Procedure:
1. Park the vehicle on a firm, level, non-slippery surface.
2. Switch on the hazard warning flasher switch, apply the parking brake, and place the transmission
selector in "P".
3. Everyone must leave the vehicle before you jack it up.
4. Everyone must leave the danger zone, before jacking the vehicle. 5. The vehicle must be safeguarded in accordance
with legal regulations (such as using a warning
triangle).
6. Prevent vehicle from rolling away by blocking wheels with wheel chocks (not supplied with
vehicle) or sizable wood block or stone.
On a level road, place one chock in front of and one
behind the wheel that is diagonally opposite to the
wheel being changed.
When changing a wheel on mild uphill or downhill
grades, place chocks on the downhill side blocking
both wheels of the other axle.
Do not jack the vehicle up more than 1.2 in (30
mm) between the tire and the surface. Otherwise,
the vehicle may tip over and may cause serious
injury or death to you or others.
Precautions when changing a wheel:
For the torque, refer to
"Installing a wheel ";
Do not damage, grease or oil wheel bolts or their
threads.
WARNING!
Do not change wheels on either steep uphill or
downhill grades. The vehicle may begin to move
and fall from the jack which could cause personal
injury and property damage.

JACK Using the Jack
The jack is located together with the vehicle tool kit
under the hatch in the front passenger footwell, refer to
"Vehicle Tool Kit".
1. Loosen the wheel bolts before raising the vehicle.
2. Close the release valve on the jack.
3. Assemble the pump leve r provided and insert it
into the socket on the jack.
4. Secure the lever by turning it clockwise in the socket.
Position the jack under the appropriate jack point and
raise the vehicle by pumping the lever.
WARNING!
To avoid the risk of serious or fatal injuries or vehicle
damage, please bear the fo llowing points in mind:
The jack is intended only for raising the vehicle briefly, for instance, when changing a wheel. If it is
not designed to enable work to be carried out
underneath the vehicle.
Do not crawl under the jacked-up vehicle. For work
under the vehicle, stands must be used.
The jack must be placed on a firm, flat surface only.
Do not change wheels on uphill or downhill gradients under any circumstances.
Make sure that no persons are present in the vehicle when jacking up the vehicle.
Do not start the engine while the vehicle is raised.
Make sure that the distance between the underside of the tires and the ground does not exceed 1.2 in (30
mm). Otherwise the vehicle may tip over.

210 WHAT TO DO IN EMERGENCIES A dead battery can freeze at a temperature of 14
°F
(–10
°C). Never try to start the engine if the battery
is frozen. Thaw the battery out first.
Only use a battery of the same rated voltage and of approximately the same capacity for jump-starting.
The two vehicles must not touch.
Switch off all electrical accessories.
Run the vehicle with the booster battery at idle.
Connect the jumper cables in the sequence given in the illustration. 1. First connect the positive terminals of the two
batteries (see illustration, Items 1 + 2). Start with the
booster battery.
2. Then connect the negative terminal of the vehicle with the booster battery to a vehicle ground point
of the vehicle with the discharged battery, such as
to the engine block (see illustration, Items 3 + 4).
Start with the booster battery.
3. Start the engine in the customary manner.
4. Allow the engine to run for a short time.
5. Before disconnecting the jumper cables from the vehicle with the booster battery, switch on an
electrical consumer (e.g. the blower, but not the
lamps).
6. Disconnect the jumper cables in the reverse order to that in which they were connected.
7. Disconnect the jumper cable from negative terminal and vehicle ground point first (see
illustration, items 3 + 4), then from positive
terminals of the batteries (see illustration 1 + 2).
NOTE: Never try to start the engine with the aid of a
battery quick-charge unit.

TOWING THE VEHICLE
*Vehicle Type 2500 only
WARNING!
Do not tow the vehicle if the key cannot be turned
in the ignition lock.
If the key cannot be turned, the ignition lock re-
mains locked and the vehicle cannot be steered.
With the engine not running there is no power
assistance for the braking and steering systems.
In this case, it is important to keep in mind that a
considerably higher degree of effort is necessary
to brake and steer the vehicle.
The vehicle must not be towed with the front axle
raised and the key in position 2 in the ignition
lock as the drive wheels could then lock due to the
acceleration skid control (ASR) or the optional
Electronic Stability Program (ESP)
*.

