Late 2016 and Newer GEM Gauge Overview

New body style GEM vehicles (late 2016 and newer) are equipped with a digital/analog gauge, as shown below. The gauge is made up of a speedometer, indicator lamps and Rider Information Center.


When driving, the speedometer displays the vehicle's speed in either miles per hour (mph) or kilometers per hour (km/h). See below for how to change from mph to km/h.

To toggle through mode options, use the MODE button, pictured below. 

Mode button

Here is a look at the indicator lamps found on your GEM:

Lamp Indicates Condition
Vehicle speed icon Vehicle
When standard mode is selected, speed displays in miles per hour. When metric mode is selected, speed displays in kilometers per hour.
Brake icon Brake
The brake indicator illuminates when the park brake is engaged or when a brake system failure has occurred. If the brake warning illuminates inspect the brake system before operating your vehicle. If the parking brake is engaged, release it. Check the brake fluid level. If it's low, add brake fluid. Check the hoses for cracks, scuffs and worn spots. If you discover signs of wear or damage, do not operate your vehicle. Your GEM Dealer can provide service. For more on brake maintenance, see your Owner's Manual.
Direction icon  Direction 
A direction indicator flashes when a turn signal is active.
Low beam icon Low
This lamp illuminates when the headlamp switch is set to low.
High beam icon High
This lamp illuminates when the headlamp switch is set to high beam.
High beam icon Seat Belt When the key is turned on, the seat belt indicator lamp will illuminate if the driver's seat belt is not fastened. The lamp is a reminder to the operator to ensure all riders are wearing seat belts before operating.
Vehicle fault icon Vehicle Fault This lamp illuminates when the vehicle has a fault. When this illuminates for a fault condition, the wrench icon in the Rider Information Center (described below) also will flash.

 The Rider Information Center is located in the instrument cluster. All segments of the Rider Information Center will light up for one second when you start the vehicle. If the instrument cluster fails to illuminate, a battery over-voltage may have occurred and the instrument cluster may have shut off to protect the electronic speedometer. if this occurs, your GEM Dealer can provide a proper diagnosis.

The information center is set to display standard units of measurement and a 12-hour clock at the factory.

Making up the Rider Information Center, as illustrated below, are the Information Display Indicator (1), the Drive Mode/Drive Selection Indicator (2), the State of Charge Indicator (3), the Miles/Kilometers Indicator (4) and the Fault Indicator (5).

Rider Information Center

The information display is where the clock, odometer, trip meter, state of charge, range meter, efficiency rate (EFF) or any existing fault codes or warnings messages will be displayed.

The odometer displays the distance traveled by the vehicle since manufacture.


The trip meter displays distance traveled since the last reset of the trip meter. To reset, toggle to the trip meter display. Press and hold the MODE button until the meter resets to zero.

Trip meter

The battery state of charge mode displays the remaining system voltage level in percentage format.

State of charge

The range meter displays the approximate distance the vehicle could travel on the remaining battery voltage level.

Range meter

The efficiency rate displays the rate at which electrical power is consumed per mile or per kilometer. A higher number indicates less desirable efficiency. A lower number indicates better efficiency.

Efficiency rate

The miles or kilometers indicator (4) illuminates to indicate the mode of measurement selected.

The display can be changed to show either standard or metric units of measurement for each of the following settings.

Measurement Standard Display Metric Display
Distance Miles Kilometers
Temperature Fahrenheit Celsius
Time 12-Hour Clock 24-Hour Clock

To change standard to metric:

1. Turn the key to the OFF position.

2. Press and hold the MODE button while turning the key to the ON position.

3. When the display flashes the distance setting, tap the MODE button to advance to the desired setting.

4. Press and hold the MODE button to save the setting and advance to the next display option.

5. Repeat the procedure to change the remaining display settings.

To exit the set-up mode, turn the key off. Wait 5 seconds and then turn the key on. The gauge displays the mode that was displayed prior to setting the units.

For more information, read Setting the Clock on Your GEM.

When both the chassis fault lamp and the fault indicator (5), the wrench symbol, illuminate, use the MODE button to toggle to VEH FLT on the display. Then press and hold the MODE button for 3 seconds to access the currently active trouble codes. pressing the MODE button momentarily will toggle through all current trouble codes. Your authorized GEM Dealer can provide code details and diagnosis.

The drive mode/direction selection indicator (2) displays the drive mode. 

  • F = Forward
  • N = Neutral
  • R = Reverse (flashing)
  • C = Charging

The state of charge indicator (3) illuminates when the key is turned on. It also illuminates 8 to 10 seconds after the charging cord is connected, turning off when the batteries are 100 percent charged. To verify a full charge or to check the state of charge, turn the key on. As charge is depleted, illuminated bars being to turn off from right to left. Remaining bars indicate the remaining battery charge, which is shown in the below table.

Bars Percentage of Charge Remaining
1 Less than 10
2 10 to 20
3 20 to 30
4 30 to 40
5 40 to 50
6 50 to 60
7 60 to 70
8 70 to 80
9 80 to 90
10 90 to 100

Cold weather can have a drastic effect on all electric vehicles. The colder the ambient storage temperature, the slower the rate of charge and discharge of batteries. In the application of an electric vehicle like a GEM, cold weather will drastically decrease the achieved range on a charge.

GEM vehicles with lead-acid batteries do not factor battery temperature into state of charge. If batteries are stored at cold temperatures, the amount of available stored energy on a full charge is reduced. This is most pronounced at temperatures below 32 degrees Fahrenheit (0 degrees Celsius).

If a user is completely reliant on the battery meter's state of charge for determining range, GEM recommends that the vehicle be charged and stored in a location where the temperature is at least 50 F before use. When the vehicle has been stored in a warm location, the vehicle's battery meter will display a more accurate state of charge; even if the GEM is used in colder temperatures, as long as it is used periodically and does not sit idle for an extended period.

If your GEM cannot be stored in a warm location, a user can estimate vehicle range being reduced approximately 10 percent for every 15 degrees below 80 F as captured in the table below. The temperature column refers to the ambient temperature that a vehicle was stored in.

Temperature (F / C) Battery Capacity (%)
80 / 27 100
65 / 18 90
50 / 10 80
35 / 2 70
20 / -7 60
5 / -15 50
-10 / -23 40
-25 / -32 30

Vehicles equipped with Li-Ion batteries also will experience range reduction due to cold, but the state of charge is more accurately captured on the vehicle display.

There are many things that can affect a vehicle's range on a charge: driving style, terrain, increased vehicle payloads, cab heater usage and other electrical accessory usage. Even though things like these can decrease a vehicle's range, they should be accounted for in the state of charge reading.

For more on your GEM, including maintenance tips, procedures and specifications, consult your Owner's Manual or see an authorized GEM Dealer.

Note that high water pressure may damage gauge components. Wash the vehicle by hand or with a garden hose, using mild soap. Certain products, including insect repellents and chemicals, will damage the speedometer lens and other plastic surfaces. Do not use alcohol to clean the instrument cluster. Do not allow insect sprays to contact the lens.
