TIRE PRES. MONITOR
CURRENTLY
UNAVAILABLE
The tire inflation pressure monitor* is un-
able to monitor the tire inflation pressure
due to:

the presence of several when sensors in
the vehicle


excessive wheel sensor temperatures


a nearby radio interference source


unrecognized wheel sensors installed

Remove any extra wheel sensors from the ve-
hicle.
As soon as the causes of the malfunction have
been removed, the tire inflation pressure moni-
tor automatically becomes active again.

Spare wheel S 430, S 500 and S 600
(except Sport Package*)
The spare wheel rim is mounted with a full
sized tire of the same type as on the vehi-
cle, and it is fully functional.However, that spare wheel rim is weight
optimized and has a limited service life of
12 000 miles (20 000 km) use before a
standard wheel rim must replace it.
In case of flat tire, you may temporarily use
the spare wheel.
Do not operate vehicle with more than one
spare wheel mounted.
For more information, see “Rims and tires”
(
page 422).
Warning!
G
The jack is designed exclusively for jacking
up the vehicle at the jack take-up brackets
built into both sides of the vehicle. To help
avoid personal injury, use the jack only to lift
the vehicle during a wheel change. Never
get beneath the vehicle while it is supported
by the jack. Keep hands and feet away from
the area under the lifted vehicle. Always
firmly set parking brake and block wheels
before raising vehicle with jack.
Do not disengage parking brake while the
vehicle is raised. Be certain that the jack is
always vertical (plumb line) when in use, es-
pecially on hills. Always try to use the jack
on level surface. Make sure the jack arm is
fully seated in the jack take-up bracket. Al-
ways lower the vehicle onto sufficient ca-
pacity jackstands before working under the
vehicle.
Warning!
G
Never operate the vehicle with more than
one spare wheel mounted.
The spare wheel rim is for temporary use
only. Use for over a total of 12 000 miles
(20 000 km) (aggregate of all uses) may
cause wheel rim failure leading to an acci-
dent and possible injuries.
The spare wheel should only be used tempo-
rarily and replaced with a regular road wheel
as quickly as possible.

change when driving with a mounted spare
wheel. Adapt your driving style accordingly.

one spare wheel mounted.
The spare wheel is for temporary use only.
When driving with spare wheel mounted, en-
sure proper tire inflation pressure and do
not exceed vehicle speed of 50 mph
