component of the engine management system.

248 ‡(120 †).
Additionally, a display
message may appear in

tone may sound. The coolant level is too low. The coolant is too hot and the engine
is no longer being cooled sufficiently.

Automatic transmission
Important safety notes
G
WARNING
It is dangerous to shift the automatic
transmission out of parking position
P or
neutral position N if the engine speed is
higher than idle speed. If your foot is not firmly
on the brake pedal, the vehicle could
accelerate quickly forward or in reverse. You
could lose control of the vehicle and hit
someone or something. Only shift into gear
when the engine is idling normally and when
your right foot is firmly on the brake pedal.
G
WARNING
On slippery road surfaces, never downshift in
order to obtain braking action. This could
result in drive wheel slip and reduced vehicle
control. Your vehicle's ABS will not prevent
this type of loss of control.
G WARNING
Keep in mind that turning off the engine alone
only will shift the automatic transmission into
neutral position
N automatically.
Always shift the automatic transmission into
park position
P before turning off the engine.
Otherwise the vehicle could roll away which
could result in an accident and/or serious
personal injury.
i Bear in mind that the power transmission
between the engine and the transmission
is interrupted when the engine is switched
off. Therefore, to prevent the vehicle from
rolling away, shift the automatic
transmission to position
P and apply the
parking brake when the engine is switched
off and the vehicle is stationary.
