Each time the ignition is turned to ON/RUN or ACC/ON/
RUN, the ESC system will be on, even if it was turned off
previously.
— External Light Failure Indicator Light — If
Equipped
The External Light Failure Indicator will come on when a
failure to one of the following lights is detected:
• Direction Indicators
• Backup Lights
• Parking Lights
• Daytime Running Lights
• License Plate Lights
The failure relating to these lights could be:
• One or more blown bulbs
• A blown protection fuse
• A break in the electrical connection
— Tire Pressure Monitoring System (TPMS)
Warning Light
The warning light switches on and a message is displayed
to indicate that the tire pressure is lower than the recom-
mended value and/or that slow pressure loss is occurring.
In these cases, optimal tire duration and fuel consumption
may not be guaranteed.
Should one or more tires be in the condition mentioned
above, the display will show the indications corresponding
to each tire.
CAUTION!
Do not continue driving with one or more flat tires as
handling may be compromised. Stop the vehicle,
avoiding sharp braking and steering. If a tire puncture
occurs, repair immediately using the dedicated tire
repair kit and contact an authorized dealer as soon as
possible.
Each tire, including the spare (if provided), should be
checked monthly when cold and inflated to the inflation
pressure recommended by the vehicle manufacturer on the
vehicle placard or tire inflation pressure label. (If your
vehicle has tires of a different size than the size indicated
96 GETTING TO KNOW YOUR INSTRUMENT PANEL
Page 99 of 300
on the vehicle placard or tire inflation pressure label, you
should determine the proper tire inflation pressure for
those tires.)
As an added safety feature, your vehicle has been
equipped with a Tire Pressure Monitoring System (TPMS)
that illuminates a low tire pressure telltale when one or
more of your tires is significantly under-inflated. Accord-
ingly, when the low tire pressure telltale illuminates, you
should stop and check your tires as soon as possible, and
inflate them to the proper pressure. Driving on a signifi-
cantly under-inflated tire causes the tire to overheat and
can lead to tire failure. Under-inflation also reduces fuel
efficiency and tire tread life, and may affect the vehicle’s
handling and stopping ability.
Please note that the TPMS is not a substitute for proper tire
maintenance, and it is the driver ’s responsibility to main-
tain correct tire pressure, even if under-inflation has not
reached the level to trigger illumination of the TPMS low
tire pressure telltale.
Your vehicle has also been equipped with a TPMS malfunc-
tion indicator to indicate when the system is not operating
properly. The TPMS malfunction indicator is combined
with the low tire pressure telltale. When the system detects
a malfunction, the telltale will flash for approximately oneminute and then remain continuously illuminated. This
sequence will continue upon subsequent vehicle start-ups
as long as the malfunction exists. When the malfunction
indicator is illuminated, the system may not be able to
detect or signal low tire pressure as intended. TPMS
malfunctions may occur for a variety of reasons, including
the installation of replacement or alternate tires or wheels
on the vehicle that prevent the TPMS from functioning
properly. Always check the TPMS malfunction telltale after
replacing one or more tires or wheels on your vehicle to
ensure that the replacement or alternate tires and wheels
allow the TPMS to continue to function properly.
CAUTION!
The TPMS has been optimized for the original equip-
ment tires and wheels. TPMS pressures and warning
have been established for the tire size equipped on
your vehicle. Undesirable system operation or sensor
damage may result when using replacement equip-
ment that is not of the same size, type, and/or style.
Aftermarket wheels can cause sensor damage. Using
aftermarket tire sealants may cause the Tire Pressure

SAFETY FEATURES
Four-Wheel Anti-Lock Brake System (ABS)
The Four-Wheel ABS is designed to aid the driver in
maintaining vehicle control under adverse braking condi-
tions. The system operates with a separate computer to
modulate hydraulic pressure, to prevent wheel lock-up
and to help avoid skidding on slippery surfaces.
The system’s pump motor runs during an ABS stop to
provide regulated hydraulic pressure. The pump motor
makes a low humming noise during operation, which is
normal.
The ABS includes an amber ABS Warning Light. When the
light is illuminated, the ABS is not functioning. The system
reverts to standard non-anti-lock brakes. Turning the igni-
tion OFF and ON again may reset the ABS if the fault
detected was only momentary.
