Drive on carefully. Have ABS checked imme-
diately at a qualified specialist workshop.
If ABS is malfunctioning, other systems will also
fail, including driving safety systems. Observe
the information relating to the !warning
lamp (
Ypage 196).
ABS regulates brake pressure in such a way that the wheels do not lock when you brake. This
allows you to continue steering the vehicle when
braking.
ABS works from a speed of about 5 mph
(8 km/h), regardless of road-surface conditions. ABS works on slippery surfaces, even when you
only brake gently.
The yellow !warning lamp in the instrument
cluster lights up when the ignition is switched
on. The lamp goes out when the engine starts
running.
Braking
If ABS intervenes when braking, you will feel a
pulsating in the brake pedal.
The pulsating brake pedal can be an indication
of hazardous road conditions and functions as a
reminder to take extra care while driving.
XIf ABS intervenes: continue to depress the
brake pedal with force until the braking sit-
uation is over.
XTo make a full brake application: depress
the brake pedal with full force.
ASR (acceleration skid control)
General notes
Important safety notes
Observe the important safety guidelines for the
driving safety system (Ypage 54).
ASR can neither reduce the risk of an accident
nor suspend the laws of physics if the driver
does not pay attention when pulling away or
accelerating. ASR is only an aid. Always adapt
your driving style to suit the prevailing road and
weather conditions.
If you activate or deactivate the all-wheel drive
in a vehicle with this option, ASR will be deacti- vated for the duration of the activation/deacti-
vation process. Vehicles without steering wheel buttons: if ASR
is malfunctioning, the
:indicator lamp lights
up while the engine is running and the engine
power may be reduced (
Ypage 196).
ASR significantly improves traction, i.e. the
transmission of power from the tires to the road surface, and thus increases the vehicle's driving
stability. If the driving wheels start to spin, ASR
brakes individual drive wheels and limits the
engine torque. ASR thus significantly assists you
when pulling away and accelerating, especially
on wet or slippery roads.
If traction on the road surface is not sufficient,
even ASR will not allow you to pull awa
y without
difficulty. The type of tires and total weight of the
vehicle as well as the gradient of the road also
play a crucial role.
If ASR intervenes, the dwarning lamp in the
instrument cluster flashes.
Activating/deactivating ASR
GWARNING
If deactivated, ASR will not attempt to stabi-
lize the vehicle during pulling away and accel- eration. There is an increased risk of skidding
and of an accident.
Only deactivate ASR in the situations descri-
bed in the following.
!If you deactivate ASR, ESP®will still inter-
vene to stabilize the vehicle. Frequent braking
automatically triggered by ESP
®can damage
the brake system.
For this reason, deactivate ASR only briefly
and when absolutely necessary.
When ESP®is intervening and the dwarning
lamp in the instrument cluster is flashing, leave
Driving safet ysystem s55

ASR on. In this case, only depress the acceler-
ator pedal as far as required when pulling away.
XPress theàbutton.
If ASR is deactivated, the dwarning lamp
in the instrument cluster lights up.
ASR is automatically activated when the engine
is started.
It may be best to deactivate ASR briefly in the
following situations:
Rwhen using snow chains
Rin deep snow
Ron sand or gravel
If you deactivate ASR:
Rengine torque is not limited and the drive
wheels are able to spin. The spinning wheels
will then achieve a cutting effect for better
traction.
Rtraction control remains active through brake
intervention. If a drive wheel attains its tire
traction limit because one side of the road is
slippery, for example, that wheel is braked.
The traction is then increased in this situation.
Ractive brake intervention by ESP®to increase
driving stability remains active. The d
warning lamp in the instrument cluster
flashes when ESP
®is intervening.
BAS (Brake Assist System)
GWARNING
If BAS is malfunctioning, the braking distance
in an emergency braking situation is
increased. There is a risk of an accident.
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 196).
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 196).
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 195).
iOnly use wheels with the recommended tire
sizes. Only then will ESP®function properly.
56Driving safety systems
Safety

remain either on the ground or be fully raised.
Observe the instructions for towing the vehi-
cle with all wheels in full contact with the
ground.
!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
inattentive, the all-wheel drive system can nei-
ther reduce the risk of an accident nor override
the laws of physics. The all-wheel drive system
cannot take road, weather and traffic conditions
into account. The all-wheel drive system is only
an aid. You are responsible for the distance to
the vehicle in front, for vehicle speed and for
braking in good time.
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 251). This is the only way to get the full
benefit from the all-wheel drive system.
For information on "Driving off-road", see
(
Ypage 137).
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 147) 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.

