JEEP WRANGLER 2021 Owner handbook (in English)

After 25 miles (40 km), check the lug nut/
bolt torque to be sure that all the lug nuts/
bolts are properly seated against the wheel.
WARNING!
To avoid the risk of forcing the vehicle off
the jack, do not tighten the lug nuts fully
until the vehicle has been lowered. Failure
to follow this warning may result in per-
sonal injury.
FUEL REQUIREMENTS —
GASOLINE ENGINES
This engine is designed to meet all emissions
regulations and provide excellent fuel
economy and performance when using high
quality unleaded gasoline with a minimum
research octane rating (RON) of 91.
Light spark knock at low engine speeds is not
harmful to your engine. However, continued
heavy spark knock at high speeds can cause
damage, and immediate service is required.
Poor quality gasoline can cause problems
such as hard starting, stalling, and hesita-
tions. If you experience these symptoms, try
another brand of gasoline before considering
service for the vehicle.
Ethanol
The manufacturer recommends that your ve-
hicle be operated on fuel containing no more
than 15% ethanol. Purchasing your fuel from
a reputable supplier may reduce the risk of
exceeding this 15% limit and/or of receiving
fuel with abnormal properties. It should also
be noted that an increase in fuel consump-tion should be expected when using ethanol-
blended fuels, due to the lower energy con-
tent of ethanol. Problems that result from
using methanol/gasoline or E-85 ethanol
blends are not the responsibility of the
manufacturer.
CAUTION!
Use of fuel with Ethanol content higher
than 15% may result in engine malfunc-
tion, starting and operating difficulties,
and materials degradation. These adverse
effects could result in permanent damage
to your vehicle.
FUEL REQUIREMENTS —
DIESEL ENGINES
Use Premium Quality Diesel fuels with a
Cetane rating of 50 or higher, and meeting
the EN590 standard are highly recom-
mended. See your authorized dealer for fur-
ther information regarding fuels available in
your area.

CYBERSECURITY
Your vehicle may be a connected vehicle and
may be equipped with both wired and wire-
less networks. These networks allow your
vehicle to send and receive information. This
information allows systems and features in
your vehicle to function properly.
Your vehicle may be equipped with certain
security features to reduce the risk of unau-
thorized and unlawful access to vehicle sys-
tems and wireless communications. Vehicle
software technology continues to evolve over
time and FCA US LLC, working with its sup-
pliers, evaluates and takes appropriate steps
as needed. Similar to a computer or other
devices, your vehicle may require software
updates to improve the usability and perfor-
mance of your systems or to reduce the po-
tential risk of unauthorized and unlawful ac-
cess to your vehicle systems.
The risk of unauthorized and unlawful access
to your vehicle systems may still exist, even if
the most recent version of vehicle software
(such as Uconnect software) is installed.
WARNING!
• It is not possible to know or to predict all
of the possible outcomes if your vehi-
cle’s systems are breached. It may be
possible that vehicle systems, including
safety related systems, could be im-
paired or a loss of vehicle control could
occur that may result in an accident
involving serious injury or death.
• ONLY insert media (e.g., USB, SD card,
or CD) into your vehicle if it came from a
trusted source. Media of unknown origin
could possibly contain malicious soft-
ware, and if installed in your vehicle, it
may increase the possibility for vehicle
systems to be breached.
• As always, if you experience unusual
vehicle behavior, take your vehicle to
your nearest authorized dealer immedi-
ately.
NOTE:
• FCA or your dealer may contact you directly
regarding software updates.• To help further improve vehicle security
and minimize the potential risk of a secu-
rity breach, vehicle owners should:
–Routinely checkwww.driveuconnect.eu
to learn about available Uconnect soft-
ware updates.
– Only connect and use trusted media
devices (e.g. personal mobile phones,
USBs, CDs).
Privacy of any wireless and wired communi-
cations cannot be assured. Third parties may
unlawfully intercept information and private
communications without your consent. For
further information, refer to “Onboard Diag-
nostic System (OBD II) Cybersecurity” in
“Getting To Know Your Instrument Panel” in
your Owner’s Manual.
