2009 BMW 335I XDRIVE CONVERTIBLE engine overheat

Driving
56 place the transmission in neutral or engage
selector lever or transmission position P and
forcefully apply the parking brake to prevent the
car from moving.<
Avoid frequent starting in quick succes-
sion as well as repeated start attempts in
which the engine does not start. Otherwise, the
fuel is not burned or incompletely burned and
there is a danger of overheating and damaging
the catalytic converter.<
Do not wait for the engine to warm up while the
vehicle remains stationary. Start driving right
away, but at moderate engine speeds.
Manual transmission
Remote control in the ignition lock or, with con-
venient access, inside the vehicle, refer to
page34.
1.Depress the brake.
2.Depress the clutch and shift to neutral posi-
tion.
3.Press the start/stop button.
The starter operates automatically for a certain
time, and stops automatically as soon as the
engine has started.
Automatic transmission
Remote control in the ignition lock or, with con-
venient access, inside the vehicle, refer to
page34.
1.Depress the brake.
2.Move the selector lever to position P.
3.Press the start/stop button.
The starter operates automatically for a certain
time, and stops automatically as soon as the
engine has started.
Switching off the engine
Always take the remote control with you
when you leave the vehicle.
When parking, apply the parking brake force-
fully, otherwise the vehicle could begin to roll.<
Manual transmission
1.With the car at a standstill, press the start/
stop button.
2.Shift into first gear or reverse.
3.Forcefully apply the parking brake.
4.Removing the remote control from the igni-
tion lock, refer to page55.
Automatic transmission
1.With the car at a standstill, move the selec-
tor lever to position P.
2.Press the start/stop button.
3.Forcefully apply the parking brake.
4.Removing the remote control from the igni-
tion lock, refer to page55.
Parking brake
The parking brake is primarily intended to pre-
vent the vehicle from rolling while parked; it
brakes the rear wheels.
Indicator lamp
The indicator lamp is lit, and when you
drive off an acoustic signal sounds in
addition. The parking brake is still
applied.
Indicator lamp for Canadian models.
Applying
The lever locks in position automatically.

Things to remember when driving
118 The risk of hydroplaning increases with declin-
ing tread depth on the tires, refer also to Mini-
mum tread depth on page203.
Driving through water
Drive through water on the road only if it is
not deeper than 1 ft/30 cm, and then only
at walking speed at the most. Otherwise, the
vehicle's engine, the electrical systems and the
transmission may be damaged.<
Use the parking brake on inclines
On inclines, do not hold the vehicle for a
lengthy period using the clutch; use the
parking brake instead. Otherwise greater clutch
wear will result.<
For more information about the drive-off assis-
tant, refer to page85.
Braking safely
Your BMW is equipped with ABS as a standard
feature. Applying the brakes fully is the most
effective way of braking in situations in which
this is necessary. Since the vehicle maintains
steering responsiveness, you can still avoid
possible obstacles with a minimum of steering
effort.
Pulsation of the brake pedal, combined with
sounds from the hydraulic circuits, indicate that
ABS is in its active mode.
Driving in wet conditions
When roads are wet or there is heavy rain,
briefly exert gentle pressure on the brake pedal
every few miles. Monitor traffic conditions to
ensure that this maneuver does not endanger
other road users. The heat generated in this
process helps dry the pads and rotors. Full
braking efficiency will then be available when
you need it.
Hills
To prevent overheating and the resulting
reduced efficiency of the brake system,
drive long or steep downhill gradients in the
gear in which the least braking is required. Even
light but consistent brake pressure can lead to high temperatures, brake wear and possibly
even brake failure.<
You can increase the engine's braking effect by
shifting down, all the way to first gear if neces-
sary. This strategy helps you avoid placing
excessive loads on the brake system. Down-
shifting in manual mode of the automatic trans-
mission, refer to page58.
Never drive with the clutch held down,
with the transmission in neutral or with
the engine switched off; otherwise, engine
braking action will not be present or there will be
no power assistance to the brakes or steering.
Never allow floor mats, carpets or any other
objects to protrude into the area around the
pedals, otherwise pedal function could be
impaired.<
Corrosion on brake rotors
When the vehicle is driven only occasionally,
during extended periods when the vehicle is not
used at all, and in operating conditions where
brake applications are less frequent, there is an
increased tendency for corrosion to form on
rotors, while contaminants accumulate on the
brake pads. This occurs because the minimum
pressure which must be exerted by the pads
during brake applications to clean the rotors is
not reached.
Should corrosion form on the brake rotors, the
brakes will tend to respond with a pulsating
effect that even extended application will fail to
cure.
When the vehicle is parked
Condensation forms while the automatic cli-
mate control is in operation, and then exits
under the vehicle. Traces of condensed water
under the vehicle are therefore normal.
Before driving into a car wash

can be found on page213.
