2013 VOLKSWAGEN JETTA HYBRID engine overheat

Trailer towing
Important information
For technical reasons, your Jetta Hybrid vehicle is not designed to tow a trailer.
Never install a trailer hitch on your vehicle. Towing a trailer will cause expensive damage to the
vehicle and can cause cooling system failure leading to engine failure ⇒ .
WARNING
Towing a trailer can cause cooling system failure, engine overheating, an accident, and
serious personal injuries.
x Never install a trailer hitch on the vehicle.
x Never tow a trailer with the vehicle.
NOTICE
Towing a trailer will cause expensive damage to your vehicle that will not be covered by any
Volkswagen Limited Warranty.

Please perform these steps only in the order listed.

Removing the vehicle key from the ignition
switches off electrical equipment and
activates the steering column lock.
Opening the doors switches off electrical
equipment and activates the steering
column lock.

WARNING
Never stop the engine before the vehicle has come to a complete stop. You can lose control
of the vehicle, crash, and be seriously injured.
x The airbags and safety belt pretensioners will not work when the ignition is switched off.
x The brake booster does not work when both the combustion engine and electric motor are
switched off. More brake pedal pressure will be needed to stop the vehicle.
x The power steering system does not work when both the combustion engine and electric
motor are switched off, and you will need more force to steer the vehicle.
x When the key is removed from the ignition switch, the steering will lock and you will not
be able to steer the vehicle.
NOTICE
If the vehicle has been driven hard for a long time, the engine could overheat when it is
stopped. To reduce the risk of engine damage, let the engine idle in Neutral for about 2 minutes
before you switch off the ignition.
If the ignition is switched on or the engine is running and the driver door is opened, a chime
sounds. The chime is also a reminder to switch off the engine and turn off the ignition before leaving
and locking the vehicle from the outside.
On vehicles with automatic transmissions, the vehicle key can only be removed from the ignition
when the transmission is in Park (P).
After the engine has been switched off, the radiator fan in the engine compartment may keep
running for several minutes, or may start running after the vehicle has been parked for a while, even if
the ignition is switched off and the vehicle key has been removed. The radiator fan shuts off
automatically when the engine has cooled down enough.
Electronic immobilizer

NOTICE
x Never “ride” the brakes by keeping your foot on the brake pedal when you do not want to
brake. This will make the brakes wear faster.
x Before driving downhill, especially on hills that are long or steep, always reduce speed and
shift into lower gear (manual or automatic transmission). This will let the vehicle use engine
braking and reduce the load on the brakes. Otherwise, the brake system could overheat and
even fail. Only use the brakes when you need them to slow the vehicle down more or to stop.
Warning and indicator lights

NOTICE
x When stopping on hills with the transmission in a drive gear, do not use the accelerator to
help prevent the vehicle from rolling backwards. This can cause the automatic transmission to
overheat and be damaged.
x Never let the vehicle coast or roll down a hill in Neutral (N), especially when the engine is
not running. The transmission will not be lubricated and will be damaged.
Automatic transmission malfunction

x While holding the release button down, move the lever all the way down.
WARNING
Improper use of the parking brake can cause accidents and severe injuries.
x Never use the parking brake to slow down the vehicle when it is moving, except in an
emergency. Braking distance is much longer, since only the rear wheels are braked. Always
use the foot brake.
x Never drive with the parking brake partially engaged. This can cause the brake to overheat
and negatively affect the brake system. It will also cause the rear brake pads to wear
prematurely.
x Never activate the throttle manually from the engine compartment when the engine is
running and the automatic transmission is in gear. The vehicle will start to move even if the
parking brake is engaged.
NOTICE
Even though the transmission is in Park (P), the vehicle may move a couple of inches (a few
centimeters) forwards or backwards if you take your foot off the brake pedal after stopping the
vehicle without first firmly setting the parking brake.
A warning signal sounds if you drive faster than about 4 mph (6 km/h) with the parking brake
engaged.
Parking

