Flat tirePreparing the vehicle
Park the vehicle as far as possible from
moving traffic on a hard surface.
Turn on the hazard warning flashers.
Engage the steering wheel lock in the
straight ahead position and set the
parking brake.
Move the selector lever toP (manual
transmission to 1st or reverse gear).
Have any passenger exit the vehicle at
a safe distance from the roadway.
Mounting the spare wheel Preparing the vehicle
Prepare the vehicle as described under
“Preparing the vehicle” on this page.
Take the spare wheel out of the trunk
(page 271).
Lifting the vehicle
Prevent the vehicle from rolling away
by blocking wheels with wheel chocks
(not included) or other sizable objects.
When changing wheel on a level surface:
Place one chock in front of and one be-
hind the wheel that is diagonally oppo-
site to the wheel being changed.
Warning!
G
The dimensions of the spare wheel are dif-
ferent from those of the road wheels. As a
result, the vehicle handling characteristics
change when driving with a spare wheel
mounted. Adapt your driving style accord-
ingly.
The spare wheel is for temporary use only.
When driving with spare wheel mounted, en-
sure proper tire pressure and do not exceed
vehicle speed of 50 mph (80 km/h).
Drive to the nearest Mercedes-Benz Center
as soon as possible to have the spare wheel
replaced with a regular road wheel.
Never operate the vehicle with more than
one spare wheel mounted.

When changing wheel on a hill:
Place chocks on the downhill side
blocking both wheels of the other axle.
Take the two-piece wheel wrench and
the jack out of the vehicle tool kit
(page 272). Assemble wheel wrench.
On whee l to b e change d, loos en b ut do
not yet remove the wheel bolts (ap-
proximately one full turn with wrench).
The jack take-up brackets are located di-
rectly behind the front wheel housings and
in front of the rear wheel housings. 1
Jack
2 Crank
3 Take-up bracket
Place jack on firm ground.
Position jack 1 under the take-up
bracket 3 so that it is always vertical
(plumb-line) as seen from the side,
even if the vehicle is parked on an in-
cline.
Jack up the vehicle until the wheel is a
maximum of 1.2 in (3 cm) from the
ground. Never start engine while vehi-
cle is raised.
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 that the jack
arm is fully seated in the jack take-up brack-
et. Always lower the vehicle onto sufficient
capacity jackstands before working under
the vehicle.

296 Practical hintsBattery
Batteries contain materials that can harm
the environment if disposed of improperly.
Large 12-volt storage batteries contain
lead. Recycling of batteries is the preferred
method of disposal. Many states require
sellers of batteries to accept old batteries
for recycling.
iThe following procedures must be car-
ried out following any interruption of
battery power (e.g. due to reconnec-
tion):
Set the clock (
page 116) (vehi-
cles with COMAND*: see COMAND
operator’s manual).
Resynchronize the ESP
(page 260).
Resynchronize side windows
(page 184).
Resynchronize panorama slid-
ing/pop-up roof (
page 188).
