imbalances and
thus cause vibrations.
Driving systems
Cruise control
General notes
Cruise control maintains the speed of the veh i-
cle for you.
Use cruise control ifroad and traff icconditions
make itappropriate to maintain a steady speed
for a prolonged period. You can set any speed
from 20 mph upwards inincrements of 1 mph.
iIfyou have set km /has the unit for the dig-
ital speedometer (Ypage 167), you can set
any speed from 30 km /hupwards inincre-
ments of 1 km/h.
Cruise control should not beactivated when
driv ing off-road or on construction sites.
Cruise control may not be ableto maintain the
stored speed on uphillordownhill gradients. If
the gradient evens out and the veh icle's speed
does not fall below 20 mph (30 km/h), the
stored speed is resumed.
iThe speed shown in the speedometer may
differ slightly from the speed stored by cruise
control.
Important safety notes
If you fail to adapt your driving style or if you are
inattentive, cruise control can neither reduce
the risk of an accident nor override the laws of
physics. Cruise control cannot take road,
weather and traffic conditions into account.
Cruise control is only an aid. You are responsible
for the distance to the vehicle in front, for vehi-
cle speed, for braking in good time and for stay-
ing in lane.
Do not use cruise control:
Rin traffic conditions that are unsuitable for
driving at a constant speed, e.g. in heavy traf-
fic, on winding roads or off-road.
Ron slippery roads. Braking or accelerating
may cause the drive wheels to lose traction
and the vehicle could then skid.
Rwhen there is poor visibility, e.g. due to fog,
heavy rain or snow.
If there is a change of drivers, make sure that
you inform the new driver about the set cruise
speed.

4ETS ensures permanent drive for all four
wheels, and together with ESP
®it improves the
vehicle's traction.
If a driven wheel spins due to lack of traction:
RWhen pulling away, make use of the traction
control integrated in ESP®. Depress the
accelerator pedal as far as necessary.
RWhile driving, slowly take your foot off the
accelerator pedal
In wintry driving conditions, always use winter
tires (M+S tires) and if necessary, snow chains
(
Ypage 246). This is the only way to get the full
benefit from the all-wheel drive system.

Engaging all-wheel drive
Conditions for engaging/disengaging
All-wheel drive can only be engaged or disen-
gaged if:
Rthe engine is running
Rthe vehicle is stationary
If it is not possible to engage all-wheel-drive:
Rmove the selector lever to position N
Rrelease the brake pedal
Rpress the;button

Engaging/disengaging all-wheel drive
XTo engage/disengage: press the;but-
ton.
The indicator lamp in the ;button flashes.
The h and: indicator lamps light up in
the instrument cluster. ESP
®and ASR are
deactivated for the duration of the engaging/ disengaging process.
If the engaging/disengaging process is suc-
cessful, the hand: indicator lamps in
the instrument cluster go out and ESP
®and
ASR are reactivated.
If the indicator lamp in the ;button is lit,
all-wheel drive is engaged. On vehicles with
steering-wheel buttons, the display then
shows the following message: Four-wheel
drive active.
If the engaging/disengaging process fails, the indicator lamp in the ;button flashes
three times briefly. One of the gear change
conditions was not fulfilled.
As long as the indicator lamp in the ;button
is flashing, you can cancel the engaging/disen-
gaging process by pressing the ;again.
iIf the LOW RANGE transmission ratio
(Ypage 145) is engaged, all-wheel drive can-
not be disengaged.
LOW RANGE transmission ratio
General notes
The LOW RANGE transmission ratio assists you
when driving on difficult terrain. If you engage
LOW RANGE, the engine's performance charac-
teristics and the automatic transmission's shift-
ing characteristics are adjusted accordingly.
The transmission ratio from the engine to the
wheels is around 40% lower than in the on-road position. This increases the drive torque.