WARNING!
•The ABS contains sophisticated electronic equip-
ment that may be susceptible to interference caused
(Continued)
WARNING! (Continued)
by improperly installed or high output radio trans-
mitting equipment. This interference can cause pos-
sible loss of anti-lock braking capability. Installation
of such equipment should be performed by qualified
professionals.
• Pumping of the Anti-Lock Brakes will diminish their
effectiveness and may lead to a collision. Pumping
makes the stopping distance longer. Just press firmly
on your brake pedal when you need to slow down or
stop.
• The ABS cannot prevent the natural laws of physics
from acting on the vehicle, nor can it increase brak-
ing or steering efficiency beyond that afforded by the
condition of the vehicle brakes and tires or the
traction afforded.
• The ABS cannot prevent collisions, including those
resulting from excessive speed in turns, following
another vehicle too closely, or hydroplaning.
• The capabilities of an ABS equipped vehicle must
never be exploited in a reckless or dangerous manner
that could jeopardize the user ’s safety or the safety of
others.

WARNING!(Continued)
the performance of the ESC system. Changes to the
steering system, suspension, braking system, tire
type and size or wheel size may adversely affect ESC
performance. Improperly inflated and unevenly
worn tires may also degrade ESC performance. Any
vehicle modification or poor vehicle maintenance
that reduces the effectiveness of the ESC system can
increase the risk of loss of vehicle control, vehicle
rollover, personal injury and death.
ESC Operating Modes
The ESC system has two available operating modes.
Full On
This is the normal operating mode for ESC. Whenever the
vehicle is started, the ESC system will be in On mode. This
mode should be used for most driving situations. ESC
should only be turned to Partial Off for specific reasons as
noted below.
Partial Off
This mode is entered by momentarily pushing the ESC Off
switch. This mode is intended to be used if the vehicle is in deep snow, sand or gravel conditions and more wheel spin
than ESC would normally allow is required to gain trac-
tion.
To turn ESC on again, momentarily pushing the switch
again. This will restore the normal ESC On mode of
operation.
NOTE:
To improve the vehicle’s traction when driving
with snow chains, or starting off in deep snow, sand or
gravel, it may be desirable to switch to the Partial Off mode
by pushing the switch. Once the situation requiring ESC to
be switched to the Partial Off mode is overcome, turn ESC
back on by momentarily pushing the switch. This may be
done while the vehicle is in motion.
WARNING!
When in “Partial Off” mode, the TCS functionality of
ESC, (except for the limited slip feature described in
the TCS section), has been disabled and the “ESC Off
Indicator Light” will be illuminated. When in “Partial
Off” mode, the motor power reduction feature of TCS
is disabled, and the enhanced vehicle stability offered
by the ESC system is reduced.

ESC Activation/Malfunction Indicator Light And
ESC OFF Indicator Light
The ESC Activation/Malfunction Indicator Light
in the instrument cluster will come on when the
ignition switch is turned to the MAR (ACC/ON/
RUN) position for four seconds. If the ESC
Activation/Malfunction Indicator Light comes on continu-
ously with the vehicle operating running, a malfunction
has been detected in the ESC system. If this light remains
on after several ignition cycles, and the vehicle has been
driven several miles (kilometers) at speeds greater than
30 mph (48 km/h), see your authorized dealer as soon as
possible to have the problem diagnosed and corrected.
The ESC Activation/Malfunction Indicator Light (located
in the instrument cluster) starts to flash as soon as the tires
lose traction and the ESC system becomes active. The ESC
Activation/Malfunction Indicator Light also flashes when
TCS is active. If the ESC Activation/Malfunction Indicator
Light begins to flash during acceleration, ease up on the
accelerator and apply as little throttle as possible. Be sure to
adapt your speed and driving to the prevailing road
conditions. NOTE:
•
The ESC Activation/Malfunction Indicator Light and
the ESC OFF Indicator Light come on momentarily each
time the ignition switch is turned ON.
• Each time the ignition is turned ON, the ESC system will
be ON even if it was turned off previously.