GWARNING
If you tighten the adapter bolts when the vehi-
cle is raised, the jack could tip over. There is a risk of injury.
Make sure that the vehicle is properly pre-
pared for a wheel change. Tighten the adapter
bolts with particular care and attention.
Always observe the instructions and safety
notes on "Changing a wheel" (
Ypage 267).
GWARNING
If you do not tighten the bolts of the adapter to
the specified tightening torque, the adapter
may come loose with the spare wheel. There
is a risk of an accident.
Tighten the bolts of the adapter to the speci-
fied tightening torque. Have the spare wheel
replaced with a complete wheel and an extra- wide tire at a qualified specialist workshop
immediately.
!Vehicles with Super Single tires: if you
install the spare wheel, do not exceed the
maximum speed of 40 mph (60 km/h)and do
not drive further than 65 miles(100 km).

lose a wheel while driving. There is a risk of
accident.
Never oil or grease wheel bolts. In the event of
damage to the threads, contact a qualified
specialist workshop immediately. Have the
damaged wheel bolts or hub threads
replaced/renewed. Do not continue driving.
GWARNING
If you tighten the wheel bolts or wheel nuts
when the vehicle is raised, the jack could tip
over. There is a risk of injury.
Only tighten the wheel bolts or wheel nuts
when the vehicle is on the ground.
Always observe the instructions and safety
notes on "Changing a wheel" (
Ypage 267).
Only use wheel bolts or wheel nuts that have
been designed for the wheel and the vehicle. For safety reasons, we recommend that you only
use wheel bolts or wheel nuts which have been
approved for Sprinter vehicles and the respec-
tive wheel.
!For a steel wheel, only use the short wheel
bolts to mount the steel spare wheel. Using
other wheel bolts to mount the steel spare
wheel could damage the brake system.
!On vehicles equipped with a tire pressure
monitor, electronic components are located

Lowering the vehicle
GWARNING
The wheels could work loose if the wheel nuts and bolts are not tightened to the specified
tightening torque. There is a risk of accident.
Have the tightening torque immediately
checked at a qualified specialist workshop
after a wheel is changed.
!Only use the jack pump lever middle rod and
the rod with the largest diameter as a lug
wrench extension. Only slide the middle rod
as far as it will go onto the lug wrench. The
rods may otherwise bend and be distorted to
such an extent that they can no longer be
used as a pump lever for the jack.
!Vehicles with Super Single tires: if you
install the spare wheel, do not exceed the
maximum speed of 40 mph (60 km/h) and do
not drive further than 65 miles(100 km).
The transmission could otherwise be dam-
aged by the difference in wheel rotation
speeds.

XUsing the pump lever, slowly turn the lowering
screw on the jack through approximately one
revolution and carefully lower the vehicle
(
Ypage 268).
XPut the jack aside.
XPull the rod with the smallest diameter off the
pump lever.
The shortened pump lever serves as a lug
wrench extension.
XStarting with the middle rod, slide the lug
wrench extension as far as it will go onto the
lug wrench.
XUsing the extended lug wrench, tighten the
wheel bolts evenly in a crosswise pattern in
the sequence indicated ( :toB).
Tighten the wheel bolts to the following tight-
ening torques:
RSteel wheel 177 lb-ft(240 Nm )
RAlloy wheel 133 lb-ft(180 Nm )
Tighten the wheel nuts to a tightening torque
of 133 lb-ft (180 Nm).
XPush the piston on the hydraulic jack in again
and close the pressure release screw.
XVehicles with all-wheel drive: turn the jack
spindle clockwise as far as it will go
(
Ypage 268).
XStow the jack and the rest of the vehicle tools
in the vehicle again.
iYou can now install the hub caps on steel
wheels with wheel bolts. The installing proce-
dure depends on whether the hub cap acts as
a trim that covers the whole wheel, or just
covers the center.
XWheel with hub cap: position the opening for
the tire valve in the hub cap over the tire valve.
XPush the edge of the hub cap with both hands
against the wheel until it clicks into place.
Make sure the hub cap retaining catches
engage on the steel wheel.
XWheel with central hub cap: position the
retaining lugs of the central hub cap over the
wheel bolts.
XHit the center of the hub cap to engage it on
the wheel.
XSecure the faulty wheel in the spare wheel
bracket (Ypage 274).
XVehicles with Super Single tires: transport the
defective rear wheel in the load area. The rear wheel is too large for the spare wheel bracket.
XCheck the tire pressure of the newly mounted
wheel and adjust it if necessary.
Observe the recommended tire pressure
(
Ypage 251).
XRetighten the wheel bolts or wheel nuts to the
specified tightening torque after the vehicle
has been driven for 30 miles (50 km).
When using a wheel or spare wheel with a new or newly painted wheel rim, have the wheel bolts or
nuts retightened again after approximately 600
to 3,000 miles (1,000 to 5,000 km). Observe the
specified tightening torque.
