Important safety notes G
WARNING
Batteries contain toxic and corrosive substan-
ces. If batteries are swallowed, it can result in
severe health problems. There is a risk of fatal
injury.
Keep batteries out of the reach of children. If
a battery is swallowed, seek medical attention
immediately. H
Environmental note Batteries contain dangerous
substances. It is against the
law to dispose of them with
the household rubbish. They
must be collected separately
and recycled to protect the
environment.
Dispose of batteries in an
environmentally friendly
manner. Take discharged
batteries to a qualified spe-
cialist workshop or a special
collection point for used bat-
teries.
The key batteries contain perchlorate mate-
rial, which may require special handling and
regard for the environment. Check with your
local government’s disposal guidelines. Cali-
fornia residents, see www.dtsc.ca.gov/
HazardousWaste/Perchlorate/
index.cfm.
We recommend that you have batteries
changed at a qualified specialist workshop.
Checking the batteries X
Press the 0036or0037 button for longer
than two seconds.
If battery indicator lamp (Y page 66) lights
up briefly, the batteries in the remote 68

wise, change the batteries immediately.
i If the remote control is checked within the
signal reception range of the vehicle, press-
ing the 0037or0036 button:
R lock or
R unlock the vehicle
Changing batteries You need a CR 2025 2 3 V cell battery, which
can be obtained from any qualified specialist
workshop.

X To switch on: press the0072button
repeatedly until the desired heating level
has been set.
X To switch off: press the0072button
repeatedly until all indicator lamps go out.
If the indicator lamps of the current heating
level in the 0072button flash, the seat heat-
ing has switched off automatically. In this
case, too many electrical consumers are
switched on or the battery charge is not suf-
ficient. The seat heating will automatically
switch back to the current heating level when
enough on-board voltage is available again. Steering wheel

WARNING
You could lose control of your vehicle if you
do the following while driving:
R adjust the driver's seat, head restraint,
steering wheel or mirrors
R fasten the seat belt
There is a risk of an accident.
Adjust the driver's seat, head restraint, steer-
ing wheel and mirror and fasten your seat belt
before starting the engine. G
WARNING
If the steering wheel is unlocked while the
vehicle is in motion, it could change position
unexpectedly. This could cause you to lose
control of the vehicle. There is a risk of an
accident.
Before starting off, make sure the steering
wheel is locked. Never unlock the steering
wheel while the vehicle is in motion. G
WARNING
Children could injure themselves if they
adjust the steering wheel. There is a risk of
injury. When leaving the vehicle, always take the
SmartKey with you and lock the vehicle. Never
leave children unsupervised in the vehicle.
The steering wheel can still be adjusted if the
key has been removed. 0043