The ESC OFF Indicator Light indicates the Elec-
tronic Stability Control (ESC) is partially off.
Regenerative Braking System (RBS)
Your 500e has a Regenerative Braking System
(RBS). The RBS reduces the high voltage battery
consumption of the vehicle, particularly in stop-
and-go city traffic. The electric motors which
propel the vehicle forward can operate as generators when
braking. The RBS recharges the high voltage battery under
certain braking conditions by recapturing energy that
would otherwise be lost while braking. The electric power
that is generated goes back into the high voltage battery for
later use, for example when acceleration is desired.
106 SAFETY
Page 109 of 300
The RBS uses conventional hydraulic friction brakes, re-
generative braking, or a combination to slow the vehicle. If
the system detects slippery conditions while braking,
ONLY friction is used to slow the vehicle. The RBS can
result in extended life of the hydraulic service brakes;
however, all inspection, scheduled maintenance, and ser-
vice intervals for the vehicle service brakes must be fol-
lowed.
AUXILIARY DRIVING SYSTEMS
Tire Pressure Monitor System
The Tire Pressure Monitor System (TPMS) will warn the
driver of a low tire pressure based on the vehicle recom-
mended cold placard pressure.
The tire pressure will vary with temperature by about 1psi
(7 kPa) for every 12°F (6.5°C). This means that when the
outside temperature decreases, the tire pressure will de-
crease. Tire pressure should always be set based on cold
inflation tire pressure. This is defined as the tire pressure
after the vehicle has not been driven for at least three
hours, or driven less than 1 mile (1.6 km) after a three hour
period. The cold tire inflation pressure must not exceed the
maximum inflation pressure molded into the tire sidewall.
Refer to “Tires – General Information” in “Servicing AndMaintenance” for information on how to properly inflate
the vehicle’s tires. The tire pressure will also increase as the
vehicle is driven. This is normal and there should be no
adjustment for this increased pressure.
The TPMS will warn the driver of a low tire pressure if the
tire pressure falls below the low-pressure warning limit for
any reason, including low temperature effects and natural
pressure loss through the tire.
The TPMS will continue to warn the driver of low tire
pressure as long as the condition exists, and will not turn
off until the tire pressure is at or above the recommended
cold placard pressure. Once the low tire pressure warning
(Tire Pressure Monitoring System Warning Light) illumi-
nates, you must increase the tire pressure to the recom-
mended cold placard pressure in order for the Tire Pressure
Monitoring System Warning Light to turn off. The system
will automatically update and the Tire Pressure Monitoring
System Warning Light will turn off once the system re-
ceives the updated tire pressures. The vehicle may need to
be driven for up to 20 minutes above 15 mph (24 km/h) in
order for the TPMS to receive this information.
For example, your vehicle may have a recommended cold
(parked for more than three hours) placard pressure of 33
psi (227 kPa). If the ambient temperature is 68°F (20°C) and
5
SAFETY 107
Page 110 of 300
the measured tire pressure is 28 psi (193 kPa), a tempera-
ture drop to 20°F (-7°C) will decrease the tire pressure to
approximately 24 psi (165 kPa). This tire pressure is low
enough to turn ON the “Tire Pressure Monitoring System
Warning Light.” Driving the vehicle may cause the tire
pressure to rise to approximately 28 psi (193 kPa), but the
Tire Pressure Monitoring System Warning Light will still be
on. In this situation, the Tire Pressure Monitoring System
Warning Light will turn off only after the tires are inflated
to the vehicle’s recommended cold placard pressure value.
CAUTION!
•The TPMS has been optimized for the original
equipment tires and wheels. TPMS pressures and
warnings have been established for the tire size
equipped on your vehicle. Undesirable system op-
eration or sensor damage may result when using
replacement equipment that is not of the same size,
type, and/or style. The TPM sensor is not designed
for use on aftermarket wheels and may contribute to
a poor overall system performance or sensor damage.
Customers are encouraged to use OEM wheels to
assure proper TPM feature operation.
(Continued)
CAUTION! (Continued)
•Using aftermarket tire sealants may cause the Tire
Pressure Monitoring System (TPMS) sensor to be-
come inoperable. After using an aftermarket tire
sealant it is recommended that you take your vehicle
to an authorized dealership to have your sensor
function checked.
