BAS (Brake Assist System)
GWARNING
If BA Sis malfunctioning ,th ebraking distanc e
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.

Important safety notes
GDANGER
If the exhaust pipe is blocked or adequate
ventilation is not possible, poisonous gases
such as carbon monoxide (CO) may enter the vehicle. This is the case, for example in
enclosed spaces or if the vehicle gets stuck in
snow. There is a risk of fatal injury.
Switch the auxiliary heating off in enclosed
spaces without extraction systems, e.g. in
garages. If the vehicle is stuck in snow and
you have to leave the auxiliary heating run-
ning, keep the exhaust pipe and the area
around the vehicle free of snow. To ensure anadequate supply of fresh air, open a window
on the side of the vehicle that is not facing into
the wind.

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.

!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.
If you fail to adapt your driving style or if you are

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
Rmove the selector lever from Nto Dor R
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.

Regular wheel and tire checks
GWARNING
Damaged tires can cause tire inflation pres-
sure loss. As a result, you could lose control of
your vehicle. There is a risk of accident.
Check the tires regularly for signs of damage
and replace any damaged tires immediately.
Check the wheels and tires of your vehicle for
damage regularly, i.e. at least every two weeks,
as well as after driving off-road or on rough
roads. Damaged wheels can cause a loss of tire
pressure. Pay particular attention to damage
such as:
Rcuts in the tires
Rpunctures
Rtears in the tires
Rbulges on tires
Rdeformation or severe corrosion on wheels
Regularly check the tire tread depth and the
condition of the tread across the whole width of
the tire (
Ypage 244). If necessary, turn the
front wheels to full lock in order to inspect the
inner side of the tire surface.
All wheels must have a valve cap to protect the valve against dirt and moisture. Do not install
anything onto the valve other than the standard
valve cap or other valve caps approved for your vehicle by dealers listed on the inside of the
front cover. Do not install any other valve caps
or systems, e.g. tire pressure monitor systems.
Regularly check the pressure of all the tires,
particularly prior to long trips. Adjust the tire
pressure if ne
cessary (Ypage 246).
The service life of tires depends on various fac-
tors, including the following:
Rdriving style
Rtire pressure
Rmileage
Tire tread
GWARNING
Insufficient tire tread will reduce tire traction.
The tire is no longer able to dissipate water.
This means that on wet road surfaces, the risk
of hydroplaning increases, in particular where
speed is not adapted to suit the driving con-
ditions. There is a risk of accident.
If the tire pressure is too high or too low, tires may exhibit different levels of wear at differ-
ent locations on the tire tread. Thus, you
should regularly check the tread depth and
the condition of the tread across the entire
width of all tires.
Minimum tire tread depth for:
RSummer tires: âin (3 mm)
RM+S tires: ãin (4 mm)
For safety reasons, replace the tires before
the legally prescribed limit for the minimum
tire tread depth is reached.
Bar marking :for tread wear is integrated into
the tire tread.
Tread wear indicators (TWIs) are required by
law. Six indicators are positioned over the tire
tread. They are visible once the tread depth is
approximately áin (1.6 mm). If this is the case,
the tire is so worn that it must be replaced.
Selecting, mounting and renewing
tires
ROnly mount tires and wheels of the same type
and make.
ROnly mount tires of the correct size onto the
wheels.
RBreak in new tires at moderate speeds for the first 65 miles (100 km).
244Operation
Wheels and tires

Once you have mounted the winter tires:
XCheck the tire pressure (Ypage 246).
XReactivate the tire pressure moni-
tor* (
Ypage 251).
Snow chains
GWARNING
If you drive too fast with snow chains moun-
ted, they may snap. As a result, you could
injure others and damage the vehicle. There is
a risk of an accident.
Observe the maximum permissible speed for
operation with snow chains.
When driving with snow chains installed, do not
exceed the maximum permissible speed of
30 mph (50 km/h). Observe the country-spe-
cific laws and regulations for operation with
snow chains.
!Check the snow chains for damage before
mounting them. Damaged or worn snow
chains may snap and damage the following
components:
Rwheel
Rwheel housing
Rwheel suspension
For this reason, you must use only snow
chains that are free of defects. Observe the
manufacturer's mounting instructions.
!Vehicles with steel wheels: if you mount
snow chains on steel wheels, you may dam-
age the hub caps. Remove the hub caps from
the relevant wheels before mounting the
snow chains.
Snow chains increase traction on roads in wintry
conditions.
For reasons of safety we only recommend using snow chains or traction aids that are approved
for the Sprinter. The snow chains or traction aids
must be of class U or meet the SAE type U
specification. Information on snow chains is
available at any qualified specialist workshop.
When mounting snow chains, please bear the
following points in mind:
RSnow chains cannot be mounted on all
wheel/tire combinations. When mounting the snow chains, note the permissible tire and
snow chain dimensions.
RMount snow chains only in pairs and only to
the rear wheels. On vehicles with twin tires,
mount the snow chains to the outer wheels.
Observe the manufacturer's mounting
instructions.
RVehicles with all-wheel-drive:
snow chains
are not permitted on the front axle. There is
not sufficient space for commercially-availa-
ble snow chains. Information about snow
chains for all-wheel-drive vehicles can be
obtained from an authorized Sprinter Dealer.
ROnly use snow chains when the road is cov-
ered by a layer of snow. Remove the snow
chains as soon as possible when you come to
a road that is not snow-covered.
RThe use of snow chains may be restricted by
local regulations. Observe the appropriate
regulations before mounting snow chains.
RActivate all-wheel drive before driving off with
snow chains (Ypage 145).
RWhen driving with snow chains installed, do
not exceed the maximum permissible speed
of 30 mph (50 km/h).
RCheck the tension of the chains after a dis-
tance of approximately 0.5 miles (1.0 km).
You can deactivate ASR (
Ypage 54) when pull-
ing away with snow chains mounted. This allows
the wheels to spin in a controlled manner, ach-
ieving an increased driving force (cutting
action).
