248Vehicle care
If w flashes for 60-90 seconds and
then illuminates continuously, there is a fault in the system. Consult a
workshop.
After inflating, driving may be
required to update the tyre pressure
values in the DIC. During this time w
may illuminate.
If w illuminates at lower temperatures
and extinguishes after some driving,
this could be an indicator for
approaching a low tyre pressure
condition. Check tyre pressure.
Vehicle messages 3 124.
If the tyre pressure must be reduced
or increased, switch off ignition.
Only mount wheels with pressure
sensors, otherwise the tyre pressure
will not be displayed and w
illuminates continuously.
A temporary spare wheel is not
equipped with pressure sensors. The
tyre pressure monitoring system is
not operational for these wheels.
Control indicator w illuminates. For
the further three wheels the system
remains operational.The use of commercially available
liquid tyre repair kits can impair the
function of the system. Factory-
approved repair kits can be used.
External high-power radio equipment
could disrupt the tyre pressure
monitoring system.
Each time the tyres are replaced, tyre pressure monitoring system sensors
must be dismounted and serviced.
For the screwed sensor, replace
valve core and sealing ring. For
clipped sensor, replace complete
valve stem.
Vehicle loading status Adjust tyre pressure to load condition according to the tyre information label
or tyre pressure chart 3 286, and
select the relevant setting in the menu Tyre Load in the DIC, Vehicle
Information Menu 3 118.
Select:
■ Light for comfort pressure up to
3 people.
■ Eco for Eco pressure up to
3 people.
■ Max for full loading.
TPMS Sensor Matching
Process
Each TPMS sensor has a unique
identification code. The identification
code must be matched to a new tyre/ wheel position after rotating the tyres
or exchanging the complete wheel set
and if one or more TPMS sensors
were replaced. The TPMS sensor
Vehicle care249
matching process should also be
performed after replacing a spare tyre with a road tyre containing the TPMS
sensor.
The malfunction light w and the
warning message or code should go
off at the next ignition cycle. The
sensors are matched to the tyre/
wheel positions, using a TPMS
relearn tool, in the following order: left
side front tyre, right side front tyre,
right side rear tyre and left side rear
tyre. The turn signal light at the
current active position is illuminated
until sensor is matched.
Consult your workshop for service or
to purchase a relearn tool. There are
2 minutes to match the first tyre/wheel position, and 5 minutes overall to
match all four tyre/wheel positions. If
it takes longer, the matching process
stops and must be restarted.The TPMS sensor matching process is:
1. Apply the parking brake; on vehicles with automatic
transmission set the selector lever
to P.
2. Turn the ignition on.
3. Press MENU on the turn signal
lever to select the Vehicle
Information Menu in the Driver
Information Centre (DIC).
4. Turn the adjuster wheel to scroll to
the tyre pressure menu.
5. Press the SET/CLR button to
begin the sensor matching
process. A message requesting
acceptance of the process should
display.
6. Press the SET/CLR button again
to confirm the selection. The horn sounds twice to signal the
receiver is in relearn mode.
7. Start with the left side front tyre.
8. Place the relearn tool against the tyre sidewall, near the valve stem.Then press the button to activate
the TPMS sensor. A horn chirpconfirms that the sensor
identification code has been
matched to this tyre and wheel
position.
9. Proceed to the right side front tyre,
and repeat the procedure in Step 8.
10. Proceed to the right side rear tyre,
and repeat the procedure in
Step 8.
11. Proceed to the left side rear tyre, and repeat the procedure in
Step 8. The horn sounds twice to
indicate the sensor identification
code has been matched to the left side rear tyre, and the TPMS
sensor matching process is no
longer active.
12. Turn off the ignition.
13. Set all four tyres to the recommended air pressure level
as indicated on the tyre pressure
label.
14. Ensure the tyre loading status is set according selected pressure
3 118.
Vehicle care253
9. Connect the compressor plug tothe power outlet or cigarette
lighter socket.
To avoid discharging the battery,
we recommend running the
engine.
10. Set the rocker switch on the compressor to I. The tyre is filled
with sealant.
11. The compressor pressure gauge briefly indicates up to 6 bar whilstthe sealant bottle is emptying
(approx. 30 seconds). Then the
pressure starts to drop.
12. All of the sealant is pumped into the tyre. Then the tyre is inflated.
13. The prescribed tyre pressure should be obtained within
10 minutes. Tyre pressure
3 286 . When the correct pressure
is obtained, switch off the
compressor.
If the prescribed tyre pressure is
not obtained within 10 minutes,
remove the tyre repair kit. Move
the vehicle one tyre rotation.
Reattach the tyre repair kit and
continue the filling procedure for
10 minutes. If the prescribed tyre
pressure is still not obtained, the
tyre is too badly damaged. Seek
the assistance of a workshop.
Drain excess tyre pressure with
the button over the pressure indicator.
Do not run the compressor longer
than 10 minutes.
14. Detach the tyre repair kit. Push catch on bracket to remove
sealant bottle from bracket. Screw the tyre inflation hose to the freeconnection of the sealant bottle.
