3Starting position
When you switch on the ignition, all lamps in
the instrument cluster come on. The low-
beam headlamp indicator lamp, high-beam
headlamp indicator lamp, and turn signal
indicator lamps will only come on if activated.
If a lamp in the instrument cluster fails to
come on when the ignition is switched on,
have it checked and replaced if necessary. If
a lamp in the instrument cluster remains on
after starting the engine or comes on while
driving, refer to “Lamps in instrument cluster”
(Y page 219).
If the SmartKey is left in starter switch
position 0 for an extended period of time, it
can no longer be turned in the starter switch.
In this case, the steering is locked. To unlock,
remove SmartKey from the starter switch and
reinsert.
The steering is locked when the SmartKey is
removed from the starter switch.
XAlways remove the SmartKey from the
starter switch when the engine is not in
operation.
This will help to prevent accelerated vehicle
battery discharge or a completely
discharged vehicle battery.
If the SmartKey cannot be turned in the
starter switch, the vehicle battery may not be
sufficiently charged.
XCheck the vehicle battery and charge it if
necessary (Y page 244).

Safety notes
GWarning!
In order to avoid possible loss of vehicle
control the following must be done before the
vehicle is put into motion:
Rseat adjustment
Rhead restraint adjustment
Rsteering wheel adjustment
Rrear view mirror adjustment
Rfastening of seat belts
GWarning!
Do not adjust the driver’s seat while driving.
Adjusting the seat while driving could cause
the driver to lose control of the vehicle.
Never ride in a moving vehicle with the seat
backrest in an excessively reclined position as
this can be dangerous. You could slide under
the seat belt in a collision. If you slide under
it, the seat belt would apply force at the
abdomen or neck. That could cause serious
or fatal injuries. The seat backrest and seat
belts provide the best restraint when the
wearer is in a position that is as upright as
possible and seat belts are properly
positioned on the body.
