Making a tire repair
Tire repair consists of the following sections.
Fig. 169 Parts of the
Tire Mobility System Fig
. 170 Connector for
the Tire Mobility System
Assembling Tire Mobility System
- Open the lid 0 of the electric air pump~ fig. 169.
- Pull the plug© and the pressure hose G)with the gauge
out of the housing.
- Screw the pressure hose© of the electric air pump onto
the flange © of the sealant bottle
G).
- Push the sealant bottle with the flange down into the
recess
G) on the lid of the electric air pump.
- Remove the dust cap from the valve of the defective tire.
- Screw the hose @) onto the valve
G) ~ fig. 170.
- Insert the plug©~ fig. 169 into the socket for the ciga-
rette lighter.
Inflating tire
- Move the switch®~ fig. 170 on the electric air pump 31
to position I. After 5 minutes, tire pressure must have
reached at least 1.8 bar.
~
3> The e lectric air pump should never run for longer than 8 minutes.

the required tire pressure of at least 1.8 bar has not been
reached, follow the instructions in the section Re­
inflating tire.
Re-inflating tire
-Remove the hose from the valve and pull the plug out of
the socket.
- Drive the vehicle slowly 10 meters backward or forward.
This helps to distribute the sealant better.
- Remove the empty inflation bottle and screw the hose
G)
=> page 265, fig. 169 from the electric pump directly onto
the valve.
- Insert the plug ©=>
page 265, fig. 169 into the socket for
the cigarette lighter.
- Move the switch
@ => page 265, fig. 170 on the electric
air pump
31 to position I. After 5 minutes, tire pressure
must have reached at least
1 .8 bar.
- Switch the electric air pump off - switch in position
0. If
the required tire pressure of at least 1.8 bar has not been reached, it is not possible to make a repair with the tire
sealant. Seek professional assistance.
Disassembling Tire Mobility System
- Remove the hose from the valve and pull the plug out of
the socket.
- Screw the dust cap onto the valve.
- Place the empty sealant bottle back in the original pack-
aging and cl ip it in place under the floor so that no tire
sealant can run out into t he vehicle. -
Place the electric air pump in the luggage compartment
for the time being.
- Start driving right away so that the sealant is distributed
in the tire.
& WARNING
• Follow the manufacturer's safety instructions on the decal for
the air pump and the sealant bottle.
• If a tire pressure of 1.8 bar cannot be achieved after pumping
for 5 minutes, the tire is too severely damaged. Do not continue to
drive.
• Seek professional assistance if it is not possible to repair the
tire with the tire sealant.
[ i] Tips
• Do not operate the electric air pump for more than 8 minutes
without stopping, otherwise it can overheat. When the air pump has
cooled down, you can continue to use it.
• If sealant has escaped, allow it to dry, then you can peel it off. •

Final check
After driving for a short distance , tire pressure
must be checked
- After driving for about 10 minutes, stop and check the
tire pressure .
- If tir e pressure is still at least 1.3 bar, inflate the tire to
specified pressure (see driveas side B -pillarl, drive to the
next repair shop and have the tire and the sealant bottle
replaced.
~

_____________________________________________ W_ h_ a_t _d_ o_l _ d_o _ n_o_ w_ ? _ __._
- If tire pressure is less than 1.3 bar, the tire is too severely
damaged. Do not continue to drive. Seek professional
assistance.
& WARNING
If tire pressure is less than 1.3 bar after driving for 10 minutes, the
tire is too severely damaged. Do not continue to drive. Seek profes­
sional assistance.
[ i] Tips
After a tire repair, have the sealant bottle replaced at a dealership.
This restores full functionality to the Tire Mobility System. •

& WARNING
• Using force without control to speed the wheel change up can
cause the vehicle to slip off the jack and cause serious personal
injuries.
• Do not loosen the wheel bolts more than one turn before you
raise the vehicle with the jack . - Risk of injury!
[ i] Tips
• Never try and use the hexagonal socket in the handle of the
screwdriver to loosen or tighten the wheel bolts.
• If a wheel bolt sits very tight, you may find it easier to loosen by
carefully pushing down on the end of the wheel bolt wrench with
one foot only . As you do, hold on to the car to keep yourself stable
and take care not to slip. •
Rais ing the vehicle
The vehicle must be lifted with the jack first before the
wheel can be removed.

proper positioning of
lifting jack
-Find the mounting point on the rocker panel which is
closest to the flat tire ~ fig. 174 -arrows-.
- Crank the jack up until it can be positioned under the lift
point on the vehicle.
- Align the jack so the claw~ fig. 175@ grips the
mounting point on the rocker panel and the flexible base
plate @ is flat on the ground.
- Continue to crank the jack until the wheel is lifted just
clear of the ground.
Recesses at the front and rear of the underbody rib mark the proper
mounting locations for the jack=> fig. 174 . There is
only one desig­
nated jack mounting point for each wheel.
Do not apply the jack
anywhere else=>&.
The jack should be positioned approximately 6 in. (15 cm) behind
the front wheel or 10 in. (25 cm) in front of the rear wheel.
An
unstable surface under the jack can cause the vehicle to slip off
the jack. Always provide a firm base for the jack on the ground. If
necessary place a sturdy board or similar support under the jack. On
hard, slippery surfaces (such as tiles) use a rubber mat or similar to
prevent the jack from slipping=> &. .,

wheel if you do not follow safety precautions:
-Mounting the jack under the vehicle at any other place than
indicated above may damage the vehicle or may result in
personal injuries.

vehicle to slip off the jack. Always provide a firm base for the
jack on the ground.
If necessary, use a sturdy board under the
jack.
- On hard, slippery surface (such as tiles) use a rubber mat or
similar to prevent the jack from slipping.
• To help prevent injury to yourself and your passengers: -Do not raise the vehicle until you are sure the jack is securely
engaged.