This prevents sealant from
escaping. Stow tyre repair kit in
load compartment.
15. Remove any excess sealant using a cloth.
16. Take the label indicating maximum permitted speed from
the sealant bottle and affix in the
driver's field of view.
17. Continue driving immediately so that sealant is evenly distributedin the tyre. After driving approx.
10 km (but no more than
10 minutes), stop and check tyre
pressure. Screw compressor air
hose directly onto tyre valve and
compressor when doing this.
262Vehicle care
4. Switch on electrical consumers(e.g. headlights, heated rear
window) of the vehicle receiving
the jump start.
5. Reverse above sequence exactly when removing leads.Towing
Towing the vehicle
Insert a screwdriver in the slot at the
short edge of the cap. Release the
cap by carefully moving the
screwdriver sidewards. To prevent
damage it is recommended to place a cloth between the screwdriver and
the frame.
The towing eye is stowed with the vehicle tools 3 245.
Screw in the towing eye as far as it will
go until it stops in a horizontal
position.
Attach a tow rope – or better still a tow
rod – to the towing eye.
The towing eye must only be used for towing and not for recovering the
vehicle.
Switch on ignition to release steering wheel lock and to permit operation of
brake lights, horn and windscreen
wiper.
Transmission in neutral.
Vehicle care265
Thoroughly rinse and leather-off the
vehicle. Rinse leather frequently. Use
separate leathers for painted and
glass surfaces: remnants of wax on
the windows will impair vision.
Do not use hard objects to remove
spots of tar. Use tar removal spray on
painted surfaces.
Exterior lights Headlight and other light covers are
made of plastic. Do not use any
abrasive or caustic agents, do not use
an ice scraper, and do not clean them dry.
Polishing and waxing
Wax the vehicle regularly (at the
latest when water no longer beads).
Otherwise, the paintwork will dry out.
Polishing is necessary only if the paint
has become dull or if solid deposits
have become attached to it.
Paintwork polish with silicone forms a
protective film, making waxing
unnecessary.
Plastic body parts must not be treated with wax or polishing agents.Windows and windscreen wiper
blades
Use a soft lint-free cloth or chamois leather together with window cleaner
and insect remover.
When cleaning the rear window from
inside, always wipe in parallel to the
heating element to prevent damage.
For mechanical removal of ice, use a
sharp-edged ice scraper. Press the
scraper firmly against the glass so
that no dirt can get under it and
scratch the glass.
Remove dirt residues from smearing wiper blades by using a soft cloth and window cleaner. Also make sure to
remove any residues such as wax,
insect residues and similar from the
window.
Ice residues, pollution and continuous wiping on dry windows will damage or
even destroy the wiper blades.Glass panel
Never clean with solvents or abrasive
agents, fuels, aggressive media
(e.g. paint cleaner, acetone-
containing solutions etc.), acidic or
highly alkaline media or abrasive
pads.
Wheels and tyres
Do not use high-pressure jet
cleaners.
Clean rims with a pH-neutral wheel
cleaner.
Rims are painted and can be treated
with the same agents as the body.
Paintwork damageRectify minor paintwork damage with
a touch-up pen before rust forms. Have more extensive damage or rust
areas repaired by a workshop.
Underbody
Some areas of the vehicle underbody
have a PVC undercoating while other critical areas have a durable
protective wax coating.
266Vehicle care
After the underbody is washed, checkthe underbody and have it waxed if
necessary.
Bitumen/rubber materials could
damage the PVC coating. Have
underbody work carried out by a
workshop.
Before and after winter, wash the
underbody and have the protective
wax coating checked.
Liquid gas system9 Danger
Liquid gas is heavier than air and
can collect in sink points.
Take care when performing work
at the underbody in a pit.
For painting work and when using a
drying booth at a temperature above
60 °C, the liquid gas tank must be
removed.
Do not make any modifications to the
liquid gas system.
Towing equipment
Do not clean the coupling ball bar with
a steam-jet or high-pressure jet
cleaner.
Rear carrier system Clean the rear carrier system with a
steam-jet or high-pressure jet cleaner
at least once a year.
Operate the rear carrier system
periodically if not in regular use, in
particular during winter.
Air shutter Clean the shutter system in the front
bumper to maintain correct
functionality.
Interior care Interior and upholsteryOnly clean the vehicle interior,
including the instrument panel fascia
and panelling, with a dry cloth or
interior cleaner.
Clean the leather upholstery with
clear water and a soft cloth. In case of
heavy soiling, use leather care.The instrument cluster and the
displays should only be cleaned using
a soft damp cloth. If necessary use a weak soap solution.
Clean fabric upholstery with a
vacuum cleaner and brush. Remove
stains with an upholstery cleaner.
Clothing fabrics may not be
colourfast. This could cause visible
discolourations, especially on light-
coloured upholstery. Removable
stains and discolourations should be
cleaned as soon as possible.
Clean seat belts with lukewarm water or interior cleaner.Caution
Close Velcro fasteners as open
Velcro fasteners on clothing could damage seat upholstery.
The same applies to clothing with
sharp-edged objects, like zips or
belts or studded jeans.