Facility for repair. Drive slowly and very carefully, allow for the longer stopping distance, and be ready
to push longer and harder on the brake pedal to slow the vehicle down.
Brake booster
The brake booster works only when either the combustion engine or electric motor is running. It
increases the force on the brakes above and beyond the pressure put on the brake pedal by the
driver.
If the brake booster is not working, or if the vehicle has to be towed, you will have to push the brake
pedal harder to make up for the lack of booster assistance and the resulting longer stopping distance
⇒ .
WARNING
New brake pads do not provide maximum braking performance.
x New brake pads do not have the best stopping power for the first 200 miles (320 km) and
must be “broken in.” You can compensate for the slightly reduced braking force by putting
more pressure on the brake pedal.
x Drive with extra care while the new brake pads are being broken in. This reduces the risk
of collisions and serious personal injuries due to a loss of control over the vehicle.
x Never follow other vehicles too closely or put yourself into other situations that might
require sudden, hard braking, especially when the brake pads have not been broken in.
WARNING
Overheated brakes will reduce the vehicle's stopping power and increase stopping distances
considerably.
x When driving downhill, the brakes have to work especially hard and heat up quickly.
x Before driving downhill, especially on hills that are long or steep, always reduce speed
and shift into lower gear (manual or automatic transmission). This will let the vehicle use
engine braking and reduce the load on the brakes. Otherwise, the brake system could
overheat and possibly fail. Only use the brakes when you need them to slow the vehicle down
more or to stop.
x A damaged front spoiler or a non-standard spoiler can reduce airflow to the brakes and
make them overheat.
WARNING
Wet brakes or brakes coated with ice or road salt react slower and need longer stopping
distances.
x Carefully apply the brakes to test them.
x Always dry brakes and clean off ice and salt coatings with a few cautious brake
applications when visibility, weather, road and traffic conditions permit.
WARNING
Driving when the brake booster is not working increases stopping distances and can cause
accidents and serious personal injuries.
x Never let the vehicle coast when the ignition is switched off.
x If the brake booster is not working (such as when the vehicle is being towed), a lot more
pedal force is needed to slow down and stop.

NOTICE
x Never “ride” the brakes by keeping your foot on the brake pedal when you do not want to
brake. Constant pressure on the brake pedal can make the brakes overheat. Riding the brakes
will substantially reduce braking performance, increase stopping distance, and can cause
complete brake system failure.
x Before driving downhill, especially on hills that are long or steep, always reduce speed and
shift into lower gear (manual or automatic transmission). This will let the vehicle use engine
braking and reduce the load on the brakes. Otherwise, the brake system could overheat and
possibly fail. Only use the brakes when you need them to slow the vehicle down more or to
stop.
When the front brakes are serviced, you should have the rear brake pads inspected at the same
time. The wear of all brake pads should be visually checked regularly. The best way to check for brake
pad wear is to have your authorized Volkswagen dealer or authorized Volkswagen Service Facility
visually inspect the pads through the openings in the wheel rims or from underneath the vehicle. If
necessary, the wheels can be taken off for a more thorough inspection.
Braking assistance systems

Anti-Lock Brake System (ABS)
ABS helps to keep the wheels from locking up and helps to maintain the driver's ability to steer and
control the vehicle. This means the vehicle is less likely to skid, even during hard braking:
x Push the brake pedal down hard and hold it there. Don't take your foot off the pedal or reduce the
force on the pedal!
x Do not “pump” the brake pedal or let up on it!
x Steer the vehicle while pushing down hard on the brake pedal.
x ABS stops working if you release or let up on the brake.
When ABS is doing its job, you will notice a slight vibration through the brake pedal and hear a
noise. ABS cannot shorten the stopping distance under all conditions. The stopping distance may
even be longer, for instance, when driving on gravel or on newly fallen snow covering an icy or
slippery surface.
Brake Assist (BAS)
The Brake Assist System can help to reduce stopping distances. If you press the brake pedal very
quickly, BAS detects an emergency situation. It then very quickly builds up full brake system pressure,
maximizing braking power and reducing the stopping distance. This way, ABS can be activated more
quickly and efficiently.
Do not reduce pressure on the brake pedal! BAS switches off automatically as soon as you release or
let up on the brake.
Anti-Slip Regulation (ASR)
ASR reduces engine power directed to spinning wheels and adjusts power to the road conditions.
Even under poor road conditions, ASR can make it easier to get moving, accelerate, and climb hills.
ESC and ASR can help when driving on loose surfaces (such as gravel) and in deep snow. If you get
stuck in deep snow, you may be able to get going again by “rocking” the vehicle back and forth. ESC
and ASR recognize this special driving situation and automatically increase the speed of the front
wheels. Keep pressing the accelerator and let ESC increase the speed of the front wheels to help you
keep moving or get moving again.
Electronic Differential Lock (EDL and XDL)
EDL is applied during regular straight-line acceleration. EDL gently brakes a drive wheel that has lost
traction (spinning) and redirects the drive force to other drive wheels. In extreme cases, EDL
automatically switches off to keep the brake from overheating. As soon as the brake has cooled down,
EDL automatically switches on again.
XDL is an extension of the Electronic Differential Lock system. XDL does not react to drive wheel
slippage when driving straight ahead. Instead, XDL detects slippage of the inside front wheel during
fast cornering. XDL applies enough brake pressure to this wheel in order to stop the slippage. This
improves traction, which helps the vehicle stay on track.
