MaintenanceThe battery is completely maintenance-
free. That means that the original elec-
trolyte will normally last for the service
life of the battery under moderate
climatic conditions.SymbolsYou will find the following symbols on
your vehicle battery. To avoid injury,
please comply with the corresponding
precautions whenever you work with or
near the battery.
Please read the following infor-
mation before working with the
battery.
Wear eye protection. Do not
allow particles containing
battery acid or lead to come into
contact with your eyes, your skin, or
your clothing.
Battery acid is extremely corro-
sive. Wear eye protection and
protective gloves. Do not tip the
battery. Battery acid can leak from the
ventilation openings.
Ensure that children keep well
away from batteries and battery
acid.
Do not allow sparks or open
flame near the battery. Do not
smoke near the battery. Avoid
sparks from electrical cables or elec-
trical equipment. Turn the key to posi-
tion 0 in the ignition lock when the
battery is disconnected or connected.
Do not short circuit the battery termi-
nals. This creates a risk of personal
injury from high-voltage sparks.
A highly-explosive gas is gener-
ated when the battery is charged.
If acid is accidentally splashed
into your eyes, rinse them thor-
oughly for 15 minutes with clear
water. Following that, consult a physi-
cian immediately. If acid splashes onto
your skin or clothing, rinse immediately
with ample clean water. If acid is acci-
dentally swallowed, consult a physi-
cian immediately.
In order to protect the battery
case from ultraviolet radiation,
do not place it in direct sunlight.
A discharged battery can freeze. Store
the battery in areas where temperature
remains above freezing.

Towing the vehicle
The towed vehicle should always
be the lighter of the two vehicles.
If this is not the case, it will not be
possible to control vehicle handling.<
Tow-startingFor instructions on jump-starting, refer
to page 144.
Never attempt to use your vehicle to
push another vehicle, since damage to
the energy-absorbing bumpers could
result.
Towing a vehicle 1 Put the manual-shift gear lever in
neutral.
2 Towing speed:
45 mph (70 km/h) maximum.
3 Towing distance:
95 miles (150 km) maximum.
4 Leave the ignition key at position 1 to
ensure that brake lamps, turn signal
indicators, horn and windshield
wipers remain operative, and to
prevent the steering lock from
engaging.
5 Switch on the hazard warning
flashers (observe applicable legal
regulations).
Find some means of identifying the
vehicle in tow, for instance, place a sign
or warning triangle in the rear window.
Make sure that the ignition key
remains in position 1 even when
the electrical system has failed to
prevent the steering lock from
engaging.
The steering and brakes are without
power assist when the engine is off.
This means that increased effort is
required for steering and braking.<
Towing with a commercial tow
truck>Do not tow with sling-type equip-
ment.
>Use a wheel-lift or flat bed equip-
ment.
>Please comply with applicable towing
laws.
Never allow passengers to ride in
a towed vehicle for any reason.< 367us124

Interior rearview mirror with automatic dimming featureThe interior rearview mirror with auto-
matic dimming feature reduces blinding
from following traffic by adapting the
intensity of the reflected images to
correspond to levels of light registered
by the unit's sensors. The mirror reverts
to its undimmed setting as soon as the
light source disappears.
One light sensor is mounted on the
front of the mirror housing. This sensor
is directed forward. It measures light
intensity in the area ahead of the
vehicle. A second light sensor is
located on the lower edge of the mirror.
The electronic control system
compares the light intensity from front
and rear. The difference provides the
basic parameter used to modulate an
electrical current and induce chemical 367de398
changes in a semisolid layer incorpo-
rated in the lens.
The semisolid reacts chemically to this
electrical current, thus providing infi-
nitely variable dimming of the mirror
(electrochromic technology).
As a result, it is no longer necessary to
dim the inside rearview mirror manually,
and the driver can concentrate
completely on traffic conditions.
