Use a soft bristle brush or a dry-sham-
poo cleaner in case of excessive dirt.
Seat belts
Use only clear, lukewarm water and
soap.Upholstery
Using aftermarket seat covers or wearing
clothing that have the tendency to give off
coloring (e.g. when wet, etc.) may cause
the upholstery to become permanently dis-
colored. By lining the seats with a proper
intermediate cover, contact-discoloration
will be prevented.
Leather upholstery
Wipe leather upholstery with a damp
cloth and dry thoroughly or clean with
Mercedes-Benz approved Leather
Care.
Exercise particular care when cleaning per-
forated leather as its underside should not
become wet.Wood trims
Dampen cloth using water and use
damp cloth to clean wood trims in your
vehicle.
!The webbing must not be treated with
chemical cleaning agents. Do not dry
the webbing at temperatures above
176°F (80°C) or in direct sunlight.Warning!
G
Do not bleach or dye seat belts as this may
severely weaken them. In a crash they may
not be able to provide adequate protection.
!Do not use solvents like tar remover or
wheel cleaner nor polishes or waxes as
these may be abrasive.

392 Practical hintsWhere will I find...?
In case of a flat tire, you may temporarily
use the spare wheel with collapsible tire
when observing the following restrictions:
Do not exceed a vehicle speed of
50 mph (80 km/h).
Drive to the nearest tire repair facility
to have the flat tire repaired or
replaced as appropriate.
Do not operate vehicle with more than
one spare wheel with collapsible tire
mounted.
For more information, see “Rims and tires”
(
page 439).
Spare wheel bolts
1Wheel bolt for light alloy rims
2Wheel bolt for spare wheel with
collapsible tire (located under plastic
cover on the outside of spare wheel
rim)
Warning!
G
The dimensions of the spare wheel with col-
lapsible tire are different from those of the
road wheels. As a result, the vehicle han-
dling characteristics change when driving
with a spare wheel with collapsible tire
mounted.
The spare wheel with collapsible tire should
only be used temporarily, and should be re-
placed with a regular road wheel as quickly
as possible.

400 Practical hintsReplacing bulbsSafe vehicle operation depends on proper
exterior lighting and signaling. It is there-
fore essential that all bulbs and lamp as-
semblies are in good working order at all
times.
Correct headlamp adjustment is extremely
important. Have headlamps checked and
readjusted at regular intervals and when a
bulb has been replaced. See an authorized
Mercedes-Benz Center for headlamp ad-
justment.
iIf the headlamps are fogged up on the
inside as a result of high humidity,
driving the vehicle a short distance with
the lights on should clear up the
fogging.
iBackup bulbs will be brought into use
when lamps malfunction. Observe the
messages in the multifunction display
(page 382).