Open the hood.
At first, only turn the radiator cap to the first detent to release the pressure from the cooling system.
Only then should the radiator cap be removed
completely.
To add coolant: If the engine is cold:
Add coolant until the coolant level reaches the base
area which is visible through the filler opening (area
moistened).
WARNING!
In order to avoid any possibly serious burns:
If you see flames or smoke coming from the engine compartment, or if the coolant
temperature gauge indicates that the engine is
overheated, do not open the hood. Move away
from the vehicle and do not open the hood until
the engine has cooled. If necessary, call the fire
department.
Do not remove pressure cap on coolant reservoir if engine temperature is above 194 °F (+90 ×C).
A l l o w e n g i n e t o c o o l do w n b e f o r e r e m o v i ng c a p .
The coolant reservoir contains hot fluid and is
under pressure.
Using a rag, slowly open cap approximately 1/2 turn to relieve excess pressure. If opened
immediately, scalding hot fluid and steam will
be blown out under pressure.
WARNING!
Do not spill antifreeze on hot engine parts. Anti-freeze contains ethylene glycol which may burn
if it comes into contact with hot engine parts.
Check coolant level only with the engine switched off and the key in position 0 in the
ignition lock.

BATTERIESThe standard battery is located in the engine
compartment. The auxiliary battery is lo
cated underneath the front
passenger seat (optional equipment).
The battery will not achieve its maximum service life
unless it is kept adequately charged at all times. If the
vehicle is used primarily for short distances, or left
parked for lengthy periods, have the battery charge
checked more frequently.
Disconnecting the Battery
WARNING!
Failure to follow these instructions can result in
severe personal injuries and death.
Never lean over batteries while connecting, you
might get injured, if the battery explodes.
Battery fluid contains sulfuric acid. Do not allow
this fluid to come in contact with eyes, skin or
clothing. In case it does, immediately flush
affected area with water and seek medical help if
necessary.
A battery will also produce hydrogen gas, which
is flammable and explosive. Keep flames or
sparks away from battery, avoid improper
connection of jumper cables, smoking etc.
Use only impact-resistant batteries with a central
gas release cover to prevent corrosion damage and
to prevent occupants from caustic burns in the
event of an accident.
CAUTION!
Do not loosen or remove the battery terminal
clamps while the engine is running or the key is in
the ignition lock as this could damage electrical or
electronic equipment beyond repair. All electrical
consumers must be switched off.
Do not place any metal objects on the battery.
Doing so may cause a short-circuit.
Loosen and remove the negative terminal clamp
first, then the positive terminal.
Afterwards disconnect vent tube from the fitting.

236 MAINTAINING YOUR VEHICLEWiper BladeClean the wiper blade rubber with a clean cloth and
detergent solution.
Light Alloy WheelsA wheel care product should be used for regular
cleaning of the light alloy wheels.
If possible, clean wheels once a week, using a soft
bristle brush and a strong spray of water.
Follow instructions on container.
NOTE: Use only acid-free cleaning materials. The acid
could lead to corrosion.Instrument ClusterUse a gentle dishwashing detergent or mild detergent
for delicate fabrics as a washing solution. Wipe with a
cloth moistened in lukewarm solution. Do not use
scouring agents.Steering Wheel and Gear Selector LeverWipe with a damp cloth and dry thoroughly or clean
with a leather care product.
WARNING!
For safety reasons, remove key from ignition lock
before cleaning the windshield, otherwise the
wiper motor can suddenly turn on and cause in-
jury.
Dirty or iced-up steps create a risk of slipping or
falling. Do not use the step in the front bumper
when it is icy or dirty.
WARNING!
For safety reasons, remove key from ignition lock
before cleaning the wiper blade, otherwise the
wiper motor can suddenly turn on and cause se-
vere personal injuries and death.