Motion detector
G
WARNING
The motion detector sends the invisible infra-
red radiation emitted by LEDs (light emitting
diodes).
These LEDs are classified as class 1M lasers
and can damage the retina if you:
R look directly into the unfiltered laser beam
of the motion detector for an extended
period
R look directly into the laser beam of the
motion detector using optical instruments,
e.g. eyeglasses or a magnifying glass.
There is a risk of injury.
Never look directly into the motion detector.
The cargo compartment lighting is also
switched on by the motion detector in the
cargo compartment of Cargo Vans equipped
with this feature.
If the motion detector detects a movement in
the cargo compartment when the vehicle is
stationary, the cargo compartment lighting
switches on for approximately two minutes.
The cargo compartment lighting can be
switched on by the motion detector within
four seconds if:
R the rear interior light switch (Y page 99) is
set to automatic control.
R the vehicle is stationary, the parking brake
is applied and the brake pedal is not being
depressed
Or
R the selector lever is in position Pon vehi-
cles with automatic transmission and the
brake pedal is not being depressed and
R the vehicle has not been locked from the
outside using the key
The motion detector switches off automati-
cally if no change is detected in the vehicle
for several hours, e.g. if a door is opened, if
the ignition key is turned, etc. This prevents
the battery from becoming discharged. Changing bulbs
Important safety notes
G
DANGER
Xenon bulbs carry a high voltage. You can get
an electric shock if you remove the cover of
the Xenon bulb and touch the electrical con-
tacts. There is a risk of fatal injury.
Never touch the parts or the electrical con-
tacts of the Xenon bulb. Always have work on
the Xenon bulbs carried out at a qualified spe-
cialist workshop. G
WARNING
Bulbs, lamps and connectors can get very hot
when operating. If you change a bulb, you
could burn yourself on these components.
There is a risk of injury.
Allow these components to cool down before
changing a bulb.
! Make sure the bulbs are always securely
installed.
If your vehicle is equipped with Bi-Xenon
bulbs, you can recognize this by the following:
the cone of light from the Xenon bulbs moves
from the top to the bottom and back again
when you start the engine. For this to be
observed, the low-beam headlamps must be
switched on before starting the engine.
The bulbs and lamps are an essential compo-
nent of vehicle safety. You must therefore
make sure that these function correctly at all
times. Have the headlamp setting checked
regularly.
R Always switch off the vehicle's lighting sys-
tem before changing a bulb.
This will prevent a short circuit.
R Do not touch the glass tube of new bulbs
with your bare hands. Always use a clean,
lint-free cloth or only touch the base of the
bulb when installing.
Even minor contamination can burn into
the glass surface and reduce the service life
of the bulbs. 100

Useful information
This Operator's Manual describes all models
as well as standard and optional equipment
of your vehicle that were available at the time
of going to print. Country-specific variations
are possible. Note that your vehicle may not
be equipped with all of the described func-
tions. This also applies to systems and func-
tions relevant to safety.
Read the information on qualified specialist
workshops (Y page 26). Breaking-in notes
The first 1000 miles (1500 km)
New or replaced brake pads and brake disks
only reach their optimum braking effect after
a few hundred miles (a few
hundred kilometers). Until then, compensate
for this by applying greater force to the brake
pedal.
For the service life and economy of your vehi-
cle it is crucial that you break in the engine
with due care.
R Therefore, protect the engine for the first
1000 miles (1500 km) by driving at varying
vehicle and engine speeds.
R Avoid overstraining the vehicle and high
engine speeds during this period, e.g. driv-
ing at full throttle. Do not exceed 00C6of the
maximum speed for each gear.
R Do not change down a gear manually in
order to brake.
R Try to avoid depressing the accelerator
pedal beyond the point of resistance (kick-
down).
R The shift ranges 3,2or 1should only be
engaged when driving slowly, e.g. when
driving in mountainous terrain.
After 1000 miles (1500 km), you can increase
the engine speed gradually and accelerate
the vehicle to full speed. i
You should also observe these notes on
breaking-in if the engine or parts of the
drive train on your vehicle have been
replaced. Driving
Important safety notes
G
WARNING
If you switch off the ignition while driving,
safety-relevant functions are only available
with limitations, or not at all. This could affect,
for example, the power steering and the brake
boosting effect. You will require considerably
more effort to steer and brake. There is a risk
of an accident.
Do not switch off the ignition while driving. G
WARNING
If the parking brake has not been fully
released when driving, the parking brake can:
R overheat and cause a fire
R lose its hold function.
There is a risk of fire and an accident. Release
the parking brake fully before driving off. Battery isolating switch
Important safety notes !
Make sure that the key is in position 0in
the ignition lock and wait at least 20 sec-
onds before disconnecting or connecting
the battery isolating switch. You could oth-
erwise damage electrical system compo-
nents.
You can use the battery isolating switch to
disconnect the power supply to all your vehi-
cle's consumers. This will prevent uncontrol-
led battery discharge caused by off-load cur-
rent consumption.
If your vehicle is equipped with an auxiliary
battery in the engine compartment, you will
need to disconnect both batteries. Only then 136
