Things to remember when driving
116
Things to remember when driving
Break-in period
Moving parts need breaking-in time to adjust to
each other. Please follow the instructions below
in order to achieve the optimal service life and
economy of operation for your vehicle.
Engine and differential
Always obey all official speed limits.
Up to 1,200 miles/2,000 km
Drive at varying engine and road speeds, but do
not exceed an engine speed of 4500 rpm or a
road speed of 100 mph/160 km/h.
Avoid full-throttle operation and use of the
transmission's kick-down mode.
After driving 1,200 miles/2,000 km
Engine and vehicle speeds can be gradually
increased.
Tires
Due to technical factors associated with their
manufacture, tires do not achieve their full trac-
tion potential until after an initial break-in
period. Therefore, drive cautiously during the
first 200 miles/300 km.
Brake system
Brakes require an initial break-in period of
approx. 300 miles/500 km to achieve optimized
contact and wear patterns between brake pads
and rotors. Drive cautiously during this break-in
period.
Clutch
The function of the clutch reaches its optimal
level only after a distance driven of approx.
300 miles/500 km. During this break-in period,
engage the clutch gently.
Following part replacement
The same break-in procedures should be
observed if any of the components mentioned
above have to be renewed in the course of the
vehicle's operating life.
Saving fuel
The fuel consumption of your vehicle depends
on several factors. You can lower fuel consump-
tion and the environmental impact by taking
certain measures, adjusting your driving style
and having the vehicle serviced regularly.
Remove any unneeded cargo
Additional weight increases fuel consumption.
Remove any mounted parts after you
have finished using them
Remove unneeded additional mirrors, the roof
rack and the rear luggage rack after use.
Mounted parts affect the vehicle's aerodynam-
ics and increase fuel consumption.
Close the windows and glass roof
An open glass roof or window causes higher air
resistance and thus increases fuel consump-
tion.
Check tire inflation pressure regularly
Check the tire inflation pressure at least twice a
month and before embarking on a long journey,
and correct it if necessary.
Low tire inflation pressure causes higher rolling
resistance and thus increases fuel consumption
and tire wear.
Set off immediately
Do not let the engine warm up while the car is
still standing, but set off immediately at moder-
ate engine speed. This is the fastest way for the
cold engine to reach its operating temperature.

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
General information on caring for your BMW
can be found on page213.

Giving and receiving assistance
228 To avoid jerking and the associated
stresses on vehicle components when
towing, always use nylon ropes or nylon straps.
Attach the tow rope to the tow fittings only, as
attaching it to other parts of the vehicle could
result in damage.<
With a tow truck: vehicle without xDrive
Have the BMW transported with a tow truck
with a so-called lift bar or on a flat bed.
Do not tow the vehicle with just the rear axle
raised as this may cause the steering to turn.
With a tow truck: vehicle with xDrive
Do not tow a BMW with xDrive with just
the front or rear axle raised, otherwise the
wheels could lock up and the transfer case
could be damaged.<
Have the BMW transported on a flatbed surface
only.
Tow-starting
Avoid tow-starting the vehicle whenever possi-
ble; instead, jump-start the engine, refer to
page225. Vehicles with a catalytic converter
should only be tow-started when the engine is
cold, vehicles with an automatic transmission
cannot be tow-started at all.1.Switch on hazard warning flashers, comply
with local regulations.
2.Switch on the ignition, refer to page55.
3.Shift into 3rd gear.
4.Have the vehicle tow-started with the clutch
depressed and slowly release the clutch.
After the engine starts, immediately
depress the clutch completely again.
5.Stop at a suitable location, remove the tow
bar or rope and switch off the hazard warn-
ing flashers.