• After inspecting or adjusting the tire pressure, al-
ways reinstall the valve stem cap. This will prevent
moisture and dirt from entering the valve stem,
which could damage the Tire Pressure Monitoring
Sensor.
NOTE:
• The TPMS is not intended to replace normal tire care and
maintenance, or to provide warning of a tire failure or
condition.
• The TPMS should not be used as a tire pressure gauge
while adjusting your tire pressure.
• Driving on a significantly under-inflated tire causes the
tire to overheat and can lead to tire failure.
108 SAFETY
Page 111 of 300
•Under-inflation also reduces the high voltage battery
range and tire tread life, and may affect the vehicle’s
handling and stopping ability.
• It is particularly important for you to check the tire
pressure in all of the tires on your vehicle monthly and
to maintain the proper pressure.
• The TPMS is not a substitute for proper tire mainte-
nance, and it is the driver ’s responsibility to maintain
correct tire pressure using an accurate tire pressure
gauge, even if under-inflation has not reached the level
to trigger illumination of the Tire Pressure Monitoring
System Warning Light.
• Seasonal temperature changes will affect tire pressure,
and the TPMS will monitor the actual tire pressure in the
tire.TPM System
The Tire Pressure Monitor System (TPMS) uses wireless
technology with wheel rim mounted electronic sensors to
monitor tire pressure levels. Sensors, mounted to each
wheel as part of the valve stem, transmit tire pressure
readings to the receiver module.
The TPMS consists of the following components:
• Receiver module
• Four Tire Pressure Monitoring Sensors
• Various Tire Pressure Monitoring System messages,
which display in the instrument cluster
• Tire Pressure Monitoring System Warning Light

Tire Pressure Monitoring Low Pressure Warnings
The Tire Pressure Monitoring System Warning Light
will illuminate in the instrument cluster and a
chime will sound when tire pressure is low in one or more
of the four active road tires. In addition, the instrument
cluster will display a low pressure graphic showing the
low tire pressure tire highlighted in a different color. Should this occur, you should stop as soon as possible and
inflate the tires with low pressure to the vehicle’s recom-
mended cold placard pressure value. Once the system
receives the updated tire pressures, the system will auto-
matically update and the Tire Pressure Monitoring System
Warning Light will turn off. The vehicle may need to be
driven for up to 20 minutes above 15 mph (24 km/h) in
order for the TPMS to receive this information.
TPMS Warning
When a system fault is detected, the Tire Pressure Moni-
toring System Warning Light will flash on and off for 75
seconds and then remain on solid. The system fault will
sound a chime and also display a “Service Tire Pressure
Monitoring System” message in the instrument cluster for
approximately five seconds.
Low Tire Indicator
110 SAFETY
Page 113 of 300
If the ignition switch is cycled, this sequence will repeat,
providing the system fault still exists. If the system fault no
longer exists, the Tire Pressure Monitoring System Warning
Light will no longer flash, and the “Service TPM System”
message will no longer display.
A system fault can occur due to any of the following:
1. Signal interference due to electronic devices or drivingnext to facilities emitting the same radio frequencies as
the TPM sensors.
2. Installing aftermarket window tinting that contains ma- terials that may block radio wave signals. 3. Accumulation of snow or ice around the wheels or
wheel housings.
4. Using tire chains on the vehicle.
5. Using wheels/tires not equipped with TPM sensors.
NOTE:
• The TPMS will not monitor the pressure in a replace-
ment tire installed without a tire pressure sensor.
• If you install a replacement tire in place of a road tire
that has a pressure below the low-pressure warning
limit, upon the next ignition switch cycle, the Tire
Pressure Monitoring System Warning Light will remain
on and a chime will sound. In addition, the highlighted
graphic in the instrument cluster will still display a low
pressure text message and a pressure value in a different
color.
• After driving the vehicle for up to 20 minutes above
15 mph (24 km/h), the Tire Pressure Monitoring System
Warning Light will flash on and off for 75 seconds and
then remain on solid. In addition, the instrument cluster
will display a “Service Tire Pressure Monitoring System”
message.
