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
is the electrical system fully disconnected
from the power supply.
i Only switch the vehicle to de-energized
using the battery main switch if:
R the vehicle is stationary for a lengthy
period
R it is absolutely necessary
After the power supply has been activated,
you will need to reset the side windows
(Y page 79).
Switching off the power supply !
When you clamp the connector under the
accelerator pedal, make sure that the con- nector does not become damaged or dirty.
It may otherwise not be possible to restore
the electrical connection when the parts
are reassembled. Battery isolating switch in the driver's footwell, on
the right-hand side next to the accelerator pedal

Important safety notes
G
WARNING
Flammable material such as leaves, grass or
twigs may ignite if they come into contact with hot parts of the exhaust system or exhaust
gas flow. There is a risk of fire.
Park the vehicle so that no flammable mate-
rials come into contact with parts of the vehi- cle which are hot. Take particular care not to
park on dry grassland or harvested grain
fields. 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 you leave children unsupervised in the vehi- cle, they could set it in motion by, for example:
R release the parking brake.
R shift the automatic transmission out of the
parking position P.
R start the engine.
In addition, they may operate vehicle equip-
ment and become trapped. There is a risk of
an accident and injury.
When leaving the vehicle, always take the
SmartKey with you and lock the vehicle. Never
leave children unsupervised in the vehicle.
! A moving vehicle can lead to damage to
the vehicle or damage to the drive train.
! When the vehicle is parked, always
remove the key to prevent the battery from becoming discharged. On vehicles with a battery isolating switch,
switch off the power supply if the vehicle isto be out of use for a longer period of time.
Always park your vehicle safely and according
to legal requirements and secure it against
rolling away.
To ensure that the vehicle is properly secured against rolling away unintentionally:
R the parking brake must be firmly applied
R the selector lever must be in position Pand
the key must be removed from the ignition lock
R on steep uphill or downhill gradients, the
front wheels must be turned towards the
curb
R the rear axle must be secured, e.g. with a
wheel chock, on steep uphill or downhill
gradients
Use the wheel chock (Y page 151) to do so.
If you leave the vehicle parked for more than
three weeks:
R connect the batteries to a trickle charger or
R disconnect the vehicle's starter battery or
R switch off the electrical system using the
battery main switch (Y page 137) and
R disconnect the vehicle's auxiliary battery
Otherwise, you need to check the battery's
condition of charge every three weeks, since standby power consumption can drain the
battery. If the battery voltage is lower than
12.2 V, the battery must be charged. Other-
wise, the battery may be damaged by exhaus-
tive discharging.
Be sure to observe the notes on disconnect-
ing and charging the batteries under "Bat-
tery“ (Y page 258). You can obtain informa-
tion about trickle chargers from a qualified
specialist workshop. Parking

the locking springs. Parking the vehicle for a long period
If you park your vehicle for longer than
three weeks: R connect the batteries to a trickle charger or
R disconnect the vehicle's starter battery or
R switch off the electrical system using the
battery main switch (Y page 137) and
R disconnect the vehicle's auxiliary battery

driver's footwell
R additional battery in the engine compart-
ment
R auxiliary battery under the driver's seat
Have the auxiliary battery removed at a quali-
fied specialist workshop. Installing/removing the floor cover-
ing (starter battery) G
WARNING
Objects in the driver's footwell can restrict the pedal travel or obstruct a depressed pedal.
The operating and road safety of the vehicle is
jeopardized. There is a risk of an accident.
Make sure that all objects in the vehicle are
stowed correctly, and that they cannot enter
the driver's footwell. Install the floormats
securely and as specified in order to ensure
sufficient clearance for the pedals. Do not use loose floormats and do not place floormats on
top of one another. X

X To remove: remove screws 0087and take off
trim 0044. X
Remove floor covering 0043.
X To install: place floor covering 0043in the
driver's footwell.
X Slide floor covering 0043underneath the car-
rier of the accelerator pedal and align it at
the base of the driver's seat and at the door sill.
Make sure that the floor covering does notobstruct the accelerator pedal.

back in. Disconnecting/connecting the
starter battery
Important safety notes G
WARNING
During the charging process, a battery produ- ces hydrogen gas. If a short circuit occurs or
sparks are created, the hydrogen gas can
ignite. There is a risk of an explosion.
R Make sure that the positive terminal of a
connected battery does not come into con-
tact with vehicle parts.
R Never place metal objects or tools on a bat-
tery.
R It is important that you observe the descri-
bed order of the battery terminals when
connecting and disconnecting a battery.
R When jump-starting, make sure that the
battery poles with identical polarity are
connected.
R It is particularly important to observe the
described order when connecting and dis-
connecting the jumper cables.
R Never connect or disconnect the battery
terminals while the engine is running.
