Overrun cut-off
The gasoline/diesel supply is cut off if
the driver's foot is completely removed
from the accelerator pedal when the en-
gine is overrunning at engine speeds
outside of the idling control range.
General driving tipsWarning
G
Drinking and driving and/or taking drugs
and driving are very dangerous combina-
tions. Even a small amount of alcohol or
drugs can affect your reflexes, percep-
tions and judgment. The possibility of a
serious or even fatal accident is sharply
increased when you drink or take drugs
and drive.
Never drink or take drugs and drive or al-
low anyone to drive after drinking or tak-
ing drugs.
Warning
G
There is no power-steering assistance
when the engine is not running.
You will need to use significantly more
force to steer and could therefore lose
control of the vehicle and cause an acci-
dent.
Never switch off the engine while driving.
!
CAUTION
Do not hold the steering wheel in its
end positions for longer than neces-
sary (e.g. when turning or maneuver-
ing).
The hydraulic pump can be damaged
by the increased temperature of the
hydraulic fluid.

Driving in wet conditions Driving on flooded roads
If you are forced to drive on stretches of
road on which water has collected,
please note that:\4
the water level must not reach above
the lower edge of the front bumper
\4
the maximum speed at which you
may drive is walking speed
TiresThe tires are particularly important for
the operating and road safety of the ve-
hicle. You should therefore check the
pressure, tread and condition of the tires
on a regular basis.
A tire dealer, a qualified specialist work-
shop or any authorized Sprinter Dealer
will be able to provide further informa-
tion regarding the:\4
list of recommended makes of tire
\4
tire load-bearing capacity (LI Load
Index)
\4

dex)
\4

Warning
G
The vehicle may hydroplane despite hav-
ing adequate tire tread depth and being
driven at low speeds, depending on the
depth of water on the road surface.
For this reason, avoid tire ruts and brake
carefully.
!
CAUTION
Note that vehicles in front or oncom-
ing vehicles create waves.
This may mean that the maximum
permitted water depth is exceeded.
These notes must be observed to
avoid the risk of engine damage.

Modifications to the brake system or
wheels are not permissible, nor is the
use of spacer plates or brake dust
shields. Any such modifications will in-
validate the vehicle’s general operating
permit.Treadwear indicators (TWI) are required
by law. These indicators are located in
six places on the tread circumference
and become visible at a tread depth of
approximately 1/16 in (1.6 mm), at
which point the tire is considered worn
and should be replaced.
The Treadwear Indicator appears as a
solid band across the tread.
Warning
G
If you feel a sudden significant vibration
or ride disturbance, or you suspect that
possible damage to your vehicle has oc-
curred, you should turn on the hazard
warning flashers, carefully slow down,
and drive with caution to an area which is
a safe distance from the road.
Inspect the tires and the vehicle undercar-
riage for possible damage. If the vehicle
or tires appear unsafe, have the vehicle
towed to the nearest authorized Sprinter
Dealer or tire dealer for repairs.

Specified tire inflation pressures must
be maintained. This applies particularly
if the tires are subject to extreme oper-
ating conditions (e.g. high speeds, heavy
loads, high ambient temperatures).For detailed information on tires, see
"Tires and wheels" (
\2
page 341).
HydroplaningDepending on the depth of the water lay-
er on the road, hydroplaning may occur,
even at low speeds and with new tires.
Reduce vehicle speed, avoid track
grooves in the road and apply brakes
cautiously in the rain.
Warning
G
Although the applicable federal motor ve-
hicle safety laws consider a tire to be
worn when the Treadwear Indicators
(TWI) become visible at approximately 1/
16 in (1.6 mm), do not allow your tires to
wear down to that level. As tread depth
approaches 1/8 in (3 mm) for summer
tires or 1/6 in (4 mm) for winter tires, the
adhesion properties on a wet road are
sharply reduced.
Depending upon the weather and/or road
surface (conditions), the tire traction var-
ies widely.
Warning
G
Do not drive with a flat tire. A flat tire af-
fects the ability to steer or brake the vehi-
cle. You may lose control of the vehicle.
Continued driving with a flat tire or driving
at high speed with a flat tire will cause ex-
cessive heat buildup and possibly a fire.

Tire tractionTire grip is greatly reduced on a wet,
snow covered or icy road. Speed and
driving style must therefore be adapted
to suit road conditions. The safe speed
on a wet, snow covered or icy road is al-
ways lower than on a dry road.
Below a tread depth of 1/8 in (3 mm),
tire grip begins to decrease rapidly on
wet roads.
Pay particular attention to the condition
of the road whenever the outside tem-
peratures is close to the freezing point.In winter, install M+S radial tires with a
minimum tread depth of approximately
1/6 in (4 mm) on all wheels to ensure
normal balanced handling characteris-
tics. On packed snow, they can reduce
y ou r st opp ing di st ance com pa re d to s um -
mer tires.Stopping distance, however, is still con-
siderably greater than when the road is
not covered with snow or ice. Exercise
appropriate caution.
For information on winter tires, see
"Winter tires" (
\2
page 404).
Warning
G
If ice has formed on the road, tire traction
will be substantially reduced. Under such
weather conditions, drive, steer and
brake with extreme caution.
!
CAUTION
Avoid spinning a drive wheel. This
may cause serious damage to the
drive train which is not covered by
the Sprinter warranty.

Tire speed ratingRegardless of the tire speed rating, local
speed limits should be obeyed. Use pru-
dent driving speeds appropriate to pre-
vailing conditions.The vehicles are factory equipped with "L"
(vehicle models type 2500 only) or "N"-rat-
ed tires, which have a speed rating of
74 mph (120 km / h) or 87 mph (140 km /
h) respectively.
For information on speed ratings or for
additional general information on tire
speed markings on the tire side wall, see
"Tire speed rating" (
\2
page 386).
Alignment and balancePoor suspension alignment may result
in:\4
Fast tire wear
\4
Uneven tire wear, such as feathering
and one-sided wear
\4
Vehicle pulling to the left or right
Tires may also cause the vehicle to pull
to the left or right. Alignment will not
correct this condition. See an authorized
Sprinter Dealer for proper diagnosis.
Warning
G
Even when permitted by law, never oper-
ate a vehicle at speeds greater than the
maximum speed rating of the tires.
Exceeding the maximum speed for which
tires are rated can lead to sudden tire fail-
ure, causing loss of vehicle control and
possibly resulting in an accident and / or
serious injury and possible death, for you
and for others.

Improper alignment will not cause vehi-
cle vibration. Vibration may be the result
of a tire and wheel imbalance. Proper
balancing will reduce vibration and avoid
tire cupping and spotty wear.
Coolant temperatureDuring severe operating conditions and
stop-and-go city traffic, the coolant tem-
perature may rise close to approximate-
ly 250 °F (120 °C).
The engine should not be operated with
the coolant temperature over 250 °F
(120 °C). Doing so may cause serious
engine damage which is not covered by
the Sprinter warranty.
Warning
G
\4Driving when your engine is overheat-
ed can cause some fluids, which may
have leaked into the engine compart-
ment, to catch fire. You could be seri-
ously burned.
\4Steam from an overheated engine can
cause serious burns which can occur
just by opening the hood. Stay away
from the engine if you see or hear
steam coming from it.
Turn off the engine, get out of the vehicle
and do not stand near the vehicle until the
engine has cooled down.
