light BMW 135I COUPE 2008 E82 Workshop Manual

Things to remember when driving
116 The risk of hydroplaning increases with declin-
ing tread depth on the tires, refer also to Mini-
mum tread depth on page206.
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 page82.
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 to ensure
that 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 page61.
Never drive with the clutch held down,
with the transmission in idle 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
For general information about taking care of
your BMW, refer to the Caring for your vehicle
brochure.

Things to remember when driving

Convertible
>Position heavy objects as low and as far for-
ward as possible, ideally directly behind the
respective seat backrests.
>Cover sharp edges and corners.
>For very heavy cargo when the rear seat is
not occupied, secure each safety belt in the
opposite buckle.
Securing cargo
>Secure smaller and lighter items using
retaining straps, a cargo bay net
* or draw
straps
*.
>Heavy-duty cargo straps
* for securing
larger and heavier objects are available at
your BMW center. To attach the cargo
straps, there are two lashing eyes, arrows 1,
on the inside wall of the cargo bay. Depend-
ing on your vehicle's equipment, there may
be two additional lashing eyes, arrows2, on
the cargo bay sidewalls.
Follow the information included with the
cargo straps.
Always position and secure the cargo as
described above, so that it cannot endan-
ger the car's occupants, for example if sudden
braking or swerving is necessary.
Never exceed either the approved gross vehicle weight or either of the approved axle loads, refer
to page233, as excessive loads can pose a
safety hazard, and may also place you in viola-
tion of traffic safety laws.
Heavy or hard objects should not be carried
loose inside the car, since they could be thrown
around, for example as a result of heavy braking,
sudden swerves, etc., and endanger the occu-
pants.<
Coupe: roof-mounted
luggage rack*
A special rack system is available as an option
f o r y o u r B M W . C o m p l y w i t h t h e d i r e c t i o n s g i v e n
in the installation instructions.
Mounting points
Fold open the cover.
Loading roof-mounted luggage rack
Because roof racks raise the vehicle's center of
gravity when loaded, they have a major effect on
vehicle handling and steering response.
You should therefore always remember not to
exceed the approved roof load capacity, the
approved gross vehicle weight or the axle loads
when loading the rack.
You can find the applicable data under Weights
on page233.
The roof load must be distributed uniformly and
should not be too large in area. Heavy items
should always be placed at the bottom. Be sure
that adequate clearance is maintained for rais-
ing the glass roof, and that objects do not
project into the opening path of the luggage
compartment lid.
